Description

Technical Field

[0001] This utility model relates to the field of LED bulb technology, specifically to an LED bulb with a protective cover to prevent silicone grease contamination. Background Technology

[0002] LED bulbs, or light-emitting diode bulbs, are a new type of lighting product that uses semiconductor materials as the light source. Based on the electroluminescence principle of semiconductor PN junctions, when current passes through a semiconductor chip, electrons and holes recombine, releasing energy to produce photons, thus emitting light. Compared to traditional incandescent and fluorescent lamps, LED bulbs have significant advantages: they greatly reduce replacement frequency, are flicker-free, emit no ultraviolet or infrared radiation, effectively protecting eyesight, and contain no harmful substances such as mercury, conforming to environmental protection principles. They also feature fast response, compact size, rich colors, and intelligent dimming and color adjustment capabilities, making them widely used in home lighting, commercial spaces, and outdoor landscaping, and an ideal choice for lighting in the era of energy conservation and environmental protection.

[0003] For example, patent CN104696758B discloses a wide-angle LED bulb, belonging to the field of LED technology. It includes a lamp holder, a heat sink, an LED chip, and a substrate. The LED chip is mounted on the substrate, and reflectors are positioned on both sides of the LED chip. These reflectors have a hollow structure, forming an internal cavity. An opening is provided on the side of the reflector facing the LED chip. A heat dissipation cavity is located below the substrate and is connected to the internal cavity. A fan is installed within the heat dissipation cavity. However, in use, the current bulb's mounting structure lacks stability, and long-term use can easily lead to loosening and detachment. Furthermore, the device's sealing performance is poor, allowing dust, silicone grease, and other impurities in the air to easily penetrate the interior, accelerating the aging process of the LED chip and significantly shortening the bulb's lifespan.

[0004] Therefore, in order to solve this problem, we propose an LED bulb with a protective cover to prevent silicone grease contamination. Summary of the Invention

[0005] The purpose of this invention is to provide an LED bulb with an anti-silicone grease contamination protective cover, in order to solve the problems mentioned in the background art. In the current device, the installation structure of the bulb is not stable enough during use, and it is easy to loosen and fall off after long-term use. At the same time, the device has poor sealing performance, and dust, silicone grease and other impurities in the air can easily penetrate into the interior, accelerating the aging process of the LED chip and significantly shortening the life of the bulb.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an LED bulb with an anti-silicone grease contamination protective cover, including a support, a disc at the top of the support, side grooves evenly formed around the disc, U-shaped blocks fixedly connected in the side grooves, sliding grooves formed on the inner wall of the disc, a limiting rod fixedly connected in the sliding groove, a slider movably connected to the limiting rod, a fixing block fixedly connected between the sliders, a spring fixedly connected to the inner wall of the fixing block, a locking block fixedly connected to the side of the fixing block away from the spring, and a first annular body fixedly connected to the top of the disc, with locking grooves evenly formed on the inner wall of the first annular body.

[0007] Furthermore, the engaging block is located within the engaging groove, and the disk and the first annular body are engaged and connected via the engaging block and the engaging groove.

[0008] Furthermore, a second annular body is fixedly connected to the top of the first annular body, and a groove is provided at the bottom of the second annular body, in which an airbag is fixedly connected.

[0009] Furthermore, a mounting base is fixedly connected to the top of the disc, a first sleeve is fixedly connected to the top of the mounting base, and a lamp wick is fixedly connected inside the first sleeve on the top surface of the mounting base.

[0010] Furthermore, a cover is provided on the top of the lamp wick, and a second sleeve is fixedly connected to the bottom of the cover.

[0011] Furthermore, the inner wall of the second sleeve is provided with a threaded groove, and the second sleeve is threadedly connected to the first sleeve.

[0012] Furthermore, the sliders on both sides of the fixed block are located in the grooves opened on the U-shaped block, and the fixed block and the U-shaped block are slidably connected through the sliders and the grooves. The left side of the spring on the inner side of the fixed block is fixedly connected to the inner wall of the U-shaped block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the LED bulb with an anti-silicone grease contamination protective cover adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The LED bulb with anti-silicone grease contamination protective cover, through the precise engagement of the locking block and the locking groove, supplemented by the elastic buffer support of the spring and the slider limiting structure of the U-shaped block and the fixed block, forms a mechanically interlocked and stable connection between the disc and the first ring body. It can effectively resist the loosening of components caused by vibration, external force collision and other factors during long-term use, avoid the risk of the lamp core and the cover falling off, and fundamentally solve the technical pain point of insufficient stability of the existing device installation structure.

[0015] (2) The LED bulb with anti-silicone grease contamination protective cover has a dynamic sealing structure formed by the second annular body at the top of the first annular body and the airbag. When the disc is installed upward, the airbag is squeezed and expands in the groove of the second annular body to form a sealing strip that fits tightly against the cavity. This can effectively block dust particles, silicone grease vapor and other impurities in the air from entering the bulb. Through the physical sealing barrier, it prevents contaminants from adhering to the surface of the LED chip, curbs the problem of accelerated light decay caused by chip contamination from the source, and significantly extends the service life of the device.

