Filed:

Feb 26, 1999

Appl. No.:

09/258143

Inventors:

George R. Hulse - Cookeville TN
Joe Parton Young - Sparta TN

Assignee:

Federal-Mogul World Wide, Inc. - Southfield MI

International Classification:

G02B 626

US Classification:

385 50, 385 25, 385 31, 385 39, 385 47, 385 58, 385 66

Abstract:

An optical waveguide connector ( ) includes a first component ( ) defining a first channel portion ( ) formed along a length of an inner surface thereof. The first channel portion ( ) is sized to receive a waveguide ( ). A second component ( ) defines a second channel portion ( ) along a length of an inner surface thereof. The second channel portion ( ) also is sized to receive a waveguide ( ). A fastening mechanism fastens the first component ( ) to the second component ( ) such that the waveguides ( ) are held in position. The first and second channel portions form a channel ( ) having a reflective inner surface ( ) and a central portion ( ). The central portion ( ) surrounds and conforms in shape to the waveguides ( ).

US Classification:

385 31, 385 26, 385 47

Abstract:

A light collector for use with an illumination system, particularly an automotive interior illumination system. The light collector includes several waveguides capable of conducting light through internal reflection with the waveguides being arranged in a stacked configuration. Each waveguide includes an angled input surface at least some of which are oriented at different angles. With this arrangement, light from a single light source can be collected and routed to several locations.

International Classification:

G02B006/10
G02B006/26

US Classification:

385146, 385 31, 385901

Abstract:

An illuminating waveguide having first and second longitudinally-extending unitary portions of differing cross-sectional shape. In use, light is injected into the waveguide at, for example, an end face of the waveguide and the light travels along the length of the waveguide with a portion of the light refracting laterally out of the waveguide along some or all of its length. The second cross-sectional shape can be any of a large number of different conical shapes to help direct the internally reflecting light toward the first portion where it can laterally exit the waveguide. The first cross-sectional shape can take a variety of different forms depending upon the illumination and other aesthetic and functional requirements for a particular application. The surface of the first portion can be treated to control the emission of light from that surface. The surface of the second portion can have a reflective coating to enhance the internal reflection of light within the waveguide so that most of the light exits laterally through the surface of the first portion.

International Classification:

A61M 100

US Classification:

362581

Abstract:

An optical waveguide structure (1000) is configured to receive light from a light source (1020) and distribute the light to output ports. The structure includes a central portion having top and bottom surfaces, peripheral edges and an opening (1070) for receiving the light source (1020). A first waveguide (1010) extends above the top surface of the central portion. The first waveguide (1010) has an input face (1030) at an end nearest the opening (1070). The first waveguide (1010) extends from the opening (1070) toward a peripheral edge of the central portion.
