Description
Technical field
The present invention relates to the circuit arrangement for ignition of high-intensity discharge lamp.Generally speaking this circuit structure is made of the ballast that is used for the EID lamp.This circuit structure also can be made of the exciter that separates.
Background technology
The HID lamp typically refers to a class lamp that comprises high-pressure mercury-vapor lamp, high-pressure sodium lamp, metal halide lamp and low-pressure sodium lamp.The HID lamp has glow mode at its duration of exciting, under this pattern, complete arc discharge occurs and produces the aura generating in the lamp before.For providing the ballast of the routine of electric energy, the HID lamp comprises an exciter.This exciter provides the high pressure that is applied on lamp excitation pulse, so that lamp is started working.
Before lamp entered its glow mode, the energy of the high-voltage pulse that will be produced by exciter offered lamp.When lamp begins to enter its glow mode, cut off exciter.During glow mode, do not produce high-voltage pulse.When successfully having carried out exciting, lamp enters stable state rapidly by glow mode, promptly enters arc discharge state between the lamp electrode from glow discharge.Successfully excite required energy value to depend on that many factors and institute's energy requirement change, these factors for example are the local pressures of the gas in (but being not limited to) lamp.So that the energy of exciter lamp is when not enough, lamp will be trapped in its glow mode when sending into the HID lamp, and can not arrive a stable status (arc discharge fully).
Be in the electrode that glow mode can damage the HID lamp repeatedly for a long time, lamp is damaged.
Summary of the invention
Therefore, be desirable to provide a kind of improved HID exciter of HID exciting characteristic reliably that has.Specifically, this exciter should be avoided the long glow mode time.

Other purpose of the present invention and advantage are seen from this specification with will be apparent from.
Therefore, the present invention includes relevant several steps, embody the parts of architectural feature, be used for realizing the element of these steps and the combination of part, all is exemplary in following detailed announcement, and scope of the present invention will indicate in claims.
Description of drawings
Fig. 1 is the schematic diagram according to circuit arrangement for ignition of the present invention.
Embodiment
In order more fully to understand the present invention, following description will be carried out in conjunction with the accompanying drawings, and this figure is a circuit structure of the present invention.As shown in the figure, this circuit structure comprises ballast 10, and it links to each other with AC power 20 with 36 by a pair of input 33.Ballast 10 provides electric energy by pair of output 39 and 42 to HID lamp 40.
Ballast 10 comprises an autotransformer 60, and this transformer has the former limit winding 60 of band tap 63.Winding 60 links to each other with 36 with input 33.Capacitor 66 is connected between the end of tap 63 and ballast winding 65.Comprise first tap 76 and second tap 77 with former limit winding 60 magnetic-coupled ballast windings 65.The part of the ballast winding 65 between the tap 76 and 77 is called exciter winding 79 usually.The other end of ballast winding 65 links to each other with output 39.
The effect of ballast winding 65 is electric currents of restriction/control flowing through lamps 40 when lamp 40 is lighted.SIDAC 89 links to each other with 77 with tap 76 respectively with capacitor 92.SIDAC 89 and capacitor 92 also the tandem compound by inductor 95 and resistor 96 with former limit winding 60, input 36 and the node that output 42 connects together are linked to each other.Exciter winding 79, SIDAC 89, capacitor 92, inductor 95 and resistor 96 constitute an exciter (being start-up circuit) 80 together.Exciter 80 can integrally be linked on the ballast winding 79.In addition, SIDAC 89 can distinguish removably with capacitor 92 and links to each other with 77 with tap 76.
The course of work of ballast 10 is as follows.Electric energy is applied to the input 33 and 36 of ballast 10 from AC power 20.The voltage that AC power 20 produces is not enough to exciting/start lamp 40, and exciter lamp 40 need excite (startup) pulse.Excitation pulse is provided by exciter 80.More particularly, when electric current was flowed through capacitor 92, inductor 95 and resistor 96, capacitor 92 was charged to the puncture voltage of SIDAC 89.
