Scheme for connecting a daylight lamp without a starter. Highlighting a fluorescent lamp without a choke. What calls for trouble in an energy-saving lamp

Widely lit fluorescent lamps do not help shortcomings: during the hour of the robots, the buzzing of the throttle is heard, in the system of life there is a starter, which is not good for the robot, and the headlight lamp is too hot, as it can burn out, through which the lamp can be replaced with a new one.

Fluorescent lamp becomes "eternal"

Here is shown a scheme, which allows you to use the repaid nedolіki. There is no sound buzzing, the lamp is spalling mittevo, the day is not a good starter, and, what’s more, you can beat the lamp with a thread.

Capacitors C1, C4 are made of paper, with a working voltage 1.5 times greater than the voltage of life. Capacitors C2, C3 bazhano shob were mica.

Resistor R1 is obov'yazkovo drotyany, yogo opіr lie in the lamp's tightness.

Data elements of the scheme, fallow in the intensity of fluorescent lamps, indicated in the table:

Diodes D2, D3 and capacitors C1, C4 represent a double-wave rectifier with voltage subtraction. The values ​​of capacities C1, C4 determine the operating voltage of the lamp L1 (which is more capacitance, more voltage on the electrodes of the lamp L1). At the moment of switching on, the voltage at points a and b reaches 600 V, as it is applied to the electrodes of the L1 lamp. At the moment of ignition of lamp L1, the voltage at points a and b changes normal work lamp L1, rated for 220 St.

Zastosuvannya diodes D1, D4 and capacitors C2, C3 pushes the voltage up to 900, which ensures that the lamp L1 is lit at the moment it is turned on. Capacitors C2, C3 at the same time receive a suppressed radio code.

Lamp L1 can be used without D1, D4, C2, C3, but if necessary, the inclusion changes.

The lamps of the daylight do not care for the whole day “survivability”, in the same time with the splendid light bulbs of the roasting, once they go out of tune and cease to shine.

Obviously, the term їх service is not comparable with light models, but, as it appears, in case of a serious breakdown, all cis LB or LD lamps can be renewed without serious capital losses.

It is necessary for us to tell you in front of you what burned itself:

• herself fluorescent light bulb

• starter

• abo throttle

How tse robiti that shvidko reverify all these elements, read in the next article.

If the light bulb itself burned out and you got so light, then you can easily switch to light lighting, without a serious modernization of the lamp. And why do you want to fight dekilkom in ways.

One of the most serious problems is the throttle, which is good.

More importantly, such a luminescent lamp should be made irrelevant and discarded, or moved from the comor to spare parts for others.

Let’s think about how to start the LB lamp without a choke, just throwing some of the circuits and not putting anything else in there, you won’t get into it. The article talks about alternative options, if the throttle itself can be replaced by another element, which you have a booth at your fingertips.

How to start a fluorescent lamp without a choke

What is the reason for being shy in such acts of self-restraint and radio amateurs? The stench recommends stopping the so-called choke-free circuit for switching on fluorescent lamps.

It has a victorious place, condensers, ballast opir. Irrespective of the day of the war (the possibility of launching daylight lamps that burned out), all circuits for an ordinary dark wood coristuvach. It’s easier for you to buy a new lamp, then solder it and take the whole structure.

Therefore, I will first look at another popular way to launch LB or LD lamps with a throttle, which will burn, which will be accessible to the skin. What do you need?

You need an old burned-out energy-saving light bulb with a great E27 base.

Obviously, the circuit cannot be considered absolutely choke-free, since the choke is still present on the energy-saving board. It's just that the wine is a little smaller for the dimensions, to which the economy works at frequencies up to a few tens of kilohertz.

This minidrosel surrounds the jet through the lamp and gives a high-voltage impulse for ignition. In fact, the EPRA in the miniature version.

To that deyakі svіdomі thа thе prudent hromаdіnі, yаkі still їхі їхі їхі їхі і іpіtі priyomu, zaryayut poіbnі vorobi іn іt policemen іn wardrobes.

Change them for good reason. The number of light bulbs in a working station is too short for health, as in the plan of pulsation of light, so it is good for viprominating unsafe ultraviolet.

If you want ultraviolet light, it won't always be harsh. And for an hour bring us a lot of coriste.

