Description

Technical Field

[0001] The embodiments of this specification relate to the technical field of lighting fixtures, and in particular to a waterproof lawn lamp. Background Art

[0002] Lawn lights are outdoor lighting equipment used to improve safety and aesthetics at night. They are generally installed on the edge of roads, in courtyards, lawns and other scenes. Therefore, they are easily damaged by interference from the external environment, such as interference from weather environments such as heavy rain and fog, or interference from factors such as watering and irrigation. A better waterproof structure is required to prevent water from entering the internal circuit of the lawn lamp and causing damage. Existing waterproof lawn lights generally have waterproof covers, water guides and other structures on the outside and top of the lamp body to achieve waterproofing, or have sealing rings and other structures on the connection edges of components such as lamp beads, circuit boards, and power supplies inside the lawn lamp to achieve waterproofing. However, the internal components of lawn lamps are usually arranged in a split manner, and many sealing and waterproof structures need to be set up. In the event of extreme heavy rain, it is impossible to avoid water entering the bottom of the lawn lamp, which causes the water level inside the lawn lamp to rise and cause circuit damage.

[0025] The following is a detailed description of a waterproof lawn lamp according to an embodiment of the present specification in conjunction with the accompanying drawings. Figure 1 , Figure 2 As shown, a waterproof lawn lamp according to an embodiment of the present specification includes a ground plug 1, a lamp tube 2, and a light source assembly located inside the light-transmitting portion 22 of the lamp tube 2, wherein the light source assembly includes a light-emitting module 31 and a power supply module 32 at the bottom of the light-emitting module 31, wherein the power supply module 32 is sleeved with a waterproof shell, and the light source assembly is clamped inside the lamp tube 2 through the waterproof shell. The lawn lamp is fixed to the road surface through the ground plug 1, and at this time, the light-transmitting portion 22 is usually located at the top of the lawn lamp, and the light source assembly that needs to transmit light through the light-transmitting portion 22 is also located in the upper part of the lawn lamp. Therefore, the existing waterproof structure of the lawn lamp mainly targets the problem of water seepage from above the lawn, etc. When encountering extreme rainstorm weather, the water level rises rapidly, which can easily cause rainwater to seep into the lawn lamp from bottom to top, and damage the internal circuit of the lawn lamp from below. The light emitting module 31 and the power supply module 32 of the embodiment of the present specification are integrated into a light source assembly, and the power supply module 32 at the bottom is covered with the waterproof shell, which blocks the light source assembly and the space below the lawn lamp. Even if the water level rises due to leakage under the lawn lamp, the waterproof shell and the space pressure below the waterproof shell prevent the water level from rising to a certain level and causing damage to the light source module.

[0026] The waterproof shell includes a recessed portion 41 and an extension portion 42 located around the upper surface of the recessed portion 41. The outer edge of the extension portion 42 is stuck above the protrusion 21 provided on the inner wall of the lamp tube 2. The power supply module 32 is located in the recessed portion 41, and the edge of the light emitting module 31 is sealed and connected with the inner edge of the extension portion 42. The extension portion 42 is stuck above the protrusion 21. When the water level below the lawn lamp rises while the waterproof shell is fixed, it is first stopped by the protrusion 21. The side of the protrusion 21 is in close contact with the outer side of the recessed portion 41, and the side of the extension portion 42 is in close contact with the inner wall of the lamp tube 2. The two contact surfaces are not in the same plane, which effectively prevents water seepage from bottom to top. The light emitting module 31 is an LED lamp or other form of lamp with a lamp shell. The edge of the lamp shell is sealed and connected with the inner edge of the extension portion 42. A sealing ring and a sealing strip can be added to enhance the sealing effect to prevent water seepage from above the light source assembly.

