Abstract
Description
Technical Field
[0001] This invention relates to the field of stage lighting technology, and in particular to a stage light cover with an automatic dust removal function. Background Technology
[0002] Stage and film lighting is a type of lighting fixture used in stage performances and film and television shooting for illumination and to achieve certain lighting effects. It helps to express the content of the program, reflect the author's creative intentions, create an artistic atmosphere, and enable the audience and camera to obtain the correct color perception and exposure. Unlike other lighting fixtures, most of these fixtures have the function of changing the beam diffusion angle, the softness of the light, and the color, and are equipped with special mechanisms such as focusing, aperture, and color filter.
[0003] A lampshade is a cover placed around the flame of a lamp or on a light bulb to focus light or protect it from wind and rain. A lampshade not only serves to concentrate light, but also helps prevent electric shock and protects the eyes. Common lampshade materials include fabric, PVC, and kraft paper. For newer LED lamps, the lampshade is usually made of metal.
[0004] Stage lights are constantly exposed to stage dust, smoke effects, and airborne particulate matter, causing rapid dust accumulation on the lampshade surface, significantly reducing light transmittance and affecting beam quality and color reproduction. Current dust prevention methods for stage lights involve manual wiping, requiring frequent disassembly and impacting equipment stability. Water washing or chemical cleaning can damage coatings or circuit components and cannot achieve real-time dust removal. Active dust removal (such as electric brushes and air pumps) requires additional energy, increasing lamp size and power consumption, and mechanical components are prone to failure, making them unsuitable for high-precision optical equipment. Electrostatic dust removal or filter filtration requires periodic filter replacement when clogged, and electrostatic devices may interfere with the electromagnetic performance of the lights or generate ozone pollution. Passive coatings (such as hydrophobic materials) only slow down dust accumulation but cannot actively remove existing dust, still requiring manual intervention after long-term use.
[0005] In summary, existing stage lights cannot be dusted in real time, resulting in dust accumulation, which affects the stage light's illumination and also worsens the stage light's heat dissipation. Summary of the Invention
[0006] This invention provides a stage light cover with an automatic dust removal function, which solves the problem in the prior art that stage lights cannot be dusted in real time, resulting in dust accumulation, which affects the stage light and causes poor heat dissipation.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A stage light lampshade with automatic dust removal function includes a flow guiding mechanism disposed outside the stage light. The flow guiding mechanism includes a mounting frame bolted to the outer wall of one end of the stage light and a spiral flow guiding plate fixed to the outer wall of the mounting frame. An installation assembly is provided outside the mounting frame. The installation assembly includes a mounting ring bolted to the mounting frame, several piezoelectric ceramic layers respectively embedded in the outer wall of the mounting ring, and a dustproof ring bolted to the outer wall of the mounting ring. A light-shielding assembly is provided at one end of the mounting ring, and a waterproof assembly is provided at the other end of the mounting ring. The waterproof assembly includes a waterproof ring sleeved on the outside of the stage light. A cleaning assembly is provided inside the mounting frame. The cleaning assembly includes a mounting ring connected to the mounting frame via a bearing, several flow guiding blades respectively welded to the outer wall of the mounting ring, and several flexible scrapers respectively fixed to the outer wall of the mounting ring. Several return pipes are provided outside the mounting ring.
[0009] Preferably, the mounting frame has several air inlets on the inner wall of the end near the stage light, and several exhaust outlets on the outer wall of one side of the mounting frame.
[0010] Preferably, the mounting ring is composed of two semi-circular mounting blocks, the dustproof ring is composed of two semi-circular dustproof rings, the inner wall of the dustproof ring has several fixing grooves, and the upper part of the piezoelectric ceramic layer is fitted into the fixing grooves.
[0011] The above scheme uses the current pulse signal generated when the stage lights are powered on to cause the piezoelectric ceramic layer to be energized and generate high-frequency micro-vibration, which causes the dust on the dustproof ring to be removed from the dustproof ring under the action of high-frequency micro-vibration.
[0012] Preferably, the light-shielding assembly includes a fixing ring bolted to the outer wall of the mounting frame and four light-shielding plates hinged to the outer wall of the fixing ring.
[0013] Preferably, the waterproof ring is welded to one of the outer walls of one of the mounting blocks, and a ventilation plate is bolted to one of the outer walls of the waterproof ring. Several air outlets are opened on the outer wall of the ventilation plate, and two fixing posts are welded to the outer walls of both sides of the waterproof ring.
[0014] Preferably, several of the guide vanes abut against the inner wall of the fixed ring, and several flexible scrapers abut against the inner wall of the mounting frame.
[0015] Preferably, one end of the return pipe is fixed to the inner wall of the waterproof ring, and the other end of the return pipe is fixed to the inner wall of the fixed ring.
[0016] Preferably, the inner wall of the mounting frame is coated with a nano-hydrophobic coating, and the outer walls of the mounting ring and the waterproof ring are electroplated with an antistatic coating.
