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

The ballast of the high-pressure gas discharge lamp, comprising: a DC power, a filter circuit, the flyback switch tube, DC - DC converter, a full bridge inverter, are connected to the lamp hot and cold state acquiring circuit of the controller, connected to the controlon the power supply circuit, a driving circuit and a sampling circuit, and an output terminal connected to the ignition circuit in the lamp. The full-bridge inverter input voltage DC power input voltage and DC - DC converter output capacitor voltage superposition. Controller controls the flyback switch on or off; tube control by controlling the flyback switching DC - DC converter power supply; circuit to obtain the bulb on the cold or hot state get through the bulb hot and cold state, to be able to issue the correct cold or hot startup mode; through the drive circuit, the full-bridge inverter control an ignition circuit connected to the lamp, i.e. the start-up and stabilization of the control lights.
