Abstract:
An electric gas-lighter, comprisinga discharge generating circuit (45) having input terminals (41, 42) connectable to a supply source (43) and at least one output terminal (3) for generating sparks; and a filter (70) for filtering electromagnetic noise; wherein said filter (70) consists essentially of a single capacitor (71) having a first terminal communicating with a reference potential (73), and a second terminal communicating with one (42) of said input terminals (41, 42) via a first resistor (65); and wherein said discharge generating circuit comprises a transformer having a primary winding and at least one secondary winding communicating with said output terminal; a main capacitor having third and fourth terminals connected to said input terminals, respectively, via a rectifying circuit; and a discharging circuit connected to said main capacitor to discharge the current accumulated in said main capacitor into the primary winding of said transformer.
