Multichambered illuminated decorative displays are presented that can be fabricated in various forms, including annular shapes suitable for holiday exhibition as wreaths and trees. The decorative displays, which may be packaged as kits, include an at least one frame (20); a plurality of translucent chambers (44) mounted to the at least one frame (20); a plurality of addressable LEDs (30) positioned so that at least one LED resides within each chamber; and a plurality of translucent to opaque partitions (46) located between adjacent chambers. As the LEDs (30) light up, the chambers (44) appear to emit a diffuse glow. Simultaneously, the partitions (46) at least reduce or completely block the light transmitted between adjacent chambers (44). Due in part to this combination of light transmission, light diffusion, and at least partial light confinement, the decorative displays can present a wide variety of precisely rendered animations in vivid colors.

The present disclosure relates to an LED explosion-proof lamp. The LED explosion-proof lamp includes a lighting portion having a first engagement structure and a first positioning hole, a connecting portion detachably connected to the lighting portion and having a second engagement structure, a second positioning hole, and an opening suitable for accommodating the support rod of the LED explosion-proof lamp, a positioning member detachably inserted into the first positioning hole and the second positioning hole, wherein one of the first engagement structure and the second engagement structure is configured as a sliding groove, and the other of the first engagement structure and the second engagement structure is configured as a protrusion adapted to be inserted into the sliding groove and movable along the sliding groove. The LED explosion-proof lamp has the advantages of simple structure, easy processing and assembly, and high structural strength.

A light-emitting diode (LED) module of an LED luminaire assembly for a harsh and hazardous environment is provided. The LED module includes an LED assembly, a single-piece lens assembly, and an adhesive sealant. The LED assembly includes a plurality of LEDs. The single-piece lens assembly includes a plurality of lenses, wherein the lens assembly includes a groove defining a complete loop and surrounding the plurality of lenses, the lens assembly coupled to the LED assembly, and the plurality of lenses covering at least one of the plurality of LEDs. The adhesive sealant is disposed in the groove and bonded to the lens assembly, the adhesive sealant sealing off the plurality of LEDs from an ambient environment around the LED module.

A glass stem for a highly waterproof LED filament lamp comprises an LED filament without being driven by external power, a glass flare tube, an exhaust tube, a first lead wire having a resistance element, and a second lead wire. The first lead wire is placed in the exhaust tube. The first lead wire, the second lead wire, the top of the exhaust tube, and the top of the glass flare tube are fusion-bonded together. A lower section of the exhaust tube is fused and cut off to an assembly-desired length and then fusion-sealed with the first lead wire to form a glass stem with the resistance element sealed in the middle of the exhaust tube. The first lead wire having the resistance element is disposed inside the exhaust tube, such that isolative insulation is generated between the first lead wire and a second lead wire.

Submersible lights including housings and a multilayer stack for pressure transfer are disclosed. A transparent pressure-bearing window, a window support structure, a circuit element populated with LEDs, and a pressure support structure may be mounted inside the housing. The support structure may be structured to bear at least some of the pressure applied to the transparent window from external pressure sources. The support structures may also be adapted to transfer thermal energy to an exterior environment such as sea water.

The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.
