led – the future of lighting
We know the whole spectrum
“LED’s greatest advantage is also its greatest challenge. Balancing efficiency with ergonomics. Combining good economy and lighting comfort. And we’re there now.”

It’s a bright new world. LED has revolutionised the lighting
landscape; high light flows ensure superb efficiency and
economy, with a life span of tens of thousands of hours.
From what was previously the domain of decorative ac-
cent lighting, LED technology has evolved into a practical,
general lighting option. To truly embrace the benefits of
LED, and to address the challenges they pose, requires
completely new luminaires, rather than just changing the
light source. Fagerhult are developing luminaires specifi-
cally for LEDs, creating viable solutions across the whole
spectrum of a lighting project. Drawing on over half a
century of lighting know-how and innovation, this ap-
proach has focused on softening the intensity of the light
to create a harmony between efficiency and comfort.
What’s the point of efficient lighting if no
one is there?
In the early days of T5 fluorescent tubes it was apparent
that high levels of light require new reflector solutions to
maximise the efficiency of the light source, while reducing
glare. T5 offered an increased luminance from 14,000 cd/
m² to 17,000 cd/m². With LED, this has rise to 300,000 cd/
m². LEDs produce an intense light which can be harsh on
the eye unless managed correctly. And what is the point of
saving money on lighting if no one can stand to be in that
room? Fagerhult’s innovative glare-reduction technology
circumnavigates these issues, taking full advantage of the
efficiency whilst ensuring user comfort.
New concepts in luminaire design
Free from the shackles of the specific shape or size of the
light source dictating design, luminaires can become smal-
ler, slimmer and more unpredictable. Fagerhult’s Freedom
luminaire takes this concept to the extreme. Combinations
of linear or circular housing can be used in numerous con-
figurations, offering the designer the opportunity to draw
their own lines in light.
No one would dream of putting a fluores-
cent tube in a candleholder
And, by the same token, it is not possible to get the best
out of LEDs if the luminaire was not designed for that
technology. It requires the right design, ballast and cooling,
to guarantee the level of efficiency and life span that ma-
kes the investment worthwhile.
The whole spectrum is what matters
From recessed modular fittings and downlights, through
to accent lighting and interior design, Fagerhult offers a
wide range of LED solutions suitable for various applica-
tions.

challenge. Balancing efficiency with ergonomics.

we’re there now.”

It provides light, but is not a light source in the traditional
sense. It can reproduce all the colours in the light spec-
trum, it works best in groups and, in just a few years, has
revolutionised the lighting industry. This is LED.
An acronym light-emitting diode, an LED is a semiconduc-
tor that radiates light when subjected to electrical impul-
ses – a phenomenon called electroluminescence. An LED
runs on direct current (DC) and often requires a separate
electrical ballast – a ‘driver’. The driver converts the mains
voltage to an optimal level for the LED.
An LED consists of two sections: one with an excess of
electrons (n-conducting) and one with a shortage of elec-
trons (p-conducting). The light is generated when these
electrons strive to achieve balance. The boundary between
these two areas is called the p-n junction or depletion
layer, and this is where it all happens. When direct current
is connected to the diode, the excess and shortage balance
out to create light.
The wavelength of the light emitted, and thus its colour,
depends on the materials the LED is made of. The main
colours are red, orange and green, and a variety of shades

of blue. The most common way to create a white light is
to apply a phosphor-based coating to a blue diode. The
phosphor converts the blue light to white light in a range
of colour temperatures. The quality of the white light is
affected both by the choice of LED and by the properties of
the phosphor.
LEDs are very small; the active light-emitting surface is
no bigger than 1–2 mm². A single diode can rarely produce
enough light for a given lighting situation. For the unit to
work, it must be mounted on a circuit board, with multiple
LEDs combing in a cluster to form a LED module (not to
be confused with retrofitted light sources). LED modules
come in many varieties with specially adapted light flow
and design to suit specific types of luminaires. The instal-
lation and maintenance of most these modules often
require professional services, however; some modules are
easier to manage and can be taken care of by traditional
maintenance methods.

