Description
The present invention relates to a kind of circuit arrangement of controlling discharge lamp, especially low-pressure discharge lamp.
So-called control discharge lamp refers to all working state from the starter to the stabilized illumination.
Low-pressure discharge lamp, particularly fluorescent lamp are basically as electric lighting.Compare with incandescent lamp, they have higher light intensity, higher efficient and longer useful life.
Low-pressure discharge lamp comprises the lamp holder of discharge cell-shell (under the situation of fluorescent lamp, scribbling fluorescent material in it), electrode, gas filler and band contact plug in fact.Discharge lamp is luminous by the discharge process in its discharge cell-shell.
Low-pressure discharge lamp is negative because of its internal resistance, and can not directly link with electrical network.Thereby must between electrical network and discharge lamp, be connected to an auxiliary unit, with the starter and the work of this auxiliary unit regulation and control lamp.
Press the difference of the starter mode of lamp, various auxiliary unit can be provided.Wherein this class auxiliary unit of first preheating electrode is very general before gas discharge triggers.
Gas discharge triggers with potential pulse in the auxiliary unit of these types.This conventional auxiliary unit uses glow starter to produce potential pulse.Auxiliary unit now preferably only is made up of electronic component.This is specially adapted to miniature lamp, and auxiliary unit wherein is integrated in the lamp holder with as far as possible little space.Miniature lamp is compared with the fluorescent tube of routine, and its size is less.
The electronics auxiliary unit is known.They consist essentially of low pass filter, radio frequency rejects trap, rectifier and converter or frequency converter.This converter or frequency converter produce the high-frequency ac voltage of about 25-50KHz near the electrode of discharge lamp.When low-pressure discharge lamp when high-frequency alternating current is depressed work, produce higher light output when this lamp is worked than under low frequency.And by light that this job category produced also flicker free.
German patent DE-OS3840845A1 has described a kind of circuit arrangement of controlling low-pressure discharge lamp with the electric capacity of the inductance of discharge lamp series connection and relative discharge lamp parallel setting of using.One bipolar (twin-pole) in parallel with inductance wherein is provided, it is connected to the transfer point of load circuit on one side, and another side is connected to the positive pole of the direct voltage source of powering for circuit arrangement and/or is connected to its negative pole through a diode through a diode at least.These diodes make preheat circuit block after discharge lamp starts.At the ignition voltage (combustion voltage) of discharge lamp during greater than 70V, this is bipolar is made up of at the series circuit of two Zener diodes of relative direction a cold conductor (cold conductor) and electrode.This just prevents that at ignition voltage preheat circuit from blocking during greater than 70V.
U.S. Pat-PS4,647,820 disclose a kind of circuit arrangement of controlling discharge lamp, and it comprises the converter in order to the high-frequency work voltage that produces discharge lamp, the inductance of connect with discharge lamp, with the electric capacity of discharge lamp parallel installation and the cold conductor that is installed in parallel with electric capacity.There is such shortcoming in this known circuit arrangement, even thereby that is: still flow through the aging acceleration that cold conductor makes cold conductor at discharge lamp starter after-current.
During with this known circuit arrangement, the starting characteristic of discharge lamp is subjected to the restriction of the running parameter of ambient temperature and cold conductor, and this parameter is with changing service time.So use known circuit arrangement, discharge lamp can not have stable starting characteristic.
The present invention relates to such problem, the circuit arrangement of simple control a discharge lamp, particularly low-pressure discharge lamp promptly is provided, in order to control the discharge lamp that stable starting characteristic is arranged subtly.
According to the present invention, this problem is to solve like this: cold conductor is connected with two-way puncture voltage element connected in series, and be installed in parallel with inductance or electric capacity in the circuit arrangement, this circuit arrangement has high-frequency converter or frequency converter, the inductance that is connected in series with discharge lamp and the electric capacity of installing with discharge lamp parallel, and this cold conductor is in the same place by heat integration with two-way puncture voltage element.
Provide a kind of according to solution of the present invention in order to meticulous control discharge lamp, the simple circuit arrangement of low-pressure discharge lamp particularly, because the voltage limit that between the warming up period of lamp, produced, thereby prevented to increase the triggering certainly of the discharge lamp that causes because of the resonance of load circuit.
