    摘要: A light gathering module (10) has a body (12) with a first end (14) comprising a single light transmitting surface (16) and a second end (18) having a plurality of arms (20), each arm (20) having an independent light gathering terminus (22) that is rectangular. 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).

    摘要: A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).

    摘要: 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.
