Abstract
The utility model relates to a miniature electronic ballast energy economizer for fluorescent lamp. The miniature electronic ballast energy economizer for fluorescent lamp is used for the startup of fluorescent lamp. The utility model deals with the defects in the present starter for fluorescent lamp like high cost, high energy consumption, unable to startup in low voltage, short service life of lamp tube, etc. The utility model adopts a voltage boost circuit and an electronic ballast. The voltage boost circuit is composed of two capacitors (9) and (10) and two diodes (7) and (8). The utility model has the advantages of low cost, small size and long service life, and the miniature electronic ballast energy economizer for fluorescent lamp can be directly arranged in the ordinary fluorescent tube base. The miniature electronic ballast energy economizer for fluorescent lamp starts fast, has no flicker and saves power. The miniature electronic ballast energy economizer for fluorescent lamp can start up in the 160 V to 250 V voltages, and the lightness of the lamp tube can be regulated. The discarded lamp tube can also be used again.
Description
The utility model is a kind of fluorescent lamp ballast, particularly a kind of fluorescent lamp miniature electronic ballast energy-saving device.
Fluorescent lamp is widely used in illumination owing to luminous efficiency height, light are soft.At present, fluorescent start mostly adopts iron core ballast and starter start-up circuit, and one comes the cost height, and two come energy consumption also high, moreover, when voltage is low, just can't start, simultaneously, the two ends of fluorescent tube often are subjected to heavy current impact, turn black easily, so the useful life of fluorescent tube are not long.Other has a kind of resistance, capacitor start circuit, though cost is low, is easy to generate scintillation, has both influenced illumination, influences the useful life of fluorescent tube again.
Task of the present utility model provides a kind of booster circuit, is used to reduce the cost of fluorescent start device, reduces volume, saves energy consumption.
The utility model is achieved like this: two high-voltage diodes (7) and (8) are pressed the equidirectional series connection, also connect in two high pressure resistant capacitors (9) and (10), then, diode string and capacitor connection in series-parallel are got up, respectively connect at the two ends of this parallel circuits a current-limiting resistance (5) and (6), the two ends of this two resistance tap fluorescent tube, the phase line of 220 volts of AC power is from mid point (4) input of two capacitor connecting lines, and zero line connects the mid point (2) of two diode connecting lines.When alternating current when (4) and (2) are imported, charge immediately in capacitor (9) and (10), boost for twice through diode (7) and (8) again, in the negative terminal of diode (7), the pulse voltage of anode generation more than 1000 volts of (8), this pulse voltage adds to two ends (1) and (3) of fluorescent tube through current-limiting resistance (5) and (6), make fluorescent lamp moment startup.The size of the resistance value of the capacitance of regulating capacitor (9) and (10) and current-limiting resistance (5) and (6), the brightness of scalable fluorescent lamp.Current-limiting resistance (5) and (6) can be fixed resistances, also can be adjustable resistances.Capacitor (9) and (10) can be fixed capacities, also can be tunable capacitors.Electronic ballast energy-saving device of the present utility model can integratedly be installed in the daylight base, also can be installed in the mains switch.Also each element can be disperseed to install.
Fluorescent lamp miniature electronic ballast energy-saving device of the present utility model and other ballast starting drives have relatively that cost is low, volume is little, can directly put in the common daylight base, and be easy for installation; Under the situation that does not influence brightness, can economize on electricity more than 60%; But prolonging lamp tube service life also simultaneously, useless Guan Kezai usefulness, start fast, flicker free, when voltage is low to moderate 160 volts, high during to 250 volts, fluorescent tube can start in the same old way, and can keep stablizing of brightness.
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment: when 220 volts of alternating currents after the charging of electric capacity (9) and (10), boost for twice through diode (7) and (8) respectively, make the pulse voltages of anode output more than 1000 volts of the negative terminal of diode (7) and diode (8), make fluorescent lamp moment open bright.Metering function is played in resistance (5) and (6), to guarantee fluorescent lamp flicker free phenomenon.The brightness of all right determination date light modulation of resistance size of electric capacity and resistance.(2) connect the civil power zero line, (4) connect the civil power live wire, and (1) and (3) connects daylight lamp holder.Current-limiting resistance that adopts in the present embodiment and electric capacity all are fixed.
