This invention is an illumination system that incorporates a light emitting diode and a partially reflecting optical element. The Slicing Table of Fault Distribution is generated at each booting or memory-testing, and the elemental range of the number of detected defects is formed. Embodiments using high pressure air injection to sustain combustion are also disclosed. In a first operation mode the heater may be turned on so that heating is supplied by both the heat pump and the heater to provide for rapid drying.
