ABSTRACT:
A self heating thermal protector located in close proximity to a remotely located incandescent light fixture for controlling the flow of current to the lighting fixture by measuring the rate of heat flow from a dedicated heat source. Current is permitted to flow to the lighting fixture when the temperature of the self heating thermal detector is sufficient to avoid deterioration of electrical components such as plastic parts and wire insulation in the associated fixture. The thermal detector interrupts the flow of current to the associated fixture when the temperature of the self heating thermal protector increases to a temperature that is not safe.
