A luminaire comprises a first housing element which includes at least one groove, a second housing element, and a clamping member. The clamping member of a generic luminaire further comprises a first connection area and a second connection area, the first connection area interacting with the groove and the second connection area being connected, in the assembled state, to the second housing element so that the second housing element is clamped by the clamping member relative to the first housing element. The clamping member is pivotably mounted in the groove, in a plane perpendicular to the longitudinal extension of the groove.

The present invention discloses a displayer screen hanging lamp, comprising a lamp body and a fixed bracket, wherein the lamp body comprises a lamp housing, a lens and a light source; the fixed bracket comprises an regulating frame, a support clamping mechanism and two clamping legs; the lamp body is connected and fixed with the regulating frame which is installed onto the support clamping mechanism, the forepart of the bottom of the support clamping mechanism is equipped with two clamping feet extending downward; the whole fixed bracket is clamped onto the displayer via the clamping feet and the clamping legs; the clamping feet clamp the front surface of the top of displayer and the clamping legs are rotated to change the clamping angle to clamp the back of displayer. The present invention can stably and conveniently install the whole lamping lamp onto any displayer of any specification and thickness through two clamping legs, two clamping pieces, two supporting arms and a regulating frame designed for interaction and it does not cover over the displayed content; the regulating frame is set with a clamping leg on its left and right sides respectively, not only solving the problem that the clamping legs interfere with the displayer bracket but also making the lamplight irradiate in front of the displayer. The lamp body is designed with a light-polarizing lens so that the lamplight does not irradiate towards the displayer to prevent the displayer from being not seen clearly due to lamplight reflection.

A sconce box assembly for mounting sconces on walls of various wallboard thicknesses and shallow wall cavities with no disruption to the surrounding wall. The sconce box assembly includes an electrical box having a sidewall, a back wall, an electrical cavity, and wing bosses extending from the sidewall. First rotatable wings secured to the wing bosses are adapted for rotation between a retracted position, in which the rotatable wings are positioned inside the sidewall perimeter, and an extended position in which the rotatable wings are positioned outside the sidewall perimeter. Retracting the wings facilitates insertion of the electrical box through a hole in a wall. Extending the wings facilitates tightening the wings and clamping the electrical box to the wallboard. The invention contemplates at least one second rotatable wing that may be used optionally in place of the first rotatable wing in order to accommodate attachment to various thicknesses of wallboards.

The invention provides an elongated lighting element (200) for attachment to a building part (10) selected from the group consisting of a wall (11), a ceiling (12) and a floor (13), wherein the building part (10) comprises a first attachment unit (131) and a first electrical power connector (141), wherein the elongated lighting element has a front side (210) and at the other side of the front side (210) (i) a second attachment unit (231) for forming with the first attachment unit (131) said attachment to said building part (10), (ii) a second electrical power connector (241) for forming an electrical connection with the first electrical power connector (141), and (iii) a plurality of solid state based light sources (250) configured to provide light source light (251) and functionally connected with the second electrical power connector (241).

There is provided a white light source approximating sunlight and being capable of reproducing a subtle difference in sunlight which changes depending on times and locations, and provided a white light source system of a lighting system or the like. The white light source includes a light source unit. Light which is emitted from the light source unit is a chromaticity point on a CIE chromaticity diagram and has a correlated color temperature corresponding to a chromaticity point including a deviation of −0.005 or more to +0.005 or less with respect to a black body radiation locus, and satisfies a formula: −0.2≦[(P (λ)×V (λ))/(P (λmax1)×V (λmax1))−(B (λ)×V (λ))/(B (λmax2)×V (λmax2))]≦+0.2.

A wall pack light fixture including a front cover having a front surface, a top wall, and two side walls, the top and side walls extending rearward from the front surface and defining a recess with an inner contact surface, a light element in the front cover, a rear enclosure having a forward-facing front edge, and a hinge having a first portion connected to the front cover and a second portion pivotably coupled to the first portion, the second portion connected to the rear enclosure, wherein the front cover is rotatable about the hinge between a closed configuration, in which the forward-facing front edge is within the recess and against the inner contact surface, and an open configuration, wherein the top wall of the front cover is a continuous surface which, in the closed configuration, extends over a top portion of the forward-facing front edge of the rear enclosure.

A lamp includes a first body and a second body. The first body has a protrusion, a first engaging portion and two ribs. The second body has a second engaging portion which is engaged with the first engaging portion. The second engaging portion has two L-shaped connection slots with which the ribs are engaged.

The second body has a first guide path and three second guide path. Two inclined ramps are located in the first guide path so that the protrusion of the first body slides along the inclined ramps to guide the first engaging portion to be engaged with the second engaging portion. The protrusion is restricted by the contact faces of the blocks to restrict that the second body can only be rotated in one direction to engage the ribs with the connection slots.

The present invention comprising a base having a base element comprising a mounting surface and at least two edged sides protruding outwards in relation to the mounting surface and where a number of electronic components are mounted at the mounting surface and between the edged sides; a yoke is connected to and rotatable relative to the base and a head is connected to and rotatable relative to the yoke. The head comprises at least one light source generating a light and the base element is formed as one piece molded body.

A mounting apparatus for profiles with a cover that allows simple and quick assembly without using any additional hinge or locking element in products with a lidded structure that can be produced with aluminum profiles.

The multiple functions wall cover plate has built-in USB and light means connect by prong means to existing wall inner-kit's receptacle to get AC power source to multiple function wall cover's circuit(s) to drive each circuit for predetermined functions. The said cover plate fasten by screw, prong or false prong to hold on inner-kit's holder and overlay at least one of the inner receptacle to offer people safety and quickly USB charger with desire light illumination and add extra functions.
