In the guide-lighting opening area of the first light insulation pad and the second light insulation pad.
Further, the area at light guide light extraction end is less than the sectional area of light guide connection structure, while light guide connection structure
Sectional area is less than the area of light guide light inlet, and the point of switch indication light is uniformly improved to ensure that light guide light extraction end is integrally lighted
Bright uniformity.
Further, light guide light inlet or light guide light extraction end are equipped with dermatoglyph, improve the diffusion of light guide body, and then improve
Switch indication light lights uniformity.
Further, light guide body by transparent material and scattering material by two-shot molding process injection molding, to improve
Light guide light extraction end integrally lights uniformly, and then improves switch indication light and light uniformity.
Further, light guide light inlet is equipped with diffusion decorative pattern, and that improves switch indication light lights uniformity.
Further, diffusion decorative pattern is uniform by the protrusion of tetrahedron shape, the protrusion of arc surface shape or niblet decorative pattern
It is distributed.
Advantageous effect：
1. the switch indication light light guide of the present invention, is determined by light guide light inlet, light guide connection structure, light guide light extraction end and light guide
Bit architecture is constituted, and light guide body is fixed in the light insulation pad of switch indication light, and light insulation pad is divided into two parts, increases light guide entering light
End area, that improves switch indication light lights uniformity.
2. the present invention light guide body is made it is trapezoidal, i.e., the area at light guide light extraction end be less than light guide connection structure section
Product, the sectional area of light guide connection structure are less than the area of light guide light inlet, and then that improves switch indication light lights uniformity.
3. the present invention adds dermatoglyph on light guide light inlet or light guide light extraction end, the material of light guide body changes from transparent material
At double-shot moulding, plus diffusion decorative pattern on light guide light inlet, that improves switch indication light lights uniformity.
