Electronic adapter for fluorescent lamps/gas discharge lamps has transformer, supplied by electrical voltage supply and controlled to produce lamp operating voltage, and resonant circuit

摘要

The device has a transformer (2) supplied by an electrical voltage supply (1), a control unit (3) that controls the transformer to produce a lamp operating voltage and a resonant circuit (5) connected to the transformer output and to the lamp (6). The voltage supply or adapter has a (mains) rectifier or the voltage supply is a battery. Independent claims are also included for the following: a method of controlling a transformer with its output connected to a resonant circuit to which a fluorescent tube is connected.
