    • Color management and color-managed workflow concepts are applied to lighting apparatus configured to generate multi-colored light, including lighting apparatus based on LED sources. In particular, color management principles are employed to facilitate the generation of variable color light from a given lighting apparatus based on any of a number of possible input specifications for a desired color. In one example, a transformation between an arbitrary input specification for a desired color and a lighting command processed by the lighting apparatus is accomplished via the use of a source color management profile for the input specification of the desired color, a target color management profile for the lighting apparatus, and a common working color space. Colors defined in the common working color space may be reproduced or approximated (e.g., according to one or more rendering intents) by one or more lighting apparatus.
    • 颜色管理和颜色管理的工作流概念被应用于被配置为生成多色光的照明装置,包括基于LED源的照明装置。 特别地,采用颜色管理原理,以便根据所需颜色的多种可能的输入规格中的任何一种来促进来自给定照明装置的可变色光的产生。 在一个示例中,通过使用用于所需颜色的输入规格的源颜色管理简档来实现期望颜色的任意输入规格与由照明装置处理的点亮命令之间的变换,用于 照明装置和公共工作色彩空间。 可以通过一个或多个照明装置再现或近似(例如,根据一个或多个渲染意图)在公共工作颜色空间中定义的颜色。

    • 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。

    • Methods and apparatus for generating two or more different colors or color temperatures of light over a significant range of different saturations or different color temperatures, in which luminance compensation is provided. In one example, generated light is compensated, at least in part, for the "Helmholtz-Kohlrausch" (HK) effect, which models the perception of different brightnesses for different colors or color temperatures, notwithstanding identical luminances. In another example, lighting apparatus including one or more LEDs to generate two or more different colors or color temperatures of light are configured to provide luminance compensation so as to mitigate, at least in part, the HK effect.
    • 用于在提供亮度补偿的不同饱和度或不同色温的显着范围内产生两种或更多种不同颜色或色温的方法和装置。 在一个示例中,生成的光至少部分地被补偿为“亥姆霍兹 - 科尔劳兴”(HK)效应,其对不同颜色或色温的不同亮度的感知进行建模,尽管具有相同的亮度。 在另一示例中,包括一个或多个LED以产生光的两种或更多种不同颜色或色温的照明装置被配置为提供亮度补偿,以便至少部分地减轻HK效应。
