LED lighting devices have a long lifespan, and LEDs can achieve various color and brightness adjustments to meet the needs of different scenarios. In terms of environmental protection, they do not contain harmful substances and have low power consumption, reducing energy consumption and carbon emissions. Whether in households, commercial venues, or industrial fields, LED lighting devices can provide a reliable, efficient, and comfortable lighting experience and are an ideal choice for modern lighting.

[0003] An LED lighting device with linear dimming drive is an advanced lighting equipment. It adopts linear dimming technology to achieve smooth adjustment of the light brightness and meet the lighting needs of different scenarios. This device has the characteristics of high energy efficiency, significantly reducing energy consumption compared to traditional lighting equipment. Its light emission is stable without flicker, effectively protecting eyesight. The LED chips have a long lifespan, reducing the frequency and cost of replacing the lighting fixtures. Linear dimming drive can also create a comfortable light environment and is applicable to households, office places, or commercial spaces, bringing a high-quality lighting experience to people.

[0004] In the prior art, for an invention such as the one with the publication number CN115711373A, the present invention relates to the technical field of LED lighting, and particularly to an LED lighting device, including an LED projection lamp. The LED projection lamp consists of an LED light source, a housing for installing a circuit board, and a power supply box. It also includes a protection mechanism provided on the heat dissipation groove for protecting the circuit board in rainy weather. The protection mechanism includes installation grooves opened on two opposite side walls of the heat dissipation groove. A sliding plate is slidably connected to the two installation grooves. A shielding plate is provided at one end of the two sliding plates facing each other. A plurality of through holes are opened on the shielding plate. Through the setting of the protection mechanism, under the monitoring of the external weather by the rain and snow sensor and the driving action of the driving mechanism, the through holes on the shielding plate are made to communicate or stagger with the heat dissipation holes, ensuring the normal heat dissipation of the LED projection lamp and avoiding external rainwater from entering the circuit board in the housing through the heat dissipation holes, causing a short circuit of the circuit board and resulting in a failure of the LED projection lamp.

[0005] However, the existing processing equipment has the following deficiencies: In the process of using an LED lighting device, mosquitoes are easily affected by phototaxis and enter the interior of the lamp. After mosquitoes enter, it will affect the lighting effect. Their corpses and activities may block the light, making the light emitted by the lamp dim and uneven. On the other hand, mosquitoes may damage the lamp components inside the lamp. Their activities may cause damage to the wires, affecting the stability of the circuit and even posing safety hazards such as short circuits. In addition, cleaning mosquitoes is also rather troublesome, requiring the disassembly of the lamp, which increases the maintenance cost and workload, brings inconvenience to users, and also affects the overall user experience of the LED lighting device.

[0006] Therefore, we propose an LED lighting device with linear dimming drive to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide an LED lighting device with linear dimming drive. Place mothballs and other insect repellent drugs in the material slot, then buckle the cylinder on the placement plate. At this time, the fixed rod is inserted into the magnet, and then the magnet adsorbs the cylinder. Then, when the lamp works, the servo motor starts and drives the fan blade to rotate. While the fan blade rotates, it drives the air flow into the lamp holder to cool and dissipate heat the lamp. At the same time, the hot air blown out is ejected through the nozzle. The nozzle drives the hot air into the cylinder to heat the mothballs and increase the divergence of the mothball smell, facilitating the dispelling of mosquitoes, so as to solve the problems raised in the above background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solution: An LED lighting device with linear dimming drive, comprising: a lamp holder and a lamp; the lamp is installed in the inner wall of the lamp holder, a bracket is arranged on the upper surface of the lamp holder, a protective insect repellent device is arranged on one side of the lamp holder, the protective insect repellent device includes a frame, the frame is fixedly connected to the lamp holder, a servo motor is fixedly connected to the inner wall of the frame, the driving end of the servo motor is fixedly connected to a fan blade, a nozzle is fixedly connected to one side of the lamp holder, a bracket is fixedly connected to the side of the lamp holder close to the nozzle, a placement plate is fixedly connected to the surface of the bracket, and a cylinder is arranged on the upper surface of the placement plate; The inner wall of the cylinder is provided with a replacement component. The replacement component includes a material tank, which is opened in the inner wall of the placing disc. The surface of the placing disc is fixedly connected with a magnet. The lower surface of the cylinder is fixedly connected with an adapter plate, and the surface of the adapter plate is fixedly connected with a fixing rod. By setting up the protection and insect repellent device, insect repellent drugs such as camphor balls are placed in the material tank, and the hot air ejected by the nozzle is used to heat them to accelerate the smell divergence, which can strongly disperse mosquitoes, keep the environment around the lamp clean, reduce the influence on the lighting aesthetics and the performance of the lamp due to the accumulation of mosquito corpses. At the same time, while cooling and dissipating heat of the lamp, the generated air flow can be used to heat the insect repellent drugs, improving the energy utilization efficiency, ensuring the normal heat dissipation of the lamp, extending the service life of the lamp, and enhancing the insect repellent effect.

