Y\u00fcksek g\u00fc\u00e7l\u00fc LED’ler (I\u015f\u0131k Yayan Diyotlar), enerji verimlilikleri ve uzun \u00f6m\u00fcrleri sayesinde ayd\u0131nlatma end\u00fcstrisindeki devrim niteli\u011findeki geli\u015fmelerden biridir. Ancak, bu LED’lerin etkin \u00e7al\u0131\u015fabilmesi i\u00e7in uygun \u0131s\u0131 da\u011f\u0131l\u0131m\u0131 sa\u011flamak son derece \u00f6nemlidir.
