However, the above-mentioned use of the above-mentioned rearview mirror 10 to prevent the occurrence of glare requires the driver to adjust the deflection angle of the rearview mirror 10 as required. During the adjustment process, the driver can only operate the steering wheel with one hand, which reduces driving safety.
In addition, the above method cannot prevent the oncoming vehicle from using the high beam, which will cause the driver to be dazzled.

Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] An embodiment of the present invention provides an optical converter, such as figure 2 As shown, the conversion region 01 is included, and at least one layer of the first quantum dot film 20 is arranged in the conversion region 01. The first quantum dot film 20 is a transparent film layer 202 doped with quantum dots 201, for example, in a resin material Quantum dots 2011 of a certain size or a certain distribution density are doped in (such as photores...

The embodiment of the invention provides a photoconverter and a vehicle component and relates to the technical field of dazzling prevention. The photoconverter and the vehicle component can reduce the probability of dazzling of a driver due to high beams when the high beams are used by a vehicle coming from the front part or a vehicle on the back. The photoconverter comprises a conversion area, at least one first quantum dot film is arranged in the conversion area, and the first quantum dot films are transparent film layers doped with quantum dots, wherein the absorption peak of the quantum dots is smaller than or equal to a wavelength threshold value, the emission peak of the quantum dots is larger than the wavelength threshold value, and the wavelength threshold value is larger than or equal to 490 nm and is smaller than or equal to 510 nm.
Description
technical field [0001] The invention relates to the technical field of glare prevention, in particular to a light converter and a vehicle component. Background technique [0002] With the continuous development of the automobile industry, automobiles are rapidly popularized in people's life and work, and safe driving has gradually received widespread attention. Among them, in order to improve the safety factor of driving at night, low beams and high beams are usually provided in front of the car. [0003] Among them, compared with the low beam, the high beam has a larger irradiation range, and the light beam is concentrated and the light brightness is high. Usually when the distance between two vehicles traveling in the same direction or in the same direction is about 150 meters, the driver needs to switch to low beam for lighting. However, in the actual driving process, when the driver does not switch the lighting, the high beam will directly hit the human eyes or produce...
