Title:
VEHICLE LIGHT DYNAMIC CONTROL METHOD, SYSTEM THEREOF, AND VEHICLE LIGHT
Document Type and Number:
WIPO Patent Application WO/2020/010932
Kind Code:
A1
Abstract:
A vehicle light dynamic control method and a device thereof, employing a vehicle light dynamic control system comprising a light source and a lens. The light source is a surface light source, such as an LED light-emitting chip surface light source. An optical axis of the surface light source is aligned with an incident surface of the lens. The lens is used to perform primary collimation on light that has been emitted by the surface light source and that has undergone approximately Lambertian divergence, such that the light, having passed through the lens, propagates in a substantially parallel manner, so as to result in a bright beam that forms a shape on a front screen. The surface light source is disposed in front of or behind the focal point of the lens, so as to be out of focus. The amount by which the surface light source is out of focus with respect to the lens can be adjusted to change the shape of the light on the front screen; that is, achieving dynamic illumination, so as to provide different light shapes according to vehicle speed and road conditions. The invention improves illumination and driving safety, and reduces costs.
