| Patent Number: |
8152332 |
| Title: |
LED Cyclorama Light |
| Abstract: |
A cyclorama light includes a generally enclosed housing forming an
interior compartment having a normally horizontal housing axis and an
open front defining a window generally arranged within a plane parallel
to said axis. A reflector substantially covers the window and has an
operative portion that has a substantially uniform cross-section along
the housing axis. An LED light emitter array extends along a line
substantially parallel to the housing axis, the reflector having a
surface configuration and the LED array being arranged in relation to the
reflector surface to provide a higher flux density directed toward a far
end of a wall or surface to be illuminated and provide a lower flux
density directed toward a direction of the near end of the surface to be
illuminated, generating a transition flux density between the far and
near ends of the surface to be illuminated. The LED array and/or the
reflector have optical features for eliminating shadows in the projected
light over the entire illuminated surface.
