Abstract

A vehicle reflector lamp includes a curved reflector having a reflective front side and a non-reflective back side opposite the front side. The curved reflector has a light-permeable slot. A light source is positioned behind the non-reflective back side such that light emanates from the light source through the light-permeable slot for reflecting off the reflective front side. An optical sheet is positioned adjacent the front side of the reflector for homogenizing light reflected from the reflector, and a clear outer lens protects the optical sheet, the light source, and the curved reflector from an outdoor environment. The reflector lamp has a lit mode and an unlit mode. When in the unlit mode, ambient light reflects off of the reflective front side. When in the lit mode, light from the light source reflects of at least a portion of the reflective front side.

First claim

The invention claimed is:

1. A vehicle reflector lamp, comprising:
a curved reflector having a reflective front side and a non-reflective back side opposite the front side, the curved reflector having a light-permeable slot;
a light source positioned behind the non-reflective back side such that light emanates from the light source through the light-permeable slot for reflecting off the reflective front side;
an optical sheet positioned adjacent the front side of the reflector for homogenizing light reflected from the reflector; and
a clear outer lens for protecting the optical sheet, the light source, and the curved reflector from an outdoor environment.

2. The vehicle reflector lamp of claim 1 , wherein the curved reflector presents a reflective surface having a chrome appearance.

3. The vehicle reflector lamp of claim 1 , wherein the reflective front side has a concave curvature.

4. The vehicle reflector lamp of claim 1 , wherein the light source comprises a plurality of light-emitting diodes (LEDs).

5. The vehicle reflector lamp of claim 4 , wherein the light source comprises a linear single-string array of LEDs.

6. The vehicle reflector lamp of claim 1 , further comprising an optical cover positioned over the light-permeable slot for smoothing light from the light source.

7. The vehicle reflector lamp of claim 1 , wherein the light-permeable slot is positioned near a first end of the curved reflector having a greater curvature compared to a second end of the curved reflector, opposite the first end.

8. The vehicle reflector lamp of claim 1 , further comprising a homogenous illumination emanating from at least a portion of the vehicle reflector lamp when operated in a lit mode.

9. The vehicle reflector lamp of claim 1 , further comprising a uniform chrome reflective appearance when operated in an unlit mode.

10. The vehicle reflector lamp of claim 1 , wherein the light source is not directly visible through the clear outer lens from outside.

11. A reflector lamp for external use on a vehicle having a lit mode and an unlit mode, comprising:
an array of light-emitting diodes (LEDs) for producing light in the lit mode;
a reflector for reflecting ambient light when in the unlit mode, the reflector having a slot positioned off-center for receiving light from the light source when operated in the lit mode, such that light passes through the slot and illuminates at least a portion of the reflector; and
the reflector having an asymmetrical curvature such that a portion of the reflector opposite the slot is illuminated when operated in the lit mode.

12. The reflector lamp of claim 11 , further comprising an optical sheet adapted to homogenize light reflected from the reflector in both the lit mode and the unlit mode.

13. The reflector lamp of claim 11 , further comprising a clear outer lens for protecting components of the reflector lamp from an outdoor environment.

14. The reflector lamp of claim 11 , further comprising an optical cover adjacent the slot for smoothing light from the array of LEDs.

15. The vehicle reflector lamp of claim 11 , wherein the slot is positioned near a first end of the reflector having a greater curvature compared to a second end of the reflector, opposite the first end.

16. A vehicle reflector lamp, comprising:
a curved asymmetric reflector having a reflective front side and a non-reflective back side opposite the front side, the curved asymmetric reflector having an off-centered slot;
a light source positioned behind the non-reflective back side such that light emanates from the light source through the off-centered slot for reflecting directly off the reflective front side;
an optical cover positioned over the light-permeable slot for smoothing light from the light source;
an optical sheet positioned adjacent the reflective front side for homogenizing light reflected from the curved asymmetric reflector; and
an outer lens disposed adjacent the optical sheet, opposite the curved asymmetric reflector, for protecting the optical sheet, the light source, and the curved asymmetric reflector.
