Patent ID: 7522211

Claim:
A photographic studio light module, comprising: a plurality of light emitters having at least two different colors; a driver circuit operably connected to the plurality of light emitters and configured to provide corresponding driving signals to each or groups of the plurality of light emitters; a plurality of light sensors configured to sense a color temperature and an intensity of light emitted by the plurality of light emitters and provide electrical signals representative thereof to the driver circuit, the driver circuit further being configured to receive and process the electrical signals to determine the color temperature and intensity; a flash synchronization circuit configured to receive an external flash input signal; wherein the light module is configured to operate selectively between a first low-level illumination mode providing emitted light of a first color temperature and a first intensity and a second flash mode providing emitted light of a second color temperature, the light module further being configured to operate in the first low-level illumination mode until the external input flash signal is provided thereto whereupon the light module switches to the flash mode and provides a flash output illumination signal, the light module still further being configured to return to the low-level illumination mode after the output flash illumination signal has been provided thereby.
