The light emitting surface is interchangeable thereby enabling the source to generate different selected colors of light using the same LED. The phosphor can be provided as a layer on the substrate or incorporated within the light transmissive substrate. The light emitting surface can be configured as a waveguide or as a light transmissive window.

摘要： Disclosed herein are “smart” phosphor compositions capable of regulating the chromaticity of their emission to substantially constant values even with variations in the excitation radiation they receive to induce photoluminescence. One phosphor of the smart composition demonstrates an increase in emission intensity increases as the wavelength of the excitation radiation is increased. The other phosphor shows a decrease in emission intensity with increasing excitation wavelength. Constant chromaticity in this context is defined as a change in CIE x or y coordinate of less than about five percent over a 10 nm range of excitation wavelengths.
