摘要： The present invention relates to a vehicle lamp module comprising a lens, a shading plate with a cut-off line structure, a low beam module, and a high beam module. Light emitted by the low beam module is suitable for interception by the shading plate and then emission to the lens to form a low beam type. Light emitted by the high beam module is suitable for interception by the shading plate and then emission to the lens to form a main high beam type located above a light and shade cut-off line. The vehicle lamp module further comprises an auxiliary high beam module. Light emitted by the auxiliary high beam module is suitable for interception by the shading plate and then emission to the lens to form an auxiliary high beam type located below the light and shade cut-off. The vehicle lamp module provides high beam with more uniform brightness.

The partition has a curvy end face and an opening. The opening of the partition faces toward the optical lens. Light emitted by at least one low beam light source is converged through the low beam condenser, then transmitted from the upper position of the partition to the bottom of the partition, and eventually sent to the lower part of the optical lens. Light emitted by at least one high beam light source is converged by the high beam condenser, transmitted from the bottom of the partition through the light guide channel to the top of the partition, and then sent to the upper part of the optical lens.
