Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures. The process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0023] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0024] For ease of description, the vertical direction mentioned below is the same as... Figure 1 Its vertical direction is consistent.

[0025] like Figures 1 to 4 As shown, this embodiment provides an in-ground light, including a pre-embedded cover 1 and a light source assembly 2. The pre-embedded cover 1 is used to install in a pre-embedded hole at the installation location such as the ground. The upper end of the pre-embedded cover 1 is flush with the installation location such as the ground. The light source assembly 2 can provide illumination. The light source assembly 2 is installed inside the pre-embedded cover 1 to prevent soil and other contaminants from entering the pre-embedded cover 1 and affecting the normal operation of the light source assembly 2.

[0026] The embedded cover 1 has a mounting groove 101. When the embedded cover 1 is installed in the embedded hole, the groove opening of the mounting groove 101 faces upward toward the opening of the embedded hole, so that the beam of the light source assembly 2 shines upward.

[0027] The light source assembly 2 includes a lamp holder 201, a light source body 203, a lamp cover 204, a light-transmitting element 225, and an elastic element 205. The light-transmitting element 225 includes components such as a glass plate and a lens. The lamp holder 201 is installed in the mounting groove 101, and the lamp holder 201 has a lamp groove 202. The openings of the mounting groove 101 and the lamp groove 202 are arranged facing upwards. The light source body 203 is installed in the lamp groove 202, and the lamp cover 204 is installed in the lamp holder 201.

[0028] The elastic element 205 has a connecting portion 206 installed on the lamp holder 201 and an abutting portion 207 abutting against the inner wall of the mounting groove 101. Under the action of elastic force, the abutting portion 207 of the elastic element 205 abuts against the inner wall of the mounting groove 101, using friction to fix the lamp holder 201 relative to the embedded cover 1. The lamp cover 204 has a light hole 208 communicating with the lamp groove 202. The light-transmitting element 225 is at least partially sandwiched between the lamp cover 204 and the lamp holder 201, achieving the installation and positioning of the light-transmitting element 225. The light-transmitting element 225 covers the light hole 208, and the light-transmitting element 225 and the lamp cover 204 together cover the opening of the mounting groove 101. The lamp cover 204 abuts against the upper end of the embedded cover 1, achieving a seal. The light beam from the light source body 203 shines from the opening of the lamp slot 202 and the opening of the mounting slot 101 onto the light-transmitting element 225, and finally shines from the light-transmitting element 225 onto the outside of the buried lamp.

[0029] Thus, during installation, the in-ground light of this application first installs the pre-embedded cover 1 into the pre-embedded hole in the ground, and then installs the light source assembly 2 inside the pre-embedded cover 1, using the elastic element 205 for quick positioning. When the light source assembly 2 is installed inside the pre-embedded cover 1, the lamp holder 201 of the light source assembly 2 abuts against the inner wall of the pre-embedded cover 1 through the elastic action of the elastic element 205, achieving quick installation and positioning without the need for additional screws or other connecting parts, greatly improving installation efficiency. After the light source assembly 2 is installed, the light-transmitting element 225 and the lamp cover 204 together cover the opening of the mounting groove 101, ensuring that the light from the light source body 203 can pass through while also providing a sealing effect. During disassembly and maintenance, only external force needs to be applied to overcome the elastic force of the elastic element 205 to pull the light source assembly 2 out of the pre-embedded cover 1, improving the efficiency of disassembly and maintenance. The in-ground light of this application can improve both installation and maintenance efficiency.

[0030] Optionally, the lamp holder 201 includes an inner cylinder 209 and a bottom cover 210. The lamp groove 202 is located on the inner cylinder 209. The inner cylinder 209 is cylindrical, and the lamp groove 202 extends through the inner cylinder 209 from top to bottom.