The thermal coupling meeting of cold conductor and two-way puncture voltage element makes cold conductor produce extra heating because of the thermal losses of two-way function puncture voltage element.This heat transfer effect by two-way puncture voltage element is to make with the variation of using the different cold conductor work parameters that cause with atmospheric temperature of the time limit starting characteristic of discharge lamp is only had very little influence, thereby guarantees that discharge lamp has constant starter characteristic.
Technical solution of the present invention is based on following information:
Inductance and capacitor form a series connection oscillating circuit.Electric current flows through cold conductor and two-way puncture voltage element between warming up period, thereby makes it heating.
Because cold conductor heating increases its resistance, so the voltage drop on the cold conductor is increasing, therefore this two-way puncture voltage elements act is to limit this voltage.And because cold conductor heating, the resonance in the series connection oscillating circuit that inductance and capacitor are formed increases and strengthens until the discharge lamp build-up of luminance.
In design of the present invention, the thermal coupling degree of cold conductor and two-way puncture voltage element can be set accurately.Thereby can accurately adjust the starting characteristic of discharge lamp.
At this two-way puncture voltage element of the lamp chien shih period of heating high output loss is arranged, this loss makes cold conductor produce special extra intensification by thermal coupling, and the corresponding resonance that sooner or later will cause in the oscillating circuit of connecting with the thermal coupling degree increases, and corresponding with the starter of discharge lamp.Just can accurately adjust by the thermal coupling degree of adjusting cold conductor and two-way puncture voltage element the starting characteristic of lamp.Particularly can pass through circuit arrangement of the present invention at an easy rate, make the different qualities value that adapts to lamp heating time.
Thermal coupling between cold conductor and the two-way puncture voltage element can be passed through intermediary's medium of being connected, carries out effectively such as viscose glue or paint etc.The thermal coupling degree especially can be adjusted by selecting to connect intermediary's medium accordingly.The adjustment of thermal coupling also can be undertaken by the space length that changes between cold conductor and the two-way puncture voltage element.
Penetrate diode (transildiode) or rheostat and can be used as two-way puncture voltage element.Anti-phase two Zener diodes that are connected in series of electrode also are applicable to and form two-way function puncture voltage element.
The puncture voltage of two-way puncture voltage element is preferably selected to such an extent that make it be lower than the starting voltage of lamp and is higher than the ignition voltage of lamp.Thereby between the warming up period of lamp, electric current flows through the preheat circuit of being made up of cold conductor and two-way puncture voltage element, thereby makes electrode obtain preheating when gas discharge is still unignited.
On the other hand, after causing gas discharge, promptly between the light emission period of lamp, no longer include electric current and flow through preheat circuit.At this moment, crest voltage is lower than puncture voltage.Two-way puncture voltage element opens circuit, and preheat circuit does not have additional load.
Preferably cold conductor and two-way puncture voltage sets of elements are formed in the construction unit.
The present invention will be described for embodiment below with reference to accompanying drawings.
Fig. 1 shows the circuit diagram of circuit arrangement of the present invention.
Rectifier 1, converter 2 and the load circuit 3 of the filter unit of band shown in the figure.This load circuit 3 comprises that inductance L 1, this inductance L 1 and the discharge lamp H1 that is connected in parallel with a capacitor C1 at least are connected in series.Cold conductor V1 and penetrate the same and capacitor C1 of the series circuit of diode V2 and be arranged in parallel.
Cold conductor V1 with penetrate diode V2 preferably by paint hot connection be in the same place, play the paint of hot coupling connection effect and represent with the dotted line of two elements in the drawings.Capacitor C2 plays the coupling and the level and smooth supply voltage of alternating current.
Converter 2 about 310V that feeds
SsSquare-wave voltage.When converter 2 started, electric current flow through heating winding, the cold conductor V1 of inductance L 1, lamp electrode and capacitor C1 in the load circuit 3 and penetrates diode V2.
Adjustment penetrates the puncture voltage of diode V2, so that discharge lamp H
1Can spontaneously not start, but the heating of having removed to guarantee electrode.Because cold conductor V1 and penetrate thermal coupling between the diode V2, thus make cold conductor V1 because of the thermal losses that penetrates diode V2 by extra heat temperature raising.Because of the cold conductor V1 intensification of being heated,, lighted the resonance of its resistance and the discharge lamp H1 that causes thus so increasing will increase until the latter.
When discharge lamp H1 was luminous, its crest voltage was lower than the puncture voltage that penetrates diode V2.Heater circuit is blocked, and does not use and can not produce transition.