In this case, do not forget that these are negative factors, however, there are also linear luminescent models. They themselves are actively lapped by those who like to grow the growth under the light of phytolamps.

Ale, let's turn to our energy-saving ones. Most often, they cease to use a spiral tube that glows (experiencing tightness, breaking, etc.).

Why is the scheme indoor unit eating is overwhelmed with cilim and neushkodzhenimi. You can cite them from our right.

Pick up a light bulb on the back. For this, along the rose line, with a thin flat twist, open and separate two halves.

At the same time, at the same time, do not tremble for the glass of a tubular flask.

For an hour of analysis, remember that a couple of places are connected. Two lines can be paid from one side, and from other sides.

Usogo you can have 4 contacts, where you and next soldered darts.

This one is obviously not forgotten about 220V living. These are the same veins that go out of the basement.

Tobto, okremo two darts right-handed and two darts left-handed. If there is anything left to do, just apply a voltage of 220V to the energy saving circuit.

The light bulb of daylight is miraculously lit and normally pracyuvatime. Moreover, to start you do not need a starter. Everything connects without interruption.

Like a starter in a circuit present, it may happen to be shunted.

How to choose the intensity of an energy-saving lamp

Such a lamp is launched mittevo, on the vіdmіnu vіd vіd dovgіh blinks аnd merekhtin zvichnіh LB аnd LD models.

What are the shortcomings of such a connection scheme? First, the working strum in energy savings with equal tension is smaller, lower in linear daylight lamps. What do I threaten?

And then, having converted the economy evenly or less for the burden of the LB, your payment is pratsyuvatim s revantazhennyam and once a babahne. So that didn’t happen, the tightness of the boards in the economy, ideally, can be 20% larger, lower for daylight lamps.

So for the LDS model at 36W, take a fee for 40W paws and more. Well, and so on, fallow in proportion.

If you remake a lamp with one choke into two light bulbs, protect the tension of both.

Why else do you need to take it yourself from the reserve, and not choose the intensity of CFLs equal to the intensity of daylight lamps? On the right, in the fact that in the nameless and inexpensive CFL bulbs, the actual tension is an order of magnitude less than stated.

Do not be surprised if you connect the old radyansky lamp LB-40, a board from the Chinese economy for the same 40W, as a result you take a negative result. Not the scheme does not work - tsia kіst commodities z pіdnebesnoї not vіdpovіdaє "zalіzobetonnim" radyansky guests.

2 schemes for chokeless inclusion of daylight lamps

If you still can pick up a folding structure for us, for the help of which you start to put on fire linear lamps, then let's take a look and such vipadki.

Samy the simplest option- the same place with a pair of capacitors and connected in series to the lance like a ballast, a light bulb is heated. Axis scheme of such selection.

The main problem is that, in a similar manner, you can start the lamp not only without a throttle, but also a lamp that has burned out, which does not have a lot of spirals on the pin contacts.

For tubes with an intensity of 18W, the following components are required:

• capacitor 2nF (up to 1kv)

• capacitor 3nF (up to 1kv)

• light bulb 40W

For tubes 36W or 40W All elements zadnuyutsya such a rank.

After which the circuit is connected to the lamp light.

The axis is one more similar to the throttleless scheme.

Diodes are selected from the return voltage less than 1kV. The strum is stale in the strum of the lamp (in 0.5A and more).

Let's light the lamp that's burned out.

In this scheme, with a lamp that burned out, the hinged lines on the ends flicker between themselves.

Select the components of the fallow according to the intensity of the lamp, try focusing on the plate below.

Like a light bulb, the jumpers are still being installed. For this reason, you don’t need to advance the spirals up to 900 degrees, like in the right models.

The electronics are necessary for ionization, they are vibrated by name and for room temperature, wind up the spiral and burn out. Everything is driven by the multiplied tension.

The whole process looks like this:

• cob in a flask

• sweat at the end

• light in the middle for the fire of which mittevo is lit

• far away, the light bulb is roaring, as if with its support it surrounds the maximum strum

• in the flask, step by step, the working voltage and strum are stabilized

• light bulb rozharyuvannya trohi dark

Shortcomings of such a selection:

• low rіven yaskravostі

• increased pulsation

And even when living fluorescent lamps with a constant voltage, you will often change the polarity on the extreme electrodes of the colby. It seems simpler, turn the lamp over in front of the new skin.

