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.

Claims (16)

1 . 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.

2 . The optoelectronic device according to claim 1 , wherein the one common and uninterrupted photonic structure is designed for beam shaping of the light generated by the light sources, in particular in such a way that the light emerges at least substantially perpendicularly from the light emitting surface.

3 . The optoelectronic device according to claim 1 , wherein the device is an array comprising a plurality of pixels as light sources arranged in a layer, and that the photonic crystal is arranged or formed in the layer.

4 . The optoelectronic device according to claim 1 , wherein the device is an array comprising as light sources a plurality of pixels arranged in a first layer, and that the photonic crystal is arranged in a further, second layer, the second layer being located between the first layer and the light emitting surface.

5 . The optoelectronic device according to claim 1 , wherein the device comprises as light sources a plurality of LEDs arranged in a first layer, and that the photonic crystal is arranged in the further, second layer, the second layer being located between the first layer and the light emitting surface.

6 . The optoelectronic device according to claim 1 , wherein each of the light sources comprises a recombination zone and the photonic crystal is located close to the recombination zones in such a way that the photonic crystal changes an optical density of states present in the region of the recombination zones, in particular in such a way that a photonic band gap is generated for at least one optical mode with a propagation direction parallel and/or at a small angle to the light emitting surface.

7 . The optoelectronic device according to claim 1 ,

wherein the photonic crystal is a two-dimensional photonic crystal which exhibits a periodic variation of an optical refractive index in two mutually perpendicular spatial directions spanning the plane.

8 . The optoelectronic device according to claim 1 , wherein said photonic structure comprises a plurality of pillar structures extending at least partially between said light emitting surface and said plurality of light sources, each pillar being associated with a corresponding light source and aligned with said light emitting surface as viewed in a direction perpendicular thereto.

9 . The optoelectronic device according to claim 8 , wherein the arrangement comprises as light sources a plurality of LEDs arranged in a first layer, and that the pillars are arranged or formed in a further, second layer, the second layer being located between the first layer and the light emission surface.

10 . A method of manufacturing the optoelectronic device according to claim 1 ,

wherein the arrangement having the plurality of light sources for generating the light emerging from the common light emitting surface from the optoelectronic device is provided or fabricated; and

the one common and uninterrupted photonic structure is disposed between the common light emitting surface and the plurality of light sources.
