Patent number: 8093613Abstract: Whereas incandescent light bulbs and other similar light sources known in the related art emit light in all directions, LED lamps can emit light in a single direction, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. In accordance with an embodiment of the presently disclosed subject matter, an LED lamp for a light source of a headlamp can include an LED chip in the vicinity of the focus of a projection means and a shielding member covering a portion of the LED chip in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip is magnified and projected in an illumination direction by a projection lens or the like constituting the projection means. Accordingly, accurate light distribution characteristics can be obtained in a simple manner by projecting in the illumination direction using the projection lens.Type: GrantFiled: November 23, 2009Date of Patent: January 10, 2012Assignee: Stanley Electric Co., Ltd.Inventors: Yasushi Yatsuda, Takashi Ebisutani, Teruo Koike, Takuya Kushimoto, Ryotaro Owada, Masafumi Ohno, Takashi Futami

Patent number: 8070339Abstract: A vehicle lamp including a projector headlight using an LED light source for a low beam can include a shade, an LED light source, an ellipsoidal reflector and a projector lens. Both a focus of the projector lens and a top edge of the shade can be located near a second focus of the reflector. The LED light source can be located near a first focus located below the second focus of the reflector. Therefore, light emitted from the LED light source can be effectively gathered near the focus of the projector lens via the reflector and can be projected via the projector lens with high light use-efficiency. The projector lens can include light dispersing portions or structures on an upside and downside thereof for reducing chromatic aberration. Thus, the lamp can project a favorable light distribution that can conform to light distribution standards for vehicle headlights and the like.Type: GrantFiled: February 23, 2009Date of Patent: December 6, 2011Assignee: Stanley Electric Co., Ltd.Inventor: Teruo Koike
