Description

Technical Field

[0001] This utility model relates to the field of lighting engineering technology, and more specifically, to a small light-collecting tracking lighting system device. Background Technology

[0002] While existing fiber optic indoor lighting technology has gradually entered home environments, a key challenge remains in practical applications. The coupling efficiency between the focused sunlight spot and the fiber optic end face is typically only about 75%, resulting in significant energy loss during coupling and poor overall lighting efficiency. The fundamental reason is that, limited by the physical structure of the optical lens, it is difficult to achieve a perfect diameter match between the focused light spot and the fiber optic end face, allowing only a small amount of light to penetrate and propagate within the fiber. Therefore, we propose a small-scale light-collecting tracking lighting system. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a small light-collecting tracking lighting system device to solve the technical problem of low coupling efficiency of current fiber optic indoor lighting equipment.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a small light-gathering tracking lighting system device, comprising a light-gathering structure for converging natural light to form a focused light spot, a transmission structure for transmitting the light energy output by the light-gathering structure, and a dual-axis tracking drive structure for connecting the light-gathering structure and the transmission structure. The dual-axis tracking drive structure includes a horizontal and vertical transmission motor housing, which integrates a horizontal rotation motor and a pitch motor. The light-gathering structure includes a large plano-convex optical light-collecting lens. The transmission structure includes a light-splitting integral light-receiving end. The light-gathering structure also includes an intelligent light sensor, which is fixed on a semi-circular bracket provided on the outside of the large plano-convex optical light-collecting lens.

[0005] Preferably, the diameter of the focused light spot formed by the focal area of ​​the large plano-convex optical light-collecting lens is smaller than the light-collecting diameter of the optical fiber light-collecting surface provided at the top of the light-collecting end of the light-fusing integral light-collecting end.

[0006] Preferably, the transmission structure further includes a circular metal ring fiber optic fixing bracket and a bundle-locking fiber optic cable. The bundle-locking fiber optic cable is located on the side away from the light receiving surface at the bottom of the light-fusing overall light receiving end, and a bundle of several optical fibers is connected to the bottom. The circular metal ring fiber optic fixing bracket is connected to the optical fiber receiving surface, and the optical fiber receiving surface is fixed in the focal area of ​​the large plano-convex optical light-collecting lens based on the circular metal ring fiber optic fixing bracket.

[0007] Preferably, the light-collecting structure is rigidly connected to the output end of the horizontal and vertical transmission motor box based on a semi-circular bracket. The output end of the horizontal rotary motor rotates around the vertical axis to adjust the azimuth angle of the semi-circular bracket, and the output end of the pitch motor drives the light-collecting structure and the transmission structure to pitch around the horizontal axis to adjust the elevation angle.

[0008] Preferably, the bottom of the dual-axis tracking drive structure is provided with several fiber optic integral L-shaped fixing brackets, and the side of the fiber optic integral L-shaped fixing brackets away from the dual-axis tracking drive structure is installed on the concrete surface.

[0009] Preferably, the large plano-convex optical light-collecting lens is fixed on the circular ring of the semi-circular bracket, and the optical fiber receiving surface is composed of a quartz rod formed by integrating the incident end faces of multiple optical fibers through a melting process.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the coordinated design of a light-gathering structure, a transmission structure, and a dual-axis tracking drive structure, not only utilizes a large plano-convex optical lens to efficiently gather natural light into a focused spot, but also uses an intelligent light sensor fixed on its outer semi-circular bracket to accurately detect the sun's position in real time and transmit signals. In conjunction with the horizontal rotation motor and pitch motor integrated in the horizontal and vertical drive motor box, the light-gathering structure and transmission structure are driven to work together to achieve precise tracking of the sun's altitude and azimuth angles, ensuring that the light-gathering structure is always in the optimal light-gathering posture. At the same time, relying on the light-emitting fuse integrated light receiving end, it efficiently receives and transmits focused light energy, effectively solving the problems of inaccurate light gathering and high light energy transmission loss in traditional devices, and solving the technical problem of low coupling efficiency in current fiber optic indoor lighting equipment.

[0012] 2. This utility model further limits the diameter of the focused light spot in the focal area of ​​the large plano-convex optical light-collecting lens to be smaller than the light-collecting diameter of the optical fiber receiving surface at the top of the light-splitting overall light-receiving end. With the help of a circular metal ring optical fiber fixing bracket, the optical fiber receiving surface is precisely fixed in the focal area of ​​the lens. This ensures that the focused light spot completely covers the receiving surface and there is no light energy leakage, which greatly reduces coupling loss. The light-collecting structure is rigidly connected to the output end of the horizontal and vertical drive motor box through a semi-circular bracket. By using a horizontal rotating motor to adjust the azimuth angle and a pitch motor to drive the light-collecting and transmission structure to adjust the elevation angle around the horizontal axis, it can achieve precise tracking of the sun's position and keep the lens in the best light-collecting posture. The three work together to further improve the light energy utilization and light-collecting accuracy, and ensure the stability of the structural linkage, making the energy transmission of the lighting system more efficient and the use more reliable.

