ABSTRACT:
In an LED illumination system for illuminating a surface (5) with a predetermined illumination distribution, comprising at least one LED semiconductor body (2) which emits light symmetrical to a main beam direction (9) of the LED semiconductor body (2), illumination optics (4) are disposed between the at least one LED semiconductor body (2) and the surface (5) that is to be illuminated, which optics deflect the emitted light (6) asymmetrically relative to the main beam direction (9) of the LED semiconductor body (2). This makes it possible to purposely adjust the illumination of the surface (5) regardless of its shape.
