Abstract
Systems and devices for collimating beams of light emitted by a light emitting diode are disclosed. In one embodiment, an optical device comprises a bowl shaped reflector base, a light emitting diode (LED) physically attached to the bowl shaped reflector base, a central reflector in a shape of a hyperbolic cone formed above the LED about a center of the bowl shaped reflector base, and a transparent plate formed around a base of the hyperbolic cone. In the embodiment, the central reflector in the shape of the hyperbolic cone is configured to reflect a portion of light emitted from the LED to an outer edge of the bowl shaped reflector base which in turn substantially reflect the portion of light via the transparent plate almost parallel to an optical axis of the LED.
