The present invention relates to a fluorescent lamp seat, and more particularly to a fluorescent tube electronic rectifier.
Nowadays, the traditional fluorescent lamp tube electronic rectifier makes use of an inverter circuit A to light the fluorescent lamp by producing high-frequency and high-voltage at the two ends of a fluorescent tube B (as shown in
In order to overcome the above-mentioned problems, the objective of present invention is to provide new type of fluorescent tube electronic rectifier.
For achieving this objective, the present invention provides a fluorescent tube electronic rectifier which includes an inverter circuit and an inductance rectifier; one side of the fluorescent tube is to connected to the output end of the inverter circuit and the other end of it is to connected to the output end of the output end of the inductance rectifier. Both of the inverter circuit and the inductance rectifier have an input end to be connected to a suitable current source.
The following advantages can thus be attained: 1. By connecting one side of the fluorescent tube to the inverter circuit to produce high frequency and high voltage and the other side to the inductance rectifier to produce power frequency voltage, the peak value of the current of the fluorescent tube is less than 1.7 to avoid the darkness at the two end of the light tube and lengthen its the service life; the problem of early darkness of the traditional electronic rectifier can thus be solved. 2. The combination of the inductance and the electron can provide a higher stability, lower content of resonance and better ability of anti-jam.
As shown in
In each of the attached figures, L1 is a inductance rectifier, D1-D9 are diodes, C2-C8 are capacitances, R1-R6 are electric resistances, while triodes BG1 and BG2, inductance L2, N1, N2 and P combined to form a inverter circuit (1) and capacitances C7, C8 and inductance L2 create jointly a LC resonance oscillation to produce high frequency and high voltage.
