Patent number: 7048412Abstract: A lamp has LED sources that are placed about a lamp axis in an axial arrangement. The lamp includes a post with post facets where the LED sources are mounted. The lamp includes a segmented reflector for guiding light from the LED sources. The segmented reflector includes reflective segments each of which is illuminated primarily by light from one of the post facets (e.g., one of the LED sources on the post facet). The LED sources may be made up of one or more LED dies. The LED dies may include optic-on-chip lenses to direct the light from each post facet to a corresponding reflective segment. The LED dies may be of different sizes and colors chosen to generate a particular far-field pattern.Type: GrantFiled: June 10, 2002Date of Patent: May 23, 2006Assignee: Lumileds Lighting U.S., LLCInventors: Paul S. Martin, R. Scott West, Daniel A. Steigerwald

Patent number: 7036968Abstract: A vehicular lamp including a resin-made plain outer cover that covers the lamp body. The plain outer cover has an interior lens step (cylindrical step) formed in a region that faces a gap between an extension element (or a reflector) installed in the lamp body and the inner surface of a leg portion of the outer cover. The lens step optically reduces the gap between the leg portion and the extension element (or a reflector) and thus optically magnifies the leg portion of the outer cover, allowing the lamp to have a sense of stateliness and a sense of luxury seen in the lamp that uses a glass-made outer cover.Type: GrantFiled: September 8, 2003Date of Patent: May 2, 2006Assignee: Koito Manufacturing Co., Ltd.Inventor: Naruhiro Michiba

Patent number: 7033053Abstract: The subject invention relates to automotive head lamp assemblies with a low beam unit and a high beam unit. In an exemplary embodiment, the low beam unit and high beam unit is connected to one another by an adjuster bracket. The adjuster bracket allows for two ball studs to interact with the adjuster bracket. The first ball stud interacts with the adjuster bracket and high beam reflector so that the high beam reflector's vertical axis can be adjusted to make it parallel to the vertical axis of the low beam reflector. The second ball stud interacts with the adjuster bracket and low beam reflector so that both the low beam reflector and high beam reflector are adjusted vertically at the same time and in the same direction.Type: GrantFiled: February 27, 2004Date of Patent: April 25, 2006Assignee: Guide CorporationInventors: Phillip M. Watson, Jo Broshar, Travis S. Floyd

Patent number: 7021803Abstract: A headlight housing (10) is provided. The housing is adapted to be mounted upon a vehicle, the vehicle adapted to ride upon a ground surface (20). The housing includes a front section (12) adapted to emit light from a headlight (24). The housing also includes a top surface (14) of a substantially constant width extending aft of a top edge (11) of the front section, wherein the top surface is oriented substantially parallel with the ground surface when mounted upon the vehicle in an illuminating position. The housing further includes a bottom surface (16) of a substantially constant width extending aft of a bottom edge (34) of the front surface, wherein the bottom surface approaches the top surface as the top and bottom surfaces extend aft to taper a height of the housing. The method of positioning a headlight housing in an aerodynamic position is also disclosed.Type: GrantFiled: December 5, 2003Date of Patent: April 4, 2006Assignee: PACCAR IncInventors: Alec C. Wong, Daniel Farmer

Patent number: 7021804Abstract: A lamp assembly with a multi-stage reflector is described for use with automobile lamps. A singular shield is positioned about a light source inside a housing. A first reflective surface and a second reflective surface are formed on the housing. The singular shield is moveable between a first position and a second position. In the first position, the moveable shield blocks light from striking the second reflective surface, and a main beam is projected from the lamp assembly. In the second position, the moveable shield allows light to strike both the first and second reflective surfaces, and a second beam is projected. Thus, the singular shield may be moved to switch between the main beam and the second beam, creating the ability to alter the functionality of the lamp assembly. More than two reflective surfaces and moveable positions may be used, to create a multitude of possible beam patterns.Type: GrantFiled: August 13, 2003Date of Patent: April 4, 2006Assignee: Guide CorporationInventor: Paul D.

Patent number: 7019334Abstract: Whereas incandescent light bulbs and other similar light sources known in the prior art emit light in all directions, LED lamps emit light in a single direction only, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. The present invention realizes an LED lamp for a light source of a headlamp disposing an LED chip 2 in the vicinity of the focus of a projection means and providing a shielding member 7 covering a portion of the LED chip 2 in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip 2 is magnified and projected in an illumination direction by a projection lens 10 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 10.Type: GrantFiled: September 16, 2003Date of Patent: March 28, 2006Assignee: Stanley Electric Co., Ltd.Inventors: Yasushi Yatsuda, Takashi Ebisutani, Teruo Koike, Takuya Kushimoto, Ryotaro Owada, Masafumi Ohno, Takashi Futami

Patent number: 7019631Abstract: An indicator equipped with a polarized light splitter, which passes and reflects an un-polarized light irradiated from a light source and divides the polarized light into a p-polarized light whose oscillation direction of an electric field is parallel to an incidence plane and an s-polarized light whose oscillation direction of an electric field is perpendicular to the incidence plane. In this indicator, at least one of the p-polarized light and s-polarized light is emitted from the polarized light splitter as a horizontal polarized light whose oscillation direction of an electric field is substantially parallel to a ground.Type: GrantFiled: December 31, 2003Date of Patent: March 28, 2006Assignee: Honda Motor Co., Ltd.Inventor: Toshiya Shikano

Patent number: 7014254Abstract: A fastening device is provided for a component which is installed in a depression in an automotive body part, insertable into the depression from the outside via an inclined assembly position, and lockable in an operating position in the depression by a pivoting movement. In the operating position, a mounting part integrally molded on a first edge area of the component is in operative connection with a first side wall section of the depression, and, on an opposite second edge area of the component, an elastic catch part is provided, cooperating with a second side wall section of the depression. The depression also has two wall sections arranged with distance between them. To create the fastening device, with which the design is simplified and which also ensures rapid and simple installation and removal, a device is inserted between the depression and the adjacent component in the area of the two wall sections.Type: GrantFiled: September 13, 2004Date of Patent: March 21, 2006Assignee: Dr. Ing. h.c.F.
