How To Make High-efficiency Led Lighting

LED one of the protagonists of this new technological era and the ever-increasing push for ‘energy efficiency.

We are in the midst of an industrial revolution, technology is chasing itself, so fast is it. In the field of lighting, we are witnessing a development oriented to lower consumption and maximum efficiency, with an eye also to ‘aesthetics.

Led lights, led lamps, led spotlights and led strips today are essential for the ‘lighting of our environments, they are also spreading for outdoor lighting and street ilumination, although on this point the convenience is not as marked, as it is presented, but this is another topic, which deserves a separate discussion.

THE LED in brief.
The Light Emitting Diode (hence the acronym LED) while not a baby, having been spawned by the father of high-efficiency LED lighting, physicist Nick Holonyak Jr back in 1962, at that time a consultant to General Electric, its development as a source of illumination began in the 1990s, with the production of Light Emitting Diodes of various colors. Neel 1995 began the production of the white-emitting LED, thus laying the foundation for high energy and light efficiency, which is still evolving today.

Prior to the 1990s the use of this light source, which was only red in color was relegated to use as a signal light in electronic boards or segment displays to form numbers letters, etc.
led basic colorsThe advent of the third millennium also brings rapid development of the output and thus the energy efficiency of Light Emitting Diodes, bringing it to very high levels, greatly improving the luminous flux per watt of power consumed, as well as the color rendering index CRI Ra and the correlated color temperature indicated in Kelvin, all aspects of which photometry deals with.
In 2014, three scientists belonging to a study team formed by the collaboration between Nagoya University and the University of California, Santa Barbara were awarded the Nobel Prize in Physics .

Fields of use of LEDs.
LEDs in lighting engineering, nowadays are used in every field where ‘efficient, economical and environmentally friendly lighting is required. LEDs in addition to consuming much less and thus requiring less energy production at the source, resulting in less impact on the environment. As a result little energy dissipation. In addition, they have a very high durability when compared to other types of lamps such as fluorescent lamps ( until yesterday considered the top saving lamps).