Detailed Implementation

[0016] like Figures 1 to 2 As shown, this utility model relates to a small light-gathering tracking lighting system device, which includes a light-gathering structure for converging natural light to form a focused light spot, a transmission structure for transmitting the light energy output by the light-gathering structure, and a dual-axis tracking drive structure for connecting the light-gathering structure and the transmission structure. The dual-axis tracking drive structure includes a horizontal and vertical transmission motor housing 800, which integrates a horizontal rotation motor and a pitch motor. The light-gathering structure includes a large plano-convex optical light-collecting lens 100. The transmission structure includes a light-fusing integrated light-receiving end 300. The light-gathering structure also includes an intelligent light sensor 500, which is fixed on a semi-circular bracket 400 provided on the outside of the large plano-convex optical light-collecting lens 100.

[0017] This invention utilizes a synergistic design of a light-gathering structure, a transmission structure, and a dual-axis tracking drive structure. It efficiently converges natural light into a focused spot using a large plano-convex optical lens 100, while a smart light sensor 500 fixed to its outer semi-circular bracket 400 accurately detects the sun's position in real time and transmits signals. Combined with a horizontal rotation motor and a pitch motor integrated within the horizontal and vertical drive motor housing 800, this drives the light-gathering and transmission structures in a coordinated manner, achieving precise tracking of the sun's altitude and azimuth angles. This ensures the light-gathering structure is always in the optimal light-gathering posture. Simultaneously, the light-fusing integrated light-receiving end 300 efficiently receives and transmits the focused light energy, effectively solving the problems of inaccurate light gathering and high light energy transmission loss in traditional devices, and addressing the low coupling efficiency of current fiber optic indoor lighting equipment.

[0018] Specifically, the diameter of the focused light spot formed by the focal area of ​​the large plano-convex optical light-collecting lens 100 is smaller than the light-collecting diameter of the optical fiber receiving surface at the top of the optical fiber receiving end 300 of the optical fiber fusion cut-off integral light-collecting end. By limiting the diameter of the focused light spot in the focal area of ​​the large plano-convex optical light-collecting lens 100 to be smaller than the light-collecting diameter of the optical fiber receiving surface at the top of the optical fiber receiving end 300 of the optical fiber fusion cut-off integral light-collecting end, it can be ensured that all the focused light spots gathered by the lens are completely covered by the optical fiber receiving surface, avoiding light energy overflow loss caused by the edge of the light spot exceeding the light-collecting range. From the perspective of size matching, the optical energy coupling efficiency is maximized, laying the foundation for subsequent high-efficiency transmission.

[0019] Furthermore, the transmission structure also includes a circular metal ring fiber optic fixing bracket 700 and a bundle-splitting fiber optic locker 600. The bundle-splitting fiber optic locker 600 is located on the side away from the light receiving surface at the bottom of the light-framing integrated receiver 300, and a fiber bundle 900 composed of several optical fibers is connected to its bottom. The circular metal ring fiber optic fixing bracket 700 is connected to the optical fiber receiving surface, and the optical fiber receiving surface is fixed to the focal area of ​​the large plano-convex optical light-collecting lens 100 based on the circular metal ring fiber optic fixing bracket 700. In the transmission structure, the circular metal ring fiber optic fixing bracket 700 can accurately fix the optical fiber receiving surface to the focal area of ​​the large plano-convex optical light-collecting lens 100, ensuring the relative position stability of the receiving surface and the light spot, and avoiding coupling deviation caused by vibration or displacement. The bundle-splitting fiber optic locker 600 manages the receiving end face of the fiber bundle 900 at the bottom of the light-framing integrated receiver 300, preventing the fiber end face from being messy and tangled, which would affect the transmission stability. The two work together to improve the accuracy of optical energy transmission and the reliability of the structure.

