Vehicle lamp driving method and device, and vehicle

Abstract

The present invention provides a vehicle lamp driving device and method, and a vehicle. The lamp driving device is used for a vehicle, the vehicle comprises a high beam module and a low beam module, the lamp driving device comprises a driving control module and a voltage regulating module, the driving control module sends a control signal to the voltage regulating module, the voltage regulating module sends a first voltage signal to the low beam module, controls the low beam module to be turned on, and sends a second voltage signal to the high beam module to control turning-on of the high beammodule. The splitting high beam module and low beam module are arranged to control independent light emitting respectively, compared to the prior art, a solenoid valve and a baffle in a traditional vehicle lamp are omitted to provide more spaces and creativity for the design of the whole lamp shape so as to simplify the design difficulty and reduce the cost of the whole lamp; and moreover, compared to the traditional mechanical control of high-low beam switching, the switching response speed is improved, and the high-low beam individuation demand is met.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle lamp driving method, a vehicle lamp driving device and a vehicle. Background technique [0002] LED car lights have the advantages of small size, low power consumption, long service life, high brightness, low heat, and environmental protection. They have been popularized not only in high-end cars, but also in low-end and mid-end cars. but, [0003] The far and near beams of the current LED car lights are the same light source, and the switching between the far and near beams and the low beams needs to be achieved through solenoid valves and baffles. The existence of these mechanical structures not only increases the difficulty of LED module design, but also improves 5 The cost of the LED module; and the slow movement speed of the mechanical structure, which leads to the problem of long switching response delay. Contents of the invention [0004] In view of this,...
