Description

Technical Field

[0001] The invention belongs to the technical field of eye protection lamp ballasts, and particularly relates to a heat-dissipating eye protection lamp ballast. Background Art

[0002] A ballast is a device that limits current and generates an instantaneous high voltage on a fluorescent lamp. It is made by winding enameled wire around an iron core made of silicon steel. Such a coil with an iron core will generate a self-induced high voltage when the power is switched on or off instantaneously, and this high voltage is applied to the electrodes (filaments) at both ends of the fluorescent lamp tube. Since there is always current passing through the ballast during the operation of the fluorescent lamp, it is prone to vibration and heat generation. Therefore, for a fluorescent lamp with a ballast, especially when the quality of the ballast is poor, it is very easy to burn out due to heat generation and long-term use. This phenomenon has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0003] The purpose of the invention is to provide a heat-dissipating eye protection lamp ballast to solve the problems mentioned in the above background art.

[0004] To solve the above technical problems, the invention provides the following technical solution: A heat-dissipating eye protection lamp ballast, including a lamp body. The lamp body includes a lamp pole, a lighting lamp, a base, and a ballast meter. A sliding hole is opened on the upper right side of the base, and the lamp pole is slidably connected in the sliding hole. The lighting lamp is fixedly installed at the upper end of the lamp pole. The ballast meter is fixedly installed at the lower end of the lamp pole and is located inside the base. The ballast meter is electrically connected to an external power supply and is also electrically connected to the lighting lamp. A heat dissipation mechanism is arranged inside the base. The heat dissipation mechanism includes a motor, a rotating shaft, a gear disk, a rotating rod, a gear, two fans, and two hoses. The motor is fixedly installed at the bottom of the inner wall of the base. The rotating shaft is fixedly connected to the output end of the motor. The gear disk is fixedly installed at the upper end of the rotating shaft. The rotating rod is installed on the inner wall of the base through a bearing. The gear is fixedly installed on the outer side of the rotating rod and meshes with the gear disk. The two fans are respectively located on the upper and lower sides of the gear. The upper fan is fixed to the upper surface of the gear through two hoses and is slidably connected to the outer side of the rotating rod. The lower fan is fixedly installed on the outer side of the rotating rod. Heat dissipation holes are arranged on both the upper and lower parts of the base.

[0005] The present invention further illustrates that an extrusion ball is fixedly installed on the outer side of the rotating shaft. On the left side of the inner wall of the base, a hydraulic chamber is fixedly installed. A hydraulic plate is slidably connected to the inner wall of the hydraulic chamber. A hydraulic rod is fixedly installed on the right side of the hydraulic plate. The right end of the hydraulic rod is spherical and is aligned with the extrusion ball. Below the inner wall of the base, a frame is provided. A number of support rods are fixedly installed around the frame. A number of holes are provided at the bottom of the base. The support rods are respectively slidably connected in the holes. Below the middle of the frame, a telescopic rod is fixedly installed. The lower end of the telescopic rod is fixedly connected to the bottom of the inner wall of the base. The telescopic rod is connected to the left side of the hydraulic chamber through a pipeline. Hydraulic oil is filled on the left side of the hydraulic plate and is spring-connected to the left side of the inner wall of the hydraulic chamber.

[0006] The present invention further illustrates that connecting rods are fixedly installed on both the front and rear sides of the ballast. The lower ends of the connecting rods are fixedly connected to the upper surface of the frame.

[0007] The present invention further illustrates that the interiors of both hoses are hollow and filled with magnetorheological fluid. Above the middle of the frame, a fixed rod is fixedly installed. A magnetic block is fixedly installed at the upper end of the fixed rod. The magnetic block is located on one side of the hose. A limiting block is fixed on the outer side of the rotating rod. The limiting block is located between the upper fan and the gear.

[0008] The present invention further illustrates that a gear module is provided inside the ballast, and a speed control module is provided inside the motor. The gear module is electrically connected to the speed control module. The gear module is used for the user to adjust the brightness of the eye protection lamp, thereby judging the magnitude of the current passing through the ballast. The speed control module is used to control the rotation speed of the motor according to the magnitude of the current passing through the ballast.

[0009] The present invention further illustrates that the control methods of the gear module and the speed control module are as follows: , is the real-time rotation speed of the motor, is the maximum rotation speed of the motor, is the magnitude of the current passing through the ballast, is the maximum passing current of the ballast. The greater the current passing through the ballast, the faster the rotation speed of the motor.

