Double fluorescent lamp with glow starting device within the circuit and also the ballast series. Glow starting device is a glass bubble. Glass cannon using a U-shaped metal piece of glass tube filled with neon. Connect the energy when the neon glow discharge. To produce heat, double metal sheet is heated expansion. Double metal sheet and a different get in touch with. For the reason that when the make contact with resistance is extremely small. Neon glow discharge. The double metal sheet temperature decreased. Using the make contact with separation. Then the circuit disconnected. Ballast on account of inductance effect induced by higher voltage. In an effort to disconnect the radio equipment to create the electric magnetic interference within the glow starting device is connected in parallel having a capacitor.
When the lamp is bright, the interior is equivalent to a conductor, to ensure that the voltage across the fluorescent starter is not enough to emit a glow. Is equivalent to the lamp plus the ballast series connected inside the circuit, exactly where the ballast continues to play a restricted function, the standard operation with the circuit. As the electric power consumption in the old inductive ballast is as well significant and also the efficiency is as well low, it has steadily been replaced by the electronic ballast with higher efficiency. Electronic ballast for high frequency switch state, without the need of the ought to start start starter, luminescence in gas breakdown straight inside the tube, so power saving ballast: AC DC, DC variable AC – the frequency becomes greater. With all the public 50Hz will lead to the stroboscopic phenomenon, if it is actually 5000, the effect is not to really feel.
