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

Fluorescent lamp starter and ballasts, the current principle, the role of power connected, 220V AC ballast, ballast mutual inductance of about 600V high voltage is applied to the lamp.Lamp reflect, but parallel to the starter on the other side of the bulb, 600V high voltage through the filament, and added at both ends of the starter  inside neon bulb can not afford to 600Vhypertension, breakdown neon neon gas inside the bulb, emits red, and issued a thermal contact heat, neon bulb, the role of the heat, the body Fair and encounter another contact, the contactin this case, the neon bulb is shorted state, after a short circuit, the filament of the lamp under the action of short circuit, is energized, the light emitting, fever. Neon bulb short circuit across the neon bulb is not electric, and soon, neon bulb hot Minsi cooling and contraction, contacts open. Minsi's hot in in not within starter neon bulb disconnect across the lamp filament is not voltage stop to shine, but not the mercury vapor lamp is not cool in starteri off open the same time, the mercury vapor in the lamp was of the effect of the heat, and 600V hypertension conduction emitting light. The voltage across the lamp after emitting accumulation decreased down to about 110V. Lamp 110V AC supply, stable work, starter voltage drops below 110V internal neon bulbs can not be turned on light-emitting so electronic starter not action.
