Dim to warm lighting module

摘要

The present invention is a lighting module, in particular, a lighting module that emits warmer color light as it dims. The lighting module preferably has a dimmable power source and a printed circuit board having at least two series of LEDs. The first LED series has a resistor and three LEDs that operate at full brightness at a first voltage, e.g. 12v. The second LED series has a voltage regulator, two capacitors and three LEDs that operate at full brightness at a second voltage, e.g. 6v, less than the first voltage. The first series has a different color light output from the second series. The module produces a linear color shift for a range of voltages, e.g. from seven volts to twelve volts.

主权项

1. A lighting module comprising:
a variable voltage power source; a plurality of LED series, where one of the plurality of LED series operates at full brightness when receiving a voltage less than another one of the plurality of LED series; and where one of the plurality of LED series generates a different color light output from another one of the plurality of LED series.
