1. A system, comprising: an interactive head-mounted device including an optical assembly comprising a light transmissive illumination system, the optical assembly being configured to display virtual content and to enable viewing of at least a portion of a surrounding environment, an integrated processor for processing the virtual content for display, an integrated image source for introducing the virtual content to the optical assembly, the integrated image source including a reflective image display, and an LED lighting system coupled to the light transmissive illumination system, wherein the light transmissive illumination system comprises a planar illumination facility comprising a waveguide having an end configured to input light from the LED lighting system, and an optical imperfection formed in the planar illumination facility, the optical imperfection being configured to direct light from the LED lighting system input at the end of the waveguide toward a face of the waveguide that is transverse to the end of the waveguide to output the light from the waveguide toward the reflective image display to uniformly irradiate the reflective image display to produce an image, and wherein the reflective image display is configured to reflect the image through the waveguide for display.
