DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the following will provide a clear and complete description of the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. It is apparent that the described embodiments are only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments described in the present invention, all other embodiments derived by persons of ordinary skill in the art without requiring creative effort are within the scope of protection of the present invention.

[0023] In the following description, in order to clearly demonstrate the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0024] As attached Figure 1The diagram shows the structure of the first embodiment of the present invention. This liftable lawn light is primarily designed for landscape applications. A mounting hole 11 is provided in the lawn foundation 1 for mounting the liftable lawn light. The liftable lawn light comprises a lifting mechanism and a lamp body 3. In the unlifted state, both the lifting mechanism and the lamp body 3 are located within the mounting hole 11, and the lamp body 3 does not protrude beyond the mounting hole 11. Only upon receiving a command to lift does the lifting mechanism raise the lamp body 3 upward, and the lamp body 3 begins to emit light.

[0025] To enhance the visual experience, multiple devices can be placed in an area. When in operation, multiple lamp bodies 3 rise to emit light. They can be set to rise and fall synchronously to the same height, or to different heights, or to rise asynchronously. A variety of different variations can be used in combination to enhance the visual experience.

[0026] The lift-type lawn lights are also connected to a controller that can be integrated into wired and wireless intelligent control systems. This allows for control of the device's height, travel percentage, light on / off, brightness percentage, scenes, timing, and automation through sensors, remote controls, panels, and voice commands. Remote and local control is also possible via an app. The controller receives signals and activates the lift-type lawn lights accordingly. The controller is connected to multiple sensors, including a presence sensor and an ambient light sensor. The presence sensor detects the presence of a person, while the ambient light sensor measures the light level near the lift-type lawn lights. The controller activates the lift-type lawn lights when it detects ambient light conditions, or when someone approaches the lift-type lawn lights or a designated location. The user can customize the ambient light conditions and the specific location.

[0027] The lifting mechanism includes a lifting cylinder 2 and a lifting rod 4. The lifting cylinder 2 is fixedly arranged in the mounting hole 11, and the lifting rod 4 is sleeved in the lifting cylinder 2 to perform controllable lifting movement.

[0028] The bottom of the lamp body 3 is provided with a base 31, and the base 31 is fixedly arranged on the top of the lifting rod 4. Under the control of the controller, the lifting mechanism raises the lamp body 3 above the ground of the foundation 1 and can stop at any position within the maximum stroke.

[0029] The lamp body 3 is equipped with a lampshade to protect the internal components from damage. Because the lamp body 3 is initially located within the mounting hole 11, it could be stepped on. Therefore, the lampshade must be made of a strong, load-bearing material. Furthermore, the operating environment is outdoor, so the lampshade must be resistant to sudden changes in temperature. The lampshade can be made of a single piece of material, such as translucent resin, PC resin, or crystal glass. Alternatively, it can be made of a hollow housing made of metal, stone, or other materials, with the hollowed-out areas allowing light to pass through.

[0030] The device is used in an outdoor underground environment, so it needs to be designed with drainage function. This device can currently adopt a variety of drainage structures. For example, Figure 2 As shown, the water at the bottom of the installation hole 11 is pumped away by a water pump and transported to the drainage trough 12 next to it for drainage. Figure 3 In the structure shown, a drainage hole 44 is designed at the bottom of the installation hole 11, which is connected to the sewer to drain the accumulated water directly into the sewer. Figure 4 The structure shown is provided with a wiper disc 41 and a seal 42 in the mounting hole 11. The accumulated water is lifted upwards and discharged into the drain trough 12 from the drain port on the side wall.

[0031] In addition, a sensor is provided in the base 31 for detecting the movement of the lamp body 3. The sensor can be a distance measuring sensor for detecting the distance from the end face of the lifting cylinder below before and after each movement, thereby obtaining the distance moved by the lamp body 3.

[0032] Alternatively, other sensors can be used to detect and calculate the distance traveled by the lamp body 3. For example, a barometer can be used to detect changes in air pressure and thus determine changes in altitude. Alternatively, if a motor is used in the lifting mechanism, the number of revolutions and direction of the motor can be detected to determine how much the lamp body 3 has risen or fallen.

[0033] As attached Figure 2 The diagram shows a second embodiment of the present invention. In this device, the bottom of the mounting hole 11 is provided with a sloping bottom 13. A drainage hole 14 is provided at the lowest point of the sloping bottom 13. Drainage hole 14 is connected to a sewer. Water accumulated in the mounting hole 11 is drained from the drainage hole 14 to the sewer by gravity, thus achieving drainage.

[0034] As attached Figure 3 As shown in the schematic diagram of the third embodiment of the present invention, a water pump 5 is overhead installed in the mounting hole 11 of the device, and the water pump 5 is provided with a water suction pipe 51 and a drainage pipe 52. The end of the water suction pipe 51 is set at the lowest point of the mounting hole 11; the drainage pipe 52 is connected to the drainage trough 12; and a one-way valve 53 is provided at the end of the drainage pipe 52.

[0035] As attached Figure 4 As shown, in the fourth embodiment of the present invention, the lifting rod 4 of the device is movably sleeved with a kit 43 and drives it to move, the kit 43 is provided with a wiper disc 41, and a seal 42 is provided on the edge of the wiper disc 41, and the seal 42 fits the inner wall of the mounting hole 11; the side wall of the port of the mounting hole 11 is provided with a drain port, and the drain port is connected to the drainage groove 12; a spring is provided between the kit 43 and the lifting cylinder 2, and the spring pushes the kit 43 upward so that it is pressed against the end of the lifting rod 4; a top cover 15 is provided at the port of the mounting hole 11, and the top cover 15 is provided with a middle hole, and the size of the middle hole is larger than the lamp body 3 so that it can pass through.

[0036] A step is provided at the end of the lifting rod 4 to prevent the sleeve 43 from being separated from the lifting rod 4 .

[0037] When the lifting rod 4 is raised upwards, it can drive the wiper plate 41 to move upwards, thereby taking away the accumulated water on it and the water droplets on the inner wall of the mounting hole 11. When rising to the top, these accumulated waters can flow into the drain groove 12 from the drain port and be discharged.

[0038] The sleeve 43 is sleeved on the lifting rod 4 , and a seal is provided between the two to prevent water from leaking downward along the outer wall of the lifting rod 4 .

[0039] Furthermore, the height of the top surface of the kit 43 is higher than the height of the top surface of the wiper disc 41 . This height difference can collect a certain amount of accumulated water and prevent the accumulated water from entering the base 31 .

[0040] When the wiper plate 41 rises to the top, the lifting rod 4 can still move the lamp body 3 upward and protrude out of the mounting hole 11. Therefore, the size of the middle hole of the top cover 15 needs to be set larger than the lamp body 3 to facilitate its passage.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations within the meaning and scope of equivalents of the claims be encompassed within the present invention. Any reference numerals in the claims should not be construed as limiting the claim to which they relate.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
