Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and specifically relates to a stage lamp. Background Technology

[0002] Existing stage lights often rely on internally configured heat dissipation modules for heat dissipation. The effectiveness of their heat dissipation depends entirely on the heat dissipation performance of the heat dissipation module. Currently, stage lights lack external heat dissipation design, which means that when the heat dissipation module ages or fails, it can only be replaced as a whole, or upgraded when it is necessary to improve its heat dissipation effect. This results in high equipment costs, and in case of sudden heat dissipation failure, the core of the stage light may be damaged and burned out, which seriously reduces the reliability and lifespan of the stage light.

[0003] Furthermore, existing stage lighting sometimes requires the rapid generation of large amounts of white mist to create specific stage effects during performances. However, traditional smoke machines or atomizing devices are typically bulky, require additional power supplies and control systems, have low integration with stage lighting, and are inconvenient to operate. At the same time, the white mist effects produced by these devices may not be natural enough or last long enough to meet the demands of high-standard stage performances. Therefore, how to effectively solve the heat dissipation problem of stage lighting while simultaneously meeting the need for rapid white mist generation in stage performances is a pressing issue in the field of stage lighting technology.

[0004] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0005] The purpose of this utility model is to provide a stage light that solves the problems of limited heat dissipation, high maintenance costs, unnatural stage fog effects, and low integration of existing stage lights. It achieves a synergistic effect between heat dissipation and stage effect creation, thereby improving the practicality and functionality of the stage light.

[0006] In a first aspect, the present invention provides a stage light, including an illumination part having a heat dissipation hole, and an external heat dissipation device, which is mounted on the illumination part and located on one side of the heat dissipation hole; the external heat dissipation device includes a cavity, the cavity having an opening on its upper side and being open at the front and communicating with the heat dissipation hole, and dry ice being placed in the cavity through the upper opening to absorb the heat output from the heat dissipation hole.

[0007] The stage light provided by this utility model highly integrates the heat dissipation function of the stage light with the function of generating stage fog effect. It not only achieves efficient heat dissipation and avoids overheating of the lighting unit, but also generates a large amount of fog in a very short time, which meets the needs of stage performance.

[0008] Furthermore, louvers communicating with the outside are provided on both the left and right sides of the cavity.

[0009] Furthermore, the opening and closing size of the venetian blinds is adjustable.

[0010] Furthermore, an observation window capable of penetrating the cavity is provided on the rear side of the cavity.

[0011] Furthermore, a fan is provided at the upper opening of the cavity, the fan facing the heat dissipation hole, and the fan is used to blow air to the dry ice placed in the cavity.

[0012] Furthermore, the fan is rotatably connected to the cavity and can cover the upper opening of the cavity.

[0013] Furthermore, the external heat dissipation device is detachably connected to the lighting unit.

[0014] Furthermore, the external heat dissipation device also includes a clamping part fixedly connected to the cavity, the clamping part being used to connect to the lighting part so that the external heat dissipation device is mounted on the lighting part.

[0015] Furthermore, the clamping part is made of an elastic material and has a notch for the lighting part to pass through so that the clamping part can be clamped and fixed to the lighting part.

[0016] Furthermore, the clamping part is made of silicone or rubber material.

[0017] As described above, this utility model's stage light, by installing an external heat dissipation device on the lighting unit and placing dry ice in the cavity of the external heat dissipation device, allows the dry ice to absorb the heat discharged from the heat dissipation holes of the lighting unit through sublimation, thereby achieving rapid cooling of the lighting unit. This design effectively solves the problems of limited heat dissipation effect and high maintenance cost of existing stage light internal heat dissipation modules, avoids the risk of damage to core components due to heat dissipation failure, and significantly improves the reliability and service life of the stage light. At the same time, the heat generated by the lighting unit accelerates the sublimation of dry ice, producing a large amount of white mist in a very short time, meeting the need to quickly create specific effects in stage performances, and overcoming the shortcomings of traditional smoke machines such as large size, low integration, and inconvenient operation. This solution combines heat dissipation with stage effect creation, with the two complementing each other, achieving functional innovation and optimization, and providing an efficient, convenient, and multifunctional solution in the field of stage lighting technology.

