摘要：Methods and apparatus for adjusting the color or color temperature ofcombined light emitted by one or more LEDs () driven by a single switching regulatorcircuit (). Properties of the light output are changed by intentionally varying a sourcevoltage () provided as an input to the regulator circuit (). The connection of differentcolored LEDs in various branches () of the switching regulator circuit () facilitates

adjustment of the respective drive currents provided to the LEDs, and hence the color orcolor temperature of the resulting combined light, merely by adjusting the level of thesource voltage of the regulator circuit.
