Rapid ballast for mechanical 40W FCL (annular fluorescent lamp)

摘要

In the ballast of the annular fluorescent lamp (FCL), the current is reversed by reversing the current direction of the primary coil and the secondary coil so as to minimize the power loss of the ballast itself, thereby increasing the efficiency. And the value of the capacitor (C) is 58.5 . The construction of the present invention relates to a mechanical type fastener ballast for an annular fluorescent lamp in which the primary coil (L1 And the capacitor C is connected via one end of the filament of the fluorescent lamp FCL and the secondary coil L2 is connected via the capacitor C. From the secondary coil L2 to the fluorescent lamp FCL ) Of the primary coil L1 and the secondary coil L2 are opposite to each other so that the power loss of the ballast itself is minimized to increase the efficiency of the ballast, The temperature rise of the capacitor is small and the possibility of burnout of the capacitor is low. It also has the advantage that a capacitor is damaged even by the current in the series resonance of the capacitor only car and to reduce the risk of fire, due to when assembling parts decreases and the work on the simple, can use a mechanical rapid ballast in an annular fluorescent lamp.