[0031] The bottom cover 210 is snapped into one end of the inner cylinder 209, and the bottom cover 210 is installed at the lower end of the inner cylinder 209 and seals the slot at the lower end of the lamp groove 202. The lamp cover 204 is snapped into the other end of the inner cylinder 209. The lamp cover 204 is provided with a hook 224, and the lower end of the inner cylinder 209 is provided with a groove 223. The engagement of the hook 224 and the groove 223 is used to achieve the snapping of the lamp cover 204 and the inner cylinder 209. The connecting part 206 of the elastic member 205 is clamped between the inner cylinder 209 and the bottom cover 210, and the abutting part 207 of the elastic member 205 extends along the direction close to the lamp cover 204. In this application, the bottom cover 210 and the lamp cover 204 are respectively installed at both ends of the inner cylinder 209 by snap-fit. The connecting part 206 of the elastic member 205 is clamped between the inner cylinder 209 and the bottom cover 210, so that the assembly of the bottom cover 210, the lamp cover 204, the inner cylinder 209 and the elastic member 205 does not require screws or other connecting parts. Compared with the existing technology that uses connecting parts for installation, it not only makes the light source assembly 2 more aesthetically pleasing, but also reduces the assembly complexity of the light source assembly 2 and improves the assembly efficiency.

[0032] Furthermore, the elastic element 205 includes a collar 211 and a plurality of elastic pieces 212 disposed on the collar 211. The plurality of elastic pieces 212 are arranged at intervals along the circumference of the inner cylinder 209.

[0033] The connecting part 206 is located on the collar 211. The elastic piece 212 extends along an arc trajectory. One end of the elastic piece 212 is connected to the collar 211, and the other end of the elastic piece 212 abuts against the lamp cover 204. The abutting part 207 is located on the outer arc surface between the two ends of the elastic piece 212, which facilitates the insertion of the light source assembly 2 into or out of the pre-embedded cover 1. The inner cylinder 209 has a limiting part 213. The collar 211 is sleeved on the inner cylinder 209 and clamped between the limiting part 213 and the bottom cover 210 to prevent the elastic element 205 from moving left or right and disengaging from the inner cylinder 209.

[0034] Optionally, the light source assembly 2 also includes a decorative strip 230. The decorative strip 230 is arranged around the inner cylinder 209. First, the collar 211 is clamped between the limiting part 213 and the decorative strip 230. After the bottom cover 210 is installed, the collar 211 and the decorative strip 230 are clamped together between the limiting part 213 and the bottom cover 210.

[0035] Furthermore, the light source assembly 2 also includes a first sealing ring 228. The bottom cover 210 is provided with a sleeve groove 214, and a sealing groove 215 is provided on the inner wall of the sleeve groove 214. The bottom cover 210 is fitted onto the inner cylinder 209 through the sleeve groove 214. The first sealing ring 228 is disposed in the sealing groove 215 and clamped between the bottom cover 210 and the inner cylinder 209, thereby achieving a seal at the bottom of the inner cylinder 209.

[0036] In one embodiment, the inground light also includes a cable 4, a locking member 5, and a sealing plug 6. The locking member 5 has a first wire hole 501, and the sealing plug 6 has a second wire hole 601. The sealing plug 6 is shaped like a platform, and the cross-section of the sealing plug 6 gradually increases along the extension path of the second wire hole 601.

[0037] The lamp holder 201 is provided with a first wiring hole 216 and a second wiring hole 217 connected in sequence. The first wiring hole 216 and the second wiring hole 217 are arranged sequentially in a direction away from the lamp groove 202, and the diameter of the first wiring hole 216 gradually increases in the direction away from the lamp groove 202, that is, the outline shape of the first wiring hole 216 matches the outline shape of the sealing plug 6. The lamp groove 202 is connected to the outside of the lamp holder 201 through the first wiring hole 216 and the second wiring hole 217.

