US 7,605,549 B2 · System and method for current and/or temperature control of light fixture

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.

A method for current and/or temperature control of light fixtures, comprising:

providing a sensor structured to be in communication with a light fixture, to sense a current flow or a temperature of the light fixture, and to communicate an input signal relative to the sensed current flow or temperature;
providing a variable switch structured to be in communication with the light fixture and regulate the current flow of the light fixture in response to a control signal;
providing a controller in communication with the sensor and the variable switch and structured to monitor the input signal communicated by the sensor, to compare the input signal to a condition, and to communicate the control signal to the variable switch to control its operation;
monitoring the current flow or the temperature of the light fixture via communication of the input signal from the sensor to the controller;
regulating the current flow of the light fixture in response to the controller determining that the input signal meets the condition via the controller communicating the control signal to the variable switch, the regulating including a bypass mode should a malfunction occur with the sensor, controller, or monitoring of the current flow, the bypass mode applying a normal current to the light fixtures without regulatory decreasing the current.
