Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, an optical structure of a steering wheel intelligent driving indicator light is arranged on a steering wheel and includes an indicator light cover 1, a first RGB three-chip light source LED2, a second RGB three-chip light source LED3, a light guide 4, and a bracket 5.

The middle of the indicator light mask 1 is a light-transmitting part 6; the outer ring of the light-transmitting part 6 is a light-proof part 7; the light guide 4 is fixed on a support 5; the bracket 5 is fixed on a steering wheel; a first RGB three-chip light source LED2 and a second RGB three-chip light source LED3 are disposed at both ends of the light guide 4. The first RGB three-chip light source LED2 and the second RGB three-chip light source LED3 are connected with a PCBA board; PCBA board externally arranges the back of support 5 in, and is external to be favorable to the heat dissipation.

The curvature and shape of the light guide 3 are consistent with those of a steering wheel, and the space utilization rate can be effectively improved.

The indicator lamp face mask 1 adopts a double-color injection molding process, the light-tight part 7 is made of a white light-reflecting material, and the light-transmitting part 6 is made of a black light-transmitting material. The indicating lamp mask 1 can also be suitable for decorative masks of door guard plate atmosphere lamps, instrument panel atmosphere lamps and the like, and patterns can be designed into shapes of diamond panes, stars, wave stripes and the like.
