Abstract
The utility model relates to a high-voltage pulse starting type fluorescent tube seat. The lamp comprises a lamp tube bracket, an inductive ballast, a bridge rectifier device and the like. The power supply is connected to two input ends of the bridge rectifier after passing through the inductive ballast, and two output ends of the bridge rectifier are respectively connected to two ends of the fluorescent tube. One or both opposite arms of the bridge rectifier device are also connected in parallel with a capacitor. The utility model can start and work normally under lower voltage, and the lamp filament can be used continuously after being broken. In addition, the stroboscopic phenomenon is overcome, and the lighting effect is improved.
Description
The utility model relates to a kind of daylight base, a kind of daylight base with the high-voltage pulse starting drive.
Present daylight base all is to use traditional inductance type ballast and double-metal sheet type starter.There is following deficiency in this lamp socket: (one) often voltage is on the low side in peak times of power consumption, causes the ballast self induction voltage fluorescent tube that makes on the low side to be difficult to starter; (2) behind the filament blow owing to can't form the starter loop, make fluorescent tube can not continue to use.Therefore the present daylight base utmost point need improve.
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of can fast starting under low-voltage, tube filament can continue the daylight base of use after blowing.
The utility model comprises traditional fluorescent lighting fixture, Inductive ballast and the bridge-type rectifier be made up of four diodes etc.Be access to an input of bridge-type rectifier behind the one end tandem electric inductance ballast of power supply, the other end of power supply directly is access to another input of bridge-type rectifier; Two outputs of bridge-type rectifier are access to the two ends of fluorescent tube respectively; In addition, at an arm of a bridge-type rectifier electric capacity in parallel or at each electric capacity in parallel of two relative arms.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a surface structure schematic diagram of the present utility model.
Fig. 2 and Fig. 3 are two kinds of circuit diagrams of the utility model.
Among Fig. 1, (1) is fluorescent lighting fixture, and (2) are ballast, and (3) are bridge-type rectifier.For attractive in appearance, ballast (2) and rectifying device (3) place in the support (1).
Circuit diagram shown in Figure 2 is at an arm (D of bridge-type rectifier
3) electric capacity (C in parallel
1).This circuit is applicable to 30W and the following fluorescent lamp of 30W.Circuit shown in Figure 2 is then at two relative arm (D
2And D
3) respectively be parallel with an electric capacity (C
1And C
2), this circuit is applicable to 40W or the above fluorescent lamp of 40W.
The initial instantaneous of energized produces the instantaneous high pressure pulse in lamp tube ends, and with glow starting fluorescent lamp, behind the tube starting, both end voltage is reduced to normally.Even under low voltage, also can produce sufficiently high pulse voltage and make tube starting and keep operate as normal.Constitute the loop owing to all need not the two ends filament under starter and operating state, the fluorescent tube of the filament that broken also can use, thereby has prolonged the useful life of fluorescent tube.
Experiment showed, that the utility model still can make tube starting and normally luminous under 160 volts of low pressure, thereby wide adaptability.Also overcome stroboscopic phenomenon in addition, improved illuminating effect.
Claims (1)
1, a kind of high-voltage pulse starts the formula daylight base, comprise fluorescent lighting fixture (1), Inductive ballast (2) and bridge-type rectifier (3) etc., it is characterized in that: be access to an input of bridge-type rectifier behind the end tandem electric inductance ballast of power supply, the other end of power supply directly is access to another input of bridge-type rectifier; Two outputs of bridge-type rectifier are access to the two ends of fluorescent tube respectively; An arm of bridge-type rectifier electric capacity in parallel, or each electric capacity in parallel of two relative arms.
