[0028] See also Figure 1 The inverter device 1000 in the embodiment of the present invention may include the light guide panel structure 100 in the embodiment of the present invention. The inverter device 1000 also includes an inverter panel structure 200 and a PCB board 300. The light guide panel structure 100 is specifically connected to the PCB board 300, and the inverter panel structure 200 is arranged in a laminated manner with the light guide panel structure 100. The light guide panel structure 100 is fixed to the inverter panel structure 200 to display the inverter status.

[0029] The light guide panel structure 100 is described in detail below. Figure 2 、 Figure 3 and Figure 4 As shown, the light guide panel structure 100 includes a light guide panel body 10 and a silicone sleeve 112. The light guide panel body 10 is provided with a light-transmitting surface 11, on which a plurality of first light guide pillars 111 are disposed. The spacing between adjacent first light guide pillars 111 is 3 mm to 20 mm. The silicone sleeve 112 is fitted over the first light guide pillars 111 to encapsulate them.

[0030] Specifically, the light guide panel body 10 is the main portion of the light guide panel structure 100. The light guide panel body 10 has a light-transmitting surface 11 through which light is transmitted. A plurality of first light guide pillars 111 are disposed within the light-transmitting surface 11. These first light guide pillars 111 serve as light sources for the light guide panel structure 100 and transmit light through the light-transmitting surface 11. The first light guide pillars 111 guide light to the LED chips, allowing them to transmit light. Each first light guide pillar and the light guide panel structure 100 are integrally formed.

[0031] The spacing between two adjacent first light guides 111 is 3 mm to 20 mm, that is, the first light guides 111 are densely arranged and arranged throughout the light-transmitting surface 11. The light-transmitting surface 11 is specifically a frosted light-transmitting surface 11. After the frosted light-transmitting surface 11, the light projected from the light-transmitting surface 11 can be softer and more uniform.

[0032] In the prior art, when light sources (light guides) in an inverter are closely arranged, the light emitted by each light guide can interfere with the light emitted by other light guides, affecting the optical performance of the emitted light. To prevent the light from interfering with each other, prior art typically disperses the light guides in the inverter panel. However, in this case, light must propagate through the angled light guides, undergoing multiple total reflections within the angled light guides before reaching the transmission surface, resulting in significant light intensity loss.

[0033] Therefore, in the present invention, in order to avoid the light emitted by each closely arranged light guide column from interfering with each other. The present invention is provided with a silicone sleeve 112 on each closely arranged first light guide column 111, and one silicone sleeve 112 is correspondingly sleeved on one first light guide column 111, and the silicone sleeve 112 is sleeved on the outer periphery of the first light guide column 111 to wrap the first light guide column 111. Because the first light guide column 111 is cylindrical, the silicone sleeve 112 is also cylindrical. The inner diameter of the silicone sleeve 112 is slightly larger than the outer diameter of the first light guide column 111, so that the first light guide column 111 can be set into the silicone sleeve 112. And because of the friction between the inner wall of the silicone sleeve 112 and the outer wall of the first light guide column 111, the silicone sleeve 112 will not loosen from the first light guide column 111.

[0034] Therefore, by placing the silicone sleeve 112 over the first light guide pillars 111, even if the first light guide pillars 111 are closely arranged, when each first light guide pillar 111 is guiding light, the light directed in the surrounding area will be absorbed by the silicone sleeve 112, and the light emitted by each first light guide pillar 111 will be concentrated and emitted from the first light transmission hole, thereby not affecting the light emitted by the first light guide pillar 111. This can effectively reduce the mutual interference between the light beams emitted by the first light guide pillars 111 in the light guide panel structure 100, thereby improving the output efficiency of the light guide panel structure 100 and reducing crosstalk or confusion in the light emitted by the light guide panel structure 100.

[0035] Furthermore, the light guide panel structure 100 with the silicone sleeve 112 is separated from the PCB 300. During assembly, the silicone sleeve 112 may be squeezed by the PCB 300 due to tolerances, but the flexible deformation of the silicone sleeve 112 can offset this tolerance. This design allows for a certain degree of flexibility between the light guide panel structure 100 and the PCB 300, reducing assembly issues caused by inconsistent tolerances. The flexibility of the silicone sleeve 112 not only protects the light guide panel structure 100 from excessive pressure but also ensures that the first light guide column 111 maintains good optical performance during actual use.

