This document discusses different types of lighting, including natural lighting and artificial lighting. It describes general lighting, task lighting, and accent lighting. General lighting provides overall illumination for an area and can be accomplished through ceiling fixtures, wall mounts, and floor or table lamps. Task lighting helps with specific tasks and can come from pendant lights, under cabinet lighting, or portable lamps. Accent lighting is used to spotlight items and adds visual interest through track lights, under cabinet lights, or wall mounts. The document also discusses direct, indirect, diffused, semi-indirect, and semi-direct types of lighting.

 This broad range of fixtures is, as its name implies, mounted directly to the ceiling, and typically
features a glass, fabric, or plastic shade that conceals the lightbulb and helps diffuse light more
evenly.
 Ceiling-mounted fixtures tend to be used to provide ambient light in a room asopposed to

23. Types of lighting
1. Direct
2. Indirect
3. Diffused
4. Semi-Indirect
5. Semi direct

24. DIRECT LIGHTING
This kind of light comes fromthe sources such
as ceiling fixtures or luminous ceiling that shed
light downward, or fromlamps with translucent
shades spreadinglight in all directions

25. INDIRECT LIGHTING
Lightingin which the lightemittedby a source is diffusely
reflected. • It may also come from a lamp with an opaque
shade open only atthe top. • Lightis thenthrown againstthe
ceiling or washes againstthewalland is reflected back into
the room.
• It is softer thandirect lighting,but oftenmore costly in both
installationand operation.

26. DIFFUSED LIGHTING
When lightfittings are completelyenclosed or
concealed,as with some globesand ceilingpanels,
the lightis diffusedsince it passes throughthe glass
or plastic. Diffused lightingis also glare- freeand
producesa flat appearance.

27. SEMI-INDIRECT LIGHTING
It is possible to have some light
passing through a diffusing bowl
and some reflecting off the
ceiling where the fixture is open
on top

28. Semi direct Lighting
 Semi-DirectLighting is thekind
of lightingprovided from a source without
reflection fromother surfaces. In daylighting, this
meansthatthe lighthas travelled on a straight path
from the sunto the point of interest.
