Title:
LIGHT EMITTING DEVICE AND ILLUMINATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/203977
Kind Code:
A1
Abstract:
A light emitting device (100) is provided with: a semiconductor laser element (1) that outputs laser light; a fluorescent body (5) that emits fluorescence when irradiated with, as excitation light, the laser light outputted from the semiconductor laser element (1); and a spectroscopic element (8), which has an input surface (8a), from which the laser light and the fluorescence are inputted, and which separates the laser light and the fluorescence from each other. The spectroscopic element (8) passes one of the inputted laser light and the inputted fluorescence, and reflects the other, and the input surface (8a) of the spectroscopic element (8) is tilted with respect to at least the input direction of the laser light.
