发明名称 LIGHT EMITTING DEVICE AND METHOD FOR PRODUCING THE LIGHT EMITTING DEVICE
摘要 A light emitting device that has a radiant efficiency that does not decline in use, enables luminous flux to be increased by a high electric current, and produces white light with good color rendering and a method for producing a light emitting device capable of smoothly transmitting heat generated by LED elements to a carrier substrate. The radiation emitting device has first LED elements for emitting UV radiation, second LED elements for emitting visible light, a substrate made of an inorganic material and which carries the first LED elements and the second LED elements, a body made of inorganic material containing the first LED elements, the second LED elements and the substrate, and an SiC fluorescent screen that is doped with at least one of B and Al as well as N and emits visible light when excited by radiation emitted from the first LED elements.
