Automobile exterior rear view mirror blind spot warning indication device
First Claim
1. An indication device for a rearview device of a vehicle, comprising:
- a light source assembly for emitting an indicating light beam, anda light guide member for reflecting the indicating light beam to a marking region, wherein the light source assembly and the light guide member are disposed in a mounting cavity of a carrier plate, the light source assembly comprises a printed circuit board (PCB) and a plurality of juxtaposed light sources mounted on the PCB, and wherein the light guide member comprises;
a plurality of wedge-shaped bosses arranged side by side along an axis on the light guide member corresponding to a setting direction of the PCB;
one side of each of the plurality of wedge-shaped bosses has a light incident end surface for aligning with a corresponding light source;
an upper surface of each of the plurality of wedge-shaped bosses includes a light-reflecting side having an optical pattern for reflecting and scattering and at least a portion having one of a wave-like configuration or a combined step-like and wave-like configuration;
the light-reflecting side having the optical pattern is an upward convex arc surface;
a lower surface of the each of the plurality of wedge-shaped bosses has a light emitting side; and
an outermost wedge-shaped boss has a largest curvature of the light-reflecting side compared to the remaining plurality of wedge-shaped bosses arranged side by side and has a longest length of the light-emitting side compared to the remaining plurality of wedge-shaped bosses arranged side by side.

Abstract
A blind spot warning indication device for an exterior mirror of an automobile includes a light guide member. A plurality of wedge-shaped bosses are arranged side by side along an axis on the light guide member corresponding to a setting direction of the PCB. One side of each of the plurality of wedge-shaped bosses has a light incident end surface for aligning with a corresponding light source. An upper surface of each of the plurality of wedge-shaped bosses includes a light reflecting side having an optical pattern for reflecting and scattering. The reflecting side having the optical pattern is an upwardly convex arc surface. A lower surface of the wedge-shaped boss has a light emitting side. The outermost wedge-shaped boss has the largest curvature of the light-reflecting side compared to the other wedge-shaped bosses arranged side by side, and the outermost wedge-shaped boss has the longest length of the light-emitting side compared to the other wedge-shaped bosses arranged side by side. The device has the functions of reflection and scattering at the same time. The uniformity of the emitted light at the front surface and certain angles is better, and the warning effectiveness is improved. The LOGO pattern can be better combined with the emitted light.
