| Title: |
Power Allocation Methods For Lighting Devices Having Multiple Source Spectrums, and Apparatus Employing Same |
| Abstract: |
Methods for allocating power amongst different source spectrums, or
"channels," of a multi-channel lighting unit, and apparatus that employ
such methods. Power allocation methods exploit the total light-generating
capability of a lighting unit while maintaining safe operating power
conditions, so as to avoid damage to the lighting unit due to excessive
thermal power generation. In one example, a power allocation method
ensures that a lighting unit operates at or near its maximum power
handling capability for a variety of possible high brightness lighting
conditions by ascribing a maximum per channel operating power equal to
the maximum power handling capability of the lighting unit. The power
allocation method then reapportions, if necessary, prescribed operating
powers for multiple channels, in response to a given lighting command,
such that the ratio of the prescribed powers remains the same but the sum
of the channel operating powers does not exceed the maximum power
handling capability of the lighting unit.
