Description

TECHNICAL FIELD

[0001] The utility model relates to stage lamp technical field especially, it relates to a stage lamp convenient to dismouting heat abstract system. BACKGROUND

[0002] In the field of stage lamp, heat dissipation is one of the key factors to guarantee the performance and service life of the lamp, and the liquid cooling heat dissipation system has been applied due to its high heat dissipation capacity. The liquid cooling heat dissipation system of stage lamp is mainly composed of cold plate, pump body, cold row, connecting pipe and heat transfer medium. Its heat dissipation principle is as follows: a large amount of heat is generated at the lamp head light source of stage lamp, the cold plate is installed at the lamp head light source position, the heat is first transferred from the light source to the outer wall of the cold plate through heat conduction, and then to the heat transfer medium in the inner cavity of the cold plate. After the heat transfer medium evenly disperses the heat in the inner cavity of the cold plate, the heat is transferred to the inner surface of the heat dissipation cold row through convective heat exchange, and then to the outer surface of the cold row through heat conduction, and finally the heat is dissipated by the external air flow and fan assistance. However, the connecting pipe and each component of the existing stage lamp liquid cooling heat dissipation system adopt fastening connection mode to ensure the sealing, and this connection mode has serious problems:

[0003] I. Maintenance

[0004] When the connecting pipe and the heat dissipation cold row of the stage lamp need to be disassembled and operated, such as repairing or replacing the cold row, the space between the cold plate inner cavity and the connecting pipe must be vacuumized and a series of air tightness detection. This process is very complex and time-consuming, which requires professional equipment and technical personnel. From the manpower point of view, the technical personnel need to spend a lot of time for operation; from the time cost, the whole process will make the stage lamp unable to be used normally for a long time, which seriously affects the maintenance efficiency and convenience of the stage lamp.

[0005] II. Structural flexibility

[0006] In the structural design of stage lamp, the cold plate is located at the lamp head light source, and the heat dissipation cold row is installed on the support frame, and the two are often far apart. Because the connecting pipe adopts rigid fastening connection, when the angle of the lamp head needs to be adjusted during the stage performance, the connecting pipe greatly limits the relative rotation movement between the lamp head and the support frame. Stage performance often requires the lamp to be adjusted in multiple angles and all directions, but this fastening connection mode makes the stage lamp unable to be operated flexibly in actual use, which cannot meet the demand of stage performance for light adjustment.

[0007] The root cause of these problems lies in that the existing connection mode excessively depends on fastening connection, and lacks a mechanism that can ensure the sealing and facilitate the quick connection and disassembly in the structure of stage lamp, thereby limiting the application and performance improvement of liquid cooling heat dissipation system in stage lamp which has high requirement for flexibility.

[0026] The circulation pipe is connected in series with the heat dissipation fin assembly, and the fan vent corresponds to the heat dissipation gap of the heat dissipation fin assembly.

[0027] This utility model discloses a stage light with an easy-to-assemble and disassemble heat dissipation system. The heat dissipation system structure adopts a traditional liquid cooling system, comprising a heat-absorbing plate in close contact with the light source to absorb heat generated by the light; a pump body as the power source for circulating the heat transfer medium; a radiator to dissipate the absorbed heat to the outside; and a circulation pipe connecting the pump body, heat-absorbing plate, and radiator to form a closed circulation loop. The pump body drives the heat transfer medium in the circulation pipe to circulate between the heat-absorbing plate and the radiator, thereby transferring the heat generated by the light source from the heat-absorbing plate to the radiator for dissipation. In addition, at least one quick-release connector is added to the heat dissipation system. This quick-release connector is located at the connection point between the heat-absorbing plate, pump body, radiator, and circulation pipe. When connection is needed, the quick-release connector can connect the various components of the heat dissipation system to the circulation pipe, allowing the heat transfer medium to flow within it. When disassembly is needed, the quick-release connector can be used to separate the various components of the heat dissipation system from the circulation pipe, while simultaneously restricting the outflow of the heat transfer medium and preventing outside air from entering the medium pipe. When the stage lights are working, the light source generates heat. The heat absorber plate is in close contact with the light source, efficiently absorbing the heat. The pump starts, driving the heat transfer medium in the circulation pipe to flow. The heated heat transfer medium flows out of the heat absorber plate, through the circulation pipe to the radiator. In the radiator, the heat transfer medium releases the absorbed heat into the surrounding environment. The cooled heat transfer medium continues to flow in the circulation pipe, returning to the pump body, and then flowing back to the heat absorber plate, forming a closed loop. When maintenance or replacement of parts of the heat dissipation system is required, the quick-release connector can be used to quickly separate the heat absorber plate, pump body, or radiator from the circulation pipe. During separation, the quick-release connector restricts the outflow of heat transfer medium through an internal sealing mechanism, preventing media leakage and air from entering the piping system. After maintenance or replacement, the quick-release connector can be used again to quickly reconnect the separated parts to the circulation pipe. After connection, the quick-release connector opens the fluid passage, allowing the heat transfer medium to continue circulating. By introducing quick-release connectors, the disassembly and installation of each component of the heat dissipation system can be carried out without complicated tools and operations, greatly shortening maintenance time, reducing maintenance difficulty, and improving the convenience and efficiency of stage lighting heat dissipation system maintenance. When separated, the quick-release connectors can restrict the outflow of heat transfer medium and prevent air from entering. Therefore, after reconnection, there is no need to perform tedious vacuuming and airtightness testing, simplifying the maintenance process and avoiding the tedious vacuuming and airtightness testing required after disassembly and assembly of traditional liquid cooling systems. Therefore, this utility model enables the disassembly and assembly of each component of the stage lighting heat dissipation system to be carried out without complicated operations, shortening maintenance time and reducing maintenance difficulty, which helps to improve the convenience and efficiency of stage lighting heat dissipation system maintenance. At the same time, after the heat dissipation system is disassembled, it can restrict the outflow of heat transfer medium and prevent the entry of outside air, thus avoiding the tedious steps of vacuuming and airtightness testing required after the heat dissipation system is disassembled, simplifying the maintenance process.

