Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with a ventilated waterproof lamp housing. Background Technology

[0002] In the field of outdoor performance equipment, waterproof stage lights, as the core lighting devices for open-air performances, directly impact the performance effect and equipment safety with their operational reliability. A multi-functional light fixture integrates dynamic pattern panels, color palettes, and cutters, among other effects modules. During operation, these modules generate significant heat loads. Furthermore, since the light source can only convert a portion of electrical energy into light energy, the remaining energy is released as heat. If this heat cannot be dissipated in time, it can lead to malfunctions in the internal components of the lamp head and thermal failure of the drive circuit.

[0003] Current technologies employ a fully sealed lamp head structure for waterproofing, utilizing a fan-driven forced convection circulation to conduct heat to the environment via a heat sink and metal casing. However, with increasing integration of optical systems, traditional solutions are revealing technical limitations: First, the sealed cavity severely restricts ventilation path design, making it difficult to effectively dissipate the combined thermal effects generated when multiple modules work together; second, purely passive casing cooling is inefficient under high-load conditions, easily leading to heat accumulation areas in localized areas of the lamp and accelerating the degradation of electronic components; third, the fully sealed metal casing results in high costs. These problems are particularly prominent in high-power, multi-functional lamps, and existing technologies are insufficient to meet the requirements for long-term stable operation of high-power waterproof stage lights. Therefore, there is an urgent need to overcome the technical limitations of traditional sealed heat dissipation architectures and develop a new lamp body structure that combines good waterproof performance with efficient thermal management, meeting market users' requirements for waterproof performance and heat dissipation in stage lights while effectively reducing costs. Utility Model Content

[0004] To overcome at least one of the defects of the prior art, this utility model provides a stage lamp with a ventilated waterproof lamp housing. By opening the ventilation holes on the housing and using the waterproof and breathable components to prevent moisture from entering the lamp cavity, the lamp body has both good waterproof performance and efficient heat dissipation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage light with a ventilated waterproof lamp housing, including a lamp head with a sealed lamp cavity, a light source installed in the lamp cavity to generate light, and an effect module that interferes with the light to generate light effects. At least a portion of the side wall of the lamp cavity is composed of the outer shell of the lamp head. The outer shell has a vent corresponding to the effect module, and the lamp cavity also has an air outlet that communicates with the outside. It also includes a waterproof and breathable component located in the lamp cavity and covering the vent. The external airflow entering the vent is filtered for moisture by the waterproof and breathable component, exchanges heat with the effect module, and is finally discharged from the lamp cavity through the air outlet.

[0006] The sealed design of the lamp cavity effectively prevents external moisture from entering, providing a stable working environment for the light source and the effect module. However, since the effect module typically contains a large number of driving components and electronic components, and as the power of the light source increases, the effect module generates a continuous heat accumulation effect when producing specific effects with the interference beam. This results in the effect module and its adjacent area having a significantly higher temperature than other parts of the lamp cavity. Therefore, the vent is specifically positioned at the corresponding location of the effect module, allowing external cold air to enter in a shorter distance and directly cool the high-heat area. The airflow after heat exchange is discharged from the lamp cavity through the vent. The waterproof and breathable component ensures smooth airflow while also filtering moisture to prevent its intrusion. The internal waterproof rating of the lamp cavity can reach at least IP54, meeting most outdoor usage scenarios and effectively reducing costs. This allows the lamp cavity to maintain good waterproof performance while significantly improving heat dissipation efficiency through airflow-oriented heat conduction design, ensuring that key components are always within the optimal operating temperature range, achieving a balanced optimization of waterproof and heat dissipation performance.

[0007] Furthermore, the outer shell of the lamp head is composed of multiple shell plates, with at least two ventilation openings on the same shell plate, and a waterproof and breathable component covering all the ventilation openings on the same shell plate. By increasing the number of ventilation openings, the air intake area is increased, further improving heat dissipation efficiency.

