Abstract
A reflector for focusing light emitted from a light source in a generally planar direction is disclosed. The reflector is matched with the light source that is preferably a light emitting diode (LED) mounted on a substrate. The reflector is mounted over the LED on the substrate. The reflector is made of a clear material. The reflector has a semi-cylindrical front surface and a back surface with an indentation that is compatible with the light source. The reflector has a top reflecting surface divided into two quadrants and a bottom reflecting surface divided into two quadrants. The top quadrants and bottom quadrants are symmetrical in shape and reflect light emitted from the light source in a substantially horizontal plane. The reflecting surfaces may be TIR based or they may be coated with a reflective material in order to focus light from the LED.