Otherwise, the mercury vapor is taken from one of the electrodes and the lamp without periodic maintenance will not last long. This is called cataphoresis of the introduction of mercury vapor into the cathode end of the lamp.

Lamps of day light from the first releases and often dossi are ignited behind the auxiliary electromagnetic ballast - EmPRA. The classic version of the chiming lamp looks like a hermetic glass tube with pins on the ends.

How fluorescent lamps look

The middle of it is filled with an inert gas from mercury vapor. Її installation is carried out at the cartridge, with which the voltage is applied to the electrode. Between them, an electric discharge is created, which calls for an ultraviolet light, like a ball of phosphor, applied to the inner surface of the glass tube. In the aftermath of this z'yavlyaєtsya svіtіnnya. The circuit for switching on fluorescent lamps (LL) is provided by two main elements: an electromagnetic ballast L1 and a lamp of the SF1 category.

Scheme of switching on LL with an electromagnetic throttle and a starter

Impregnation schemes with EMPRA

Attachment with a throttle and a starter is based on this principle:

1. Applying voltage to the electrode. The strum through the gaseous center of the lamp and on the back does not pass through the її great opіr. Vіn go through the starter (St) (small below), for which a glowing discharge is established. With this, a strum passes through the spirals of the electrodes (2) and starts to grow.
2. The starter contacts are rozіgіvayutsya, and one of them flicker, so like vin zvіmetalu. The strum passes through them, and the discharge is pinned.
3. The starter contacts stop glowing, and after reaching the bimetal contact, it starts to glow again. At the throttle (D), a voltage impulse is generated for the self-induction chamber, which is sufficient for the ignition of the LL.
4. A strum passes through the gaseous center of the lamp, after the lamp is started, the valves change at once due to the voltage drop on the throttle. When the starter is left switched on, this stream is not enough for the first start.

Scheme of switching on a fluorescent lamp

Capacitors (C 1) and (C 2) in the circuit are recognized for lowering the shift rate. Capacitance (З 1), connected in parallel to the lamp, reducing the amplitude of the voltage impulse and increasing the voltage. As a result, the term of service of the starter and LL is increased. Capacitor (C 2) at the input ensures the reduction of reactive storage power (cos increases from 0.6 to 0.9).

As you know, how to connect a fluorescent lamp with filaments that have burned out, you can win in the EmPRA circuit after a small change in the circuit itself. For this spiral, they flash briefly and sequentially connect a capacitor to the starter. Behind such a scheme, it was possible to proprate another hour.

A wide range of ways to switch on with one inductor and two fluorescent lamps.

Emphasis of two fluorescent lamps from a hot choke

2 lamps are connected sequentially between themselves and with a choke. For skin problems, it is necessary to install a parallel connected starter. For this victorious one, there is one visible pin from the ends of the lamp.

For LL, it is necessary to put in special chemicals, so that the stench does not stick to the contacts from the high starting jet.

Sealing without electromagnetic ballast

To continue the life of daylight lamps that have burned out, you can install one of the switching circuits without a choke and a starter. For which vicorist, multiply the voltages.

Scheme of switching on fluorescent lamps without a choke

The voltage threads flicker briefly and apply voltage to the circuit. After straightening, it will increase 2 times, and that’s enough, so that the lamp is knocked down. Capacitors (З 1), (З 2) pick up a voltage of 600 V, and (З 3), (З 4) - a voltage of 1000 V.

The way to go is the same for reference LL, but the stench is not to blame for the practice with the constant strum. After a certain hour, mercury is collected at about one of the electrodes and the brightness of the light falls. For inspiration, you need to turn the lamp over, thereby changing the polarity yourself.

Connection without starter

Zastosuvannya starter pіdvischuє hour lіgіvu lamp. For whom the term yogo service is small. Electricity can be connected without it, as for which you can install the secondary transformer windings.

Connection diagram for a fluorescent lamp without a starter

There, where the starter is not victorious, there is a sign on the lamp shvidkogo start- RS. If you install such a lamp with a starter start, it can quickly burn out the spirals, because more hours of heating have been allocated for them.

