Description

Technical Field

[0001] The invention relates to the technical field of lighting devices, and in particular to an energy-saving stage lighting device capable of preventing lens fogging. Background Art

[0002] Stage lighting fixtures are lighting equipment used in stage performances and activities. They enhance visual effects, create atmosphere, highlight actors and props, and guide the audience's sight by projecting light of different colors, brightness, patterns and dynamic effects.

[0003] Because stage lamps will generate a lot of heat after working for a long time, the internal temperature of the lamps will rise, while the external ambient temperature is low. When the lens is in a high temperature state, its surface temperature is high. When the lens is exposed to low-temperature air, the water vapor in the air will be cooled and liquefied on the lens surface to form small water droplets, which will cause the outside of the stage lamp lens to fog.

[0004] In the prior art, a multi-layer lens combination is used to achieve fine-tuning of the beam angle by changing the arrangement or position of the lens group. The multi-layer lens combination and the corresponding control system are complex in design, which increases the manufacturing cost and maintenance cost of the lamp. The movement of the lens group will affect the overall stability of the lamp, especially in the case of frequent adjustments or vibrations. The lenses and optical elements will heat up due to long-term use. The multi-layer lens combination is more likely to cause fogging of the stage lamp lens. The multi-layer lens combination requires more frequent cleaning and maintenance to ensure optimal optical performance.

[0005] Since stage lamps are usually equipped with ventilation devices, when the ventilation devices are turned on, tiny particles such as dust and fibers in the air will flow into the interior of the lamp with the air and adhere to the surface of the lens. The dust, stains, etc. on the lens will block the light and affect the lighting effect of the lamp, resulting in a decrease in the brightness and clarity of the stage lights. The contaminated lens will reduce the light transmittance of the lamp, so that the lamp requires greater power to achieve the same lighting effect, thereby increasing energy consumption. In the prior art, it is necessary to disassemble the outer casing of the stage lamp and maintain and clean the lens inside it with a manual handheld wiping tool. Disassembling the lamp casing involves sharp edges of the casing, increasing the risk of injury to the operator. Disassembling and assembling the lamp casing requires extra time, which increases the overall time cost of maintenance and cleaning. During the disassembly process, if you are not careful, the structure or internal components of the lamp may be damaged, causing the lamp to fail to work properly.

[0006] Therefore, an energy-saving stage lighting device which can avoid lens fogging is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose an energy-saving stage lighting device that can avoid lens fogging, so as to solve the problems that the prior art multi-layer lens combination and the corresponding control system are complex in design, which increases the manufacturing cost and maintenance cost of the lamp, and the multi-layer lens combination will introduce spherical aberration, resulting in a decrease in the imaging quality at the edge of the light beam, and the disassembly of the lamp housing will involve the sharp edges of the housing, increasing the risk of injury to the operator, and the disassembly and assembly of the lamp housing requires additional time, which will increase the overall time cost of maintenance and cleaning.

[0012] Preferably, a second disk is fixedly connected to a side of the shell close to the lighting device body, a ring is fixedly connected to a side of the second disk away from the lighting device body, a reset spring is fixedly connected between the second disk and the first gear ring, a connecting column is slidably connected to a side of the first gear ring away from the second gear ring, and the connecting column is rotatably connected to the inside of the shell, the second disk and the ring.

[0013] Preferably, the auxiliary protection mechanism also includes a circular outer frame, the first auxiliary plate is fixedly connected to the end of the connecting column away from the outer shell, the end of the connecting column away from the first auxiliary plate is fixedly connected to the side of the first disk close to the outer shell, the circular outer frame is rotatably connected to one side of the first auxiliary plate, two connecting plates are fixedly connected to the arc surface of the first auxiliary plate, the upper and lower ends of the two connecting plates are slidably connected to baffles, and the bottom surface of the baffle slidably connected above the connecting plate is fixedly connected to a contact.

[0014] Preferably, the inner wall side of the circular outer frame is rotatably connected to a direction converter, the end of the direction converter away from the circular outer frame is fixedly connected to a reciprocating screw, the outer surface of the reciprocating screw is threadedly connected to a scraper, and the scraper is slidably connected to the surface of the lens body.