[0027] The inner wall of the lamp tube 2 above the protrusion 21 is provided with an internal thread, and the side of the extension 42 is provided with a thread for matching the internal thread. The inner wall of the lamp tube 2 and the extension 42 are threadedly connected, which not only enhances the stability of the waterproof shell, but also increases the contact area and tightness of the extension 42 with the inner wall of the lamp tube 2, further preventing water seepage. Figure 4 As shown, the contact area between the extension portion 42 and the inner wall of the lamp tube 2 is increased. The height of the outer edge 421 of the extension portion 42 can also be increased so that the height of the outer edge 421 of the extension portion 42 is higher than the inner edge 422. A smooth curved surface is recessed downward between the outer edge 421 and the inner edge 422 of the extension portion 42 to minimize the influence on the light transmission of the light-emitting module 31.

[0028] In addition, if Figure 2 As shown, in one embodiment, a waterproof layer 211 is provided on the inner wall of the lamp tube 2 under the protrusion 21, which is in close contact with the outer surface of the recessed portion 41. The waterproof layer 211 fills the space between the outer surface of the recessed portion 41 and the inner wall of the lamp tube 21, thereby increasing the sealing performance between the recessed portion 41 and the inner wall of the lamp tube 2. In this embodiment, the edge of the light emitting module 31 is flush with the plane where the outer surface of the extension portion 42 is located, so that a rubber ring, a waterproof strip, etc. can be provided in the gap between the light emitting module 31 and the extension portion 41, and the rubber ring, the waterproof strip, etc. are not easy to fall off after installation, thereby ensuring waterproof sealing performance.

[0029] In another embodiment, Figure 3As shown, the lower surface of the protrusion 21 is provided with an elastic abutting plate 212 that abuts against the outer surface of the recessed portion 41. The elasticity of the elastic abutting plate 212 makes the connection between the elastic abutting plate 212 and the recessed portion 41 tighter and less prone to water seepage. The surface of the elastic abutting plate 212 in contact with the recessed portion 41 is provided with an adhesive layer, which is waterproof, further increasing the tightness of the connection between the elastic abutting plate 212 and the recessed portion 41 and the connection stability of the waterproof shell. Compared with the previous embodiment, the edge of the light-emitting module 31 in this embodiment is raised, and the moisture that penetrates into the surface of the extension portion 42 is not easy to affect the light-emitting module 31.

[0030] When the edge of the light emitting module 31 is raised, if the inner edge 422 of the extension portion 42 is lower than the edge of the light emitting module 31, moisture can easily penetrate into the recessed portion 41 from the gap between the inner edge 422 and the edge of the light emitting module 31, affecting the power supply module 32 inside the recessed portion 41. Figure 4 As shown, the inner edge 422 of the extension portion 42 is higher than the middle position between the outer edge 421 and the inner edge 422, and the inner edge 422 is not lower than the edge of the light-emitting module 31. On the one hand, the moisture that penetrates into the surface of the extension portion 42 preferentially flows to the lower middle position of the extension portion 42, thereby avoiding the influence of water seepage on the light-emitting module 31 to a certain extent. On the other hand, the height of the inner edge 422 is relatively high, and the gap between the inner edge 422 and the edge of the light-emitting module 31 is also raised, so that it is not easy for moisture to enter the recessed portion 41 through the gap to affect the power supply module 32.

[0031] The lamp tube 2 is provided with a water outlet channel 231 on the inner wall of the outer edge 421 of the extension portion 42 . The outlet height of the water outlet channel 231 is lower than the inlet height. When the lamp tube 2 is accidentally flooded, the infiltrated water can flow out from the water outlet channel 231 .

[0032] The lamp tube 2 includes a light-transmitting portion 22 and a lamp body 23. The light-transmitting portion 22 is sleeved on the outer wall of the lamp body 23, and the waterproof shell is clamped on the inner wall of the lamp body 23. The sleeve connection method facilitates installation and removal of the light-transmitting portion 22, the lamp body 23, and the light source assembly inside. The light-transmitting portion 22 is sleeved on the outer wall of the lamp body 23, which facilitates installation and removal and is not easy to get wet.
