Summary:

The LEDs (light emitting diodes) have been a revolution in the world of lighting and can now create lighting effects unthinkable years ago. Since a quarter of the world's electricity is used for lighting, you can imagine the impact of this invention, Isamu Akasaki whose creators, Shuji Nakamura Hiroshi Amano and were awarded this year's Nobel Prize in Physics.

It is a relatively new compared to other years leading product in the market. We will evaluate performance in order to understand why it will become certainly none in the most widely used in the imminent future.

Advantage

  • Economic are extremely efficient and allow savings between 60 and 90% compared to conventional lamps, and between 10 and 20% compared to the energy saving lamps. This coupled with long life of over 50,000 hours ago that saving energy saving is remarkable.
  • Environmental Benefits produce minimal heat, do not contain toxic composition which lowers recycling.
  • Intelligent lighting systems greater control of regulation for dynamic lighting applications such as RGB, wide color gamut with saturated colors without filters, and extensive possibilities for innovative designs.
  • Instant start not require delay to achieve optimal lighting.
  • Low energy requirement so they can be powered by solar and cheap energy can increase the quality of life of populations that lack access to electricity networks.

Disadvantages

  • High prices although the cost continues to decline, its price remains significantly higher than traditional lamps
  • Wide market LED manufacturers market is growing, and there are many qualities and characteristics that the choice is difficult if not have technical knowledge.
  • Poor performance at high temperatures Led mounts need good heat dissipation to avoid producing a reduction of its life.

Noting the significant reduction in consumption and low maintenance based on the durability of the lamps, you could say "incandescent bulbs illuminated the twentieth century and the LED lamps illuminate the XXI Century"
