Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to an LED lighting protection device. Background Technology

[0002] LED lights are lighting devices that use light-emitting diodes as their light source. They utilize the electroluminescence principle of semiconductor materials, where electrons and holes recombine to generate photons when current passes through them, thus emitting light. Compared to traditional lighting fixtures, LED lights have advantages such as high efficiency and energy saving, long lifespan, small size, fast response speed, rich colors, and dimming. They are widely used in indoor and outdoor lighting, landscape lighting, display screens, automotive lighting, and many other fields, and are one of the important development directions of modern lighting technology.

[0003] LED lights used in humid environments are typically protected with sealed housings to prevent moisture intrusion and corrosion of the internal structure. However, while this sealed structure effectively blocks moisture, it also presents a heat dissipation challenge. Although the heat generated by LED lights is relatively small, the internal heat is difficult to dissipate in a sealed environment and tends to accumulate, leading to an increase in the light fixture temperature. This not only reduces the luminous efficiency and lifespan of the LED lights but may also pose safety hazards, thus weakening the overall protective effect of the sealed structure. Therefore, an LED light fixture protection device is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figures 1-7 This utility model provides a technical solution:

[0029] An LED lighting fixture protection device includes a PCB connecting board 1 and connecting lines 2. A lamp housing assembly 3 is fixedly connected to the outside of the PCB connecting board 1. A protective component 4 is fixedly connected to the front end of the lamp housing assembly 3 by bolts. A glass plate 5 is fixedly connected to the inside of the protective component 4. An LED bead 6 is fixedly connected to the front end of the PCB connecting board 1. The protective component 4 includes a frame plate 41. A hollow shell 42 is fixedly connected to the inside of the frame plate 41. A flow groove 43, a fixing port 44, and a pressure relief hole 45 are provided on the inside of the hollow shell 42. A rubber sheet 46 is fixedly connected to the inside of the pressure relief hole 45. A copper tube 47 is fixedly connected to the inside of the fixing port 44. An internal channel 48 is provided on the inside of the copper tube 47. A filter plate 49 is fixedly connected to the inside of the hollow shell 42. The inside of the hollow shell 42 is fixedly connected to the outside of the glass plate 5.

[0030] As a further implementation of this solution, the lamp housing assembly 3 includes a lamp rear cover 31, a front fixing seat 32 is fixedly connected to the front end of the lamp rear cover 31, a sealing ring 33 is fixedly connected to the front end of the front fixing seat 32, and an embedding groove 34 is provided on the inner side of the front fixing seat 32. Through the above-mentioned configuration, this structural design provides a basis for the installation and sealing of subsequent components, ensuring the overall stability and sealing of the device.

[0031] As a further implementation of this solution, a wire hole is provided on the inner side of the lamp cover 31 near the connecting line 2. The connecting line 2 is inserted into the wire hole of the lamp cover 31. The wire hole of the lamp cover 31 is fixed to the connecting line 2 by sealant. The inner side of the lamp cover 31 is fixedly connected to the connecting line 2. Through the above settings, the fixing method of the wire hole and sealant not only ensures the stable connection of the wire, but also effectively prevents moisture from entering the device through the wire, thereby enhancing the moisture-proof performance and reliability of the device.

[0032] As a further implementation of this solution, the frame plate 41 is fixedly connected to the front fixed seat 32 by bolts, the rear end of the hollow shell 42 is tightly attached to the front end of the sealing ring 33, and the rear end of the hollow shell 42 is embedded in the interior of the mounting groove 34. Through the above settings, structural protection is provided to prevent moisture intrusion and fix the internal components.

[0033] As a further implementation of this solution, the rubber sheet 46 is set inside the mounting groove 34. Both the rubber sheet 46 and the copper tube 47 are located at the rear end of the glass plate 5. The hollow shell 42 is sealed to the glass plate 5 with sealant. Fixing ports 44 are opened at the upper and lower ends of the hollow shell 42. The upper and lower ends of the copper tube 47 are fixed to the inside of the fixing ports 44. The copper tube 47 extends into the interior of the flow groove 43. The built-in channel 48 is connected to the flow groove 43. Through the above arrangement, this design enables the copper tube 47 to effectively absorb and conduct heat. By communicating with the outside air, the heat is quickly dissipated, effectively solving the heat dissipation problem in a sealed environment and extending the service life of the device.

[0034] As a further implementation of this solution, the rear end of the copper tube 47 is attached to the front end of the PCB connecting board 1, and the copper tube 47 is placed between the LED beads 6. Through the above arrangement, the close contact between the copper tube 47, the PCB connecting board 1, and the LED beads 6 ensures that heat can be quickly conducted from the LED beads 6 and related components to the heat dissipation components, thereby improving heat dissipation efficiency and reducing the impact of heat on internal components, further enhancing the stability and safety of the device.

[0035] Workflow: When assembling the device, place the copper tube 47 inside the lamp rear cover 31 through the inside of the front fixing seat 32, and align the frame plate 41 with the threaded hole of the front fixing seat 32. After the rear end of the hollow shell 42 is in contact with the front end of the sealing ring 33, fix the frame plate 41 and the front fixing seat 32 with bolts. At this time, the copper tube 47 is between multiple LED beads 6, and the copper tube 47 will contact the inner wall of the lamp rear cover 31 and the front end of the PCB connecting board 1. The lamp rear cover 31 and the connecting line 2 are pre-fixed with sealant. At this time, the installation is completed. The sealing ring 33 seals the hollow shell 42 and the front fixing seat 32, and the rear end of the lamp rear cover 31 is sealed. The inside of the installed device is in a sealed state, which can prevent moisture in the humid environment from entering the inside of the device and causing corrosion damage to the PCB connecting board 1 and LED beads 6, thereby improving the safety of the device.

[0036] When the LED lamp is in use, the LED beads 6 and the PCB connecting board 1 will generate a certain amount of heat. Since the inside of the device is in a sealed state, the air inside the device will expand to a certain extent. When the air inside the lamp rear cover 31 and the front fixing seat 32 expands, the rubber sheet 46 is affected by the expansion of the gas and deforms. The rubber sheet 46 moves into the flow groove 43, thereby relieving the pressure inside the lamp rear cover 31 and the front fixing seat 32. This significantly reduces the deformation of the lamp rear cover 31 and the front fixing seat 32 caused by the expansion of the device, which would lead to poor sealing performance. When the LED beads 6 and the PCB connecting board 1 heat up... The copper tube 47 absorbs the emitted heat, thus dissipating heat from the inside of the device. The copper tube 47 is connected to the outside air through the flow groove 43. The heat inside the copper tube 47 can be dissipated to the outside through the built-in channel 48. At the same time, the outside air can also enter the flow groove 43 through the filter plate 49 and then enter the inside of the built-in channel 48, thereby cooling the copper tube 47. The filter plate 49 filters impurities in the air, thus continuously cooling the device and preventing the device from being damaged due to excessive heat accumulation over a long period of time. This also further improves the practical safety of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
