Patent ID: 8686643

Claim:
A lighting fixture comprising: a lamp positioned so that at least a portion of an outer jacket of the lamp is within a reflector; the reflector; a thermal sensor inside the reflector for sensing a temperature near the outer jacket of the lamp; a circulating device for circulating air around the outer jacket of the lamp; a control device for sensing an operational state of the lamp and for controlling a circulating device based on the operational state of the lamp, wherein the control device controls the circulating device so that the circulating device is on when the control device determines that the lamp is off and the thermal sensor indicates that the temperature near the outer jacket of the lamp is above a predefined temperature and the control device controls the circulating device so that the circulating device is off when the control device determines that the lamp is on, and wherein the circulating device is off when the thermal sensor indicates that the temperature near the outer jacket of the lamp is below the predefined temperature; and a housing, wherein the lamp, the reflector, the control device, the thermal sensor and the circulating device are positioned inside the housing.