[0010] The present invention further illustrates that the rotation speed of the motor is proportional to the telescopic frequency of the telescopic rod.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention dissipates heat through heat dissipation holes. At the same time, when the motor operates, it drives the rotation of the rotating shaft, the rotating shaft drives the rotation of the gear disk, the gear disk drives the rotation of the gear through meshing, the gear drives the rotation of two fans through the rotating rod. After the fans rotate, the heat dissipation efficiency inside the base is accelerated, thereby improving the heat dissipation effect, fully avoiding the ballast from being burned due to excessive heating temperature, and thus playing a role in protecting the eye protection lamp;

[0012] Moreover, the frame drives the support rod at the bottom to move up and down. When the support rod moves downward, the base is lifted, so that the space below the heat dissipation holes at the bottom increases. When the fan blows air for heat dissipation, the heat dissipation effect inside the base is further improved, thereby further protecting the ballast, and the heat dissipation effect is greatly enhanced. When the frame moves downward, the support rod moves downward. Through relative movement, the base is raised, and the synchronous lighting lamp moves downward, so that the position height of the lighting lamp can be kept unchanged, avoiding the influence on the lighting effect caused by the change of the position height of the lighting lamp while improving the heat dissipation effect.

Detailed implementation manners

[0023] The technical solution of the present invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-8 , the present invention provides a technical solution: a heat-dissipating eye-protecting lamp ballast, including a lamp body, the lamp body includes a lamp post 1, an illuminating lamp 2, a base 3, and a ballast 4. A sliding hole is opened on the upper right side of the base 3, and the lamp post 1 is slidably connected in the sliding hole. The illuminating lamp 2 is fixedly installed at the upper end of the lamp post 1, and the ballast 4 is fixedly installed at the lower end of the lamp post 1 and is located inside the base 3. The ballast 4 is electrically connected to an external power supply and is electrically connected to the illuminating lamp 2;

[0025] A heat dissipation mechanism is provided inside the base 3, and the heat dissipation mechanism includes a motor 31, a rotating shaft 32, a gear disk 33, a rotating rod 34, a gear 341, two fans 342, and two hoses 343;

[0026] The motor 31 is fixedly installed at the bottom of the inner wall of the base 3, the rotating shaft 32 is fixedly connected to the output end of the motor 31, the gear disk 33 is fixedly installed at the upper end of the rotating shaft 32, the rotating rod 34 is installed on the inner wall of the base 3 by bearings, the gear 341 is fixedly installed on the outside of the rotating rod 34 and meshes with the gear disk 33. The two fans 342 are respectively located above and below the gear 341. The upper fan 342 is fixed to the upper surface of the gear 341 through two hoses 343 and is slidably connected to the outside of the rotating rod 34. The lower fan 342 is fixedly installed on the outside of the rotating rod 34;

[0027] Heat dissipation holes 35 are provided on both the upper and lower sides of the base 3;

[0028] Electric current enters the lighting lamp 2 through the ballast 4, causing the lighting lamp 2 to emit light. The ballast 4 operates to generate high temperature, and the temperature is dissipated through the heat dissipation holes 35 for heat dissipation. At the same time, the motor 31 operates to drive the rotating shaft 32 to rotate. The rotating shaft 32 drives the gear disk 33 to rotate. The gear disk 33 drives the gear 341 to rotate through meshing. The gear 341 drives two fans 342 to rotate through the rotating rod 34. After the fans 342 rotate, the heat dissipation efficiency inside the base 3 is increased, thereby improving the heat dissipation effect, fully avoiding the ballast 4 from being burned due to overheating, and thus playing a role in protecting the eye-protecting lamp.

[0029] A squeezing ball 321 is fixedly installed on the outer side of the rotating shaft 32. The left side inner wall of the base 3 is fixedly installed with a hydraulic chamber 36. The inner wall of the hydraulic chamber 36 is slidably connected with a hydraulic plate 361. The right side of the hydraulic plate 361 is fixedly installed with a hydraulic rod 362. The right end of the hydraulic rod 362 is spherical and is aligned with the squeezing ball 321.

[0030] Below the inner wall of the base 3, there is a frame 37. 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. The plurality of support rods 371 are respectively slidably connected in the holes. The lower middle part of the frame 37 is fixedly installed with a telescopic rod 372. The lower end of the telescopic rod 372 is fixed to the inner wall bottom of the base 3.

