China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Long life of fluorescent electronic ballast, which is solved in the prior art, electronic ballast fluorescent lamp is started, the filament preheat can cause fluorescent loss, reducing the service life fluorescent lamps and fluorescent filament loop can not be disconnected after start consumption of technical problems, the present invention employs the technical solution is longevity in an energy-saving fluorescent lamps between the filament and the pin in position near the filament has a series or two pins at one end of the filament connected in parallel between the heat sensitive switch. The structure of the electronic ballast circuit, comprising: an electronic ballast, the electronic ballast connected to the output of fluorescent lamps and two supporting resonant capacitor, the fluorescent lamp used in series in the circuit of the present invention, the thermal switch longevity energy-saving fluorescent, matching the resonant electronic ballast capacitor in parallel with two outputs, starter capacitor connected in series to the thermal switch fluorescent outer pin and the other end of the filament pins. The beneficial effects of the present invention is the longevity of energy-saving fluorescent simple structure, low cost, low consumption fluorescent lamps, long life and use to reduce reactive loss.
