| Title: |
Apparatus and Method of Using LED Light Sources to Generate a Unitized Beam |
| Abstract: |
An apparatus includes: a plurality of light emitting diodes (LED) of
similar or differing wavelengths; a reflector for collecting energy from
two or more LEDs into an approximately composite beam; and a housing for
distributing this energy into a common aperture. A heat sink and
electronic control for the individual LEDs is included. The LEDs have
different color outputs and are selectively controlled to determine the
color of light from the apparatus. In one embodiment there are at least
two LEDs, at least two reflector cavities, a common combining cavity or
zone, a mounting each of the LEDs within the reflector cavities and a
housing. The LEDs are mounted on the heat sink And selectively driven 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
according to the control of a musical signal.
