ABSTRACT:
A light emitting device of the present invention includes an LED substrate and a sealing resin portion which seals the LED substrate, the sealing resin portion having a silicone resin having a refractive index n3to which a fluorescent material having a refractive index n1and fine particles having a refractive index n2are added. In the light emitting device, a relationship of n2>n1>n3holds in the refractive indexes n1to n3, and a particle size of the fine particles is not more than 1/10 of a wavelength of light emitted from the LED substrate.
