The embodiments described below are exemplary by referring to the drawings for the purpose of illustrating the utility model and are not to be construed as limiting the utility model.

The preferred embodiments provided by the utility model are: referring to fig. 1 to 6, a uniform light emitting structure of a light transmitting plate includes a light guide plate 1 and a light transmitting plate 2; the light guide plate 1 is provided with a plurality of incisions 11, and the incisions 11 penetrate through the light guide plate 1 to enable the light guide plate 1 to form a vacancy locally; an indication part 21 is arranged on the end face of the light-transmitting plate 2, and the indication part 21 is composed of indication characters, indication patterns or combination of the indication characters and the indication patterns. The light guide plate 1 is in contact with the light-transmitting plate 2 so that the slit 11 approaches the indication portion 21 to guide the light rays approaching the indication portion 21 of the slit 11 to be emitted from the slit 11.

The light-transmitting plate 2 comprises a front surface 22 and a back surface 23, and the light guide plate 1 is connected to the back surface 23; the indication portion 21 is provided on the surface 22, and the indication portion 21 is protruded with respect to an end surface of the surface 22. The light-transmitting plate 2 is of an integrated structure, the indication part 21 and the light-transmitting plate 2 are made of the same material, when the light-transmitting plate 2 is connected with the light-guiding plate 1, the notch 11 is adjacent to the edge position 27 of the indication part 21, and the notch 11 is positioned outside the vertical projection plane of the indication part 21 relative to the light-guiding plate.

The light-transmitting plate 2 is provided with a light-emitting plate 3, the light-emitting plate 3 is used for generating light, the light-emitting plate can adopt a conventional LED lamp strip, the light-guiding plate 1 is connected with the light-transmitting plate 2 and is arranged on the light-emitting plate 3, the light-emitting plate 3 is provided with a bayonet 31, the bottom of the light-transmitting plate 2 extends out of the bayonet 26, and the light-transmitting plate 2 is embedded on the bayonet 31 of the light-emitting plate 3 through the bayonet 26 so as to limit the position of the light-transmitting plate 2 to prevent movement.

The end face of the light guide plate 1 is a flat end face, and the light guide plate 1 can be made of polyethylene, polycarbonate, polymethyl methacrylate and other materials, so that the end face of the light guide plate has a flat and smooth surface; the transparent plate 2 is made of acrylic; the light guide plate 1 is connected with the light-transmitting plate 2, the end face of the light guide plate 1 is attached to the back face 23 of the light-transmitting plate 2, the connected light-transmitting plate 2 and the light guide plate 1 are placed on a light source, light generated by the light source is transmitted into the light-transmitting plate 2, the light is scattered in the light-transmitting plate 2, one part of the light is transmitted out of the surface 22 to enter the indicating part 21 and is continuously scattered in the indicating part 21, and the other part of the light is scattered to the light guide plate 1 on the back face 23 and is diffusely reflected through the light guide plate 1, so that bright extension is realized, and meanwhile, the diffusely reflected light can enter the light-transmitting plate 2 again. Since the indicating portion 21 is raised with respect to the end face of the surface 22, the indicating portion 21 has a rim position 27; if the light guide plate is not provided with a notch, as shown in fig. 4, the internal and external light rays at the edge position will be refracted simultaneously at both sides of the edge position, so that the edge position of the indication part 21 is relatively too bright, and the overall brightness is uneven. Therefore, in this structure, as shown in fig. 5, the light guide plate 1 is provided with a plurality of slits 11, when the light guide plate 1 is connected with the light-transmitting plate 2, the positions of the slits 11 correspond to the edge positions of the indication parts 21 of the light-transmitting plate 2, so that part of light rays in the light-transmitting plate can directly penetrate out of the slits 11, so as to weaken the influence on the outer side of the edge positions, avoid local excessive brightness, and make the whole light transmission of the light-transmitting plate 2 more uniform.
