[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figure 1-3, an iron plate structure for improving the light effect of multi-primary color mixed light, including an iron plate body, the iron plate body including a fixed substrate 1, a light source board 2 is provided at the bottom of the fixed substrate 1, for installing the light source board 2, the light source board 2 can be a standard multi-primary color LED light source PCB board, on which LED chips of various colors are integrated, a focusing baffle ring 3 is provided on the periphery of the light source board 2, the focusing baffle ring 3 can be an iron ring, which can be integrally formed with the fixed substrate 1 to strengthen the connection strength between the focusing baffle ring 3 and the fixed substrate 1; the focusing baffle ring 3 and the fixed substrate 1 form a mixing area for limiting the diffusion of light emitted by the light source board 2 The focusing ring 3 is provided with a light mixing unit 4, which includes a plurality of light mixing beads 41. The plurality of light mixing beads 41 are evenly distributed on the inner wall of the focusing ring 3 to realize multiple reflections of the light in the focusing ring 3 and promote the uniform mixing of the light. The light mixing beads 41 can be formed by stamping after the inner surface of the focusing ring 3 is specially treated; the light mixing beads 41 can be semi-spherical beads, which can increase the area of ​​light reflection and can effectively reflect the light at different angles, thereby further improving the uniform mixing of the light.

[0021] In some embodiments, a mounting groove 11 is provided at the bottom of the fixed substrate 1, and a light source board 2 is provided in the mounting groove 11. The mounting groove 11 is symmetrically provided with two mounting holes 12 to facilitate fixing the light source board 2. The specific structures of the mounting groove 11 and the mounting holes 12 and the fixed installation of the light source board 2 on the fixed substrate 1 are all prior arts and will not be repeated here. The mounting groove 11 can be stamped by the fixed substrate 1, and while realizing the fixed installation of the light source board 2, it can serve as a reinforcing rib on the fixed substrate 1, thereby enhancing the connection strength of the fixed substrate 1, and thereby improving the stability of the iron plate body during installation.

[0022] In some embodiments, a plurality of light-mixing beads 41 are evenly disposed on the bottom surface of the fixed substrate 1, and can be disposed on the inner wall and side wall of the mounting groove 11, so that the light emitted by the light source panel 2 can be reflected in all directions in the mixing area, thereby improving the uniformity of light mixing and improving the reflection of light by the bottom surface of the fixed substrate 1, thereby reducing the loss of light during propagation and improving the utilization rate of light.

[0023] In some embodiments, a reflective layer is provided on the bottom surface of the fixed substrate 1 and the inner surface of the focusing baffle ring 3. The reflective layer may be an electroplated film made of a high-reflectivity material, may be an aluminum-plated film, or may be a silver-plated film, so as to minimize light loss and improve light reflection efficiency. A reflective layer may be evenly coated on the bottom surface of the fixed substrate 1 and the inner surface of the focusing baffle ring 3 by vacuum coating technology to ensure that the surface of the reflective layer is smooth and free of bubbles and scratches, so as to improve light reflection efficiency.

[0024] In some embodiments, a mounting groove plate 5 is provided at one end of the focusing baffle ring 3 away from the fixed substrate 1. The mounting groove plate 5 can be a ring plate wrapped around the outer surface of the focusing baffle ring 3, which can enhance the fixing strength of the focusing baffle ring 3; a plurality of fixing holes 51 are provided on the mounting groove plate 5, which is convenient for subsequently fixing the iron plate to the lamp housing through screws or other fasteners.

[0025] The specific working principle is as follows:

[0026] When the multi-primary color LED light source is lit on the light source board 2, the emitted light is first limited to a certain range by the focusing ring 3 and guided to propagate in a specific direction. Then, the light encounters the light mixing beads 41 on the inner wall of the focusing ring 3. Since the light mixing beads 41 are semi-spherical in shape, the light is reflected multiple times on its surface, and lights of different wavelengths are mixed with each other in this process, forming a uniform and rich light color effect.

[0027] At the same time, the reflective layer at the bottom of the fixed substrate 1 and the inner surface of the focusing baffle ring 3 will efficiently reflect the light that does not directly pass through the mixing beads 41, ensuring that the light is fully utilized, effectively reducing the loss of light during the propagation process, improving the utilization rate of light, and further improving the overall lighting effect.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
