Abstract
A reliable reflective typed semiconductor light source apparatus can emit various color lights having high brightness. The apparatus can include a first and second reflector layer, a phosphor plate disposed on the first reflector layer and a semiconductor light source. The phosphor plate can include at least one of at least one of a red phosphor, a green phosphor, a blue phosphor and a yellow phosphor. The light source can be located adjacent the phosphor plate so that an excited light emitted from the light source can be efficiently reflected on the first reflector layer via the phosphor plate and so that heats generated from the first reflector layer and the like can efficiently transmit toward the second reflector layer. Thus, the disclosed subject matter can provide a semiconductor light source apparatus that can emit various color lights having high brightness, and which can be used for general lighting, etc.
