The invention relates to a lighting device for a motor vehicle, comprising at least one light source (10) and an elongate light guide (1), which is delimited along its longitudinal extent by side surfaces (2, 3), which is designed for total reflection conduction of light of the at least one light source (10) in a light propagation direction, the at least one light source (10) has a light propagation direction which corresponds to a longitudinal extension of the light guide (1), light of the at least one light source (10) can be coupled in via a coupling-in surface on an end face of the light guide (10), and a coupling-out structure for coupling-out of light is provided on side faces (2, 3) of the light guide (10), the light exits from the light guide (1) in the light propagation direction through the exit regions of the side surfaces (2, 3) without the total reflection condition. The invention relates to a lighting device (1) having a coupling-out structure (2, 3) which is formed by a plurality of non-intersecting coupling-out regions (9) which are surrounded by regions of the side surfaces (2, 3) which are provided for the conduction of total reflection of light, the lighting device being designed in such a way that the light which is coupled out by the non-intersecting coupling-out regions produces a light pattern (LG) on a surface (8) which is provided adjacent to the light conductor (1), each outcoupling region (9) is associated with a further element (L) of the light pattern (LG), said further element being generated by the outcoupled light of the associated outcoupling region (9).

    本发明涉及一种用于机动车的照明装置,其具有至少一个光源(10)和长形的光导体(1),所述光导体沿其纵向范围通过侧面(2、3)限定,所述光导体(1)设计用于所述至少一个光源(10)的光沿光传播方向的全反射的传导,所述光传播方向对应于光导体(1)的纵向延伸,所述至少一个光源(10)的光通过在光导体(10)的端侧上耦合输入面可耦合输入,并且在光导体(10)的侧面(2、3)上设置用于光的耦合输出的耦合输出结构,所述光沿光传播方向通过侧面(2、3)的出射区域在取消全反射条件的情况下从光导体(1)中出射。所述耦合输出结构通过多个不相交的耦合输出区域(9)形成,所述耦合输出区域由侧面(2、3)的设置用于光的全反射的传导的区域包围,照明装置设计为使得由不相交的耦合输出区域的耦合输出的光在相邻于光导体(1)设置的面(8)上产生光图形(LG),每个耦合输出区域(9)配置给光图形(LG)的另外的元素(L),所述另外的元素由所配置的耦合输出区域(9)的耦合输出的光产生。