[0028] Reference Appendix Figure 1 and attached Figure 2 This utility model provides a stage light, including an illumination unit 100, which is provided with heat dissipation holes 110, and an external heat dissipation device 200. The external heat dissipation device 200 is installed on the illumination unit 100 and located on one side of the heat dissipation holes 110. The external heat dissipation device 200 includes a cavity 210, which has an opening on its upper side and is open at the front and communicates with the heat dissipation holes 110. Dry ice is placed in the cavity 210 through the upper opening to absorb the heat output from the heat dissipation holes 110. When the illumination unit 100 is working, it generates a large amount of heat. The dry ice absorbs the heat of the illumination unit 100 quickly through sublimation, thereby rapidly cooling the illumination unit 100 and preventing it from overheating. At the same time, the heat of the illumination unit 100 also accelerates the sublimation of the dry ice, thereby generating a large amount of white mist in a very short time to meet the needs of stage performances. The two functions complement each other.

[0029] This application cleverly combines the heat dissipation function of the stage light with the generation of stage fog effect by introducing an external heat dissipation device 200. This not only effectively solves the heat dissipation problem of the stage light, but also provides a highly integrated and easy-to-operate fog generation solution, greatly improving the functionality and practicality of the stage light.

[0030] The core of the stage light proposed in this application lies in the integrated design of heat dissipation and stage effect generation. The lighting unit 100 is the core light-emitting component of the stage light, generating a significant amount of heat during operation. The heat dissipation holes 110 are channels on the lighting unit 100 used to dissipate the heat generated during operation. The external heat dissipation device 200 is a key innovation of this application; it is a module independent of the lighting unit 100, which can be installed on the lighting unit 100 and works in conjunction with the heat dissipation holes 110. The cavity 210 is the main component of the external heat dissipation device 200, and its interior is used to contain dry ice. Dry ice, i.e., solid carbon dioxide, sublimates directly into gaseous carbon dioxide at room temperature and pressure, a process that absorbs a large amount of heat.

[0031] Specifically, the lighting unit 100, as the core component of the stage light, generates significant heat during prolonged operation. To effectively dissipate this heat, the lighting unit 100 is equipped with heat dissipation holes 110. These heat dissipation holes 110 can be simple openings or designs with airflow guiding structures, such as honeycomb mesh or strip grilles, to increase the heat dissipation area and guide hot airflow. The size and number of heat dissipation holes 110 can be adjusted according to the power and heat dissipation requirements of the lighting unit 100. For example, for high-power stage lights, multiple larger heat dissipation holes 110 can be provided to ensure rapid heat dissipation.

[0032] The external heat dissipation device 200 is designed to be mounted on the lighting unit 100 and located on one side of the heat dissipation hole 110. This mounting method can be a fixed connection, such as by screws or clips, or a detachable connection for easy maintenance and replacement. The core of the external heat dissipation device 200 is the cavity 210. The cavity 210 can be made of various materials, such as metal (e.g., aluminum alloy) or high-temperature resistant plastic, to ensure its structural stability and durability. An opening is provided on the upper side of the cavity 210; this opening can be rectangular, circular, or any shape that facilitates the placement of dry ice. The front of the cavity 210 is open and communicates with the heat dissipation hole 110. This communication ensures that the heat dissipated by the lighting unit 100 can directly enter the cavity 210 and exchange heat with the dry ice inside. For example, the front of the cavity 210 can be designed as an interface that matches the shape of the heat dissipation hole 110 to achieve a tight connection and reduce heat loss.

[0033] When the lighting unit 100 operates and generates heat, this heat is dissipated through the heat dissipation holes 110 and enters the cavity 210 of the external heat dissipation device 200. Dry ice placed inside the cavity 210 absorbs this heat and rapidly sublimates. The sublimation process of dry ice is an endothermic process, efficiently removing the heat generated by the lighting unit 100 and thus providing rapid cooling. For example, when the temperature of the lighting unit 100 reaches a preset threshold, the sublimation rate of the dry ice will significantly accelerate, absorbing more heat in a short time and effectively preventing damage to the lighting unit 100 due to overheating. Simultaneously, the heat dissipated by the lighting unit 100 also accelerates the sublimation of the dry ice, generating a large amount of white mist in a very short time. This white mist can be discharged from the open front of the cavity 210 to create special effects required for stage performances. This design allows the stage light to achieve efficient heat dissipation while simultaneously generating stage effects; the two functions complement each other, achieving a high degree of functional integration and optimization.

[0034] The stage light of this application achieves efficient heat dissipation by combining an external heat dissipation device 200 with the heat dissipation holes 110 of the lighting unit 100. When the lighting unit 100 generates a large amount of heat during operation, this heat is dissipated through the heat dissipation holes 110. The front of the cavity 210 of the external heat dissipation device 200 is open and communicates with the heat dissipation holes 110, allowing the heat dissipated by the lighting unit 100 to directly enter the cavity 210. The dry ice placed inside the cavity 210 absorbs this heat and then rapidly sublimates. Dry ice sublimation is a strong endothermic process that can quickly remove the heat from the lighting unit 100, thereby achieving rapid cooling of the lighting unit 100 and effectively preventing performance degradation or damage to the lighting unit 100 due to overheating.

[0035] Meanwhile, the heat discharged from the lighting unit 100 not only provides the thermal energy required for the sublimation of the dry ice but also accelerates the sublimation rate. This accelerated sublimation allows the dry ice to generate a large amount of white mist in a very short time. This white mist is discharged from the open front part of the cavity 210 and can quickly diffuse into the stage area, creating a rich stage atmosphere and meeting the immediate need for white mist effects in stage performances. Thus, the stage light of this application cleverly combines the seemingly independent functions of heat dissipation and stage effect generation, forming a mutually reinforcing and complementary system. The heat of the lighting unit 100 is effectively utilized, solving the heat dissipation problem and providing energy for the rapid generation of white mist. This ensures the normal operation and extended lifespan of the stage light while greatly enhancing the visual effects and flexibility of stage performances.

[0036] The stage light proposed in this application has significant advantages and innovations compared to existing technologies. Traditional stage lights mainly rely on internal heat dissipation modules for cooling, and their cooling effect is often limited by the performance of the modules themselves. Moreover, when it is necessary to improve the cooling effect or when the modules fail, the only solution is to replace or upgrade the entire system, which is costly and inefficient. In addition, traditional stage fog generation equipment is usually independent, bulky, inconvenient to operate, and has low integration with the stage light.

[0037] This application highly integrates the heat dissipation function of the stage lights with the generation function of the stage fog effect. The external heat dissipation device 200 is installed on the lighting unit 100 and uses the waste heat generated by the lighting unit 100 during operation to accelerate the sublimation of dry ice. This design not only achieves efficient heat dissipation and avoids overheating of the lighting unit 100, but also generates a large amount of fog in a very short time, meeting the needs of stage performances.

[0038] Compared with existing technologies, the advantages of this application are as follows: First, significantly improved heat dissipation efficiency. Utilizing the strong heat absorption properties of dry ice sublimation, the heat from the lighting unit 100 can be quickly removed, achieving rapid cooling and effectively extending the lifespan of the stage light. Second, high functional integration. Combining heat dissipation with white mist generation reduces the number and complexity of stage equipment, improving the overall integration and ease of operation of the stage light. Third, high resource utilization. The waste heat generated by the lighting unit 100 is effectively utilized and converted into energy for white mist generation, achieving energy recycling and reducing operating costs. Finally, superior stage effect. The white mist effect generated by dry ice sublimation is natural and rapid, better meeting the needs of high-standard stage performances. This innovative design makes the stage light of this application surpass existing technologies in terms of functionality, economy, and stage effect, bringing significant progress to the field of stage lighting technology.

[0039] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 Both sides of the cavity 210 are equipped with louvers 220 that communicate with the outside world, thereby controlling the position and direction of the white fog generation.

[0040] Specifically, the louvers 220 can be understood as a structure with adjustable blades, located on the left and right sides of the cavity 210 and connected to the external environment. The blades of these louvers 220 can be adjusted to different opening angles to change the path and direction of the white mist flowing from inside the cavity 210 to the outside. The connection to the outside means that when the louvers 220 are open, they allow the white mist generated inside the cavity 210 to freely escape into the stage space. The purpose is to provide more flexible control over the white mist effects for stage performances.

[0041] The solution of this application, by setting louvers 220 on the left and right sides of the cavity 210, effectively guides and limits the flow direction and diffusion range of the white mist generated by the sublimation of dry ice when it exits the cavity 210. Specifically, when the lighting unit 100 operates and generates heat, the dry ice in the cavity 210 sublimates rapidly, generating a large amount of white mist. This white mist creates a certain pressure inside the cavity 210 and seeks to exit through the opening. By adjusting the opening degree of the louvers 220 on the left and right sides, the white mist can be controlled to exit from one side or both sides at a specific angle and intensity. For example, when the left louver 220 is partially open and the right louver 220 is completely closed, the white mist will mainly exit from the left side and diffuse in a specific direction; and vice versa. Thus, the position and direction of the white mist generation can be precisely controlled according to stage requirements.

[0042] Through the aforementioned technical solution, this application enables precise control over the position and direction of the white fog generated by stage lights. Compared to basic solutions that can only generate white fog but cannot control its flow, the additional technical features of this application give stage lights greater flexibility and operability in creating atmosphere and achieving specific visual effects. This greatly enhances the artistic expressiveness of stage performances, allowing the white fog effect to better complement the plot and scene, thereby providing the audience with a more immersive experience.

[0043] In some embodiments, the opening size of the veneer 220 is adjustable, thereby controlling the amount of white fog generated.

[0044] Specifically, the adjustable opening size of the venetian blinds 220 means that the angle or opening of the slats can be adjusted according to actual needs. The venetian blinds 220 can be understood as a structure composed of multiple parallel slats, which can rotate around their respective axes or translate as a whole to change the size of the gaps between them. In practical applications, the opening size of the venetian blinds 220 can be controlled by a manual adjustment mechanism, an electric actuator, or an intelligent control system. For example, the angle of the slats can be changed via a knob, lever, remote control, or preset program, thereby achieving precise control of the airflow channel area. The aim is to provide a flexible mechanism to adapt to the diverse requirements of white mist effects in stage performances.

[0045] The solution in this application allows for adjustable opening and closing of the louvers 220, directly influencing the rate and total amount of white mist escaping from the cavity 210. When the opening and closing of the louvers 220 is adjusted to a smaller size, the escape path of the white mist is limited, thereby reducing the amount of white mist escaping per unit time, resulting in a thinner or more localized white mist effect. Conversely, when the opening and closing of the louvers 220 is adjusted to a larger size, the escape path of the white mist increases, thereby increasing the amount of white mist escaping per unit time, resulting in a denser or more diffused white mist effect. It is precisely because of this adjustability that the stage lights can flexibly control the concentration and coverage of the white mist according to specific performance scenes and artistic needs.

[0046] Through the aforementioned technical solutions, stage lights can not only control the position and direction of the white fog generation, but also achieve precise control over the amount of white fog generated. This gives stage lights greater flexibility and expressiveness in creating atmosphere, allowing them to adjust the density of the white fog in real time according to the plot development, musical rhythm, or specific scenes, thereby creating richer and more varied visual effects and greatly enhancing the artistic appeal and entertainment value of stage performances.

[0047] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 An observation window 230 is provided on the rear side of the cavity 210, which allows the user to see through the cavity 210 and directly view the remaining amount of dry ice.

