Patent number: 10406725Abstract: Provided is a light source apparatus for resin curing capable of hardening even conventional UV curing resin by irradiating ray in a short time without producing any tackiness on the resin surface, and capable of irradiating a ray for efficiently hardening not only a UV curing resin but also an IR curing resin. The light source apparatus includes a light source, an optical system for guiding a light emitted from the light source to an emission section, and a light transmission section, selectively insertable in a light path in the optical system, for passing there through a UV-C ultraviolet ray containing a ray in the wavelength range of 250 nm, a visible light except for light in the wavelength range from 500 nm to 640 nm and an infrared ray together so as to remove a tackiness on a resin surface.Type: GrantFiled: August 15, 2016Date of Patent: September 10, 2019Assignees: HOLONIX INTERNATIONAL CO., LTD., YAMASHITA DENSO CORPORATIONInventors: Kuniaki Takahashi, Nobuhiko Kubo

Patent number: 10113713Abstract: A light irradiation apparatus includes a plurality of light sources, a plurality of light transmission paths capable of selectively transmitting lights from the plurality of light sources, respectively, and an optical fiber path provided with a plurality of light incidence ends receiving respective lights from the plurality of light transmission paths, and a single light exit end. The optical fiber path has a plurality of optical fiber bundles. Incidence ends of the plurality of optical fiber bundles configures the plurality of light incidence ends, and exit ends of the plurality of optical fiber bundles configure the single light exit end by combining themselves. A lot of optical fibers constitute the plurality of optical fiber bundles. The optical fibers of the plurality of optical fiber bundles are dispersedly arranged with each other in uniform at the single light exit end.Type: GrantFiled: May 17, 2017Date of Patent: October 30, 2018Assignees: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, YAMASHITA DENSO CORPORATIONInventors: Sanekazu Igari, Nobuhiko Kubo

Patent number: 8646925Abstract: A solar simulator includes a light source, an optical reflection element positioned behind the light source to reflect light emitted from the light source in a form of pseudo parallel light, a low-angle light-diffusion optical element for diffusing the reflected light from the optical reflection element at a low diffusion angle, and a parallel light conversion optical element including a number of air holes arranged in parallel rows and provided with faculties for transmitting incident light parallel to the axis of the air holes to absorb or attenuate nonparallel incident light. The parallel light conversion optical element converts the incident light from the low-angle light-diffusion optical element to parallel light and emits the converted parallel light.Type: GrantFiled: March 14, 2011Date of Patent: February 11, 2014Assignees: Yamashita Denso Corporation, Holonix International Co., Ltd.Inventors: Nobuhiko Kubo, Kuniaki Takahashi
