Description

Technical Field

[0001] This utility model belongs to the field of light guide plate technology, specifically relating to a light guide plate system adapted to multiple light sources. Background Technology

[0002] With the widespread application of modern optical technology, the demand for high-quality, diversified light source distribution continues to rise, from display devices and lighting systems to medical equipment and scientific instruments. As a key component for achieving uniform and efficient light source output, the performance and adaptability of light guide plates have become a focus of attention in many fields. Traditional light guide plate systems are gradually revealing numerous problems in meeting the increasingly complex optical application scenarios. In the display field, with the rapid development of technology, various display devices such as liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs) are constantly evolving towards higher resolution, larger sizes, and thinner designs. This presents a significant challenge to the backlight design behind the display panel.

[0003] Traditional single-structure light guide plates struggle to adapt to various types, quantities, and layouts of light sources, leading to uneven light distribution, bright and dark spots, and edge light leakage, severely impacting display quality and user experience. For example, in large-screen LCD TVs, multiple light sources need to work together to ensure consistent brightness across the screen, but traditional light guide plates cannot flexibly adjust to these differences, significantly degrading image quality. In commercial lighting, different product display areas require varying intensities and angles of light to highlight product features, but traditional light guide plates struggle to achieve this precise light control.

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a multi-light source adapted light guide plate system, including,

[0027] The support assembly 100 includes a fixed plate 101, a support rod 102 hinged to the side wall of the fixed plate 101, a crossbeam 103 inserted into the side wall of the support rod 102, and a support plate 104 fixedly connected to the side wall of the crossbeam 103.

[0028] The light guide plate assembly 200 includes a main plate body 201 inserted into the middle of the support plate 104, a baffle 202 fixedly connected to the side wall of the main plate body 201, and a secondary plate body 203 movably inserted into the side wall of the main plate body 201, with the end of the secondary plate body 203 extending to the outside of the support plate 104.

[0029] The fixing plate 101, as the basic fixing component of the entire support assembly, serves for connection and positioning. It is typically installed on the required work platform or equipment to ensure the stability of the entire system. The support rod 102 is hinged to the side wall of the fixing plate 101. This hinged design allows the support rod 102 to adjust the angle of the fixing plate 101. This allows for flexible changes in the overall posture of the support assembly to meet the support requirements of the light guide plate assembly in different environments. Simultaneously, the side wall of the support rod 102 has a sliding groove structure, providing a track for the installation and movement of the crossbeam 103. The end of the crossbeam 103 is slidably inserted into the middle of the sliding groove on the side wall of the support rod 102. This sliding connection allows the crossbeam 103 to be adjusted in position along the direction of the sliding groove on the support rod 102. The support plate 104 is fixedly connected to the side wall of the crossbeam 103 to support the light guide plate assembly 200, providing a stable plane for the installation of the light guide plate. Its position and angle can be adjusted by adjusting the support rod 102 and the crossbeam 103 to achieve precise positioning of the light guide plate assembly. The main board 201, inserted into the middle of the support plate 104, is the core component of the light guide plate assembly, primarily responsible for light transmission. Made of special optical materials, it possesses excellent light transmission and guiding properties, enabling the input light to be evenly distributed across the entire board. The baffle 202 is fixedly connected to the side wall of the main board 201, serving to block and constrain light, preventing leakage from the side of the main board 201 and improving light utilization efficiency. Simultaneously, the baffle 202 provides a track for the installation and sliding of the sub-board 203. The side wall of the sub-board 203 slides into the inside of the baffle 202, allowing the sub-board 203 to be positioned on the main board 201 according to actual needs.

[0030] Specifically, the side wall of the sub-plate 203 is slidably inserted into the inner side of the retaining edge 202, and the side wall of the sub-plate 203 is provided with a side strip structure.

[0031] The sub-plate 203 features a side strip structure on its sidewall, increasing friction with the retaining edge 202 and ensuring stable positioning after adjustment. The sub-plate 203 is movably inserted into the sidewall of the main plate 201, with its end extending to the outside of the support plate 104. The sub-plate 203 can be flexibly adjusted according to the position and number of different light sources, working in conjunction with the main plate 201 to further optimize light distribution and transmission.

