Abstract:
The invention disclosed herein is a dynamic dummy load to allow a phase control dimmer to be used with LED lighting. The invention includes providing a dynamic dummy load to provide a load to the dimmer when the LED electronics do not provide sufficient load due to start up issues or ringing in the circuit, the dynamic dummy load providing a reduced flow of current when the LED and its converter electronics provide sufficient current draw from the dimmer. The system generally includes a power source electrically connected to a phase control dimmer, the phase control dimmer electrically connected to converter circuitry to convert the AC power output of the dimmer to DC power output for powering the LED lighting, a dynamic dummy load electrically connected in parallel with the converter circuitry, the dummy load varying its current draw in response to operation of the converter circuitry.
