2. • Types
• A demonstration of the effects of different
kinds of lighting
• Lighting is classified by intended use as
general, localized, or task lighting,
depending largely on the distribution of the
light produced by the fixture.
TASK LIGHTING
• Task lighting is mainly functional and is
usually the most concentrated, for purposes
such as reading or inspection of materials.
• Task lighting can simply be described as
light focused on a particular area to facilitate
visual tasks.
• Task lighting is quite different from mood
and area lighting, which are intended to light
different regions or a given space, and at
times create particular desired effects.

3. • Visual tasks will be executed well and
accurately if the working area is well lit.
• Further, task lighting will reduce the strain
on eyes normally experienced in work
environments such as computing.
• This way, the work environment will be
satisfying and pleasant and workers will be
happy and healthy.
• In the kitchens, it ensures that the working
area is well lit so that one can read a
recipe when cooking, for example. Kitchen
lighting in important so just in case you
won’t slice your finger when cutting a
tomato! In dining and living rooms, task
lighting is mostly to be found over the
chairs and tables to make it easy for
people to read or see each other when
conversing.

4. Accent lighting
• Accent lighting is mainly decorative,
intended to highlight pictures, plants, or
other elements of interior design or
landscaping.
• Accent lighting. When located on a
deck or patio, accent lighting can
present a range of advantages.
• Having sufficient accent lighting to
safely walk around at night is vital to
keep away from falls yourself as well
as the items in your yard.
• Many solar accent lighting are used
with security in mind.
• Accent Lighting gives texture, focus and
shape to general lighting, adding depth
and shade, with shadows in some
corners and pools of light in others. It's
formed by a mixture of halogen
spotlights, down-lighters, up-lighters,

5. • • Glass: light from below or behind.
• • Books: clip a spotlight on the underside of the
shelf or put wall washers into the ceiling.
• • Pictures and paintings: it's tricky to light
paintings well - and if they're behind glass there
is an additional problem of glare
• • Plants: For a large pot, put an up-lighter or a
spotlight recessed into the floor behind it. The
light bounces off the floor and the ceiling and
diffuses back into the foliage of the plant to
create unusual shadows..
Accent Fixtures
• Accent fixtures allow light to focus on art and
building surfaces.
• Recessed accent lights appear as downlights
but internally permit rotation and elevation of
the light beam.
• Eyeballs and pulldown accents resemble
downlights, but their appearance belies the
ability to be adjusted.
• Track lighting systems are designed to accent
art and retail displays

6. AMBIENT LIGHTING
• General lighting (sometimes referred to as
ambient light) fills in between the two and
is intended for general illumination of an
area.
• Indoors, this would be a basic lamp on a
table or floor, or a fixture on the ceiling.
Outdoors, general lighting for a parking lot

7. • Ambient lighting is a general illumination
that comes from all directions in a room
that has no visible source.
• This type of lighting is in contrast to
directional lighting.

8. • Methods
• Downlighting is
most common, with fixtures
on or recessed in the
ceiling casting light
downward.
• This tends to be the most
used method, used in both
offices and homes.
• Although it is easy to
design it has dramatic
problems with glare and
excess energy
consumption due to large
number of fittings.[

9. • Uplighting is less common,
often used to bounce indirect light
off the ceiling and back down.
• It is commonly used in lighting
applications that require minimal
glare and uniform general
illuminance levels.
• Uplighting (indirect) uses a
diffuse surface to reflect light in a
space
• It gives a more uniform
presentation of the light output in
operation.
• However indirect lighting is
completely reliant upon the
reflectance value of the surface.
• While indirect lighting can create
a diffused and shadow free light
effect it can be regarded as an
uneconomical lighting principle

10. • Track lighting, invented by
Lightolier, was popular at one point
because it was much easier to
install than recessed lighting, and
individual fixtures are decorative
and can be easily aimed at a wall.
• It has regained some popularity
recently in low-voltage tracks
• A master transformer feeds all of
the fixtures on the track or rod with
12 or 24 volts, instead of each light
fixture having its own line-to-low
voltage transformer.
• There are traditional spots and
floods, as well as other small
hanging fixtures.
• A modified version of this is cable
lighting, where lights are hung from
or clipped to bare metal cables
under tension.

