LIGHT-EMITTING APPARATUS INCLUDING PHOTOLUMINESCENT LAYER
Abstract:
A light-emitting apparatus includes; a light-emitting device including a photoluminescent layer that receives excitation light and emits light including first light having a wavelength λa in air, and a light-transmissive layer located on or near the photoluminescent layer; and an optical fiber that receives the light from the photoluminescent layer at one end of the optical fiber and emits the received light from the other end thereof. A surface structure is defined on at least one of the photoluminescent layer and the light-transmissive layer, and the surface structure has projections or recesses or both and limits a directional angle of the first light having the wavelength λa in air.
