LED light bulbs are a worthy alternative to incandescent lamps, they have advantages in comparison with those bulbs that we used to use in our daily life. First of all it is worth noting that LED light bulbs have a longer service life, on average 10 years (incandescent lamp works on average 3-4 months), in addition, there is a significant energy saving (LED - 10W, incandescent lamp - 75W) and not it is worth forgetting about the ecological side. But the cost of LED bulbs significantly exceeds the price of conventional or energy-saving light bulbs, so most consumers refuse to use them and choose energy-saving or conventional incandescent lamps.
At the University of Florida, scientists have announced a revolutionary method of manufacturing LEDs, which will make the cost of such light bulbs much smaller, and therefore more affordable.
If the price of LED and incandescent bulbs becomes the same, then the latter, most likely, just disappear from our lives.
Florida scientists noted that the new manufacturing method assumes one layer, instead of 4-5 layers, which are used in modern light-emitting diodes. The application of a combined organic / inorganic material into a single layer will allow the LED light bulb to maintain its efficiency, but will make its price much lower. In addition, to date, the application of layers requires high temperatures, according to a new method, this can be done at ordinary temperature.
It should be noted that the researchers have long been using this material (about 3 years), for some time the material was already used for manufacturing solar panels, but the group of Professor Zhbin Yu was the first to use this material for manufacturing single-layer LEDs.
The traditional technology of manufacturing the LED lamp involves processing at high temperatures and expensive substrates to achieve high power, all this and caused a high price of the LED light bulb.
The first organic LED light bulbs (OLED) were processed in one layer at low temperatures, but several layers were gradually added and amorphous silicon substrates were used, which increased the efficiency, as well as the price of the finished product.
Professor Zhibin together with his colleague Junkyang Lee state that the new method of producing LEDs, developed by them, will become a real scientific breakthrough. To fabricate the LED, an organometallic halide of the primite will be required, which can be applied at normal room temperature, while the cheapest glass substrates can be used. The fastening of the layer occurs only at 600 ° C.
Also, researchers noted that to create a structure it would be necessary to combine an organic and active inorganic polymer, which would replace the complex process of obtaining a multilayer structure. As a result, the production process is much lower in cost and is rather technological.
In their article, a team of specialists claims that their technology will make LED fixtures more affordable at the expense of reducing the layers.
