En aquest Treball de Recerca s\u2019ha investigat les propietats f\u00edsiques dels d\u00edodes emissors de llum o LED, un invent que ha revolucionat la forma d\u2019il\u00b7luminar els habitatges del m\u00f3n. L\u2019estudi s\u2019ha enfocat en tres propietats com s\u00f3n la relaci\u00f3 entre la intensitat de corrent amb la caiguda de tensi\u00f3 dels el\u00e8ctrodes dels LED; la relaci\u00f3 entre la il\u00b7luminaci\u00f3 d\u2019un LED i la pot\u00e8ncia dissipada i finalment la relaci\u00f3 entre la il\u00b7luminaci\u00f3 d\u2019un LED i l\u2019angle de visi\u00f3. L\u2019estudi d\u2019aquestes propietats \u00e9s determinant en el camp de l\u2019electr\u00f2nica i en l\u2019optimitzaci\u00f3 de la il\u00b7luminaci\u00f3.\u00a0<\/p>\n

La metodologia ha consistit en un circuit el\u00e8ctric amb una font d\u2019alimentaci\u00f3 de corrent continua, una placa d\u2019electr\u00f2nica, una resist\u00e8ncia protectora en s\u00e8rie i el LED.<\/p>\n

Els resultants obtinguts mostren que en les condicions experimentals de treball la intensitat que passa pel circuit segueix la funci\u00f3 exponencial ja descrita amb anterioritat; que la il\u00b7luminaci\u00f3 del LED creix a mesura que creix la pot\u00e8ncia dissipada, per\u00f2 que el seu creixement s\u2019alenteix per a pot\u00e8ncies superiors; i que la il\u00b7luminaci\u00f3 del LED baixa a mesura que l\u2019angle s\u2019allunya de la normal amb molt poca llum a partir dels 30\u00ba. Aquestes propietats s\u00f3n determinants per calcular la despesa energ\u00e8tica \u00f2ptima i la forma d’il\u00b7luminar amb els LED m\u00e9s correcta.<\/p>\n
