Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a light guide tube light-collecting device. Background Technology

[0002] Natural lighting is crucial for improving indoor lighting and energy conservation. Light pipe lighting technology is economical, energy-efficient, and improves lighting quality. It has been successfully applied in building interiors, underground spaces, and hazardous areas with excellent results. The principle of light pipe lighting technology is that a light-collecting dome gathers natural light, which is then redistributed by the system, transmitted through the light pipe, and then evenly illuminated by a diffuser, providing sufficient light even during the day. With technological advancements, this system is widely used in practical engineering projects, bringing natural light to areas that are difficult to reach using traditional methods. Compared to traditional skylights, it does not affect building structural safety, consumes no energy, and improves indoor environmental quality, making it energy-saving, environmentally friendly, and healthy. However, existing light pipe lighting systems have defects in waterproofing and connection structure design, resulting in structural instability and susceptibility to water seepage at the joints between components and walls. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a light guide tube lighting device is provided to solve the problem of water seepage at the junction of existing light guide tube lighting systems and walls.

[0004] To achieve the above objectives, a light guide tube light-collecting device is provided, comprising:

[0005] A cylindrical pier is cast onto a roof panel. The pier has a vertical through hole inside. The lower end of the vertical through hole penetrates the roof panel. The waterproof membrane of the roof panel is turned up along the side wall of the pier and covers the top of the pier.

[0006] A light guide tube is inserted into the vertical through hole. The upper end of the light guide tube has a flange arranged around the circumference of the light guide tube. A weather-resistant heat insulation ring is fitted onto the upper end of the light guide tube. The upper opening of the weather-resistant heat insulation ring extends to form an extension that fits against the lower surface of the flange.

[0007] A diffuser is installed at the lower port of the light guide tube;

[0008] A light-transmitting cover is provided over the upper port, and the opening of the light-transmitting cover extends to the outside of the weather-resistant heat-insulating ring;

[0009] The guide tube includes an upper tube section, a lower tube section, and a reducing tube section. The upper tube section is sleeved on the outside of the weather-resistant heat insulation ring. The upper end of the upper tube section presses against a layer away from the flange of the extension. The upper port of the light guide tube is equipped with a cover for locking the light-collecting dome and a first locking member for locking the upper tube section. The lower tube section is sleeved on the upper end of the pier. The reducing tube section covers the upper end of the pier and is connected to the upper tube section and the lower tube section. The upper end of the pier is equipped with a second locking member for locking the lower tube section.

[0010] A sealing ring is placed between the inner wall of the opening of the light-transmitting cover and the outer wall of the upper pipe section.

[0011] Furthermore, the sealing ring has a first side facing the upper pipe section and a second side facing away from the upper pipe section, and the thickness of the sealing ring gradually increases from the first side to the second side.

[0012] Furthermore, the outer wall of the upper pipe section is formed with a receiving groove, the receiving groove is arranged in a circle along the circumference of the upper pipe section, and a limiting part is formed on the first side of the sealing ring, the limiting part being embedded in the receiving groove.

[0013] Furthermore, a sealing strip is formed on the inner wall of the reducing pipe section, and the sealing strip presses against the top of the pier.

[0014] The beneficial effects of this utility model are as follows: the light guide tube light-collecting device of this utility model mainly consists of a light-collecting dome set on a concrete pier, a light guide tube connected below the light-collecting dome and extending into the pier, and a diffuser set below the light guide tube. A guide tube is set between the light-collecting dome and the cast-in-place concrete pier. The guide tube and the light guide tube are connected by a weather-resistant heat-insulating ring. The light guide tube and the weather-resistant heat-insulating ring are connected by screws. The bottom of the light-collecting dome is covered on the upper section of the guide tube. A waterproof layer (i.e., formed by the upward turning of the waterproof membrane of the roof) is set around the pier. The guide tube is covered on the waterproof layer. A diffuser is set at the bottom to enhance light transmittance and diffusion.

[0015] This utility model's light guide tube lighting device improves upon the shortcomings of existing light guide tube lighting systems in terms of waterproofing and connection structure, possessing excellent waterproof and dustproof properties. A guide pipe is installed between the light-collecting dome and the light guide tube, connected by a weather-resistant heat-insulating ring and reinforced with screws to ensure a stable and waterproof connection. On rainy days, rainwater flows along the light-collecting dome to the guide pipe, and then to the outer waterproof layer of the pier base, preventing water accumulation and seepage. A waterproof membrane is also installed between the inner wall of the pier base and the light guide tube, which not only prevents water seepage into the wall but also supports the light guide tube.
