An assembly is provided herein for a lighting fixture and for retrofitting a flush mounted light fixture to be provided with solid state lighting.

A ring-shaped light-distribution component includes a light-distribution component body that has a ring-shaped accommodation space and a light incident surface and a light emergent surface respectively located on two sides of the light-distribution component body. The ring-shaped accommodation space accommodates at least two light-emitting units distributed along its circumference. An inner wall of the ring-shaped accommodation space is the light incident surface, the light incident surface including an inner light incident surface near the center of the ring light-distribution component and an outer light incident surface away from the center. A deflection angle of light projected by the light-emitting unit and deflected by a portion of the light-distribution component body corresponding to the inner light incident surface is a first deflection angle, and a deflection angle of light deflected by a portion of the light-distribution component body corresponding to the outer light incident surface is a second deflection angle.

Methods and apparatus are presented for retaining a dome lens in a lighting element that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting element includes a dome lens that is removably positioned proximal to a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

The present disclosure discloses a mounting assembly for an optical element of a lighting lamp, including a base, a top frame and at least two side frames, one end of each of the at least two side frames is connected to the base and the other end is connected to the top frame; the at least two side frames, the base and the top frame enclose a mounting space for fixing the optical element, and the at least two side frames are configured to be distributed around the optical element and are configured to be connected to a side edge of the optical element. The present disclosure further discloses a light source module and a lighting lamp.

A streetlight device includes a power source portion and a lighting portion. The power source portion includes a driving power source, a power source base provided with a receiving space for receiving the driving power source, and a power source upper cover for closing the power source base. The lighting portion is connected at one end of the power source upper cover. The power source upper cover and the power source base are connected with each other through a hinge assembly. The power source upper cover is provided with a power source mounting assembly, and the driving power source is mounted onto the power source upper cover through the power source mounting assembly.

A housing, which is provided for incorporating a surface lighting element in a wall, includes a base intended to be fixed in the wall and a flap for receiving the surface lighting element. The flap receives the surface lighting element on its face directed toward the outside of the housing and is mounted to pivot on the base by at least one removable link axis making it possible to dismantle and reassemble the flap relative to the base.

A light fixture, and lighting systems and methods, are provided for selectively receiving one of a modulator or a jumper plug at a connector port of the light fixture. The connector port is coupled between and electrically isolates a driver and a light emitting unit of the light fixture. The modulator, when connected to the connector port, is configured to receive unmodulated power from the driver and to provide modulated power to the light emitting unit. The jumper plug, when connected to the connector port, is configured to provide unmodulated power from the driver to the light emitting unit.

A retrofit kit for a light fixture includes a light engine and a mounting bracket. In some aspects, a method of installing the retrofit kit in a light fixture includes installing a mounting bracket in a housing of the light fixture, and placing a light engine in a temporary hanging position. In the temporary hanging position, a hook of a first engine flange of the light engine rests on the mounting bracket and a second engine flange of the light engine opposite from the first engine flange is spaced apart from the mounting bracket.

A courtyard sensor lamp suitable for use in a courtyard is disclosed, including an arm, a cover, and a lampshade (31). The arm includes a fixing end (11) and a hanging end (12) connected to each other. The cover is fixedly suspended from the hanging end (12), and includes an upper cover (21) and a lower cover (23) which can axially rotate relative to each other, and a connection portion (22) connected to the upper cover (21) or the lower cover (23). A switch module (24) is fixed to the upper portion of the lower cover (23) and disposed in the connection portion (22). The connection portion (22) is provided with a through hole (25) corresponding to the switch module (24). The lampshade (31) is fixed below the lower cover (23). A light source (32) is disposed in the lampshade (31). The light source (32) is electrically connected to the switch module (24). The axial rotation between the upper cover (21) and the lower cover (23) rotates the switch module (24) accordingly to a use position or a hidden position. The switch module (24) is hidden, and thus the appearance is good, and the switch module (24) is prevented from being exposed to sunlight or rain.
