Abstract

The utility model relates to an electronic ballast for daylight lamps, which is provided with an impedance circuit composed of a filtering capacitor and nichrome wire resistors, and a multiple voltage rectification detection circuit composed of diodes and a capacitor. The utility model uses the multiple voltage rectification detection circuit to enhance the voltage in the circuit by more than 3 times to add to both ends of the daylight lamp so as to cause the start-up of the daylight lamp to be a cold start, lead filaments to be not easy to burn out, prolong the service life of the daylight lamp and compensate the power factors of the electric network. The utility model has the advantages of simple structure and low cost.

Description

Electronic ballast for fluorescent lamp
The utility model belongs to a kind of fluorescent lamp ballast.
Original fluorescent lamp ballast is actually an impedor, this ballast power consumption is big, heating is bigger, particularly can not the low voltage starting fluorescent lamp, and the fluorescent lamp stroboscopic is serious during use, influence people's eyesight, and use the fluorescent tube of this ballast short useful life.
The purpose of this utility model is to provide a kind of and adopts the toggle speed of many voltage multiplying rectifiers detecting circuit fast, power consumption is little, the electronic ballast for fluorescent lamp of no stroboscopic.
Major technique measure of the present utility model is as follows:
A kind of electronic ballast for fluorescent lamp has filter capacitor C 1, C 2, by the nickel filament resistance R 1, R 2Impedance circuit and the many voltage multiplying rectifiers detecting circuit formed, its many voltage multiplying rectifiers detecting circuit is by diode D 1-D 6, capacitor C 3-C 5Form diode D 5Anode and diode D 6Negative terminal join diode D 5Negative terminal and diode D 1Anode join diode D 1Negative terminal and diode D 2Anode and diode D 3Negative terminal join diode D 3Anode and diode D 4Negative terminal join capacitor C 1Be connected across diode D 1Anode and diode D 2Negative terminal between, capacitor C 2Be connected across diode D 5Negative terminal and diode D 6Anode between, capacitor C 3, C 4, C 5An end interconnect the composition common port, its other end respectively with diode D 2, D 3Common port, diode D 3, D 4Common port and diode D 4Anode join capacitor C 3, C 4, C 6Common port and diode D 1, D 5Common port be respectively two ac input ends of ballast, diode D 2Negative terminal and nickel filament resistance R 2An end join the nickel filament resistance R 2The other end join diode D as the positive output end of ballast and an end of fluorescent tube 6Anode and nickel filament resistance R 1An end join the nickel filament resistance R 1The other end join as the negative output terminal of ballast and the other end of fluorescent tube.
Operation principle of the present utility model is as follows:
When the ac input end lower end is timing, electric current is just through diode D 1, D 2With the nickel filament resistance R 2To the fluorescent lamp pipe, meanwhile to capacitor C 3Charging is flow through behind the fluorescent tube again through the nickel filament resistance R 1, diode D 6, D 4And capacitor C 4, C 5Form the loop to exchanging the input upper end; Be timing on ac input end, electric current is through capacitor C 3, C 4, C 5Charging, charging current is via diode D 4, D 3, D 2Many multiplication of voltages detecting circuit of forming is to the nickel filament resistance R 2Deliver to fluorescent tube, behind fluorescent tube again through the nickel filament resistance R 1, diode D 6, D 5Get back to negative terminal and form the loop.
Filter capacitor C in the circuit 1, C 2Can guarantee that fluorescent tube does not have stroboscopic, working stability; By the nickel filament resistance R 1, R 2The impedance circuit of forming can puncture fluorescent layer in the fluorescent tube fully by impedance operator and heat radiation, make fluorescent tube can reach normal brightness, but more than 3 times of this AC-input voltage of voltage that come out by the rectification of voltage multiplying rectifier detecting circuit, thereby under low-pressure state, also can reach the starter requirement of fluorescent tube.
Simple in structure, the dependable performance of the utility model can be good to electrical network redeeming while light characteristics, no stroboscopic.
