Description

Technical Field

[0001] This application relates to the field of lighting technology, and more particularly to a moisture-proof in-ground light. Background Technology

[0002] In-ground lights are lighting fixtures installed on the ground. They generally consist of a casing and a lamp body. By burying at least part of the lamp body below ground level, the space occupied by in-ground lights is significantly reduced, making them widely used in plazas, parks, and other similar locations. However, due to their low installation location, the light from in-ground lights shines directly into the eyes of pedestrians when they pass overhead, posing a hazard to their vision.

[0003] When in-ground lights are working, the internal structure generates heat, causing some air to expand and escape into the outside environment. When the light stops working, the internal temperature drops, creating a negative pressure environment inside the light body. At this time, outside air enters the light body through gaps. Since in-ground lights typically stop working in the early morning, and the air is more humid then, condensation will form inside the light body. This not only affects the lighting effect but can also damage the internal circuitry. Therefore, there is an urgent need for an in-ground light with better sealing and eye protection. Utility Model Content

[0004] One objective of this application is to provide a moisture-proof in-ground light that can solve at least one of the defects in the aforementioned background technology.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a moisture-proof buried light, comprising a lampshade and a lighting component, wherein the lighting component is installed inside the lampshade, a recess is provided inside the lampshade, a connecting plate is installed inside the recess, the lighting component is connected to the connecting plate, and a mutually cooperating anti-rotation mechanism is provided between the connecting plate and the recess; an installation groove is provided on the upper part of the lampshade, an annular ring is installed in the installation groove, and a light-transmitting plate is installed inside the annular ring; at least one first sealing groove is provided on the side of the annular ring, and at least one second sealing groove is provided on the lower part of the annular ring.

[0006] Through the above-described design, multiple sealing grooves work together to form a labyrinth-like seal, significantly improving the airtightness of the lampshade and preventing air from escaping due to thermal expansion, thus ensuring a constant air volume within the lampshade. When the in-ground light stops working, humid air from the outside cannot enter the lampshade, preventing the formation of water droplets inside. The anti-rotation mechanism radially limits the connecting plate to ensure the position of the lighting components remains unchanged.

[0007] Preferably, sealing rings are provided in both the first and second sealing grooves. This arrangement allows the sealing rings to fill the gap between the first and second sealing grooves, further improving the sealing effect of the in-ground light.

[0008] Preferably, the anti-rotation mechanism is a set of interlocking teeth, which are disposed on the mating surfaces of the connecting plate and the recessed portion. The inner diameter of the annular ring is smaller than the outer diameter of the connecting plate. This arrangement ensures that when the connecting plate contacts the recessed portion, the teeth on their mating surfaces engage, preventing relative rotation between the connecting plate and the lampshade. Furthermore, the annular ring, once installed, can axially limit the connection plate, ensuring that the teeth on the connecting plate and the recessed portion are always in a mating state.

[0009] Preferably, the lighting assembly includes a lamp panel, a lamp holder, and a reflector. The connecting plate is annular, with its inner ring protruding downwards to form a mounting portion. The lamp holder is fixedly connected to the mounting portion. The lamp panel is installed inside the lamp holder, and the reflector is installed above the lamp panel. This arrangement allows the reflector to reflect the light emitted by the lamp panel, thereby increasing the illumination distance and lighting area of ​​the in-ground light.

[0010] Preferably, the side wall of the lamp holder is provided with multiple heat dissipation holes. This arrangement can effectively prevent heat from concentrating in the lamp holder, and when the air inside the lamp holder is hot, it can be neutralized by the cooler air outside the lamp holder through the heat dissipation holes.

[0011] Preferably, a grille with honeycomb holes is installed above the reflector cup. This design allows the grille to reflect light, reducing glare and ensuring that the light does not irritate the eyes; the honeycomb holes further enhance the diffuse reflection effect of the grille, making the light softer and giving the in-ground light an eye-protecting effect.

[0012] Preferably, a power supply component and a limiting plate are also installed inside the lampshade. The power supply component is connected to the lamp board circuit, and the limiting plate is used to limit the position of the power supply component. This configuration allows the power supply component to supply power to the lamp board, and the limiting plate prevents the power supply component from shaking during transportation and affecting the circuit.

