Abstract

The circuit for emitting optical signals adapted to the ambient light consists of a transformer (XFMR) connected on the primary side to an a.c. input (INP) and on the secondary side via a rectifier circuit (GS) to the input of at least one lighting unit (BE1) fitted with electroluminescent diodes (LD1, ..., LDx). The circuit is compatible with circuits using incandescent lamps, but has a much lower error probability.
