Description

Technical Field

[0001] The utility model relates to the technical field of building light pipes, in particular to a high-efficiency light-collecting introduction device in a building interior. Background Art

[0002] In architectural design, light pipe technology is widely used to guide sunlight into buildings to maximize natural light and reduce energy consumption. However, traditional light pipe systems face many technical challenges in practical applications, especially in terms of light guiding efficiency and light transmission distance.

[0003] First, while high-quality light pipes can achieve a light transmission efficiency of around 90%-98%, and even approach the upper limit under ideal conditions over short transmission distances, this efficiency gradually decreases with increasing length and bending of the pipe. When a light pipe's length exceeds 25 times its diameter, the light entering the room becomes extremely weak, making it unsuitable for long-distance transmission.

[0004] Secondly, the entrance design of traditional light pipes often fails to effectively capture and utilize sunlight at oblique angles. Due to the changing position of the sun, especially during non-noon hours, the incident sunlight is not perpendicular. As a result, the area of ​​sunlight collected at the entrance of the light pipe is much smaller than the opening area, thus limiting the light collection efficiency. Utility Model Content

[0005] The purpose of the utility model is to address the problems existing in the prior art and provide a high-efficiency light-collecting introduction device for indoor use in buildings. Through the secondary focusing design of concentrating heliostats and concentrating reflectors, sunlight is effectively collected and efficiently introduced into a light guide, solving the problem of reduced light intensity caused by the increase in length and bending of traditional light guides.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A high-efficiency light-collecting device for indoor use in a building comprises a concentrating heliostat device and a concentrating reflector device.

[0009] The universal joint assembly includes a threaded rod, a ball head seat and a fastening bolt.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] Traditional light pipe entrance designs often fail to effectively capture and utilize oblique sunlight. Due to the varying position of the sun, especially during non-noon hours, the incident light is not perpendicular. Consequently, the area of ​​sunlight collected at the entrance of the light pipe is much smaller than the opening area, limiting light collection efficiency.

[0032] Traditional light pipe systems also face challenges with light focusing and temperature control. In strong sunlight, failure to effectively focus and transmit light can not only cause the temperature inside the light pipe to rise, but can also damage the light pipe material, reducing system safety and stability.

[0033] Regarding the above technical issues, such as Figures 1 to 6As shown, the present application provides a high-efficiency light-collecting device for indoor use in a building, comprising a concentrating heliostat device and a concentrating reflector device. The concentrating heliostat device comprises a planar support 1 and an adjustment support connected to the planar support 1. The planar support 1 is provided with a plurality of planar mirrors 2, each of which is connected to the planar support 1 via a universal joint assembly. Together, the planar mirrors 2 constitute a heliostat. The adjustment support is used to adjust the pitch angle and horizontal angle of the planar support 1. The concentrating reflector device comprises a housing 3, one end of which is connected to an insulating glass 4 and the other end is connected to a light inlet of a light pipe 5. A reflector 6 is fixedly provided inside the housing 3. The concentrating heliostat device is used to concentrate sunlight for incident light on the insulating glass 4. The reflector 6 is used to receive light from the insulating glass 4 and reflect it to the light inlet of the light pipe 5. The light outlet of the light pipe 5 is provided inside the building.

[0034] The light-collecting device achieves efficient sunlight collection and transmission through the synergistic effect of a concentrating heliostat assembly and a concentrating reflector assembly. The concentrating heliostat assembly consists of a planar support 1 and an adjustment bracket. Planar support 1 is equipped with multiple planar mirrors 2 connected by a universal joint assembly, which can be adjusted to the optimal angle for sunlight collection. The adjustment bracket is used to adjust the pitch and horizontal orientation of planar support 1 to ensure precise sunlight collection. The collected sunlight enters the concentrating reflector assembly through insulating glass 4. It is received and reflected by a reflector 6 fixed within the housing 3 to the light inlet of a light guide 5. Finally, the light outlet of the light guide 5 is introduced into the room, providing natural light for the interior.

[0035] To maximize the capture of sunlight, heliostats are typically installed facing due south, particularly at noon when the sun is at its highest point and the sunlight is most intense and stable. Concentrating reflectors are installed facing due north, directly opposite the heliostats, to receive and refocus the light reflected from the heliostats.

[0036] This embodiment of the present invention utilizes a secondary focusing design using concentrating heliostats and concentrating reflectors to allow more sunlight to enter a smaller diameter light pipe, overcoming the problem of reduced light intensity caused by the length and bending of traditional light pipes. Furthermore, the use of insulating glass effectively filters infrared rays, reducing the temperature rise caused by sunlight in the room or on the light pipe, thereby improving the safety and stability of the system. Compared to traditional light pipes, this embodiment of the present invention provides a more effective lighting effect and is suitable for long-distance, high-efficiency sunlight introduction into building interiors.

[0037] Plane mirrors are easy to manufacture at low cost. When all the mirrors are parallel, the light spot of the entire heliostat is a large light spot. By adjusting the angle of each mirror, the small light spots are moved to overlap at the center of the large light spot. By fixing all the mirrors, the heliostat can stabilize a small high-magnification sunlight spot throughout the day.

