ABSTRACT:
An arrangement for mounting a thermal protective device including a case in which there is mounted a temperature sensitive element, in a lighting fixture adapted for recessed mounting in a ceiling support surface, includes a receptacle dimensioned for receipt of the thermal protective device. The receptacle is mounted on the interior surface of the side wall of the recess mounted housing of the lighting fixture. The housing side wall defines an aperture predeterminedly located therein with which the temperature sensitive element is aligned for sensing the temperature of the area adjacent the exterior surface of the housing side wall. The receptacle includes fingers for biasing the thermal protective device into engagement with the interior surface of the housing side wall. The receptacle is constructed of reflective material to reflect heat emanating from the lamp of the lighting fixture away from the thermal protective device. In a preferred embodiment, the case of the thermal protective device includes a frame-shaped projection aligned with the temperature sensitive element therein. The projection is receivable in the aperture defined in the housing side wall for securing the thermal protective device in place thereon and for aligning the temperature sensitive element with the aperture.
