Ni gute LED ikora urumuri?

Electroluminescence ni inzira LED (Light Emitting Diodes) zikoresha mu gutanga urumuri. Uku ni ko bikora:

1-Ibikoresho bya Semiconductor: Ibikoresho bya semiconductor, ubusanzwe biba bivanze n'ibintu nka fosforasi, arsenic, cyangwa gallium, bikoreshwa mu gukora LED. Agace ka n-type (negative), gafite electrons nyinshi, n'agace ka p-type (positive), gafite ibura rya electrons (imyobo), bitangwa iyo semiconductor ishyizwemo imyanda.

Guhuza Uduce twa Electron-Hole 2: Electron zo mu gace ka n-type zishyirwa mu gace ka p-type iyo voltage ishyizwe kuri LED. Izi electron zihurira hamwe n'utwobo mu gace ka p-type.

Ibyuka bya Fotoni 3: Ingufu zisohoka nk'urumuri (fotoni) muri iki gikorwa cyo gusubiranamo. Ingufu zishyirwa mu bikoresho bya semiconductor zikoreshwa zigena ibara ry'urumuri rurekurwa. Umucyo uza mu mabara atandukanye bitewe n'ibikoresho.

4-Ingufu: Kubera ko ingufu nyinshi muri za LED zihinduka urumuri aho kuba ubushyuhe—ikibazo gikunze kugaragara ku matara asanzwe akoresha incandescent—LED zikora neza cyane.

5-Gushyira urumuri mu ruhu: Gushyira urumuri rwa LED mu ruhu cyangwa mu ruhu rw'ijisho rusobanutse neza, bituma urumuri rutangwa rurushaho kunozwa. Ibi bishobora kandi gufasha gukwirakwiza urumuri no kurugaragaza neza.

Ugereranyije n'uburyo busanzwe bwo kumurika, ubu buryo butuma LED zitanga urumuri rwinshi kandi rwinshi mu gihe zikoresha ingufu nke cyane.

Nubwo amatara ya LED aramba kandi agatanga umusaruro mwinshi, ashobora kugira ibibazo byinshi bisanzwe, nko:
1) Ihinduka ry'ubushyuhe bw'amabara: Amatara adahuye n'ahari ahantu ashobora guterwa n'impinduka z'ubushyuhe bw'amabara hagati y'amatara ya LED.

2) Gucana: Iyo ikoreshejwe hamwe n'amatara adahuza cyangwa iyo hari ibibazo ku itangwa ry'amashanyarazi, amatara amwe ya LED ashobora gucana.

3) Gushyuha cyane: Amatara ya LED atanga ubushyuhe buke ugereranyije n'amatara asanzwe, ariko kudakoresha ubushyuhe bihagije bishobora gutuma amatara ashyuha cyane, ibyo bikaba byagabanya igihe cyo kubaho cy'amatara.

4) Ibibazo by'Umushoferi: Kugira ngo amatara ya LED agenzurwe neza, akeneye abashoferi. Itara rishobora gukanguka, gucika, cyangwa guhagarika gukora burundu niba umushoferi akoze nabi cyangwa afite ubuziranenge buke.

5) Guhuza imiterere y'urumuri: Ibibazo by'imikorere bishobora kuvuka kubera ko amatara amwe ya LED adahuye n'amatara akoresha urumuri rw'urumuri.

6) Inguni y'umurabyo muke: Amatara adahuje ashobora guterwa n'amatara ya LED afite inguni y'umurabyo muke, ibyo bikaba bitagomba gukoreshwa mu bikorwa byinshi.

7) Igiciro cya mbere: Nubwo amatara ya LED azigama amafaranga uko igihe kigenda gihita, ashobora kugurwa menshi mu ntangiriro kurusha amatara asanzwe.

8) Ibibazo ku Bidukikije: Iyo bitajugunywe neza, urugero rw'ibintu biteje akaga nka lisansi cyangwa arsenic biboneka mu matara amwe ya LED bishobora gushyira mu kaga ibidukikije.

9) Ihindagurika ry'Ubwiza: Hari ibicuruzwa byinshi bitandukanye bya LED ku isoko, kandi si byose bikorwa ku rugero rumwe, ibyo bigatuma habaho ihindagurika mu kuramba no gukora.

10) Kudahuza n'ibikoresho bimwe na bimwe: Amatara amwe ya LED, cyane cyane ayakorewe amatara asanzwe akoresha incandescent, ntiyashoboraga gukora neza mu bikoresho bimwe na bimwe.

Guhitamo ibintu byiza, kugenzura ko bikorana na sisitemu zigezweho, no gukurikiza amabwiriza yo gushyiraho, akenshi ni ngombwa kugira ngo ibyo bibazo bikemuke.

Hari uduce twinshi tw'urumuri two guhitamo ku isoko ubu, nkoAgace ka COBUmurongo wa CSP, utandukanye n'uwaAgace ka SMDTwandikire niba ukeneye ingero zo gupimisha.