LED. Application areas
LED is still in an early stage of development; we can expect
a future in which LED is the natural choice for many more
applications than today.
Indoor
In public environments, such as offices and schools, LED’s
have previously been used for more decorative purposes,
such as accent lighting or colour-
shifting effects; replacing low-
voltage halogen light sources in
these contexts.
Now LED technology has achieved
sufficient quality, energy efficiency and life span to surpass
traditional solutions for general lighting as well. New
reflector and anti-glare technology harnesses the huge
light flows offered by LED while still making it comfortable
for people to be in the room. In corridors, offices, entry
halls and conference facilities downlights and T5 solu-
tions can be replaced with new LED technology such as
Fagerhult’s downlight range Pleaid G3 and the recessed
general lighting system Multilume Flat. Outside of these
applications the absence of UV or IR radiation in LED’s
safeguards against degradation of works or art, artefacts
or food products and their extended
lifespan offers the potential to save
on the labour and materials costs
associated with maintenance. In
contrast to traditional light sources,
LEDs achieve full
brightness immediately and, in fact, the life span of the
diode is increased by frequent switching on and off.
LED luminaires are an ideal
replacement for both downlights
and T5 solutions.
7. 7
Retail
The LED technology of today already has many benefits
which can help create enhanced dynamic in-store lighting
concepts, with the trends and possibilities set to continue
to develop in the future.
Adjustable, white LED light, which changes the colour
temperature between warm and cold (2700 K–6500 K), are
already a commonly used solution. Ideal for fittings rooms
where clothes can be viewed in different lighting situa-
tions, LEDs can be positioned behind the mirror as a more
discreet alternative to the fluorescent tubes previously
used in this concept. Similarly, the small size of the LED
light source makes it very useful to integrate into shelves
and displays, as well as for illuminating products in small
spaces.
Adjustable white LED light is also an asset in the shop
itself, allowing staff to adjust the colour temperature to
the season. Warm white light creates a welcoming at-
mosphere in winter, while cold white light creates a cooler
impression in summer. And when it comes to simulating
natural daylight within artificial windows and walls, this
light source is also superior. The moving fluctuations are
far more natural that what any other light source could
present.
Sometimes a lighting concept may need a little so-
mething extra and coloured effect lighting can be just
the thing. Using RGB LEDs can create a dynamic and
effective lighting concept with feeling. Different colours
trigger different emotions; green signals well-being and
has a calming effect; yellow creates energy, blue cools and
red signals passion. LED opens the door to new ways of
creating mood and impressions for different occasions. A
control system lets you adjust, dim and change the colour
of the lighting.
The directivity and optical efficiency of LED, in combina-
tion with lenses and reflectors, make it an ideal technology
for spotlights. Often better than a traditional solution, it is
relatively simple to achieve the desired lit effect using less
power. LEDs with a cold white light are even more effective
and are the preferable solution where this type of lighting
is suitable, for example in a refrigerated display case.
Outdoor
In general, LED technology is the optimal alternative for
outdoor lighting. These luminaires are subject to the
vagaries of weather, temperature, vibrations and human
interference. Often the systems are designed so that
special equipment is needed to conduct maintenance and
replace broken components. The reduced maintenance
characteristic of LED technology is both a practical and
economic solution. Another advantage of LED lighting in
outdoor environments is that cold temperatures actually
have a positive effect on the diodes, enhancing light flow
and life span. This, when compared with a light source
with an aluminium housing , offers an extremely durable,
reliable, maintenance-free luminaires that require a mini-
mal amount of electricity in relation to the amount of light
they generate.
LED solutions are superior for simu-
lating natural light through artificial
windows and on walls.
Cooler outdoor temperatures have a
positive effect on LEDs, enhancing light
flow and life spans.
8. 8
The way LEDs emit light when stimulated with electricity
differs from traditional light sources, in which the light
is a by-product of the filament being heated or of a gas
discharge. Unlike traditional light sources, an LED contains
