The semiconducror lamp - as a source of illumination - an analog of vacuum and electroluminescent lamps

The composition light and electrical characteristic and parameter vacuum. electroluminescent and semiconductor lamps, illuminated white light has been made. The white light semiconductor lamps get by mixing blue electroluminescence InGaN heterostructure and yellow photoluminescence alumo-ittrey granat. The main advantage of semiconductor lamps were high quantum efficiency, long life time, (more 100 000 hour), ecology safety and radiational hardness. The construction and technology elements semiconductor lamps - analogs vacuum and electroluminescent sources of illumination - has been described.
