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.
Claims20
A lighting system (20) for a vehicle (10), the lighting system (20) comprising:
- a light source (88) comprising one or more LED chips;
- a cover (80) optically coupled with the light source (88);
- and
- a diffuser (96) integrally formed with the cover (80), the diffuser (96) defining a first region (102) and a second region (104), wherein the first region (102) has a first asymmetrical optical element (112) and the second region (104) has a first symmetrical optical element, the first asymmetrical optical element (112) producing an elliptical diffusion pattern.
