Abstract
The utility model relates to a device for stabilizing glow of fluorescent lamps, which is characterized in that the device comprises a casing and an alternating current/direct current change-over circuit which comprises diodes D1, D2, capacitors C1, C2 and an indicating lamp E. After the utility model is used, electric current does not pass by the filament in a florescent lamp, so the service life of the florescent lamp can be prolonged; besides, because a ballast and a starter are not used, when an alternating current of 220V voltage is lower, a florescent lamp F can be lightened normally without any noise. The utility model has the advantages of simple structure and low cost, and the used elements are known component parts which are easy to implement.
Description
The utility model relates to a kind of device for stablizing glow, especially a kind of device for stablizing glow of fluorescent-lamp-use.
Present employed fluorescent lamp, all be directly to adopt AC power, because bigger alternating current is by tungsten filament in the lamp, tungsten filament is evaporated, therefore the influence in useful life to fluorescent lamp is bigger, and the light that can cause fluorescent lamp has tangible scintillation, and people's eyes are had spread effect.If the alternating voltage of use is crossed when hanging down, fluorescent tube can not normally use in the starter influence, and when higher as if voltage, the electric current increase by filament makes its lost of life.General in addition fluorescent lamp must use ballast and ball gram, when because of its connection or internal structure problem being arranged sometimes, noise can occur at work, or fluorescent lamp can not be lighted.
The purpose of this utility model is for a kind of fluorescent-lamp-use device for stablizing glow is provided, and this device for stablizing glow can replace ballast and ball gram, and when work noiselessness, and can emit stable light.
Architectural feature of the present utility model is by a housing and comprises diode D1,2, capacitor C1,2 and the alterating and direct current change-over circuit of indicator light E form, an end of AC power and the positive pole of diode D1 join, the while also joins with the negative pole of diode D2.The negative pole of diode D1 joins with the end of capacitor C1 and the end of indicator light E simultaneously, the end of the other end of capacitor C1 and capacitor C2 joins, draw an end B in the joint of capacitor C1 and C2, the other end of this B point and AC power joins, the anodal of diode D2 joins with the other end of capacitor C2 and the lower end of fluorescent lamp F simultaneously, and the upper end of the other end of indicator light E and fluorescent lamp F joins.
Below in conjunction with accompanying drawing architectural feature of the present utility model is further specified.
Accompanying drawing is alterating and direct current change-over circuit figure of the present utility model.
The 220V alternating current by behind the circuit as shown in the figure, just can be carried out rectification, and to the two ends of fluorescent lamp F output dc high-voltage, under the effect of dc high-voltage, the inflation in the fluorescent lamp F is ionized, the gas after being ionized participates in conduction, makes fluorescent lamp luminous.Because direct current is stable, the light of fluorescent lamp is softer, does not have the flickering of alternating current.
After using this device for stablizing glow, the obstructed overcurrent of filament in the fluorescent lamp, so the life-span of fluorescent tube can prolong greatly.Owing to do not use ballast and ball gram, when the 220V alternating voltage was on the low side, fluorescent lamp F also can normally light, and noiselessness in addition.
The utility model is simple in structure, and cost is low, and employed element all is the general known part of purchasing, so implement easily.
