Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stage lights, and more specifically to a waterproof ventilation component for stage lights. Background Art
[0002] The market divides stage lights into indoor lights and outdoor lights according to the usage scenarios. Most outdoor lights on the market have high requirements for the sealing performance inside the lamp cavity, generally need to reach IP65; however, IP54-level waterproof lights, although slightly inferior in dust and water resistance, can basically meet the use requirements of more outdoor scenes such as non-rainstorm weather, and the price is more affordable.
[0003] When outdoor lights are working, the light source will dissipate a lot of heat, quickly heating the gas inside the lamp cavity. Furthermore, the working heat of the many electronic components inside the lamp cavity will continue to dissipate, causing the temperature inside the lamp body to continue to rise. At this time, a pressure difference is generated between the sealed lamp body and the outside air. Designers usually use a breathable valve to balance the air pressure between the lamp body and the outside world. Most of the breathable valves used on the market mainly add a waterproof breathable membrane, which can isolate water vapor from entering as much as possible, but the ventilation efficiency is low, making it difficult to achieve rapid ventilation and rapid balance. When the lamp head focusing assembly is focusing quickly, the pressure difference at this time will cause resistance to the focusing assembly, affecting the accuracy of the operation. Utility Model Content
[0004] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a waterproof ventilation component for stage lamps, which adopts a labyrinth-shaped ventilation channel. On the premise of having good waterproof performance, it can also achieve the effect of rapid ventilation, so that the air pressure in the lamp body can quickly reach equilibrium with the outside world.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a waterproof ventilation component for stage lights, including a ventilation column, a first air hole passing through the center of the ventilation column, at least two groups of grooves extending circumferentially around the ventilation column are arranged along the length direction of the ventilation column, and a plurality of second air holes connected with the first air holes are arranged on the bottom surface of the groove, and also includes a cap covered on the outside of the ventilation column, an annular protrusion is arranged on the inner side surface of the cap corresponding to the groove, a ventilation cavity is formed between the inner side wall of the cap and the outer side wall of the ventilation column, and a ventilating port connecting the ventilation cavity with the outside is formed at the open end of the cap.
[0006] The annular protrusion and the groove form a winding ventilation channel. The gas enters the ventilation column from the first air hole, and then flows to the ventilation cavity through the second air hole. The gas flows along the ventilation channel in the ventilation cavity to the air outlet, and finally enters the outside world. Similarly, the gas entering from the air outlet can also flow in the opposite direction along the ventilation channel, and finally flow out from the first air hole. The staggered arrangement of the annular protrusion and the groove can prevent as many water droplets as possible from passing through, achieving an ideal waterproof effect while also realizing rapid ventilation.
[0007] Furthermore, a gap for gas circulation is provided between the end of the ventilation column and the inner side wall of the closed end surface of the cap. More gas can be accommodated in the ventilation cavity, so that the flow channel of the gas remains unobstructed and the ventilation efficiency is improved.
[0008] Furthermore, a support seat is provided at one end of the vent column close to the open end of the cap, and the first vent hole passes through the support seat. By providing the support seat, the ventilation component can be more conveniently and firmly installed on the outer side wall of other closed cavities.
[0009] Furthermore, a fixing cylinder for fixed connection is arranged at one end of the cap close to the support seat, and a plurality of third air holes are arranged along the circumference of the fixing cylinder to simultaneously connect the ventilation cavity with the outside. The fixing cylinder can be used to firmly sleeve the cap on the ventilation column, and the third air holes are arranged on the fixing cylinder, so that the third air holes are arranged as far away from the second air holes as possible, thereby extending the flow path of the gas and ensuring the waterproof effect.
[0010] Furthermore, a waterproof rubber strip is provided on the end surface of the fixing tube. When the cap is fixedly connected to the outer wall of the sealed cavity, the waterproof rubber strip effectively prevents water vapor from entering the sealed cavity from the connection between the cap and the outer wall.
[0011] Furthermore, the fixing tube has a bent section, and the support seat is provided with a receiving groove for receiving the bent section. With such a configuration, when the support seat is fixedly connected to the outer wall of the sealed cavity, the cap is also fixedly connected together, and the bent section is pressed tightly by the support seat to prevent water vapor from entering from the connection between the ventilation component and the outer wall, further improving the waterproof effect.
[0012] Furthermore, the material of the ventilation column is metal and / or the material of the cap is silicone. The ventilation column made of metal can make the ventilation component more firmly installed on the outer wall of the closed cavity; and dust or lint in the air will adhere to the silicone material to a certain extent. The cap made of the silicone material has a certain dustproof effect, and the silicone has good softness and toughness, which can effectively adjust the ventilation rate.
[0013] Furthermore, a plurality of the second air holes are evenly distributed along the circumferential direction of the ventilation column to ensure a high ventilation efficiency.
[0014] The utility model also provides a stage lamp, including a lamp head, an arm and a chassis, wherein a closed cavity is formed between the lamp head and / or the arm and / or the chassis, and further comprising a ventilation component as described in any of the above items for connecting the outside world with the closed cavity. According to design requirements, the lamp head, the arm or the chassis can be selectively designed as an independent closed cavity, or, in order to facilitate heat dissipation, at least two components are selected from the three to be connected to form the closed cavity, and finally the ventilation component is arranged on the outer wall of the closed cavity to balance the air pressure inside the closed cavity with the outside world, so as to prevent the components inside the lamp head from encountering resistance and affecting the accuracy due to the pressure difference.
[0015] Furthermore, the lamp head and the arm form a closed cavity, and the ventilation component is fixedly connected to the outer wall of the arm. Since most stage lamps have the lamp head pivotally connected to the arm so that the lamp head can rotate relative to the arm, the ventilation component is arranged on the outer wall of the arm to prevent the ventilation component from colliding with the arm during the rotation of the lamp head.

