Abstract

The device comprises a switchable electrical power unit (3) whose output voltage is regulated by a regulator (4) which receives a setpoint value delivered from a detector (5, 6) of ambient luminosity, and a real value delivered by a detector (7) of the luminosity of the said light source (1). The invention applies in particular to signalling or display devices. <IMAGE>
