Abstract

The utility model discloses an electronic power saving device for replacing a starter and a ballast for fluorescent lamps. The electronic power saving device not only can be used as a momentary glow starting switch but also can save power for more than 38 percents after combined with a switch. The electronic power saving device uses diodes as a bridge rectifier circuit and capacitors as a filter circuit, an oscillating circuit, a glow starting circuit, etc. to finish glow starting work and the overall process of energy storing, boosting, igniting, dropping and current limiting work. Consequently the requirements of fast starting speed, stable work, no stroboflash, no noise and long service life are achieved. The multifunctional electronic power saving device for fluorescent lamps can ensure waste and old lamp tubes of no air leakage to recover illumination.

Description

The Multifunctional fluorescent tube Electronic energy saver

The utility model relates to the substitute products of switch, starter and the ballast of fluorescent lamp, specifically a kind of many merits fat fluorescent start, energy-saving appliance.

The existing bright and dark system of fluorescent lamp control that accounts for the market leading position is made of switch, starter and ballast three.Because starter and ballast must be installed near the fluorescent lamp, thus great inconvenience brought to maintain and replace, and the circuit more complicated is installed, it is also higher that the three lumps together price.In addition, this device is not suitable for the requirement of modern house finishing.

In order to address this problem, domestic have many inventors to apply for up to a hundred the relevant utility model patents that improve the fluorescent lamp control system, and what wherein belong to the electronic switch type also has tens.China Patent No.: 88220898; 89207994; 89220947; 89202313.9; 90205828 or the like all belong to the electronic switch type.These utility model patents all have common characteristic, have promptly replaced three kinds on original switch, starter, ballast with an electronic switch, and have also all used capacitor, diode or the like on its electronic structure.Though they on the volume, energy-conservation on, utilize on the useless fluorescent tube and all played certain effect, it is short that ubiquity service life, job insecurity and indivedual invention can't be used shortcomings such as single-way switch, so can't base oneself upon on competitive market.

The purpose of this utility model is will provide a kind of can save starter and ballast, no stroboscopic, noiseless, working stability, life-span are long, it can be suitable for domestic and international fluorescent tube conducting, useless fluorescent tube is recovered lost eyesight, and can work as the Electronic energy saver that switch can economize on electricity again.

The purpose of this utility model is achieved in that bridge rectifier and the filter circuit that setting is made of rectification crystal diode and electric capacity; Hit resistance, pulse transformer and electric capacity by NPN large power triode, base resistance, emission and constitute oscillating circuit; Constitute starting circuit by promoting transformer and electric capacity.After alternating current 220V is by commutation diode and capacitor filter, output 300V DC voltage, charge through resistance to electric capacity, the pulse transformer positive feedback effect vibrates triode, export and produce square wave, the square wave of output forms standard sine wave through series resonant circuit again, and produces high pressure, thereby makes tube starting shinny.

The utility model is because used high capacity capacitor and NPN large power triode, so can accomplish that starting speed is fast, working stability, simultaneously since fluorescent tube in start-up course, lamp tube ends has high voltage, therefore, gastight waste fluorescent lamp can generate electricity by laser too, and reaches specified illuminating effect.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the utility model particular circuit configurations figure.

The bridge rectifier and the filter circuit that constitute by rectification crystal diode D1, D2, D3, D4 and capacitor C 1 among the figure; By NPN large power triode BG1, BG2 and base resistance R7, R8, emitter resistance R2, R3 and pulse transformer L1, L2, L3 and capacitor C 3, C4 constitute oscillating circuit; Constituting starting circuit by lifting transformer L4 and capacitor C 6 forms.(1) is fluorescent tube among the figure.

Resistance R 4, R8 in the circuit, capacitor C 3, C4 constitute self-maintained circuit.C5 is a charge and discharge capacitance.Resistance R 1, R2, capacitor C 2 and diode D6 form saw-tooth wave generating circuit.Triode BG1, BG2 are electronic switch, end after the alternate conduction.

At first connect the 220V alternating current during work, during by the positive half cycle conducting of D1, D3, D2, D4 end, and when negative half period D2, D4 conducting, the round-robin method that D1, D3 end is removed output+300V DC voltage behind rectification and the C1 capacitor filtering, charge to C2 through R1, the C2 both end voltage is charged to C4 by R5, R7 again, just conducting of BG2 when C4 voltage reaches 0.7V, and this is by pulse transformer L1, L2, L3 positive feedback effect, triode BG1, BG2 are vibrated, and produce square wave output.Resistance R 2, R3 make current-limiting resistance after being connected on triode BG1 and BG2, the series resonant circuit that the square wave of transformer L3 output is formed by transformer L4 and capacitor C 6 forms standard sine wave, and on capacitor C 6, produce high pressure, thereby make fluorescent lamp (1) starter shinny.