[0008] Furthermore, the waterproof and breathable component includes a water-filtering membrane and a mounting frame that fixes it to the inside of the housing. The water-filtering membrane covers the vent, and the mounting frame seals the periphery of the vent. This design prevents moisture from entering the lamp cavity through the gap between the mounting frame and the housing, thus avoiding a failure of the waterproof performance. With this configuration, external airflow must pass through the water-filtering membrane to filter moisture before entering the lamp cavity, ensuring stable and good waterproof performance of the lamp head.

[0009] Furthermore, the mounting frame includes a fixing bracket and a clamping frame for jointly holding the filter membrane. The fixing bracket is located between the filter membrane and the housing and is sealed to the housing. The clamping frame is located on the side of the filter membrane away from the housing. This allows the filter membrane to stably cover the vent, preventing the filter membrane from shifting or even falling off due to excessive airflow, thus avoiding waterproofing failure.

[0010] Furthermore, the clamping frame is provided with a breathable grille corresponding to the filter membrane. The breathable grille supports and holds the filter membrane in place, preventing the filter membrane from bulging when airflow enters from the vent.

[0011] Furthermore, the waterproof and breathable component includes at least two layers of the filter membrane, with a grid mesh disposed between adjacent layers. The grid mesh forms a support structure between the two layers of filter membrane, preventing the filter membrane from collapsing or sticking together due to excessive airflow pressure, thus avoiding blockage of the breathable micropores on the filter membrane and allowing airflow entering from the vent to pass unimpeded through the waterproof and breathable component.

[0012] Furthermore, the waterproof component also includes a support frame located on the housing, the support frame having a plurality of ribs that abut against the water-filtering membrane. The support frame and its ribs prevent the water-filtering membrane from adhering to the inner wall of the housing, thus preventing airflow obstruction; at the same time, a guide channel is formed between adjacent ribs, so that when too much water vapor blocked by the water-filtering membrane accumulates and forms water droplets, as the lamp head rotates, the water droplets will flow out from the vent along the guide channel to the outside of the lamp housing, achieving efficient drainage.

[0013] Furthermore, the filter membrane is made of waterproof polyester fabric. It is lightweight, thin, and easy to install, while also possessing high waterproof performance.

[0014] Furthermore, it also includes a mounting substrate for mounting the light source, the mounting substrate forming part of the sidewall of the lamp cavity, and the air outlet being formed on the substrate.

[0015] Furthermore, it also includes a blower that facilitates the flow of air inside the lamp cavity from the vent to the outlet. This prevents colder airflow from scattering within the lamp cavity after heat exchange with the effect module; instead, the blower directs the airflow in an orderly manner from the outlet, further improving heat dissipation efficiency.

[0016] Furthermore, the pivot side of the lamp head is pivotally connected to the support arm, and the vent is located on the side of the lamp head adjacent to the pivot side. This side has a larger exposed area because it is not blocked by the support arm. This arrangement allows cooler airflow from the outside to enter the lamp cavity at a greater flow rate, significantly improving the heat dissipation efficiency of the effect module.

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0024] like Figures 1 to 2As shown, a stage light with a ventilated waterproof housing includes a lamp head 100 with a sealed lamp cavity 111, a light source that generates light and an effect module 120 that interferes with light to produce a light effect, all installed inside the lamp cavity 111. At least a portion of the side wall of the lamp cavity 111 is composed of the outer shell 160 of the lamp head 100. The outer shell 160 has a vent 140 corresponding to the effect module 120, and the lamp cavity 111 also has an air outlet 150 communicating with the outside. It also includes a waterproof and breathable component 200 located inside the lamp cavity 111 and covering the vent 140. The outside airflow entering the vent 140 is filtered for moisture by the waterproof and breathable component 200, exchanges heat with the effect module 120, and is finally discharged from the lamp cavity 111 through the air outlet 150.

