Abstract

An integrated LED device is provided. The LED device includes a substrate. The LED device includes a semiconductor material including a light generating layer and positioned on the substrate. The semiconductor material and/or the substrate are configured to control light internally to output quasi-collimated light from a light emitting surface of the LED device. The LED device includes an optical component positioned at the light emitting surface and configured to receive quasi-collimated light exiting the light emitting surface and to alter one or more optical properties of at least some beams of the quasi-collimated light.
