Abstract: An LED lamp assembly with a substantial heat sink may be inexpensively constructed using sections of extruded metal as the heat sink. The extruded heat sink sections are trapped in latched sandwich structure assuring good thermal contact between the LED light sources and the extruded heat sink and a metal optic. The inexpensive structure may be rapidly assembled.

Abstract: A robust LED lamp may be assembly by forming a heat sinking sandwich with two metal heat sinks positioned around the circuit board and pinned together a heat conductive element. The assembly is positioned by pressing it into a base providing electrical connections. The robust assembly is rapidly assembled, thermally effective in draining or spreading heat from the circuit board and is readily adaptable to a variety of applications lighting. The heat sink may be decorated, colored or otherwise esthetically enhanced for consumer appreciation.

Abstract: A light guide for an automotive tail light may be efficiently made with a plurality of thick planar light guides stacked side by side to have a common input source point at one end, but spread at their respective opposite ends to be arranged to form parallel planes separated sufficiently to project a relatively larger combined image that may suggest in outline a larger object. The relatively thick plates efficiently transmit light. The planar structures direct light efficiently in the horizontal plane. The side by side offset of the output windows creates an image of a larger more readily seen structure.

Abstract: An LED and light guide assembly has an LED with an output surface; a first power input lead electrically coupled to a first pole and having a first surface and a second surface; and a second power input lead electrically coupled to a second pole and having a first surface and a second surface. A unitary, molded light guide has an axially extending, light transmissive body with a light output window. An input window is formed with the unitary, molded light guide being aligned in a zero-gap relationship to capture substantially all the light emitted by the LED. A support is formed integral with the light guide and envelopes a portion of the first surface and the second surface of the first power input lead and the first surface and the second surface of the second power input lead to anchor the guide with respect to the power inputs.

Abstract: A vehicle headlamp includes a first planar array of low and high beam LED light sources; a first primary optical light guide receiving low and high beam light from the LEDs; a first secondary optical light guide receiving and focusing collimated low and high beam light from the first primary light guide as a combination of low and high beam hot spots; a second planar array of LED light sources having a low and high beam LEDs; a second primary optical light guide receiving and collimating low and high beam light from second LED light sources; a second secondary optical light guide receiving said collimated low and high beam light and spreading the light as a combination of low and high beam spread pattern; a housing to mechanically support the LED arrays, the first primary optic, the first secondary optic, the second primary light guide and the second secondary optic.

Abstract: An advanced forward lighting system may be made with a lamp having a first filament and a second filament extending perpendicular to the first filament. The second filament is partially hidden rearward and above the first filament. A reflector forms a main beam from the first filament light and a right or left cast supplemental beam from the second filament light. The second filament's position minimizes glare, and enables a simple advanced forward lighting system from a single standard lamp fitting both right and left side reflectors.

Abstract: An LED lamp (10) has a housing (12) with an interior wall (14) defining a cavity (16). An LED light source (26) is positioned in the cavity (16) and project light in a forward direction. A reflector (28) having a reflective surface (30), a forward opening (32) and a rear opening (34) surrounds the light source (26) and a complex lens (38) closes the forward opening. The lens (38) comprises a first optical refractive element (40) arranged around a peripheral edge (42) and a second optical refractive element (44) centrally located on the lens (38); the first optical refractive element (40) including a plurality of flute lenses (40a) and the second optical refractive element (44) comprising a concavo-convex lens (44a).

Abstract: An automotive headlamp bulb provides the two light or three filament sources in a single bulb. One source may be used to generate a standard headlamp beam, while the second source may be used to generate an augmenting side beam in response to a turning signal. A similar third filament may provide an augmenting beam to the opposite side, or farther to the same side. The single bulb eliminates the need for a second bulb, or a second reflector in an advanced headlamp system with turning light augmentation.

In a preferred embodiment of the invention, the first end (14) of the body also is rectangular. The light gathering module (10) can be fabricated from acrylic, plastic, glass or other suitable material and preferably has no cladding so that light output I maximized. When combined in a housing (32) with a projector lens (34) the light gathering module (10) provides a vehicle headlamp (30).

Abstract: A decorative light tile includes a base, a light source adjacent to the perimeter of the base positioned to illuminate at least a slanted light reflecting area of the base, and a cover mounted on the base adapted to be illuminated by light from the light source reflected off the slanted light reflecting area. Additionally, the light tile includes a bus bar system. The bus bar system includes positioned along a perimeter of the light tile. The bus bar system is electrically connected to the light source and provides a circuit for supplying power to the light source. A light tile system includes a plurality of light tiles, a decorative sheet positioned adjacent to each light tile and illuminated by the light source within the light tile, and a power supply. Each light tile includes a bus bar system connected to a light source within the light tile and the light tiles may be positioned contiguous to each other so that the bus bar systems are in electrical contact with each other.
