Optical device and method for producing same

Abstract

The invention relates to a method for producing an optical device () comprising at least one light source (), at least one light guide () having an entry surface () facing the light source (), and having an exit surface () formed at an end of the light guide () lying opposite the entry surface (), in order to allow light entering into the light guide () to exit same, and a projection optics () which is designed to project the light exiting the exit surface () onto a projection plane () provided at a distance from and at an angle of inclination (γ) relative to a main direction of emission (Z) of the optical device (). The method comprises the following steps: specifying a target distribution of the illuminance in the image () projected into the projection plane () by the projection optics (); determining a non-homogenous distribution of the illuminance (Ev) of the light across the exit surface () from the distribution to be specified of the illuminance in the image () projected into the projection plane (); determining a three-dimensional shape of the at least one light guide () with which the non-homogenous distribution of the illuminance (Ev) of the light across the exit surface () is generated when light is emitted by the at least one light source (); and producing the light guide () with the three-dimensional shape and assembling the components of the optical device ().
