Technical Field

[0001] The present invention relates to the technical field of LED lighting, and particularly to an LED lighting lamp. Background Art

[0002] An LED lighting lamp is a lighting device that uses light-emitting diodes (LEDs for short) as the light source. An LED is a semiconductor device that emits light when an electric current passes through it. The principle is that energy is released when electrons and holes recombine in the semiconductor material, and this energy is emitted in the form of light. LED lighting has many advantages, such as high efficiency, energy saving, long life, instant-on, strong earthquake resistance, small size, less heat generation, and environmental protection. The current development trends in the LED lighting industry include: Intelligence: Combining with Internet of Things technology to achieve remote control and automated management. Low-carbon environmental protection: Improving energy efficiency and reducing carbon emissions to meet the requirements of green and sustainable development. Application of new technologies: Development of cutting-edge technologies such as MicroLED and ultraviolet LEDs. Design innovation: Paying more attention to product design to meet aesthetic and personalized needs. Quality and stability: With the intensification of market competition, enterprises pay more attention to the quality and reliability of products.

[0003] Currently, when an LED lighting lamp is working, it will generate heat. If the heat cannot be dissipated in time, it may cause the chip junction temperature to rise, thereby affecting the luminous efficiency and reliability. Existing LED lighting lamps generally use natural heat dissipation to dissipate the temperature generated during chip operation. However, the natural heat dissipation method has low heat dissipation efficiency and still results in heat accumulation. Although there is a method of using heat dissipation fins for heat dissipation, a large amount of dust will adhere to the outer surface of the heat dissipation fins, affecting the heat dissipation efficiency, thus affecting the luminous efficiency of the LED lighting lamp, and also increasing infrared thermal radiation, which causes harm to the skin and retina of users. Based on this, an LED lighting lamp is proposed. Summary of the Invention

[0034] Embodiment:

[0035] Refer to Figures 1 - 5 , Figure 7 , Figure 8, an LED lighting lamp, comprising an LED lamp housing 1, an LED lamp cover 3, a light-transmitting cover 4, LED lamp beads 5, an electrical box 6 and an electrical board 7. A mounting plate 2 is fixedly connected to the top of the LED lamp housing 1. The LED lamp cover 3 is fixedly connected to the bottom of the LED lamp housing 1. The electrical box 6 is installed at the inner bottom of the LED lamp housing 1. The electrical board 7 is installed at the inner bottom of the electrical box 6. The light-transmitting cover 4 is installed inside the LED lamp housing 1 and is located at the bottom of the electrical box 6. The LED lamp beads 5 are installed on the electrical board 7. It further comprises an adjusting air cylinder 8 fixedly connected to the top of the electrical box 6. The output end of the adjusting air cylinder 8 is fixedly connected to a piston plate 9. Among them, a piston cylinder 10 is fixedly connected to the electrical box 6. An adjusting sliding bin 11 is fixedly connected to the piston cylinder 10. An adjusting push-pull rod 12 is slidably connected inside the adjusting sliding bin 11. An adjusting groove 13 is formed on the adjusting push-pull rod 12. The number of the LED lamp beads 5 is nine. One of them is installed at the center position of the bottom of the electrical board 7. The other eight are connected to the electrical board 7 through adjusting balls 15. The top of the LED lamp bead 5 is fixedly connected to an adjusting ball 15. The top of the adjusting ball 15 is fixedly connected to an adjusting column 14. The piston plate 9 is slidably connected inside the piston cylinder 10. The adjusting column 14 is slidably connected inside the adjusting groove 13. The adjusting ball 15 is rotatably connected to the electrical board 7.

[0036] During use, first install this LED lighting lamp on a bracket or a wall through the mounting plate 2, and then the power can be turned on for use. When it is necessary to adjust the angle of the LED lamp beads 5 according to the usage requirements so that this LED lighting lamp has different light propagation characteristics, when it is necessary to expand the lighting range, start the adjusting air cylinder 8 to make the adjusting air cylinder 8 extend. As a result, the piston plate 9 slides upward inside the piston cylinder 10, causing the piston cylinder 10 to extract the gas inside the adjusting sliding bin 11, making the adjusting push-pull rod 12 slide into the adjusting sliding bin 11. Then, through the adjusting groove 13, the adjusting column 14 drives the adjusting ball 15 to rotate clockwise, making the LED lamp beads 5 rotate outward, making the light concentration of this LED lighting lamp worse, so as to achieve the purpose of expanding the lighting range. When it is necessary to focus the light to improve the light intensity at the center point, start the adjusting air cylinder 8 to make the adjusting air cylinder 8 shorten. As a result, the piston plate 9 slides downward inside the piston cylinder 10, causing the gas inside the piston cylinder 10 to enter the adjusting sliding bin 11 under the extrusion of the piston plate 9, making the adjusting push-pull rod 12 slide out of the adjusting sliding bin 11. Then, through the adjusting groove 13, the adjusting column 14 drives the adjusting ball 15 to rotate counterclockwise, making the LED lamp beads 5 rotate inward, making the light of this LED lighting lamp gather inward, so as to achieve the purpose of focusing the light to improve the light intensity at the center point.