no mercury, making it a better choice in terms of the envi-
ronment and recycling. Altogether, LED technology provi-
des many advantages in terms of function and design.
Because LEDs do not emit ultraviolet (UV) or infrared (IR)
radiation, the technology is extra well-suited for lighting
in sensitive environments. Museums and exhibitions of
art and artefacts, as well as grocery retailing with food
displays, are just a few examples.
In contrast to traditional light sources, LEDs achieve full
brightness immediately and, in fact, the life span of the di-
ode is increased by frequent switching on and off. Equally
the light flow increases at lower ambient temperatures,
so luminaires with LED technology are the ideal choice for
refrigerator or freezer rooms and outdoors.
LEDs do not contain any moving or fragile parts. There-
fore, a properly designed LED luminaire is well-equipped to
handle vibrations and other mechanical stress.
.
Advantage LED. Differences compared to traditional
light sources
9. 9
Energy efficient, reliable and long-lasting. In many ways
LED technology is superior to traditional light sources.
But to really make the most of the technology, you need
luminaires that were developed especially for LEDs.
There are many types of retrofit LED light sources on the
market which can be used to replace traditional sources,
for instance cold halogen lamps (HRGI) of up to 50 W and
other types of halogen lamps. Some of these models also
offer brightness adjustment. This type of light sources can
be used in locations where light flow, light quality and ef-
ficiency are lower, for example in a home environment.
From a short-term capital outlay perspective it may appear
more profitable to simply replace the light source within
the existing luminaire to LED, however there are factors
which need to be taken into consideration.
No product standard
In areas which place a high importance on light output
and quality, retro-fitted LEDs are not always suitable. There
are LED tubes on the market that are designed to replace
T8 fluorescent tubes (26 mm) and run on conventional
lighting ballasts. As the scheme was originally designed
for a traditional light source- switching to LED may conflict
with the original lighting design.
There are currently no product standards for this type
of LED tube, nor are they covered by the standards for the
LEDs. Some variants have been found to have structural
flaws that make them dangerous, prompting the Swe-
dish National Electric Safety Board to force suppliers to
withdraw them from the market. An important considera-
tion when retro-fitting LED light sources is that responsibi-
lity for the entire luminaire passes over to the person who
replaces it as the existing fixture has been tampered with.
Retrofitting. Is it enough to simply replace the
light source?
When you install LED tubes in an
existing system, you take over the re-
sponsibility for the entire luminaire..
10. 10
As electricity prices rise, low power consumption becomes
increasingly important. LED is superior to all other alterna-
tives on the market in terms of energy efficiency and life
span. But how much can we really ask?
Comparing LED with traditional solutions can easily turn
into a matter of apples and oranges. The properties me-
asured in the laboratory of an LED manufacturer cannot
be directly linked to how an LED module performs in a
luminaire. To get a good idea of the light’s capacity, the LED
needs to be placed in its specific lighting context.
Light output equals light flow
The energy efficiency of luminaires with traditional light
sources is described in terms of light output ratio (LOR).
The LOR is measured by comparing the light flow (also
known as luminous flux) from a freely glowing reference
light source with the measured luminous flux from the
LED. The economical alternative
luminaire. But the energy efficiency of an LED luminaire
cannot be defined by light output, because LED modules
do not have a standardised nominal luminous flux as
fluorescent tubes do. The reason for this is that the whole
luminaire, including the LED and the electrical ballast, is
counted as a reference, with the result that the light out-
put is always 100%. Instead, the efficiency of an LED lumin-
aire is defined as the ratio of the total measured luminous
flux (lm) to the radiant flux including ballast (lm/W).
Coloured light at no additional cost
One of the advantages of LED is that the technology can
produce coloured light without using a filter, which saves a
lot of energy. For instance, with a traditional spotlight ad-
ding a colour filter can reduce the light flow by up to 90%.
With an LED, the colour of the light is determined by the
material it is made of.
An LED luminaire can have a very long life span – assuming that it is well-
designed and has high-quality components.