[0038] A planar support 1 is equipped with multiple plane mirrors 2 connected by universal joints. Each plane mirror 2 can be independently adjusted, so the focus point of the entire heliostat can be flexibly changed. This allows the focus position of light to be adjusted according to actual needs, enhancing applicability.

[0039] It's important to note that if a light pipe has a light transmittance of 98%, even if it receives 50 times the sunlight, it will only generate the same amount of heat on the light pipe wall as 1 times the sunlight. This is because most of the light is effectively transmitted into the building, while only a very small amount is absorbed by the light pipe wall and converted into heat. Therefore, by precisely controlling the area of ​​the heliostats and the diameter of the light pipe, the amount of light entering the light pipe can be further adjusted, effectively controlling the temperature inside the light pipe. Furthermore, designing the light pipe with a heat dissipation structure, such as adding heat sinks or using thermally conductive materials, can also effectively dissipate heat.

[0040] In some embodiments, the adjustment bracket includes a vertically arranged rod body 7, which is connected to the adjustment mechanism; the adjustment mechanism includes a shell 8, in which a horizontal angle drive motor 9 is fixedly provided, and the output shaft of the horizontal angle drive motor 9 is connected to the upper end of the rod body 7 through a first gear set; a pitch angle drive motor 10 is fixedly provided in the shell 8, and the output shaft of the pitch angle drive motor 10 is connected to a horizontal rotating rod 11 through a second gear set, and both ends of the horizontal rotating rod 11 extend out of the shell 8 and are fixed to the back of the planar bracket 1 through several connecting seats 12.

[0041] The horizontal angle drive motor 9 is connected to the upper end of the rod body 7 via a first gear set. A small gear is connected to the motor output shaft, and a large gear is fixedly mounted on the upper end of the rod body 7, meshing with the large gear. Since the rod body 7 is fixed to the ground, when the motor is started, the small gear rotates relative to the large gear, thereby driving the adjustment mechanism to rotate horizontally relative to the rod body 7, thereby adjusting the horizontal angle of the planar support 1. Simultaneously, the pitch angle drive motor 10 is connected to the horizontal rotating rod 11 via a second gear set. Both ends of the horizontal rotating rod 11 extend out of the housing 8 and are fixed to the back of the planar support 1 via several connecting seats 12, thereby driving the planar support 1 to tilt in the pitch direction, achieving precise adjustment of its angle. Through the coordinated action of the horizontal angle drive motor 9 and the pitch angle drive motor 10, the heliostat can adjust its angle in real time to ensure that it is always aligned with the sun, thereby improving the efficiency of solar energy collection.

[0042] In some embodiments, the universal joint assembly includes a threaded rod 13, a ball head seat 14 and a fastening bolt 15. One end of the threaded rod 13 is connected to the threaded hole on the back of the plane mirror 2, and the other end is connected to the ball head 16. The ball head seat 14 is fixed to the plane bracket 1 by bolts, and the ball head 16 is movably inserted into the ball head seat 14; the fastening bolt 15 passes through the threaded hole of the plane bracket 1 and abuts against the ball head 16 for fastening the ball head 16.

[0043] Ball mount 14 is bolted to support bracket 1, forming a stable support point. Ball head 16 snaps into ball mount 14, enabling flexible adjustment of mirror 2 in multiple directions to meet the needs of use in varying lighting conditions. To fix the angle of mirror 2, simply tighten bolt 15 through the threaded hole in support bracket 1 and into contact with ball head 16, locking it into ball mount 14. This ensures that mirror 2 will not shift due to vibration or external forces during long-term use, improving reliability and durability.

[0044] In some embodiments, a plurality of plane mirrors 2 are distributed in two rectangular arrays on a plane support 1. This layout optimizes space utilization and ensures that each set of plane mirrors can receive sufficient sunlight, thereby maximizing solar energy collection efficiency in a specific time period or geographical location.

[0045] In some embodiments, the reflector 6 is a parabolic mirror, and the focus of the reflector 6 is located at the lower side of the light inlet of the light pipe 5 .

[0046] The focus of the reflector 6 is precisely positioned below the light inlet of the light guide 5. When sunlight strikes the parabolic mirror, it is focused and reflected to the focal point. Because the relative position between the reflector 6 and the light guide 5 is fixed, the focal point remains fixed as long as the heliostat is operating normally. Even if the heliostat malfunctions and stops operating, the heliostat's light spot will not reach the concentrating reflector above, and there will be no sunlight focus below. This eliminates the risk of sunlight focus shifting to the light guide wall and burning the light guide.

[0047] like Figure 7 As shown, further, the reflector 6 is a portion where a parabola and a cylindrical surface overlap, and the diameter of the cylindrical surface is slightly larger than the light spot and can collect all the sunlight of the light spot.

[0048] In some embodiments, the light pipe 5 is provided with a plurality of light outlets, each of which is independently provided indoors. By providing multiple light outlets, each light outlet is equivalent to an independent light source, which can provide natural light to each building interior, thereby improving the utilization efficiency of solar energy.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
