Did you know that it is very difficult that a led to burn? Did you know that at the beginning of its short existence, led emitted a little intense light? Do you know that it was until the 1970s? s carried various combinations of materials that allowed other colors, in addition to the classic red? Leds, these lower-case lights that we can find in every home or business, on the remote control or in an electronic device, had their origin in the years 60s, when it was marketed using gallium, arsenic and phosphorus (GAsP) with which got a red led. In the 70s years, combining other materials is managed to broaden the spectrum of colours such as green, amber, orange and red. In the 80? s a new material illuminated the stage, joining thus gallium, aluminium and arsenic, which allowed a greater brightness compared with the previous ones, in addition to working at high currents. However, its durability with moisture and high tempraturas be more degraded. In the years do 90? s, appears the best mix created for this type of products: aluminium, indium, gallium and phosphorus. The best, the wide range of colors that can be achieved, and its extensive life: up to 100,000 hrs. in an environment of high temperature and humidity. Seeing the above, we can deduce that achieve a led to burn is very difficult.
The most that can happen is to make a short or open. The leds are now used in luminous announcements, remote controls, electronic devices in any sphere, machinery, lights, vehicles and many more. Long life to the small leds. Jose Ignacio Gutierrez Palacios original author and source of the article