Suited for many types of luminaires
While the rapidly improving luminance from white LEDs
opens up exciting possibilities in luminaire design, it’s
important to distinguish between the data for individual
LEDs and those for a complete luminaire solution. The data
provided by manufacturers of LEDs or LED modules nearly
always refer to the maximum luminance of a cold LED.
They take no consideration of losses due to higher tempe-
ratures, the power consumption of the electrical ballast
or losses in reflectors or lenses. The luminance of a poorly
designed LED luminaire, or one running on a poor-quality
ballast, may be less than half the nominal value of the LED.
In public environments, such as offices and schools,
LED’s have previously been used for more decorative
purposes, such as accent lighting or colour-shifting ef-
fects; replacing low-voltage halogen light sources in these
contexts.
Now LED technology has achieved sufficient quality,
energy efficiency and life span to surpass traditional solu-
tions for general lighting as well. New reflector and anti-
glare technology harnesses the huge light flows offered
by LED while still making it comfortable for people to be in
the room. In corridors, offices, entry halls and conference
facilities downlights and T5 solutions can be replaced
with new LED technology such as Fagerhult’s downlight
range Pleaid G3 and the recessed general lighting system
Multilume Flat.
At least 50,000 hours
An LED luminaire can have a very long life span – assuming
that it is well-designed and has high-quality components.
An LED very rarely breaks although, as with any electro-
nic products, there is a normal failure rate. Rather than
breaking, an LED generates reduced light flow over time.
Life expectancy is defined as when the light from the
lamp goes down to 70% of the initial value. The Life span
is expressed as L70
, followed by the number of hours. The
standard life span of most LED luminaires is L70 50,000
hours, but there are deviations both upwards and down-
wards. The expected life span is affected by several factors:
• Choice of LED (manufacturer and type)
• How hard the chosen LED is run (that is, how high a cur-
rent it runs on)
• Luminaire design (considering the temperature of the
LED or LED module)
• Choice of ballast (driver)
• The environment where the product is installed
• Other materials used in the design
Once the L70
life span is reached, the LED still continues to
produce light for a long time but with a further reduction
in light flow. Therefore, to maintain the required levels, the
module or entire fitting should be replaced at this point.
After a projected 15–20 years of operating time it may
well be worth changing the entire system as newer, more
efficient technology will be available.
Schematic sketch of losses. This illustration shows the process from the indivi-
dual LED, through heat losses in the modules (where the diodes heat each other
up), to light losses in lenses, reflectors and ballasts, to the light that actually
radiates from the luminaire. Depending on the design, each loss can be of
greater or lesser magnitude.
With the development of new technology and increasing efficiency, the prices
of LED components have been steadily dropping for some time, but this is
expected to stabilise. This graph shows what has happened so far and the
projected cost p/ lm of an LED module.
12. 12
How to calculate expected life span: After 50,000 hours, about 70% of the
light flow remains (L70
50,000 h).
Maintenance-free
Outside of standard cleaning, LED luminaires are pretty
much maintenance free throughout their lifecycle. As
such, larger organisations can save considerable amounts
by not having to keep stock of equipment and associated
man-power in replacing the light sources.

