发明名称 SEMICONDUCTOR LIGHT SOURCE APPARATUS AND LIGHTING UNIT
摘要 A semiconductor light source apparatus can emit various color lights having a substantially uniform color tone and high brightness. The semiconductor light source apparatus can include a radiating substrate, at least one phosphor layer disposed on the radiating substrate and a semiconductor light source emitting blue light. The at least one phosphor layer can be composed of at least one of a glass phosphor and a phosphor ceramic. The light source can be located adjacent the phosphor layer so that the blue light having high brightness can be efficiently reflected on the radiating substrate via the phosphor layer while preventing the blue light from a mirror reflection on the phosphor layer. Thus, the disclosed subject matter can provide a semiconductor light source apparatus that can emit various uniform color lights having high brightness and a lighting unit using the light source apparatus, which can be used for general lighting, vehicle lighting etc.