[0009] Preferably, the nozzle is arranged in an "L" shape and is connected to the inside of the lamp holder. By setting up the nozzle, the nozzle guides the hot air generated when the lamp works into the cylinder. Since the lamp will generate heat during operation, if this heat is not dissipated in time, it may affect the service life and performance of the lamp. Through the nozzle, the hot air is guided from the lamp holder area where the lamp is located to the cylinder where insect repellent drugs such as camphor balls are placed, realizing the effective transfer of heat, and making the heat that may have an adverse effect on the lamp be reasonably utilized.

[0010] Preferably, a filter screen is sleeved on the surface of the nozzle, and the filter screen of the nozzle corresponds to the direction of the cylinder. By setting up the filter screen, it is convenient to protect the nozzle, reduce the possibility of mosquitoes entering through the nozzle, and increase the safety of the equipment.

[0011] Preferably, there are four nozzles, and the four nozzles are arranged in mirror symmetry.

[0012] Preferably, a plurality of air inlets are opened on the surface of the cylinder, and the air inlets on the surface of the cylinder are arranged in a circumferential array. By setting up the cylinder, the cylinder provides a placement space for insect repellent drugs such as camphor balls. After placing the insect repellent drugs in the material tank and buckling the cylinder, the insect repellent drugs can be concentrated in a relatively enclosed space, preventing the drugs from being scattered randomly. At the same time, it is also convenient to manage and replace the drugs as a whole to ensure the continuous and stable insect repellent effect.

[0013] Preferably, a pull ring is fixedly connected to the surface of the cylinder, and a slot is opened on the surface of the magnet. By setting up the magnet, when the cylinder is buckled on the placing disc, the fixing rod is inserted into the magnet, and the magnet adsorbs the cylinder, making the cylinder and the placing disc closely combined, ensuring that the whole device remains stable during the operation of the lamp and will not be loosened or fallen off due to vibration or air flow, guaranteeing the reliability of the device.

[0014] Preferably, the fixing rod is inserted into the slot, the material of the cylinder is iron, and the cylinder is magnetically connected to the magnet. The fixing rod is provided to connect the cylinder to the placement plate. When the cylinder is buckled on the placement plate, the fixing rod is inserted into the magnet, so that the cylinder can be stably fixed on the placement plate. This connection method ensures that during the operation of the lamp, the cylinder will not be easily displaced or fall off due to the influence of airflow or other external forces, thereby ensuring the structural stability of the entire device.

[0015] Preferably, a maintenance assembly is provided on the upper surface of the lamp holder, and the maintenance assembly includes a telescopic rod, which is installed with the bracket, the surface of the bracket is fixedly connected with a plate body, the surface of the plate body is rotatably connected with a driving tooth, one side of the driving tooth is fixedly connected with a winding roller, the surface of the winding roller is fixedly connected with a disk body, the surface of the disk body is sleeved with a rope body, the surface of the plate body is fixedly connected with a DC motor, and the driving end of the DC motor is fixedly connected with a gear. By setting up the maintenance assembly, the convenience of maintenance is improved. When the lamp needs to be maintained, the DC motor can be started to automatically descend to the predetermined position without the aid of complicated climbing equipment or dangerous climbing operations, which greatly reduces the difficulty and risk of maintenance, saves manpower and time costs, enhances safety, provides a safer working environment for maintenance personnel, and can quickly reset the lamp without affecting normal use.

