Spring loaded recessed lighting fixture thermal protection

摘要

An arrangement for mounting a thermal protective device on the outer surface of a housing of a recessed lighting fixture includes a plaster frame having a horizontal portion and a depending portion formed integrally with the horizontal portion. The plaster frame is adapted for mounting in a ceiling opening. A housing has a lamp connected to a source of electrical power and is adapted for mounting within the depending portion of the frame. A thermal protective device is connected in series with the lamp for interrupting the current from the source of electrical power when the temperature on the outer surface of the housing exceeds a predetermined temperature. A retaining device is provided for holding the thermal protective device against the outer surface of the housing to sense the temperature thereon.
