[0041] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0042] At present, the components with dustproof function are added to the stage lights, but they cannot achieve the purpose of waterproofing when used outdoors. After the stage lights are used for a period of time, the internal components are prone to failure.

[0043] In view of the above problems, an embodiment of the utility model provides a stage light, which can start or close the blinds by adjusting the component 3, so that the stage light has air cooling and dustproof functions, and also realizes structural waterproofing, thereby improving the safety and reliability of the stage light when used outdoors.

[0044] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0045] Figure 1 The present invention is a schematic diagram of the overall structure of a stage light provided by an embodiment of the present invention.

[0046] Figure 2 The present invention is a schematic structural diagram of a stage light provided in an embodiment of the present invention.

[0047] See also Figure 1 and Figure 2 The utility model provides a stage light, comprising:

[0048] The housing 1 has an air inlet and a heat dissipation port which are interconnected;

[0049] The air inlet assembly 2 is arranged on the housing 1, and comprises a dustproof part 21 and a venetian blind 22, wherein the dustproof part 21 is connected to the air inlet, and the venetian blind 22 covers the air guide channel of the dustproof part 21;

[0050] An adjustment component 3, used for starting or closing the venetian blind 22;

[0051] The heat dissipation component 4 is disposed in the housing 1 , and the air outlet end of the heat dissipation component 4 is connected to the heat dissipation port.

[0052] The stage light in this embodiment includes a housing 1, an air inlet assembly 2, an adjustment assembly 3 and a heat dissipation assembly 4, wherein the dustproof part 21 is connected to the air inlet of the housing 1, and the venetian blind 22 can block the passage between the dustproof part 21 and the housing 1, and the venetian blind 22 is opened and closed by the adjustment assembly 3. After the user starts the stage light, the venetian blind 22 opens the air guide passage of the dustproof part 21 under the control of the adjustment assembly 3, so that air enters the housing 1 through the air inlet and the dustproof part 21, and after heat exchange with the heat inside the housing 1, it is discharged from the stage light through the heat dissipation assembly 4 through the heat dissipation port. The dustproof part 21 can be provided to effectively prevent dust, fiber impurities and oil stains in the air from entering the housing 1, and when the stage light is not in use, the venetian blind 22 can block the air guide passage to improve the waterproof effect of the stage light.

[0053] Specifically, the venetian blind 22 can be opened or closed by folding or flipping.

[0054] The connection position of the venetian blind 22 and the housing 1 of the stage lamp provided by the utility model can be freely set according to actual conditions. Several connection setting methods of the venetian blind 22 and the housing 1 are introduced below.

[0055] Figure 1 and Figure 2 A connection relationship between the venetian blind 22 and the shell 1 is shown. In this embodiment, the venetian blind 22 is arranged in the shell 1. At this time, the external air flows through the dustproof part 21 and the venetian blind 22 in sequence, and is discharged from the heat dissipation port under the action of the heat dissipation component 4.

[0056] In another connection relationship between the venetian blind 22 and the shell 1 (not shown in the figure), the venetian blind 22 is arranged on the outer surface of the shell 1. At this time, the outside air flows through the venetian blind 22 and the dustproof part 21 in sequence, and is discharged from the heat dissipation port under the action of the heat dissipation component 4.

[0057] It should be noted that the blinds 22 can be arranged inside or outside the housing 1 to achieve the air-cooled forced heat dissipation and waterproof functions of the stage light. Figures 1 to 3 The venetian blind 22 shown should not be understood as the only implementation form of the embodiment of the present utility model.

[0058] In this embodiment, through the design of the air inlet component 2, the blinds 22 and the adjustment component 3 are used to start or shut down the air-cooled forced heat dissipation. When used outdoors, the waterproof effect of the stage light can be improved and the service life of the stage light can be extended.

[0059] In a preferred embodiment of the utility model, the venetian blind 22 of the stage lamp includes a plurality of louver blades 220 arranged in sequence, and each of the louver blades 220 is movably connected;

[0060] The adjusting component 3 adjusts the shutter blades 220 to be in a closed state where they are sequentially fitted together or in an open state where they are sequentially separated.

[0061] In this embodiment, a plurality of sequentially arranged louvers 220 can be closed and opened by the adjustment of the adjustment component 3 by flipping each louver 22 or overlapping each louver 220 .

[0062] In a preferred embodiment of the utility model, the venetian blind 22 of the stage lamp further comprises a rotating shaft 23 and a frame 24, and each of the louver blades 220 is rotatably connected to the frame 24 via the rotating shaft 23;

[0063] The adjustment assembly 3 includes a motor 31, and the motor 31 is used to drive the louver blades 220 to rotate around the axis of the rotating shaft 23. When the stage light is started, the rotating shaft 23 rotates under the drive of the motor 31, thereby driving each louver blade 220 to flip accordingly, thereby opening the air guide channel of the dustproof part 21.

[0064] In a preferred embodiment of the utility model, the adjustment assembly 3 of the stage light further includes a first cam 32, a transmission shaft 33 and a connecting rod 34;

[0065] The transmission shaft 33 is respectively connected to the motor 31 and the first cam 32, the first cam 32 is hinged to the connecting rod 34, and a plurality of second cams 35 are hinged on the connecting rod 34 along the length direction of the connecting rod 34, and the second cams 35 are connected to the rotating shaft 23. After the motor 31 is started, the transmission shaft 33 drives the first cam 32 to rotate, and the first cam 32 drives the connecting rod 34 to move up and down relatively, thereby driving the second cam 35 to rotate, and finally realizing the rotation of the rotating shaft 23.