[0026] The annular protrusion 121 and the groove 112 form a winding ventilation channel. The gas enters the ventilation column 110 from the first air hole 111, and then flows to the ventilation cavity 130 through the second air hole 113.

The staggered arrangement of the annular protrusion 121 and the groove 112 can prevent as many water droplets as possible from passing through, achieving an ideal waterproof effect while also realizing rapid ventilation.
[0027] Preferably, the vent may be a ventilation gap between the cover cap 120 and the ventilation column 110 , or may be a vent hole opened in the cover cap 120 .
[0028] Preferably, the vent is arranged away from the second air hole 113 to extend the travel of air in the ventilation cavity 130 and effectively prevent water vapor from entering the closed cavity 600 through the channel.
[0029] Preferably, the number of the grooves 112 is 2, and the number of the annular protrusions 121 is also correspondingly set to 2. Such a setting can ensure the waterproof performance while keeping the volume of the ventilation component 100 as small as possible.
[0030] In a preferred embodiment of the utility model, a gap for gas circulation is provided between the end of the vent column 110 and the inner side wall of the closed end surface of the cap 120.

[0031] In a preferred embodiment of the utility model, a support seat 114 is provided at one end of the vent column 110 close to the open end of the cap 120, and the first vent hole 111 passes through the support seat 114. By providing the support seat 114, the ventilation assembly 100 can be more conveniently and firmly installed on the outer wall of other closed cavities 600.

[0034] In a preferred embodiment of the utility model, the fixing cylinder 123 has a bent section 124, and the support seat 114 is provided with a receiving groove 115 for receiving the bent section 124. With such a configuration, when the support seat 114 is fixedly connected to the outer wall of the sealed cavity 600, the cap 120 is also fixedly connected together, and the bent section 124 is pressed by the support seat 114, preventing water vapor from entering from the connection between the ventilation assembly 100 and the outer wall, further improving the waterproof effect.
[0035] Preferably, the screw 150 is used to simultaneously pass through the support seat 114 and the bent section 124 of the fixing tube 123 , and finally connected to the outer wall of the closed cavity 600 .
[0036] In a preferred embodiment of the utility model, the material of the ventilation column 110 is metal material and / or the material of the cap 120 is silicone material. The ventilation column 110 made of metal material can make the ventilation component 100 more firmly installed on the outer wall of the closed cavity 600; and dust or lint in the air will adhere to the silicone material to a certain extent. The cap 120 made of the silicone material has a certain dustproof effect, and the silicone has good softness and toughness, which effectively adjusts the ventilation rate.
[0037] Preferably, the ventilation column 110 is made of aluminum alloy, which has the advantages of being light and corrosion-resistant.
[0038] In a preferred embodiment of the present invention, a plurality of the second air holes 113 are evenly distributed along the circumferential direction of the ventilation column 110 to ensure a high ventilation efficiency. Preferably, each of the grooves 112 has four evenly distributed second air holes 113 .
[0039] like Figures 5 to 6As shown, the utility model also provides a stage lamp, comprising a lamp head 200, an arm 300 and a chassis 400, wherein a closed cavity 600 is formed between the lamp head 200 and / or the arm 300 and / or the chassis 400, and further comprising the ventilation component 100 described in any of the above items for connecting the outside world with the closed cavity 600. According to design requirements, the lamp head 200, the arm 300 or the chassis 400 can be selectively designed as an independent closed cavity 600, or, in order to facilitate heat dissipation, at least two components are selected from the three to be connected to form the closed cavity 600, and finally the ventilation component 100 is arranged on the outer wall of the closed cavity 600, so that the air pressure inside the closed cavity 600 is balanced with the outside world, so as to prevent the components inside the lamp head 200 from encountering resistance and affecting the accuracy due to the pressure difference. Preferably, the ventilation component 100 can be installed on any side wall of the lamp head 200, the arm 300 or the chassis 400 according to needs.

Since most stage lamps pivotally connect the lamp head 200 to the arm 300 so that the lamp head 200 can rotate relative to the arm 300, the ventilation component 100 is arranged on the outer wall of the arm 300 to prevent the ventilation component 100 from colliding with the arm 300 during the rotation of the lamp head 200.
[0041] Preferably, the arm 300 includes a support frame plate 500 and a shell covering the support frame plate 500, wherein one of the shells is sealedly connected to the support frame plate 500, so that the support frame plate 500, one of the shells and the lamp holder 200 form a closed cavity 600, and the support frame plate 500 is provided with at least one through hole 510, and the ventilation component 100 is connected to the periphery of the through hole 510 so that the first air vent 111 is connected to the closed cavity 600 through the through hole 510.

When the focusing assembly 210 moves rapidly, the gas inside the closed cavity 600 is rapidly compressed or rapidly expanded. At this time, the ventilation assembly 100 can quickly balance the air pressure between the closed cavity 600 and the outside world, thereby ensuring the accuracy of the operation of the focusing lens. At the same time, the maze-shaped ventilation channel effectively prevents water vapor from entering from the ventilation assembly 100.
