Why LED lighting? From:http://www.lgiled.com   Reporter:   Date:2012/8/20 17:28:56   Tags:led-panel-light-price high-power-led-bulbs led-bulbs-wholesale

    When I began working on LED, few people knew what it was, but on the other hand very few even knew what a personal computer was, since it was 1980, basically the prehistory of the information age. Today everyone knows what a PC is, but only a few know what an LED is; yet the monitor of a PC, the keys and the display on mobile phones, the dashboard of an automobile are lit by LED. In this presentation we would like to give a brief illustration of what a LED is and what ca be done with this component.

    Technically the name is an acronym, which stands for "Light Emitting Diode". It essentially relates to a small component invented in 1962 that illuminates when an electric current, not through filament which must reach extremely high temperatures to produce light; the temperature of the LED is only 50-60°C and it is very important that this temperature not be exceeded, but we will talk about this later.

    To get back to the history of the LED, in 1970 the only colour available was red and the light emitted was very faint, essentially much less than 1 lumen; if we consider that a common light bulb has a brightness of at least 500 lumen, it was unthinkable to use it for lighting. LEDs have made some progress since then, first with the arrival of yellow and orange LED, then green and finally in the early 1990''s the arrival of the "legendary" blue LED, pursued from many years by designers and builders. The arrival of blue gave a big boost to LED market since, with red and green, it can be used to reproduce RGB pixel to create large video screens; furthermore, right combination of these three colours gives white light.

    In the meantime, the brightness has also increased considerably and by the end of the 1990s a pixel made up of three LEDs had a white brightness that exceeded 2 candelas. During this period, the white light single LED appeared, which was derived from the blue LED. to the substantial development of this LED, where it is used to illuminate the screen and the keys. The expanding market created competition and spurred research to the point where the white LED began being used for interior lighting even if, up until 2006, it was mainly used for scenographic lighting. The reduction in costs and the increase in light output are therefore making it the lighting of the future. Many years have past since 1980 and we have used LEDs to build sign panels; road information panels; traffic lights; display for buses, trains, train stations and airports; 300 m2 maxi screens and giant video screens and today we produce display screens for sport stadium advertising at a rate of 100 m2 per week, using millions and millions of LEDs. We haven't forgotten about lighting, which we see as our future, but we were also pioneers. The first LED lighting project dates back to 1996 and served then (and still today) as back-lighting for road signs; only now however is this technology mature enough for use in proper lighting; to eliminate light bulbs that consume too much energy, that burn out, that burn the skin, that get consumed.

    It's true that there are the new energy saving light bulbs, but they are as ugly as the light they emit! LED is another thing, another world. LED consumes very little energy, and its efficiency is by now even better than those of energy saving light bulbs. LED has a very long life of over 50,000 hours, so if it is used 5 hours a day it will last almost 30 years.

    In any case, it will not ''burn out'', it will just stop operating, therefore zero maintenance and zero disadvantages. LED produces a pleasant light and is available in many tones, for the office, home, shop. The LED is colour; no light bulb can simultaneously give all the desired colours, LED gives thousands of colours. For the garden; swimming pool; bathroom; shower; bedroom; basement; portico;shop windows; things that are impossible whit other forms of lighting. LED is expensive.... It''s true!a LED light bulb costs more than an incandescent or neon light bulb, but when we consider the energy savings and maintenance, we have often already met the equilibrium, but then if we consider design, colours, functionality, the scale begins to clearly tip towards LED, which over time will lean even more.
