Abstract

THE INVENTION RELATES TO A CIRCUIT ASSEMBLY FOR OPERATING AN ILLUMINATED SIGN, IN PARTICULARLY AN LED SIGNAL, HAVING AT LEAST ONE LIGHT-EMITTING DIODE (D), WITH WHICH A RESISTANCE (R) IS CONNECTED IN SERIES AND A CONTROLLER (ST) IS CONNECTED IN PARALLEL. IN ORDER TO MATCH THE LIGHT POWER OF THE ILLUMINATED SIGNAL TO DIFFERENT ENVIROMENTAL BRIGHTNESS DURING THE DAY AND NIGHT, THE INVENTION PROVIDES FOR THE CONTROLLER (ST) TO HAVE A CONTROLLED CURRENT SOURCE FOR PRESETTING A PARALLEL CODE (I_P) WHICH REDUCES THE CURRENT (I_D) FLOWING THROUGH THE LIGHT-EMITTING DIODE (D).