From an environmental stance the energy efficiency and
long life span are the two key benefits of LED. At the end of
its life an LED module is recycled in the same way as other
electronics. Although unlike traditional light sources, such
as fluorescent tubes, LED modules contain no mercury,
which simplifies waste management and reduces the risk
of emissions.
Superior efficiency
As with all lighting, the greatest impact on the environ-
ment is related to the energy used during its use. The
large amount of light produced, compared to the energy
consumed, makes LED solutions very efficient, this is
particular important when the electricity used to power
then comes from sources that are not environmentally
optimised, such as coal. There are a selection of products
that produce more than 200 lumen per watt in laboratory
environments, however, these LEDs are not yet ready for a
commercial launch.
The environmental effect of reduced power consumption is significant – in parti-
cular when the electricity comes from power sources that are not environmentally
optimised.
Less waste
The life span of an LED module greatly exceeds that of a
traditional light source. This leads to reduced consumption
of raw materials, less throwing away and less strain on
the recycling system. However, the environmental impact
of an LED luminaire in terms of energy efficiency and life
span is always dependent on how the luminaire is desig-
ned and what context it is intended to be used in. Thus, it
is important to do calculations on each individual project
and not blindly trust laboratory tests.

Light quality
Many factors affect the light quality of LED. Colour tem-
perature, colour rendition and colour quality all impact
how the light works and how it is perceived. Although
the technological properties of LED’s and traditional light
sources are not directly comparable, the user’s demands
for how the light from a good luminaire should behave,
remains unchanged.
Colour temperature
The colour temperature of a light source is given in Kelvin
(K). Originally, Kelvin was a measure of the colour of a
heated (and therefore glowing) black body. For lamps with
a filament, this measure is easy to apply, as the colour
temperature in Kelvin is the same as the actual tempe-
rature of the filament. For light sources with no filament
– such as fluorescent tubes, gas discharge lamps and
LEDs – we must calculate a correlated colour temperature
(CCT) in Kelvin. The instruments and measures available
today were developed for traditional light sources and
not specifically for LED, so the International Commission
on Illumination (CIE) has begun to develop new methods
of measuring. Colour temperature may vary from one
manufacturer to another even if they report the same me-
asurement. In addition, the colour temperature of an LED
can change over time, which means that the value after
several thousand hours of use will not be the same as that
for a new product.
When LEDs are produced, their colour temperatures and
luminous flux vary widely, making it preferable to choose
from a limited assortment. Manufacturers sort their pro-
ducts into ‘bins’ according to their performance. The fewer
bins your LEDs are selected from, the more stable the
quality of the product. The closer the selection the more
the supply decreases and the cost increases, therefore lu-
minaire manufacturers tend to accept diodes from nearby
bins as well.
Variations in white light
Usually white light is created by applying a phosphor-
based coating to a blue diode, either directly on the diode
or on a separate plate over it. This coating converts some
of the blue light to white light of various colour tempe-
ratures – a process that is reminiscent of how a standard
fluorescent tube works. The quality of the light is determi-
ned both by the specification of the blue LED and by how
carefully the phosphor is matched to the selected diode.
White diodes come in a wide range of colour temperatu-
res, from warm white to very cold (2700–8000 K). Because
a blue LED is the basis of the white light, efficiency is
greater for colder colour temperatures. To obtain a warmer
It is important not to focus too heavily
on the replacement value when con-
sidering both colour temperature and
colour quality. Also look into how the
quality changes during the product’s ex-
pected life span.
This illustration shows how to calculate a correlated colour temperature: The
filled-in curve shows the colour temperature in actual Kelvin degrees. The
chromaticity of the light source is measured on one of the isothermal lines
and the correlated colour temperature is the point where the line crosses the
curve.
How to create white light from a blue diode, or in the case on the right, from
a cluster of diodes. On one individual LED, the phosphor covers the diode; in
a module, the phosphor is placed on a plate that covers all the diodes in the
module.

