Abstract
An illumination unit includes: at least one optoelectronic emitter unit which emits electromagnetic radiation via a light-emitting surface, and a photonic structure for beam shaping of the electromagnetic radiation before it exits via the light emitting surface, wherein the photonic structure shapes the electromagnetic radiation such that the electromagnetic radiation has a certain far field.
Claims10
An optoelectronic device, comprising:
- an arrangement comprising a plurality of light sources for generating light emerging from a common light emitting surface from the optoelectronic device;
- and
- one common and uninterrupted photonic structure disposed between the light emitting surface and the plurality of light sources,
- wherein the one common and uninteruppted photonic structure is a photonic crystal that is arranged with respect to a plane parallel to the light-emitting surface independently of the positioning of light sources of the plurality of light sources.