11. • Track lighting by definition has its
circuit and mounting elements
exposed and many would sooner
not use them at, single fixture
spotlighting, sconces, and other
fancier decorative lighting fixtures.
For one, track lighting is highly
configurable.
• You can run the tracks in the areas
where light is needed and with
flexible tracks you can bend tracks
in different shapes to the
configuration you need and at the
same time the track can become a
decorative element as well.
• Certain areas of your home are
better suited than others for track
lights, the first one coming to mind
is the kitchen.

12. SCONCE
• A sconce is a wall-mounted
fixture, particularly one that
shines up and sometimes
down as well.

13. Torchiere
• A torchiere is
an uplight
intended for
ambient
lighting.
• It is typically a
floor lamp but
may be wall-
mounted like a
sconce.

14. Table lamp
• The portable or table lamp is probably the
most common fixture, found in many
homes and offices.
• The standard lamp and shade that sits on
a table is general lighting, while the desk
lamp is considered task lighting. Magnifier
lamps are also task lighting.

15. Forms of lighting
• Indoor lighting
• Forms of lighting include alcove lighting, which like most other
uplighting is indirect.
• This is often done with fluorescent lighting (first available at the
1939 World's Fair) or rope light, or occasionally with neon lighting.
It is a form of backlighting.

16. • Soffit
• Soffit or close to wall lighting
can be general or a decorative
wall-wash, sometimes used to
bring out texture (like stucco or
plaster) on a wall, though this
may also show its defects as
well.
• The effect depends heavily on
the exact type of lighting source
used.
• In architectural terms, a soffit is
the underside of any
overhanging structure.
• Outdoors, this can be the area
under roof overhangs or decks.
Indoors, soffit generally refer to a
dropped ceiling around the
edges of the room but also can
mean the area between the top
of kitchen cabinets and the
ceiling, even if it isn't lowered.

17. Recessed lighting
• Recessed lighting (often called "pot
lights" in Canada, "can lights" or
'high hats" in the US) is popular,
with fixtures mounted into the
ceiling structure so as to appear
flush with it.
• These downlights can use narrow
beam spotlights, or wider-angle
floodlights, both of which are bulbs
having their own reflectors.
• There are also downlights with
internal reflectors designed to
accept common 'A' lamps (light
bulbs) which are generally less
costly than reflector lamps.
• Downlights can be incandescent,
fluorescent, HID (high intensity
discharge) or LED.

18. • Recessed lighting brings both general
lighting and task lighting to your home.
• It brings the functional way but also
the decorative one.
• Recessed lightingis often hung over
the wall or ceiling.
• If you need this lighting to shine in
certain area of your home but you are
bored enough with round white lamp,
you can look for the artistic shape of
this lighting.

19. • Cove Lights
• Cove lights permit uplighting from coves or other architectural
elements more
• efficiently than do strip lights, and without socket shadows.

20. Outdoor lighting
• High mast lighting along Highway 401 in
Ontario, Canada.
• Street Lights are used to light roadways and
walkways at night. Some manufacturers are
designing LED and photovoltaic luminaires
to provide an energy-efficient alternative to
traditional street light fixtures.[4][5][6]
• Floodlights are used to illuminate outdoor
playing fields or work zones during
nighttime.
• Floodlights can be used to illuminate
outdoor playing fields or work zones during
nighttime hours. The most common type of
floodlights are metal halide and high
pressure sodium lights.
• Beacon lights are positioned at the
intersection of two roads to aid in navigation.

21. • Security lights can be used along
roadways in urban areas, or behind
homes or commercial facilities. These
are extremely bright lights used to
deter crime. Security lights may include
floodlights.
• Entry lights can be used outside to
illuminate and signal the entrance to a
property.[7] These lights are installed
for safety, security, and for decoration.
• Underwater accent lighting is also used
for koi ponds, fountains, swimming
pools and the like.