colour temperature, the phosphor must convert a larger
proportion of the original blue light.
Colour rendition
Colour rendition in LEDs is not exactly the same as in tra-
ditional light sources, but it is still described as Ra/CRI. The
Ra scale is from 1 to 100 and measures the capacity of the
light source to render colours. Depending on your choice
of LED, the degree of colour rendition (Ra) normally varies
from 60 to 95. A high Ra often produces a somewhat lower
luminance.
Normally, colour rendition is measured using the CIE
method on a scale of eight colours (see illustration).
The Colour Rendering Index (CRI) is given as an average
value (Ra), so it is possible for a light source to be good at
rendering seven colours but not as good at the eighth. A
complementary scale is called CRI 1-14, which contains six
more colours. As the illustration shows, this LED cannot
render the bright red colour, number nine, in an optimal
way. In consequence, the average CRI 1-14 value is lower
than the average for CRI 1-8. Regardless of the average
value, we can see that the LED does not give an ideal ren-
dering of the red scale.
Colour rendition can vary among LEDs from different
manufacturers, but is linked to the spectral distribution of
the LED. Therefore, an analysis of the spectral distribution
can give us more information about the LED’s ability to
reproduce colours. It is also worth noting that colour rendi-
tion can differ between a new LED and one that has been
in use for several thousand hours.
16. 16
Chromaticity
The chromaticity of an LED product – that is, degree of de-
viation of its colour temperature – is defined in MacAdam
ellipses in Standard Deviation of Colour Matching (SDCM)
as per the CIE 1964 standard. The MacAdam system origi-
nates from the United States and ranks colour quality on a
scale of 0 to 10.
Between 0 and 4 is it difficult to see differences in co-
lour, but further up the scale it can have an
obvious and negative disparities.The
problems are greatest when lighting
a white surface, or placing a LED
strip very close to a white wall. The
requirements for most other Indoor
environments are usually around
MacAdam 3-5 SDCM. By compari-
son, a T5 fluorescent tube from the
major manufacturers is about Ma-
cAdam 4. For exterior applications,
a rating of MacAdam 7 SDCM is
perfectly OK.
One of the key considerations is how the colour qua-
lity of a product changes throughout its lifespan. Some
LED’s can maintain a very high colour quality for the first
thousand hours but then deteriorate rapidly. The design of
the luminaire is another critical factor, where insufficient
cooling, or the LED being run too hard, can both have a
negative impact.

Pleaid SLD G3 has a MacAdam value of 3, avoiding the irritating colour differences which can appear with poor quality LED’s. These disparities are more noticea-
ble on white surfaces.
Large variation in colour quality results in a larger ellipse and a higher MacA-
dam value. The size of the ellipse is calculated using a formula.
Methods of documentation
Despite the lack of all inclusive standards, the European
organisation for luminaire manufacturers, CELMA, has
proposed a number of parameters and methods of measu-
rements for the documentation of LED luminaires. While
it can be viewed as a temporary stop-gap pending the
establishments of international standards, these parame-
ters will, in all likelihood, be included in future IEC and CEN
standards.
The main purpose of uniformed reporting to allow an
accurate and fair comparison between different manu-
facturers and solutions, while highlighting the pertinent
information which should be collected from manufactu-
rers outside of CELMA.

