Description

Technical Field

[0001] This utility model relates to the field of underground lighting technology, and in particular to an intelligent waterproof LED underground light. Background Technology

[0002] Traditional in-ground lights face significant risks of water immersion and immersion after installation on the ground. During use, if the top glass of an existing in-ground light is damaged by external force, water can easily enter the light body through the broken opening and come into contact with the live components inside the light body, causing a short circuit, making the in-ground light malfunction, or even causing an electric shock accident. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an intelligent waterproof LED in-ground light.

[0004] Technical Solution: A smart waterproof LED in-ground light includes a housing. A mounting ring is installed on the top of the housing by screws. A transparent glass is installed inside the mounting ring. A lamp body is installed in the middle of the housing. The lamp body includes a waterproof LED light source and its control circuit. A wiring conduit is provided at the bottom of the housing. The wiring conduit passes through the housing and is an integral structure with the lamp body. A drain valve is provided at the bottom of the housing. The housing is filled with high-pressure gas. The drain valve includes a cylinder, a drain pipe, and a movable plate. The drain pipe is fixedly connected to the middle of the cylinder. Multiple drain ports are opened at the top of the drain pipe. A movable plate is slidably connected to the drain pipe inside the cylinder. Under the pressure of the high-pressure gas, the movable plate seals all the drain ports. When the high-pressure gas leaks, the movable plate can release the seal on all the drain ports.

[0005] Furthermore, an elastic element connects the bottom of the movable plate to the bottom of the cylinder, a connecting ring is fixed to the top of the movable plate, and baffles are slidably connected inside all the drain outlets of the drain pipe, with the lower ends of all the baffles connected to the connecting ring.

[0006] Furthermore, a warning light strip is installed on the top of the mounting ring, and a pressure sensor is installed on the lamp body. Both the pressure sensor and the warning light strip are electrically connected to the control circuit of the lamp body.

[0007] Furthermore, a sealing ring is connected between the top of the housing and the bottom of the mounting ring to improve sealing performance.

[0008] Furthermore, multiple height-increasing pads are fixedly attached to the bottom of the outer shell in a ring-shaped distributed manner.

[0009] Furthermore, columnar grooves are provided on the outer surface of the casing to improve heat dissipation performance.

[0010] Beneficial effects: By setting a drain valve, this utility model can automatically release the seal of the drain outlet in the event of gas leakage caused by the breakage of the top glass inside the housing, allowing the water inside the housing to drain smoothly. This effectively prevents water from entering live components, thereby reducing the risk of short circuits and electric shocks, and significantly improving the waterproof performance and safety of the lamp.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] Please see Figures 1-5A smart waterproof LED in-ground light includes a housing 1, which serves as the main structure of the in-ground light and is made of high-strength, corrosion-resistant material to ensure the stability and durability of the light fixture during use. A mounting ring 2 is installed on the top of the housing 1 via screws 9. A transparent glass 5, made of tempered glass, is installed inside the mounting ring 2, providing good light transmission and impact resistance. A lamp body 3 is installed in the middle of the housing 1, including a waterproof LED light source and its control circuit. A wiring conduit 8 is located at the bottom of the housing 1, used to connect an external power supply to the internal circuitry of the light fixture. The structure is integrated with the lamp body 3 and extends through the housing 1. A drain valve 4 is installed at the bottom of the housing 1. The housing 1 is filled with high-pressure gas. The drain valve 4 includes a cylinder 401, a drain pipe 402, and a movable plate 404. The drain pipe 402 is fixedly connected to the middle of the cylinder 401. Three drain ports 403 are opened at the top of the drain pipe 402. The movable plate 404 is slidably connected to the drain pipe 402 inside the cylinder 401. Under the pressure of the high-pressure gas, the movable plate 404 seals all the drain ports 403. When the high-pressure gas leaks, the movable plate 404 can release the seal on all the drain ports 403.

[0019] An elastic element 405 is connected between the bottom of the movable plate 404 and the bottom of the cylinder 401. A connecting ring 406 is fixedly connected to the top of the movable plate 404. All drain ports 403 of the drain pipe 402 are slidably connected with baffles 407. The lower ends of all baffles 407 are connected to the connecting ring 406.

[0020] A warning light strip 6 is installed on the top of the mounting ring 2, and a pressure sensor 7 is installed on the lamp body 3. Both the pressure sensor 7 and the warning light strip 6 are electrically connected to the control circuit of the lamp body 3.

[0021] A sealing ring 10 is connected between the top of the housing 1 and the bottom of the mounting ring 2 to improve the sealing performance and further prevent moisture intrusion.

[0022] Multiple raising pads 11 are fixedly attached to the bottom of the outer ring. The raising pads 11 not only improve the installation stability of the lamp, but also facilitate drainage by the drain valve 4.

[0023] The outer surface of the housing 1 has columnar grooves to improve heat dissipation performance and ensure the stability of the lamp during long-term operation.

[0024] Working principle: Under normal operating conditions, the shell 1 is filled with high-pressure gas. The force exerted by the high-pressure gas on the movable plate 404 is greater than that on the elastic element 405, causing the movable plate 404 to descend inside the cylinder 401. The elastic element 405 stores elastic potential energy. The movable plate 404 drives the baffle 407 to descend synchronously through the connecting ring 406, causing the baffle 407 to seal the drain outlet 403. When the top glass inside the shell 1 is broken due to external force, causing high-pressure gas leakage, the pressure sensor 7 detects the pressure abnormality and transmits the signal to the control circuit. The control circuit controls the warning light strip 6 to light up, reminding personnel to check and deal with the lamp malfunction in time. At the same time, the internal pressure of the shell 1 decreases, causing the movable plate 404 to rise under the elastic action of the elastic element 405, and drive the baffle 407 to rise through the connecting ring 406, releasing the seal on the drain outlet 403. Thus, the water that has entered the shell 1 from the outside is discharged through the drain outlet 403 of the drain pipe 402.

[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
