Fluorescent
material by the light stimulation, which stimulated the energy of
electronic excitation state of order, go back to the original state of
low-energy bands, the energy in the form of light radiation out of the
so-called "photoluminescence." Different fluorescent light excited by
the ceramic powder, the issue of the different colors of light,
research and development these new and high-efficiency fluorescent
powder, LED is one of the goals of development.
