ABSTRACT:
A system for current and/or temperature control of light fixtures includes a sensor in communication with a light fixture, sense a current flow or a temperature of the light fixture, and communicate an input signal relative to the current flow or the temperature; a variable switch in communication with the light fixture to regulate the current flow of the light fixture in response to a control signal; and a controller in communication with the sensor and the variable switch to monitor the input signal, compare the input signal to a condition, and communicate the control signal to the variable switch to control its operation. A bypass circuit applies a normal current directly to the light fixture should a failure occur with the sensor, the variable switch or the controller. A method for current and/or temperature control of light fixtures includes providing the system, monitoring the current flow or the temperature of the light fixture; regulating the current flow of the light fixture, and bypassing the monitoring and regulating should a failure occur in the circuitry.
