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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phosphor-centric control of color of light","description":"Lighting devices and/or systems offer dynamic control or tuning of color of light.