[0020] It is worth noting that the light-gathering structure is rigidly connected to the output end of the semi-circular bracket 400 and the horizontal and vertical drive motor housing 800. The output end of the horizontal rotary motor rotates around the vertical axis to adjust the azimuth angle of the semi-circular bracket 400, and the output end of the pitch motor drives the light-gathering structure and the transmission structure to pitch around the horizontal axis to adjust the elevation angle. The rigid connection between the light-gathering structure and the output end of the horizontal and vertical drive motor housing 800 through the semi-circular bracket 400 ensures the synchronization of the light-gathering and transmission structures during tracking. The horizontal rotary motor specifically adjusts the azimuth angle and pitch angle. The pitch motor drives the entire system to adjust the elevation angle around the horizontal axis, achieving precise and independent control of changes in the solar azimuth and elevation angles. This avoids the tracking lag problem of single-axis drive, ensuring that the large plano-convex optical light-collecting lens 100 is always in the optimal light-gathering posture, thus improving the light-gathering efficiency throughout the entire sky. The horizontal and vertical drive motor box 800, in conjunction with the intelligent light sensor 500, achieves electrical control. The intelligent light sensor 500 mainly drives and adjusts the drive components within the horizontal and vertical drive motor box 800, which is existing technology and will not be described in detail.

[0021] This invention further limits the diameter of the focused light spot in the focal area of ​​the large plano-convex optical light-collecting lens 100 to be smaller than the light-collecting diameter of the optical fiber receiving surface at the top of the light-fusing overall light-receiving end 300. Combined with the circular metal ring optical fiber fixing bracket 700, the optical fiber receiving surface is precisely fixed in the focal area of ​​the lens, ensuring that the focused light spot completely covers the receiving surface without any light energy leakage, significantly reducing coupling loss. The light-collecting structure is rigidly connected to the output end of the horizontal and vertical drive motor box 800 via a semi-circular bracket 400. By adjusting the azimuth angle with a horizontal rotating motor and the elevation angle by driving the light-collecting and transmission structure to tilt around the horizontal axis with a pitch motor, precise tracking of the sun's position can be achieved, ensuring the lens always maintains the optimal light-collecting posture. The synergy of these three elements further improves light energy utilization and light-collecting accuracy, while also ensuring the stability of the structural linkage, making the energy transmission of the lighting system more efficient and its use more reliable.

[0022] It is worth mentioning that the bottom of the dual-axis tracking drive structure is equipped with several fiber optic integrated L-shaped fixing brackets 200. The side of the fiber optic integrated L-shaped fixing brackets 200 away from the dual-axis tracking drive structure is installed on the concrete surface. The several fiber optic integrated L-shaped fixing brackets 200 at the bottom of the dual-axis tracking drive structure can firmly install the entire device on the concrete surface. By distributing the weight of the device through multi-point support, it effectively resists the shaking or displacement caused by external interference such as wind, ensuring the relative position stability of the dual-axis tracking drive structure, the light collection structure and the transmission structure, and providing a solid installation foundation for accurate tracking and efficient coupling.

[0023] It is worth noting that the large plano-convex optical light-collecting lens 100 is fixed on the circular ring of the semi-circular bracket 400. The optical fiber receiving surface is composed of a quartz rod made of the incident end faces of multiple optical fibers integrated by a fusion process. The large plano-convex optical light-collecting lens 100 is fixed on the circular ring of the semi-circular bracket 400, which not only ensures the firmness of the lens installation, but also ensures that the optical axis of the lens is aligned with the center of the optical fiber receiving surface through the concentric design of the circular ring, reducing optical deviation. The optical fiber receiving surface is made of a quartz rod made of the incident end faces of multiple optical fibers integrated by a fusion process, which greatly expands the effective light-collecting area compared with a single optical fiber end face. At the same time, the fusion process ensures the integrity and flatness of the receiving surface, further reducing light energy coupling loss and improving light collection efficiency.

[0024] Working Principle: This embodiment provides a small-scale light-gathering tracking lighting system. In use, several fiber optic L-shaped fixing brackets 200 at the bottom of the dual-axis tracking drive structure are installed on a concrete surface. During operation, the intelligent light sensor 500 detects the azimuth and elevation angles of the sun in real time and transmits the detection signals to the electrical control module inside the horizontal and vertical drive motor box 800 of the dual-axis tracking drive structure. The semi-circular bracket 400 rotates around the vertical axis of the horizontal and vertical drive motor box 800 to adjust the azimuth angle of the device. The pitch motor drives the light-gathering structure and the transmission structure to pitch around the horizontal axis, synchronously adjusting the elevation angle. In the light-gathering stage, the large plano-convex optical light-collecting lens 100 focuses natural light onto its focal area to form a focused light spot. The coupled light energy is conducted to the bottom through the light-emitting fusion splice light receiving end 300, and then transmitted to the target lighting area through the fiber optic bundle 900 managed by the fiber optic cable lock-locker 600, ultimately realizing the utilization and illumination of natural light.
