Abstract
An LED light source using back-reflecting collection optics with a supporting structure and heat sink to block only a small amount of light. A reflector has a front and back side with an LED positioned on the front side of the reflector. A heat conducting body is positioned at least partially between the reflector and the LED. The heat conducting body provides a pathway for heat to flow from the LED toward the back side of the reflector.
