Detailed Description
The overall structure and slope diagram of the thick-wall light guide structure based on the transparent material are shown in fig. 1 and 2.
The thick-walled light guide structure includes: a light guide a1, a light guide b2, an upper liner frame 3, a light source 4, a circuit board 5, an upper holder 6, a lower holder 7, a lower cover plate 8, and a lower liner frame 9;
the light guide b2 is arranged below the light guide a1, the light guide b2 is in seamless connection with the light guide a1, the upper portion of the light guide a1 is connected with one end of the upper lining frame 3, the other end of the upper lining frame 3 is connected with the upper portion of the upper support 6, the circuit board 5 is arranged below the upper support 6, the light source 4 is arranged below the circuit board 5, light rays emitted by the light source 4 can directly enter the light guide a1, one end of the lower cover plate 8 is connected with the lower end face of the light guide b2, the other end of the lower cover plate is connected with the lower support 7, and the lower end face of the light guide b2 is further provided. The specific structure is shown in fig. 3.
The light guide a1 is formed by first injection molding, and the light guide b2 is formed by second injection molding after the first injection molding of the light guide a1, and the lower cover plate 8 plays a role in covering the mounting structure below, so that the structure is prevented from leaking to the maximum extent.
Fig. 4 is a schematic diagram of the optical path of the thick-walled light guide, which is composed of the condenser 11, the reflecting surface a21, the corn-shaped optical surface 12, the upper surface 13 and the lower surface 14.
The light source 4 (light emitting diode or laser diode) emits light that passes through the condenser 11 and then irradiates the reflecting surface a21 (the range defined by the broken line), and the reflected light is emitted from the surface of the nanoparticle-shaped optical surface 12 through the thick-walled portion of the thick-walled light guide, thereby providing a relatively uniform optical effect on the surface.

Fig. 7 shows a thick-walled light guide structure, light emitted from a light source 4 is reflected by a reflecting surface a21 and then is irradiated onto the front surface kernel optical structure 12, and a light path formed according to the structure finally causes a local over-brightness phenomenon on a visible surface, resulting in an uneven optical effect.
This concludes the description of the embodiments of the present invention.