Electronic ballast

The electronic control circuit of the EPR came to replace the old jacks of daylight for the adoption of the authorities of their shortcomings. Electromagnetic ballast saves energy, often makes noise, goes out of tune and when the lamp is switched on. In addition, the lamps flicker through the low frequency of the voltage of life.

EPRA є electronic block which takes a little time. Luminescent luminaires are easy and quick to start, without creating noise and ensuring even illumination. The scheme has been given a few ways to protect the lamp, which will use the greater term of exploitation and make the robot safe.

EPRA pratsyuє advancing rank:

1. Rozigrіv elektrodіv LL. Starting up is quick and soft, which is the best term for lamp service.
2. Pіdpal - generating a high voltage impulse, which breaks through the gas near the flask.
3. Gorinnya - support for a small voltage on the electrodes of the lamp, which is sufficient for a stable process.

Electronic choke circuit

On the other hand, the voltage is changed and straightened behind the help of the diode bridge and smoothed out by a capacitor (2). Next, a high-frequency voltage generator was installed on two transistors. The purpose is to use a toroidal transformer with windings (W1), (W2), (W3), two of them are connected in anti-phase. The stench successively vibrates the transistor keys. The third winding (W3) supplies the resonant voltage to the LL.

A capacitor (4) is connected in parallel with the lamp. The resonant voltage is applied to the electrode and breaks through the gas medium. At that hour, the roasting threads were already roasted. When the lamp opir is ignited, it drops sharply, calling out a decrease in voltage to a sufficient value, in order to raise the fire. The startup process lasts less than 1 s.

Electronic circuits may have the following advantages:

• start-up from a given hour;
• it is not necessary to install a starter and a massive throttle;
• the lamp does not blink and does not buzz;
• yakіsna svіtlovіddacha;
• compactness of the attachment.

The EPRA switch allows you to install it in the base of the lamp, as it was also changed to a reheated lamp. This gave rise to new energy-saving lamps, which can be turned into a standard standard cartridge.

The process of operation of the lamp light is old, and for them it is necessary to increase the working voltage. In the EmPRA circuit, the voltage of the discharge, which is smoldering, changes in the starter. If so, you can switch off the electric current, which will help the starter and turn on the LL. The next time it starts up again. It’s like a blink of a lamp to bring to the її way out of the fret at once from the choke. There is no such thing in the electronic ballast circuit, the shards of the electronic ballast are automatically adjusted to change the parameters of the lamp, changing the friendly mode.

Lamp repair. Video

For the sake of repairing a fluorescent lamp, you can watch this video.

Attachment of LL and schemes of their inclusion are constantly developing in direct reduction technical characteristics. It is important to remember to collect different models and operate it correctly.

Not long ago, marveling at the whole box of burned-out energy-saving lamps, mainly with electronics, almond threads, which burned out, I burned out a fluorescent lamp, and thinking - I need to blow all the good stuff. As you can see, LDS with burnt threads of roasting needs to live with a straightened streak of merezhі with a starter-free addition to the launch. At the same time, the threads of roasting the lamps are shunted with a jumper and served on a yak high voltage for raising the lamp. It feels colder to light the lamp, sharply increases the voltage on it, at start-up without front heating of the electrics.

If you want to be ignited with cold electrodes, more important mode, lower switching on, this method allows you to burn a luminescent lamp for lighting for a long time. As you can see, lighting a lamp with cold electrodes will increase the voltage up to 400...600 V. It is possible to implement it directly, the voltage will be higher than the input string 220V. Like a ballast, a very low-voltage light bulb is installed, and if you want to change the lamp instead of the throttle, the economy of such a lamp will be reduced, so you can turn the lamp on to a voltage of 127 and її turn on the lamp fast strumu sequentially with a lamp, then matimem I will have enough brightness.

Diodes be-yakі vipryamlyauchі, on a voltage vіd 400V and strum 1А, it is possible and radyanski brown KC-shki. Capacitors are also with a working voltage of at least 400V.

Danish attachment is used as a voltage susceptor, the voltage is removed, which is added to the cathode - the anode of the LDS. After the ignition of the lamps, the attachments switch to the mode of double-wave rectification with active voltage and the voltage, however, is divided between the lamps EL1 and EL2, which is true for LDS with a voltage of 30 - 80 W, which may work at an average voltage of about 100 V. With such a light circuit, the lamp Roasting becomes approximately a quarter of the flow of LDS.

