Abstract
The utility model discloses a ballast device. The device comprises a casing body, a coil, a first iron chip, a second iron chip, a trigger and a wiring row. The coil and the trigger are arranged in the casing body. The coil is connected with the trigger through a cable and the wiring row. According to the ballast device provided by the utility model, the coil is arranged to be far away from the trigger as much as possible, thus the safety of the ballast device is improved. At the same time, the ballast device provided by the utility model has the advantages of simple structure, small volume and strong practicality.
Description
Technical field
The utility model belongs to the electronic circuit technology field, relates to a kind of ballast, relates in particular to a kind of ballast device.
Background technology
Ballast is a gaseous discharge lamp indispensable matching component of when work, is used to provide instantaneous pressure and makes lamp lighting-up, and then ballast makes the stable work of fluorescent tube; Ballast is kept the voltage design for the high starting voltage and the low discharge of gaseous discharge lamp.
When applying the AC power of 220V 50Hz in the switch closure circuit, electric current flows through ballast, and the tube filament starter (breaks off when starter begins, owing to exerted pressure one greater than the alternating voltage more than the 190V to the filament heating; Make the jumping in the starter steep interior gas arc discharge, make bimetal leaf add thermal deformation, two electrodes are close together; Forming path heats to filament), when two electrodes of starter are close together, owing to there is not arc discharge; The bimetal leaf cooling, the two poles of the earth separate, because Inductive ballast is perception; When circuit interrupts suddenly, can produce the pulse voltage of the 600V-1500V of about 1ms of duration at the lamp two ends, its definite magnitude of voltage depends on the type of lamp; Under the situation of discharge, the voltage of lamp descends immediately, and this moment, ballast carried out restriction to lamp current on the one hand; Make on the other hand to produce 55 °-65 ° phase difference between the operating current of supply voltage and lamp, thereby keep the restarting voltage of lamp, make the work that lamp can be more stable.
Yet also there are some defectives in existing ballast, is still waiting to improve like its fail safe, and volume is bigger etc.
The utility model content
The utility model technical problem to be solved is: a kind of ballast device is provided, can solves the weak point of prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of ballast device, said device comprise housing, coil, first lamination, second lamination, trigger, line bank; Said coil, trigger are arranged in the housing, and said coil is connected with trigger through cable and line bank.
As a kind of preferred version of the utility model, said first lamination is connected with second lamination.
As a kind of preferred version of the utility model, said coil, trigger are arranged at the both sides of ballast device respectively.
The beneficial effect of the utility model is: the ballast device that the utility model proposes is provided with the fail safe that can improve ballast device as much as possible at a distance with coil and trigger; Simultaneously, the utility model ballast device is simple in structure, and advantages of small volume is practical.
Description of drawings
Fig. 1 is the structural representation of the utility model ballast device.
Fig. 2 is another structural representation of the utility model ballast device.
Embodiment
Specify the preferred embodiment of the utility model below in conjunction with accompanying drawing.
Embodiment one
See also Fig. 1, Fig. 2, the utility model has disclosed a kind of ballast device, and said device comprises housing (comprising base 1 and shell), coil 2, first lamination 3, second lamination 4, trigger 5, line bank 6; Said coil 2, trigger 5 are arranged in the housing, and said coil 2 is connected with trigger 5 through cable 7,8 and line bank 6.In order to improve the fail safe of ballast device, said coil 2, trigger 5 are arranged at the both sides of ballast device respectively, and distance is far away relatively.
In the present embodiment, as shown in Figure 1, said first lamination 3 is connected with the mode of second lamination 4 through argon welding 9.
In sum, the ballast device that the utility model proposes is provided with the fail safe that can improve ballast device as much as possible at a distance with coil and trigger; Simultaneously, the utility model ballast device is simple in structure, and advantages of small volume is practical.
Here description of the utility model and application is illustrative, is not to want the scope of the utility model is limited in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation of spirit that does not break away from the utility model or substantive characteristics, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change here to the embodiment that is disclosed.
