Abstract

The utility model relates to a universal starter for a fluorescent lamp. The utility model is composed of a fourfold press rectifier circuit which is connected with capacitors C1-C4 and commutation diodes D1-D4, and the fluorescent lamp is directly connected with the output terminal of a glow starter. The starter is a new generation product of a traditional start device which is composed of a fluorescent lamp ballast and a glow starter, and the utility model is provided with versatility and can fit for fluorescent lamps and daylight lamps with different specifications and parameters. The utility model can normally and rapidly glow in a wider voltage range, particularly a low voltage condition, and the utility model has good electric performance, such as no stroboflash, electricity saving and service life of a fluorescent lamp improvement. The utility model has the advantages of simple manufacturing technique and low cost.

Description

Universal starter for fluorescent lamp

The utility model belongs to the starting drive of fluorescent lamp, fluorescent lamp.

Fluorescent lamp, fluorescent lamp are present widely used ligthing paraphernalias, general fluorescent lamp, fluorescent lamp all must use ballast and starter to start and operate as normal, this traditional starting drive not only benzene is heavy, there is electromagnetic noise to take place when having work, build-up of luminance speed is slow, under low-voltage, be difficult to electric shortcomings such as build-up of luminance, and the ballast of the necessary adapted different parameters model of the fluorescent tube of different size and parameter, use inconvenient.Also have at present and use electric ballast to start fluorescent lamp, but the general structure of this starting drive is complicated, price is also more expensive, is difficult to popularize.

The purpose of this utility model is the shortcoming at existing fluorescent start device, a kind of fluorescent lamp, fluorescent lamp that can adapt to the different size parameter proposed, in the voltage range of broad, particularly under low voltage condition, can make fluorescent lamp, the normal build-up of luminance work of fluorescent lamp, it is quick to have build-up of luminance, no stroboscopic and noise etc. are electric property preferably, and manufacturing process is simple, the fluorescent lamp generally starting device that cost is low.

The purpose of this utility model can be realized by the structure that following examples disclosed.

Fig. 1 is the circuit theory diagrams of this fluorescent lamp generally starting device embodiment;

Fig. 2 is the electric hookup of this fluorescent lamp generally starting device.

As shown in Figure 1, this fluorescent lamp generally starting device 1 is by capacitor C ₁, C ₂, C ₃, C ₄With rectifier diode D ₁, D ₂, D ₃, D ₄Connect into four voltage doubling rectifing circuits and constitute, the annexation of each element is as follows: C ₁Serial connection C ₂, its point of contact a is an input of starter, C ₃Polyphone meets C ₄, its tie point a ' is another input of starter, C ₃The other end connect D ₃Positive pole, its tie point b is an output of starter, C ₄The other end connect D ₄Negative pole, its tie point b ' is another output of starter, C ₁The other end be connected to D ₃Negative pole and D ₁Positive pole, C ₂The other end connect D ₄Positive pole and D ₂Negative pole, D ₁Negative pole and D ₂Positive pole link input a '.

During use, (do a termination electrode after two utmost point pin short circuit of the every end filament of fluorescent lamp uses fluorescent lamp 2 two end electrodes, perhaps every end filament is only made a termination electrode with any utmost point pin wherein and is used) receive the output b and the b ' of fluorescent lamp starter 1 respectively, external power is then from the input a and a ' access (as shown in Figure 1 and Figure 2) of starter.

During the work of this fluorescent lamp generally starting device, in the moment of energized, the high pressure that will produce four times of input voltages at output b, b ' two ends is added to the two end electrodes of fluorescent lamp, makes fluorescent lamp build-up of luminance immediately, behind the fluorescent lamp build-up of luminance, the fluorescent lamp two ends will maintain work under the normal rated operational voltage.

The C of this fluorescent lamp generally starting device ₁, C ₂, C ₃, C ₄Capacitance to get 4.75 μ f be good.Used electric capacity, the reverse voltage that withstand voltage and rectifier diode bears should be at more than 2 times of supply voltage.

The utlity model has following good electric property:

One, can under the supply voltage of 145V-250V, make the smooth build-up of luminance of fluorescent lamp and normal operation, fluorescent lamp can be in millisecond rapidly soft start, no stroboscopic phenomenon.

Two, can use fluorescent lamp and the supporting effect of fluorescent lamp with any specification and the parameter of a kind of fluorescent lamp generally starting device and 8W-40W, light fixture can exchange arbitrarily, and all has normal result of use;

Three, the fluorescent tube that filament has been burnt as long as fluorescent tube is air tight, all can make light pipe recover lost eyesight with this starter, this as many as useful life that prolongs light pipe.

Four, owing to save wasted work element such as ballast, this starter can make fluorescent lamp or fluorescent lamp economize on electricity and improve brightness.

Five, this starter manufacturing process is simple, and cost also has only half of an ordinary electronic ballast, thereby is easy to extensively promote the use of.

Claims

1, a kind of its input termination power, the fluorescent lamp generally starting device of output termination fluorescent lamp is characterized in that this starter is by capacitor C ₁, C ₂, C ₃, C ₄Connect into four voltage doubling rectifing circuits and constitute, the annexation of each element is: C ₁Serial connection C ₂, its point of contact a is an input of starter, C ₃Serial connection C ₄, its tie point a ' is another input of starter, C ₃The other end connect D ₃Positive pole, its tie point b is an output of starter, C ₄The other end link D ₄Negative pole, its tie point b ' is another output of starter, C ₁The other end link D ₃Negative pole and D ₁Positive pole, C ₂The other end link D ₄Positive pole and D ₂Negative pole, D ₁Negative pole and D ₂Positive pole link input a '.
