ABSTRACT:
A control system is provided for use in conjunction with a lighting fixture which will provide additional safety by avoiding the risk of fire. The safety system provides a number of sensors which are capable of detecting the presence of objects in close proximity to the lighting element and appropriately switching power off when such objects are detected. The actual detection is accomplished by use of a plurality of infrared sensors which create an infrared shield around the bulb of the lighting fixture and insure no objects intrude upon the shielded space while the lighting system is in operation.