[0036] Furthermore, in a possible embodiment, the silicone sleeve 112 is a black silicone sleeve 112. Specifically, setting the silicone sleeve 112 as a black silicone sleeve 112 can further improve the light absorption ability of the silicone sleeve 112, thereby further reducing the effect of the light emitted by each first light guide column 111 affecting each other.

[0037] Furthermore, in a possible implementation manner, as Figure 2 、 Figure 3 and Figure 4 As shown, for each silicone sleeve 112 , one end of the silicone sleeve 112 abuts against the surface of the light guide panel body 10 , and the other end of the silicone sleeve 112 extends out of the first light guide column 111 .

[0038] Specifically, one end of the silicone sleeve 112 abuts a surface of the light guide panel body 10 opposite the light-transmitting surface 11. The other end of the silicone sleeve 112 extends beyond the first light guide pillar 111 by 2 to 3 mm. Furthermore, the other end of the silicone sleeve 112 abuts against the PCB board 300, forming a bond with the PCB board 300. Therefore, by having the other end of the silicone sleeve 112 extend beyond the first light guide pillar 111, the first light guide pillars 111 can be completely enclosed within the silicone sleeve 112, ensuring that each first light guide pillar 111 does not affect the light-guiding effect of other first light guide pillars.

[0039] Furthermore, in addition to the first light guide pillar 111 , in a possible implementation manner, a plurality of second light guide pillars 113 are further disposed on the light-transmitting surface 11 , and the second light guide pillars 113 are disposed at intervals.

[0040] Specifically, in addition to the first light guide column 111, the light guide panel structure 100 is also provided with a second light guide column 113. Moreover, each second light guide column 113 is arranged at intervals in a rectangular shape. In the present invention, the distance between two adjacent second light guide columns 113 is relatively far, so for each second light guide column 113, the light emitted by each other will not affect each other, so there is no need to set a silicone sleeve 112 on each second light guide column 113. Therefore, the distance between two adjacent first light guide columns 111 is smaller than the distance between two adjacent second light guide columns. That is, the distance between two adjacent second light guide columns 113 is greater than 20 mm. Similarly, each second light guide column 113 and the light guide panel structure 100 are also specifically integrally formed.

[0041] In the present invention, the arrangement of the second light guide pillars 113 can increase the flexibility of the light emitted by the light guide panel structure 100 .

[0042] Furthermore, in a possible implementation, the light guide panel structure 100 further includes a sealing strip 12 , which is disposed on the periphery of the light-transmitting surface 11 and is used to seal the light-transmitting surface 11 on the light guide panel body 10 .

[0043] Specifically, the light guide panel structure 100 further includes 12 sealing strips, which can seal the light-transmitting surface 11 to the light guide panel body 10. In particular, when the inverter panel structure 200 is placed in contact with the light guide panel structure 100, the 12 sealing strips can be squeezed to form a sealing effect on the inverter panel structure 200.

[0044] Furthermore, in one possible embodiment, the light guide panel structure 100 further includes a first surface 13 disposed opposite the light-transmitting surface 11, and reinforcement ribs 131 are disposed on the first surface 13. Specifically, to increase the strength of the light guide panel structure 100, the reinforcement ribs 131 are disposed on the first surface 13 of the light guide panel structure 100. The provision of the reinforcement ribs 131 can enhance the strength of the light guide panel structure 100, distributing the forces applied to the light guide panel structure 100 and reducing the risk of deformation and damage to the light guide panel structure 100, thereby enhancing the overall stability and durability of the light guide panel structure 100.

[0045] Furthermore, in one possible embodiment, the light guide panel structure 100 further includes a plurality of fixing grooves 114, which are spaced apart from the light-transmitting surface 11. The fixing grooves 114 are disposed on the periphery of the light-transmitting surface 11. Specifically, the light guide panel structure 100 further includes a plurality of fixing grooves 114, which are located on the same surface of the light guide panel structure 100 as the light-transmitting surface 11. The provision of the fixing grooves 114 allows screws to be driven into the fixing grooves 114 to securely connect the inverter panel structure 200 to the light guide panel structure 100.
