Kakvi lampi sa installirani in the spotlight
Title: Searchlights
Spotlight sa aimed at a nai-wide application in almost all-round areas on our belly. But the effectiveness of any searchlight depends on the use of lamps in the lamps. In the basin, we will analyze how the lamps for the searchlights exist and which are used from here and there.

How do you see the lampi se use nai-chesto
According to the principle, the searchlight is used almost in every kind of light source, including metal halogens (MHL), living lights (DRL, DRI), light-emitting diode (LED) and many others. But find a lamp for a spotlight, or a conventional lamp with a lit lamp, or a halogen lamp. Some se spray on tyah. For yes, we will analyze the differences between these two types of sources for light, and we can see how they work.
The lamp with a lit flask is made from a glass jar, in some cases two darzhachs per electrode are used. The wolfram spiral is open between the electrodes - such is the name of the tether from the stinging liquid. The flask is filled with inert gas and is equipped with a base, through some device it is connected to an electrical grid.
Device with a lamp with a pressable button
Numbers on the figure show:
- Glass flask.
- Darzhachi-electrody.
- Wolfram spiral.
- inert gas.
- Base / plinth.
When you apply a voltage to the electrode, the coil is heated and the soil and the light is bright, and the inert gas is not allowed to spiral and it is oxidized and burnt out.
Let's do something right now halogen lamp… The design is practically the same: a cup, an electrode, a spiral, a base.
Device with halogen lamp
Numbers on the figure show:
- Quartz glass flask.
- Darzhachi-electrody.
- Wolfram spiral.
- An inert gas with an admixture of halogens.
- Base / plinth.
This is the kolbat itself, which is directed from refractory quartz glass (for protection - we’ll analyze it in more detail), and by adding inert gas, adding halogen - bromine or iodine. When you apply a voltage to the device, you heat up the spiral and radiate light. That is, the only halogen mug is the mug removed from the jar. Obarkan itself from halogen and glass.
The fact is that the gas is sharply and hopefully inert and the spiralate predisposes to oxidize, so everything is steamed out, pulled out and in the extreme mark of the burnt out. Halogent, from a different country, e in the state and catch the "eject" tungsten molecules and da gi varne into a spiral.
Tova send it, if possible, to the temperature on the winder, and then the brightness to the samata krushka. In addition, the operating life of the device has already been increased (up to 8,000-12,000 hours I will cut 1000 for a lamp from a lit bug). And ty kato is the temperature on the spiral of the camp at the temple, togava kolbata is back and all the heat is higher. This is why quartz glass was used instead of ordinary glass, but it was usually glass that was simply set under such conditions.
Important! Many times a halogen lamp is se- lected with a metal halide lamp. Tova sa completely different devices, working on different principles.
The photo above shows a linear halogen flask, but the product is not the only factor. Ima halogenic uredi with various sizes and shapes - depending on the purpose of the cruiser and the design of the spotlight. For example, here is a spotlight, which is protecting the lamp from a linear lamp, is shown along the length:

And this device is made from a miniature halogen cap.

Dnes halogen lamps behind the spotlights, for the sake of golyamat si efficiency, ce crawl a little more often from the same flasks from the pressed chick, but the last still yama and ce will refuse the si position. Those are a lot of evtiny, not a lot of sensibility and not sa sensible capriciousness in relation to the stability of the zahranvaneto.
Species socles, crawling into the spotlights
Now we’ll talk for a while for socles, which we often use in a spotlight. For a lamp from a hot chick, maybe bi-popular more like this, name the caps on Edison, which you better know for almost vsichki. They will be offered in various standard sizes, but most will cross for the E27 and E40 floodlights.

Use the equipment with a relatively low power (up to 500 W) from the light source, the last use for the power of the device (up to 2 kW or more).
What is it about to halogenite from the sources on light, togawa, take it apart, nay-chest cross based on more basic R7sI used it in a linear halogen lamp behind a spotlight. Even though it is double, this lamp is directed under the format for a long time, and contact the wearer on the current at the edge.

Another widely used base is based on G5.3 (MR16). I crawled out in miniature, but enough power to soak up the light from the source.

How to get rid of the belly on the crush
Light a lot of times from a hot spot and especially halogenite from the source to the bright line will burn out, without a hitch, they worked half a half from the announcement period.And the reason for this is not the low quality of the product, but the difficult working conditions. The main problems that cause damage to the lampat, such as switching on / off and overvoltage.
Frequently included
Sigourno ste became white, what a lot of crushes will burn out, when you turn it on. What is the reason? The student's spiral on the krushka ima deset five little resistance from the heat. At the moment when the current is turned on, it is the opposite of the law on Ohm (current \u003d voltage / resistance) and tens of five times from the nominal. Szdava t. Nar. The currents blow, some of the spiral from the fire.
How can we get out of the situation? Do not turn off the searchlights day and night? Generally not necessary. Sufficient food and equipment with lighting devices with a special block - devices for smoothly turning on the lamp (UPVL)
Device for smoothly switching on a lamp with a power of up to 1 kW
When the coil is turned on, such a device smoothly increases the voltage on the spiral from zero to nominal, which allows it to flood evenly and eliminate the current shock. Such devices work well with both halogen lamps, and with conventional lamps with a hot plug. E, the diagram for turning on the spotlights prez UPVL is still below:
Schematic for turning on the spotlights through UPVL
Tension to tension
When switching on / off on power, consumers in the tyahnat of protecting the media will inevitably rise to a high voltage. Ako spotlight sa svyarzani kamna and sya line, togava tsyalata tazi “beauty” otiva at tyah, and crashes, sort it out, they won’t spend it on work mode. Dealing with tosi is a rather difficult type of problem. There are two possibilities here:
- “Put” spotlights on another electrical conduit.
- Use overvoltage protection.
The preferred option is optimal, but it is most impossible and even put into practice - the electrical conductor is usually the same and is switched from phase to phase nyama and in the direction of the bottom, this way the power of the product is usually three-phase and creating embarrassment on trite phase.
The second option is e a lot of skjp and not vinagi is effective - if you get enough pressure, then gava nito is one passive filter nyama and sing, and more actively there are tens of five by -skjp from the projector itself.
But ima and third option. That one is not nay - “beautiful”, but it is very effective and it’s literally a stotinka. Ako turn on the diode in series from the spotlight, then the effective voltage on the lamp is half as low, which means that chedori nai-strong jump yama and increase the nominal voltage on the lamp.
But there is only one "but". Thy kato working tension is painted, the lampata is still burning in a weak way. But if the lamp in the spotlight burns out constantly, it’s not a commodity, but it’s an option. In the extreme case, you can put more power on the top, to compensate for the decrease in brightness. The schematic for connecting to the searchlight of the pre-diode is as follows:
Schematic for switching on the spotlight pres diode
In this case, it is not necessary to keep track of the polarity on the inclusion of a diode - there is absolutely no difference in the anode and in the cathode.
Such a thing is a good idea to cross the lamps behind the spotlights. Now you know which ones from tyah ce spolzvat honestly, expand the technical characteristics and, if necessary, you can protect the device from chastity from harm.
