Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.

Disclosed is an ultraviolet ray emitting diode lighting device. The disclosed invention comprises: an ultraviolet ray emitting diode for emitting ultraviolet rays; a substrate on which an ultraviolet ray emitting diode is mounted; a base on which a space for accommodating the substrate is formed and an electrode pin electrically connected to the substrate is installed; and a cover, which is provided to surround the ultraviolet ray emitting diode and the substrate and is coupled to the base, wherein the base includes a support guide fitted in the substrate to support the substrate on the base so as to restrict movement of the substrate.

A strip lamp includes a housing, a mask, a light source module and two end covers. The two end covers are arranged at both ends of the housing and form an accommodating chamber with the housing. The accommodating chamber extends along the length direction of the housing, and the light source module is accommodated in the accommodating chamber; the mask includes a light exiting part, a connection part formed by bending towards each other and extending from both sides of the light exiting part, and a pressing part formed at the end of the joint part. The first depression is formed between the joint part and the pressing part, two sides of the housing are extends towards each other to form a buckle part; the light source module includes a circuit board and a light emitting body arranged on the outer surface of the circuit board.

A polymer luminaire including a polymer housing having a longitudinal axis. An electrical board is mounted to an inner surface of the housing. The electrical board has an outer surface defining a plane extending at an angle to horizontal when the longitudinal axis of the housing is oriented parallel to horizontal. A light source is mounted to the electrical board and electrically connected to the electrical board for emitting light from the housing.

The present utility model discloses a lampshade comprising fasteners, a lampshade body and support frames; the lampshade body comprises a light transmitting sheet and a piece of lampshade cloth; the bottom and/or top of the lampshade body are/is designed with soft band-shaped reinforcing ribs which extend in the length direction of the side wall surface and cover the lampshade body and prop up against at least one fastener; in the present utility model, the bottom and/or top of the lampshade body are/is designed with soft band-shaped reinforcing ribs which extend in the length direction of the side wall surface, the integration of the reinforcing ribs and the matching fasteners with the flexibility of the soft material makes the lampshade easy to be packaged and reduce the volume of its package and finally lower the transportation cost.

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 structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.

The present disclosure provides a fixing member for an optical element and an LED lamp with the fixing member thereof. The LED lamp includes a base, an LED plate and the optical element. The LED plate includes a plurality of LED beads, the base including a receiving room that includes a mounting surface formed on the bottom thereof, the LED plate arranged on the mounting surface, and the optical element arranged on a light-emitting side of the LED plate; the LED lamp further includes a pressing member with one end being hinged to the base and the other end being buckled with the base, the pressing member presses against the optical element to keep the optical element on the base, which has advantages that the optical element can be assembled, disassembled and maintained without using tools.

A connection system is provided for modular luminaires, wherein the luminaires are each provided with at least one tapered pillar projecting from a back, the pillar having a top opening. A coupling arrangement is used for coupling the two luminaires together, in the form of a bridge having first and second tapered openings for fitting over the pillars. A sprung retaining clip projects within each opening for passing through the top opening and thereby gripping the pillar.

The present disclosure provides a breathing structure for a lighting fixture, and a lighting fixture comprising the breathing structure. The lighting fixture includes a lamp body which has an inner cavity. The breathing structure includes: a mounting portion, arranged on the lamp body and protruded from the lamp body; a through hole, formed in the mounting portion, the through hole penetrating the mounting portion and being communicated with the inner cavity of the lamp body; a breathable film, arranged on one end of the through hole facing towards an outside of the lamp body; a washer, arranged on the breathable film and provided with a vent slot; and an elastic fastener, fastened on the mounting portion and configured to compress the washer towards a direction of the inner cavity of the lamp body.
