Patent ID: 11085597

Abstract:
A lighting assembly includes a light source module including at least one LED, an AC to DC converter to receive an AC voltage and supply regulated electrical energy to power the light source module, a lens, and a heat-sinking unified casting. The casting includes a closed rear wall and a sidewall that defines a casting cavity containing the at least one LED. The closed rear wall and the sidewall are formed of a heat conductive material to dissipate heat generated by the light source module, and the sidewall has at least one exterior width dimension of less than 3½ inches. The assembly also includes a front end face coupled to the sidewall, and a twist-and-lock mechanism comprising multiple flanges that extend radially outward from a perimeter of the front end face, and/or at least one groove and/or at least one slot to form a twist-and-lock friction connection with a trim.
