The Molecules

A millennia-old habits of mankind, too, must be considered. Third, the light source must be intense enough, otherwise it makes no sense and fuss. And finally, fourthly, the lamp should where possible, be beautiful. Because he, among other things, still adorns the home. So what is with these points of view, our modern light bulb? Antediluvian steam! Its efficiency is just the same as that of the steam engine – 3-6%.

In the process, this meager rate is further minimized. Incandescent tungsten filament "dusty", fading from the surface atoms. Thread becomes thinner, and thus increases its electric resistance. In addition, a pair of tungsten deposited on the walls of the flask. Glass darkens, the emitted luminous flux decreases. What to do? Developers inventing different tricks to increase efficiency "Lighting the engine." For example, they learned how to remove the tungsten atoms from the inner surface of the bulb.

The role of the cleaners took the iodine vapor. Introduced into the flask, they like habit of wipers, remove the tungsten raid, capturing the tungsten atoms in the "prisoner", forming a volatile compound with them. Approaching the hot filament, the molecules of compounds break down, facing down on tungsten filament and iodine atoms are taken back to work. Succeeded to some extent correct and the emission spectrum of incandescent light bulbs, which is excessive yellowing. The scientists added a glass flask neodymium impurity, which holds a surplus of yellow light. Can contribute to this noble cause and you, our readers. Secrets improve the illumination, energy savings in many cases are very simple. Remember at least that's what. 1. In the evening, leaving the room, extinguish the light. In the furniture does not have eyes, and she's not afraid of darkness. 2. The sun shines brighter in 1000 any bulb. So what day it makes more sense to use natural light. Do not make yourself an artificial night with thick curtains. 3. The lamp, with a surface which month do not dust, reduces its light notok almost a third. 4. Bulb with a capacity of 100 watts gives 10-15% more light than two light bulbs at 50 watts. Therefore mnogorozhkovye chandeliers are true eaters electricity.
