White light source manufacturing method, involves preparing three phosphors to receive ultra-violet light and emit primary color lights, and another phosphor to modify spectral property of light emitted by three phosphors

摘要

The method involves providing a ultra-violet light serving as a radiation source. Three phosphors are prepared for receiving the ultra-violet light and emitting primary red, green and blue color lights, respectively. Another phosphor is prepared for modifying a spectral property of the light emitted by the three phosphors, where the latter phosphor is optically excitable by the ultra-violet light or a visible light.
