Below we present the control systems available with our products, systems ranging from the management of a few lighting points to entire industries and cities.

Virtual midnight

It’s an automatic system, completely integrated in the light fixtures that does not require any additional wiring or external hardware.

Designed to reduce the luminous flux according to a preset program with a maximum of 5 phases (time bands) per operation cycle, each one customizable with a different level of reduction as shown in the image on the side.

For the first 3 days after installation, the lamps will operate at full power, acquiring ignition times, and then begin to reduce power from the fourth day. Operation is based on the calculation of a virtual midnight (mid-ignition point) which is used as a midnight reference for the programmed reduction scenario.

The virtual midnight calculation is automatic and continuously updated throughout the year.

The system is particularly used for street and parking lot lighting.

1-10V / DALI

They are lighting cable control systems, both require the installation of 2 additional poles for operation in addition to the power supply.

1-10V is an analog control, based on the distribution of a voltage signal between 1 and 10V, where 1V corresponds to 10% luminous intensity and 10V corresponds to 100% luminous intensity.

One or more lamps can be controlled by an illuminance or presence sensor using this communication line.

When wiring, it is mandatory to respect the polarity of the 2 dimming cables, especially if control units are present.

DALI is a digital control, where each lamp is assigned a unique address, which allows the control of the individual light points and communication with the lamps to verify their correct operation.

DALI allows the creation of control groups and the interface with presence and luminance sensors for the control of entire production and local lines.

Lineswitch

Lineswitch is an economical, versatile and immediately integrated dimming system with existing systems with third or fourth control wire, in which a 230V (phase) voltage signal is distributed and when activated reduces the power to the required level. In case of new systems, it requires the installation of an additional pole in addition to the power supply ones.

The signal can be controlled by timers, presence sensors or other types of sources.

A single reduction level can be programmed, which can be modified in the switching times using the external controllers but cannot be modified in the field in terms of intensity.

The possible applications vary according to the type of sensor adopted, ranging from street lighting, petrol stations, car parks and industrial perimeter areas.

Presence and illuminance sensors

It’s an automatic system, completely integrated in the light fixtures that does not require any additional wiring or external hardware.

Designed to reduce the luminous flux according to a preset program with a maximum of 5 phases (time bands) per operation cycle, each one customizable with a different level of reduction as shown in the image on the side.

For the first 3 days after installation, the lamps will operate at full power, acquiring ignition times, and then begin to reduce power from the fourth day. Operation is based on the calculation of a virtual midnight (mid-ignition point) which is used as a midnight reference for the programmed reduction scenario.

The virtual midnight calculation is automatic and continuously updated throughout the year.

The system is particularly used for street and parking lot lighting.

Wireless Remote Control

Our street lamps are available with a wireless remote control system to manage dimming functions, consumption monitoring (statistical development) and faults.

The light intensity control can be carried out individually or divided into control groups, either by acting manually on the lamps or by customizing up to 6 fully automatic programs.

The control platform is exclusively online and can also be controlled by mobile devices, equipped with a standard Google Maps application for immediate location of the lamp / control group.

Communication between terminal and coordinator is totally secure and encrypted via https protocol.

The system consists of:

  • A coordinator, responsible for the exchange of information with the lamps (dimming commands and operating status), who must be connected to the internet. Available in economy version with Ethernet connection or in GPRS 3G version using the mobile network. Each coordinator can control up to 150 lamps and the maximum distance reachable in open field with the first lamp is 50 m.
  • Radio controllers mounted inside each lamp, operating at 868MHz. For better reliability of operation and operating distance, the lamps create a mesh communication network, replicating in turn the signal sent by the coordinator. It is not necessary for all lamps to be mounted within the coordinator's field.

The system is used for street lighting, large car parks and control of tunnel entrances.

Zigbee

It’s an automatic system, completely integrated in the light fixtures that does not require any additional wiring or external hardware.

Designed to reduce the luminous flux according to a preset program with a maximum of 5 phases (time bands) per operation cycle, each one customizable with a different level of reduction as shown in the image on the side.

For the first 3 days after installation, the lamps will operate at full power, acquiring ignition times, and then begin to reduce power from the fourth day. Operation is based on the calculation of a virtual midnight (mid-ignition point) which is used as a midnight reference for the programmed reduction scenario.

The virtual midnight calculation is automatic and continuously updated throughout the year.

The system is particularly used for street and parking lot lighting.

Power-line communication

It is a lamp management system that uses existing power supply cables.

Pulses are sent through the cables at frequencies much higher than the normal 50/60Hz frequency which are interpreted by the control units inside the individual light points as commands to vary the luminous flux.

The system can be used with all our road and tunnel luminaires.

Luminance probe

Our wireless remote control system and the conveyed waves, for the management of the tunnel entrances, communicate with a luminance probe mounted outside that detects in real time the level of natural light, adjusting the intensity of the lamps to avoid the black hole effect and glare.

Tunnel lighting

The main statistics show that tunnels are overall less prone to accidents than the corresponding open-cast sections. This is due to the fact that traffic in tunnels is not exposed to meteorological factors, intersections, mutual glare and pedestrian conflict.

Entry and exit areas, if not properly lit, can become dangerous traps for road users.

Glare and black hole effect can make the driver completely unable to see a column of vehicles queuing up or other obstacles, preventing them from reacting in time. Luminance, illuminance and uniformity levels are set by regulations according to traffic characteristics, road condition and speed.

The representation to the side shows the arrangement of the luminaires according to the different luminance levels required in the gallery areas.

Reinforcement lighting should be controlled throughout the day to make entering and exiting the gallery as safe as possible. At night, the reinforcement system is switched off and the permanent system dimmed according to the characteristics of the tunnel.

The best control can be achieved by adjusting the portals with luminance probes, for instant power adjustment according to the external light level.
