摘要： The present invention relates to a light emitting device that achieves a light screen effect, comprising a light source (1) and a light guide (2). The light guide (2) is an elongated part, the light source (1) being arranged at one axial end of the light guide (2), the light guide (2) having an uneven emitting surface (4), wherein the light emitted by the light source (1) enters into the light guide (2) and is reflected/refracted with a set pattern on a corresponding curved or flat face, thereby forming a bright and dark pattern of light and shade. The light guide (2) has an uneven emitting surface (4) capable of reflecting/refracting light on a reflecting curved face and/or a LENS face inside a grille, such that a user can see the light reflected/refracted, which is bright and dark pattern of light and shade, from the outside of an automobile
