Abstract

A lighting device for reducing glare from light emitting diodes (LED) includes at least one LED light source including an optical axis, a housing encompassing the LED light source for capturing light emitted from the LED light source during operation of the lighting device, a first surface positioned within said housing in front of the LED light source for receiving light from the LED based lighting device, and a second surface positioned within the housing lateral to the first surface for receiving light from the first surface, and an output surface for receiving light from said second surface. Particularly, the LED light source operates without any reflective coating.
