Abstract
A lighting system can include a light source comprising one or more LED chips. A cover can be optically coupled with the light source. A diffuser can be integrally formed with the cover. The diffuser can define a first region and a second region. The first region has a first asymmetrical optical element and the second region has a first symmetrical optical element.
Claims18
A lighting system for a vehicle, the lighting system comprising:
- a light source comprising one or more LED chips;
- a cover optically coupled with the light source along a light source central axis;
- and
- a diffuser integrally formed with the cover, the diffuser defining a first region and a second region,
- wherein the first region has a first asymmetrical optical element and the second region has a first symmetrical optical element, the first asymmetrical optical element producing an elliptical diffusion pattern, wherein the first asymmetrical optical element is positioned a first distance from the light source in a z-direction and the first symmetrical optical element is positioned a second distance from the light source in a z-direction, and wherein the second distance is greater than the first distance.

A lighting system comprising:
- a flexible circuit board;
- one or more LED chips on board operably coupled with the flexible circuit board;
- a cover optically coupled with the one or more LED chips on board;
- and
- a diffuser integrally formed with the cover, the diffuser defining a first region, a second region, and a third region positioned between the first region and the second region, wherein the first region defines a first segment having a first optical element and a second segment having a second optical element, the second region has a third optical element, and the third region includes interspersed fourth and fifth optical elements, wherein a first LED chip on board of the one or more LED chips on board defines a center portion, wherein the first optical element is optically coupled with the first LED chip on board, and wherein the center portion of the first LED chip on board is offset from a center portion of the first optical element relative to a light source central axis of the first LED chip on board that is perpendicular to the circuit board.
