Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and more particularly to a stage light that can automatically maintain lens cleanliness. Background Technology
[0002] In stage lighting equipment, optical lenses are one of the core components for achieving beam adjustment, focusing, and special effects projection. However, existing stage lights often lack effective heat dissipation or airflow cleaning designs, especially in environments where high-power light sources operate for extended periods. The lens surface is prone to accumulating oil mist, dust, or other contaminants due to temperature changes or the evaporation of internal lubricating oil.
[0003] Traditional stage lighting designs often focus on heat dissipation or external protection of the light source, but neglect the need for active cleaning of the lens area. Because the lens surface lacks fan blowing or airflow circulation, oil mist and other deposits gradually accumulate, leading to decreased light transmittance, deteriorated beam quality, and even affecting lighting effects and lifespan. Furthermore, manually cleaning the internal lens requires frequent disassembly and reassembly of the equipment, which is not only cumbersome but can also cause scratches or secondary contamination due to contact with the lens.
[0004] Therefore, there is an urgent need for a solution that can automatically maintain lens cleanliness. Summary of the Invention
[0005] To solve one of the above-mentioned technical problems, this invention provides a stage light that can automatically maintain lens cleanliness.

[0030] As attached Figure 1 To be continued Figure 3 , attached Figure 6As shown, a stage light capable of automatically maintaining the cleanliness of the lens 6 includes a fixing plate 1 for fixed installation inside the stage light. The fixing plate 1 has a horizontal plate portion 11 and a vertical plate portion 12 connected to each other. Specifically, the vertical plate portion 12 is fixedly connected to the inside of the stage light through the fixing plate portion. An air guide cover 2 with an air guide duct 20 is connected between the horizontal plate portion 11 and the vertical plate portion 12. The air guide duct 20 has an air inlet 201 and an air outlet 202 that are connected to each other. The horizontal plate portion 11 has a first channel opening 110 that communicates with the air inlet 201 of the air guide duct 20. The longitudinal plate 12 is provided with a second channel 120 that communicates with the air outlet 202 of the air guide 20. The air guide 20 is provided with a wind-driving component 3 that can drive air from the first channel 110, the air inlet 201, the air outlet 202 and the second channel 120 to the surface of the stage lamp lens 6. The wind-driving component 3 drives the internal airflow of the stage lamp to concentrate and blow it onto the lens 6 in the lamp body, preventing evaporated oil mist and / or dust from adhering to the surface of the lens 6, thereby achieving the effect of cleaning the lens 6, maintaining high-quality light output and reducing the frequency of disassembly and maintenance of the stage lamp.
[0031] As attached Figure 4 As shown, a guide plate 4 is fixedly connected to the longitudinal plate portion 12 of the fixed plate 1 at the second channel opening 120. The guide plate 4 includes two lateral plate portions 41 located on both sides of the second channel opening 120 and an inclined plate portion 42 connecting the two lateral plate portions 41. The two lateral plate portions 41 and the inclined plate portion 42 form an air outlet duct 40 communicating with the second channel opening 120. The guide plate 4 is mainly used to guide the airflow from the second channel opening 120 to be more concentrated and accurately blown onto the surface of the lens 6, thereby improving the cleaning efficiency of the lens 6.
[0032] As attached Figure 4 As shown, the lateral plate 41 has an upper side 411, a lower side 412, and a longest side 413 connected end to end to form an obtuse triangle. The longest side 413 is tightly fitted and fixedly connected to the longitudinal plate 12. The inclined plate 42 is connected between the two lower sides 412, and its lower edge is also tightly fitted to the longitudinal plate 12. This ensures the tightness of the connection between the air guide plate 4 and the fixed plate 1 and prevents excessive gaps from appearing when the air guide plate 4 and the fixed plate 1 are connected, which would affect the air volume. The air outlet 40 has a third channel opening 401 formed by the upper edges of the two upper sides 411 and the inclined plate 42 and facing the surface of the stage light lens 6. Specifically, the third channel opening 401 is located on the lower side of the lens 6.
[0033] As attached Figure 4As shown, each of the two lateral plate portions 41 has an inwardly extending first extension block 414 on its inner side. The first extension block 414 is fixedly connected to the longitudinal plate portion 12 by a first fixing member. The lower edge of the inclined plate portion 42 has a downwardly extending second extension block 415. The second extension block 415 is fixedly connected to the longitudinal plate portion 12 by a second fixing member, thereby completing the fixed connection between the air guide plate 4 and the longitudinal plate portion 12 of the fixing plate 1. Further, one end of the longitudinal plate portion 12 is fixedly connected to the air guide plate 4, while the other end of the longitudinal plate portion 12 is fixedly connected to the air drive component 3. Specifically, the first fixing member passes through the first extension block 414 and the longitudinal plate portion 12 and is fixedly connected to the air drive component 3. Similarly, the second fixing member passes through the second extension block 415 and the longitudinal plate portion 12 and is fixedly connected to the air drive component 3. This installation structure is more compact and simple. The first fixing member and the second fixing member can be screws or bolts.
[0034] As attached Figure 4 As shown, the acute angle formed between the longitudinal plate portion 12 and the inclined plate portion 42 is in the range of 30-60 degrees. Preferably, the included angle formed between the longitudinal plate portion 12 and the inclined plate portion 42 is 45 degrees, so as to maximize the wind-receiving area of the lens 6.
[0035] As attached Figure 2 and attached Figure 5 As shown, the longitudinal plate portion 12 and the transverse plate portion 11 are arranged perpendicularly, forming a right-angled L-shape; the end face of the air guide shroud 2 that is in contact with the transverse plate portion 11 and the end face of the air guide shroud 2 that is in contact with the transverse plate portion 11 are also arranged perpendicularly, so that the air guide shroud 2 forms an L-shape. During installation, the air guide shroud 2 can be more closely installed on the fixed plate 1 to form a sealed air guide channel 20.
[0036] As attached Figure 3 As shown, the end face of the air guide shroud 2 that is in contact with the longitudinal plate 12 is provided with a rectangular air outlet 202, and the air drive component 3 is a rectangular axial flow fan, which is adapted to be installed in the air outlet 202.
[0037] As attached Figure 3 As shown, the air guide hood 2 and the end face of the transverse plate 11 are provided with a U-shaped air inlet 201. The U-shaped air inlet 201 better wraps the first channel opening 110 inside it, ensuring the communication between the air outlet 202 and the first channel opening 110.
[0038] As attached Figure 1 As shown, an air filter 5 for air purification is provided at the air inlet 201. The air filter 5 is an air filter cartridge or an air filter screen, which filters out dirt (such as oil stains, dust, etc.) in the air and blows clean air toward the lens 6 to prevent the lens 6 from being contaminated.
[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