[0025] The sealed design of the lamp cavity 111 effectively prevents external moisture from entering, providing a stable working environment for the light source and the effect module 120. However, since the effect module 120 is typically equipped with a large number of driving components and electronic components, and as the power of the light source increases, the effect module 120 will generate a continuous heat accumulation effect when the interference beam produces specific effects. This results in the temperature of the effect module 120 and its adjacent area being significantly higher than other parts of the lamp cavity 111. Therefore, the vent 140 is specifically set at the corresponding position of the effect module 120, allowing external cold air to enter in a shorter distance and directly cool the high-heat area. The airflow after heat exchange is discharged from the lamp cavity 111 through the air outlet 150. At the same time, the waterproof and breathable component 200, while ensuring smooth airflow, also filters moisture intrusion. This allows the lamp cavity 111 to maintain good waterproof performance while significantly improving heat dissipation efficiency through airflow-oriented heat conduction design, ensuring that key components are always within the optimal operating temperature range, and achieving a balanced optimization of waterproof and heat dissipation performance.

[0026] Preferably, the effect module 120 is at least one of the following: a CMY component, a fixed pattern disk, a rotating pattern disk, a cutter, an aperture component, a color plate disk, or a fire plate.

[0027] Preferably, the vent 140 includes a plurality of through holes arranged along the length of the lamp head 100.

[0028] Preferably, the outer shell 160 is made of metal, which facilitates the dissipation of gas inside the lamp cavity 111 to the outside, further improving heat dissipation efficiency.

[0029] In a preferred embodiment of this invention, the outer shell 160 of the lamp holder 100 is composed of multiple shell plates 161 spliced ​​together. At least two ventilation openings 140 are provided on the same shell plate 161, and a waterproof and breathable component 200 covers all the ventilation openings 140 on the same shell plate 161. By increasing the number of ventilation openings 140, the air intake area is increased, further improving heat dissipation efficiency. The number of ventilation openings 140 can be increased or decreased according to design needs; in this embodiment, it is preferable that each shell plate 161 has two ventilation openings 140.

[0030] Preferably, the outer shell 160 is formed by fastening two shell plates 161 together.

[0031] Preferably, the vent 140 is integrally formed with the shell plate 161.

[0032] like Figures 1 to 3 As shown, in a preferred embodiment of this utility model, the waterproof and breathable component 200 includes a water-filtering membrane 220 and a mounting frame 210 that is fixedly installed inside the outer casing 160. The water-filtering membrane 220 covers the vent 140, and the mounting frame 210 seals the periphery of the vent 140. This design prevents moisture from entering the lamp cavity 111 through the gap between the mounting frame 210 and the outer casing 160, thus avoiding a failure of the waterproof performance. With this configuration, external airflow must pass through the water-filtering membrane 220 to filter moisture before entering the lamp cavity 111, ensuring that the lamp head 100 has stable and good waterproof performance.

[0033] In a preferred embodiment of this invention, the mounting frame 210 includes a fixing bracket 211 and a clamping frame 212 for jointly clamping the filter membrane 220. The fixing bracket 211 is located between the filter membrane 220 and the outer shell 160 and is sealed to the outer shell 160. The clamping frame 212 is located on the side of the filter membrane 220 away from the outer shell 160. This allows the filter membrane 220 to stably cover the vent 140, preventing the filter membrane 220 from shifting or even falling off due to excessive airflow, thus avoiding waterproofing failure.

[0034] Preferably, the filter membrane 220 is first attached to the fixed bracket 211, and then the clamping frame 212 is fixedly connected to the fixed bracket 211, so that the two cooperate to tightly clamp the filter membrane 220.

[0035] Optionally, the mounting frame 210 may have only the fixing bracket 211 or the clamping frame 212.

[0036] In a preferred embodiment of this utility model, the clamping frame 212 is provided with a breathable grille 213 corresponding to the filter membrane 220. The breathable grille 213 supports and holds the filter membrane 220, preventing the filter membrane 220 from bulging when airflow enters from the vent 140.

[0037] In a preferred embodiment of this invention, the waterproof and breathable component 200 includes at least two layers of the filter membrane 220, with a grid mesh 230 disposed between adjacent layers of the filter membrane 220. The grid mesh 230 forms a supporting structure between the two layers of the filter membrane 220, preventing the filter membrane 220 from collapsing or sticking together due to excessive airflow pressure, thus avoiding blockage of the breathable micropores on the filter membrane 220. This allows airflow entering from the vent 140 to pass unimpeded through the waterproof and breathable component 200.

