[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0038] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] like Figures 1-2 As shown, a screen lighting module 100 provided by this utility model includes a light source module 110, a polarizing element 120, a fixing device 130, and a screen component 150.

[0040] like Figure 3 and Figure 5As shown, the light source module 110 includes a light source substrate 1101 and a light-emitting component 1102 disposed on the light source substrate 1101. The light-emitting component 1102 is composed of at least two different colored light-emitting elements (such as LED beads) arranged alternately and linearly. By matching the power of the different colored light-emitting elements, an ultra-wide color gamut of 1800K-12000K can be achieved, providing colorful decorative lighting effects for indoor use and meeting the decorative needs of different scenarios.

[0041] like Figure 3 and Figure 5 As shown, the polarizing element 120 is located on the light-emitting side of the light source module 110. In the optical axis direction of the polarizing element 120, both the inner and outer surfaces of the polarizing element 120 are smooth free-form surfaces. The inner surface has a receiving portion 1201 that is recessed towards the outer surface. The light-emitting component 1102 is housed in the receiving portion 1201, making the fit between the light-emitting component 1102 and the polarizing element 120 tighter, thus ensuring the stability and effectiveness of light during transmission.

[0042] In this embodiment, the polarizing element 120 is a polarizing lens. In other embodiments, the polarizing element 120 may also be a reflector, or a combination of a polarizing lens and a reflector, etc., and there is no limitation here.

[0043] The polarizing element 120 is made of transparent PC material through extrusion molding. It can achieve no yellow-blue separation phenomenon without the need to add diffusion materials or surface treatment, and has high luminous efficiency and uniform light output.

[0044] The polarizing element 120 can deflect the light emitted by the light source module 110, achieving a uniform distribution of light on the light receiving surface 1505 of the screen component 150. Furthermore, due to its smooth inner and outer surfaces, no further surface treatment is required, preventing yellow-blue separation. This allows for more precise deflection and control of the light, resulting in a uniformly distributed illumination effect on the light receiving surface 1505 of the screen component 150, significantly improving light efficiency.

[0045] like Figure 3 and Figure 5 As shown, the fixing device 130 is connected to the polarizing element 120 and limits the light source module 110 between the polarizing element 120 and the fixing device 130. The fixing device 130 has a power supply cable (not shown) passing through a cable channel 1301 electrically connected to the light source module 110 on the side facing away from the light source module 110. The fixing device 130 ensures the relative position stability of the light source module 110 and the polarizing element 120, while facilitating the connection of the power cable, making the entire screen lighting module 100 structure more compact and stable.

[0046] like Figures 4-5As shown, connector 140 connects polarizing element 120 and fixing device 130, and has a first connecting hole 1401 and a second connecting hole 1402 for power cord to pass through. The first connecting hole 1401 communicates with light source module 110, and the second connecting hole 1402 communicates with wiring channel 1301. Connector 140 not only makes the connection between fixing device 130 and polarizing element 120 tighter and safer, but also facilitates the connection and routing of power cord between various components, making the electrical connection of the entire screen lighting module 100 more organized, safe, and convenient for installation and maintenance.

[0047] During the assembly of a screen lighting module 100, a connector 140 is used to connect the polarizing element 120 and the fixing device 130, and the power cord is passed through the first connection hole 1401 and the second connection hole 1402 in sequence to finally realize the electrical connection of the screen lighting module 100.

[0048] like Figure 2 and Figure 6 As shown, the screen component 150 includes a first wall 1501 and a second wall 1502 spaced apart from each other, and a connecting wall 1503 connecting the first wall 1501 and the second wall 1502. The screen component 150 is also provided with a mounting groove 1504 for mounting and fixing device 130 and a light receiving surface 1505 extending arcuately from the mounting groove 1504. That is, the light receiving surface 1505 is arcuately arranged and located on the light output path of polarizing element 120.