[0016] Preferably, the gear is meshingly connected with the driving teeth, and a matching block is fixedly connected to the upper surface of the lamp holder. By setting the gear, after the DC motor is started, the gear, as a key component of power transmission, transmits the rotational power generated by the motor to the driving teeth. By meshing with the driving teeth, the gear converts the high-speed rotation of the motor into a speed and torque suitable for the rotation of the drive disk, thereby ensuring that the entire system can operate stably.

[0017] Preferably, the side of the rope body away from the disc body is fixedly connected to the matching block, and there are two telescopic rods, which are arranged in a mirror-symmetrical manner. By setting the telescopic rods, during the lifting and lowering process of the lamp, the telescopic rods are extended and retracted as the lamp moves, thereby providing auxiliary support for the lamp. It ensures that the lamp maintains a stable direction when moving up and down, and prevents the lamp from shaking or shifting. This guiding effect enables the lamp to accurately reach the predetermined position for maintenance, and smoothly reset after the maintenance is completed, thereby improving the accuracy and reliability of the entire maintenance process.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a protective insect repellent device and a replacement component. When in use, insect repellents such as camphor balls are placed in a material slot, and then a cylinder is buckled on a placement plate. At this time, a fixing rod is inserted into a magnet, and then the magnet is adsorbed with the cylinder. Then, when the lamp is working, a servo motor is started and simultaneously drives the fan blades to rotate. While the fan blades rotate, airflow is driven into the lamp holder to cool and dissipate the heat of the lamp. At the same time, the blown hot air is ejected through a nozzle, and the nozzle drives the hot air into the cylinder to heat the camphor balls, increase the dissipation of the smell of the camphor balls, and facilitate the dispersal of mosquitoes. By setting the present invention, insect repellents such as camphor balls are placed in the material slot, and the hot air ejected by the nozzle is used to heat them, accelerate the dissipation of the smell, can strongly dissipate mosquitoes, keep the surrounding environment of the lamp clean, reduce the impact on the lighting aesthetics and lamp performance due to the accumulation of mosquito corpses, and at the same time, while cooling and dissipating the lamp, the generated airflow can also be used to heat the insect repellent, thereby improving the utilization efficiency of energy, ensuring the normal heat dissipation of the lamp, extending the service life of the lamp, and enhancing the insect repellent effect.

[0019] 2. The present invention sets a maintenance component. When in use, the DC motor is started to drive the gear to rotate. The gear rotates and drives the driving teeth to rotate at the same time. The driving teeth drive the disk to rotate during the rotation process. At this time, the disk releases the line, the telescopic rod loses its restraint, and the lamp moves downward under the influence of gravity. When it reaches the predetermined position, the DC motor stops rotating. At this time, the lamp can be inspected and maintained. When the inspection is completed, the DC motor reversely drives the gear to drive the disk to reel in the rope body, and the lamp stand is pulled upward by the force, and the telescopic rod contracts, and the lamp stand is reset. By setting the present invention, the convenience of maintenance is improved. When the lamp needs to be inspected and maintained, the DC motor can be started to automatically descend to the predetermined position. There is no need to rely on complex climbing equipment or perform dangerous climbing operations, which greatly reduces the difficulty and risk of maintenance, saves manpower and time costs, enhances safety, provides a safer working environment for maintenance personnel, and can quickly reset the lamp without affecting normal use.

The replacement component 4 includes a material tank 39 which is opened in the inner wall of the placement plate 36. The surface of the placement plate 36 is fixedly connected with a magnet 43. The lower surface of the cylinder 37 is fixedly connected with an adapter plate 45, and the surface of the adapter plate 45 is fixedly connected with a fixing rod 42. By setting the protection and insect repellent device 3, insect repellent drugs such as camphor balls are placed in the material tank 39, and the hot air ejected by the nozzle 34 is used to heat them, accelerating the divergence of the smell, which can strongly disperse mosquitoes, keep the environment around the lamp 2 clean, reduce the influence on the lighting aesthetics and the performance of the lamp 2 caused by the accumulation of mosquito corpses. At the same time, while cooling and dissipating heat from the lamp 2, the generated air flow can also be used to heat the insect repellent drugs, improving the utilization efficiency of energy. It not only ensures the normal heat dissipation of the lamp 2, extends the service life of the lamp 2, but also enhances the insect repellent effect.