[0016] Furthermore, the second sleeve at the bottom of the cover forms a precision threaded connection with the first sleeve through the inner wall threaded groove. At the same time, it works in conjunction with the mechanical locking structure of the locking block and locking groove to build a dual stable connection system of thread pre-tightening and mechanical locking. This system not only improves assembly efficiency by utilizing the convenient disassembly and assembly characteristics of the threaded connection, but also prevents the threads from loosening through the radial limit of the locking block. This forms multiple limit protections in the axial and radial directions, ensuring that the lamp core and the cover maintain a reliable connection during long-term use. It effectively avoids the risk of loosening caused by a single connection method and significantly extends the overall service life of the bulb. Attached Figure Description

[0025] 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.

[0026] This utility model provides the following technical solution: an LED bulb with a protective cover to prevent silicone grease contamination.

[0027] Example 1: An LED bulb with an anti-silicone grease contamination protective cover, through components such as a locking block 24, a locking groove 251, and a spring 23, utilizes the interlocking cooperation between the locking block 24 and the locking groove 251 to achieve stable installation of the lamp wick 14 and the cover 15, avoiding the insufficient stability of current bulb installation structures, which easily lead to loosening and detachment after long-term use. Figure 1 - Figure 6 As shown, an LED bulb with an anti-silicone grease contamination protective cover includes a support 1. A disc 11 is provided on the top of the support 1. Side grooves are evenly formed around the disc 11. U-shaped blocks 2 are fixedly connected in the side grooves. Sliding grooves are formed on the inner wall of the disc 11. Limiting rods 21 are fixedly connected in the sliding grooves. Sliding blocks are movably connected to the limiting rods 21. Fixing blocks 22 are fixedly connected between the sliding blocks. Springs 23 are fixedly connected to the inner wall of the fixing blocks 22. A locking block is fixedly connected to the side of the fixing blocks 22 away from the springs 23. 24. A first annular body 25 is fixedly connected to the top of the disc 11. Engaging grooves 251 are evenly provided on the inner wall of the first annular body 25. Engaging blocks 24 are located in the engaging grooves 251. The disc 11 and the first annular body 25 are engaged and connected to the engaging grooves 251 through the engaging blocks 24. The sliders on both sides of the fixing block 22 are located in the sliding grooves opened on the U-shaped block 2. The fixing block 22 and the U-shaped block 2 are slidably connected through the sliders and sliding grooves. The left side of the spring 23 inside the fixing block 22 is fixedly connected to the inner wall of the U-shaped block 2.

[0028] During installation, the elastic thrust of the spring 23 drives the fixing block 22 to move axially along the limiting rod 21, so that the locking block 24 is precisely embedded in the locking groove 251 of the inner wall of the first annular body 25, realizing the mechanical locking of the disc 11 and the first annular body 25. At the same time, the sliders on both sides of the fixing block 22 slide synchronously in the groove of the U-shaped block 2. The precise cooperation between the slider and the groove forms a guide limit, effectively suppressing the radial displacement during the locking process, ensuring that the locking action is smooth and reliable, thereby providing a stable mechanical support foundation for the installation of the lamp core 14 and the cover 15.

[0029] Example 2: Unlike Example 1, by using the second annular body 3 and airbag 31, the airbag 31 is compressed while being installed by the disc 11, ensuring that the airbag 31 is fully filled within the second annular body 3. This improves the sealing effect and prevents poor sealing performance, which could allow dust, silicone grease, and other impurities in the air to easily penetrate the interior, accelerating the aging process of the LED chip and significantly shortening the bulb's lifespan. Figure 7 As shown, a second annular body 3 is fixedly connected to the top of the first annular body 25. A groove is provided at the bottom of the second annular body 3, and an airbag 31 is fixedly connected inside the groove. A mounting base 12 is fixedly connected to the top of the disc 11. A first sleeve 13 is fixedly connected to the top of the mounting base 12. A lamp wick 14 is fixedly connected inside the first sleeve 13 on the top surface of the mounting base 12. A cover 15 is provided on the top of the lamp wick 14. A second sleeve 151 is fixedly connected to the bottom of the cover 15.

[0030] During installation, when the disc 11 moves upward, it exerts axial pressure on the second annular body 3, causing the airbag 31 in the groove to expand in an annular shape and fill the cavity gap after being compressed, forming a dynamic sealing structure that is close to the contact surface. This sealing structure can effectively prevent dust particles, silicone vapor and other impurities in the air from entering the device. It prevents pollutants from adhering to the surface of the lamp core 14 through a physical barrier mechanism, thereby achieving anti-pollution protection for the light-emitting component.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] 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.
