Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a modular, quick-installation waterproof underground light. Background Technology
[0002] As core equipment for landscape lighting and road marking, in-ground lights directly impact project efficiency and long-term maintenance costs due to their ease of installation, waterproof reliability, and style flexibility. Traditional in-ground lights typically employ an integrated encapsulation design, which, while meeting basic lighting needs, suffers from high costs associated with style replacement in practical use. The rigid encapsulation of the lamp body and light source module necessitates a complete replacement and reassembly of the lamp body for style changes, which is time-consuming and labor-intensive. Furthermore, this assembly method results in less robust waterproofing, leading to poor waterproofing performance. Therefore, there is an urgent need for a modular, quick-install waterproof in-ground light that, while ensuring sufficient waterproofing performance of the light source module, allows for rapid replacement of different lamp shades and light source modules through hot-swapping, thereby saving costs.

The light source module 1 includes a light-transmitting top cover 11 and an in-ground sleeve 12. The in-ground sleeve 12 is nested around the periphery of the light-transmitting top cover 11. The disassembly and assembly mechanism 3 includes a lug 31, a mating groove 32, a bayonet 33, and a hook 34. The lug 31 and the mating groove 32 are located between the light-transmitting top cover 11 and the lampshade 2. The lug 31 can be fitted into the mating groove 32 to restrict the lampshade. 2. Relative to the axial rotation of the light-transmitting top cover 11, the latch 33 and the hook 34 are provided between the lug 31 and the mating groove 32. The hook 34 can be held in the latch 33 to restrict the lug 31 from disengaging from the mating groove 32, thereby restricting the lampshade 2 from disengaging from the light-transmitting top cover 11. The lower side of the light-transmitting top cover 11 is provided with a component mounting port 111. The waterproof mechanism 4 includes a sealing cover 41 embedded in and sealing the component mounting port 111. An adhesive potting area 42 is formed between the inner wall of the component mounting port 111 and the sealing cover 41. This utility model discloses an in-ground light, comprising a light source module 1 and a lampshade 2, and further including a disassembly and assembly mechanism 3 and a waterproof mechanism 4. The light source module 1 includes a light-transmitting top cover 11 and an in-ground sleeve 12. The in-ground sleeve 12 is pre-installed in a pre-drilled hole in the ground. The light-transmitting top cover 11 serves to transmit light and enclose electronic components. The disassembly and assembly mechanism 3 includes a lug 31, a mating groove 32, a latch 33, and a hook 34. Regardless of changes in the lampshade's style, the lamp can be disassembled simply by engaging the lug 31 with the mating groove 32 and engaging the latch 33 with the hook 34. With the cooperation of hook 34, different styles of lampshades 2 can be quickly installed and removed from the light-transmitting top cover 11; at the same time, the waterproof mechanism 4 includes a sealing cover 41. After the electronic components are placed in the internal space of the light-transmitting top cover 11, the sealing cover 41 seals the component mounting port 111. Furthermore, a potting area 42 for filling with sealing gel is formed between the inner wall of the component mounting port 111 and the sealing cover 41, so that the lamp can achieve modular replacement of lampshades while also having sufficient waterproof performance and being more durable.
[0024] The lugs 31 are arranged axially around the upper side of the light-transmitting top cover 11, and the mating grooves 32 are arranged axially around the lower side of the lampshade 2.
