Patent number: 9989210Abstract: A modularized headlight has a heat sink base, a lens assembly on a front end of the heat sink base, a first illuminating module and a first reflector on a first stage of the heat sink base, a second illuminating module and a second reflector on a second stage of the heat sink base, and a shading component on the first stage. When the first illuminating module is emitting light, the light beams are reflected by the first reflector toward the lens assembly through the shading component to provide a low beam mode. When the second illuminating module is emitting light, the light beams are reflected by the second reflector toward the lens assembly to provide a high beam mode. The modularized headlight is switched between the two modes without mechanical mechanism so that components of the modularized headlight may not be worn out and durability is improved.Type: GrantFiled: May 3, 2017Date of Patent: June 5, 2018Assignee: Yujing Technology Co., Ltd.Inventor: Cheng Feng Huang

Patent number: 9915407Abstract: Disclosed is a vehicular lamp including: a lamp outer case including a lamp housing having an opening and a cover configured to close the opening; a first board mounted with a first light source package; a second board mounted with a second light source package; and an optical member mounted with the first board and the second board. The first board and the second board are different kinds of boards that have different heat dissipation performances. Since the heat dissipation property for the heat generated when the first light source package is driven and the heat dissipation property of the heat generated when the second light source package is driven becomes different from each other, the heat dissipation performances may be properly controlled depending on an irradiation state.Type: GrantFiled: September 20, 2016Date of Patent: March 13, 2018Assignee: Koito Manufacturing Co., Ltd.Inventors: Hiroki Shibata, Akira Saijo, Hiromichi Akimoto

Method and a device for the reduction of margins of the light image of a headlight and the headlight
Patent number: 9854646Abstract: A method and a device for the reduction of margins of the light image of a headline, and the headline incorporating the device, is provided, having a reflective diaphragm which is adapted to be shifted in a light axis direction within adjustment limits of a longitudinal position. The margins of the light image can be detected by an optical colour-sensitive photometric sensor, and colour characteristics of the light image margins can be evaluated by identifying a current position of the reflective diaphragm. The reflective diaphragm can then be fixed in the longitudinal position corresponding to selected colour characteristics of the light image margins. The reflective diaphragm can also be adapted to be shifted in a direction perpendicular to the light axis direction.Type: GrantFiled: March 29, 2016Date of Patent: December 26, 2017Assignee: VARROC LIGHTING SYSTEMS, S.R.O.Inventor: Tomas Kreml -
Patent number: 9822947Abstract: A lens member in front of a light source can include: an incident portion dividing the entering light rays into first light rays obliquely upward and forward and second light rays obliquely upward and rearward; a first reflecting surface reflecting the first light rays; a second reflecting surface reflecting the second light rays; a third reflecting surface reflecting the second light rays reflected by the second reflecting surface; a fourth reflecting surface reflecting at least part of the first light rays reflected by the first reflecting surface and the second light rays reflected by the third reflecting surface; and a light exiting surface having a convex lens surface having a rear-side focal point. The fourth reflecting surface extends rearward from the rear-side focal point. A predetermined light distribution pattern is formed by superposing first and second partial light distribution patterns upon each other as a synthetic light distribution pattern.Type: GrantFiled: August 25, 2015Date of Patent: November 21, 2017Assignee: STANLEY ELECTRIC CO., LTD.Inventor: Ryotaro Owada

Patent number: 9714747Abstract: A vehicle lamp includes a projection lens and a first light source. Light emitted from the first light source is irradiated forward through the projection lens. The shade blocks a part of light from the first light source toward the projection lens to form a low beam light distribution pattern. The light emitting unit causes light to be incident onto the projection lens to form a high beam supplementary light distribution pattern. The light emitting unit includes a second light source and a transparent member. Light emitted from the second light source is incident on the transparent member. The transparent member emits the incident light from the front end surface thereof. An emission window is formed in the upper surface of the transparent member and in rear of a front edge of the upper surface. The emission window emits the light incident onto the transparent member, toward the projection lens.Type: GrantFiled: August 10, 2015Date of Patent: July 25, 2017Assignee: KOITO MANUFACTURING CO., LTD.Inventor: Michio Tsukamoto