[0038] The sealing plug 6 is fitted into the first wiring hole 216. The second wiring hole 217 is provided with internal threads. The locking member 5 is provided with external threads. The locking member 5 is located in the second wiring hole 217 and is threadedly connected to the lamp holder 201. The cable 4 extends from the outside of the lamp holder 201 through the second wire hole 601 and the first wire hole 501 to the lamp groove 202 and is electrically connected to the light source body 203.

[0039] When wiring the light source body 203 of this application, the cable 4 is first passed through the first wire hole 501 of the locking member 5 and the second wire hole 601 of the sealing plug 6. Then, the sealing plug 6 is inserted from the second wiring hole 217 into the first wiring hole 216. Next, the locking member 5 is installed in the second wiring hole 217. Finally, by rotating and tightening the locking member 5, the locking member 5 squeezes the sealing plug 6 along the direction close to the lamp groove 202. Since the diameter of the first wiring hole 216 gradually decreases along the direction close to the lamp groove 202, the sealing plug 6 is squeezed. The second wire hole 601 of the sealing plug 6 gradually decreases and tightly wraps the cable 4, achieving a better sealing effect.

[0040] Optionally, a support plate 218 is provided on the inner wall of the lamp trough 202, and the support plate 218 is integrally formed with the inner cylinder 209 of the lamp holder 201. The support plate 218 is provided with a third wire hole 219, and the light source body 203 is installed on the upper end surface of the support plate 218 to support the light source body 203. The cable 4 passes upward from the outside below the lamp holder 201 through the second wire hole 601, the first wire hole 501, and the third wire hole 219 to electrically connect with the light source body 203, so as to enable the light source body 203 to be powered.

[0041] Furthermore, the in-ground light also includes a substrate 226 and a light-cutting tube 227. The substrate 226 is mounted on a support plate 218 and electrically connected to the light source body 203. The substrate 226 is the lamp plate, and the light source body 203 is the lamp chip. The light source body 203 is mounted on the substrate 226 and electrically connected to it. The cable 4 passes through a third through-hole 219 and is electrically connected to the substrate 226. The light-cutting tube 227 is an accessory used for precise light control. It is typically mounted at the front end of the light source body 203 and shapes the shape and direction of the light through its optical structure. The light-cutting tube 227 is fitted onto the front end of the light source body 203.

[0042] In one embodiment, the light aperture 208 has a first aperture segment 220 and a second aperture segment 221 connected in sequence. The first aperture segment 220 and the second aperture segment 221 are arranged in sequence along the direction close to the lamp holder 201. The diameter of the first aperture segment 220 is smaller than the diameter of the second aperture segment 221, and an aperture shoulder 222 is formed between the first aperture segment 220 and the second aperture segment 221. The light-transmitting element 225 is convex in shape. The light-transmitting element 225 is at least partially located in the second aperture segment 221 and sandwiched between the lamp holder 201 and the aperture shoulder 222. The light-transmitting element 225 is at least partially located in the first aperture segment 220 and covers the first aperture segment 220, thereby realizing the positioning and installation of the light-transmitting element 225.

[0043] Furthermore, the light source assembly 2 also includes a second sealing ring 229. The second sealing ring 229 is sandwiched between the light-transmitting element 225 and the lamp holder 201, improving the sealing performance of the light source assembly 2 and extending its lifespan.

[0044] In one embodiment, the embedded cover 1 is cylindrical, and the outer side of the embedded cover 1 has multiple positioning planes 102. The multiple positioning planes 102 are arranged sequentially along the circumference of the light source body 203. When the embedded cover 1 is installed in a pre-embedded hole such as a square hole, the positioning planes 102 can increase the contact area between the embedded cover 1 and the inner wall of the pre-embedded hole, increase the friction, and prevent the embedded cover 1 from rotating.

[0045] Optionally, the bottom of the pre-embedded cover 1 is provided with a slot 103, and the mounting slot 101 is connected to the outside through the slot 103. When the pre-embedded cover 1 is installed in the pre-embedded hole, the slot 103 is used to achieve positioning and facilitate the wiring of the cable 4.

[0046] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
