A light string structure includes a clip and a light source assembly. The clip is connected to the light source assembly, and a plurality of the light source assemblies are provided. Each light source assembly includes a light cover. The clip is arranged on a bottom portion or a side surface of the light cover. The clip and the light cover are integrally connected. The clip is elastic. The clip includes a clipping portion and inclined portions. An end of the clipping portion and the light cover are integrally connected. The clipping portion protrudes outwards and bends to form an arch-shaped concave portion. The inclined portions are respectively disposed at the end portions of the clipping portion and are integrally connected to the clipping portion. The inclined portions are respectively arranged inclined in directions opposite to bending directions of the clipping portion.

A holiday tree light source assembly for inserting a plurality of universal serial bus inputs includes a tree being displayed as a holiday decoration. The tree has a trunk with a plurality of branches protruding off from the trunk. Each of the branches is an electric wire having a plurality of plastic pine leaves. The tree has a bottom base where a power source is positioned proximate to. Furthermore, a plurality of universal serial buses is coupled to the electric wire of each of the branches of the tree. Each of the universal serial buses has a port being a female insert to a universal serial bus input. Each ornament of a plurality of ornaments has a universal serial bus input. The universal serial bus input of each of the ornaments is a male insert to the port of the universal serial bus of the tree.

A lighting system includes two or more three-dimensional structural frames that are joined to one another by at least one shared frame component and at least one shared connector to form a modular structural frame. The frames can be fitted with a light emitting panel for emitting light downwardly. The frames can be suspended from a ceiling via suspension cables or can be fixedly mounted to a ceiling.

A light puck that attaches to a wire rope tension grid has a top cover with a plurality of slots to receive wire ropes therein and a corresponding bottom cover. There is also a light fixture having a plurality of LEDs disposed between the top cover and the bottom cover, the light fixture aligned with an opening in the bottom cover. A biasing plate is positioned between the light fixture and the top cover and has adjustment screw associated therewith to bias the biasing plate relative to the top cover.

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.
