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.

Lighting fixtures that include fixture housings and light-emitting diode (LED) modules configured for tool-less attachment and detachment to the fixture housings are disclosed. Certain LED modules include LED emitters, corresponding electronics for operating the LED emitters, and at least one shaped protrusion. Certain LED modules include safety tethers that are configured to provide mechanical support during the tool-less attachment and detachment. Lighting fixtures include a lens and removable endcaps that secure the lens to the fixture housing. Certain lighting fixtures include a backup battery and a button provided in one of the endcaps for testing the backup battery. Certain lighting fixtures include a cut-out portion in the fixture housing corresponding to the shaped protrusion of the LED module for providing identification of replacement LED modules that may be attached to fixture housings.

The present utility model provides a flexibly deformable hard linear lamp, which comprises a plurality of light source assemblies and connection assemblies connecting the light source assemblies. The connection assemblies are flexibly snap-fitted into the through holes at adjacent ends of adjacent light source assemblies, so that both the spacing and included angle of two adjacent light source assemblies can be adjusted within a certain range. Therefore, the deformation angle is flexible and the length varies flexibly; and a single lamp can meet the deformation requirements, so that the cost is reduced, and at the same time the wiring is simple and aesthetic; the spacing of adjacent light sources may be consistent, so that the light spots are evenly distributed, and there is favorable light effect. It is suitable for both specially shaped projects and large-scale commercial lighting projects.

An airfield light, components thereof, and associated methods. The airfield light can include a baffle including a baffle body and one or more baffle members secured to the baffle body. The baffle members are configured to cover portions of a baffle window. At least one light source is mounted in association with the baffle and emits light out of the baffle window. The baffle members cover portions of the baffle window for blocking light transmission therethrough. A method of assembling an airfield light includes arranging a baffle to shroud a light assembly and removing a baffle member to permit light from the light assembly to emit through a portion of a baffle window opened by removing the baffle member. A baffle for an airfield light is also disclosed.

A spot lamp, including a lamp body, a light source, a surface ring and a rotation connector, which is characterized in that the spot lamp includes a main body portion and an adjusting installation portion, which are separable from each other, the main body portion includes the lamp body, the light source and a first magnetic connection portion, and the adjusting installation portion includes the surface ring, the rotation connector and a second magnetic connection portion, the main body portion and the adjusting installation portion are connected by mutual attraction of the first magnetic connection portion and the second magnetic connection portion.

Examples of the present disclosure disclose a cylindrical lighting fixture, which includes a body, a plurality of light source modules and a plurality of diverging lenses. The body has an axis, the body has two ends, the two ends are penetrated by the axis, the plurality of light source modules are arranged on the body around the axis, the light source module includes a light source plate and a light-emitting unit, the light-emitting unit is arranged at a side of the light source plate away from the body, and each diverging lens covers one of the light source modules; and the diverging lens includes an inner surface facing the axis and an outer surface away from the axis, the inner surface is recessed to form a cavity, the cavity extends in the same direction as the axis, and the light-emitting unit is arranged in the cavity.

The present disclosure relates to an assembly component, a lamp and a method of manufacturing an assembly component. The assembly component includes a first element and a second element, the first element includes a first main body and a first elastic engaging portion which are connected to each other; the second element includes a second main body and a second engaging portion; the second main body has a moving space; a bottom wall of the moving space forms a clamping surface, the second engaging portion is connected to a side wall of the moving space, the first elastic engaging portion is clamped between the second engaging portion and the clamping surface, and the clamping surface limits the first elastic engaging portion in an outward direction.

A lighting module includes a heat sink having a sidewall and a partition that define a first cavity and a second cavity; a driver enclosure disposed in the first cavity and electrically insulated from the heat sink; a light source disposed in the second cavity; an optical element positioned over the light source; a retaining ring/optic cover closing the second cavity; and a trim mechanically and electrically coupled to the heat sink. The lighting module is shaped and dimensioned to fit into a space having a width less than 2.4 inches, a height less than 2.25 inches, and a volume as small as 18 cubic inches. The heat sink includes at least one curved keyed feature reducing the volume of the heat sink and providing sufficient clearance for the heat sink to fit within an enclosed space.

The present disclosure provides a lamp holder assembly and lamp device thereof, including a lamp body, which includes a housing, a heat radiator, a plurality of light-emitting devices, and a lens. The heat radiator is placed in a receiving cavity of the housing. The heat radiator includes a platform for attaching each of the light-emitting devices. The lens covers an opening at one end of the housing to fix the heat radiator. At least one top surface of a platform facing the light exiting direction has a certain slope relative to the horizontal direction perpendicular to the light exiting direction.
