A mount for an LED lighting assembly includes a length adjusting shaft having releasable engagement features that allow the length to be adjusted to a desired length, but also the be released and readjusted as needed. The length adjusting shaft can include an external release disposed outside the housing of the LED lighting assembly that is coupled to the releasable engagement and is configured to release the releasable engagement from the adjustment features through a housing of the LED lighting assembly.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.

A friction blade trim retention system is disclosed. The friction blade trim retention system uses friction blades that are biased radially outward to engage the interior wall of a can housing to hold a trim assembly of a recessed light fixture therein. The system includes vertical translating components that include spring biased detents to toggle between an upper position and a lower position. The detent lower position allows the installer to install the friction blade inside the can in a first step. The installer in the second step pushes the trim assembly upward into the can to engage the upper detent, thus completing installation.

Provided is an adaptable fire-resistant housing for a light fixture, comprising: a. a junction box made from steel, the junction box having an opening on a bottom configured to receive the light fixture; and b. an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.

A friction clip includes a coupling portion having a rotating coupling element, a middle portion adjacent the coupling portion, and an end portion adjacent the middle portion and opposite the coupling portion. The middle portion includes a bent out tab having a first interference edge configured to engage an internal wall of a first canister having a first diameter and the end portion includes a second interference edge configured to engage an internal wall of a second canister having a second diameter. Alternatively, a multi-part friction clip includes a first member that is couplable to a light module, and a second member that is removably couplable to the first member. The second member includes a coupling portion configured to removably engage with the first member, a middle portion having a bent out tab that includes a first interference edge, and an end portion that includes a second interference edge.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.

An LED lighting assembly including a sidewall having an outer periphery with a dimension exceeding a maximum opening dimension of a standard-sized light bulb ceiling recess; at least one LED at least partially disposed within the sidewall; a plurality of heat dissipating fins between the sidewall and the LED; and a plurality of air flow channels, each having an air flow intake port defined by a lower portion of the sidewall and at least one of the heat dissipating fins; and an air flow exhaust port defined by an upper portion of the sidewall and at least one of the heat dissipating fins. Heat generated by the LED is transferred to the heat dissipating fins so as to drive a continuous flow of air into the air flow intake port and out of the corresponding air flow exhaust port of each of the air flow channels.

The invention provides a lighting panel, for use for example within a modular surface system, comprising one or more strips of solid state lighting elements associated with a reflector structure. The lighting panel is adapted for improved uniformity of light intensity across the width of its output area. Lighting elements comprise two or more subsets, each subset adapted to collectively generate a different light intensity profile across the width of the panel output window. The subsets are selectively adapted to generate profiles which, when blended, mutually offset one another's deviations from some common mean intensity across the width of the output window, thereby generating a combined intensity profile of improved uniformity. Embodiments include arrangements in which subsets of lighting elements are adapted to have differing actual or virtual optical path lengths to the reflector surface. Also provided are embodiments further comprising an acoustically absorbing back surface, for providing an acoustic dampening function.

Provided is an adaptable fire-resistant housing for a light fixture, comprising a junction box made from steel. the junction box having an opening on a bottom configured to receive the light fixture; and an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.
