[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] This application provides a light guide film with adjustable color temperature and brightness.

[0024] like Figures 1 to 5 As shown, in one embodiment of this application, the adjustable color temperature and brightness light guide film includes a light guide plate 100, a light guide base film 200, a light source 300, and an adjustment component 400.

[0025] The light guide plate 100 has an inwardly recessed storage groove 101 on its top surface. The light guide base film 200 is disposed within the storage groove 101 on the top surface of the light guide plate 100. The light source element 300 is disposed on the bottom surface of the light guide plate 100, and the light source element 300 is arranged parallel to the light guide base film 200. The adjustment element 400 is disposed on the top surface of the light guide plate 100, and the light-transmitting area of ​​the light guide base film 200 is adjusted by the adjustment element 400.

[0026] In this embodiment, light is emitted by the light source 300, and the light passes through the light guide film 200 and is emitted to the outside. The color temperature of the light guide film can be adjusted by selecting different light sources of the light source 300. The position of the adjustment member 400 relative to the light guide film 200 can also be adjusted by moving the adjustment member 400, thereby adjusting the light transmittance area of ​​the light guide film 200. By setting different light sources of the light source 300, the color temperature of the light guide film can be adjusted, and the light transmittance area of ​​the light guide film 200 can be adjusted by the adjustment member 400, thereby adjusting the brightness of the light guide film.

[0027] like Figure 5 As shown, in one embodiment of this application, the light source 300 includes a plurality of sub-light sources 301, and the plurality of sub-light sources 301 are configured as light sources with different color temperatures.

[0028] Specifically, each sub-light source 301 is driven independently by the circuit board 102, so at the same time, any one or more sub-light sources 301 can be selected to work.

[0029] In this embodiment, since each sub-light source 301 is a light source with a different color temperature, the color temperature of the light guide film can be adjusted by selecting different sub-light sources 301.

[0030] When it is necessary to lower the color temperature, simply turn off the sub-light source 301 with a higher color temperature and turn on the sub-light source 301 with a lower color temperature. When it is necessary to increase the color temperature, simply turn off the sub-light source 301 with a lower color temperature and turn on the sub-light source 301 with a higher color temperature.

[0031] like Figure 1 As shown, in one embodiment of this application, the light guide film 200 includes a light incident surface 201 and a light emitting surface 202. The plane height of the light emitting surface 202 is equal to the top surface height of the light guide plate 100, and the light incident surface 201 is arranged parallel to the light source 300.

[0032] In this embodiment, the light emitted from the sub-light source 301 enters the light guide film 200 through the light incident surface 201, and the light is refracted within the light guide film 200, thereby causing the light to exit from the light exit surface 202.

[0033] The reason for setting the height of the light-emitting surface 202 to be equal to the height of the top surface of the light guide plate 100 is to prevent the light emitted from the light-emitting surface 202 of the light guide base film 200 from being blocked by the light guide plate 100, thereby ensuring the light guiding performance of the light guide base film 200.

[0034] like Figure 2 As shown, in one embodiment of this application, multiple adjustment members 400 are provided, and all of the multiple adjustment members 400 are provided on the top surface of the light guide plate 100. Each adjustment member 400 includes a cover plate 401, a pulley 402, and a sliding frame 403. The pulley 402 is provided on the side wall of the cover plate 401, and the sliding frame 403 is fixedly connected to the top surface of the light guide plate 100. The pulley 402 is rotatably connected to the sliding frame 403 to adjust the position of the cover plate 401.

[0035] In this embodiment, multiple adjustment elements 400 adjust the light-transmitting area of ​​the light guide base film 200 from different directions, thereby improving the adjustment efficiency.

[0036] The position of the cover plate 401 relative to the light guide base film 200 is adjusted by sliding the pulley 402 within the sliding frame 403, thereby adjusting the light transmittance area of ​​the light guide base film 200.

[0037] When it is necessary to increase the light-transmitting area of ​​the light guide film 200, the cover plate 401 is moved along the sliding frame 403 towards the edge of the light guide plate 100, thereby increasing the distance between the cover plates 401 of the two adjusting members 400, thus increasing the light-transmitting area of ​​the light guide film 200.

[0038] When it is necessary to reduce the light-transmitting area of ​​the light guide film 200, the cover plate 401 is moved away from the edge of the light guide plate 100 along the sliding frame 403, thereby reducing the distance between the cover plates 401 of the two adjusting members 400, thus reducing the light-transmitting area of ​​the light guide film 200.

