Light guide element

The invention relates to a light guide element (30) for a lighting device (28), in particular for a display device (22), wherein the light guide element is at least partially made of a light-transmissive material, and wherein the light guide element has at least one light coupling-in surface (32), which is designed to couple in a light beam (42) into the light guide element. Furthermore, at leastone recess (40) having a convexly shaped first face (44) is introduced into the light guide element, wherein a first surface of the at least one recess, which is convexly formed, is oriented relativeto the at least one light coupling-in surface, the distance (48, 58, 60) between the first surface of the at least one recess, which is convexly formed, and the at least one light coupling-in surfaceis designed as a shortest distance (48, 58, 60) relative to the distance between the at least one recess and the at least one light coupling-in surface. 本发明提出一种用于照明装置（28）、特别是用于显示设备（22）的光导元件（30），其中所述光导元件至少部分地由可透光的材料构成，并且其中所述光导元件
