All about the 200W incandescent lamp

Despite the fact that the “ancient” Ilyich bulbs were replaced by more economical ones - diode and other analogues, incandescent bulbs still remain popular and in demand among modern consumers. These products have both pros and cons. One of the most popular are 200W incandescent lamps. Why this is happening, let's try to figure it out in this article.

What is a light bulb?

Most of the interior of a 200W incandescent lamp can be seen through its transparent bulb. The main components of the device are electrodes that feed a thread of refractory tungsten metal stretched between them. So that the fragile tungsten filament does not break when transporting the device, it is supported by holders (supports) made of molybdenum. All electrodes and holders converge to the middle and to the base, where they are interlocked with bimetallic wire and soldered into a glass frame extending to the base.

Further we can not see behind the base cover, but nothinginteresting and magical there. The plus is output and energized with the middle contact soldering, the minus contacts with the circular rim of the base, made in the form of a thread so that the light bulb can be screwed into the socket.

Operation principle

The 200W incandescent bulb works like all appliances that are heated by incandescence. They are irons, heaters, hair dryers, soldering irons and other appliances. There, metals other in composition are used for heating, with the required level of resistance. Tungsten, on the other hand, has a very high resistance. It is it that does not allow a sufficiently small thread to melt and collapse when a voltage of 220 volts is applied to it. It only heats up to such an extent that it is simply impossible to look at it with the naked eye for a long time. It is the glow of this white-hot thread that emits light comparable to a huge number of lit candles.

Tungsten twists

But we know from chemistry lessons that if tungsten is heated to a temperature of 3000 degrees (this is the temperature of the filament in a working device), it will simply begin to oxidize, due to which the filament will break. Therefore, in the internal cavity of the flask of 200 W incandescent lamps, as well as in similar products of other ratings, either there is no air at all (vacuum reigns), or it is replaced in it with an inert gas, with molecules of which tungsten does not react when heated.

Pluses of incandescent bulbs

The most obvious advantages of such light generating devices are:

• verylow cost;
• ability to function normally under any temperature fluctuations and atmospheric humidity;
• the ability of such a light bulb to generate heat, which is also important in some circumstances;
• ability to withstand minor power surges;
• does not emit hazardous gases into the atmosphere when broken;
• do not require special disposal measures.

Cons of incandescent bulbs

They are there too. And the main disadvantages of 200W incandescent lamps are:

• Comparative fragility, since the warranty working life of such devices is limited to 1000 hours at 220V and 2500 hours at 127V.
• A fragile flask that is damaged by the slightest impact on any hard object.
• Perceptibly higher power consumption compared to energy-saving counterparts.

Conclusion

There are incandescent lamps with E14 and E27 sockets. Also, products differ in power. The most popular models are 60, 100, 150 and 200 watts. What to buy, a 60 W E27 incandescent lamp for 20 rubles with a resource of 1000 hours, or its diode counterpart, the cost of which exceeds 2000 rubles, but with a resource of 40,000 hours? The choice, again, is yours!