[0048] Specifically, the observation window 230 refers to a transparent or semi-transparent structure located on the rear side of the cavity 210. Its material can be glass, plexiglass, polycarbonate, or other materials with good light transmittance. This observation window 230 is designed to allow light to pass through, enabling external observers to clearly see the actual state and remaining amount of dry ice inside the cavity 210. Its purpose is to provide users with a convenient and intuitive way to monitor dry ice consumption, allowing for timely replenishment and ensuring the normal operation of the stage lights and the expected stage effects.

[0049] The solution in this application provides an observation window 230 on the rear side of the cavity 210, allowing the user to directly observe the amount of dry ice inside without opening the cavity 210. When the lighting unit 100 is operating, the dry ice sublimates within the cavity 210, gradually reducing its volume. The presence of the observation window 230 allows the user to monitor the dry ice consumption in real time, enabling them to anticipate and replenish the ice before it runs out. This avoids sudden interruptions in cooling or the formation of white fog due to the depletion of dry ice, ensuring the continuity and stability of the stage lighting function.

[0050] Through the above technical solution, users can intuitively and conveniently grasp the remaining dry ice in the cavity 210, significantly improving the operability and maintenance convenience of the stage lights. Compared with solutions without an observation window, this application effectively solves the problem of difficulty in judging the remaining dry ice, avoiding the risk of stage effect interruption or equipment overheating due to the depletion of dry ice, thereby ensuring the smooth progress of stage performances and the long-term stable operation of the stage lights. This design not only enhances the user experience but also indirectly extends the service life of the equipment, demonstrating significant practical value and technological advancement.

[0051] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 A fan 240 is provided at the upper opening of the cavity 210. The fan 240 faces the heat dissipation hole 110 and is used to blow air to the dry ice placed in the cavity 210.

[0052] Specifically, a fan 240 is installed at the upper opening of the cavity 210, facing the heat dissipation hole 110. The fan 240 is used to supply air to the dry ice placed inside the cavity 210. The fan 240 is positioned at the upper opening of the cavity 210, and its main function is to supply air to the dry ice inside the cavity 210. The airflow direction of the fan 240 is set towards the heat dissipation hole 110, which means that the airflow not only acts on the surface of the dry ice, but may also guide the cold airflow generated by the sublimation of the dry ice to mix better with the hot airflow discharged from the heat dissipation hole 110, or directly accelerate the heat exchange between the dry ice and the heat. By supplying air to the dry ice, the airflow on the surface of the dry ice can be accelerated, thereby promoting the sublimation process of the dry ice. This helps to absorb the heat of the lighting unit 100 more quickly and produce more white mist. In practical applications, the fan 240 can be an axial fan, a centrifugal fan, or other types of air supply device, and its size and power can be selected according to the heat dissipation requirements and white mist production requirements of the stage light. As a preferred embodiment, the fan 240 can be fixedly installed or have an adjustable angle to optimize the air delivery effect.

[0053] The solution of this application actively circulates air through a fan 240 positioned at the upper opening of the cavity 210 and oriented towards the heat dissipation hole 110, thereby supplying air to the dry ice placed within the cavity 210. When the fan 240 operates, the airflow it generates accelerates the airflow over the surface of the dry ice, carrying away the cold air layer generated by the sublimation of the dry ice. This allows the dry ice to continuously exchange heat with the surrounding air, significantly increasing the sublimation rate of the dry ice. Consequently, the dry ice can more quickly absorb the heat discharged from the lighting unit 100 through the heat dissipation hole 110, accelerating the cooling process of the lighting unit 100 and causing the dry ice to generate a large amount of white mist in a very short time. Simultaneously, the airflow direction of the fan 240 towards the heat dissipation hole 110 helps to effectively mix the cold airflow generated by the sublimation of the dry ice with the hot airflow discharged from the lighting unit 100, further optimizing the heat exchange efficiency and ensuring that the white mist can be effectively guided and diffused, meeting the needs of stage performances for immediate and abundant white mist.

