ABSTRACT:
An electroluminescent device is provided with two semiconductor crystals, in each of which an electroluminescent junction is formed, which junctions can alternately be energized from an external current source. One of the semiconductor crystals is of the p
-type and the other semiconductor crystal is of the n/p-type, while both crystals are provided on the bottom of a reflecting cavity of a single metal support.
