US Patent 7402961 Circuit for illuminating multiple light emitting devices

A single drive circuit is configured to drive disparate current loads of first and second combinations of compact light emitting devices with respective regulated constant currents. Standard push ON, push OFF latching switches provide independent control of the two lighting loads wherein each switch operates in three states including momentary ON, continuous ON, and OFF. The circuit is readily adapted to providing continuous or pulsed drive to the lighting arrays. Circuits for dimming control, strobe control, and a low battery indicator are also described.
