The invention relates to a lighting module for a motor vehicle (1), comprising: a light source (2); projection optics (3) which are designed to project the light field (S) onto the ground. According to the invention, the light emitting module further comprises an element having a variable light transmittance positioned between the light source and the projection optics, said element having a variable light transmittance comprising at least one first portion and at least one second portion. Each of these portions has a different light transmittance such that image sectors respectively formed by the first portion and the second portion have the same luminous intensity.

    本发明涉及一种用于机动车辆(1)的发光模块,该发光模块包括:‑光源(2);‑投射光学器件(3),该投射光学器件被设计成将光场(S)投射到地面上。根据本发明,发光模块进一步包括定位在光源与投射光学器件之间的具有可变透光率的元件,所述具有可变透光率的元件包括至少一个第一部分和至少一个第二部分。这些部分中的每个均具有不同的透光率,使得由第一部分和第二部分分别形成的图像扇区具有相同的发光强度。
