The human body very needs air and water. But also the person needs natural lighting without which there will be no elementary comfort and cosiness. Thanks to the intelligence, society could pass hard way from candle to modern LED lamps.
Technologies of the future
The modern market of the lighting equipment offers the broadest choice of lighting various. There has passed that time when to ordinary bulb of Ilyich there was no alternative, and people instead of good lighting, received lot of heat which was generated by such lamp and not enough light which was radiated after all by this device. Today producers of lighting equipment can please the clients with great choice for every taste. From all applied technologies in lighting today especially there is a wish to note lamps with application of LEDs and optical fibers. These products do not enjoy wide popularity owing to the high cost and uncertainty. But behind such technologies the future.
Types of lamps
Naturally, the lamp of Ilyich will be the very first lamp which it is worth mentioning. In this invention as the main vital energy serves tungsten thread which not just shone, but also was great heated. Such bulb has the efficiency of 5%. And to all this, its resource is too small, the only plus is low cost. But nevertheless, thanks to warm shade of emitted light, such lamps create certain warm atmosphere indoors.
The following sample is lamp of halogen type. It has more long term of operation than its progenitress. The technology of such lamp is similar previous, the method of protection of thread against premature evaporation by means of gases of halogens is applied only here. These gases considerably lift resource of such lamps and give significantly bigger efficiency. The halogen bulb gives very bright light similar to day. Lamps of the next generation are luminescent. It is the most real break in lighting, similar devices several times consume electricity less, at the same time several times brighter shine, than the previous samples. Such lamps very economic that it is important for fire safety, are not heated, however do not love low temperatures. Well and the leader in all indicators there will be LED lamp. In similar inventions technologies passing of electricity via the small special chip are applied, and thus light turns out. Tension which is necessary for the diode - only 12 V. Srok for operation just improbable plus these lamps are practically not heated. The LED can give any shade of luminescence. For today it is the best prospect of cosiness, reliability and economy. It should be noted also that in the market of lighting it is possible to get on huge number of the "left" China. Therefore it is necessary to pay attention to producers with good history. In particular, such marks as Philips, Pila, Osram, General Electric, Maxus are those brands which manufacture products of the European level. Their quality and the price policy it is justified for all 100%. Let the products of these brands be more expensive than basement China, but it is more justified and paid back.