The design of an LED luminaire intended for working environme-
nts is a careful balancing act between comfort and economy.
Visual comfort
The great challenge with LEDs is to keep glare within
reasonable levels. It is not unusual that diodes and LED
modules have a luminance (light intensity) of over 300,000
cd/m². In contrast, a standard T5 fluorescent tube has a
luminance of 17,000 cd/m².
Luminaire developed for working environments are a
careful balancing act between comfort and economy. From
a financial stance, creating a naked LED module with a
cooling unit and external driver would deliver the highest
lumens to watts ratio. However, this solution would be
completely impractical. The greater the efficiency the great
the glare, a factor which should be considered in both the
development and selection of luminaires.
In commercial environments the light from an LED or
LED module has to be controlled by reflectors, lenses, or
some other form of diffusing material. Lenses are usually
directly linked to different manufacturers and the type of
LED. The choice of reflector material or lens used is crucial
to maintaining the luminaire’s efficiency while keeping the
luminance sufficiently low.
20. 20
Electrical ballast and operating temperature
run on a constant 350, 500, 700 or 1050 mA of current
and are serially connected to the ballast. The voltage in
the circuit depends on the number of diodes: the forward
voltage of each diode is added to the next in the series. A
downlight with three LEDs intended to run on a constant-
current ballast will have a secondary voltage of about 9 V
DC (3x3 V). If several luminaires are serially connected to
a single ballast, the voltage is multiplied by the number of
luminaires.
SELV technology limits the number of diodes that can be
serially connected because too many will lead to exces-
sive secondary voltage. In addition, it is unlikely that the
ballast has the capacity for such a high voltage or power.
In a constant-current system, the
LEDs are serially connected to bal-
lasts.
In a constant-voltage system, the
LEDs are parallel connected to
ballasts.
The ballast is the heart that drives an LED. Different lumin-
aires uses different ballasts and if the ballast is unsuitable,
or improperly connected, it can damage or even ruin the
LED luminaires connected to it.
LEDs and LED modules require special electrical ballasts, or
drivers, which converts 230 V of mains voltage to suitable
values to operate the component. Most of these are also
designed as Safety Extra Low Voltage (SELV) systems, which
means that the LED and other components do not need
touch protection.
The disadvantage of SELV systems is somewhat lower
efficiency due to losses in the protective separation. Lu-
minaires without SELV are only designed to shelter the LED
modules and wires from touch and therefore require a tool
to access the components.
Current or voltage
LEDs can be powered in two ways: with constant current or
constant voltage. Constant current means that the diodes
21. 21
SELV limitations in EN 60598-1 (luminaire standard): For IP
20 luminaires the limit is 60 V DC, and for luminaires with
a higher protection class than IP 20 the limit is 30 V DC.
This is assuming that the diodes are accessible to touch. If
they are shielded, the permitted voltage is 120 V DC, but
the certification of the luminaire and the recommended
ballast must be considered.
Constant current is usually used for LED products with
a large number of diodes, such as LED strip lights and pro-
ducts that produce a glowing line. The LEDs are connected
parallel to ballasts. The constant voltage is usually 8, 10,
12, 24 or 48 V DC. Several LED products can be connected
parallel to a single ballast, as long as the ballast has the ca-
pacity. The voltage drop in the wires is estimated to be the
same as in traditional extra-low-voltage installations
Use the right ballast
Regardless of the type of power source, it is important that
the ballast is suited to the specific type of LED luminaire.
The polarity is also important because this is direct current
(DC). If the ballast is unsuitable or improperly connected,
it can damage or even ruin the LED luminaires connected
to it.
It is important that the ballast is designed for and
approved to operate LEDs. Although some LEDs can run
on conventional transformers, such transformers can lack
certain kinds of safety features, such as short-circuit pro-
tection, which can lead to injuries.
22. 22
Operating temperature
Traditional light sources always radiate heat. While an LED
itself doesn’t it is still a problem. Unlike traditional light
sources, which are cooled by ambient air, the LED must
be cooled by the material behind it. Heat has the greatest
negative impact on an LED’s life span, luminance and ef-
ficiency. This is why Fagerhult makes sure when developing
LED luminaires that the temperature of the components
remains within the manufacturer’s specifications and
meets the requirements in our own policy.
Fagerhult’s LED policy
Fagerhult uses only LED’s, or LED modules, from recognised
manufacturers and pay close attention towards ensuing
they are powered for optimal lifespan and efficiency.
To help safeguard against the negative issues related to
excessive heat all components within the Fagerhult range
remain within the manufacturers stated levels. An addi-
tional safety margin is added when measuring the control
temperature (tc) and when calculating the temperature of
the LED (tj). This policy has been applied to other elec-
tronics, such as high-frequency ballasts and emergency
lighting, for many years and has helped ensure the stated
expected life span is always achieved by a good margin.
The design is optimised by using software that stimulates
temperatures and a heat camera to test calculations on
the luminaire prototypes. During inspections and testing,
the luminaire is always installed in the way it is inten-
ded to be used by the end customer. By including these
processes at the early stage of the design, this additional
margin can be included without increasing the cost of the
luminaire.
23. 23
Control
High-quality LED lighting can be regulated by a range of
control systems. In addition to light intensity timers, day-
light harvesting and proximity control, LED offers comple-
tely new options for controlling the colour of the light.
The regulation of LED light is managed using ballasts
with pulse-width modulation (PWM). The connected load
is run by a technology consisting of a square wave with
varying frequency. The load is switched on and off with a
high frequency, which gives the impression that the light
level changes. PWM ballasts are available with various
types of control interfaces, such as DALI, DSI, DMX 512 and
switchDIM. Separate PWM units are also available, which
can serve as connections between constant voltage and
the load.
Colour shifting RGB/DMX
Colour shifting in red, green and blue is generally referred
to as RGB control. About 65,000 colours can be obtained
by mixing and combining these three colours at various
strengths. Creating a specific colour requires some type of
control unit or interface to a program that communicates
via DALI or DMX 512. The control unit might be a lighting
desk – which is unusual in many applications – a router or
some kind of control panel.
People often make an association between DMX, RGB
and LED. A simple description of DMX is a control unit that
controls all electrical loads. DMX 512 is a standard pro-
tocol that was initially developed to control lighting and
dimmers in theatrical environments via a lighting desk.
It has a high rate of transfer, which requires high-quality
installations, wiring and connections. However, with the
development of new light sources and the desire for colour
in various applications, DMX control has come into use in
many other environments.
DMX is advancing
DMX is also available in a recently updated version, RDM,
which allows you to address loads via the DMX wiring, as
long as the loads and software are correctly selected. The
most common way to address DMX is with a DIP switch
setting on each unit. (RDM is currently employed in such
products as Fagerhult’s Pleiad LED Wallwasher with Lexel.)
DMX compared to DALI
There are more differences than similarities between DMX
and DALI. DALI was developed with a focus on energy-
efficient fluorescent-tube lighting in public environments
where people work and visit. It has been a very popular
alternative considering its limitations, but its simplicity
was the key. Multiple control units can control all or part
of the electrical loads. In the not-too-distant future, the
current DALI standard will be expanded with DALI Colour
Control Command.

