Lighting In an Art Gallery

lighting 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.

Artificial lighting 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

lux 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.

THE IMPORTANT CHARACTERISTICS OF GOOD LIGHTINGS ARE:

lux level required.

CRI OF DIFFERENT TYPES OF LIGHTS

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

TYPES OF LIGHTING SYSTEMS :

the most important lighting systems used in exhibition rooms are:

LUMINOUS CEILINGS

INDIRECT lights

COVE lights

WALLWASHERS

SPOT LAMPS.

LUMINOUS CEILINGS: 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.

INDIRECT LIGHTING:

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.

COVE LIGHTING the curving transition

between wall and ceiling . the cove or coving is another indirect lighting solution.

WALL WASHERS

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.

SPOT LIGHTS three-

dimensional character of an object.

create shadows and to highlight an object's form and texture.

silhouetting.
