| Title: |
Multicolored LED Lighting Method and Apparatus |
| Abstract: |
Illumination apparatus and networks of the same including a number of
different embodiments. In one embodiment, the illumination apparatus
comprises a plurality of LEDs including at least two different colors; a
switching device, interposed between the LEDs and a common potential
reference, including at least two switches corresponding to current paths
of the two different color LEDs; a controller that opens and closes the
switches according to a predetermined duty cycle; and a hand-held housing
with a compartment for containing a power source and the common reference
potential, as well as a lens assembly for reflecting light from the LEDs.
Another embodiment is directed to a lighting network including a
controller and a plurality of uniquely-addressable illumination units,
each including two different color LEDs. Each illumination unit includes a
network interface that receives from the controller data comprising LED
intensity values, a memory that stores the intensity values, a controller
that generates pulse width modulated signals having duty cycles
corresponding to the intensity values and a switch that directs current to
the LEDs based on the pulse width modulated signals.