For a fluorescent lamp with an intensity of 40 W, a heating lamp of 60 W, 127 V is required. And for LDS with a power of 30 W, two lamps can be heated for 127 to 25 W skin, turning them on in parallel. The light flux from two lamps is about 17% of the light flux of LDS. Such an increase in the light flow of the lighting lamp in a combined lamp is explained by the fact that the stench works at a pressure close to nominal, if their light flow is close to 100%. At that very hour, when the pressure on the lamp is heated, it is close to 50% of the nominal, their light flux becomes less than 6.5%, and the tension is reduced - 34% of the nominal.

The scheme for switching on fluorescent lamps is richly folded, lower for heating lamps.
The zapaluvannya will require the presence of special launching devices, and in view of the quality of the installation of these devices, the term for the operation of the lamp should be deposited.

In order to understand how to start up the system, it is necessary to familiarize yourself earlier with the attachment of the lighting fixture itself.

The fluorescent lamp is equipped with a gas-discharge lamp of light, the light stream of which is formed mainly for the light beam of the phosphor applied to the inner surface of the bulb.

When the lamp is turned on in mercury vapor, with which the test tube is filled, an electronic discharge is generated and that viniclo with which ultraviolet light is added to the coating of the phosphor. In this case, the transformation of the frequencies of the invisible ultraviolet vibration (185 and 253.7 nm) into the vibration of the visible light occurs.
Qi lamps may have low energy savings and become very popular, especially in virobnicheskih applications.

Schemes

When fluorescent lamps are connected, a special start-regulating equipment is used - PRA. There are 2 types of control gear: electronic - EPRA (electronic ballast) and electromagnetic - EMPRA (starter and throttle).

Scheme of connection from the stopover of the electromagnetic ballast or EmPRA (throttle and starter)

Main shortfalls

• Porivnyannі zі scheme with electronic ballast has 10-15% more electricity wattage.

• Long start-up no less than 1 to 3 seconds (due to lamp wear)

• Unsuitable for low temperatures dovkilla. For example, a charge in the garage, so you don’t get scorched.

• The stroboscopic result of the flashing of the lamp, which is filthy pouring onto the surface, moreover, the details of the layout, which are wrapped synchronously with the frequency of the merge, are made unruly.

• The sound of the buzzing of the throttle plates, which grows with the hour.

Switching circuit with two lamps and one inductor. It should be noted that the inductance of the inductor is to blame but sufficient for the dimming of these two lamps.
It should be noted that in the last circuit of switching on two lamps, starters for 127 Volts are used, stinks will not be used in a single-lamp circuit, for which starters for 220 Volts are needed.

Tsya scheme is de, like a bachite, there is no starter or throttle, it is possible to stop the lamps and burn out the roasting threads. In such a situation, it is possible to ignite the LDS for the help of a moving transformer T1 and capacitor C1, which surrounds the strum, which flows through the lamp through the 220-volt line.

This scheme is all for the same lamps, for which the threads of roasting have burnt out, but here it’s not necessary to move the transformer, which will obviously simplify the design of the extension.

And the axis of such a circuit from the stoppage of the diode vipryamny bridge is usuvaє її merekhtinnya lamps with the frequency of the measure, as it becomes even more memorable when її old.

or more foldable

If your lamp has a viyshov in a fret, a starter or a lamp flashes constantly (at once with a starter, it’s possible to be surprised at the starter housing) and under the hand of a dumb man, replace it, you can light the lamp without it - enough for 1-2 seconds. short-circuit the starter contacts or insert button S2 (carefully unsafe voltage)

the very same vipadok, but already for a lamp with a burnt thread.

Scheme of connection from the stopover of the electronic ballast or ballast

Electronic Starter Control Device (EPRA) to control the electromagnetic supply to the lamps of a voltage not of a transverse frequency, but of a high-frequency one at 25 to 133 kHz. And tse povnistyu include the possibility of the appearance of a merekhtinnya lamps for the eyes. In the EPRA there is a self-oscillating circuit that turns on the transformer and the output cascade on transistors.
