A spot lamp holder and spot lamp are provided. The spot lamp holder may include a first housing and a second housing. The second housing may include a mounting cavity. A mounting end of the second housing may be an open end and coupled with the mounting cavity. A first limiting portion and a second limiting portion spaced apart from each other may be disposed on an inner wall of the mounting cavity. A mounting groove may be disposed between the first limiting portion and the second limiting portion. The first housing may include a clamping portion. The clamping portion may be fitted with the mounting groove.

A heat sink for use in a lighting assembly and including a hexagonal body extending a length. The body including an outer surface, an inner surface opposite the outer surface, a lumen defined by the inner surface, at least one hole extending through the hexagonal body from the inner surface to the outer surface, first, second, third, fourth, fifth, and sixth body portions extending the length. The first, second, and third body portions including planar surfaces extending the length. Each of the first, second, and third body portions configured to support an LED strip thereon. The fourth, fifth, and sixth body portions including fins extending outward therefrom. The inner surface including a plurality of fins extending inward and positioned around a perimeter thereof.

A lighting device may include a lens, an emitter configured to emit light through the lens, and a reflector. The reflector may define a cavity that extends from a first end to a second end of the reflector. The emitter may be received in the first end of the reflector, and the lens may be attached to the second end of the reflector. The lens may include teeth that extend from a rear surface of a rim of the lens. The reflector may include a collar at the second end, and the collar may include attachment clips that are configured to lock the teeth in place and retain the lens in attachment to the reflector.

A linear light apparatus includes a light strip, a light passing cover, a main bracket, a bottom holder and a metal clip. The light strip having an elongated substrate mounted with LED modules. The main bracket holds the light strip for the LED modules emitting a light passing through the light passing cover. The metal clip has a first thorn and a second thorn. The metal clip is pressed to one side wall for the first thorn to stab a second insulation layer to electrically connect the bottom holder and the metal clip. The second thorn stabs a first insulation layer for the metal clip to be electrically connect to the first metal part of the main bracket.

A luminaire with a tool-less assembly feature that enhances ease of installation and serviceability in the field. The luminaire's housing defines a compartment accessible via a window adjacent a pair of opposed shoulders. The luminaire further includes a lighting module dimensioned to be received and retained in the window in an interference fit with the shoulders. The lighting module may include an LED module/light guide plate and/or an LED refractor assembly/LED gear tray. A resilient member is supported on the housing in position to abut the lighting module and deflect during insertion of the lighting module through the window, and to at least partially resile to maintain the lighting module against the shoulders in an operative position on the housing. Further, the resilient member is positioned to deflect during removal and to resile to tilt or otherwise assist in ejecting the lighting module from the housing during tool-less disassembly.

A cover for a circuit board including LED illuminants and at least one connection terminals for connection cables on a top side of the circuit board, the cover including a receiving chamber for the circuit board; a light entry side oriented towards the receiving chamber; a light exit side arranged opposite to the light entry side; fasteners configured to arrange the cover at a light influencing component; optical elements arranged above the LED illuminants and configured to emit light emitted by the LED illuminants, wherein the cover forms a cutout for at least the one connection terminal between two of the optical elements that are adjacent to each other, and wherein the cutout is framed by the cover.

A polygonal rotary projection lamp has a base, a polygonal frame, a film set, a polygonal fixing frame, and an illumination set. The base has a disc configured to be driven to spin. The polygonal frame is mounted to the disc and has multiple bottom frame units. The film set is mounted to the polygonal frame and has multiple film units mounted to the polygonal frame and covering the multiple bottom frame units respectively. Each film unit is flat and has a pattern. The polygonal fixing frame is detachably mounted to the polygonal frame and has multiple top frame units respectively connected to the multiple bottom frame units to respectively fix the multiple film units. The illumination set is mounted within the base and emits light toward the polygonal frame. The light passes through each film unit with the pattern to project the pattern.
