Description
Technical field
The utility model belongs to electronics and lighting energy saving technical field, relates to a kind of fluorescent lamp low-light illumination auxiliary device.
Background technology
Conventional inductance type fluorescent lamp, when connecting 220V AC power, electric current flows through inductance type ballast, disconnect when starting to the starter of filament of fluorescent lamp heating, due to the alternating voltage being greater than 190V of having exerted pressure, make the gas arc discharge in starter, make bimetal leaf heat distortion in starter, make two electrode contact conductings, form path to filament of fluorescent lamp electrified regulation, when after the electrode contact of two in starter, arc discharge stops immediately, bimetal leaf cools rapidly, and two electrodes disconnect immediately.Because inductance type ballast is perceptual device, when the unexpected power-off of inductance type ballast, produce the high voltage pulse of about 900 ~ 1100V in fluorescent lamp two ends self-induction, in the case of a discharge, fluorescent lamp both end voltage can decline immediately, and now inductance type ballast limits fluorescent lamp electric current on the one hand; Make on the other hand to produce 55 ° ~ 65 ° phase differences between supply voltage and the operating current of fluorescent lamp, thus wait for that fluorescent lamp enters restarting, fluorescent lamp can be tended towards stability work.
Because inductance type ballast circuit structure is simple, long service life, as a kind of ballast coordinating fluorescent lamp work, its occupation rate of market is still larger.But it exists, and power factor is low, low-voltage startability is poor, energy consumption large, consume the shortcomings such as copper material is many, heavy.Power is the half of Inductive ballast self-heating energy loss close to the total power consumption of lamp package of 40W fluorescent lamp, thus it had at leisure efficient, energy-conservation, lightweight electric ballast replace.
Fluorescent lamp low-light illumination auxiliary device described in the utility model utilizes the advantage that fluorescent lamp luminous efficiency is higher, its power consumption is only with several milliamperes, just there is suitable brightness, substantially can see the article such as table, chair, clothing clearly in the indoor at night, be applicable to the old,weak,sick and disabled, children, baby night do altar lamp use.No matter and in winter, summer, or can light when AC supply voltage is lower.Because its power consumption is little especially, fluorescent lamp and electronic component can use for a long time and can not damage, achieve energy-conservation, cut down expenses, the object of environmental protection.
The circuit of described fluorescent lamp low-light illumination auxiliary device all uses ordinary electronic components and parts to make, and its cost only needs a few yuan, and it is well suited for carrying out batch exploitation for factory.
Below describe in detail high-power ventilating fan time-base circuit intermittent control apparatus described in the utility model necessity involved in implementation process, guardian technique content.
Utility model content
Goal of the invention and beneficial effect: fluorescent lamp low-light illumination auxiliary device described in the utility model utilizes the advantage that fluorescent lamp luminous efficiency is higher, its power consumption is only with several milliamperes, just there is suitable brightness, substantially can see the article such as table, chair, clothing clearly in the indoor at night, be applicable to the old,weak,sick and disabled, children, baby night do altar lamp use.No matter and in winter, summer, or can light when AC supply voltage is lower.Because its power consumption is little especially, fluorescent lamp and electronic component can use for a long time and can not damage, achieve energy-conservation, cut down expenses, the object of environmental protection.The circuit of described fluorescent lamp low-light illumination auxiliary device all uses ordinary electronic components and parts to make, and its cost only needs a few yuan, and it is well suited for carrying out batch exploitation for factory.
Circuit working principle: the core circuit of fluorescent lamp low-light illumination auxiliary device uses a kind of full-wave voltage doubler, because 2 capacitances used are very little, so the ripple component in direct current is very large, make output current and power also very little, it is not enough to excite completely the combustion fluorescent material in fluorescent tube H on mercury vapour point tube wall, but fluorescent tube H can be made to glimmer.Be characterized in: power consumption is extremely faint when fluorescent tube H glimmers, be particluarly suitable for using when alternating current voltage is low especially, as long as circuit connection is errorless, circuit ON AC power fluorescent tube H can glimmer.
Technical scheme: fluorescent lamp low-light illumination auxiliary device, it comprises 220V AC power, full wave and voltage doubling rectification and load circuit, it is characterized in that:
Full wave and voltage doubling rectification and load circuit: it is by mains switch SW, silicon rectifier diode D1, silicon rectifier diode D2 and electric capacity C1, electric capacity C2 and fluorescent tube H forms, 220V AC power live wire end L connects one end of electric capacity C1 and one end of electric capacity C2 by mains switch SW, the negative pole of silicon rectifier diode D1 connects the other end of electric capacity C1 and two lamp bases of fluorescent tube H side, 220V AC power zero line side N connects the positive pole of silicon rectifier diode D1 and the negative pole of silicon rectifier diode D2, the positive pole of silicon rectifier diode D2 connects the other end of electric capacity C2 and two lamp bases of fluorescent tube H opposite side.