[0037] The angle of the LED lamp beads 5 is adjusted, enabling this LED lighting lamp to perform focusing or defocusing operations according to usage requirements, and expanding the usage range of this LED lighting lamp.

[0038] Refer toFigures 3 - 8 It further includes: an air extraction cylinder 16 fixedly connected inside the LED lamp housing 1, an air extraction pipe 20 fixedly connected to the air extraction cylinder 16, a dust-proof net 21 fixedly connected to the intake end of the air extraction pipe 20, an exhaust pipe 22 fixedly connected to the bottom of the air extraction cylinder 16, and the exhaust pipe 22 is fixedly connected to the top of the electrical box 6. It also includes a driving motor 17 installed inside the air extraction cylinder 16, the output end of the driving motor 17 is fixedly connected to a rotating shaft 18, an air extraction blade 19 is fixedly connected to the rotating shaft 18, and the bottom of the rotating shaft 18 is rotatably connected to the inner bottom of the air extraction cylinder 16. It further includes a circulation chamber 25 fixedly connected inside the LED lamp housing 1, a circulation groove 27 is formed inside the side wall of the LED lamp housing 1, the circulation chamber 25 is communicated with the circulation groove 27 through a circulation hole 26, a blowing pipe 28 is fixedly connected to the bottom of the LED lamp housing 1, the blowing pipe 28 is communicated with the circulation groove 27, an intake hole 24 is formed at the bottom of the circulation chamber 25.

The exhaust end of the blowing pipe 28 is disposed facing the light-transmitting cover 4. The heat dissipation fins 29 penetrate through the circulation chamber 25 and the circulation groove 27 and are fixedly connected to the circulation chamber 25.

[0039] When the LED lighting lamp is working, it is initially cooled through the heat dissipation fins 29, and then the driving motor 17 is started to make the rotating shaft 18 drive the air extraction blade 19 to rotate, generating a suction force to draw external air into the air extraction cylinder 16 through the air extraction pipe 20. The external air first passes through the dust-proof net 21 before entering the air extraction pipe 20, and the dust-proof net 21 filters the dust in the air to prevent external dust from entering the space formed by the electrical box 6 and the electrical board 7 and adhering to the electrical components in this space, resulting in a short-circuit phenomenon of the electrical components under the action of the dust, providing good protection for the LED lighting lamp and extending the service life of the LED lighting lamp. Only the filtered air will enter the air extraction cylinder 16, and under the action of the exhaust pipe 22, it will enter the space formed by the electrical box 6 and the electrical board 7 from multiple directions to cool the chips and circuit components in this space. Then, the air entering this space will enter the space formed by the bottom of the light-transmitting cover 4 and the electrical box 6 through the exhaust hole 23 to cool the LED lamp beads 5 in this space and simultaneously reduce the temperature in this space, achieving the purpose of reducing the light temperature. Then, the air in this space will enter the circulation chamber 25 through the intake hole 24 to dissipate heat from the heat dissipation fins 29 and improve the heat dissipation efficiency of the heat dissipation fins 29. The air entering the circulation chamber 25 will enter the circulation groove 27 through the circulation hole 26 and then be blown towards the bottom of the light-transmitting cover 4 through the blowing pipe 28 to clean the light-transmitting cover 4;

[0040] It realizes the cooling of the chips in the space composed of the electrical box 6 and the electrical board 7, reduces the junction temperature of the chips, ensures the luminous efficiency and reliability of the LED lamp beads 5, and reduces the temperature of the light, reduces the generation of infrared rays, thereby reducing infrared thermal radiation, well protects the skin of the user, and reduces the harm brought by infrared rays to the user's retina. In addition, it can also cool the heat dissipation fins 29, so that the heat dissipation fins 29 can dissipate more heat of the LED lighting lamp, improves the heat dissipation efficiency of the LED lighting lamp, and at the same time prevents dust from adhering to the light-transmitting cover 4 and affecting the lighting intensity of the LED lighting lamp, and prevents the light-transmitting cover 4 from being corroded due to the long-term adhesion of dust, well protects the light-transmitting cover 4, and extends the service life of the light-transmitting cover 4.

[0042] When the rotating shaft 18 rotates, it will drive the first bevel gear 30 to rotate, and then drive the connecting shaft 32 to rotate through the second bevel gear 31, so that the cleaning frame 34 drives the cleaning brush plate 35 to rotate along the air inlet side of the dust-proof net 21, and clears the dust attached to the air inlet side of the dust-proof net 21, ensuring the air intake efficiency in the air extraction pipe 20, and thus ensuring the heat dissipation efficiency of the internal electrical components of the LED lighting lamp.

[0047] During the up and down sliding of the cleaning ring 41, the magnetic attraction column 43 and the magnetic attraction plate 36 will intermittently coincide, so that the cleaning brush plate 35 slides back and forth in the cleaning frame 34 under the action of the magnetic force between the magnetic attraction column 43 and the magnetic attraction plate 36 and the elastic force of the connecting spring 37, hitting the cleaning frame 34 to generate vibration;