[0024] According to Figures 3-5 As shown, the nozzle 34 is arranged in an "L" shape and is internally connected to the lamp holder 1. By setting the nozzle 34, the nozzle 34 guides the hot air generated when the lamp 2 works into the cylinder 37. Since the lamp 2 generates heat during operation, if this heat is not dissipated in time, it may affect the service life and performance of the lamp 2. Through the nozzle 34, the hot air is guided from the area of the lamp holder 1 where the lamp 2 is located to the cylinder 37 where insect repellent drugs such as camphor balls are placed, realizing the effective transfer of heat and making reasonable use of the heat that might otherwise have an adverse effect on the lamp 2.

[0025] According to Figures 3-5 As shown, a filter screen 35 is sleeved on the surface of the nozzle 34, and the position of the filter screen 35 of the nozzle 34 corresponds to the direction of the cylinder 37. By setting the filter screen 35, it is convenient to protect the nozzle 34, reducing the possibility of mosquitoes entering through the nozzle 34 and increasing the safety of the equipment.

[0026] According to Figures 3-5 As shown, there are four nozzles 34, and the four nozzles 34 are arranged in mirror symmetry.

[0027] According to Figures 3-5 As shown, a plurality of air inlets are opened on the surface of the cylinder 37, and the air inlets on the surface of the cylinder 37 are arranged in a circumferential array. By setting the cylinder 37, the cylinder 37 provides a placement space for insect repellent drugs such as camphor balls. After placing the insect repellent drugs in the material tank 39 and buckling the cylinder 37, the insect repellent drugs can be concentrated in a relatively enclosed space, preventing the drugs from being scattered randomly. At the same time, it is also convenient for overall management and replacement of the drugs to ensure the continuous and stable insect repellent effect.

[0028] According to Figures 3-5As shown, a pull ring 41 is fixedly connected to the surface of the cylinder 37, and a slot 44 is provided on the surface of the magnet 43. By setting the magnet 43, when the cylinder 37 is buckled on the placement plate 36, the fixing rod 42 is inserted into the magnet 43. The magnet 43 adsorbs the cylinder 37 so that the cylinder 37 and the placement plate 36 are tightly combined, ensuring that the entire device remains stable during the operation of the lamp 2 and will not loosen or fall off due to vibration or airflow, thereby ensuring the reliability of the device.

[0029] according to Figures 3-5 As shown, the fixing rod 42 is inserted into the slot 44, the material of the cylinder 37 is iron, and the cylinder 37 is magnetically connected to the magnet 43. By setting the fixing rod 42, the fixing rod 42 connects the cylinder 37 to the placement plate 36. When the cylinder 37 is buckled on the placement plate 36, the fixing rod 42 is inserted into the magnet 43, so that the cylinder 37 can be stably fixed on the placement plate 36. This connection method ensures that during the operation of the lamp 2, the cylinder 37 will not be easily displaced or fall off due to the influence of airflow or other external forces, thereby ensuring the structural stability of the entire device.

[0030] according to Figures 6-7 As shown, a maintenance component 5 is provided on the upper surface of the lamp holder 1, and the maintenance component 5 includes a telescopic rod 52, and the telescopic rod 52 is installed with the bracket 6. The surface of the bracket 6 is fixedly connected with a plate body 51, and the surface of the plate body 51 is rotatably connected with a driving tooth 57. One side of the driving tooth 57 is fixedly connected with a winding roller 58, and the surface of the winding roller 58 is fixedly connected with a disk body 59. The surface of the disk body 59 is sleeved with a rope body 53, and the surface of the plate body 51 is fixedly connected with a DC motor 55, and the driving end of the DC motor 55 is fixedly connected with a gear 56. By setting the maintenance component 5, the convenience of maintenance is improved. When the lamp 2 needs to be maintained, the DC motor 55 can be started to automatically descend to the predetermined position without the need for complex climbing equipment or dangerous climbing operations. The difficulty and risk of maintenance are greatly reduced, manpower and time costs are saved, safety is enhanced, and a safer working environment is provided for maintenance personnel. Moreover, the lamp 2 can be quickly reset without affecting normal use.

