A reflector and of a holding-plate slidingly attach to each other to form a flangeless trim assembly. The reflector may be removably attached to a spackle-frame. The spackle-frame may be installed within ceiling drywall around a hole for a downlight. The holding-plate may be attached to a lighting module. In a default resting configuration, a top of the reflector butts up against a bottom of the holding-plate because springs push these two parts towards each other. When an opposing force is applied that is greater than the spring's force, then a variable gap is formed between the reflector and the holding-plate, but while the reflector and the holding-plate are still attached to each other. This gap may be used by human finger(s) to both disengage the reflector from the spackle-frame and to pull down the reflector, the holding-plate, and the lighting module from the spackle-frame—all without tools.

A housing for retaining an integrated-lighting-module within the housing may have a main-housing-member that is an elongate hollow member, that is capped at both a top-end and at a bottom-end, by a top-cap and by a bottom-cap, respectively. The integrated-lighting-module may have one or more LEDs (light emitting diodes). The main-housing-member may have internal structural member(s), such as, at least one internal-rib. The main-housing-member may have teeth attachment structures for removable attachment to the bottom-cap. The bottom-cap may have its own teeth attachment structure for removable attachment to a bottom of the integrated-lighting-module. The bottom-cap may have a seat annular shelf structure for supporting and preventing downward movement of the integrated-lighting-module located within the housing. The housing may be implemented as a ceiling-mounted downlight, a track-lighting mounted light, a pendant downlight, or a sconce.

Light systems, systems and apparatus related thereto that aids in the installation and removal of a luminaire as well as eliminates gaps formed in a housing for the light system. The light system includes a spring-loaded attachment system for a light system, a mounting system in which a luminaire can be arranged therein that includes interchangeable plates to accommodate various size and shape luminaires, and a light-blocking rotatable housing assembly for a recessed luminaire.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.

A downlight apparatus includes a light source, a light housing and a stop unit. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The driver box has a wall with an installation escape. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The stop unit is fixed to the installation escape. The stop unit has a switch holder and a wire holder. A manual switch is placed in the switch holder and an enlarged wire head of an power wire is placed in the wire holder. An operation part of the manual switch is exposed outside the driver box. The manual switch is connected to the driver for adjusting a setting of the driver.

The invention relates to a lighting system comprising a light area and a side wall around the light area defining a recess. The light area is located at a base of the recess and a light exit window is located downstream at a top of the recess opposite the light area. The side wall comprises a first wall portion and a second wall portion located upstream of the first wall portion. A clear, transparent pane is provided in between the first and second wall portion, wherein (essentially the whole of) the second wall portion is screened by the first wall portion from a direct line of view through the light exit window.

An adapter assembly for securing a luminaire to a niche formed in a wall of a pool or spa. The assembly comprises a mounting bracket having a rear portion shaped and sized to fit within the niche and a front portion comprising a peripheral flange sized to engage the wall surrounding the niche. The mounting bracket enables the luminaire to be secured thereto and be visible from a front side thereof. The assembly includes at least one clamping device attached to the rear portion of the mounting bracket and configured to secure the mounting bracket to the niche. In a preferred embodiment, the clamping device comprises a clamping arm and drive member. The clamping arm is pivotally connected to the mounting bracket such that the mounting bracket is drawn into the niche and the peripheral flange of the mounting bracket is drawn towards the wall surrounding the niche.
