Color manager for backlight systems operative at multiple current levels |
摘要 |
A color manager for use with a luminaire constituted of a plurality of different colored light emitting diode based sub-luminaires arranged to produce a combined light. The color manager is constituted of a sampler arranged to output an electrical representation of the optical output of the luminaire, a converter coupled to the output of said sampler and operatively associated with a current selector arranged to select the driving current level of the luminaire from a plurality of current levels. The converter is arranged to convert said electrical representation to a pre-determined calorimetric system in cooperation with a calibration matrix whose values are selected responsive to the selected driving current level. The color manager further comprises a driver operatively associated with the luminaire, the converter and current selector and arranged to drive the luminaire in accordance with the driving current level as selected by the selector. |
