Description

Technical Field

[0001] The utility model relates to the technical field of buried lights, in particular to a moisture-proof buried light. Background Art

[0002] A buried light is a lighting facility embedded in the ground. The buried light illuminates the ground, ground vegetation, etc., making the landscape more beautiful and pedestrians safer when passing by. Currently, most buried lights use LEDs as the light source. LEDs have a long lifespan, stable performance, and save energy.

[0003] Buried lights are usually installed in ground or underground environments, which are exposed to the natural environment all year round and face various adverse weather conditions. Factors such as ground moisture, rainwater accumulation, and groundwater seepage pose threats to buried lights. A humid environment can easily cause corrosion, short circuit, or failure of the internal electronic components of the lamp, seriously affecting the service life and lighting effect. In addition, condensed water caused by temperature changes will also form inside the lamp. Therefore, buried lights must have excellent moisture-proof performance to resist the erosion of these adverse factors. Existing buried lights usually have gaps at the joints of the outer shell to facilitate the circulation and dissipation of hot air in order to improve the heat dissipation effect. However, when the environment where the buried light is located is humid, moisture will enter the inside of the buried light through these gaps, causing the internal electronic components of the buried light to get wet, thus damaging the electronic components and shortening the lifespan of the buried light.

Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be intermediate components present at the same time.

[0029] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0030] Refer to Figures 1 to 4, an embodiment of the present utility model provides a moisture-proof underground lamp, which includes a housing 10, a light-emitting component 20 and a moisture-proof system 30. The housing 10 includes an inner housing 11 and an outer housing 12. The inner cavity of the inner housing 11 is a closed cavity. The light-emitting component 20 is arranged in the inner housing 11, effectively preventing external moisture from entering the inner cavity of the inner housing 11 and initially achieving the effect of waterproofing and moisture-proofing. The moisture-proof system 30 includes a pipe 31, a U-shaped pipe 32 and a drainage mechanism 33. The pipe 31 communicates the upper end face and the lower end face of the housing 10. When the underground lamp is installed underground, the accumulated water on the ground (such as the accumulated water generated by rain) flows in from the pipe orifice of the pipe 31 located on the upper end face of the housing 10 and flows into the soil from the pipe orifice of the pipe 31 located on the lower end face of the housing 10. One end of the U-shaped pipe 32 is arranged in the pipe 31, and the other end penetrates the pipe wall of the pipe 31 and extends into the outer cavity formed by the inner housing 11 and the outer housing 12. That is, the outer cavity is communicated with the outside through the U-shaped pipe and the pipe 31. When the light-emitting component 20 in the inner cavity emits light and generates heat, the temperature of the outer cavity rises, thereby forming a hot air flow, which can not only dissipate the heat of the outer cavity to the external air, but also, if there is water vapor in the outer cavity, the water vapor is discharged from the outer cavity along with the hot air, so that the outer wall of the inner housing 11 is in a dry state; at the same time, through the setting of the U-shaped pipe, it can effectively prevent the water flowing in from the pipe orifice of the pipe 31 located on the upper end face of the housing 10 from flowing into the outer cavity. The drainage mechanism 33 is arranged on the bottom wall of the outer housing 12. When the road surface water accumulation is excessive and the water flowing into the pipe 31 submerges the U-shaped pipe and enters the outer cavity, the water in the outer cavity can be discharged through the drainage mechanism 33. The drainage mechanism 33 includes a water passing hole 331 penetrating the bottom wall of the outer housing 12 and a one-way sealing gasket 332 arranged in the water passing hole 331. The one-way sealing gasket 332 allows water to flow out of the outer cavity to the outside of the housing 10 and prevents water from flowing into the outer cavity from the outside of the housing 10 through the water passing hole 331.

