Kuki urumuri rwa LED ari rwo mahitamo meza mu gihe cy'imvura n'ibihu?

Igihu n'imvura ni ibisanzwe. Muri ibi bihe bitagaragara neza, gutwara imodoka cyangwa kugenda n'amaguru mu muhanda bishobora kugora abashoferi n'abanyamaguru, ariko ikoranabuhanga rigezweho ry'amatara ya LED ririmo guha abagenzi ingendo zitekanye.

Itara rya LED ku muhandani isoko y'urumuri rukonje rwa solid-state, rufite imiterere yo kurengera ibidukikije, nta mwanda uhumanya, ingufu nke zikoreshwa, imikorere myiza y'urumuri, kandi ruramba. Kubwibyo, urumuri rwa LED ruzaba amahitamo meza yo kuvugurura amatara yo mu muhanda mu buryo bwo kuzigama ingufu. Urumuri rwa LED ni isoko y'urumuri rwa solid-state rukora neza cyane rushingiye ku ihuriro rya semiconductor pn, rushobora gutanga urumuri rufite ingufu nke z'amashanyarazi. Munsi y'umuvuduko runaka wa bias nziza n'umuvuduko wa injection, imyobo yinjizwa mu gace ka p na electron zinjizwa mu gace ka n zikwirakwira mu gace ka active nyuma yo kongera gukurura imirasire hanyuma zigasohora fotoni, zigahindura ingufu z'amashanyarazi mu buryo butaziguye. Urumuri rwa LED ni isoko y'urumuri rwa solid-state rukora neza cyane rushingiye ku ihuriro rya semiconductor pn, rushobora gutanga urumuri rufite ingufu nke z'amashanyarazi. Munsi y'umuvuduko runaka wa bias nziza n'umuvuduko wa injection, imyobo yinjizwa mu gace ka p na electron zinjizwa mu gace ka n zikwirakwira mu gace ka active nyuma yo kongera gukurura imirasire kandi zigasohora fotoni, zigahindura ingufu z'amashanyarazi mu buryo butaziguye.

Ibyiza by'urumuri rwa LED mu gihe cy'ibihu n'imvura bishobora kugaragara mu ngingo eshatu:

1. Icyerekezo cy'urumuri rusohoka;

2. Ibiranga uburebure bw'urumuri rw'amatara y'umweru;

3. Ingano y'ubu bunini bw'urumuri ugereranije n'izindi soko z'urumuri.

Itandukaniro riri hagati y'amatara ya LED n'andi masoko yose y'urumuri ni uburebure bw'umurambararo bunini butanga ingufu, n'uburyo ibitonyanga by'amazi bikorana cyangwa bigira ingaruka ku murambararo kuri ubwo burebure, cyane cyane uko ingano y'ibitonyanga by'amazi ihinduka.

Amasoko y'urumuri asohora ingufu z'urumuri mu mirasire y'ubururu bw'urumuri rugaragara, nka za LED, akora neza kurusha andi masoko y'urumuri mu bihe bitagaragara neza.

Umucyo mu gace k'umuhondo ka spectral gafite uburebure bw'umurambararo bugufi ugereranyije n'ubw'umutuku. Uduce tw'amazi mu kirere dukunze kunyura mu isanzure mu bwoko bw'umuhondo-orange-umutuku, ariko dukunda gukwirakwiza urumuri rw'ubururu. Ibi bishobora guterwa n'uko uduce tw'amazi muri rusange dusa n'uburebure bw'ubururu. Kubwibyo, iyo ikirere gikeye nyuma y'imvura cyangwa ikirere gikeye mu gihe cy'impeshyi (hari uduce duke duto mu kirere, cyane cyane dukwirakwira mu buryo bwa molekile), bitewe n'ingaruka zikomeye zo gukwirakwira kwa molekile zo mu kirere, urumuri rw'ubururu rurakwirakwira kugira ngo rwuzure ikirere, kandi ikirere gisa n'ubururu. Iki kintu kizwi nka Rayleigh scattering.

Mu bihe byo kutabona neza, uduce tw'amazi twiyongera ingano kugeza aho tutakibasha kungana n'uburebure bw'urumuri rw'ubururu. Kuri iyi ngingo, ingano yatwo igereranywa n'uburebure bw'urumuri rw'umuhondo-orange-umutuku. Uduce tw'amazi dukunda gukwirakwira no guhagarika urumuri muri iyo migozi, ariko tugaca mu rumuri rw'ubururu. Niyo mpamvu urumuri rw'izuba rimwe na rimwe rushobora kugaragara nk'urw'ubururu cyangwa icyatsi kibisi bitewe n'igihu.

Kuva ku bunini bw'utunyangingo tw'amazi kugeza ku burebure bw'uburebure, amatara ya LED ni yo mahitamo meza ku miterere y'ahantu hatagaragara neza. Ubushyuhe bw'amabara n'imiterere y'amatara bitanga imiterere myiza y'umuhanda mu gihe cy'imvura n'igihu. Mu kunoza imiterere y'amatara ya LED, amatara ya LED atuma imihanda ikomeza kuba myiza mu gihe cy'imvura n'ikirere cy'ibihu.

Niba ushishikajwe n'amatara yo mu muhanda ya LED, ikaze kuvugana n'uruganda rukora amatara yo mu muhanda rwa LED rwa TIANXIANG kugira ngosoma byinshi.