[0015] Preferably, the inner wall side surface of the circular outer frame is rotatably connected to a first cylinder, the first cylinder is rotatably connected to a rectangular trough body at an eccentric point away from the circular outer frame, the side surface of the rectangular trough body is fixedly connected to a push rod, the inner wall side surface of the circular outer frame is fixedly connected to an auxiliary cylinder, and the side of the auxiliary cylinder away from the push rod is fixedly connected to a hose.

[0016] Preferably, the contact is electrically connected to the drive device.

[0017] Preferably, the push rod is slidably connected to the auxiliary cylinder.

[0018] Compared with the prior art, the present invention provides an energy-saving stage lighting device that can avoid lens fogging, and has the following beneficial effects:

[0019] 1. The deflection angle of the lens can be manually adjusted through the cooperation between the first disc, button, first gear ring, second gear ring, third disc and connecting column in the auxiliary adjustment mechanism. Adjusting the lens angle can change the contact area between the lens and the surrounding environment, thereby changing the efficiency of heat conduction, thereby reducing the possibility of lens fogging. When the surface temperature of the lens is high, its radiation heat dissipation capacity is weak. By adjusting the lens angle, the surface area of ​​the lens surface can be increased, so that its radiation heat dissipation capacity is enhanced, thereby reducing the temperature of the lens surface. Manual adjustment of the lens deflection angle usually does not require a complex control system. The operation is simple and intuitive, easy to learn and use. Manual adjustment can provide instant feedback and adjustment, which is suitable for fast-changing stage performances and can quickly respond to the needs of directors or performers. , Manual adjustment systems are usually lower in cost and do not require complex lens combinations and control systems. Manual adjustment can provide more refined control. Operators can make fine adjustments according to specific scenes and needs to achieve unique visual effects. Manually adjusted lens systems are usually simpler than multi-layer lens combinations, so they may reduce optical effects such as spherical aberration and chromatic aberration, maintain image quality, and manual adjustments are more stable because they do not have moving parts that appear in multi-layer lens combinations, reducing the instability caused by mechanical movement. Since manual adjustment systems are usually lighter, they are more suitable for stage lamps that need to be moved frequently, easy to carry and install, and manual adjustment provides more artistic freedom. Operators can adjust the beam according to their intuition and creativity to create unique stage effects.

[0020] 2. Through the cooperation between the circular outer frame, the connecting plate and the baffle in the auxiliary protection mechanism, the lens inside the stage lighting device can be protected when it is not in use. Since dust and dirt easily accumulate on the surface of the lens, this will reduce the lighting effect and may affect the quality of light. Protecting the lens can prevent the intrusion of dust and dirt. Lens protection can prevent moisture and corrosive gases from entering the interior of the lamp, avoiding damage to the lens due to moisture or chemical corrosion. Lens protection can prevent internal short circuits or other electrical problems caused by lens damage, thereby improving safety during use. When the stage lighting device needs to be moved or stored, protecting the lens can prevent damage caused by collision or vibration during transportation and storage.

[0021] 3. Through the cooperation among the scraper, the first cylinder, the rectangular trough, the push rod, the auxiliary cylinder and the hose in the auxiliary protection mechanism, the lens can be maintained without disassembling the lamp. The structural integrity of the lamp can be maintained without disassembling it, avoiding structural damage or loosening of internal components caused by improper disassembly. Disassembling the lamp will cause unnecessary vibration and wear to the internal components of the lamp, but these problems can be avoided without disassembling it. By applying an anti-reflective coating, stains and reflections on the lens can be reduced, thereby reducing the maintenance frequency of the lens. The anti-reflective coating can significantly reduce the reflection loss of light on the lens surface, allowing more light to pass through the lens, thereby improving the efficiency of the entire lighting system.

[0036] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0037] Example

[0038] Please refer to Figures 1 to 4 As shown:

[0039] In order to solve the problem mentioned in the technical solution, the embodiment of the present application provides an energy-saving stage lighting device that can prevent lens fogging, including: a lighting device body 1, a sliding frame 2 is slidably connected to the arc surface of the lighting device body 1, an electric telescopic rod 4 is fixedly connected to the side face of the sliding frame 2, and the end of the electric telescopic rod 4 away from the sliding frame 2 is fixedly connected to the arc surface of one end of the lighting device body 1, an auxiliary adjustment mechanism for preventing lens fogging is arranged inside the sliding frame 2, and an auxiliary protection mechanism for protecting the lighting device is arranged inside the lighting device body 1;

[0040] The auxiliary adjustment mechanism comprises a housing 301, and a first disc 302 for driving the auxiliary adjustment mechanism to rotate is rotatably connected to a side of the housing 301 away from the lighting device body 1;

[0041] The auxiliary adjustment mechanism also includes a button 303. The shell 301 is fixedly connected to the arc surface of the lighting device body 1. The button 303 is fixedly connected to the side of the first disk 302 away from the shell 301. The side of the shell 301 away from the button 303 is fixedly connected to the third disk 309. The side of the third disk 309 away from the first disk 302 is fixedly connected to the second toothed ring 308. The side of the second toothed ring 308 away from the third disk 309 is clamped with the first toothed ring 307.

