Patent ID: 8791630

Claim:
A light emitting element, for emitting fluorescence upon receiving a laser beam emitted from an excitation light source, the light emitting element comprising: a plurality of fluorescent material particles made from a single type of fluorescent material or several types of fluorescent materials, the plurality of fluorescent material particles being accumulated on a substrate to form a layer of the plurality of fluorescent material particles, each of the plurality of fluorescent material particles having a surface coated with a coating layer, the coating layer causing the plurality of fluorescent material particles to adhere to each other, the coating layer forming an uneven shape of a surface of the light emitting element, gaps being formed between the plurality of fluorescent material particles each of which has the surface coated with the coating layer, and the laser beam being incident on the uneven surface of the light emitting element so that the florescence is emitted from the uneven surface.