[0013] Preferably, the lampshade is further included as a housing, and is installed inside the housing. The lampshade has a protrusion, and the housing has a baffle that cooperates with the protrusion to support the lampshade. The protrusion and the baffle are fixedly connected by fasteners. With this configuration, the lampshade is fixedly installed inside the housing, and the housing can block the surrounding soil, preventing the lampshade from being damaged by external pressure.

[0014] Preferably, an annular pressure plate is installed on the lampshade, which is used to press the annular ring tightly against the recessed portion. This arrangement allows the sealing ring at the joint of the in-ground light to deform due to the pressing action of the annular pressure plate, further improving the sealing effect of the in-ground light.

[0015] Preferably, the outer edge of the annular pressure plate extends beyond the outer casing. This configuration allows the outer contour of the annular pressure plate to conform to the surrounding ground when the in-ground light is installed, thus preventing the in-ground light from sinking completely below the ground level.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The annular ring of this invention is provided with a first sealing groove and a second sealing groove. Multiple sealing grooves work together to form a labyrinth-like seal, significantly improving the airtightness of the lampshade and preventing air from escaping due to thermal expansion, thus ensuring a constant air volume inside the lampshade. When the underground light stops working, the internal and external air pressures remain consistent, preventing humid air from entering the lampshade and condensing into water droplets.

[0017] The anti-rotation mechanism radially limits the connecting plate to ensure the lighting component remains in place and prevents it from becoming entangled in internal wiring due to rotation. The grille on the reflector serves two purposes: it limits the reflector's position and it effectively reduces glare, resulting in a softer light from the in-ground light. This invention offers advantages such as good sealing, structural stability, and eye protection. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] One aspect of this application provides a moisture-proof in-ground light, one preferred embodiment of which is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lamp includes a lampshade 1 and an illumination component 2 installed inside the lampshade 1. A recess 11 is provided inside the lampshade 1, and a connecting plate 100 is installed within the recess 11. The illumination component 2 is fixedly connected to the connecting plate 100. An anti-rotation mechanism is provided between the connecting plate 100 and the recess 11 to radially limit the position of the connecting plate 100, ensuring that the position of the illumination component 2 remains unchanged. A mounting groove 12 is provided on the upper part of the lampshade 1, and an annular ring 3 is installed within the mounting groove 12. A light-transmitting plate 200 for protecting the illumination component 2 is provided inside the annular ring 3, and the light emitted by the illumination component 2 can be transmitted to the outside through the light-transmitting plate 200.

[0031] It should be noted that in this application, the recess 11 is located below the mounting groove 12, and the diameter of the recess 11 is smaller than the diameter of the mounting groove 12, so that all components inside the lampshade 1 can be installed in a bottom-up order.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the annular ring 3 has multiple first sealing grooves 31 on its side and multiple second sealing grooves 32 on its lower part. The multiple first sealing grooves 31 and multiple second sealing grooves 32 can cooperate to form a labyrinth-like seal, providing multiple layers of air sealing inside the lampshade 1 to prevent the air inside the lampshade 1 from escaping due to thermal expansion, thus ensuring that the amount of air inside the lampshade 1 remains constant. When the underground lamp is not in operation, humid air from the outside cannot enter the lampshade 1, thereby preventing the formation of water droplets inside the lampshade 1.

[0033] Furthermore, in order to further improve the sealing effect of the lampshade 1, sealing rings are installed in both the first sealing groove 31 and the second sealing groove 32. After the annular ring 3 is installed, the sealing ring deforms under compression and fills the gap in the first sealing groove 31 and the second sealing groove 32, which can greatly improve the sealing performance of the lampshade 1.

[0034] In this embodiment, as Figure 4 and Figure 5 As shown, the anti-rotation mechanism consists of interlocking teeth 300, which are disposed on the mating surfaces of the connecting plate 100 and the recessed portion 11. The inner diameter of the annular ring 3 is smaller than the outer diameter of the connecting plate 100. When the connecting plate 100 contacts the recessed portion 11, the teeth 300 on their mating surfaces engage with each other, preventing relative rotation between the connecting plate 100 and the lampshade 1, thus avoiding wear on the connecting plate 100 and the lampshade 1. The annular ring 3 can axially limit the connecting plate 100 to ensure that the teeth 300 on the connecting plate 100 always maintain a mating state with the teeth 300 on the recessed portion 11.

