the creation of dangerous dark areas, caused by the lamps that are kept off, in order to save energy. The stabilization and the regulation of the voltage combined with the possibility to program the switching-up and the power reduction cycles according to the different installations, assure the correct powering of every kind of light installation. The microprocessor based control unit allows the gradual variation of the voltage and permits a custom use of lighting systems. The system can be programmed: • directly using the keyboard; • with remote management system. It's possible to control the installation by using a light sensor to obtain a lighting flux in relation to day-light intensity level. For example at the entrance or at the exit of tunnels it becomes a necessity to regulate the level of light of the lamps according to the outside light intensity avoiding in that way dangerous dazzlings. This system has a large range of applications, it is extremely flexible an suitable both for simple plants and sophisticated installation connected to a remote control system. he lighting flux regulator "ELIGHT" series is a power supply system for lighting installations which permits the control and the regulation of the power rates in lighting system. In order to optimise costs and performances daily energy. The main advantage is an uniform level of light, by avoiding TABLE: SAVING ON DIFFERENT KIND OF LAMPS (IN PERCENT) MINIMUN VOLTAGE VALUES IN REDUCED RATE ENERGY SAVING INCANDESCENT HALOGEN INCANDESCENT MERCURY H.P. SODIUM H.P. SODIUM WITH HG BALLAST SODIUM LOW PRESSURE METAL HALIDE Lamp without anti-turnig off Lamp with anti-turning off

EDUCING OF THE MANAGEMENT COSTS PERATING CYCLE Using the flux regulator, the duration of the lamps is more than doubled. Several tests have been conducted on different installations and the average life of lamps is resulted to be 16/18000 hours. We will have: Stabilization at standard rate Rising slope Rising slope Stabilization at reduced rate Falling slope Stabilization at standard rate Power on: Stabilization at partial reduced rate Rising slope DIAGRAM OF THE OPERATING CYCLE Stabilization at reduced rate • Reduction of the costs for maintenance more than 50% thank to the extended life...

The internal timer allows the programming of 4 different cycles of reduction during the 24h, is also present a device that automatically by-pass the regulator in case of irregular operation. The RACK is connected to the system by means of pull out connectors to allow the complete removing without disconnecting the screwed connections. he microprocessor electronic control is made on a standard RACK container with 4 electronic board in EURO standard and connected to the system by means of a pcb and plug connectors on the back side of the container. The four pull-out boards have the following...

he microprocessor electronic control is made on a standard RACK container with 4 electronic board in EURO standard and connected to the system by means of a pcb and plug connectors on the back side of the container. The four pull-out boards have the following functions: he "ELIGHT" flux regulator, besides the standard mode, can have advanced functions in advanced mode "ELIGHT PLUS". In this case the regulator has the possibility to manage the lighting installation with different communication systems: on site using the keypad; or with a remote control (via radio or over the telephone...

Installation on all existing systems uceconomy is able to complete every single pre-existing installation using all kind of lamps. Reducing of energy consumptions uceconomy allows the timing and the operating mode of the lighting system to be programmed, hence allowing to operate at nominal values when it is required and to be driven at a "reduced rate" at other times. This causes an estimated saving in energy consumption up to 50%. Remote control and remote monitoring he connection between the remote control/monitoring station is through telephone line, optical fibres or via radio modem....
