Pipe in Pipe Electronic Ballast

Line Construction: TK01, 02 consisting of ballast and distribution in the tube ends. Tube in tube luminaries.
Circuit principle: 220V rectified by adding power factor correction circuit, inverter output, the direct use of high-voltage start lamp, no filament start capacitor.
Line features: the inductive heating device with the transistor two large separate, lower temperature rise, power factor up to 0.998, less than 10% of the current harmonics
Line advantages: high power factor, line stability.
Line defects: no filament current, cold start damage lamp large yellow circle and so prone to. Another direct use of shunt capacitors, line can not be empty, damaged lamp ballast will be damaged.
