Abstract: A water sterilizing tube includes a shell, an outer tube, an inner tube and a UV lighting module. The shell has a first end, a second end and an annular wall. The first end is provided with a water inlet and a water outlet. The outer tube is coaxially disposed in the shell. An end of the outer tube communicates with the water outlet. An air gap is formed between the outer tube and the annular wall. The inner tube is coaxially disposed in the outer tube. An end of the inner tube communicates with the water inlet. An extended channel is formed between the outer and inner tubes. The UV lighting module has a UV light corresponding to the outer tube. An axis line of the outer and the inner tube and a direction of light emitting of the UV light are superposed with each other.

Abstract: A fluid cooled lamp includes: a heat conductive pipe has multiple heat conductive surfaces and a hollow channel; multiple illumination modules arranged at each heat conductive surface; a junction assembly for inlet and outlet of fluid including an inlet joint and an outlet joint, the inlet joint and the outlet joint are respectively communicated with both ends of the hollow channel; a flow guiding inner tube communicated with inlet joint and located in the hollow channel, multiple spray holes are disposed in the flow guiding inner tube, the fluid is sprayed from each spray hole and impacts an inner wall of the heat conductive pipe to remove heat.

Abstract: A meshed cooling structure includes a cooling mesh and a thermally conductive component. The cooling mesh includes a plurality of mesh layers. Each mesh layer includes a plurality of cooling wires which are interlaced, and each cooling wire of each mesh layer has a caliber different from one another. The thermally conductive component supports and transfers heat to the cooling mesh. The thermally conductive component includes a base and a plurality of supporting bodies spaced side by side. A supporting height is formed between one side of each supporting body and the other side opposite to the one side. The one side of each supporting body supports and in contact with the cooling mesh. The other side of each supporting body is connected to the base. Each cooling wire and each supporting body are opposite to each other obliquely.
