Abstract
The inventive dummy load is mounted on the input power cables of a traffic signal while managing the heat load generated by either a resistive and/or capacitive load. Using the inventive dummy load, there is no thermal path back to the light emitting diode (LED) board. The inventive dummy load may be easly installed, removed, or replaced. The dummy load can be retrofit to adapt to a new controller, either by adding to or replacing the dummy load after initial installation or by removing part or all of the dummy load. There is no need to breach the sealed lamp to adjust the dummy load. Thus, field-adjustments can be made. Further, the number of parts required to manufacture lamps for a variety of retrofit applications are reduced, which in turn reduces the cost and complexity of the lamp.
