[0002] A photoconductor, also known as an optical waveguide, is a structure that can conduct light from one place to another. A photoconductor is usually made of a material with good light-guiding properties. A photoconductor can effectively direct the light emitted by an LED to the desired location. Existing automobile rearview mirrors are generally equipped with a photoconductor, which is used in conjunction with the automobile's blind spot monitoring system. When the vehicle radar detects a vehicle approaching in the vehicle's blind spot, the photoconductor emits a bright light under the control of the blind spot monitoring system to alert the driver.

[0003] After searching, it is disclosed in the Chinese patent publication number CN105083108B and the patent name of the lighting unit that the light-transmitting window also forms a light conductor, which is used to transmit light from the coupling part at the printed circuit board along the light conductor until it finally reaches the decoupling part in the decoupling area at the end of the light conductor, and inputs the light of the LED mounted on the printed circuit board. This light conductor is a light-guiding structure. However, when the light conductor in the above-mentioned lighting unit is in use, when the vehicle passes through a narrow road, the light conductor is located at the extended end of the vehicle's rearview mirror, and the outside of the light conductor lacks a protective structure. It is easy to be damaged when it is scratched and squeezed, resulting in abnormal use of the light conductor. Utility Model Content

[0004] Based on this, it is necessary to provide a dual-core rearview mirror optical conductor to address the problem that the optical conductor is easily scratched and damaged during vehicle driving.

[0006] In one embodiment, the interior of the light guide bar is a hollow structure, a light strip is inserted into the interior of the light guide bar, a fastener for fastening the light strip is provided on one outer wall of the light guide bar, and the fastener is screwed with the light guide bar via threads.

[0007] In one of the embodiments, a socket is fixed at one end of the light guide strip, a through hole is opened in the middle of the surface of the socket, the light strip can pass through the through hole and extend to the inside of the light guide strip, a plug is fixed at one end of the light strip, a socket is also opened on the surface, and a plug rod corresponding to the plug is provided on the surface of the plug.

[0008] In one of the embodiments, a clamping plate is fixed to one side surface of the light guide strip, and a clamping seat matching with the clamping plate is disposed on the inner wall of the rearview mirror housing.

[0010] In one of the embodiments, a sealing strip is further provided between the light guide strip and the rearview mirror housing.

[0011] When the utility model is in use, the optical conductor can be protected by the provided protective component, and the end edge of the optical conductor is covered by the protective component, thereby avoiding the problem that the outer wall of the optical conductor is squeezed by external hard objects.
