Abstract: A downlight apparatus may include a canister with a canister body and a canister base comprising a female helical thread defined as an engagement host. The downlight apparatus may also include a lamp including a lamp body and a male helical ridge, defined as a lamp ridge. The lamp ridge includes a platform that extends distally from a root of the lamp ridge to a distance ranging from 2 to 20 times greater than the distance between the root and the crest of an Edison screw base thread. The lamp and the canister are structured to secure to one another when the lamp engages with the engagement host.

Abstract: A luminaire comprising a heat sink, a light source to emit a source light, a heat spreader having inner and outer surfaces, and LEDs carried by a circuit board and disposed generally along a periphery of the inner surface and positioned in thermal communication therewith. The luminaire comprises a reflector disposed coextensively with the LEDs and comprising an aperture. An outer edge of the aperture defines an inner rim of the reflector. A light guide positioned between the reflector and the light source exhibits a height defined as the distance between the inner surface of the heat spreader and a plane defined by the inner rim of the reflector. The light guide comprises deformations and/or lens portions configured to change the source light into a shaped light that is directed through the aperture. The deformations are characterized by a common shape positioned about a center of the light guide.
