Abstract
A low profile luminaire to be carried by a lighting fixture. The luminaire may include a light source that comprises light-emitting diodes (LEDs), a heat sink thermally coupled to and disposed diametrically outboard of the light source, a reflector in optical communication with and disposed diametrically inboard of the light source, and a light guide in optical communication with at least one of the light source and the reflector and disposed therebetween. Light emitted from the light source may be reflected by the reflector into an edge of the light guide. Light propagating through the light guide may be projected into the environment at a uniform luminance. The luminaire may be dimensioned to cover a nominally sized four-inch can light fixture and/or electrical junction box. A method aspect of the invention details steps for assembling the low profile luminaire with light guide.
