摘要:
A light emitting device includes a base on which a wiring conductor is formed from the top surface to the bottom surface or the side face; a light emitting chip mounted on the top surface of the base and electrically connected with the wiring conductor; a first light transmitting member which covers the light emitting chip; a second light transmitting member provided above the first light transmitting member to cover the first light transmitting member, the second light transmitting member being formed of a light transmitting material containing fluorescent materials for converting in wavelength the light emitted from the light emitting chip; and a third light transmitting member provided between the first and second light transmitting members, wherein the refractive index n1 of the first light transmitting member, the refractive index n2 of the second light transmitting member and the refractive index n3 of the third light transmitting member satisfy the relation: n3
