Description

Technical Field

[0001] This utility model relates to the field of building lighting technology, specifically to a light guide tube lighting system with an impact-resistant double-layer structure. Background Technology

[0002] Light pipe lighting systems achieve indoor illumination by collecting natural light, offering energy savings and environmental friendliness. However, existing light pipe lighting systems have the following shortcomings:

[0003] Insufficient impact resistance means that single-layer skylights are easily punctured by high-speed flying stones and branches during typhoons or sandstorms, leading to water leakage and dust intrusion. This affects the normal use of the light pipes and causes irreversible damage to the entire light pipe lighting system, resulting in greater losses to the building.

[0004] Existing technologies primarily improve the impact resistance or protection of skylights through several methods. The first is to add a metal grid to the outermost layer of the skylight. However, a single-layer metal grid can only block larger branches or stones, not small pebbles or sharp objects. The second method is to increase the thickness of the skylight. However, this greatly increases production difficulty and cost, significantly reduces the light transmittance of the skylight, and cannot withstand the impact of large objects. Once damage exceeds the skylight's impact resistance, the entire skylight will lose its original function. Later replacement of major components will still not solve the problem of the light guide tube's inner wall becoming contaminated and losing its light-guiding function, requiring replacement of the light guide tube.

[0005] Therefore, there is a need for a light guide tube lighting system with enhanced protection characteristics. This system can not only maintain the integrity of its core functions under extreme conditions, but also quickly restore the system's functionality through simple maintenance and parts replacement. Utility Model Content

[0006] The purpose of this invention is to provide a light guide tube light collection system that is highly impact-resistant, has low maintenance costs, and is adaptable to extreme environments, so as to at least solve one of the problems mentioned in the background art.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A light guide tube lighting system with an impact-resistant double-layer structure is disclosed. The light guide tube lighting system includes a mounting base, a light guide tube, and a rain cap. The light guide tube passes through a hollow pre-drilled hole in the mounting base. A double-layer light-collecting cover assembly is provided on the top of the light guide tube. The rain cap is provided between the light guide tube and the double-layer light-collecting cover assembly and covers the mounting base. The double-layer light-collecting cover assembly includes an outer light-collecting cover and an inner light-collecting cover. The inner light-collecting cover is nested inside the outer light-collecting cover, and a gap is left between the inner light-collecting cover and the outer light-collecting cover.

[0009] A further improvement is that the rain cap and the light-transmitting cover assembly are fixedly connected by screws.

[0010] A further improvement is that a waterproof gasket is provided between the screw head and the outer wall of the outer light-transmitting cover.

[0011] A further improvement is that the screw passes horizontally inward through the waterproof gasket, the outer light-transmitting cover, the inner light-transmitting cover, and the rainproof cap in sequence.

[0012] A further improvement is that a sealing strip is installed between the bottom of the inner wall of the inner light-transmitting cover and the top of the outer wall of the rainproof cap, the inner wall of the sealing strip is in contact with the outer wall of the rainproof cap, and the outer wall of the sealing strip is in contact with the inner wall of the inner light-transmitting cover.

[0013] A further improvement is that the light guide tube light collection system also includes a T-shaped mounting ring, the light guide tube and the rain cap are connected by the T-shaped mounting ring, the T-shaped mounting ring is mounted on the rain cap, and the light guide tube and the T-shaped mounting ring are fixedly connected by screws.

[0014] A further improvement is that a double-walled corrugated pipe is installed on the inner wall of the hollow pre-drilled hole of the mounting base.

[0015] A further improvement is that the outer surface of the mounting base is provided with a waterproof layer.

[0016] A further improvement is that the light guide tube light collection system also includes a diffuser, which is provided at the bottom of the light guide tube.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention, by setting up a double-layer light-transmitting cover assembly, can not only effectively block direct impacts from large objects such as tree branches or stones, but also provide protection against small stones or sharp objects. Even if the outer light-transmitting cover is damaged and cracked, the inner light-transmitting cover can still provide protection. When the outer light-transmitting cover leaks slightly, the seeping water can be blocked by the inner cover, preventing dust or rainwater from entering the light guide tube and ensuring the normal use of the light guide tube.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model in a schematic manner; therefore, the drawings only show the components relevant to this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] It should be noted that when a component is said to be "mounted" on another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms “and” and “and” as used herein include any and all combinations of one or more of the associated listed items.

[0028] Please refer to the attached document. Figure 1 - Appendix Figure 3 This utility model embodiment proposes a light-collecting system with an impact-resistant double-layer structure for the light guide tube 2. The light-collecting system includes a mounting base 1, a light guide tube 2, and a rain cap 3. The light guide tube 2 passes through a hollow pre-drilled hole 4 in the mounting base 1. A double-layer light-collecting hood assembly 100 is provided on the top of the light guide tube 2. The rain cap 3 is provided between the light guide tube 2 and the double-layer light-collecting hood assembly 100. The rain cap 3 covers the mounting base 1. The double-layer light-collecting hood assembly 100 includes an outer light-collecting hood 5 and an inner light-collecting hood 6. The inner light-collecting hood 6 is nested inside the outer light-collecting hood 5, and a gap is left between the inner light-collecting hood 6 and the outer light-collecting hood 5.

