Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting technology, specifically a waterproof stage light. Background Technology
[0002] Waterproof stage lights are professional stage lighting equipment designed for outdoor performances or humid environments. Their structural design and functional characteristics are specially optimized to meet the needs of use in harsh weather or special scenarios. Waterproof stage lights are widely used in outdoor performances, music festival stages, theme park light shows, waterfront light shows, water performances, and beach performances. These scenarios typically require lighting fixtures with excellent waterproof performance and stable lighting effects to ensure the smooth running of the performance and a good audience experience.
[0003] The main structure of a waterproof stage light includes a base, a U-shaped bracket (or arm), the light fixture, and related sealing and waterproofing components. Existing waterproof stage lights are generally designed with a fully sealed structure to prevent moisture from entering the fixture.
[0004] However, during use, it was found that because the stage light is in a completely sealed state, it can only dissipate heat through internal circulation. Since the heat is constantly circulating inside the sealed space of the stage light and cannot be expelled, the heat dissipation effect is poor, which is not conducive to the long-term use of the stage light. Therefore, we have proposed a waterproof stage light to effectively solve the above-mentioned drawbacks. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof stage light to solve the problem mentioned in the background art that heat circulates continuously in the sealed space inside the stage light and cannot be dissipated, resulting in poor heat dissipation and making it unsuitable for long-term use of the stage light.
[0006] This utility model is achieved through the following technical solution: a waterproof stage light, including a base, the top of the base is rotatably connected to a U-shaped bracket via a vertical axis, the inner side of the U-shaped bracket is rotatably connected to a lamp via two horizontal axes, the U-shaped bracket is provided with a U-shaped ventilation cavity inside, and each horizontal axis is provided with a connecting hole to allow the U-shaped ventilation cavity to communicate with the inside of the lamp.
[0007] The U-shaped ventilation cavity is equipped with a heat dissipation component. Ventilation openings are provided on the left and right sides of the U-shaped support to allow the U-shaped ventilation cavity to communicate with the outside. Sealing components adapted to the ventilation openings are provided on the left and right sides of the U-shaped support.
[0008] Optionally, the outer surface of the lamp is evenly distributed with a plurality of first heat dissipation fins, and the outer surface of the U-shaped bracket is evenly distributed with a plurality of second heat dissipation fins.
[0009] Optionally, the heat dissipation assembly includes an intake fan installed at one end of the U-shaped ventilation cavity and an exhaust fan installed at the other end of the U-shaped ventilation cavity.
[0010] Optionally, the intake fan, exhaust fan, connecting holes, and ventilation openings are arranged along the same axis.
[0011] Optionally, the sealing assembly includes a sealing plate, which is a semi-enclosed structure that is movably sleeved on the U-shaped bracket;
[0012] Limiting notches are provided on both the front and rear sides of the sealing plate, and locking knobs corresponding to each limiting notch are provided on the U-shaped bracket.
[0013] Optionally, the opening end of the limiting notch is set to be larger on the outside and smaller on the inside.
[0014] Compared with the prior art, this utility model provides a waterproof stage light with the following advantages:
[0015] This invention, by incorporating a U-shaped ventilation cavity, connecting holes, a heat dissipation component, a vent, and a sealing component, ensures a completely sealed interior for use in rainy or humid outdoor environments. This prevents external moisture from entering the stage lamp, resulting in good waterproofing. Furthermore, when the stage lamp is completely sealed, the internal air circulates within the U-shaped ventilation cavity and the lamp itself, creating a longer airflow path that facilitates heat exchange with the outside air, leading to better heat dissipation and extended use. In non-rainy or non-humid outdoor environments, the vent can be opened, allowing the U-shaped ventilation cavity to connect with the outside, enabling rapid heat dissipation from the stage lamp's interior.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 3 A waterproof stage light includes a base 1 that provides support for the equipment; the top of the base 1 is rotatably connected to a U-shaped bracket 2 via a vertical axis, and the U-shaped bracket 2 can rotate along the vertical axis; the inner side of the U-shaped bracket 2 is rotatably connected to a lamp 3 via two horizontal axes, and the lamp 3 can rotate along the horizontal axes. This is prior art and will not be described in detail here.
