How do bulbs work?

Standard bulbs of bulbs work in essentially the same way as today at the time of its invention more than a hundred years ago. Thomas Edison is generally attributed by the invention of the bulb in 1879, although Sir Joseph Swan from England arrived at the idea of ​​1878. Many inventors of that time tried to create a light source that replaced candles and oil lamps that were not only dangerous but dirty. At the turn of the century, millions of households replaced fire and oil with a modest electric bulb. However, not all photons emit visible light. In fact, because of the way the bulbs functioning, most of the radiation is emitted as a heat rather than a visible light. For this reason, bulbs are not very effective light generators according to today's standards. Two metal rods Extend up to the chamber from contacts at the base of the bulb. The rods connect the tungsten thread. Wolfram is a key element of the way the bulbs work because it has a very high melting temperature. When electricity is applied to the bulb, the accounts passKty, rods and connecting thread, exciting atoms in tungsten, which generate photons.

atoms excited vibrate. Over time, the tungsten fiber weakens when individual atoms vibrate without a fiber. This is an area where one improvement has been made in the way the bulbs work. The bulbs originally did not contain inert gases, but a vacuum that did nothing to prevent the loss of atoms. The inert gases help to prolong the life of the fiber by providing the “bumper” atoms that help bring the atoms back into the thread when they escape. The way the bulbs now work is a little more efficient than the original vacuum dear.

fluorescent lights have a different design that is more efficient than the way the bulbs work. Electricity charges the mercury pair inside the tubular bulb, which in turn excites phosphorus atoms that emit white light. Fluorescent lights run colder, take less energy and hold onIt is longer than the bulbs. However, some people consider fluorescent lighting harsh. Flashing fluorescent lighting can also potentially cause attacks in epileptics.