[0054] Through the aforementioned technical solution, the sublimation rate of dry ice is significantly improved due to the active airflow of fan 240, resulting in faster cooling of the lighting unit 100 and effectively preventing overheating. More importantly, this solution ensures the generation of a large amount of white fog in a very short time, solving the problem of precise control over the amount and speed of white fog generation in traditional solutions, greatly enhancing the immediacy and visual effects of stage performances. Furthermore, the airflow from fan 240 can also provide some guidance to the diffusion direction and range of the white fog, further enhancing the practicality and flexibility of the stage lighting.

[0055] In some embodiments, the fan 240 is rotatably connected to the cavity 210 and can close over the upper opening of the cavity 210.

[0056] Specifically, the rotatable connection between the fan 240 and the cavity 210 means that the fan 240 is connected to the main body of the cavity 210 via one or more shafts, hinges, or other rotatable connecting mechanisms. This connection allows the fan 240 to rotate around one or more axes, thereby adjusting its position. The fan 240 can close into the upper opening of the cavity 210, meaning that when the fan 240 rotates to a specific position, its structure can form a closed or semi-closed state with the upper opening of the cavity 210, thus covering the opening. The purpose is to effectively close the upper opening of the cavity 210 when airflow is not required, reducing the contact between the dry ice and the outside air, thereby controlling the sublimation rate of the dry ice.

[0057] When air needs to be supplied to dry ice to accelerate its sublimation and produce white mist, fan 240 can be rotated to the air supply position, directing it towards the heat dissipation vent 110 and supplying air to the dry ice. The adjustable air supply angle allows for better control of heat dissipation and white mist generation efficiency. When white mist generation is not needed or needs to be paused, fan 240 can be rotated to the closed position, thus partially closing the upper opening of cavity 210 (the fan can still supply air even when closed; the airflow will blow vertically downwards towards the dry ice, while the white mist flows out from the left and right sides. Therefore, the adjustable angle of fan 240 allows for adjustment of the airflow direction). This design allows fan 240 to not only supply air but also function as a cover, effectively managing the opening state of cavity 210. Thus, the sublimation process of dry ice can be effectively controlled, avoiding unnecessary dry ice consumption.

[0058] Through the above technical solution, the dry ice management efficiency of the stage lights is significantly improved. The rotating connection and closing function of the fan 240 allows users to flexibly control the sublimation rate of the dry ice according to actual needs, effectively reducing dry ice waste. Furthermore, when dry ice needs to be added or replaced, the fan 240 can be easily rotated open, providing a convenient operating channel and improving the practicality and maintenance convenience of the stage lights. This design not only optimizes the control of white fog generation but also extends the lifespan of the dry ice and reduces operating costs.

[0059] In some embodiments, the external heat dissipation device 200 is detachably connected to the lighting unit 100. For example, this connection can take various forms such as snap-fit, bolt, magnetic, or plug-in connections. The purpose is to improve the flexibility and maintainability of the stage light.

[0060] For details, please refer to the appendix. Figure 1 and attached Figure 2 The external heat dissipation device 200 also includes a clamping part 250 fixedly connected to the cavity 210. The clamping part 250 is used to connect to the lighting part 100 so that the external heat dissipation device 200 is mounted on the lighting part 100.

[0061] The clamping part 250 can be understood as a structural component used to securely fix the external heat dissipation device 200 to the lighting unit 100. It is fixedly connected to the cavity 210, for example by welding, bolting, riveting, or integral molding, to ensure that the clamping part 250, as a component of the external heat dissipation device 200, will not loosen or fall off during installation and use. The main purpose of the clamping part 250 is to provide a convenient and reliable connection method, allowing the external heat dissipation device 200 to be easily installed onto or removed from the lighting unit 100 according to actual needs, thereby achieving a detachable connection between the external heat dissipation device 200 and the lighting unit 100.

[0062] The solution of this application provides a dedicated, structured connection interface for the external heat dissipation device 200 by setting a clamping part 250. When the external heat dissipation device 200 needs to be installed on the lighting unit 100, the clamping part 250 can directly connect with the lighting unit 100, for example, through snap-fit, clamping, or threaded engagement. This design makes the installation process simple and intuitive, allowing users to complete the installation without complicated tools or operations. At the same time, the fixed connection characteristics of the clamping part 250 ensure the stability of the external heat dissipation device 200 in the working state, preventing it from falling off due to vibration or external force, thus effectively solving the problem of how to ensure the stable and convenient installation and removal of the external heat dissipation device 200.

