[0002] The ballast is a device that limits current and generates instantaneous high voltage on a fluorescent lamp. It is made of an iron core made of silicon steel and enameled wire. When the power is turned on / off instantly, the coil with the iron core will generate high voltage by itself, which is applied to the electrodes (filaments) at both ends of the fluorescent lamp. Since the ballast always has current passing through it when the fluorescent lamp is working, it is easy to vibrate and generate heat. Therefore, fluorescent lamps with ballasts, especially those with poor quality ballasts, are easy to burn out due to heat and long-term use. This phenomenon has become a problem that people in this field need to solve urgently. Summary of the invention

The operation of the ballast 4 generates high temperature, and the temperature is dissipated through the heat dissipation holes 35 for heat dissipation. At the same time, the motor 31 runs, driving the shaft 32 to rotate, the shaft 32 drives the gear plate 33 to rotate, the gear plate 33 drives the gear 341 to rotate through meshing, the gear 341 drives two fans 342 to rotate through the rotating rod 34, and after the fan 342 rotates, the heat dissipation efficiency inside the base 3 is accelerated, thereby improving the heat dissipation effect, and fully avoiding the ballast 4 from being burned due to excessive heating, thereby playing a role in protecting the eye protection lamp.

[0015] A squeezing ball 321 is fixedly installed on the outer side of the rotating shaft 32, a hydraulic chamber 36 is fixedly installed on the left side of the inner wall of the base 3, a hydraulic plate 361 is slidably connected to the inner wall of the hydraulic chamber 36, a hydraulic rod 362 is fixedly installed on the right side of the hydraulic plate 361, and the right end of the hydraulic rod 362 is spherical and aligned with the squeezing ball 321; A frame 37 is provided below the inner wall of the base 3, and a plurality of support rods 371 are fixedly installed around the frame 37. A plurality of holes are provided at the bottom of the base 3, and the plurality of support rods 371 are slidably connected in the holes respectively. A telescopic rod 372 is fixedly installed below the middle of the frame 37, and the lower end of the telescopic rod 372 is fixed to the bottom of the inner wall of the base 3; The telescopic rod 372 is connected to the left pipeline of the hydraulic chamber 36, and the left side of the hydraulic plate 361 is filled with hydraulic oil and is connected to the left spring of the inner wall of the hydraulic chamber 36; Through the above steps, the rotation of the rotating shaft 32 drives the squeezing ball 321 to rotate around its center, the squeezing ball 321 and the right end of the hydraulic rod 362 contact and squeeze each other, the hydraulic rod 362 is forced to push the hydraulic plate 361 to slide to the left along the inner wall of the hydraulic chamber 36, the spring is deformed by force, and then the liquid on the left side of the hydraulic plate 361 is squeezed and enters the telescopic rod 372 through the pipeline, so that the telescopic rod 372 is extended, when the squeezing ball 321 rotates to disengage from the hydraulic rod 362, the spring generates a reaction force to reset the hydraulic plate 361, and the liquid in the telescopic rod 372 is extracted during the resetting process, so that the telescopic rod 372 performs telescopic movement, and the telescopic rod 372 drives the frame 37 to move up and down when the telescopic rod 372 is extended and retracted, and the frame 37 drives the bottom support rod 371 to move up and down, and when the support rod 371 moves downward, the base 3 is lifted, so that the space below the heat dissipation hole 35 at the bottom thereof is increased, and when the fan 342 blows air to dissipate heat, the heat dissipation effect inside the base 3 is further improved, thereby further protecting the ballast 4, and the heat dissipation effect is greatly improved.

[0016] The ballast 4 is fixedly mounted with connecting rods 41 on both the front and rear sides, and the lower end of the connecting rod 41 is fixed to the upper surface of the frame 37; When the frame 37 moves up and down, the base 3 is lifted and then lowered. At this time, the frame 37 pulls the ballast 4 to move through the connecting rod 41, and the ballast 4 drives the lamp 2 to move up and down through the lamp pole 1. When the frame 37 moves downward, the support rod 371 moves downward. Through relative movement, the base 3 is raised and the lamp 2 moves downward synchronously, so that the position height of the lamp 2 can remain unchanged, avoiding the change in the position height of the lamp 2 while improving the heat dissipation effect, which affects the lighting effect.

[0017] The interiors of the two hoses 343 are both hollow and filled with magnetorheological fluid; A fixing rod 373 is fixedly installed in the middle upper part of the frame 37, and a magnetic block 374 is fixedly installed on the upper end of the fixing rod 373. The magnetic block 374 is located on one side of the hose 343. A limiting block 344 is fixed on the outer side of the rotating rod 34, and the limiting block 344 is located between the upper fan 342 and the gear 341. When the frame 37 moves downward, the fixed rod 373 drives the magnet 374 to move downward. When the magnet 374 is in the initial position, its magnetic force acts on the magnetorheological fluid, making it a viscous liquid. The supporting force of the hose 343 supports the fan 342. When the magnet 374 moves downward and away from the hose 343, the influence on the magnetorheological fluid inside it is reduced, and the magnetorheological fluid becomes liquid. At this time, the supporting force of the hose 343 is reduced, and the weight of the fan 342 itself causes it to slide downward through the rotating rod 34, so that the upper fan 342 has a wider blowing area, thereby greatly enhancing the heat dissipation efficiency.

[0018] A gear module is provided inside the ballast 4, and a speed control module is provided inside the motor 31. The gear module is electrically connected to the speed control module. The gear module is used to determine the current passing through the ballast 4 by allowing the user to adjust the brightness of the eye protection lamp, and the speed control module is used to control the speed of the motor 31 according to the current passing through the ballast 4.

[0019] The control method of the gear module and the speed control module is: , is the real-time speed of the motor 31, is the maximum speed of the motor 31, is the current passing through the ballast 4, is the maximum current passing through the ballast 4. The greater the current passing through the ballast 4, the faster the rotation speed of the motor 31. When the current passing through the ballast 4 is large, the temperature increases, thereby accelerating the rotation speed of the motor 31, thereby fully ensuring the heat dissipation effect. When the current passing through the ballast 4 is small, the temperature is low, which not only ensures heat dissipation but also reduces the energy consumption of the motor 31, thereby reducing the overall energy consumption of the eye protection lamp and saving costs.

[0020] The rotation speed of the motor 31 is proportional to the extension and retraction frequency of the telescopic rod 372; Through the above steps, when the motor 31 rotates at a high speed, the extension and retraction frequency of the telescopic rod 372 is accelerated, and the heat dissipation holes 35 at the bottom of the base 3 fluctuate up and down at a high frequency, which can fully accelerate the heat dissipation. After the speed of the motor 31 is reduced, while ensuring the heat dissipation, it prevents the base 3 from shaking up and down at a high frequency at all times, thereby preventing the user's attention.
