Lighting is an important consideration in art galleries as it can impact the longevity of artworks. Daylight is most desirable but artificial lighting is also needed. The key qualities of artificial lighting that can be controlled include availability, angle, intensity, distribution, color, and movement. Different types of lighting fixtures, such as luminous ceilings, cove lights, and spot lamps are suitable for different purposes like providing even illumination or drawing attention to specific artworks. Lighting levels and color rendering properties should be chosen to properly display and preserve the art.

2.  in an art gallery space, daylight and artificial
light are important.
 light fundamentally affects materials through
photo-chemical action and radiant heating
effects from uv & ir rays.
 exposure of sensitive materials to light,
especially daylight, detriments the longevity and
preservation of those artworks or artefacts.

4.  daylight is the most desirable source of light, due to the nature and heating
effect of it the role of artificial lighting becomes larger in art galleries.
 CONTROLLABLE QUALITIES OF ARTIFICIAL LIGHTING ARE
 1.AVAILABLILITY
 2.ANGLE
 3.INTENSITY
 4.DISTRIBUTION
 5.COLOR
 6.MOVEMENT

5.  Lux is the measured light
taken at 1metre above the
ground in the area of interest.
 It helps people determined the
best places to put lighting and
also the amount of lights.

7.  colour rendering
index(cri) of lighting
fixture.
 lux level required.
 dimming

8. INCANDESCENTS
 bring out the warm colors within the
colour spectrum such as the red,
brown, orange, and yellow tones.
FLUORESCENT
 lights aren't used as a common
practice because they give off a high
amount of uv rays which are harmful.
 but can emit light across the entire
spectrum of colours.
HALOGEN :
 a strong white light.
 a very good cri value.
 but emits a lot of heat

9. the most important lighting systems
used in exhibition rooms are:
 LUMINOUS CEILINGS
 INDIRECT lights
 COVE lights
 WALLWASHERS
 SPOT LAMPS.

10.  the idea is to emulate the sky for this kind of
lighting system.
 luminous ceilings deliver light which is
particularly suitable for painting galleries and
give it an opal colour.

11.  indirect lighting adds
brightness to the arts
without creating any
direct or indirect glare.
 light bounced off the
ceiling and upper wall
surfaces into the room.

12.  the curving transition between
wall and ceiling . the cove or
coving is another indirect
lighting solution.

13.  wall washers bring
attention to the wall that
contain the arts and
artefact.
 brings drama & focus to
the object.
 wall washing provides an
even spread of
illumination.
 effect of flattening out
textured surfaces.

14.  three-dimensional
character of an
object.
 create shadows
and to highlight an
object's form and
texture.
 silhouetting.
