WHAT IS AN LED?

Almost all of us have sometime heard talk about or seen an LED, for example, as a blinking light in our TV. LED stands for Light Emitting Diode, and it is a source of generation of light that is developed through materials and technologies used in the manufacturing processes of electronic chips..

HOW HAVE LEDs EVOLVED?

LEDs have progressed a lot since the appearance of first red LEDs in the 60´s, passing through red LEDs in the 70´s. The appearance of red LEDs in the early 90´s brought about the possibility of creating white light through LED technology. However, all of these types of LED had a common disadvantage: the lighting power was very low, which limited their application to just signalling purposes.

Thanks to the fast advance of the different electronic technologies and of generation of semiconductors, the creation of LEDs with capacity to generate light took place in the late 90´s. For this reason, these LEDs were denominated “high power LEDs”.
