Patent ID: 7784977

Claim:
A method of focusing light emitted by a light emitting diode (LED), the method including reflecting at least a portion of the light emitted by the LED, such that the reflected light radiates away from a focal point, and, after the light has been reflected, focusing at least a portion of the reflected radiated light into a beam by again reflecting the light to direct it into the beam, said reflecting and directing of said portion of the light emitted by the LED away from the focal point and into the beam being effected by means of a pair of reflecting surfaces, CHARACTERIZED in that one reflecting surface is a primary reflecting surface which is concave and in that the other reflecting surface is a secondary reflecting surface, each of the reflecting surfaces being shaped to have a focal point, and in that the reflecting surfaces are relatively aligned and spaced such that their focal points coincide to form said focal point away from which the reflected light radiates.
