LIGHT EMITTING DIODE REFLECTOR
First Claim
1. A reflector use for with at least one LED, comprising:
- a first reflector surface arranged to reflect a first light ray emitted by the LED through a side wall of the LED into a forward direction, abutting a second reflector surface arranged to reflect a second light ray emitted by the LED, after refraction by total internal reflection within a housing of the LED, into a forward direction, abutting a third reflector surface arranged to reflect a third light ray emitted by the LED through the side wall of the LED into a forward direction.

Abstract
A reflector for use with light emitting devices. Multiple reflective surfaces redirect light emission components of the light emitting device, for example a light emitting diode, into a desired direction. The different light emission components including a total internal reflection light emission component. Paired light emitting devices share common reflector surfaces creating an oval light pattern. Holes in the reflector accommodate electrical components and enhance heat dissipation. A deflector pattern on non-reflector surfaces minimizes sun phantom effect when the reflector is used, for example, in a traffic signal.
