Device and method for emitting output light using group IIA/IIB selenide sulfur-based phosphor material

摘要

A device and method for emitting output light utilizes Group IIA/IIB element Selenide Sulfur-based phosphor material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the optical spectrum of the output light. Thus, the device and method can be used to produce white color light. The device and method may also utilize Thiogallate-based phosphor material.