[0038] like Figures 1 to 5 As shown, this embodiment of a stage light with an easy-to-assemble and disassemble heat dissipation system includes a base housing 100, a support arm 101, a lamp head 102, and a heat dissipation system. The lamp head 102 is pivotally connected to the support arm 101 on opposite sides, and the support arm 101 is pivotally connected to the base housing 100. A light source 103 is installed inside the lamp head 102. The heat dissipation system is a liquid cooling system, which includes a heat-absorbing plate 1, a pump body 2, a radiator 3, and a circulation pipe 4. The heat-absorbing plate 1 contacts the bottom of the light source 103 inside the lamp head 102. The circulation pipe 4 connects the pump body 2 and the heat-absorbing plate 1 and passes through the radiator 3. The heat transfer medium in the driving circulation pipe 4 circulates within the circulation pipe 4. In addition, this embodiment also adds a quick-release connector 5. The pump body 2 and the circulation pipe 4 are connected to each other through the quick-release connector 5 to allow the medium to flow. In this embodiment, the radiator 3 is set separately on the support arm 101. Therefore, in order to facilitate the disassembly of the support arm 101 and the lamp holder 102, the quick-release connector 5 is installed between the radiator 3 and the circulation pipe 4. The quick-release connector 5 includes a male connector 51 and a female connector 52 suitable for mutual sealing connection, and the male connector 51 and the female connector 52 of the quick-release connector 5 are separated from each other to restrict the flow of the medium.