[0029] Understandably, by setting up a double-layer light-transmitting cover assembly 100, this utility model can not only effectively block direct impacts from large-sized branches or stones, but also provide protection against small stones or sharp objects. Even if the outer light-transmitting cover 5 is damaged and cracked, the inner light-transmitting cover 6 can still provide protection. When the outer light-transmitting cover 5 leaks slightly, the seeping water can be blocked by the inner light-transmitting cover 6, and seep out from the gap between the inner light-transmitting cover 6 and the outer light-transmitting cover 5 through the gap between the bottom of the outer light-transmitting cover 5 and the top surface of the rain cap 3, preventing dust or rainwater from entering the light guide tube 2 and ensuring the normal use of the light guide tube 2.

[0030] After testing, when the outer skylight 5 is hit by an object and causes a slight crack, the other areas can still withstand a certain amount of impact. Therefore, in severe weather, the outer skylight 5 can withstand multiple impacts from large objects. When the outer skylight 5 leaks slightly, the infiltrated water can be blocked by the inner skylight 6.

[0031] Compared to simply increasing the thickness of the light-collecting cover, this invention uses a double-layer structure to improve impact resistance without significantly reducing the light transmittance coefficient. This ensures effective collection of natural light while enhancing the durability of the system.

[0032] Because the double-layer light-collecting dome assembly 100 provides an additional protective layer, the internal light guide tube 2 is less susceptible to the influence of the external environment, thereby reducing the cost of maintenance and replacement due to damage. Especially under extreme weather conditions, this design can greatly extend the service life of the system.

[0033] Specifically, the rain cap 3 is fixedly connected to the light-transmitting cover assembly 100 by screws 7. A waterproof gasket 8 is provided between the head of the screw 7 and the outer wall of the outer light-transmitting cover 5.

[0034] The screw 7 passes horizontally inward through the waterproof gasket 8, the outer light-transmitting cover 5, the inner light-transmitting cover 6, and the rainproof cap 3.

[0035] Understandably, the waterproof gasket 8 prevents rainwater from seeping into the system through the screw 7 holes. The use of screw 7 ensures a secure and reliable connection between the rain cap 3 and the double-layer skylight assembly 100. By horizontally passing inward through the waterproof gasket 8, outer skylight 5, inner skylight 6, and finally to the rain cap 3, a tight fit is ensured, enhancing the stability and durability of the overall structure. The screw 7 connection method allows for relatively easy disassembly of relevant components when inspection or maintenance of the system is required, without damaging other components.

[0036] In a preferred embodiment, a sealing strip 9 is installed between the bottom of the inner wall of the inner light-transmitting cover 6 and the top of the outer wall of the rainproof cap 3. The inner wall of the sealing strip 9 is in contact with the outer wall of the rainproof cap 3, and the outer wall of the sealing strip 9 is in contact with the inner wall of the inner light-transmitting cover 6.

[0037] Specifically, the sealing strip 9 is an EPDM (Ethylene Propylene Diene Monomer) sealing strip 9.

[0038] Understandably, the inner wall of the sealing strip 9 is in contact with the outer wall of the rain cap 3, while its outer wall is in contact with the inner wall of the inner light-transmitting cover 6, forming an effective sealing layer to prevent moisture or other impurities from entering the system through the gap between these two parts.

[0039] In a preferred embodiment, the light guide tube 2 light collection system further includes a T-shaped mounting ring 10. The light guide tube 2 and the rain cap 3 are connected by the T-shaped mounting ring 10. The T-shaped mounting ring 10 is mounted on the rain cap 3, and the light guide tube 2 and the T-shaped mounting ring 10 are fixedly connected by screws 7.

[0040] Understandably, by mounting the T-shaped mounting ring 10 on the rain cap 3 and then securing the light guide tube 2 to the T-shaped mounting ring 10 using screws 7, the installation becomes more convenient. Because the T-shaped mounting ring 10 provides additional support points, the connection between the light guide tube 2 and the rain cap 3 becomes more secure and reliable.

[0041] In a preferred embodiment, a double-wall corrugated pipe 11 is installed on the inner wall of the hollow pre-drilled hole 4 of the mounting base 1.

[0042] In a preferred embodiment, the outer surface of the mounting base 1 is provided with a waterproof layer. It is understood that the waterproof layer applied to the outer surface of the mounting base 1 effectively prevents rainwater or other water sources from seeping into the building interior through the mounting base 1.

[0043] In this embodiment, the light-collecting system of the light guide tube 2 further includes a diffuser 12, which is disposed at the bottom of the light guide tube 2.

[0044] Understandably, the diffuser 12 is able to uniformly scatter the concentrated light transmitted from the light guide tube 2 into the indoor space.

[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered as within the scope of this specification. The above embodiments only illustrate specific implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
