    • Methods and apparatus for controlled lighting based on a reference color gamut that is shared amongst multiple lighting units. A reference color gamut may be determined for multiple lighting units based on spectral power distributions associated with the lighting units. Variable color light or variable color temperature white light subsequently may be generated consistently and predictably amongst multiple lighting units that are each controlled based on the reference color gamut. Lighting commands received by multiple lighting units may be appropriately processed in each lighting unit, based on a predetermined relationship between the lighting commands and the reference color gamut, to ensure consistent and predictable color or color temperature reproduction amongst the multiple units. In one exemplary implementation, the multiple lighting units include LED light sources to facilitate energy efficient generation and versatile control of variable color light or variable color temperature white light, for general purpose illumination and other applications.
    • 基于参考色域的受控照明的方法和装置,其在多个照明单元之间共享。 可以基于与照明单元相关联的光谱功率分布来为多个照明单元确定参考色域。 随后可以在各自基于参考色域控制的多个照明单元中一致地且可预测地产生可变色光或可变色温白光。 基于照明命令和参考色域之间的预定关系,可以在每个照明单元中适当地处理由多个照明单元接收的照明命令,以确保多个单元之间的一致和可预测的颜色或色温再现。 在一个示例性实施例中,多个照明单元包括用于促进能量效率生成的LED光源以及可变色光或可变色温白光的通用控制,用于通用照明和其它应用。