[0063] Through the above technical solution, the connection method between the external heat dissipation device 200 and the lighting unit 100 has been clarified and optimized. The introduction of the clamping part 250 not only simplifies the installation and disassembly process of the external heat dissipation device 200 and improves the convenience of operation, but also enhances the stability of the connection, ensuring that the external heat dissipation device 200 can reliably adhere to the lighting unit 100 during stage lighting operation, effectively absorbing heat and generating white mist, avoiding the impact on the normal operation of the stage lighting and the presentation of stage effects due to unstable connection. This significantly improves the practicality of the stage lighting and the user experience.

[0064] In some preferred embodiments, the clamping part 250 can be designed as a U-shaped or C-shaped clamp structure, the inner dimensions of which match the outer dimensions of the lighting part 100. When the external heat dissipation device 200 needs to be installed, this clamp structure can be directly fitted onto a specific position of the lighting part 100 and fixed by bolts, clips, or elastic deformation. For example, the clamping part 250 can be made of a metal or engineering plastic with a certain degree of elasticity, and its interior is provided with an anti-slip pad to increase the friction when in contact with the lighting part 100, further improving the stability of the connection. When disassembly is required, the external heat dissipation device 200 can be easily removed from the lighting part 100 simply by releasing the corresponding fixing mechanism, thereby achieving quick replacement or maintenance.

[0065] In some embodiments, reference is made to the appendix. Figure 2 The clamping part 250 is made of elastic material and has a notch. The notch is used to allow the lighting part 100 to pass through so that the clamping part 250 is clamped and fixed on the lighting part 100. The clamping part 250 deforms to enlarge the notch so that the lighting part 100 can pass through. Finally, the clamping part 250 returns to its original shape and is clamped and fixed on the lighting part 100.

[0066] Specifically, the clamping part 250 is designed to be made of a material with a certain degree of elasticity, such as silicone, rubber, or other polymer elastomers. This elastic material allows the clamping part 250 to deform under external force and return to its original shape after the force is released. The notch provided on the clamping part 250 is slightly smaller than the corresponding size of the lighting part 100 in its natural state to ensure a tight fit during clamping. When an external heat dissipation device 200 needs to be installed, external force is applied to the clamping part 250, causing it to elastically deform and thus widening the notch so that the lighting part 100 can pass through smoothly. Once the lighting part 100 has passed through and reached the predetermined position, the external force is released, and the clamping part 250 returns to its original shape due to its elasticity, thereby tightly clamping and fixing it to the lighting part 100. This design aims to provide a convenient and reliable connection method.

[0067] The solution proposed in this application solves the problems of inconvenient installation or unstable fixation that may exist in traditional clamping methods by designing the clamping part 250 as an elastic material and setting a notch. Due to the elastic properties of the clamping part 250, it can adapt to the size of the lighting part 100 through controllable deformation, thereby achieving quick and stable installation. When the lighting part 100 is pushed into the notch, the clamping part 250 undergoes elastic deformation, and the notch temporarily expands; once the lighting part 100 is in place, the elastic restoring force of the clamping part 250 will tightly hug the lighting part 100, forming a reliable clamping fixation. This adaptive clamping mechanism allows the external heat dissipation device 200 to be easily disassembled and installed with the lighting part 100, while ensuring the stability of the connection.

[0068] Through the above technical solution, the connection between the external heat dissipation device 200 and the lighting unit 100 becomes more convenient and reliable. The introduction of the elastic clamping part 250 allows users to easily install and remove the external heat dissipation device 200 without the need for additional tools, significantly improving operational convenience. At the same time, the self-recovering properties of the elastic material ensure a tight clamping fit, effectively avoiding the risk of the external heat dissipation device 200 falling off or shifting position due to loose connection, thereby ensuring the stability and safety of the stage light during operation.
