Patent number: 11009734Abstract: To reliably perform light irradiation in a vehicular lamp system using a liquid crystal element even in a cryogenic environment. A control device for a vehicular lamp comprising a light source and a liquid crystal element where the liquid crystal element is set to a light-shielded state and the light source is set to a light-on state to heat the liquid crystal element by the light emitted from the light source when the temperature of the liquid crystal element is estimated to be lower than a predetermined value.Type: GrantFiled: August 22, 2019Date of Patent: May 18, 2021Assignee: STANLEY ELECTRIC CO., LTD.Inventors: Yasuo Toko, Yoshihisa Iwamoto, Takuya Kitazono

Patent number: 10788184Abstract: A lighting device for a vehicle includes a light source that illuminates light, a reflecting surface, a shading member, and a projecting lens. The reflecting surface reflects the light illuminated from the light source and causes the light to converge. The shading member includes an aperture portion at which the light reflected and caused to converge by the reflecting surface is incident. Light that has passed through the aperture portion of the shading member is incident on the projecting lens, and the projecting lens emits the light toward a target.Type: GrantFiled: August 29, 2018Date of Patent: September 29, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Fumihiko Mouri, Takuya Kitazono, Norikatsu Myojin
