发明名称 LIGHT EMITTING DEVICE
摘要 A light emitting device includes a first light source, an optical waveguide body, a light emitting layer and a first reflection layer. The optical waveguide body includes a first end surface to which light from the first light source is injected, and a second end surface opposed to the first end surface and provided in a light guiding direction of the light. The light emitting layer includes, along the light guiding direction, phosphor particles capable of absorbing the light and emitting wavelength converted light or a light diffusing agent diffusing the light. The first reflection layer is provided on the second end surface and is capable of reflecting part of the light guided in the optical waveguide body. Diffused light from the light emitting layer is emitted to outside of the optical waveguide body.