[0044] In the prior art, a multi-layer lens combination is used to achieve fine-tuning of the light beam angle by changing the arrangement or position of the lens group. The multi-layer lens combination and the corresponding control system are complex in design, which increases the manufacturing cost and maintenance cost of the lamp. The multi-layer lens combination will introduce spherical aberration, resulting in a decrease in the imaging quality of the edge of the light beam. Light of different wavelengths has different refractive indices when passing through different materials. The multi-layer lens combination will aggravate chromatic aberration and affect color purity. The lens combination will produce aberrations such as astigmatism and distortion, which affect the clarity and accuracy of the image. The adjustment of the multi-layer lens combination is more complicated than that of a single lens, requiring more delicate operations and more adjustment time. Compared with the prior art, the deflection angle of the lens can be manually adjusted through the cooperation between the first disk 302, the button 303, the first gear ring 307, the second gear ring 308, the third disk 309 and the connecting column 310 in the auxiliary adjustment mechanism. Manual adjustment of the lens deflection angle usually does not require a complex control system. The operation is simple and intuitive, easy to learn and use, manual adjustment can provide instant feedback and adjustment, suitable for rapidly changing stage performances, and can quickly respond to the needs of directors or performers. Manual adjustment systems are usually low-cost and do not require complex lens combinations and control systems. Manual adjustment can provide more refined control, and operators can fine-tune according to specific scenes and needs to achieve unique visual effects. Manually adjusted lens systems are usually simpler than multi-layer lens combinations, so they may reduce optical effects such as spherical aberration and chromatic aberration, maintain image quality, and manual adjustments are more stable because they do not have moving parts that appear in multi-layer lens combinations, reducing the instability caused by mechanical movement. Since manual adjustment systems are usually lighter, they are more suitable for stage lamps that need to be moved frequently, easy to carry and install, and manual adjustment provides more artistic freedom. Operators can adjust the light beam according to their intuition and creativity to create unique stage effects.

[0045] For further examples, please refer to Figures 5 to 8 As shown:

[0046] The auxiliary protection mechanism comprises a first auxiliary plate 501, and a lens body 502 for adjusting lighting is fixedly connected inside the first auxiliary plate 501;

[0047] The auxiliary protection mechanism also includes a circular outer frame 503, a first auxiliary plate 501 is fixedly connected to one end of the connecting column 310 away from the outer shell 301, and one end of the connecting column 310 away from the first auxiliary plate 501 is fixedly connected to a side of the first disk 302 close to the outer shell 301. The circular outer frame 503 is rotatably connected to one side of the first auxiliary plate 501, and two connecting plates 504 are fixedly connected to the arc surface of the first auxiliary plate 501. The upper and lower ends of the two connecting plates 504 are slidably connected to baffles 505, and the bottom surface of the baffle 505 slidably connected above the connecting plate 504 is fixedly connected to a contact 506.

[0048] The inner wall side of the circular outer frame 503 is rotatably connected to a direction converter 507, and the end of the direction converter 507 away from the circular outer frame 503 is fixedly connected to a reciprocating screw 508, and the outer surface of the reciprocating screw 508 is threadedly connected to a scraper 509, and the scraper 509 is slidably connected to the surface of the lens body 502.

[0049] The inner wall side surface of the circular outer frame 503 is rotatably connected to the first cylinder 510, and the first cylinder 510 is rotatably connected to the rectangular groove body 511 at an eccentric point away from the circular outer frame 503, and the side of the rectangular groove body 511 is fixedly connected to the push rod 512, and the inner wall side surface of the circular outer frame 503 is fixedly connected to the auxiliary cylinder 513, and the side of the auxiliary cylinder 513 away from the push rod 512 is fixedly connected to the hose 514.

