Lighting or illumination is the deliberate use of light to achieve a
practical or aesthetic effect.
Lighting includes the use of artificial light sources like lamps and
other light fixtures.
Proper lighting can enhance task performance, improve the
appearance of an area, or have positive Psychological Effects on
Indoor lighting is usually accomplished using light fixtures, and is a
key part of interior design.
Lighting can also be an essential component of landscape projects.
If your room faces NORTH: you won't get much direct sunlight but a
cold, harsh light. Artists choose to have their studios facing north as you
get a truer colour rendition.
If your room faces EAST: you'll have bright light first thing in the
morning, with long shadows and will lose the sun later in the day.
If your room faces SOUTH: you'll have a warm light all day, although it
changes throughout the day and year. The midday sun will tend to be so
bright it will flatten everything out.
If your room faces WEST: you'll get sunlight at the hottest part of the
day, which can cause glare. Then in the late afternoon you'll get long
shadows and a softer light.
POINTS TO BE REMEMBERED
North and East facing rooms - need to
maximise the quality of light and may need
artificial lighting and measures to control glare.
South and West facing rooms - generally
receive lots of light, which needs controlling.
TYPES OF LIGHTING
Lighting is classified as general, accent, or task lighting, depending
largely on the distribution of the light produced by the fixture.
• Task lighting is mainly functional and is usually the most
concentrated, used for purposes such as reading or inspection of
Mostly found in residential and commercial settings. They may have special
features allowing it to be repositioned or adjusted for reading or other tasks,
or to create a particular lighting ambiance, as in the corner of a living room.
A folding tripod base facilitates storage or repositioning, while an adjustable
arm can be used to direct the light onto seating or working areas.
Stainless steel, aluminium, cast iron and other materials are used to make
these lamps. Base forms include tripod or pedestal styles.
Starts from Rs.800 and the price goes high according to the design.
• Accent lighting is mainly decorative, intended to
highlight pictures, plants, or other elements of interior
design or landscaping.
• Several EMTEQ LED lighting products can function as accent lighting in
your aircraft, including LED flexible strip lighting, LED curved wash
lighting, LED spot lighting and LED vanity lighting.
• Accent lighting is designed to be robust and functional yet attractive and
as inconspicuous or noticeable as desired.
• Accent lighting can be installed around seat bases, toe kicks, vanities and
dropped aisles, among many other areas in the aircraft.
• Products are economical and are perfect for installation.
• Price starts from Rs.1000.
• General lighting or ambient light 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 may be as low as 10-20 lux since pedestrians and motorists already
used to the dark will need little light for crossing the area.
Luminus has developed the XNOVA line of LEDs for professional and general
lighting to enable further adoption of solid-state lighting by providing
customers with outstanding technical performance and superior value.
The XNOVA product line consists of a family of chip-on-board (COB) arrays
and emitter products designed to provide best in class LED sources for
applications including professional lighting fixtures and replacement lamps.
Exceptional efficacy, colour quality and reliability are hallmarks of XNOVA
technology with performance leading today’s top-tier LED suppliers.
• Technologies and Price usually starts from Rs.3000 and the next depends
on designs of lights and material used but they are economical.
• Cove lighting is a form of indirect lighting built into ledges, recesses, or
valences in a ceiling or high on the walls of a room. It directs light up
towards the ceiling and down adjacent walls.
• It may be used as primary lighting, or for aesthetic accent, especially to
highlight decorative ceilings.
• Cove lighting is valued because it hides the fixtures, and because it
provides a very even, warm light.
One method of installing cove lighting is by using T5 fluorescent tubes. T5
luminaires are an energy-efficient alternative as they save on materials.
An even better energy-efficient alternative is to use LED strips, mounted on
an aluminium profiles for optimum heat dissipation, with prismatic covers.
With a dimming controller, the cove lighting can be dimmed. A wide range of
LEDs are available.
Lighting specialists recommend installing cove lighting at least 18 inches from the
ceiling and 6 feet 8 inches from the floor.
In kitchens, cove lights can be installed on the top of kitchen cabinets.
A chandelier is a decorative ceiling-mounted light fixture.
Chandeliers are often ornate, and normally use lamps hung from the ceiling.
Crystal chandeliers have more or less complex arrays of crystal prisms to
illuminate a room with refracted light.

UNDERWATER ACCENT LIGHTS
Underwater Accent Lighting is also used for koi ponds, fountains, swimming
pools and the like.
A lamp is a replaceable component which is designed to
produce light from electricity. These components usually have a base
of ceramic, metal, glass or plastic, which makes an electrical
connection in the socket of a light fixture. This connection may be
made with a screw-thread base, two metal pins, two metal caps or a
Lamp types include:
Light emitting diodes(LED)
Compact fluorescent lamps
A light-emitting diode (LED) is a semiconductor light source.
LEDs are used as indicator lamps in many devices and are increasingly used
for general lighting.
Appearing as practical electronic components in 1962, early LEDs emitted
low-intensity red light, but modern versions are available across
the visible, ultraviolet, and infrared wavelengths, with very high brightness.
ECONOMICAL AND DURABLE
A compact fluorescent lamp (CFL), also called compact fluorescent
light, energy-saving light, and compact fluorescent tube, is a fluorescent
lamp designed to replace an incandescent lamp, some types fit into light
fixtures formerly used for incandescent lamps.
The lamps use a tube which is curved or folded to fit into the space of an
incandescent bulb, and a compact electronic ballast in the base of the lamp.

Dimmers are devices used to vary the brightness of a light. By decreasing or
increasing the RMS voltage and, hence, the mean power to the lamp, it is
possible to vary the intensity of the light output. Although variable-voltage
devices are used for various purposes, the term dimmer is generally reserved
for those intended to control light output
from resistive incandescent, halogen, and (more recently) compact
fluorescent lights (CFLs) and light-emitting diodes (LEDs). More specialized
equipment is needed to dim fluorescent, mercury vapor, solid state and
other arc lighting.
DIMMERS USUALLY CATCH THE ELECTRICITY VOLTAGE WITH THE
HELP OF AN INCREASE AND DECREASE OF LIGHT WITH A REMOTE
CONTROL OR A BUTTON.
NOT VERY EXPENSIVE BUT SOMETIMES COSTLY ACCORDING TO
Floodlights can be used to illuminate outdoor playing fields or work zones
during night-time hours. The most common type of floodlights are metal
halide and high pressure sodium lights.
Light tubes or light pipes are physical structures used for transporting or
distributing natural or artificial light for the purpose of illumination, and are
examples of optical waveguides.
Light pipes may be divided into two broad categories:
Hollow structures that contain the light with a reflective lining, and
Transparent solids that contain the light by total internal reflection.
Generally speaking, a light pipe or light tube may refer to:
A tube or pipe for transport of light to another location, minimizing the loss
of light, a transparent tube or pipe for distribution of light over its length,
either for equidistribution along the entire length or for controlled light
