LED chip lamps, as a new type of lighting source, have significant characteristics such as energy saving, health, environmental protection and long life.

[0003] A search revealed that patent document CN207316514U discloses a waterproof silicon carbide chip seal, comprising a housing, a mounting base, explosion-proof glass, and a sealing rubber ring. The mounting base is located at the center of the housing, and a silicon carbide chip lamp is detachably mounted on it. A PE waterproof and breathable membrane is fixedly adhered to the outer side of the mounting base using CCB reactive adhesive. A first slot is formed on the inner side of the housing opening, and the sealing rubber ring is installed inside the first slot. An aluminum heat-absorbing sheet is located on the side of the sealing rubber ring closer to the silicon carbide chip lamp, and a second slot is located on the side of the sealing rubber ring away from the first slot. The explosion-proof glass is installed inside the second slot. This invention effectively dissipates heat from inside the housing during chip use by placing an aluminum heat-absorbing sheet on one side of the sealing rubber ring and uniformly welding heat exchange tubes extending to the upper surface of the sealing rubber ring onto the aluminum heat-absorbing sheet.

[0004] The above-mentioned patent has the following shortcomings: the disassembly and assembly of silicon carbide chip lamps is inconvenient. Fixing silicon carbide chip lamps with strong adhesive may make disassembly very difficult, and may even damage the chip lamp or the mounting base. If maintenance or replacement of the chip lamp is required, the disassembly process may become complicated and time-consuming. Therefore, a waterproof silicon carbide chip sealing device is proposed to solve the problems mentioned above. Utility Model Content

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1 and Figure 2A waterproof silicon carbide chip sealing device includes a housing 3, a mounting base 2, an explosion-proof glass 1, and a sealing rubber ring 4. The mounting base 2 is located at the center of the housing 3, and a silicon carbide chip lamp 5 is detachably mounted on the mounting base 2. A PE waterproof and breathable membrane 7 is bonded to the outer surface of the silicon carbide chip lamp 5, and a sealing gasket 8 is installed between the PE waterproof and breathable membrane 7 and the mounting base 2. By setting a sealing rubber ring between the housing 3 and the explosion-proof glass 1, a sealing effect is achieved inside the housing 3.

[0026] In this embodiment, the sealing rubber ring 4 is snapped into the inside of the housing 3. An aluminum heat-absorbing sheet is provided on the side of the sealing rubber ring 4 closest to the silicon carbide chip lamp 5, and heat exchange tubes 6 are intermittently welded to the aluminum heat-absorbing sheet at equal intervals. The end of the heat exchange tube 6 away from the aluminum heat-absorbing sheet passes through the sealing rubber ring 4 and extends to its upper surface. Through the installation of the sealing gasket 8 and the PE waterproof and breathable membrane 12, in the state of water vapor, the water particles are very small. According to the principle of capillary motion, they can easily penetrate to the other side of the capillary, thus causing vapor permeation. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets, water molecules cannot easily detach from the water droplets and permeate to the other side, thus preventing water penetration and giving the PE waterproof and breathable membrane 12 a waterproof function.

[0027] Example 2:

[0028] Please see Figures 3 to 5 Based on Embodiment 1, the mounting base 2 is provided with a disassembly and assembly mechanism 9 for mounting the silicon carbide chip lamp 5. The disassembly and assembly mechanism 9 includes a disassembly and assembly base 91, a sealing collar 92, a retaining sleeve 93, a retaining block 94, a slider 96, a return spring 97, and a guide rod 98. The disassembly and assembly base 91 has an installation groove 95, a first sliding groove 99, a second sliding groove 910, and a third sliding groove 911 that communicate with the outer surface. The slider 96 is slidably disposed in the installation groove 95. The top sides of the return spring 97 and the guide rod 98 are fixed to the lower surface of the slider 96, and the bottom side of the return spring 97 is fixed to the inner bottom wall of the installation groove 95. The bottom end of the guide rod 98 penetrates the installation groove 95, and the return spring 97 surrounds the outer surface of the guide rod 98.

[0029] In this embodiment, the locking block 94 is fixedly installed inside the sleeve 93, and the sealing ring 92 is sleeved on the outer surface of the mounting / dismounting base 91, with the bottom side of the sealing ring 92 abutting against the upper surface of the slider 96, and the bottom side of the sleeve 93 abutting against the upper surface of the sealing ring 92. The first slide groove 99 and the third slide groove 911 are vertically arranged, and the second slide groove 910 is horizontally arranged, with both ends of the second slide groove 910 communicating with the first slide groove 99 and the third slide groove 911 respectively. The locking block 94 slides in cooperation with the first slide groove 99, the second slide groove 910, and the third slide groove 911.

[0030] Specifically, the silicon carbide chip lamp 5 is integrally connected to the sleeve 93, and the mounting base 91 has a through hole 912 that communicates with the outside. Except for the retaining ring 92 and the sleeve 93, the mounting mechanism 9 consists of two components. The mounting base 91 is bolted into the mounting base 2.

[0031] By adopting the above technical solution, the quick assembly and disassembly of the silicon carbide chip lamp 5 is realized. In use, the locking block 94 is extended into the first slide groove 99 and the locking sleeve 93 is moved down. The downward movement of the locking sleeve 93 drives the sealing ring 92 and squeezes the return spring 97. After the locking block 94 moves smoothly to the bottom wall of the first slide groove 99, the silicon carbide chip lamp 5 is rotated. At this time, the locking block 94 moves along the second slide groove 910 into the third slide groove 911. Finally, the pressing of the silicon carbide chip lamp 5 is released. By utilizing the deformation of the return spring 97, the locking block 94 is tightly pressed against the inner wall of the third slide groove 911, so that the silicon carbide chip lamp 5 can be quickly assembled and disassembled.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, first extend the locking block 94 into the first slide groove 99 and move the sleeve 93 down. The sleeve 93 moves down, driving the sealing ring 92 and squeezing the return spring 97. After the locking block 94 moves smoothly to the bottom wall of the first slide groove 99, rotate the silicon carbide chip lamp 5. At this time, the locking block 94 moves along the second slide groove 910 into the third slide groove 911. Finally, release the pressure on the silicon carbide chip lamp 5. Using the deformation of the return spring 97, the locking block 94 is tightly pressed against the inner wall of the third slide groove 911, so that the silicon carbide chip lamp 5 can be quickly installed and removed.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