[0031] The telescopic rod 372 is connected to the left side of the hydraulic chamber 36 through a pipeline. The left side of the hydraulic plate 361 is filled with hydraulic oil and is spring-connected to the left side inner wall of the hydraulic chamber 36.

[0032] Through the above steps, during the rotation of the rotating shaft 32, the squeezing ball 321 is driven to rotate around its center. The squeezing ball 321 comes into contact with and squeezes the right end of the hydraulic rod 362. The hydraulic rod 362 is forced to push the hydraulic plate 361 to slide leftward along the inner wall of the hydraulic chamber 36, and the spring deforms under force. Then, the liquid on the left side of the hydraulic plate 361 is squeezed and enters the telescopic rod 372 through the pipeline, thereby causing the telescopic rod 372 to extend. 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. During the reset process, the liquid in the telescopic rod 372 is drawn out, causing the telescopic rod 372 to perform telescopic motion. When the telescopic rod 372 expands and contracts, it drives the frame 37 to move up and down. The frame 37 drives the support rods 371 at the bottom to move up and down. When the support rods 371 move downward, the base 3 is lifted, so that the space below the heat dissipation holes 35 at the bottom is increased. When the fan 342 blows air for heat dissipation, the heat dissipation effect inside the base 3 is further improved, thereby further protecting the ballast 4, and the heat dissipation effect is greatly enhanced.

[0033] Connecting rods 41 are fixedly installed on both the front and rear sides of the ballast 4. The lower ends of the connecting rods 41 are fixedly connected to the upper surface of the frame 37.

[0034] When the frame 37 moves up and down, the base 3 rises and then falls. At this time, the frame 37 pulls the ballast 4 to move through the connecting rod 41, and the ballast 4 drives the lighting lamp 2 to move up and down through the lamp post 1. When the frame 37 moves downward, the support rod 371 moves downward. Through relative movement, the base 3 rises, and the lighting lamp 2 moves downward synchronously, so that the position height of the lighting lamp 2 can be kept unchanged, avoiding the influence on the lighting effect caused by the change of the position height of the lighting lamp 2 while improving the heat dissipation effect.

[0035] The interiors of both of the two hoses 343 are hollow and filled with magnetorheological fluid.

[0036] A fixing rod 373 is fixedly installed above the middle of the frame 37, and a magnetic block 374 is fixedly installed at 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 to the outside of the rotating rod 34, and the limiting block 344 is located between the upper fan 342 and the gear 341.

[0037] When the frame 37 moves downward, the magnetic block 374 is driven to move downward through the fixing rod 373. When the position of the magnetic block 374 is at 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 magnetic block 374 moves downward and moves 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 self-weight of the fan 342 causes it to slide downward through the rotating rod 34, so that the blowing area of the upper fan 342 is wider, and the heat dissipation efficiency is greatly enhanced.

[0038] A gear module is arranged inside the ballast 4, and a speed control module is arranged inside the motor 31. The gear module is electrically connected to the speed control module. The gear module is used for the user to adjust the brightness of the eye protection lamp, so as to judge the magnitude of the current passing through the ballast 4. The speed control module is used to control the speed of the motor 31 according to the magnitude of the current passing through the ballast 4.

[0039] The control methods of the gear module and the speed control module are as follows: , is the real-time speed of the motor 31, is the maximum speed of the motor 31, is the magnitude of the current passing through the ballast 4, is the maximum passing current of the ballast 4. The greater the current passing through the ballast 4, the faster the speed of the motor 31;

[0040] For the ballast 4, when the current passing through it is large, the temperature increases, which makes the rotation speed of the motor 31 faster, thus fully ensuring the heat dissipation effect. For the ballast 4, when the current passing through it 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.

[0041] The rotation speed of the motor 31 is proportional to the telescopic frequency of the telescopic rod 372;

[0042] Through the above steps, when the rotation speed of the motor 31 is fast, the telescopic frequency of the telescopic rod 372 is accelerated, and the frequency of the heat dissipation holes 35 at the bottom of the base 3 moving up and down is high, which can fully accelerate heat dissipation. After the rotation speed of the motor 31 decreases, while ensuring heat dissipation, it avoids the frequency of the base 3 shaking up and down being always high, thus affecting the user's attention.

[0043] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0044] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
