Document Type and Number:
WIPO Patent Application WO/2016/147759
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a high-safety fluorescent light source device with which excitation light can be kept from being directly emitted to the outside. The fluorescent light source device of the present invention is equipped with an excitation light source for emitting laser light, a fluorescent body that emits fluorescence upon being excited by laser light from the excitation light source, and a light emission window via which the fluorescence emitted by the fluorescent body is emitted to the outside; wherein the light emission window is configured from a fluorescence-transmitting light emission window member comprising a material that does not transmit excitation light, and the light emission window is provided with a damage detection sensor for detecting damage to the light emission window member.