[0039] like Figure 3 As shown, in one embodiment of this application, the cover plate 401 includes a plurality of sub-plates 401a, which are arranged parallel to each other and abut each other end to end to form the cover plate 401.

[0040] Optionally, the cover plate 401 can also be a flexible plate, so as to ensure that the cover plate 401 can move smoothly along the sliding frame 403 while ensuring the coverage of the light guide base film 200.

[0041] In this embodiment, since the cover plate 401 is composed of multiple sub-plates 401a, when the pulley 402 slides in the sliding frame 403, it can drive each sub-plate 401a to move, thereby adjusting the overall position of the cover plate 401.

[0042] Since each sub-plate 401a is independent of each other, when the cover plate 401 is moved, the sub-plate 401a can slide along the sliding frame 403 under the drive of the roller 402b.

[0043] like Figure 3 As shown, in one embodiment of this application, the pulley 402 includes a rolling shaft 402a and a roller 402b. Each subplate 401a is provided with at least one rolling shaft 402a, and a roller 402b is rotatably connected to both ends of the rolling shaft 402a.

[0044] Optionally, the adjusting member 400 may also be equipped with a hydraulic cylinder, which is fixedly connected to the sliding frame 403. The drive rod of the hydraulic cylinder is fixedly connected to the roller 402b located at the first end, thereby driving the cover plate 401 to move through the hydraulic cylinder.

[0045] In this embodiment, the roller 402b moves along the slide groove 403c in the sliding frame 403, thereby driving the sub-plate 401a to move, thereby adjusting the relative position of the cover plate 401 and the light guide base film 200.

[0046] like Figure 3 As shown, in one embodiment of this application, the sliding frame 403 includes a horizontal portion 403a and a vertical portion 403b, which are fixedly connected to form an L-shaped structure. The horizontal portion 403a is parallel to the top surface of the light guide plate 100, and the vertical portion 403b is parallel to the side wall of the light guide plate 100. A sliding groove 403c is provided in the sliding frame 403, and the position of the cover plate 401 is adjusted by the roller 402b sliding in the sliding groove 403c.

[0047] Specifically, in order for the cover plate 401 to move smoothly from the horizontal part 403a to the vertical part 403b along the slide groove 403c, the turning point of the slide groove 403c is provided with a certain curvature.

[0048] In this embodiment, the horizontal part 403a is mainly used to move the cover plate 401, and the vertical part 403b is mainly used to store the cover plate 401. The horizontal part 403a works in conjunction with the vertical part 403b to enable the cover plate 401 to slide along the sliding frame 403.

[0049] like Figure 1 As shown, in one embodiment of this application, the light guide film with adjustable color temperature and brightness further includes a heat sink 500. The heat sink 500 includes a water pipe 501, a heat sink 503, and a circulating water pump 502. The outlet of the circulating water pump 502 is connected to the inlet of the water pipe 501. The heat sink 503 is disposed on the bottom surface of the light source 300 and is connected to the water pipe 501.

[0050] In this embodiment, since the light source 300 generates heat during operation, failure to dissipate heat in time will affect the normal operation of the light source 300.

[0051] External water is pumped into the water pipe 501 by the circulating water pump 502. The water flows through the water pipe 501 and into the heat dissipation pipe 503. Since the heat dissipation pipe 503 is in direct contact with the light source 300, the water can absorb the heat generated by the light source 300 when it flows through the heat dissipation pipe 503, thereby accelerating the heat dissipation speed of the light source 300.

[0052] like Figure 1 As shown, in one embodiment of this application, the heat dissipation pipe 503 includes a connecting part 503b and a heat-conducting part 503a. The inlet of the connecting part 503b is connected to the water pipe 501, the outlet of the connecting part 503b is connected to the inlet of the heat-conducting part 503a, and the outlet of the heat-conducting part 503a is connected to the outside.

[0053] In this embodiment, the heat dissipation unit and the water pipe 501 are connected through the connecting part 503b. The heat dissipation unit abuts against the light source 300, allowing heat from the light source 300 to be directly transferred to the heat dissipation unit and carried away by the water flow, thereby accelerating the heat dissipation speed of the light source 300. After passing through the heat dissipation unit, the water is discharged directly to the outside through the outlet of the heat dissipation unit.

[0054] like Figure 1 As shown, in one embodiment of this application, the adjustable color temperature and brightness light guide film further includes a circuit board 102, which is fixedly connected to the bottom surface of the light guide plate 100 and electrically connected to the light source 300.

[0055] In this embodiment, the light source 300 is powered by the circuit board 102, and the switching of the light source 300 is adjusted by the circuit board 102.

[0056] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