Select puncture voltage, so that, in other words, equal or just be lower than the glow discharge voltage of lamp 40 corresponding to the characteristic glow discharge voltage of lamp 40, but far above the voltage of the stable arc of lamp.The glow discharge voltage of dissimilar HID lamps is different, and whether this electrode that depends on lamp has emitter.Electrode is had the lamp of emitter, and glow discharge voltage is markedly inferior to the glow discharge voltage that electrode does not have the comparable lamp of emitter.For one of ordinary skill in the art, the glow discharge voltage of lamp can be determined by experiment at an easy rate.In other words, puncture voltage is that the voltage at lamp two ends when approximately finishing according to the lamp glow mode is selected.
In case reach puncture voltage, SIDAC 89 switches to conducting state from previous cut-off state.Capacitor 92 by exciter winding 79 and SIDAC 89 discharges, makes to produce pulse voltage at the two ends of exciter winding 79 now.By the effect (being that ballast 65 is as autotransformer) of transformer, produce high-voltage pulse at the two ends of output 39,42.Capacitor 92 periodically charges and discharges, and produces a series of high-voltage pulses at the two ends of output 39,42.By the puncture voltage of SIDAC 89 and the glow mode of lamp 40 are interrelated, before the glow mode of lamp 40, provide excitation pulse with basic overall process at glow mode by exciter 80.In transition period from glow discharge to complete arc discharge, the voltage at lamp 40 two ends temporarily increases.Carry out the transition to after the complete conditions at the arc (discharge), the voltage at lamp 40 two ends fully descends, and SIDAC 89 is ended.Therefore, carry out the transition to after the complete arc discharge, cut off exciter 80.
SIDAC 89 detects the output 39 of ballast 10 and 42 voltage as voltage detector.Periodically conducting and by responding of 80 couples of SIDAC 89 of exciter provides enough energy that lamp 40 is switched.Specifically, before glow mode and at least the overall process at basic glow mode produces excitation pulse continuously, has avoided lamp 40 to be trapped in glow mode after for a long time.Substantially eliminated be trapped in glow mode for a long time and cause to the damage of lamp electrode and then to the damage of lamp.
For example, when lamp 40 was metal halide lamp, nominal value was 150 watts usually, and 95 volts, the puncture voltage of SIDAC 89 is between approximately 110-125 lies prostrate, and approximately the pulse voltage between the 110-125 volt is applied to exciter winding 79 two ends.In order to start lamp, formed the voltage of about 1800-3500 volt at the two ends of output 39,42.Approximately the puncture voltage of the SIDAC of 110-125 volt corresponds respectively to the modulating voltage between the 150-200 volt.Before the glow mode of lamp 40 and at least in the overall process of basic glow mode, repeat charging process to capacitor 92, cause producing the puncture voltage of the SIDAC 89 that is applied to the high-voltage pulse on the lamp 40 up to arrival.When finishing, glow mode cuts off exciter 80.
More particularly, in case lamp is lighted, the voltage at SIDAC 89 two ends just drops to it below puncture voltage.Exciter 80 no longer can produce pulse voltage at the two ends of exciter winding 79.In other words, as long as lamp 40 keeps lighting, exciter 80 just can not produce other pulse voltage.
According to a preferred embodiment of the invention, ballast 30 is metal halide lamp constant wattage autotransformers (CWA) of 150 watts, and it can be from Advance Transformer Company of Rosemont, and Illinois obtains, and Part No. is 71A5486.The nominal value of capacitor 66 is 22.5 microfarads, 240 volts.SIDAC 89 can be from Shindengen Electric Mfg.Co., and Ltd. obtains, and Part No. is K1V12, and nominal breakdown voltage approximately is the 110-125 volt.The nominal value of capacitor 92 is about 0.33 microfarads.Lamp 40 is high-intensity discharge lamps, and for example (but being not limited to) is 150 watts 95 volts metal halide lamp.Inductor 96 generally comprises the coil of two series connection, and the nominal value of each coil is 22 milihenries.The nominal value of resistor 95 is 3.5 kilo-ohms.
Can understand at an easy rate now, the invention provides a kind of improved mode of excitation, wherein before the glow mode of lamp 40 and at least in the overall process generation excitation pulse of glow mode substantially.By being provided for successfully starting enough energy of lamp 40, having avoided lamp to cross and be stranded in glow mode longways.
Can see that the purpose of the invention described above becomes very clear by above description, under the premise of without departing from the spirit of the present invention, can do various modifications.Included all the elements and content shown in the drawings all should regard illustrative as in describing above, rather than restrictive.
