发明名称 Light emitting apparatus and automotive lamp
摘要 A light emitting apparatus includes LED chips and a light condenser condensing the light emitted from the LED chips. The light condenser has a first opening functioning as an incident part through which the light emitted from the LED chips enters, a side surface function as a reflector that reflects the light having entered through the first opening, and a second opening functioning as an emission part that emits the light reflected by the side surface. A phosphor layer, which converts the wavelength of the light emitted from the LED chips and emits the wavelength-converted light, is formed in the first opening. The light condenser is arranged such that the phosphor layer is located on the light emission surfaces of the LED chips.

主权项 1. A light emitting apparatus comprising: a mounting part that mounts a light emitting device thereon; and a light condenser that condenses light emitted from the light emitting device, the light condenser including: an incident part through which the light emitted from the light emitting device enters; a reflector that reflects light entering from the incident part; and an emission part that emits light reflected by the reflector, wherein a phosphor layer, which converts a wavelength of the light emitted from the light emitting device and emits the wavelength-converted light, is formed in the incident part, wherein the light condenser is arranged such that the phosphor layer is located on a light emission surface of the light emitting device, wherein the light condenser includes a molded body made of transparent material having a first surface part, a second surface part disposed counter to the first surface part, and a side surface part disposed in between the first surface part and the second surface part, wherein the first surface part functions as the incident part, the second surface part functions as the emission part, and the reflector is formed such that a metallic film is formed on an outer surface of the side surface part, wherein the phosphor layer is formed by embedding a part of plate-shaped phosphor in the first surface part, wherein the mounting part is arranged such that a plurality of light emitting devices are able to be mounted side by side, wherein the molded body made of transparent material is arranged for each of the plurality of light emitting devices, wherein, in each molded body made of transparent material, an adjacent surface facing the adjacent molded body made of transparent material is formed into flat surface, and wherein, in each molded body made of transparent material, a metallic film is formed on the adjacent surface facing the adjacent molded body made of transparent material as well as the outer surface of the side surface part.