[0050] Among them: there is a certain gap between the first auxiliary plate 501, the circular outer frame 503 and the inner wall of the lighting device body 1, the circular outer frame 503 is provided with an arc groove, and is slidably adapted to the baffle 505, mainly used to control the baffle 505 to slide up and down, the contact 506 is electrically connected to the driving device, the driving device can drive the direction converter 507 to rotate, and a belt is connected between the direction converter 507 and the first cylinder 510, the scraper 509 is hollow and contains anti-reflective liquid, the side of the scraper 509 close to the lens body 502 is made of soft sponge material, which will not cause damage to the lens body 502, the auxiliary cylinder 513 can be externally connected to an automatic anti-reflective liquid device, and the hose 514 can be freely retracted.

[0051] In the prior art, it is necessary to disassemble the stage lamp and maintain and clean the lens inside it by manually holding a wiping tool. Disassembling the lamp involves sharp edges, which increases the risk of injury to the operator. Disassembling and assembling the lamp requires extra time, which increases the overall time cost of maintenance and cleaning. During the disassembly process, if you are not careful, the structure or internal components of the lamp may be damaged, causing the lamp to fail to work properly. Compared with the prior art, through the cooperation between the scraper 509, the first cylinder 510, the rectangular trough 511, the push rod 512, the auxiliary cylinder 513 and the hose 514 in the auxiliary protection mechanism, the lens can be maintained without disassembling the lamp. Not disassembling the lamp can maintain its structural integrity and avoid structural damage or loosening of internal components caused by improper disassembly. Disassembling the lamp will cause unnecessary vibration and wear to the internal components of the lamp, but not disassembling it can avoid these problems. By applying an anti-reflective coating, stains and reflections on the lens can be reduced, thereby reducing the maintenance frequency of the lens. The anti-reflective coating can significantly reduce the reflection loss of light on the lens surface, allowing more light to pass through the lens, thereby improving the efficiency of the entire lighting system.

[0052] Everything in the above example works like this:

[0053] In the initial state: the scraper 509 is filled with anti-reflection liquid, and the scraper 509 is located at the end of the reciprocating screw 508 away from the direction converter 507 , and will not affect the refracted light beam of the lens body 502 .

[0054] The following is the working process of the auxiliary adjustment mechanism adjusting the deflection angle of the lens body 502:

[0055] When in use, the button 303 is manually grasped and then pushed in the direction close to the lighting device body 1. The button 303 moves in the direction close to the lighting device body 1, driving the first disk 302 fixedly connected thereto to move together. The movement of the first disk 302 drives the connecting column 310 fixedly connected thereto to move. The movement of the connecting column 310 drives the first gear ring 307 fixedly connected thereto to move together, so that the first gear ring 307 is no longer engaged with the second gear ring 308. The movement of the first gear ring 307 squeezes and compresses the reset spring 306, and then the button 303 is rotated. Since the button 303 is fixedly connected to the first disk 302, that is, the first disk 302 rotates, the rotation of the first disk 302 drives the connecting column 310 to rotate, and the connecting column 310 The rotation drives the first gear ring 307 to rotate, and the rotation of the connecting column 310 drives the first auxiliary plate 501 and the lens body 502 fixedly connected thereto to rotate together, so that the deflection angle of the lens can be manually adjusted. By adjusting the lens angle, the contact area between the lens and the surrounding environment can be changed, thereby changing the efficiency of heat conduction. Because when the lens angle is small, the light will pass through the lens more concentratedly to form a narrower light beam. At this time, the contact area between the lens and the surrounding environment is relatively small. On the contrary, when the lens angle is large, the light will pass through the lens more dispersedly to form a wider light beam. At this time, the contact area between the lens and the surrounding environment is relatively large, thereby reducing the possibility of lens fogging. When the surface temperature of the lens is high, its radiation heat dissipation ability is weak. By adjusting the lens angle, In order to increase the surface area of ​​the lens surface and enhance its radiation heat dissipation capacity, it is because the angle adjustment of the lens will change the divergence angle of the light. The appropriate angle can scatter the light in a larger range, reduce the phenomenon of light concentration at a certain point, and reduce the local temperature of the light source. The change of the lens angle can make the light irradiate to a wider area, thereby increasing the effective contact area of ​​the lens surface. If the light can be more evenly distributed on the lens surface, the heat can be taken away more effectively, reducing the heat accumulation. With the increase of the irradiation area, the flow of surrounding air and the effect of thermal convection will also improve, because the increased irradiation area will provide more paths and space for air flow. The air will rise after being heated, and cold air will flow in from the surroundings. A more efficient convection cycle is formed, which can take away heat more quickly, thereby improving the heat dissipation effect and reducing the temperature of the lens surface. Manual adjustment of the lens deflection angle usually does not require a complex control system. The operation is simple and intuitive, easy to learn and use. Manual adjustment can provide instant feedback and adjustment, which is suitable for fast-changing stage performances and can quickly respond to the needs of directors or performers. Manual adjustment systems are usually low-cost and do not require complex lens combinations and control systems. Manual adjustment can provide more precise control. Operators can make fine adjustments according to specific scenes and needs to achieve unique visual effects. Manually adjusted lens systems are usually simpler than multi-layer lens combinations, so they may reduce optical effects such as spherical aberration and chromatic aberration, maintain image quality,Manual adjustments are more stable because they do not have the moving parts that appear in multi-layer lens combinations, reducing the instability caused by mechanical movement. Since manual adjustment systems are usually lighter, they are more suitable for stage lamps that need to be moved frequently, easy to carry and install, and manual adjustment provides more artistic freedom. Operators can adjust the beam according to their intuition and creativity to create unique stage effects.

