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.

Abstract: A headlight is disclosed. The headlight comprises: a light-guiding unit, the inner surface of the front surface of the light-guiding unit being coated with a totally-reflecting material; at least one light-emitting device fixed to the inner surface of the side surface of the light-guiding unit; a power supply unit for supplying power to each light-emitting device; at least one prism arranged on the inner surface of the rear surface of the light-guiding unit so as to reflect light from each light-emitting device; and a control unit for controlling power of the power supply unit, wherein light emitted from the light-emitting device is reflected at the prism and at the inner surface of the front surface and is discharged to the outside of the light-guiding unit. Accordingly, the device usability and efficiency can be improved.
