Beschreibung
Zusammenfassung:	A matrix light source intended to be supplied with a voltage and having a plurality of electroluminescent semiconductor element-based elementary light sources and a common substrate in contact with an integrated circuit. The integrated circuit includes, for each elementary light source, a switching device for selectively connecting it to a voltage source on the basis of a first control signal. The substrate includes, for at least one of the elementary light sources, an open-circuit fault detection circuit for detecting an open-circuit fault with the elementary light source.
