Description
Technical Field
The embodiment of the invention relates to the technical field of illumination, in particular to an illumination system and a vehicle.
Background
The international traffic rules of automobile driving are mainly divided into left driving and right driving, and the requirements of the left driving and right driving light distribution rules are different because the cut-off line of the low beam is not symmetrical. Taking left driving as an example, the opposite vehicle meets the vehicle at the left side, so the left cut-off line is lower to prevent the driver of the opposite vehicle from dazzling to cause potential safety hazard.
At present, a lighting system of a vehicle is only suitable for one traffic rule, namely, the vehicle can only run in a left driving region or can only run in a right driving region, and the light type conversion of left driving and right driving cannot be met. Taking china as an example, a vehicle can not run from hong kong (right-hand drive) to zhughai (left-hand drive) through zhuguang australian bridge if the switching of the left-hand drive light and the right-hand drive light can not be satisfied. In the case of a projection type illumination system, the shape of the light shielding member can be switched, or the position of the light shielding member can be changed to switch between left-driving light and right-driving light, while the reflective type illumination system cannot switch between left-driving light and right-driving light.
