Estimating the term…
The present disclosure provides a supplemental load circuit configured to provide a supplemental power consumption to enable a lamp unit operating at a low power consumption to operate with a traffic controller configured to test for a higher power consumption. The supplemental load circuit includes a load, power input circuitry configured to receive a DC power signal from the lamp unit, and a control switch configured to receive a control signal having a duty cycle from the lamp unit. The control switch is configured to control application of the DC power signal to the load by the power input circuitry based on the duty cycle of the control signal. The present disclosure also provides a method for enabling a lamp unit to operate with a traffic controller designed for higher power lamp units.
