In order to obtain a more reasonable and good diffusion of light, the present invention comprises a first light-transmitting plate and a second light-transmitting plate, and a light-transmissive paper is fixedly fixed to the first light-transmitting plate and the second light-transmitting plate. Between the plates, the light is sequentially passed through the first transparent plate, the transparent paper and the second transparent plate to obtain suitable diffusion, and finally the light penetrates the mask to form a uniform and soft luminous effect.

In order to obtain a good seal between the base and the base sealing cover, the present invention applies a sealant between the base sealing cover and the base.

In a preferred embodiment, the outer surface of the mask is plated to form a light-transmissive plating layer on the outer surface of the mask; thereby, when the light source module is not energized, the outer surface of the mask has metallic luster. Improve the aesthetic appearance of the appearance; when the light source module is powered and illuminated, the light can penetrate the plating layer of the mask to form a glowing text, figure or symbol.

The base and mask of the nameplate of this creation can be made by plastic injection molding technology.

In order to enable the light source module to be stably disposed on the bottom surface of the base, an embodiment of the present invention can provide at least one positioning tip on the bottom surface of the inner space of the base, and at least one pair of positioning tips should be disposed on the circuit board of the light source module. The hole, when the light source module is installed in the base, allows the positioning tip to pass through the positioning hole to position the circuit board on the bottom surface of the inner space of the base.

The non-hollowed hole portion of the mask of the present car nameplate constitutes a character, figure or symbol that can be penetrated by light.

The above-mentioned signature plate structure has the advantages of reasonable structural design, good luminous effect and uniformity, energy saving and beautiful appearance, and can realize different luminous effects of characters, figures, patterns or symbols.