[0035] In this embodiment, as Figure 6As shown, the lighting assembly 2 includes a lamp panel 21, a lamp holder 22, and a reflector 23. The connecting plate 100 is annular, with its inner ring protruding downwards to form a mounting portion 101. The lamp holder 22 is fixedly connected to the mounting portion 101. The lamp panel 21 is installed inside the lamp holder 22, and the reflector is installed above the lamp panel 21 and coaxial with it. When the lamp panel 21 emits light, the light emitted can be reflected in the reflector 23, thereby increasing the illumination distance and illumination area of ​​the in-ground light.

[0036] Understandably, when an in-ground light is in operation for an extended period, the temperature inside the lamp holder 22 will rise rapidly. If the temperature inside the lamp holder 22 exceeds the tolerance range of the electrical components, it may cause the in-ground light to malfunction. Therefore, to further improve the service life of the in-ground light, multiple heat dissipation holes 220 connected to the lamp cover 1 are provided on the lamp holder 22. When the temperature inside the lamp holder 22 is high, it can be dissipated to the outside of the lamp holder 22 through the heat dissipation holes 220, thereby preventing the temperature inside the lamp holder 22 from exceeding the tolerance range of the electrical components.

[0037] It should be understood that, in order to achieve better illumination, the light intensity emitted by the light panel 21 is usually relatively high. Since pedestrians frequently pass above the in-ground lights, strong light may cause glare, which could harm their eyes.

[0038] In view of the above situation, in some embodiments of this application, such as Figure 6 and Figure 7 As shown, a grille 400 is installed above the reflector cup 23. The grille 400 has multiple perforations. When light enters the grille 400, the perforations reflect the light and reduce glare, ensuring that the light emitted by the in-ground light does not irritate the eyes of pedestrians. Furthermore, designing the perforations in a honeycomb pattern increases the reflective surface of the grille 400. A larger reflective surface results in a larger reflective area, which diffuses the light emitted by the light panel 21, making the light softer and providing an eye-protecting effect for the in-ground light. In addition, the grille 400 also limits the position of the reflector cup 23 to prevent it from shifting due to movement.

[0039] In this embodiment, as Figure 1 As shown, a power supply component 500 and a limiting plate 501 are also installed inside the lampshade 1. The power supply component 500 is electrically connected to the lamp board 21, and the limiting plate 501 is used to limit the position of the power supply component 500 to prevent it from colliding due to shaking. During installation, the power supply component 500 is first installed in the corresponding position inside the lampshade 1, and then the limiting plate 501 is used to lock the power supply component 500 in place. In addition, to further improve the safety of the power supply component 500, a cushioning component such as a sponge pad can be provided on the end face of the limiting plate 501.

[0040] In this embodiment, as Figure 1 As shown, it also includes a housing 4, and the lampshade 1 is installed inside the housing 4. The housing 4 can protect the lampshade 1. When the underground lamp is installed on the ground, the housing 4 can block the surrounding soil and prevent the lampshade 1 from being damaged by external pressure.

[0041] Specifically, such as Figure 2 As shown, the lampshade 1 has a protrusion 13 extending outward from its periphery, and the inner wall of the outer shell 4 is provided with a baffle 41 for supporting and limiting the lampshade 1 in conjunction with the protrusion 13. The baffle 41 and the protrusion 13 are fixedly connected by fasteners to ensure that the lampshade 1 can be stably installed on the outer shell 4.

[0042] Furthermore, such as Figure 2 As shown, an annular pressure plate 5 is installed on the lampshade 1. The annular pressure plate 5 is used to press the annular ring 3 tightly against the recessed part 11, so that the sealing ring at the joint of the buried light deforms and fills the gap, further improving the sealing effect of the buried light. In addition, the outer edge of the annular pressure plate 5 extends out of the outer shell 4. When the buried light is installed in the ground, the outer contour of the annular pressure plate 5 can fit with the surrounding ground, thereby preventing the buried light from being completely sunk below the ground level.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
