Publication number: 20230184902Abstract: A vehicular light source system includes: first and second laser emitters configured to emit first and second lasers; a thermometer configured to measure peripheral temperature; and a light source controller. The strength of the first laser at a temperature lower than a threshold temperature is higher than that of the second laser at that temperature. The strength of the first laser at a temperature higher than the threshold temperature is lower than that of the second laser at that temperature. The light source controller is configured to control the first and the second laser emitters such that: the strength of the first laser becomes higher than that of the second laser if the peripheral temperature is lower than the threshold temperature; and the strength of the second laser becomes higher than that of the first laser if the peripheral temperature is higher than or equal to the threshold temperature.Type: ApplicationFiled: April 30, 2021Publication date: June 15, 2023Applicant: KOITO MANUFACTURING CO., LTD.Inventors: Yukihiro ONODA, Hidemichi SONE

Patent number: 10627063Abstract: A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.Type: GrantFiled: May 11, 2018Date of Patent: April 21, 2020Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Yuzo Maeno, Tsukasa Tokida, Shinpei Maeda, Hidemichi Sone

Patent number: 10378717Abstract: An optical unit includes a rotary reflector rotating in one direction around its rotation axis while reflecting light emitted from a light source. The rotary reflector is provided with a plurality of reflecting surfaces such that light of the light source reflected by the rotary reflector rotating is configured to form a desired light distribution pattern. Each of the reflecting surfaces includes a first reflecting surface configured to form a first partial region of the light distribution pattern, and a second reflecting surface configured to form a second partial region of the light distribution pattern different from the first partial region.Type: GrantFiled: October 20, 2017Date of Patent: August 13, 2019Assignee: KOITO MANUFACTURING CO., LTD.Inventor: Hidemichi Sone
