Abstract
A recessed lighting unit for supporting an energizing lamp adapted to fit into an electrical socket using a housing. The electrical socket and lamp are mounted in the housing. The housing includes an opening for the passage of light from the lamp to the area to be illuminated. A source of power runs to the socket through a wireway. A heat protection mechanism interrupts the flow of electrical power to the lamp and socket upon the generation of excess heat in the vicinity of the housing. The heat protection mechanism is mounted immediately adjacent the housing in the wireway and forms a structural unit with the housing and a junction box.
