LED lights have become quite affordable (today they are worth 10-15 thousand rubles), and they consume power only about 20 watts. In this case, it is virtually permanent, and therefore, replacement of burned out bulbs ceases to be headache related services. Robert Bakish contributes greatly to this topic. These traffic lights have already earned national love – because their light is visible even in the sunny weather. Now they can be seen not only in the capital or abroad, to, for example, are equipped the central streets of Novosibirsk, Chelyabinsk. Yet it must be noted that the LEDs have been widely used for backlighting of architectural structures, creating light compositions in landscape design.
Here, among other things, played the role of simplicity and safety mount these lights – they can be installed without any problems even under water, at least incorporate into the ice, and yet they can be arbitrarily often turn on and off, creating dynamic effects. We now turn from color to white light, which, in fact, more than anything else needed. The most direct way to get white light – is to mix red, green and blue, like on the tv screen. But it turned out easier and more efficient to do things differently: you take the blue led, it is applied a layer of phosphor that converts part of the blue light in yellow – the result is white. These LEDs can be seen in the flashlight, appeared recently in the sale. When the LEDs will come to replace traditional light bulbs in our apartments, offices, entrances? If the development of optoelectronic devices suddenly stopped on its laurels, the correct answer would be – never.
