| Title: |
Methods and Apparatus For Providing Power To Lighting Devices |
| Abstract: |
Methods and apparatus for providing power to devices via an A.C. power
source, and for facilitating the use of LED-based light sources on A.C.
power circuits that provide signals other than standard line voltages. In
one example, LED-based light sources may be coupled to A.C. power
circuits that are controlled by conventional dimmers (i.e, "A.C. dimmer
circuits"). Hence, LED-based light sources may be conveniently
substituted for other light sources (e.g., incandescent lights) in
lighting environments employing conventional A.C. dimming devices and/or
other control signals present on the A.C. power circuit. In yet other
aspects, one or more parameters relating to the light generated by
LED-based light sources (e.g., intensity, color, color temperature,
temporal characteristics, etc.) may be conveniently controlled via
operation of a conventional A.C. dimmer and/or other signals present on
the A.C. power circuit.