[0032] Furthermore, the light guide plate assembly 200 also includes a mounting plate 204 fixedly connected to the end of the sub-plate body 203. The mounting plate 204 extends to the side wall of the support plate 104. The mounting plate 204 is located outside the edge 202, and the side wall of the mounting plate 204 is provided with mounting holes.

[0033] A mounting plate 204 is fixedly connected to the end of the sub-plate 203. The mounting plate 204 extends to the side wall of the support plate 104 and is located outside the edge 202. The side wall of the mounting plate 204 has mounting holes, through which external light source devices can be easily installed on the sub-plate 203 to achieve the adaptation connection between multiple light sources and the light guide plate.

[0034] Preferably, the side wall of the support rod 102 is provided with a groove structure, and the end of the crossbeam 103 is slidably inserted into the middle of the groove on the side wall of the support rod 102. The support assembly 100 also includes a first handle bolt 105 threadedly connected to the end of the crossbeam 103, and the end of the first handle bolt 105 is engaged with the outside of the support rod 102.

[0035] When it is necessary to fix the position of the crossbeam 103, tighten the first handle bolt 105, and its end will be engaged with the outside of the support rod 102, thereby firmly locking the crossbeam 103 in the required position and ensuring that it will not be displaced during use.

[0036] Preferably, the support assembly 100 further includes a second handle bolt 106 inserted into the side wall of the fixing plate 101, and the end of the second handle bolt 106 is threaded to the side wall of the support rod 102.

[0037] The angle of the support rod 102 can be further fine-tuned by rotating the second handle bolt 106, thereby improving the accuracy and convenience of adjustment.

[0038] When using this multi-light source compatible light guide plate system, first adjust the position and angle of the light guide plate assembly 200 by adjusting the support assembly 100 according to the actual usage scenario and requirements. Specifically, loosen the first handle bolt 105, slide the crossbeam 103 on the groove of the support rod 102 as needed, adjust it to a suitable position, and then tighten the first handle bolt 105 to fix it. At the same time, the angle of the support rod 102 can be finely adjusted by rotating the second handle bolt 106 to achieve the ideal support posture.

[0039] When installing the light source equipment, the equipment is mounted on the sub-plate 203 through the mounting holes on the mounting plate 204, according to the number and location requirements of the light sources. If it is necessary to adjust the position of the sub-plate 203 to better accommodate the light sources, the sub-plate 203 can be slid directly inside the baffle 202, and its position can be fixed by the friction between the edge strip structure of the side wall of the sub-plate 203 and the baffle 202.

[0040] When the light source is turned on, light enters the main board 201 and the secondary board 203. The main board 201, with its excellent light-guiding properties, initially conducts and diffuses the light within the board. The side guard 202 effectively prevents light leakage from the sides, concentrating the light more on the front light-emitting area of ​​the light guide plate. The secondary board 203, based on its relative position to the main board 201 and the distribution of the light source, further distributes and supplements the light transmission, ensuring that the entire light guide plate system can output light uniformly and efficiently, meeting the requirements for light distribution and intensity in different scenarios.

[0041] In summary, the adjustable design of the support component 100, including the angle adjustment of the support rod 102 and the position adjustment of the crossbeam 103, as well as the flexible sliding of the sub-plate 203 in the light guide plate assembly 200, enables the system to adapt to different installation environments and multi-light source layout requirements. Whether in spaces with limited space or in situations requiring complex light source distribution, optimal light guiding effects can be achieved by adjusting the positions of each component. The collaborative work of the main plate 201 and the sub-plate 203, along with the effective constraint of light by the edge 202, significantly improves light utilization efficiency. It can evenly distribute light from multiple light sources across the entire surface of the light guide plate, reducing light loss and unevenness, and providing stable, high-quality light source output for subsequent optical applications. The mounting plate 204 and its mounting holes in the light guide plate assembly 200 facilitate the installation and fixation of external light source equipment. Construction personnel can quickly and accurately install light source equipment on the sub-plate 203, reducing installation time and difficulty and improving work efficiency.