[0031] according to Figures 6-7 As shown, the gear 56 is meshed with the driving tooth 57, and the upper surface of the lamp holder 1 is fixedly connected with a matching block 54. By setting the gear 56, after the DC motor 55 is started, the gear 56, as a key component of power transmission, transmits the rotational power generated by the motor to the driving tooth 57. By meshing with the driving tooth 57, the gear 56 converts the high-speed rotation of the motor into a speed and torque suitable for the rotation of the drive disk 59, ensuring that the entire system can operate stably.

[0032] according to Figures 6-7As shown, the side of the rope body 53 away from the disc body 59 is fixedly connected to the matching block 54, and there are two telescopic rods 52, which are arranged in a mirror-symmetrical manner. By setting the telescopic rods 52, during the lifting and lowering process of the lamp 2, the telescopic rods 52 are extended and retracted as the lamp 2 moves, providing auxiliary support for the lamp 2, which ensures that the lamp 2 maintains a stable direction when moving up and down, and prevents the lamp 2 from shaking or shifting. This guiding effect enables the lamp 2 to accurately reach the predetermined position for maintenance, and smoothly reset after the maintenance is completed, thereby improving the accuracy and reliability of the entire maintenance process.

[0033] The effect achieved by the whole mechanism is as follows: by setting the protective insect repellent device 3 and the replacement component 4, when in use, the insect repellent such as mothballs is placed in the material slot 39, and then the cylinder 37 is buckled on the placement plate 36, at this time, the fixing rod 42 is inserted into the magnet 43, and then the magnet 43 is adsorbed with the cylinder 37, and then when the lamp 2 is working, the servo motor 32 is started and drives the fan blade 33 to rotate, and the fan blade 33 rotates and drives the air flow into the lamp holder 1 to cool down the lamp 2, and at the same time, the hot air blown out is ejected through the nozzle 34, and the nozzle 34 drives the hot air into the cylinder 3 7, the camphor balls are heated to increase the dissipation of the camphor ball smell, which is convenient for dispersing mosquitoes. By setting the present invention, camphor balls and other insect repellents are placed in the material trough 39, and the hot air ejected from the nozzle 34 is used to heat them, so as to accelerate the dissipation of the smell, and mosquitoes can be strongly dissipated, and the environment around the lamp 2 is kept clean, which reduces the impact of the accumulation of mosquito corpses on the lighting aesthetics and the performance of the lamp 2. At the same time, while cooling and dissipating the lamp 2, the generated airflow can also be used to heat the insect repellent, thereby improving the utilization efficiency of energy, ensuring the normal heat dissipation of the lamp 2, and extending the lamp life. The service life of the lamp 2 is prolonged, and the insect repelling effect is enhanced. By setting the maintenance component 5, when in use, the DC motor 55 is started to drive the gear 56 to rotate. The gear 56 rotates and drives the driving gear 57 to rotate. The driving gear 57 drives the disc 59 to rotate during the rotation. At this time, the disc 59 releases the wire, the telescopic rod 52 loses its restraint, and the lamp 2 moves downward under the influence of gravity. When it reaches the predetermined position, the DC motor 55 stops rotating. At this time, the lamp 2 can be repaired. When the repair is completed, the DC motor 55 reversely drives the gear 57 and the wheel 56 to drive the disc 59 to rotate. The rope body 53 is wound up, and the lamp stand 1 is pulled upward by the force, and at the same time the telescopic rod 52 is contracted, and the lamp stand 1 is reset. By setting the present invention, the convenience of maintenance is improved. When the lamp 2 needs to be repaired, starting the DC motor 55 can automatically lower the lamp 2 to a predetermined position without the aid of complex climbing equipment or dangerous climbing operations, which greatly reduces the difficulty and risk of maintenance, saves manpower and time costs, enhances safety, and provides a safer working environment for maintenance personnel. Moreover, the lamp 2 can be quickly reset without affecting normal use.
