[0034] Please refer to Figures 1-7 , the present utility model provides a light-emitting physical pixel unit for a mechanical physical pixel screen, including: a power driving mechanism 11, a bracket 12, a load shape 13 and a light source assembly 14;

[0035] Wherein, the bracket 12 is used to fix the power driving mechanism 11 and the load shape 13; the load shape 13 is fixedly installed on the power driving mechanism 11;

[0036] A light source assembly 14 that emits light evenly is detachably installed on the load shape 13. Preferably, a structure such as a snap can be used to achieve the detachable installation of the light source assembly 14, and a transparent or translucent light transmissive plate 144 for light to pass through is provided on the outer surface of the load shape 13, and the load shape 13 can present changes in physical pixel size or brightness level or color.

[0037] Furthermore, wherein, as Figure 5As shown, the light source assembly 14 includes: a light source 141, a light guide plate 142, a light diffusion plate 143 and a light-transmitting plate 144. The light guide plate 142 is installed on the outside or inside of the load shape 13. The light sources 141 are installed on both sides or the bottom of the light guide plate 142. The light diffusion plate 143 is installed on the top of the light guide plate 142. The light emitted by the light source 141 is evenly dispersed and emitted through the light diffusion plate, so that the light beam is dispersed and the overall brightness is improved. The light-transmitting plate 144 is installed on the outside of the light diffusion plate 143 to play the role of light transmission and protection of the light source module, such as dustproof and waterproof functions. Since the load shape comes with a light source module that emits light evenly, it is convenient for the mechanical physical pixel screen to display images at night or in places with insufficient light. Preferably, the light source 141 is an LED light-emitting sheet or an LED light strip, and the light-transmitting plate 144 is an acrylic plate. As shown in FIG. Figure 5 As shown, two LED light strips are respectively installed on the two sides of the light source assembly 14, and the light-transmitting plate 144 is snap-connected to the outer surface of the load shape 13 by means of buckles.

On the inner and outer sides of the two opposite surfaces of the through groove, a number of opposite convex portions 121 are uniformly arranged along the direction of the through groove for fixing the circuit. Specifically, the circuit can be clamped between the convex portions 121 of the inner and outer layers, making the bracket thin and light, convenient for storing the circuit, and the circuit is neat.

[0043] Further, the specific shape of the load model 13 is not limited and can be sheet-shaped, box-shaped, tubular, or any other shape; and the surface of the load model 13 is a plane, a curved surface, or other shapes.

[0044] Further, the number of brackets 12 corresponding to each light-emitting physical pixel unit is one or two. To improve the stability of the load movement and the service life of the power mechanism, two brackets can be selected. Of course, if cost reduction is considered, one bracket can also be considered. It can be selected according to the actual application situation.
