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.
Claims18
An LED illumination system for illuminating a surface with a predetermined illumination intensity distribution, the LED illumination system comprising:
- at least one LED element emitting light symmetrically relative to a main beam direction of said LED element;
- and
- illumination optics disposed between said LED element and the surface to be illuminated, said illumination optics having a concave surface facing said LED element, a convex surface facing the surface to be illuminated, and deflecting emitted light asymmetrically relative to the main beam direction of said LED element.
An LED illumination system comprising:
- at least one LED element having a surface-mountable LED component with a LED plastic housing, said at least one LED element emitting light symmetrically relative to a main beam direction of said LED element;
- and
- illumination optics disposed between said LED element and a curved surface to be illuminated, said illumination optics deflecting emitted light asymmetrically relative to the main beam direction of said LED element to illuminate said curved surface with a substantially uniform illumination intensity distribution.