[0031] Specifically, the bottom wall of the outer shell 12 is conical, and the water through-hole 331 is arranged on the axis of the bottom wall of the outer shell 12. When there is accumulated water in the outer cavity, the accumulated water will flow towards the water through-hole 331. The diameter of the water through-hole 331 changes in a stepped manner, and the diameter of the upper end of the water through-hole 331 is smaller than that of the lower end. The drainage mechanism 33 further includes a lever 333 and an inner hole 337 arranged on one side of the water through-hole 331, that is, the inner hole 337 is arranged on the bottom wall of the outer shell 12. One end of the lever 333 is located in the inner hole 337, and the other end is located in the part with a larger diameter in the water through-hole 331. A pendulum ball 334 is arranged at one end of the lever 333 located in the inner hole 337, and a support rod 335 is arranged at one end of the lever 333 located in the water through-hole 331. An installation plate 336 is arranged on the support rod 335, and a one-way sealing gasket 332 is arranged on the installation plate 336. The support rod 335 is connected to the installation plate 336 in a rolling manner. Specifically, a spherical ball 338 is arranged at one end of the support rod 335 close to the installation plate 336, and a spherical groove corresponding to the spherical ball 338 is arranged on the installation plate 336, so that the installation plate 336 can roll on the support rod 335. It should be noted that the moment at one end of the lever 333 located in the inner hole 337 is slightly greater than the moment at one end of the water through-hole 331, so that the one-way sealing gasket 332 tightly adheres to the upper end of the water through-hole 331, thereby blocking the water through-hole 331. When there is water in the outer cavity, the water is located above the one-way sealing gasket 332, making the moment at one end of the lever 333 located in the water through-hole 331 greater than the moment at one end of the inner hole 337, and the one-way sealing gasket 332 moves away from the outer cavity, so that the water through-hole 331 is unblocked; and when the water outside the water through-hole 331 flows towards the lower end face of the one-way sealing gasket 332, it cannot change the moments at both ends of the lever 333, that is, it cannot make the water through-hole 331 unblocked, so that the water cannot flow into the outer cavity from outside the housing 10.

[0032] It should be noted that the pipeline 31 can be arranged in the outer cavity or outside the outer cavity. In this embodiment, the pipeline 31 is arranged in the outer cavity.

[0033] Further, the opening of the U-shaped pipe 32 faces the upper end face of the housing 10, and the outer diameter of the parallel section of the U-shaped pipe 32 is equal to the inner diameter of the pipeline 31. A through-hole 34 corresponding to the pipeline 31 is arranged on the horizontal section of the U-shaped pipe 32. When the accumulated water on the ground flows into the pipeline 31, the water flows through the U-shaped pipe from the through-hole 34 and cannot flow into the outer cavity.

[0034] Further, an annular mounting seat 13 is arranged on the inner wall of the inner shell 11. The light-emitting component 20 includes a circuit board 21 arranged on the annular mounting seat 13, and lamp beads 22 are arranged on the circuit board 21. When the buried lamp works, the lamp beads 22 emit light to illuminate the ground, the vegetation on the ground, etc.

[0035] When the lamp beads 22 emit light, heat is also generated. To dissipate this heat outside the inner cavity, the moisture-proof buried lamp further includes a heat dissipation component 40. The heat dissipation component 40 includes a heat conduction plate 41 disposed on the lower end surface of the circuit board 21. On the side of the heat conduction plate 41 away from the circuit board 21, there is a heat dissipation fin 42, and the heat dissipation fin 42 extends into the outer cavity formed by the inner shell 11 and the outer shell 12. The heat generated by the lamp beads 22 is transferred to the outer cavity through the heat conduction plate 41 and the heat dissipation fin 42, and is dissipated into the external air through the airflow in the outer cavity.

[0036] Furthermore, an outer edge 14 is provided on the upper end surface of the inner shell 11. The outer shell 12 is fixedly connected to the inner shell 11 through the outer edge 14, and a transparent lamp cover 15 is provided on the outer edge 14.

[0037] The present utility model discloses a moisture-proof buried lamp. The specific implementation manner is as follows: When the buried lamp works, the heat generated by the light-emitting component 20 will increase the temperature of the inner shell 11. This heat can be dissipated into the external air through the air duct formed by the outer cavity surrounded by the inner shell 11 and the outer shell 12, the U-shaped tube, and the pipe 31, improving the heat dissipation effect of the buried lamp; When it rains, due to the design of the U-shaped tube, rainwater cannot enter the outer cavity through the U-shaped tube, so that the rainwater flows along the pipe 31 to the lower end surface of the housing 10 and seeps into the soil; When the water content of the soil is relatively high but there is no water accumulation on the ground, the one-way sealing gasket 332 prevents the moisture in the soil from flowing into the outer cavity through the water passing holes 331; When the rainfall is too large, causing water accumulation on the ground and the rainwater floods into the outer cavity through the U-shaped tube, the wall of the inner shell 11 can prevent the moisture from entering the cavity of the inner shell 11, and when the rainwater is drained, the rainwater in the outer cavity can be discharged into the soil through the water passing holes 331. For the moisture-proof buried lamp provided by the present utility model, its light-emitting component 20 is located in the sealed inner shell 11. The outer cavity has no water accumulation through the moisture-proof system 30, and the outer wall of the inner shell 11 is ventilated through the air duct formed by the outer cavity, the U-shaped tube, and the pipe 31, so that the outer wall of the inner shell 11 is in a dry state, thereby achieving the moisture-proof effect.

[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
