    • Lighting devices and/or systems offer dynamic control or tuning of color of light. The lighting systems utilize sources, such as solid state sources, to individually pump a number of different phosphors of types having relatively high degrees of color purity. The phosphor emissions, however, are still broader than the traditionally monochromatic color emissions of LEDs. The different phosphors can be independently excited to controllable levels, by individually controlled sources rated for emission of energy of the same spectrum. Adjustment of intensities of electromagnetic energy emitted by the sources independently adjusts levels of excitations of the phosphors selected to emit different colors of relatively high purity and thus the contributions of pure colors to the combined light output, for example, to enables color adjustment of the light output over a wide range of different selectable colors encompassing much of the gamut of visible light.
    • 照明设备和/或系统提供光的颜色的动态控制或调谐。 照明系统利用诸如固态光源的源来单独泵送具有相对较高色彩纯度的类型的许多不同的荧光体。 然而,荧光体发射仍然比LED的传统单色彩色发射更广泛。 不同的荧光体可以独立激发到可控的水平,通过单个控制的光源来评估相同光谱的能量发射。 由源发射的电磁能量的强度的调整独立地调节被选择发射不同颜色的相对高纯度的磷光体的激发水平,并因此调节纯色对组合光输出的贡献,例如能够使光的颜色调节 输出范围广泛的不同的可选颜色,涵盖大部分可见光范围。