[0022] In this embodiment, the U-shaped bracket 2 has a U-shaped ventilation cavity 4 inside. When air flows in the U-shaped ventilation cavity 4, the flow path is relatively long, which helps to exchange heat with the outside air and thus facilitates heat dissipation inside the stage lamp. Furthermore, each horizontal axis is provided with a connecting hole 5 to allow the U-shaped ventilation cavity 4 to communicate with the inside of the lamp 3; therefore, when the stage lamp is in a fully sealed state, the air inside the stage lamp can circulate within the U-shaped ventilation cavity 4, the connecting hole 5, and the lamp 3.
[0023] In addition, a heat dissipation component 6 is installed inside the U-shaped ventilation cavity 4 to allow airflow within the cavity. Ventilation openings 7 are provided on the left and right sides of the U-shaped support 2 to connect the U-shaped ventilation cavity 4 with the outside environment, allowing air exchange between the cavity and the outside. Sealing components 8, adapted to the ventilation openings 7, are provided on the left and right sides of the U-shaped support 2, allowing the openings 7 to be opened or closed, thus enabling the stage light interior to be in a non-enclosed or fully enclosed state.
[0024] With the above structure, when used outdoors in rainy or humid environments, the sealing component 8 seals the vent 7, maintaining a completely sealed state inside the stage lamp. This prevents external moisture from entering the stage lamp, resulting in good waterproof performance. When the stage lamp is in a completely sealed state, the heat dissipation component 6 operates, driving the air inside the stage lamp to circulate within the U-shaped ventilation cavity 4 and the lamp fixture 3. This results in a longer airflow path, facilitating heat exchange with the outside air and improving heat dissipation, which is beneficial for the long-term use of the stage lamp.
[0025] When used outdoors in non-rainy or non-humid environments, the vent 7 can be opened, allowing the U-shaped ventilation cavity 4 to communicate with the outside. At this time, when the stage light is cooled by the heat dissipation component 6, the internal air can be exchanged with the outside air, thereby quickly dissipating the heat inside the stage light.
[0026] It should be added that the outer surface of the lamp 3 is evenly distributed with several first heat dissipation fins 9, and the outer surface of the U-shaped bracket 2 is evenly distributed with several second heat dissipation fins 10. When the stage lamp is in a fully enclosed state, the air circulates in the U-shaped ventilation cavity 4 and the lamp 3, and can enhance the heat exchange effect between the internal air and the outside air through each of the first heat dissipation fins 9 and each of the second heat dissipation fins 10.
[0027] The following is a description of heat dissipation component 6:
[0028] The heat dissipation assembly 6 includes an intake fan 601 installed at one end of the U-shaped ventilation cavity 4, and an exhaust fan 602 installed at the other end of the U-shaped ventilation cavity 4. When the stage light is in a closed state, the intake fan 601 and the exhaust fan 602 work simultaneously, which can accelerate the circulation speed of the internal air and significantly improve the heat dissipation effect. When the stage light is not in a closed state, the intake fan 601 can send outside air into the U-shaped ventilation cavity 4, while the exhaust fan 602 can send internal air to the outside, thereby exchanging internal air with outside air and improving heat dissipation efficiency.
[0029] In this embodiment, it should be noted that the intake fan 601, exhaust fan 602, each connecting hole 5, and each ventilation opening 7 are arranged along the same axis. This design allows the intake fan 601 and exhaust fan 602 to quickly draw outside air into the lamp 3 and simultaneously expel air from inside the lamp 3 when the ventilation opening 7 is open.
[0030] The sealing assembly 8 is described below:
[0031] The sealing assembly 8 includes a sealing plate 801, which is a semi-enclosed structure that is movably fitted onto the U-shaped bracket 2. This semi-enclosed structure prevents rainwater or moisture from easily entering the vent 7 when it is being sealed. Furthermore, the structure is simple and easy to assemble and disassemble. Limiting notches 802 are provided on both the front and rear sides of the sealing plate 801, and locking knobs 803 corresponding to each limiting notch 802 are provided on the U-shaped bracket 2. When the sealing plate 801 is fitted onto the U-shaped bracket 2, the locking knobs 803 can be engaged into the limiting notches 802. Tightening the locking knobs 803 locks the sealing plate 801 in place, preventing it from easily detaching from the U-shaped bracket 2. Furthermore, the opening end of the limiting notch 802 is wider on the outside and narrower on the inside, facilitating the engagement of the locking knobs 803 within the limiting notch 802.
[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
