Menene attenuation haske LED?
Hasken haske na LED yana nufin hasken haske na LED zai zama ƙasa fiye da ainihin hasken haske bayan hasken wuta, kuma ƙananan ɓangaren shine hasken haske na LED. Gabaɗaya, masana'antun fakitin LED suna yin gwajin a ƙarƙashin yanayin dakin gwaje-gwaje (a yanayin zafi na al'ada na 25 ° C), kuma suna ci gaba da haskaka LED tare da ikon DC na 20MA na sa'o'i 1000 don kwatanta ƙarfin hasken kafin da kuma bayan an kunna hasken. .
Hanyar lissafi na attenuation haske
N-hour haske attenuation = 1- (N-hour haske juyi / 0-hour haske juyi)
Hasken hasken ledojin da kamfanoni daban-daban ke samarwa ya sha bamban, sannan manyan LEDs suma za su samu raguwar haske, kuma suna da alaka kai tsaye da yanayin zafi, wanda galibi ya danganta ne da guntu, phosphor da fasahar marufi. Ƙwararren haske na LEDs (ciki har da ƙwanƙwasa mai haske, canjin launi, da dai sauransu) ma'auni ne na ingancin LED, kuma yana da matukar damuwa ga yawancin masana'antun LED da masu amfani da LED.
