Interesting facts about LEDs will allow you to take a fresh look at the alreadyfamiliar lighting technology, which most recently belonged to the field of sciencefiction. We have collected for you the most interesting of the history of LEDs toappreciate all their advantages and features.
The first full-featured LED was created by Nick Holonyak in 1962, laying thefoundation for the production of lighting equipment based on semiconductormaterials. Despite the fact that LEDs are now fairly inexpensive until 1968, until thepossibility of their serial production was discovered, the cost of one copy was atleast $ 200
LEDs are the most common technology compared to other light sources. Theyare used for the manufacture of lighting lamps, indicators of household appliances,in flashlights, backlight systems and camera flashes – at your place, there willprobably be more than a dozen LEDs of various kinds. The technology for producingcrystals for LEDs is very complex and expensive, only a few countries can affordtheir production, and more than 50% of the LED products market is made up ofsupplies from China;
LED is the most durable light source among other analogues. The averagelifespan of a heavy duty LED is 50,000 hours. If the light bulb burns for days, then itwill be enough for almost 6 years of continuous operation. There are LEDs in variouscolors, the shade of light depends on the type of semiconductor materials used, andnot at all on the color of the external lens. LEDs are resistant to shock and vibration,since the semiconductor element and thin wiring are reliably protected and arelocated in the housing of the plastic lens. That is why the LEDs are optimal for usein flashlights, work equipment and other devices.
LEDs are the most economical source of light; a lamp with a power of 5W interms of luminous flux power is comparable to a lamp of 100W. In the manufactureof lighting lamps, both separate powerful LEDs and assemblies of medium powerelements in a single housing are used. More information about LED lamps can befound here;
The assembly of three miniature LEDs of red, green and blue, allows you toreproduce any color when mixing the spectrum using a special lens. Suchassemblies are used in TV backlight systems, in advertising designs, etc.
LED technology is being actively developed. More and more powerful andmultifunctional models appear, and their cost is regularly reduced. There are stillmany discoveries in the future and the number of interesting facts will onlyincrease.
