-
Lighting Art: 3D
- front light 30-40 degrees
- light a surface behind
-
Lighting Art: Flat
- o Uniform vs. Non Uniform
- o 30 degree angle best
- Minimizes shadow
- Minimizes reflection
- No shadow from viewer
-
Lighting Art: Conservation
- o Limit UV and Visible radiation
- o Limiting light and heat
- § Evaluate daylight exposure
- White paint is good
- § Evaluate electric light exposure
- filter
- May need UV filter
- Lower footcandles
- § Evaluate duration of exposure
- Remember warmer light is better at lower levels
- Reduce the level and length for success
-
SC:
spacing criterion, is the center to center distance between luminaries (provided by manufacturer)
-
MH:
mounting height calculated by subtracting 30” from the room height or source of light as in the case of a pendant fixture.
-
S=MH X SC
- o If a room has 10’ ceilings with recessed fixtures that are used as general ambient lighting how far apart the fixtures should be mounted to create even light levels around the room.
- Wall height=10’
- Mounting height= 7-6” (10’-2’6”)
- Spacing Criterion= 1.5 (provided by the specs)
- Space apart= MH (7.5) x SC (1.5) = 11’-3” (11.25)
-
Individual unit, point source wall wash
- o When spacing fixtures out from the wall, they should be placed parallel to wall and placed parallel to wall and places aprox. 1/3 the height of the wall
- § Ex: If the wall is 10’ high the fixtures would be placed aprox. 3’ out
- o Square rule is used for spacing fixtures side to side: centers of fixtures should be closer than or equal to distance from wall (see above) (remember Mrs. Cox’s drawing on white board)
- § Ex: The fixture place at 3’ from
- wall should be space no more than 3’ from each other.
-
Continuous, linear, point source wall wash
- o Spacing is similar to individual unit
- o Mock ups are the best test
-
Continuous, linear, diffuse source wall wash
- o Fluorescent tube lamps work well but not uniform along the full height of the wall
- o Use only on walls from 8’-10’ tall