[0066] In a preferred embodiment of the utility model, the adjustment assembly 3 of the stage light further includes a spring 36, and the spring 36 is respectively connected to the connecting rod 34 and the frame 24. After the stage light is powered off, the pull rod is reset by the spring 36, which can ensure that the blinds 22 are in a closed state when not in use, thereby ensuring the waterproofness of the stage light.

[0067] In a preferred embodiment of the utility model, the air inlet assembly 2 of the stage lamp further includes a first fan 25, which is arranged in the housing 1, and the air inlet end of the first fan 25 is connected to the air guide channel of the dustproof part 21. However, due to the low air permeability of the dustproof cotton, under the action of the heat dissipation assembly 4, the air exchange between the internal working space of the lamp and the external air is small, and it is difficult to obtain an ideal heat dissipation effect, which seriously affects the heat dissipation performance of the radiator 41. By setting the first fan 25, the flow speed of the air in the air guide channel can be increased, thereby increasing the air exchange volume of the housing 1, improving the heat exchange effect, and ensuring that the heat dissipation assembly 4 has a good heat dissipation effect.

[0068] In a preferred embodiment of the utility model, the dustproof part 21 of the stage light comprises a hollow shell 211 and a dustproof filter 212, wherein a chamber for receiving the dustproof filter 212 is provided in the hollow shell 211, and the hollow shell 211 is arranged on the air inlet;

[0069] The venetian blind 22 covers the air guide channel of the hollow shell 211. When the dustproof part 21 needs to be disassembled for maintenance, the hollow shell 211 can be disassembled and the dustproof filter assembly can be taken out from the hollow shell 211 for replacement.

[0070] In a preferred embodiment of the utility model, the hollow shell 211 of the stage lamp comprises a first hollow buckle plate 2111 and a second hollow buckle plate 2112 which are snap-connected to each other, the second hollow buckle plate 2112 is provided with a receiving groove 2113 for receiving the dust filter 212, the second hollow buckle plate 2112 is embedded in the air inlet, and the receiving groove 2113 is located inside the shell 1, the first hollow buckle plate 2111 is snap-fitted with the second hollow buckle plate 2112, and the first hollow buckle plate 2111 is fixed to the shell 1 by bolts; the size of the venetian blind 22 matches the size of the second hollow buckle plate 2112. Please refer to Figure 4 , and combined with Figure 2 In this embodiment, the buckle between the first hollow buckle plate 2111 and the second hollow buckle plate 2112 can be quickly fixed or disassembled, which is convenient for quick assembly or disassembly of the hollow shell 211.

[0071] In a preferred embodiment of the present invention, the dustproof filter 212 of the stage light is a dustproof sponge. Of course, other filters known in the art, such as activated carbon, may also be used.

[0072] In a preferred embodiment of the utility model, the heat dissipation assembly 4 of the stage light comprises a radiator 41, a first annular copper tube group 42, a second annular copper tube group 43 and a plurality of second fans 44;

[0073] One end surface of the heat sink 41 is used as a heat source action surface in contact with the light source 11;

[0074] The evaporation end and the condensation end of the first annular copper tube group 42 are passed through the radiator 41, the evaporation end of the first annular copper tube group 42 is close to the heat source action surface, and the condensation end of the first annular copper tube group 42 is far away from the heat source action surface;

[0075] The second annular copper tube group 43 is located inside the first annular copper tube group 42, and the evaporation end and the condensation end of the second annular copper tube group 43 are both penetrated by the radiator 41;

[0076] A plurality of the second fans 44 are disposed on the outer periphery of the radiator 41, and the air outlet ends of the second fans 44 correspond to the heat dissipation ports;

[0077] The first annular copper tube group 42 and the second annular copper tube group 43 are filled with liquid working medium for heat exchange.

[0078] Specifically, see Figure 5 In this embodiment, the heat generated by the stage light heat source is transferred through three paths: the first annular copper tube group 42, the second annular copper tube group 43, and the radiator 41 itself. After the heat is transferred to the radiator 41 through the heat source action surface, the heat is first absorbed by the evaporation end of the first annular copper tube group 42. The liquid working fluid at the evaporation end is heated and vaporized and then flows to the condensation end located in the radiator 41. Condensation occurs under the coordinated action of the radiator 41 and flows back to the evaporation end. After the heat source passes through the first annular copper tube group 42 for heat exchange, part of the heat is lost, and the remaining heat is exchanged through the evaporation end and the condensation end of the second annular copper tube group 43. Finally, the remaining heat is diffused through the radiator 41 itself, thereby realizing the gradient heat exchange of the heat source, improving the overall heat conduction and heat dissipation effect of the radiator 41, prolonging the thermal equilibrium time inside the stage lamp, reducing the maximum temperature of thermal equilibrium, and realizing forced air cooling of the radiator 41 through the second fan 44, quickly reducing the core temperature of the light source 11, and avoiding the defect of light decay of the light source 11 due to overheating. The liquid working fluid can be water, ethanol, cooling oil or coolant, etc.
