LED assembly for rear lamps in an automobile
First Claim
1. A rear lamp assembly for an automobile comprising:
- a first light emitting diode (LED) with a first side-emitting lens;
a second LED with a second side-emitting lens; and
a first reflector at least partially surrounding the first LED and the second LED,wherein the first LED and the second LED are substantially coaxially aligned in the reflector, such that non-reflected direct light emitted by the first LED and the second LED overlap and impinge on a same area of the reflector that surrounds the first LED and the second LED, and wherein the first LED and the second LED are separately controlled for operation in a rear lamp assembly for a motor vehicle.

Abstract
Various techniques are described herein for combining two or more LEDs in a single reflective cavity for a rear lamp in an automobile. The LEDs may be two or more different colors for performing different functions, such as a stop light, a turn signal, and a tail light. In one embodiment, the LEDs have side emitting lenses and are coaxially aligned in a parabolic reflector. The LEDs may be mounted facing each other or mounted in the same direction, or a combination of both. The LEDs may share a common heat sink. A second reflector may be positioned inside a larger reflector, where a first LED is mounted near the focal point of the larger reflector, and a second LED is mounted near the focal point of the inner reflector. Additional LEDs may also be mounted in either reflector and separately controlled.

19. A rear lamp assembly for an automobile comprising:
-
a first light emitting diode (LED) with a first side-emitting lens; a first reflector at least partially surrounding the first LED; a second LED with a second side-emitting lens; and a second reflector at least partially surrounded by the first reflector, the second LED being mounted in the second reflector, the first reflector and the second reflector being arranged such that that light from the first LED and second LED is not mixed within either of the first reflector or second reflector, and such that all light generated by the first LED is blocked from entering an area surrounded by the second reflector, and such that light generated by the first LED and emitted by the first reflector substantially surrounds light emitted by the second reflector, wherein the first LED and the second LED are separately controllable for operation in a rear lamp assembly for a motor vehicle to convey different information. - View Dependent Claims (20, 21, 22, 23, 24, 25)