Greater efficiency, lower prices and better applications of the tech-
nology will contribute to steadily growing demand for LED.

LED – a glimpse of the future
Advances in the LED field are astounding. Efficiency has
doubled in just a few years, while costs have dropped
dramatically. But what happens next?
This development is likely to continue, even if the rate may
slow. It is not unreasonable to expect that LED systems
that produce 100 lm/W today may be up over 150 lm/W
in a year or two. As volumes increase, costs will drop, alt-
hough how much is uncertain.
While there is still a level of uncertainty about the speed
of the growth, the increase in the demand for LED luminai-
res is clear and predictions that LED’s will dominate lumin-
aire sales in 10 years time are far from idle speculation.
One phase in Fagerhult’s further development of this
technology is to research into how people perceive LED
lighting. Early indications point towards LED being percei-
ved as brighter than traditional light sources at the same
levels, which opens up intriguing possibilities for further
energy savings. In addition to research Fagerhult are deve-
loping even more solutions geared towards offering viable
LED alternative for general and workspace lighting. There
is a joint standardisation project being undertaken within
the lighting industry called Zhaga, which is aiming to de-
velop common product standards for physical dimensions
and connections to electrical, photometric and thermal
product standards. This process, in essence, is set to make
it easier to replace LED modules and electronic ballast. The
first standardised modules are expected to be available in
2011

LED technology requires good cooling for optimal per-
formance, which makes it extra useful in cold or well-
ventilated areas. LEDs also lights up quickly, even at low
temperatures. Densus LED is a sturdy lighting solution for
cool spaces, such as refrigeration and freezer rooms, lo-
ading docks and other environments where the luminaire
is switched on and off many times a day.
