How it started?
• Focus on better vision
• Understand how the eye works
• Understand how light works

What is light?
 Light is measured and expressed in lumen (light intensity) and lux (light
per square meter
 Quality of light is measured and expressed in Color Rendering Index (CRI)

The current standard – lighting defined 1931
The eye sensitivity curve V(λ) is based on measurement at photopic light
level measured with a 2° view angle (foveal). CIE standard 1931.
The cones in the eye can see light from blue to deep red with
the highest sensitivity in the green/yellow area. 1Watt energy
converted 100% efficient into light results in 683 lumen.

Eye dynamics
• The human eye perceives light
different under varying intensities or
color
• A lux meter does not show that
• Vision and sight is not the same
under
composed colors
• Leds allow spectral combinations for
optimal vision
• Science is questioning the lumen
standard

Sam Berman, D. Jewett, B.Benson, T.M.Law
Lawrence Berkeley National Laboratory :
“Our results measuring power and pupil size indicate that photopic luminous efficacy
is an inadequate metric by which to judge the efficacy of indoor illumination”

Our eyes behave differently at night than during the day
-- During the day (at Photopic
light levels) our vision is the best
at 555 nanometres
-- in the night (at scotopic light
levels) our visibility is best at 505
nanometres

The Anatomy
• All eyes work the same
around the world
• Cones are for color and
day light = 5,000,000
• Rods are for motion and
night vision = 120,000,000
The retina
Rods
Cones

Light intensity shifts from fotopic to scotopic (very low)

Functioning of the eye is different for Outdoor vs Indoor

Day-light is a sum/ mix of colors

Light is all about understanding the eye
Light is reflected
onto the retina,
signals are being
send to the brain
via the optic nerve
using Cones and
Rods.

The eye needs colors, but the right colors: Ellipz uses
RED+GREEN to create white light
The retina
In the center part of the retina the
‘sensors’ are the Cones and in the
peripherie one uses the Rods. Cones
are 96% RED+GREEN.

Eye-sensitivity curve for the cones = photopic light/day-light. and the
measurement ‘line’ for CRI.
Other industry players (white leds) have a peak at 450Nm due to usage of 3p
and 4p phosphors and therefore have lower CRI and poorer light experience
(cold light).
Ellipz unique combination of Red and Green LEDs provides a different
spectrum leading to higher CRI ratios and higher efficacy (lm/w).

LIGHT & LIFE
Life exists because there is light.
However, our Sun gave us full spectrum of light, which not all are
harmless. Especially the high energy spectrum such as Gamma and X-Ray
are very hazardous. We also know that UV is not good of us if
exposed to it for a long period of time, and to a certain extend Blue
Light as well. Hazard
High Energy Light!

BLUE LIGHT & HUMAN VISION
As such, giving only blue
light to our eyes will not give
us sharp and detailed
vision.
An artistic project in
Amsterdam is stopped as it
is potentially creating
dangerous traffic situations
because of the very blur
vision.
In addition the energy level
of blue light is affecting the
retina and various studies
has shown indications that
blue light may cause
damage to the eye.
Cannot see much if only blue light !

Standard LEDs contain much blue light
This is the typical spectrum of a
standard LED. The blue component
contains high energy.

AMD & BLUE LIGHT
AMD accounts for 50% of all blind registrations in the developed world.
And Blue Light is a main contributor to the problem!
Age-related Macular Degeneration (AMD) is a major health problem in the developed world
accounting for approximately half of all blind registrations.
In recent years there has been a growing awareness of the effects blue light entering the eye
has on the production of Radical Oxygen Species(ROS) in photoreceptor cells and in the
adjacent Retinal Pigment Epithelium (RPE) cells. As well, there is an increased understanding of
the cumulative effects that blue light absorption in the outer retina has on increasing the level of
oxidative stress and resulting chronic inflamation of the outer retina associated with the
development of AMD. This has led a number of researchers to recommend that people reduce
their lifetime exposure to blue light, whether from sunlight or artificial sources. This article discuss
the growing understanding of the mechanisms by which blue light exposure may contribute to
the development of AMD. The discussion on the influence of blue light on the pathogenesis of
AMD that follows below was written a few years ago. This discussion is still valid. The points made
are supported by more recent publications.

In Short
Over exposure to UV and Blue Lights is harmful.
1) UV light is high energy light and promote aging of all material on over exposure.
2) Blue light does not provide sharp vision.
3) The older we get, the less we can see with Blue Light. Worse though is that it
means children are less protected when exposed to high amount of blue light
4) Blue Light potentially causes AMD (Age related Macular Degeneration).

