Patent number: 7722235Abstract: A vehicle headlamp is provided. The vehicle headlamp includes a projection-type light source unit housed in a lamp chamber. The light source unit includes a projection lens; a shade; a light emitting diode (LED) light source; a reflector; and an optical element. The LED light source includes a substrate; an LED chip disposed on the substrate such that the LED chip is oriented in a direction substantially perpendicular to an optical axis of the light source unit; and a cover member. A region of the cover member includes concave and convex portions so as to diffuse light transmitted through the cover member. The reflector reflects and guides the light from the LED light source onto a rear focus of the projection lens. The optical element guides the diffused light transmitted through the cover toward a front side of the vehicle headlamp so as to form an overhead light distribution.Type: GrantFiled: October 27, 2008Date of Patent: May 25, 2010Assignee: Koito Manufacturing Co., Ltd.Inventors: Kazuhisa Mochizuki, Nobutaka Tezuka

Patent number: 7535406Abstract: A vehicular lamp 1 including a lamp unit 13 provided inside a lamp chamber 7 so that the optical axis direction of lamp unit 13 is adjustable with the use of a tilting movement adjustment mechanism 15. The lamp chamber 7 is formed by a lamp body 3 and a transparent front cover 5 attached to the front opening of the lamp body 3, while the lamp unit 13 is formed by a reflector 9 and a light source 11. A millimeter wave radar device 25 is installed in the vehicular lamp, and it is composed of a controlling unit 25B and an antenna unit 25A that are provided separately from each other so that the controlling unit is attached to the lamp body and the antenna unit is attached to the lamp unit.Type: GrantFiled: December 14, 2007Date of Patent: May 19, 2009Assignee: Koito Manufacturing Co., Ltd.Inventors: Yasuo Teranishi, Nobutaka Tezuka, Toshinao Daicho, Takashi Hori

Publication number: 20060002126Abstract: A vehicular lamp including partitions 11 and 12, 13 that demarcate the interior of a lamp chamber 3 defined by a lamp body 1 and an outer lens 2 into a plurality of regions 31 to 33, a light source 62a disposed in at least one of the regions, an inner lens 5 provided to cover the partitions, a means for guiding a part of the light emitted from the light source 62a into the inner lens 5. In addition to one region demarcated by the partitions is brought into a lit state by light directly emitted from the light source 62a, the inner lens 5 is lit by the light from the light source 62a that is guided into and radiates from the inner lens surface.Type: ApplicationFiled: June 14, 2005Publication date: January 5, 2006Inventors: Hiroya Koizumi, Nobutaka Tezuka, Hajime Takeda, Hidenori Suzuki

Patent number: 6382822Abstract: A vehicular lamp having an inner lens is described. In an implementation, an annular wall 18A surrounding an optic axis Ax of a reflector 14 is formed on the inner lens 18 disposed between am outer lens 16 and a reflecting surface 14a of the reflector 14. The inner lens 18 is divided by the annular wall 18A into an internal zone 18B and an external zone 18C which may be different from each other in convex-concave lens shape. The internal zone 18B may be formed of a translucent lens, and a plurality of grid-type lens elements 18Cs may be formed over the entire rear surface of the external zone 18C. Thus, an observer viewing the interior of a lighting chamber from a location in front of the lamp will see that the internal zone 18B and the external zone 18C, which are divided by the annular wall 18A, are significantly different. The configuration of elements provides a vehicular lamp that is visually attractive.Type: GrantFiled: May 3, 2000Date of Patent: May 7, 2002Assignee: Koito Manufacturing Co., Ltd.Inventors: Gen Maekawa, Nobutaka Tezuka
