Abstract
Power consumed by an LED driver may be reduced by drawing, from an electronic transformer or dimmer, an input current that is constant over a plurality of input voltages. Power derived from the constant input current is provided to the LED driver.
Claims18
A method for reducing power consumed by an LED driver, the method comprising:
- drawing, from an electronic transformer or dimmer, an input current that is substantially constant over a plurality of input voltages;
- and
- providing the input current to power the LED driver.
A system for reducing power consumed by an LED driver, the system comprising:
- a constant-current sink for drawing, from an electronic transformer or dimmer, an input current that is constant over a plurality of input voltages;
- and
- an output driver for receiving the constant input current and powering an LED therewith.