[0049] Specifically, the mounting slot 1504 is located at one end of the screen component 150, and the light receiving surface 1505 extends from one side wall of the mounting slot 1504 in a direction away from the mounting slot 1504. The light source module 110, the polarizing element 120, and the fixing device 130 are all housed in the mounting slot 1504. The mounting slot 1504 provides installation space for the fixing device 130, ensuring the assembly stability of the entire screen lighting module 100. The arc-shaped light receiving surface 1505 can better receive the light after it has been deflected by the polarizing element 120, improving the light receiving efficiency.

[0050] The mounting slot 1504 is defined by a first wall 1501, a second wall 1502, and a connecting wall 1503. A light-receiving surface 1505 is disposed on the first wall 1501. The projection of the second wall 1502 onto the light-receiving surface 1505 covers the projections of the light source module 110 and the polarizing element 120 onto the light-receiving surface 1505, effectively shielding the light source module 110 and the polarizing element 120, preventing direct light from hitting the eyes, reducing glare, and improving comfort and safety during use. In this embodiment, the first wall 1501 is generally arc-shaped; however, in other embodiments, the first wall 1501 can also be flat, as long as the light-receiving surface 1505 is arc-shaped to receive light refracted by the polarizing element 120, thereby improving light reception efficiency.

[0051] The connecting wall 1503 is arc-shaped, and the side of the fixing device 130 facing away from the polarizing element 120 abuts against the connecting wall 1503. The arc-shaped connecting wall 1503 not only makes the screen component 150 more aesthetically pleasing, but also allows it to better cooperate with the fixing device 130, enhancing the stability of the entire structure.

[0052] The light-receiving surface 1505 is a white surface that has been sandblasted or frosted, which can further scatter light, making the light more uniform and soft. At the same time, the white surface can also better reflect light, enhancing the lighting effect.

[0053] Furthermore, at least two screen lighting modules can be spliced ​​together to form a luminous screen. Of course, multiple sets can also be spliced ​​together according to actual needs, and the splicing length can be adjusted arbitrarily to adapt to different scene requirements.

[0054] The following will illustrate the assembly steps of a screen lighting module 100 and a luminous screen, but should not be considered as a whole:

[0055] (1) Fabrication of light source module 110: Select a light source substrate 1101 with a length of 40cm, and arrange red, green and blue LED beads alternately on the light source substrate 1101, with 20 beads of each color. By adjusting the power of different colored LED beads, multiple color changes can be achieved.

[0056] (2) Fabrication of polarizing element 120: Using transparent PC plastic, a polarizing element 120 with smooth inner and outer surfaces is fabricated by extrusion process. The size (width and height) is approximately 8.3mm × 2.6mm, and the length is customized to 40cm according to the length of the light source module 110.

[0057] (3) Assemble the fixing device 130 and the connector 140: Make the fixing device 130 and provide a wire passage 1301 on the fixing device 130. At the same time, make the connector 140 and provide a first connecting hole 1401 and a second connecting hole 1402 on the connector 140.

[0058] (4) Install screen component 150: Make screen component 150. Fix the fixing device 130 and the polarizing element 120 through the connector 140, so that the light source module 110 is limited between the polarizing element 120 and the fixing device 130, and then install it as a whole into the mounting groove 1504 of the screen component 150, so that the side of the fixing device 130 away from the polarizing element 120 abuts against the connecting wall 1503.

[0059] (5) Connect the power cord: Pass the power cord through the first connection hole 1401 and the second connection hole 1402 of the connector 140 in sequence, and finally connect it to the light source module 110.

[0060] (6) Assembled Illuminated Screens: According to actual needs, multiple assembled screen lighting modules 100 are spliced ​​together to form a large luminous screen. Through the control device, various color scene switching and brightness adjustment of the luminous screen can be realized.

[0061] In summary, the screen lighting module 100 of this utility model uses a polarizing element 120 to deflect the light emitted by the light source module 110 onto the arc-shaped light receiving surface 1505 of the screen component 150, making the light more uniform, avoiding uneven light intensity, and improving the lighting effect.
