Description

Multifunctional multiplex vehicle lamp TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile lamps, in particular to a multifunctional multiplex vehicle lamp. BACKGROUND

[0002] Automobiles are usually provided with signal vehicle lamps at their specific positions such as the head, which are turned on when driving during the day or turning to remind pedestrians or vehicles around the motor vehicle, ensuring the purpose of safe driving of the motor vehicle.

[0003] However, the light guide structure of the vehicle lamp in the existing signal vehicle lamp is mostly single in function, and can only be used as a daytime running lamp or a turn signal lamp. At present, to realize the daytime running and turning reminding functions, two groups of vehicle lamp light guide structures with different functions need to be installed. One vehicle lamp light guide structure lights up its long light guide strip as a daytime running lamp, and the other vehicle lamp light guide structure lights up its long light guide strip as a turn signal lamp, which is relatively inconvenient. Moreover, too many vehicle lamp light guide structures will occupy too much space in the lamp housing, affecting the installation of other light function modules.
