Patent number: 11906123Abstract: A light source module is switchable between a high beam and a low beam, and is mounted on a vehicle. A first light source is arranged such that its output light is irradiated to a low-beam region by a first optical system. A second light source is arranged such that its output light is irradiated to a high-beam region by a second optical system. A lighting circuit supplies a driving current to the first light source in response to a turn-on instruction for either the high beam or the low beam. Furthermore, the lighting circuit supplies the output current to the second light source in response to a turn-on instruction for the high beam.Type: GrantFiled: January 31, 2022Date of Patent: February 20, 2024Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Tomoyuki Ichikawa, Norikazu Saito, Atsushi Ozawa

Patent number: 7934752Abstract: An image forming method is provided to attain a higher security for preventing forgery and falsification of information by using an optical diffraction structure. In a body (10) whereupon a layer is to be transferred, printing information (2) is recorded. On the body (10), a layer (20d) including a hologram and a diffraction lattice provided on an optical diffraction structure transfer sheet (20) is transferred, and an image including recorded printing information (2) and optical diffraction structures (3, 4, 5) is formed. The layer (20d) including the optical diffraction structure is transferred so that the diffraction lattice (5) to be transferred forms diffraction lattice information (5) showing a prescribed regularity in a corresponding relationship between the printing information (2).Type: GrantFiled: March 8, 2004Date of Patent: May 3, 2011Assignee: Dai Nippon Printing Co., Ltd.Inventors: Norikazu Saito, Fumihiko Mizukami, Makoto Aoyagi, Tetsuya Matsuyama, Hiroshi Funada, Tadahiro Ishida

Patent number: 5406464Abstract: A reflector for a vehicular headlamp in which glare formed by light reflected from a stepped part at the boundary of the adjacent segments constituting a reflector is reduced. Of the distribution control segmental areas on the reflecting surface, a first reflecting area consisting of an aggregation of hyperbolic paraboloid segments forms a pattern widely diffused in the horizontal direction. Second reflecting areas each consisting of elliptic paraboloid segments form a pattern contributing to the formation of the luminous-intensity center of a distribution pattern. A third reflecting area consisting of an aggregation of paraboloid-of-revolution segments forms a pattern contributing to the formation of a cut line tilted a given angle with respect to the horizontal line in the distribution pattern of a passing beam. The focal distance of the reference surface for the paraboloid-of-revolution surface changes for each segment.Type: GrantFiled: November 12, 1993Date of Patent: April 11, 1995Assignee: Koito Manufacturing Co., Ltd.Inventor: Norikazu Saito
