Description
Technical field
The present invention relates to ballast technical fields, specifically, are related to a kind of ballast for lamp.
Background technology
Ballast is the equipment that metering function is played on fluorescent lamp and generates instantaneous pressure, it is on the iron core made in silicon steel
Twine enameled wire to be made, the coil of such ribbon core, when moment, ON/OFF powered on, will self-induction generate high pressure, be added in day
On the electrode (filament) at the both ends of light lamp tube.This action be alternately, when starter (jump bubble) is closed, the lamp of fluorescent tube
Silk is turned on by ballast current limliting to generate heat；When starter is opened a way, ballast will self-induction generate high pressure and be added in the both ends of fluorescent tube
On filament, the phosphor powder of filament launching electronics bombardment tube wall shines, and starter is repeated several times break-make, will be repeated several times such
Action, so as to get through fluorescent tube.When fluorescent tube normal luminous, internal resistance becomes smaller, and starter just remains open-circuit condition, such electric current
It is worked with regard to stable by fluorescent tube, ballast, makes fluorescent tube normal luminous.Since ballast is when fluorescent lamp works, have always
Electric current is by that so easily generating vibration, and can generate heat, so there is the fluorescent lamp of ballast, be particularly ballast quality not
When good, very big sound can be generated, the time is grown, and is also easy to burn.Existing ballast is to be fixedly installed in lamp body
Inside, this brings great inconvenience for the replacement of ballast.
The content of the invention
Present disclosure is to provide a kind of ballast for lamp, can overcome certain or some defects of the prior art.