[0017] With the above solution, the heat generated when the stage lights are powered on enters the space between the mounting frame and the mounting ring through the air inlet. The hot air flows along the spiral guide plate and then exits from the exhaust port on one side of the mounting frame. The hot air impacts multiple guide vanes, which drive the mounting ring to rotate. The mounting ring drives multiple flexible scrapers to rotate along the inner wall of the mounting frame, thereby cleaning the dust on the inner wall of the mounting frame. Then, under the action of airflow, the dust enters the mounting frame and is discharged to the outside of the mounting frame.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. The current pulse signal generated when the stage light is powered on causes the piezoelectric ceramic layer to generate high-frequency micro-vibration, which causes the dust on the dustproof ring to detach under the action of high-frequency micro-vibration. The high-frequency vibration generated when the stage light is running can cause the dust to detach.
[0020] 2. When the stage light is powered on, the heat generated enters the space between the mounting frame and the mounting ring through the air inlet. The hot air flows along the spiral guide plate and is then discharged from the exhaust port on one side of the mounting frame. The hot air impacts multiple guide vanes, which drive the mounting ring to rotate. The mounting ring drives multiple flexible scrapers to rotate along the inner wall of the mounting frame, thereby cleaning the dust on the inner wall of the mounting frame. Subsequently, under the action of airflow, the dust enters the mounting frame and is discharged to the outside of the mounting frame. The heat generated when the stage light is running can be used to scrape the dust inside the lampshade in real time.
[0021] In summary, this invention can generate high-frequency vibrations during stage light operation to remove dust, and can utilize the heat generated during stage light operation to scrape away dust inside the lampshade in real time, performing comprehensive dust removal on the lampshade and preventing the stage light's lighting and heat dissipation performance from being affected.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0031] Example 1, referring to Figure 1-6A stage light lampshade with automatic dust removal function includes a flow guiding mechanism 2 disposed outside the stage light 1. The flow guiding mechanism 2 includes a mounting frame 201 bolted to the outer wall of one end of the stage light 1 and a spiral flow guiding plate 202 fixed to the outer wall of the mounting frame 201. The inner wall of the mounting frame 201 near the stage light 1 has several air inlets 21, and the outer wall of the mounting frame 201 has several exhaust outlets 22, allowing the heat generated during the operation of the stage light 1 to pass through the air inlets 21 and exhaust outlets 22. An installation assembly 3 is disposed outside the mounting frame 201. The installation assembly 3 includes a mounting ring 301 bolted to the mounting frame 201, several piezoelectric ceramic layers 302 respectively embedded in the outer wall of the mounting ring 301, and a dustproof ring 303 bolted to the outer wall of the mounting ring 301. The mounting ring 301 consists of two semi-circular mounting blocks, providing dust protection. The ring 303 consists of two semi-circular dustproof rings. Several fixing grooves are opened on the inner wall of the dustproof ring 303. The upper part of the piezoelectric ceramic layer 302 is fitted into the fixing groove. The light-shielding component 4 includes a fixing ring 401 connected to the outer wall of the mounting frame 201 by bolts and four light-shielding plates 402 respectively connected to the outer wall of the fixing ring 401 by hinges. One end of the mounting ring 301 is provided with a waterproof component 5. The waterproof component 5 includes a waterproof ring 501 fitted on the outside of the stage light 1. The waterproof ring 501 is welded to one side of the outer wall of one of the mounting blocks. A ventilation plate 502 is connected to one side of the outer wall of the waterproof ring 501 by bolts. Several air outlets are opened on the outer wall of the ventilation plate 502. Two fixing posts 503 are welded on the outer walls of both sides of the waterproof ring 501. The inner wall of the mounting frame 201 is sprayed with a nano hydrophobic coating. The outer walls of the mounting ring 303 and the waterproof ring 501 are electroplated with an antistatic coating.
[0032] Example 2, refer to Figure 7 A stage light lampshade with automatic dust removal function also includes a light-shielding component 4 and a cleaning component 6. The cleaning component 6 includes a mounting ring 601 connected to the mounting frame 201 via a bearing, several guide vanes 602 respectively welded to the outer wall of the mounting ring 601, and several flexible scrapers 603 respectively fixed to the outer wall of the mounting ring 601. The guide vanes 602 respectively abut against the inner wall of the fixing ring 401, and the flexible scrapers 603 respectively abut against the inner wall of the mounting frame 201.

One end of the return pipe 7 is fixed to the inner wall of the waterproof ring 501, and the other end of the return pipe 7 is fixed to the inner wall of the fixing ring 401.
[0033] When the stage light 1 is powered on, the current pulse signal causes the piezoelectric ceramic layer 302 to vibrate at a high frequency. This causes the dust on the dustproof ring 303 to detach from the dustproof ring 303 under the action of the high-frequency micro-vibration. At the same time, the heat generated when the stage light 1 is powered on enters the space between the mounting frame 201 and the mounting ring 301 through the air inlet 21. The hot air flows along the spiral guide plate 202 and is then discharged from the exhaust port 22 on one side of the mounting frame 201. The hot air impacts multiple guide vanes 602, which drive the mounting ring 601 to rotate. The mounting ring 601 drives multiple flexible scrapers 603 to rotate along the inner wall of the mounting frame 201, thereby cleaning the dust on the inner wall of the mounting frame 201. Then, under the action of air flow, the dust enters the mounting frame 201 and is discharged to the outside of the mounting frame 201.
