Abstract
In an embodiment a projection device includes an LED array on which a plurality of micro LEDs is arranged at regular intervals, projection optics spaced from the LED array and configured to receive light emitted from the LED array and to project the light onto a projection surface and a light collecting structure comprising individual protrusions, wherein the protrusions are optically coupled to individual LEDs of the LED array such that they restrict an angular space of light emitted by the individual LED and/or make an emission uniform.
