Document Type and Number:
WIPO Patent Application WO/2017/043121
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the heat dissipation efficiency of a fluorescent body in a transmissive light-emitting device. A light-emitting device (10) is provided with a fluorescent body film (11) that converts the wavelength of excitation light and emits fluorescence, and a light-transmissive substrate (12) that transmits the excitation light. The light-transmissive substrate is provided, in a section of the surface thereof, with the fluorescent body film, and in another section different from the section where the fluorescent body film is disposed, with a heat dissipating part (1) that improves the heat dissipation efficiency of the light-transmissive substrate.
