A solid state lighting device includes a device-scale stamped heatsink with a base portion and multiple segments or sidewalls projecting outward from the base portion, and dissipates all steady state thermal load of a solid state emitter to an ambient air environment. The heatsink is in thermal communication with one or more solid state emitters, and may define a cup-like cavity containing a reflector. At least a portion of each one sidewall portion or segment extends in a direction non-parallel to the base portion. A dielectric layer and at least one electrical trace may be deposited over a metallic sheet to form a composite sheet, and the composite sheet may be processed by stamping and/or progressive die shaping to form a heatsink with integral circuitry. At least some segments of a heatsink may be arranged to structurally support a lens and/or reflector associated with a solid state lighting device.

A lighting device, comprising a housing and at least one mounting clip. The housing comprises an electrical connection region engageable in an electrical receptacle. The mounting clip is pivotable from a first position, where an end region of the mounting clip does not extend beyond a periphery of the housing, to a second position, where the end region extends beyond the housing periphery. Also, a lighting device, comprising a housing, a trim element and at least one mounting clip. The mounting clip is pivotable, such that if the mounting clip is in a second position and then the trim element is rotated, the mounting clip will pivot to a third position, where the mounting clip engages the housing such that the trim element is biased toward a ceiling or other structure in which the lighting device is mounted. Also, methods of installing housings and/or trim elements.

A lighting device, comprising a light engine housing, a light engine comprising one or more solid state light emitters, a diffuser and an energy forwarding element which receives AC voltage and supplies power to the light engine. The light engine housing comprises an electrical connection region which is engageable with an electricity supply device. The light engine housing comprises a first compartment, in which the light engine is positioned and a second compartment. The light engine housing comprises a flange region. The first compartment has an opening which is covered by the diffuser. The lighting device can be mounted such the only elements which are visible from a room are the flange region, a front side of the diffuser and any portion of the first compartment which is between the opening and the open end of the light engine housing. The light engine housing can comprise heat-dissipating fins.

Canopy mounting devices that cover junction boxes of various configurations and provide a pleasing, finished appearance to a resulting installation are disclosed. Certain embodiments of a canopy mounting device include a universal mounting plate integrally formed with a connector of the mounting device such that direct mounting to junction boxes of different configurations is possible. The mounting devices accommodate not only appropriate mountings of junction boxes within ceilings or walls but also inappropriate mountings, such as when junction boxes are recessed too deeply within a ceiling or wall or mounted with junction box edges extending outwardly from the ceiling or wall.
