Title:
HEAT RADIATING LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/079976
Kind Code:
A1
Abstract:
Provided is a heat radiating light source that can be installed in a state where a substrate and a heat radiation layer are exposed to the atmosphere and that indicates a large thermal emissivity in a narrow-band wavelength of 4 µm or less and indicates a small thermal emissivity in a wavelength larger than 4 µm. A heat radiation layer N and a substrate K for heating the heat radiation layer N are laminated. The heat radiation layer N is constructed in a state where a radiation control part Na, provided with a MIM laminate M in which a resonance transparent oxide layer R formed by a transparent oxide is positioned between platinum layers P arrayed along the lamination direction, and a radiation transparent oxide layer Nb, formed by a transparent oxide, are laminated such that the radiation control part Na and the radiation transparent oxide layer Nb are disposed closer to the substrate K in this order. The thickness of the resonance transparent oxide layer R is set such that a wavelength of 4 µm or smaller becomes the resonance wavelength.