[0039] It is understood that the stage light in this embodiment adopts a traditional liquid cooling system in its heat dissipation system structure, which includes a heat absorption plate 1 in close contact with the light source 103 to absorb the heat generated by the light source, a pump body 2 as the power source for circulating the heat transfer medium, a radiator 3 to dissipate the absorbed heat to the outside, and a circulation pipe 4 to connect the pump body 2, the heat absorption plate 1 and the radiator 3 (the circulation pipe 4 runs through each heat dissipation fin of the radiator 3, but does not connect to the inside of the fins of the radiator 3), forming a closed circulation loop. The pump body 2 drives the heat transfer medium in the circulation pipe 4 to circulate between the heat absorption plate 1 and the radiator 3, thereby transferring the heat generated by the light source from the heat absorption plate to the radiator for dissipation to the outside. In addition, a quick-release connector 5 is added to the heat dissipation system. The quick-release connector 5 is located at the connection between the pump body 2 and the circulation pipe 4. When connection is needed, the pump body 2 and the circulation pipe 4 can be connected via the quick-release connector 5, allowing the heat transfer medium to flow within them. When disassembly is needed, the pump body 2 and the circulation pipe 4 can be separated by operating the quick-release connector 5, which simultaneously restricts the outflow of the heat transfer medium and prevents outside air from entering the medium pipe. When the stage lights are working, the light source 103 generates heat. The heat-absorbing plate 1 is in close contact with the light source 103, efficiently absorbing the heat generated by the light source. The pump body 2 starts, driving the heat transfer medium in the circulation pipe 4 to flow. The heated heat transfer medium flows out from the heat-absorbing plate 1, through the circulation pipe 4, and to the radiator 3. In the radiator 3, the heat transfer medium releases the absorbed heat into the surrounding environment. The cooled heat transfer medium continues to flow in the circulation pipe 4 and returns to the pump body 2, then flows back to the heat-absorbing plate 1, forming a closed loop. When maintenance or component replacement of the heat dissipation system is required, the quick-release connector can be used to quickly separate the pump body 2 from the circulation pipe 4. During separation, the quick-release connector restricts the outflow of the heat transfer medium through its internal sealing mechanism, preventing medium leakage and air from entering the piping system. After maintenance or replacement is completed, the quick-release connector can be used again to quickly reconnect the separated component to the circulation pipe 4. After connection, the quick-release connector opens the fluid passage, allowing the heat transfer medium to continue circulating. By introducing quick-release connectors, the disassembly and installation of each component of the heat dissipation system can be carried out without complicated tools and operations, greatly shortening maintenance time, reducing maintenance difficulty, and improving the convenience and efficiency of stage lighting heat dissipation system maintenance. When separated, the quick-release connectors can restrict the outflow of heat transfer medium and prevent air from entering. Therefore, after reconnection, there is no need to perform tedious vacuuming and airtightness testing, simplifying the maintenance process and avoiding the tedious vacuuming and airtightness testing required after disassembly and assembly of traditional liquid cooling systems. Therefore, this utility model enables the disassembly and assembly of each component of the stage lighting heat dissipation system to be carried out without complicated operations, shortening maintenance time and reducing maintenance difficulty, which helps to improve the convenience and efficiency of stage lighting heat dissipation system maintenance. At the same time, after the heat dissipation system is disassembled, it can restrict the outflow of heat transfer medium and prevent the entry of outside air, thus avoiding the tedious steps of vacuuming and airtightness testing required after the heat dissipation system is disassembled, simplifying the maintenance process.

[0040] Optionally in one embodiment, the male connector 51 and the female connector 52 are respectively sealed and fitted onto the interface between the circulation pipe 4 and the pump body 2. Each of the male connector 51 and the female connector 52 is equipped with a self-sealing valve. When the male connector 51 and the female connector 52 are connected, the self-sealing valve opens; when they are separated, the self-sealing valve closes. When connection is required, the male connector 51 and the female connector 52 are mated together, which opens the internal self-sealing valve, allowing the medium to flow between the circulation pipe 4 and the pump body 2. When disassembly is required, the male connector 51 and the female connector 52 are separated, and the self-sealing valve automatically closes, preventing medium leakage. This achieves efficient connection and disassembly of the quick-release connector 5, while ensuring that the internal medium does not leak and external air does not enter the pipeline during connection and disassembly. This eliminates the need for complex vacuuming and airtightness testing steps, reduces the complexity and cost of heat dissipation system maintenance, improves maintenance efficiency, and simplifies installation and maintenance procedures. Specifically, the self-sealing valves inside the male connector 51 and the female connector 52 are resilient valves. Utilizing the elastic characteristics of the resilient valves, they achieve automatic opening and closing when the male connector 51 and the female connector 52 are connected and separated. When the male connector 51 and the female connector 52 are connected, the mating of the two overcomes the elastic force of the resilient valve, opening it and allowing the medium to flow. When the male connector 51 and the female connector 52 are separated, the resilient valve closes under its own elastic force, preventing the medium from flowing out and the outside air from entering. By using resilient valves as self-sealing valves, their elastic characteristics can reliably achieve the self-sealing function, ensuring the system's sealing performance during quick-disassembly operations, further simplifying the maintenance process and reducing maintenance costs.

[0041] Optionally, the quick-release connector 5 described above can also directly adopt the existing direct-push fluid connector. The existing direct-push fluid connector also consists of male and female parts, each with a self-sealing elastic valve. The advantage of using a direct-push fluid connector is that during connection, the two ends of the connector can be directly pushed together to achieve fluid conduction. During disassembly, the two ends of the connector can be directly separated to stop fluid transmission, achieving a more convenient quick-release connector form and improving the efficiency of connection and disassembly. Therefore, using a direct-push fluid connector as the quick-release connector 5 simplifies the connection and disassembly process, improves work efficiency, and makes the maintenance of the stage lighting's heat dissipation system more convenient and faster. Direct-push fluid connectors have been widely proven in the industrial field, exhibiting better stability and durability. The quick-release connector 5 in this embodiment directly selects a standardized direct-push fluid connector, which simplifies design and improves reliability.