[0056] Please refer to the above working process Figures 1 to 4 .

[0057] The following is the working process of the auxiliary protection mechanism protecting the lens body 502:

[0058] When in use, when the stage lighting device stops being used, the motor drives the circular outer frame 503 to rotate. Since the circular outer frame 503 is provided with an arc groove and is slidably adapted to the baffle 505, it is mainly used to control the baffle 505 to slide up and down, that is, when the circular outer frame 503 rotates, the two baffles 505 move toward each other, thereby protecting the lens body 502 inside the circular outer frame 503 and protecting the lens inside. Since dust and dirt are easily accumulated on the surface of the lens, which will reduce the lighting effect and may affect the quality of light, protecting the lens can prevent the intrusion of dust and dirt. Lens protection can prevent moisture and corrosive gases from entering the interior of the lamp, avoiding damage to the lens due to moisture or chemical corrosion. Lens protection can prevent internal short circuits or other electrical problems caused by lens damage, thereby improving safety during use. When the stage lighting device needs to be moved or stored, protecting the lens can prevent damage caused by collision or vibration during transportation and storage;

[0059] When the two baffles 505 move toward each other, the upper baffle 505 is fixedly connected to a contact 506 on the opposite side, that is, when the two baffles 505 are pressed together, they will touch the contact 506. Since the contact 506 is electrically connected to the driving device, the driving device can drive the direction converter 507 to rotate, that is, the rotation of the direction converter 507 drives the reciprocating screw 508 fixedly connected to it to rotate, thereby controlling the scraper 509 to reciprocate on the surface of the lens body 502. At the same time, since a belt is connected between the direction converter 507 and the first cylinder 510, that is, the rotation of the direction converter 507 drives the first cylinder 510 to rotate together, and the rotation of the first cylinder 510 drives the rectangular groove body 511 connected to the eccentric part to slide, and the sliding of the rectangular groove body 511 drives the push rod 512 fixedly connected to it to slide inside the auxiliary cylinder 513. Since the auxiliary cylinder 513 can be externally connected with an automatic anti-reflection liquid device, that is, when the push rod 5 When 12 moves back and forth, the anti-reflective liquid in the auxiliary cylinder 513 is injected into the interior of the scraper 509 through the hose 514, and the hose 514 can be freely retracted. The side of the scraper 509 close to the lens body 502 is made of soft sponge material, which will not cause damage to the lens body 502. Then, the anti-reflective liquid is coated on the surface of the lens body 502 for maintenance through the reciprocating movement of the scraper 509. The lens can be maintained without disassembling the lamp. The structural integrity of the lamp can be maintained without disassembling it, avoiding structural damage or loosening of internal components caused by improper disassembly. Disassembling the lamp will cause unnecessary vibration and wear to the internal components of the lamp, but these problems can be avoided without disassembling it. By applying the anti-reflective coating, the stains and reflections on the lens can be reduced, thereby reducing the maintenance frequency of the lens. The anti-reflective coating can significantly reduce the reflection loss of light on the lens surface, allowing more light to pass through the lens, thereby improving the efficiency of the entire lighting system.
