Description
The utility model belongs to lighting technical field, is a kind of energy-saving electronic ballast specifically.
At present, the following weak point of electric ballast ubiquity: 1, all use bidirectional trigger diode and capacitance resistance component to form in the sawtooth-wave circuit, the daylight filament is in non-preheating cold start-up like this, will urgent lamp tube ends turn black, though a lot of producers in the parallel connection of filament two ends diode, have little effect; 2, in circuit, only adopt the number of turn of adjusting base stage and emitter resistance resistance and oscillator coil, be difficult to make power tube to be operated in the optimized switch state; Discrete component is more in 3 circuits, so hazard rate is higher.
The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of energy-saving electronic ballast that adopts curing module IC1 and a small amount of peripheral electron element to form.
The utility model technical solution:
A kind of energy-saving electronic ballast is characterized in that 4,5 pin of curing module IC1 connect 220 volts of power supplys of civil power, and the base stage of BG1 connects the IC12 pin, and emitter connects the IC11 pin.Collector electrode connects the IC13 pin, connect the end a point of R1, C1 simultaneously, the base stage of BG2 connects the IC17 pin, emitter connects the IC16 pin, connects the end b point of R2, C2 simultaneously, and collector electrode connects the emitter of BG1, R1, C1, the other end of R2, C2 is connected in the C point respectively, and the C point inserts fluorescent tube W one pin again, and the IC18 pin inserts another pin of fluorescent tube W after inserting choke L.
Advantage of the present utility model:
The utility model adopts measures such as accelerating circuit, drive a back starter about 1 second of 20W-40W fluorescent tube preheating, the approximate saw of switching tube waveform shape ripple, power consumption is lower, and curing module IC1 integrates circuit such as ac-dc conversion, startup, anti-interference, acceleration.Have simple in structurely, failure rate is low, and starting resistor low (110 volts get final product starter) is compared with the iron-clad ballast, economize on electricity about 30%, and gastight bad pipe can continue advantages such as use.
Fig. 1 is the utility model electrical schematic diagram.
Below in conjunction with accompanying drawing the utility model is further described:
4,5 pin among the curing module TC1 feed 220 volts of alternating currents, C1, C2, R1, R2 form anti-jamming circuit, wherein, C1, C2 two ends are in parallel with R1, R2 respectively, and BG1, BG2, IC1 form the accelerated electron switching circuit, wherein BG1 collector electrode and C1, R1 1 end a point join, base stage and IC12 pin join, and emitter and IC11 pin join, and BG2 emitter and C2, R2 1 end b point join, base stage and IC17 pin join, and collector electrode and IC11 pin join.By the inner ac-dc conversion of IC1 etc., the rated voltage that anti-jamming circuit, accelerated electron switching circuit form is by the output of IC18 pin, and by choke L, it is luminous to drive fluorescent tube W.
