Abstract
An LED light engine includes a housing, one or more LEDs mounted on a printed circuit board and a retention feature engaged with the housing. The retention feature includes one or more of a torsion spring and a friction clip and is configured to engage an inside wall of a recessed lighting can, thereby retaining the LED light engine within the can. The LED light engine may also include a reflector and a lens retained within the housing, with the housing, reflector and lens forming a sealed chamber for protecting the LED components from external environmental conditions. Methods for retrofitting an existing recessed downlight fixture with an LED light engine include removing the existing light engine from the recessed lighting can and inserting an LED light engine into the can.
