Description

Technical Field

[0001] The present invention relates to the technical field of stage lights, and particularly to a stage light lamp cover with an automatic dust removal function. Background Art

[0002] Stage and film lights are a type of lighting fixtures used in stage performances and film shootings for illumination and to achieve certain lighting effects. They help to express the content of the program, reflect the author's creative intention, set off the artistic atmosphere, and enable the audience and the camera to obtain the correct color perception and exposure. Different from other lighting fixtures, most of these lighting fixtures have the functions of changing the beam divergence angle, the softness of the light, and the color, and are equipped with special mechanisms such as focusing, iris, and color filter racks.

[0003] A lamp cover is a cover arranged around the lamp flame or on the bulb for concentrating light or protecting against wind and rain. The lamp cover not only serves to gather light together but also prevents electric shock and has a function of protecting the eyes. Common lamp cover materials are generally fabric, PVC, kraft paper, etc. For new LED lamps, the lamp cover is generally made of metal.

[0004] Stage lights are long-term exposed to stage dust, smoke special effects, and airborne suspended particles, resulting in rapid dust accumulation on the surface of the lamp cover, significantly reducing the light transmittance, affecting the beam quality and color rendering. Based on the dust prevention methods of stage light lamp covers in the prior art, the traditional cleaning method is manual wiping, which requires frequent disassembly of the lamp cover, affecting the stability of the performance equipment. Washing or chemical cleaning may damage the coating or circuit components, and real-time dust removal cannot be achieved. Active dust removal (such as electric brushes, air pumps) requires additional energy supply, increasing the volume and power consumption of the lamp, and mechanical components are prone to failure, which is not suitable for high-precision optical equipment. Electrostatic dust removal or filter filtration requires regular replacement of the filter when it is blocked. The electrostatic device may interfere with the electromagnetic performance of the light or generate ozone pollution. Passive coatings (such as hydrophobic materials) only delay the dust accumulation speed and cannot actively remove the attached dust, and still require manual intervention after long-term use.

[0005] In summary, the stage lights in the prior art cannot perform dust removal in real time, resulting in dust accumulation, affecting the stage light, and at the same time causing poor heat dissipation of the stage light. Summary of the Invention

[0006] The present invention provides a stage light lamp cover with an automatic dust removal function, which solves the problems that the stage lights in the prior art cannot perform dust removal in real time, resulting in dust accumulation, affecting the stage light, and at the same time causing poor heat dissipation of the stage light.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A stage light lampshade with an automatic dust removal function, comprising a diversion mechanism arranged outside the stage light. The diversion mechanism includes a mounting frame bolted to the outer wall of one end of the stage light and a spiral diversion plate fixed to the outer wall of the mounting frame. An installation component is arranged outside the mounting frame. The installation component includes an installation ring bolted to the inside of the mounting frame, a plurality of piezoelectric ceramic layers respectively embedded on the outer wall of the installation ring, and a dust-proof ring bolted to the outer wall of the installation ring. A light-shielding component is arranged at one end of the installation ring, and a waterproof component is arranged at one end of the installation ring. The waterproof component includes a waterproof ring sleeved outside the stage light. A cleaning component is arranged inside the mounting frame. The cleaning component includes a mounting ring connected to the inside of the mounting frame through a bearing, a plurality of diversion blades respectively welded to the outer wall of the mounting ring, and a plurality of flexible scraping plates respectively fixed to the outer wall of the mounting ring. A plurality of return pipes are arranged outside the installation ring.

[0009] Preferably, a plurality of air inlets are opened on the inner wall of the mounting frame close to one end of the stage light, and a plurality of air outlets are opened on one outer wall of the mounting frame.

[0010] Preferably, the installation ring is composed of two semi-circular installation blocks, the dust-proof ring is composed of two semi-circular dust-proof rings, a plurality of fixing grooves are opened on the inner wall of the dust-proof ring, and the upper part of the piezoelectric ceramic layer is sleeved in the fixing grooves.

[0011] Through the above scheme, the current pulse signal generated when the stage light is powered on enables the piezoelectric ceramic layer to be powered on to generate high-frequency micro-vibrations, so that the dust on the dust-proof ring falls off the dust-proof ring under the action of the high-frequency micro-vibrations.

[0012] Preferably, the light-shielding component includes a fixing ring bolted to the outer wall of the mounting frame and four light-shielding plates respectively connected to the outer wall of the fixing ring through hinges.

[0013] Preferably, the waterproof ring is welded to the outer wall of one of the installation blocks. A ventilation plate is bolted to one outer wall of the waterproof ring, and a plurality of air outlets are opened on the outer wall of the ventilation plate. Two fixing columns are welded to the outer walls on both sides of the waterproof ring.

[0014] Preferably, a plurality of the diversion blades respectively abut against the inner wall of the fixing ring, and a plurality of the flexible scraping plates respectively 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 one end of the return pipe is fixed to the inner wall of the fixing ring.

[0016] Preferably, a nano-hydrophobic coating is sprayed on the inner wall of the mounting frame, and anti-static coatings are electroplated on the outer walls of the installation ring and the waterproof ring.

[0017] Through the above solution, the heat generated when the stage light is 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 is discharged from the exhaust port on one side of the mounting frame. The hot air impacts a plurality of guide vanes, and the guide vanes drive the mounting ring to rotate. The mounting ring drives a plurality of flexible scraping plates 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 air flow, the dust enters the mounting frame and is discharged outside the mounting frame.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The current pulse signal generated when the stage light is powered on causes the piezoelectric ceramic layer to be powered on to generate high-frequency micro-vibrations, causing the dust on the dust-proof ring to break away from the dust-proof ring under the action of the high-frequency micro-vibrations, and it can generate high-frequency vibrations during the operation of the stage light to make the dust break away.

[0020] 2. The heat generated when the stage light is 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 is discharged from the exhaust port on one side of the mounting frame. The hot air impacts a plurality of guide vanes, and the guide vanes drive the mounting ring to rotate. The mounting ring drives a plurality of flexible scraping plates 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 air flow, the dust enters the mounting frame and is discharged outside the mounting frame, and it can use the heat generated during the operation of the stage light to scrape the dust in the lampshade in real time.

[0021] In summary, the present invention can generate high-frequency vibrations during the operation of the stage light to make the dust break away, can use the heat generated during the operation of the stage light to scrape the dust in the lampshade in real time, perform comprehensive dust removal treatment on the lampshade, and prevent the light and heat dissipation performance of the stage light from being affected.