Ellipz was the first to use Red and Green (RBP)
White leds are based on blue chips with 3 or 4
phosphors mixed (Phosphor conversion,
Nakamura concept. Ellipz started Led lighting
based on bare chips (no phosphors),
In 2005 Ellipz presented the first light source
based on green phosphor with red chips.

not determined by the
energy consumption only.
Good LED products offer 80

Traditional methods of producing light
The conventional way of producing light is by burning
From candle light to light bulb to HID.
Candle Light
Burning Wax
Incandescent/CFL
Burning Metal/Gas
HID/HPS
Burning Gas
•Burning process is not efficient
•Consumes high amount of energy to produce light
•Efficiency ~1%

Better Sight With Less Light!
• Best day sight at yellow-green (cones - 555 nm), night vision at blue-green (rods -
505 nm)
• With LEDs, light composition can be chosen more accurate than with
conventional light sources, for instance: green at 509 nm (with 2 nm deviation)
• Light with a green component gives best sight in street lighting at minimum
illumination levels: our visual perception mainly relies on our sensitive rods
Standard

Photopic / Daylight Vision Scotopic / Night Vision

Match the light spectrum with the eye – Ellipz Lighting
• Light spectrum of Ellipz LED light follows the eye cuve which is shifting left from daylight vision
to night light vision.
• Standard Sodium lamps are peaking at 555nm which is good for the lux meter but gives poor
visibility.
• Other Cool-White LED lamps (4000K and above) recreat photopic light with a peak at 555nm
(good for lux meter), but again give poor light due to a peak in the blue area due to the
usage of 3p and 4p phospors.

Color sensation through RED is intenisty and spectrum depending
Low light levels no color vision Ellipz SPD shows colors at 1 lux

Ellipz Mesopic LED-light is adapting to the eye
•Human eye is more
sensitive to green towards
blue at night (Purkinje shift);
• Using yellow or white light
requires higher wattages
to provide good vision;
• For OUTDOOR: Ellipz
produces a green/blue
light to highten visibility at
night at low energy levels;

Something fundamentally wrong !
66
Light directives and standards are based on Photopic
lumen
This is a serious problem because our eyes behave totally
different at night than during daytime.
To benefit of the high sensitivity of the rods, light should
have the right spectral composition at different intensities.
The goal is more sight with less light.
Studies show that the ratio between Scotopic (night) en
Photopic (day) vision, the so called S/P ratio, is a base
which can be used to multiply the lumen with to express
the real light perception.
COMPETITORs White leds are based on blue chips with 3P
or 4P phosphors to convert the blue light into white light
with a peak at 555 nm. In outdoor and most interior
lighting the maximal eye sensitivity is shifted towards 505
nm. Industrial leds produce the lowest output at that
wavelength.

This is what your eyes sees and then it is correct.
Your eyes are not wrong, but measure with the
wrong and outdated standards.

Global Standards in movement (1/2)
Industry focus is on More… More…. More Lm/W Lm/$
Eyes are asking for Better… Better… Better
See better with less energy (=energy saving)
How do we get better light?
By making the right spectral composition: high S/P ratio, best vision, lowest
energy consumption
What is happening to the standards?
IES TM 24-13: adjusting illumination measurement using S/P-ratio
CIE: working on the Mesopic Task-Force
Lites-Asia: twice annual forums discussing S/P-ratio for Asian implementation
SEMIcon SEA: making steps to advice and consult governments
The movement is there to accept the S/P-ratio as a valid
criteria for lighting design and master planning.

Hazards of blue light – out of the visual sphere => light dust
Blue cones in the eye are not in the central focus of the eye. Therefore
blue light is not giving a sharp and detailed vision. An artistic project in
Amsterdam had to be stopped creating dangerous situations. In addition
the energy level of blue light is affecting the retina and may cause
damage to the eye.

SENSITIVITY TO BLUE LIGHT & AGE
Human develop
natural protection
against excess blue
light!
The older you get, the
more blue are filtered!
Elderly people see less,
specially of the blue
light. Glare is therefore
more applicable to
elderly people and
hence impacting road
lighting.

Ellipz Lighting – Following the HUMAN EYE
In view of providing the most optimal light for the human eye, Ellipz Lighting has
developed a 2nd generation of LED ighting technology (SL1, SL2). This is called
Mesopic Light, which is combination of Scotopic (=Moon) and Photopic (=Sun)
light.
The so-called S/P ratio plays an important factor.
For strict roadlighting guidelines, Ellipz Lighting has also developed a hybrid
version/photopic (SL3) with a lower S/P ratio, but still 25% better than average
competition.
