Reasons for prematurely burning out
Lamp from a pressed lamp with an old source on a bright light, the design is extremely simple - a tungsten spiral is installed in a sealed glass pot, which is disgustingly flowing through currents, heating up and the soil and shining.
Such simplicity, however, does not mean long-term and hopefulness. Techniyat is operational for about 1000 hours, and sometimes only a little. It may be caused by:
- current overvoltages;
- often included and excluded;
- other causes such as temperature fluctuations, mechanical damage and vibrations.
In the basin, we can see how we can reduce to a minimum the harm from being turned on on the lampata. Kogato svetlinata e is excluded, bobinata e is studen. Resistance to this is 10 five low from the goods on the burning winding. The main mode of operation is the burning condition of the lamp. It is known from the law on Ohm that it depends on resistance, sharply low, sensible in terms of goals.
When you turn on the lamp, prez the student winding the current to the current, but with the heat on, the soil and the paint.The primary temple of the tok ima is a destructive effect of the top of the bobbin. For yes, avoid tov, tryabva and organize smoothly turning on the lamp from the lit chick.

Principle for action
For yes, limit the current on the switch on to the lamp from the pressed switch, you can apply the initial voltage and gradually increase it to the nominal value. For yes, send the tov, use the device for smoothly turning on the lamp from the pressed button.
The device is switched on through the preservation of the conductor between the switch and the lighting body. When you apply voltage, at the first moment from time to time it is close to zero, gradually increasing the voltage for smoothly zapalvane. Ordinarily, those are all connected according to the schematic diagram for a phase-pulse controller for thyristors, triacs or field effect transistors.
The ramp-up speed depends on the circuit diagram of the device, usually 2-3 seconds from 0 to 220 V.
The main characteristic of the protective unit is the permissible power for connecting goods. It is common for se namira in the range of 100-1500 vata.
Prepare solutions
Protect the block behind the body lights that are sold in almost every home and electrical store. Such a unit may be named differently starting from spomenatoto in mountain, for example: “Device for the protection of halogen lamps and lamps with a lit lamp” or another similar name. Somehow it’s been bleached more, when buying, it’s basically something, you’ll pay attention to something, and the power is on the ignition unit.
A wide range of products from this device is produced under the brand name Granite.
Offer from "Granite"
Ima and miniature block for navigator; they can conveniently yes be skriti in the commutation kutia, but do not sap from the conductor in the heat. Toy scho so take it in the same body, which is based on a table lamp, or between a tavana and a polylea, whichever is possible.

Schemes
This device for smoothly switching on a lamp with a lit lamp and a halogen lamp is not particularly difficult from a visible point on an electric chain, then you can even use it yourself. The process on the citizen can be perverted:
- montirana installation;
- on the layout;
- on top of a printed handkerchief.
And depending on your skills and abilities, we hope the option is even better on a printed scarf; in this case, it’s better if you are at a distance from the surface of the installation, if you don’t know how to characterize the installation in 220 V chains.
Smoothly turning on 220 V lamps: thyristor circuit
Parvata scheme e is shown in the figure along the -dol. The main functional element is a thyristor, included in the frame for a diode bridge. Denominate for vsichki signing elements. How to use it smoothly for a hearth lamp, table lamp or other portable lamp, or conveniently shut into the housing, a suitable connector for external installation. At the exit, install the nest behind the lampata. Vsshchnost tova e normal dimer and nyama mek start kato takv. Just turn the smoke on the potentiometer, then gradually increase the voltage in the lamp. By the way, such a prefix e is suitable and regulated for power for a soldering iron or other electrical devices (stove, engine collector, etc.).
Option for drawing on the schematic
Smoothly turn on for 220 V lamps: chain for triac
You can paint a broya on the part, and yes, fold the schematic diagram, which is installed in the protection block. Tova e is shown in the figure along the length.
triac chain
Kolkoto for a long time, the constant R2C1 on the verigata is sensible for a long time, zapalvaneto. For yes, increase the time, try to increase the capacitance of C1, keep in mind whether the capacitor is polar or electrolytic. Capacitor C2 and the cost of the voltage at least 400V - the product is non-polar capacitor.
For yes, increase the power by connecting the lamps, change the VS1 triac to whatever is suitable for your product.
Throttle L1 is a filtering element, necessary for painting on the noise in the noise from turning on the triac. It’s not necessary to use it, it’s not influencing the work on the verigata.
When SA1 (switch) is not switched on, the current is ground and flow pres lampat, choke and capacitor C2. For the sake of reactive resistance to the capacitor, the current is opposite to the pressure of the lampate e small. Once upon a time, until some time C1 is charged, reaching Prague on the decoction on the triac, now it’s still flowing, turn on the lamp on the fire.
Soft turn on lamp 220 V: chain on IC KR1182PM1
Ima option for smoothly turning on with the help of the KR1182PM1 chip, you can start smoothly on lamps and other products with power up to 150 watts. A detailed description on the tazi microcircuit can yes, try it here:
and further down the circuit for the device is extremely simple:

Or there is a slightly modernized version, sometimes including a powerful product:
Scheme developed
Additionally, a thyristor BTA 16-600 is installed, also designed for current up to 16 A and voltage up to 600 V, the product can be seen from the marking, but you can take any other.For starters, you can turn on supplies up to 3.5 kW.
Smoothly turn on 12 V lamps
Most lamps with a voltage of 12V are used for spotlights. It is actually used by electronic transformers for converting 220V to 12V. The next device is for a smooth start of the trebva and it is connected to a cable for storing the conductor to the electronic transformer.
Smoothly turn on the lamp in colata
Ako task is to organize the smooth switching on of 12 V car lamps, then the circuits of the yama and work here. The electric cable for the car is powered by a voltage of 24 or 12 V DC. Here you can use linear or impulse chains, so call PWM controllers.
Nay-forgive the variant of the bi-beat, and yes, from the use of the two-degree scheme on the prevvklyuchvane.
Two-stage scheme on the pre-switch
Tazi veriga is installed in parallel with turn on the lamp. From the beginning, the pres resistor flows through the current and the lamp is muted. The trace is short time, about half a second, the relay is switched on and the current is interrupted by the power of the contacts, those from the home country bypass the resistor and light up with a brightness panel.
The value of the resistor e is from 0.1 to 0.5 Ohm, but it’s also possible with high power - about 5 W, for example, in a ceramic case.
The second option is to save the impulse block for smoothly zapalvane. The scheme is more complex:
