Circuit for igniting fluorescent lamp

  title={Circuit for igniting fluorescent lamp},
The circuit is employed for advertizement displaying device, and reduces energy consumption. The circuit includes a 1st resonance circuit which has a 1st condenser, a 1st inductor, a 2nd condenser, a 1st switch, and a DC source, a 2nd resonance circuit which has a 2nd switch, a 3rd condenser, and a DC source, and a switch control circuit which alternatively operates 1st and 2nd switches. The 1st and 2nd switch circuits have 1st FET and 2nd FET. The 3rd switch has three contactors; the 1st… CONTINUE READING
