Abstract
An illumination apparatus comprising an emitter surface and a reflector, the reflector configured and arranged to receive light from the emitter surface and to reflect at least 50% of said light back onto the emitter surface. Also an illumination apparatus comprising a first emitter surface a reflector comprising a second emitter surface, the reflector configured and arranged to receive light from the first emitter surface and to reflect a portion of said light back onto the first emitter surface. The emitter surface may be surface of an LED die.
