Lighting Control Systems

Used for streets and tunnels control of lighting systems to ensure the best power saving while keeping the compliance according to the European & international standards.

The energy consumption in the lighting sector, whether in public lighting or private users, constitutes a high percentage of the total energy used.

Energy saving and light pollution are two currently much discussed topics involving all the operators in the lighting field to such an extent as to become the object of national and international recommendations and directives.

UNI standard 10819 sets down clear indications on the creation of lighting plants with particular guidelines for cutting down maintenance costs, reducing energy consumption, and limiting the flow of light dispersed upwards at desired times.

In connection with this, many governments have taken steps with promotional campaigns and subsidies to provide incentives for using high efficiency lighting sources and equipment suitable to curb energy consumption.

The statutory provisions in force therefore encourage the birth of new technologies that permit to reach these aims by acting on voltage stabilization and regulation.

The luminous flux regulator system starts up by automatically executing the ignition cycle of the lamps in a time programmable by the user depending on the type of lighting source powered (the ignition voltage and cycle time is user programmable).

After this, the regulator gradually reaches the preset rated voltage value. When, for various reasons, the peak lighting level is no longer needed, the regulator reduces the voltage powering the lamps, thus achieving a significant energy saving.

The transitions between the various operating conditions are so slow that the change in illumination is not perceptible to users.

Whatever the operating conditions, the output voltage is maintained within ±1% of the preset value, even with considerable input voltage variations.

After a black-out, when the mains is restored, the system performs a new ignition cycle before bringing the output voltage back to the preset value. This function is essential to grant a safe restrike of the lamps.
