Abstract: A grating structure and a UV light, where the grating structure includes at least two up-down baffles provided at intervals, the upper surface and the lower surface of each baffle is provided with a light absorption layer, two adjacent baffles enclose to form a light outlet; in the light emission direction of the light outlet, each baffle includes the incoming light section, the light filter section and the outgoing light section, and the incoming light section, the light filter section and the outgoing light section are respectively the first plate body, second plate body and third plate body connected in sequence, the upper surface and the lower surface of the light filter section are provided respectively with multiple upper convexes and multiple lower convexes, the height difference of the top of the upper convexes and the bottom of the lower convexes is greater than 1.5 mm.

Abstract: A ventilation-type UV light includes a light body, an air guide structure provided at the bottom of the light body, a UV module, a fan and two air inlets; the air guide structure and the light body enclose to form a mounting space, the UV module is installed inside the mounting space; the fan is provided inside the air guide structure, the bottom of the air guide structure is provided with air outlets, the air inlets are provided on the periphery or bottom of the ventilation-type UV light in an encircling way, and both the air inlets and the air outlets access the mounting space. Air can flow into the mounting space along the air inlets and then can be discharged downward via the air outlets after being sterilized and disinfected by the UV module in the mounting space.

Abstract: A power regulating device and light. The power regulating device includes a mounting base provided on the light; the mounting base provided with a mounting space; variable resistance provided inside the mounting space and electrically connecting to the control power supply of the light; control switch provided inside the mounting space and electrically connecting to the control power supply of the light; regulating part, connecting to the mounting base in a flexible way and provided with the first regulating section and the second regulating section; the first regulating section connecting to the variable resistance, the second regulating section enabling switch of the state of the control switch; compared with existing technology, the light power regulating device provided with the first regulating section and the second regulating section can realize both the continuous power regulating mode and the precise power regulating mode at the same time.

Abstract: A straight-tube UV light includes a light body, end covers and functional subassemblies, where the light body is a hollow, straight tubular structure; the end cover includes the first end cover and the second end cover provided on the left and the right of the light body, the first end cover, the second end cover and the light body enclose to form a mounting cavity; the functional subassemblies include at least the first light source subassembly and the control power supply, provided inside the mounting cavity, the control power supply used for controlling the first light source subassembly to emit UV rays for sterilization and disinfection. This can simplify the protective structure of the light, reduce the volume of the light and improve the sealing property of the light, and derive other types of UV lights to realize standardization and unification of components of different types of UV lights.

Abstract: A straight-tube UV light. The straight-tube UV light includes a light body, end covers, and functional subassemblies. The light body is of a hollow tubular structure provided in a straight line; the end cover includes a first end cover and second end cover provided on a left and right of the light body, the first end cover, the second end cover and the light body enclose to form a mounting cavity. The functional subassemblies include at least the first light source subassembly and the control power supply, provided inside the mounting cavity, the control power supply controls the first light source subassembly to emit UV rays for sterilization and disinfection. This can simplify the protective structure of the light, reduce the volume of the light, and improve a sealing property of the light.
