Abstract: A device for optimized management of fluorescent lamps with a control module having microprocessors with a control program in permanent memory (EPROM, PROM or equivalent); an internal control program, stored in the memory; and an electronic power module for direct power supply of lamps to change the voltage at the output within a range between a maximum power supply voltage and a lower appropriate voltage, at the command of the control module. The memory has at least some of the following accessories: A/D converters; an internal "real time" clock; an RS232 or RS422 asynchronous or synchronous serial interface; EAROM, EEPROM memory; a keyboard with LCD or LED display; control pushbuttons and indicator lights; and analog sensors for ac voltage, ambient light, external light, ambient temperature, power module temperature, and alternating current, the number and type of sensors being dependent on the selected configuration which in turn depends on user requirements.
