Description
The present invention relates to the electrical equipment of a kind of fluorescent light fittings and electronic clock combination.
In many families, need in a room, dispose fluorescent lamp simultaneously, wall-hanging electronic clock, ceiling fan etc., no matter light fixture is that messenger wire is installed or install on the suction top, the capital influences the succinct attractive in appearance of room space and is difficult to arrange, the fluorescent lamp that will have two lamp ballast devices combines with electronic clock, can overcome this defective.Clock body, fluorescent tube and lamp socket can be installed on the same basic component, and ballast etc. are installed in the back, can significantly reduce costs; But two fluorescent tube left and right symmetricallies are installed in the both sides of device or otherwise configuration, help the appearance design moulding of product, therefore, the scheme of fluorescent lamp of the present invention and electronic clock phase configuration also can be the double fluorescent lamp device of other form and combining of electronic clock.Because two lamps are tandem workings, it is good also to have the light quality, ignition device power factor height, advantage such as the ballast loss is little.
A kind of " dual-tube ballast " (seeing the GG87202669 that Chinese patent CN86202773 and its have improved) provides an a kind of ballast to light the scheme of two fluorescent tubes.Adopt the ballast of huge iron stamen to be actually the assembly of a reactor and filament transformer (filaments of preheating two lamp connection places), so its volume is bigger, and complex structure.Although adopted the magnetic shunt measure, the electromagnetic induction that is wound between the various coils on the same iron stamen can not be avoided fully, and the Filament Winding that connects two lamp connection places can not disconnect, and the electromotive force that the ballast winding produced when minimizing was started is unfavorable for lighting of fluorescent tube; During work, this place's filament is continued heating, will influence lamp tube service life and increase power loss.
Facts have proved that utilize the inductance capacitance series connection, this electric capacity still may be equivalent to be parallel to lamp tube ends in this circuit, (in fact the little electric capacity on the starter be exactly and in lamp tube ends) comes booster tension, though help the fluorescent tube starting point, if this capacitance is big, then volume is bigger; Requirement of withstand voltage is also high; Also will make lamp current wave deformation bad, and the light stroboscopic phenomenon be strengthened and the good advantage of due light quality when losing two-tube serial connection work, and influence lamp tube service life.
When two lamp series connection are used, because of the fluorescent tube characteristic variant, under the effect of alternating voltage, gas was at the degree varies sample of synchronization ionization in two lamps were managed before starting point, gas is lighted fluorescent tube and is brought difficulty in the high-tension electricity kinetic potential puncture pipe that ballast produces when giving starting, overcomes this not enough measure so will have.
Therefore, the filament that solves the two pipe connection places that exist when the string pipe uses can not automatic disconnection behind lamp tube starting, and before lighting, gas ionization is difficult in the pipe, is the key of this technology.
Ballasting circuit among the present invention can overcome above-mentioned deficiency.Its ballast volume is little and can be used for the occasion of single lamp; When lighting a lamp, power, have the function of automatic switchover alterating and direct current to electronic clock.
The circuit of dual fluorescent lamps of electronic clock devices is by the coil on the ballast (1,2,3,4) and constitute coil (7,8) on the bidirectional triode thyristor (5), resistance (6), microminiature transformer of controller (23), electric capacity (9), fluorescent lamp starter (10), fluorescent lamp (11,12), filament (13,14,15,16), rectifying pressurizer (17), diode (18,19), battery (20), electronic clock (21), electric capacity (22) is formed.
Accompanying drawing 1 is an electrical schematic diagram of the present invention.
Its course of work is as follows: before the each take-off of starter (10), adds to fluorescent tube (12) two ends, makes gas ionization in (12) pipe by electric capacity (9) alternating voltage, thus also ionization of gas in (11) pipe; The starter closure makes filament (15,16) preheating, and by filament (13,14) add to the T of bidirectional triode thyristor (5) at the voltage of coil (2) two ends generation this moment
1T
2Between the utmost point; Also pass through the primary coil (7) of microminiature transformer by the electric current of starter (10), the electric current that produces at secondary coil (8) makes (5) conducting, preheating (13,14), after the operate as normal, starter disconnects, coil (7) no current, (5) blocking-up, stop preheating (13,14), and coil (2) is series between two lamps, becomes the some of ballast coil.This can equivalence be to connect with fluorescent tube after coil (1) (2) series connection again.
When ballast only was used for two lamp, coil (3) can be cancelled or replace with a resistance.
When coil (1,2,3) series connection, be single lamp ballast.
Coil (4), rectifying pressurizer (17), diode (18,19), battery (20), electric capacity (22) is formed the alternating current-direct current auto switching electric source.When lighting a lamp, its VD is a little more than cell voltage behind rectifying and voltage-stabilizing for alternating current, and diode (19) conducting (18) is blocked, and electronic clock is by (17) power supply, and battery is not powered.Because the number of turn of (4) seldom, and the equivalent resistance of electronic clock is very big, the induced electromotive force influence that produces when ballast is started is minimum.When not lighting a lamp, (19) not conducting, battery is powered to electronic clock with the path disconnection of (17) and by (18), so can prolong the service time of battery.
The electric capacity (9) that is connected in parallel on fluorescent tube (11) two ends plays fluorescent tube ionization guiding, it is difficult to have solved fluorescent tube gas ionization in the pipe that causes because of characteristic difference when using of connecting, and needing the long starting time and the problem of number of times, its capacity is very little, can not influence the life-span of fluorescent tube.
Coil (2), the T of filament (13,14) and bidirectional triode thyristor (5)
1T
2The utmost point forms the preheating circuit of (13,14).In the present embodiment, the two ends of (2) are respectively by (13, the 14) T with (5)
1T
2The utmost point links.Like this, be the preheating winding of filament during (2) starting, during work the ballast winding.This filament starting back, place no current, thus the energy prolonging lamp tube service life is arranged, short, power consumptive province of starting time, the ballast volume is little, and is simple in structure, T
1T
2Advantages such as the voltage between the utmost point is low.
The microminiature transformer, bidirectional triode thyristor (5), resistance (6) can be installed in the aluminum hull (starter shell), constitutes controller (23).Resistance (6) mainly is the conducting electric current that is used for adjusting (5), with the control loop of coil (8) composition (5).。This loop is by microminiature transformer and isolated from power, T
1T
2Voltage between the utmost point has only tens volts, so that bidirectional triode thyristor extremely is difficult for is destroyed; (5) be subjected to the control of the starter (10) of connecting with primary coil (7), break-make is reliable.So the reliability of device is very high.
Ballasting circuit of the present invention partly is suitable for pre-heated lighting installation of double fluorescent lamp, but the unsuitable beyond supply voltage of the voltage after the fluorescent tube series connection 65%, and should be according to the parameter designing ballast of fluorescent tube, controller removes to be adjusted the resistance (6), gets final product supporting use.The device that constitutes has that ballast is in light weight, volume is little, simple in structure, light quality good, power saving, the reliability advantages of higher.The low temperature of fluorescent tube, the starting performance of low pressure, life-span all can reach the level of same fluorescent tube when single tube uses.
Accompanying drawing (2) has described that this product is partly constructed and embodiment of profile.Some decorative positions and part do not omit and draw.Fluorescent tube is also symmetry installation in the clock both sides, and such essential structure is in order to save material and to be convenient to the fluorescent tube configuration of length of less Zhong Nengyu.Fluorescent tube and electronic clock and ballast etc. are installed in the moulding of usefulness flame retardant plastics, and have on the framework (25) of bonnet function, and ballast is installed in its back upper place, and should have with a certain distance from device, and the positive light of framework is decorated, and can be the combination of several parts.