[0038] Preferably, when the mounting frame 210 includes a fixing bracket 211 and a clamping frame 212 for jointly clamping the filter membrane 220, the fixing bracket 211 has a receiving groove 214 for accommodating the grid 230, the filter membrane 220 and at least part of the clamping frame 212.

[0039] In a preferred embodiment of this utility model, the waterproof component further includes a support frame 240 located on the outer shell 160, the support frame 240 having a plurality of ribs 241 abutting against the water filter membrane 220. The support frame 240 and its ribs 241 can prevent the water filter membrane 220 from sticking to the inner wall of the outer shell 160, thus preventing airflow obstruction; at the same time, a guide groove 242 is formed between adjacent ribs 241. When too much water vapor blocked by the water filter membrane 220 accumulates to form water droplets, as the lamp head 100 rotates, the water droplets will flow out from the vent 140 through the guide groove 242 to the outside of the lamp shell, achieving efficient drainage.

[0040] Preferably, the mounting frame 210 and the support frame 240 are sealed together by a waterproof strip, and the mounting frame 210 and / or the support frame 240 have a mounting groove 215 for accommodating at least a portion of the waterproof strip.

[0041] In a preferred embodiment of this invention, the filter membrane 220 is a waterproof polyester fabric. It is lightweight and easy to install, while also possessing high waterproof performance. Preferably, the waterproof polyester fabric is coated with a nano-SiO2-reinforced fluorocarbon coating, which provides high waterproof performance while allowing for a larger flow rate of gas, and offers good cost-effectiveness.

[0042] like Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, a mounting substrate 170 for mounting the light source is also included. The mounting substrate 170 forms part of the sidewall of the lamp cavity 111, and the air outlet 150 is formed on the substrate.

[0043] Preferably, the lamp head 100 has a light outlet 113, which is sealed by the light-emitting lens. The light-emitting lens, the housing 160, and the substrate together form the lamp cavity 111. The side of the housing 160 and the substrate away from the light outlet 113 forms a heat dissipation cavity 112 that communicates with the outside. The hot air inside the lamp cavity 111 is discharged to the outside through the heat dissipation cavity 112 via the air outlet 150.

[0044] Preferably, the light-emitting surface of the light source is located inside the lamp cavity 111, and the other parts of the light source are located inside the heat dissipation cavity 112, which helps to dissipate heat from the light source.

[0045] Preferably, the light source is an LED light source or a laser light source.

[0046] In a preferred embodiment of this invention, a blower 130 is further included to facilitate the flow of air inside the lamp cavity 111 from the vent 140 to the outlet 150. This prevents colder airflow from scattering within the lamp cavity 111 after heat exchange with the effect module 120; instead, the airflow is directed by the blower 130 to flow orderly out of the outlet 150, further improving heat dissipation efficiency. The orderly flow of gas inside the lamp cavity 111 under the influence of the blower 130 also effectively prevents moisture from entering the lamp cavity 111 through the outlet 150.

[0047] Preferably, the air inlet surface of the blower 130 covers the air outlet 150, and the blower 130 strongly exhausts the hot air inside the lamp cavity 111. During the operation of the lamp head 100, it is more difficult for water vapor to enter the lamp cavity 111 from the air outlet 150, thereby further improving the waterproof performance.

[0048] In a preferred embodiment of this invention, the pivot side 180 of the lamp head 100 is pivotally connected to the support arm, and the vent 140 is located on the side of the lamp head 100 adjacent to the pivot side 180. This side, not being obstructed by the support arm, has a larger area exposed to the outside environment. This arrangement allows cooler external airflow to enter the lamp cavity 111 at a greater flow rate, significantly improving the heat dissipation efficiency of the effect module 120.

[0049] Preferably, the support arm is a U-shaped support arm, the pivot side 180 of the lamp head 100 is two opposite sides, and the vent 140 is also located on opposite sides, so that the effect module 120 is cooled simultaneously from two opposite sides, which improves the heat dissipation efficiency of the effect module 120 and also optimizes the internal air duct of the lamp cavity 111.

[0050] Preferably, it also includes a housing for pivoting the support arm, allowing the lamp head 100 to rotate relative to the housing around at least two dimensions to produce more light effect.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
