  • LEDs Light-emitting diodes
  • LEDs have the advantages of high brightness, low power consumption, and long life. They have high luminous visibility and can be seen by the naked eye, but they do not have the illumination required for illumination. At present, although there are concentrating light-emitting diodes, the spot is only a small dot.

Abstract

La présente invention concerne une lampe d’éclairage comprenant au moins une diode électroluminescente et une feuille réfléchissante disposée en face de la diode. La présente invention permet d’obtenir ainsi l’éclairement requis. Elle peut utiliser la lumière du jour et économiser l’énergie, et elle offre un faisceau lumineux diffus, une structure simple et une longue durée. La diode électroluminescente présente une durée de vie naturelle d’environ 50 000 heures en utilisation normale. Les autres types de source lumineuse ne peuvent pas offrir de telles caractéristiques. Cette lampe d’éclairage s’avère particulièrement adaptée aux zones montagneuses et de pâturage où une énergie non polluante et solaire est utilisée.
