Abstract

To provide a light emitting device that does not experience a decline in radiant efficiency in use, enables luminous flux from LED elements to be increased, and white light of good color rendering to be produced, and heat generated by the LED elements to be smoothly transmitted to an SiC fluorescent substrate. The light emitting device is provided with first LED elements for emitting UV radiation, second LED elements for emitting visible light, an SiC fluorescent substrate that is mounted with the first LED elements and the second LED elements and is made of SiC 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, and has a body made of inorganic material.
