AI Technical Summary

Technical Problem

In the existing technology, different light functions of vehicle lights require the setting of multiple light source circuits, which results in complex drive control circuits, high costs and large space occupation, making it difficult to achieve miniaturization and integration.

Method used

At least one first driving circuit and one second driving circuit are used to drive the first and second light source components to emit light of different colors, respectively. By mixing the light colors, a third light function that meets vehicle regulations is formed, reducing the need for a dedicated light source circuit for the third light function.

Benefits of technology

The simplified vehicle lighting drive control circuit reduces manufacturing costs and space requirements, enabling a simplified design for vehicle lighting fixtures.

Abstract

This application provides an optical circuit, a control method, a vehicle lamp, and a vehicle, including at least one first driving circuit and at least one second driving circuit. The first driving circuit drives a first light source component to emit light of a first color when lit alone, which, independently or in combination with other light source components, meets the color requirements of the first light function in vehicle regulations. And / or, the second driving circuit drives a second light source component to emit light of a second color when lit alone, which, independently or in combination with other light source components, meets the color requirements of the second light function in vehicle regulations. The light of the first color emitted by at least the first light source component and the light of the second color emitted by the second light source component are mixed to form light of a third color, such that the light of the third color meets the color requirements of the third light function in vehicle regulations. Wherein, the first light color is amber or red, the second light color is blue-green or blue, and the third light color is white.
