AN APPARATUS AND METHOD OF USING MULTIPLE LED LIGHT SOURCES TO GENERATE A UNITIZED BEAM

摘要

An LED package is comprised of a plurality of light emitting diodes (LED) of similar or differing wavelengths; means for efficiently collecting energy radiating from two or more LEDs into an approximate unitized beam; and means for distributing this energy into a common aperture. A means provides thermal management of the LED package and electronically controls the individual LEDs. The LEDs can have different color outputs and means for selectively controlling the color of light from the LED package. In one embodiment there are at least two LEDs1 at least two reflector cavities, a common combining zone or zone, a means for mounting each of the LEDs within the reflector cavities and a housing, and the LEDs are mounted on a heat conductive material that provides the thermal management for the LEDs. The LEDs are further selectively driven by an input signal to modulate the intensity of selected ones of the LEDs according the nature of the frequency bands in the driving signal, e.g. mixed color outputs are obtained from the LED package according to the control of a musical signal.
