Abstract
The present invention relates to nanostructured light emitting diodes, LEDs. The nanostructure LED device according to the invention comprises an array of a plurality of individual nanostructured LEDs. Each of the nanostructured LEDs has an active region wherein light is produced. The nanostructured device further comprise a plurality of reflectors, each associated to one individual nanostructured LED (or a group of nanostructured LEDs. The individual reflectors has a concave surface facing the active region of the respective individual nanostructured LED or active regions of group of nanostructured LEDs.
