Document Type and Number:
WIPO Patent Application WO/2023/276659
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an automatic analysis device and a light source that covers a wide wavelength range used by the automatic analysis device and produces a stable amount of light. A light source according to this invention comprises a substrate, a first LED that is provided on the substrate, and a fluorescent body that converts excitation light from the first LED into broadband light. A temperature sensor is embedded in the fluorescent body together with the first LED. Further, an automatic analysis device according to this invention comprises an absorbance measurement unit having the light source and a reaction disk having mounted thereon a reaction vessel accommodating a reaction liquid to be measured by the absorbance measurement unit.
