Abstract
One embodiment of a vehicle lamp assembly may include a housing, which includes a pair of opposing reflective surfaces defining a chamber therebetween. The assembly may further have a single light emitting diode (LED) disposed within the chamber and a lens carried by the housing. At least one of the reflective surfaces may have a grain pattern configured to interact the light emitted from the single LED with the housing in a range between one and five times before the housing directs the light through the lens.
Claims20
A vehicle lamp assembly, comprising:
- a housing having a pair of opposing reflective surfaces defining a chamber therebetween;
- a lens carried by the housing;
- and
- a single light emitting diode disposed within the chamber;
- wherein at least one of the reflective surfaces has a grain pattern such that the housing interacts with light from the diode in a range between one and five times before the housing directs the light through the lens.
A vehicle lamp assembly, comprising:
- a housing having a pair of reflective surfaces defining a chamber therebetween;
- a single light emitting diode disposed within the chamber;
- a lens carried by the housing;
- and
- an opaque member disposed within the chamber and blocking light directed from the single light emitting diode to at least a portion of the lens that is adjacent to the single light emitting diode;
- wherein at least one of the reflective surfaces has a grain pattern such that light interacts with the housing in a range between one and five times before the housing directs the light through the lens.

- wherein at least one of the reflective surfaces has a grain pattern configured to interact the housing with light from the single light emitting diode in a range between one and five times before the housing directs the light through the lens;
- wherein the single light emitting diode has a predetermined angle of throw that directs light toward the reflective surfaces to facilitate the light in interacting with the housing in the range between one and five times before the housing directs the light through the lens.