[0042] In one embodiment, a universal joint 6 is pivotally connected between the support arm 101 and the lamp head 102. The radiator 3 is mounted on the support arm 101, and the circulation pipe 4 passing through the radiator 3 is connected to the inside of the universal joint 6 and connected to the pump body 2 through the universal joint 6. With the above structure, when the lamp head 102 rotates or its angle is adjusted relative to the support arm 101, the universal joint 6 allows the circulation pipe 4 to rotate accordingly, thereby avoiding twisting or jamming caused by rigid pipes. The heat transfer medium can still flow inside the universal joint 6, ensuring that the medium in the circulation pipe 4 can circulate into and out of the radiator 3, ensuring the normal operation of the heat dissipation system. This solves the problem of limited heat dissipation and equipment structure caused by the inability of the pipes to freely follow the stage lamp head when it rotates, tilts, or swings horizontally at multiple angles. The universal joint 6 can achieve multi-degree-of-freedom rotation of the lamp head 102 while ensuring that the pipes are leak-free. Regarding the specific structure of the universal pipe joint 6, it includes a fixed sleeve 61 and a rotating sleeve 62. The fixed sleeve 61 is fitted onto the rotating sleeve 62, and the fixed sleeve 61 and the rotating sleeve 62 are rotatably and sealingly connected to each other. During installation, the fixed sleeve 61 is fitted into the pivot shaft 104 between the support arm 101 and the lamp holder 102, and the rotating sleeve 62 is fitted onto the bracket of the lamp holder 102. During operation, the heat transfer medium of the circulation pipe 4 can flow to the pump body 2 through the fixed sleeve 61 and the rotating sleeve 62. While the rotating sleeve 62 and the fixed sleeve 61 maintain fluid communication and prevent leakage, the lamp holder can also rotate normally around the pivot shaft 104.

[0043] Optionally, the fixed sleeve 61 and the rotating sleeve 62 in the structure of the universal pipe joint 6 described above can also be integrally formed during production.

[0044] Alternatively, the aforementioned universal pipe connector 6 can also directly adopt a conventional fluid rotary connector. The conventional fluid rotary connector is a commonly used type of universal joint in industry, combining fluid sealing and rotation functions. Its two ends are also divided into a fixed sleeve and a rotating sleeve. The fluid rotary connector is located at the pivot point between the support arm 101 and the lamp holder 102, allowing the lamp holder 102 to rotate on the support arm 101 while also sealing the heat dissipation medium. Fluid rotary connectors have been widely validated in industrial applications, exhibiting better stability and durability. In this embodiment, the universal pipe connector 6 directly uses a standardized fluid rotary connector, simplifying design and improving reliability.

[0045] In one embodiment, a quick-release connector 5 is connected between the circulation pipe 4 running through the radiator 3 and the universal joint 6. This allows for the flow of medium between the circulation pipe 4 and the universal joint 6, and also allows for separation and restriction of medium outflow. In other words, in the pipe section “radiator 3 – (circulation pipe 4) – universal joint 6”, an additional detachable quick-release connector 5 is provided. This structure is equivalent to connecting the quick-release connector 5 to the universal joint 6, forming a combination, essentially connecting a conventional push-type fluid connector to a conventional fluid rotary connector. This allows for easy disconnection from the radiator 3 on the universal joint 6 side, facilitating quick and easy disconnection of the pipe connection between the radiator 3 and the universal joint 6 during maintenance of the cooling system or disassembly of the lamp holder. Furthermore, the self-sealing valve within the quick-release connector 5 prevents leakage of the medium fluid within the pipe, facilitating subsequent maintenance.

[0046] In one embodiment, the circulation pipe 4 between the quick-release connector 5 and the universal pipe connector 6 is a bent pipe 41, allowing the circulation pipe 4 to adapt to the spatial arrangement of the universal pipe connector 6 and the radiator 3, ensuring that the circulation pipe 4 can be smoothly connected between the universal pipe connector 6 and the radiator 3. The circulation pipe 4 between the radiator 3 and the quick-release connector 5 is a multi-section bent pipe 42, to match the circulation pipe layout requirements inside the radiator 3.

[0047] In one embodiment, the radiator 3 includes a heat dissipation fin assembly 31 and a fan 32. A circulation pipe 4 is connected in series with the heat dissipation fin assembly 31, and the air outlet of the fan 32 corresponds to the heat dissipation gap of the heat dissipation fin assembly 31. During operation, the heat transfer medium in the circulation pipe 4 is transferred to the heat dissipation fin assembly 31 through the pipe wall, while the airflow generated by the fan 32 continuously flows through the gaps between the heat dissipation fins in the heat dissipation fin assembly 31. The flowing air carries the heat of the heat dissipation fin assembly 31 out of the stage light, thereby achieving the heat dissipation effect of the stage light source.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
