Patent ID: 8134166

Claim:
A light emitting device comprising: first LED elements for emitting UV light; second LED elements for emitting visible light; a substrate on which said first LED elements and said second LED elements are carried and which is made of inorganic material; a cage body which houses said first LED elements, said second LED elements and said substrate and which is made of an inorganic material; and a flat plate-shaped SiC fluorescent screen which is doped with at least one of B and Al and with N and which emits visible light when it is excited by the light emitted from said first LED elements, wherein said SiC fluorescent screen is arranged at a distance from said first LED elements and said second LED elements, and wherein said SiC fluorescent screen has a periodic structure, on a surface at which the light emitted from the first LED elements is incident, which is formed of a period that is smaller than the emission wavelength of the first LED elements.
