Abstract: A light emitting diode device which, in use, has its light emitting region occupying a plane substantially perpendicular to a plane occupied by the surface on which the device is mounted. The primary light emission directions of the light emitting region are parallel to the surface on which the device is mounted. The device may have both its p-type and n-type semiconductor layers passivated by a layer or layers of light transmissive materials. There is a method for fabricating and mounting such a device. A plurality of the light emitting diode devices can be used in a lighting assembly for providing a plurality of independently controllable lit regions.
