Ni ukubera iki urumuri rwumuhanda LED ari rwo rwiza rwiza rwimvura nigihu?

Ibicu no kwiyuhagira birasanzwe. Muri ibi bihe bitagaragara neza, gutwara cyangwa kugenda mumuhanda birashobora kugora abashoferi nabanyamaguru, ariko tekinoroji ya LED yo kumurika kijyambere itanga abagenzi ingendo nziza.

Itara ryumuhandani isoko ikomeye-yumucyo ukonje, ifite ibiranga kurengera ibidukikije, nta mwanda uhari, gukoresha ingufu nke, gukora neza cyane, no kuramba. Kubwibyo, urumuri rwumuhanda LED ruzahinduka uburyo bwiza bwo kuvugurura ingufu zo kuvugurura amatara yo kumuhanda. LED itara ryumuhanda nigikorwa cyinshi-cyumucyo utanga urumuri rushingiye kuri semiconductor pn ihuza, ishobora gusohora urumuri nimbaraga nke zamashanyarazi. Munsi ya bias nziza ya voltage hamwe ninshinge zatewe, umwobo winjiye muri p-karere na electron zatewe muri n-karere zikwirakwira mukarere gakora nyuma yo kwisubiramo imirasire no gusohora fotone, bigahindura ingufu z'amashanyarazi ingufu zoroheje.

Ibyiza byumucyo wumuhanda LED mubicu nimvura birashobora kugaragara mubice bitatu:

1. Icyerekezo cyihariye cyumucyo wasohotse;

2. Ibiranga uburebure bwa LED yera;

3. Inshuro zubu burebure ugereranije nandi masoko yumucyo.

Itandukaniro riri hagati yamatara ya LED nandi masoko yose yumucyo nuburebure bwiganjemo umurongo wohereza ingufu, nuburyo ibitonyanga byamazi bikora cyangwa bigira ingaruka kumurongo kuri ubwo burebure, cyane cyane uko ubunini bwibitonyanga byamazi bihinduka.

Inkomoko yumucyo isohora ingufu zumucyo muburebure bwubururu bwubururu bugaragara, nka LED, ikora neza kurusha andi masoko yumucyo mubihe bitagaragara.

Umucyo mukarere ka violet murwego rwikigereranyo ufite uburebure bwumuraba mugufi kuruta urumuri mukarere gatukura. Ibice by'amazi biva mu kirere ubusanzwe bitanga urumuri mu muhondo-orange-umutuku, ariko bikunda gusasa urumuri rw'ubururu. Ibi birashobora guterwa nuko ibice byamazi bisa nuburebure bwubururu. Kubwibyo, iyo ikirere kiboneye nyuma yimvura cyangwa ikirere kiboneye mugihe cyizuba (hari uduce duto duto duto mu kirere, cyane cyane gukwirakwiza molekile), munsi yingaruka zikomeye zo gukwirakwiza molekile zo mu kirere, urumuri rwubururu runyanyagiye kugirango rwuzuze ikirere, n'ijuru bigaragara ubururu. Iyi phenomenon izwi nka Rayleigh ikwirakwiza.

Mugihe kigaragara neza, ibice byamazi byiyongera mubunini kugeza aho bitakigaragara mubunini nuburebure bwurumuri rwubururu. Kuri iyi ngingo, baragereranya mubunini nuburebure bwumuhondo-orange-umutuku. Ibice by'amazi bikunda gutatana no guhagarika urumuri muriyi bande, ariko bikanyura urumuri rwubururu. Niyo mpamvu urumuri rw'izuba rushobora rimwe na rimwe kugaragara nk'ubururu cyangwa icyatsi kubera igihu.

Kuva mubunini bwamazi kugeza kumuraba, amatara yo kumuhanda LED niyo mahitamo meza kubintu bitagaragara. Ubushyuhe bwamabara hamwe nigishushanyo cyerekana imiterere yumuhanda mugihe cyimvura nigihu. Mugutezimbere kugaragara, amatara yumuhanda LED atuma imihanda igira umutekano mugihe cyimvura n’ibidukikije.

Niba ushishikajwe no kumurika umuhanda LED, urakaza neza kuri LED umuhanda ukora urumuri TIANXIANG kurisoma byinshi.
