Isesengura ryibitera LED kwangirika
Nubwoko bushya bwamatara yicyatsi, amatara ya LED azigama ingufu, yangiza ibidukikije kandi aramba. Isoko rishobora kuba rinini. Nyamara, ikibazo cyo kwangirika kwurumuri rwa LED nikindi kibazo amatara ya LED agomba guhura nayo. Umucyo udahwema kubora, bigira ingaruka zikomeye kumikoreshereze yamatara ya LED.
Kugeza ubu, kwangirika kwinshi kwa LED yera ku isoko birashobora kuba kimwe mubibazo byingenzi kumurika abasivili. Muri rusange, hari ibintu bibiri byingenzi bitera kwangirika kwurumuri rwa LED:
Ubwa mberely, ubwiza bwibicuruzwa LED ubwabyo:
1. Chip ya LED yakoreshejwe ntabwo ari nziza, kandi umucyo uhinduka vuba.
2, uburyo bwo kubyaza umusaruro bufite inenge, ubushyuhe bwa LED ntibushobora koherezwa neza mumashanyarazi, bikavamo ubushyuhe bwinshi bwa chip ya LED kugirango chip yiyongere.
Icya kabirily, twekuriibisabwa:
1. LED itwarwa numuyoboro uhoraho, kandi LED zimwe na zimwe ziyobowe na voltage kugirango LED ihuze.
2. Imiyoboro ya drake irarenze imiterere yagenwe.
Mubyukuri, hariho impamvu nyinshi zo kwangirika kwumucyo wibicuruzwa bya LED. Ikibazo gikomeye cyane nikibazo gishyushye. Nubwo abayikora benshi batita cyane ku gukwirakwiza ubushyuhe mu bicuruzwa bya kabiri, gukoresha igihe kirekire ibyo bicuruzwa bya kabiri bya LED bizaba bifite urumuri rworoshye. Gukonjesha LED ibicuruzwa bigomba kuba hejuru. Kurwanya ubushyuhe bwa LED chip ubwayo ningaruka zo gukwirakwiza ubushyuhe bwa substrate nabyo bifitanye isano no kwangirika kwumucyo.
Ingaruka eshatu LED Itara ryiza ryumucyo
Mbere ya byose, guhitamo amasaro ya LED.
Ubwiza bwamatara ya LED burashobora kuvugwa ko ari ikintu gikomeye. LED chip ya tekinoroji itandukanye itanga umusaruro ifite umuvuduko utandukanye wo kubora. Kurugero, ababikora benshi ntibagura amasaro yumwimerere yatumijwe hanze. OAK igura amasaro yumwimerere yabanyamerika CREE LED. Muri rusange tekinoroji yo gupakira irarenze ayandi matara ya LED munganda imwe, ifite ibyiza byinshi mumikorere yumucyo no kurwanya ubushyuhe bwinshi.
Icya kabirily, itara rya LEDgukoraubushyuhe.
Dukurikije amakuru ya CREE LED itara ryashaje, mugihe itara rya LED rikora, ubushyuhe bwibidukikije ni dogere 30, hanyuma ubushyuhe bwo gukora bwurumuri rumwe rwa LED ni dogere 60-70. Nubushyuhe bwiza bwakazi bwo gukoresha igihe kirekire.
LED itinya ubushyuhe, nubushyuhe bwo hejuru bwamatara ya LED, nigihe gito ubuzima bwa LED, nubushyuhe bwubushyuhe bwamatara ya LED, nubuzima bwa LED. Kubwibyo, mugihe dushushanya luminaire, imikorere yo gutwara ubushyuhe no gukwirakwiza ubushyuhe byongerwa kugirango ubuzima bwitara rya LED.
Icya gatatu, amashanyarazi akora yamashanyarazi ya LED yamashanyarazi yarateguwe.
Ukurikije ubushakashatsi, uko munsi yumuriro wamatara ya LED, niko ubushyuhe bwasohokaga, nubucyo bukaba buto.
Muri make , igishushanyo mbonera cyibikoresho byamashanyarazi bikora kumatara ya LED bigomba kuba bishingiye kumiterere nyayo. Niba ibikorwa byo gutwara ubushyuhe no gukwirakwiza ubushyuhe bwitara ari byiza cyane, ubushyuhe buterwa nigikorwa cy itara rya LED burashobora koherezwa hanze hanze nta kwangiza LED.
