Nigute LED itanga urumuri?

Electroluminescence ninzira LEDs (Light Emitting Diode) itanga urumuri. Uku nuburyo bukora:

1-Ibikoresho bya Semiconductor: Ibikoresho bya semiconductor, mubisanzwe bivanze nibintu nka fosifori, arsenic, cyangwa gallium, bikoreshwa mugukora LED. Agace kombi n-ubwoko (bubi), gafite electron zirenze, hamwe nakarere ka p-positif (positif), gafite ibura rya electron (umwobo), bikozwe mugihe igice cya semiconductor cyuzuyemo umwanda.

2-Kwiyubaka kwa Electron-Hole: Electron ziva mukarere ka n-zihatirwa kwerekeza mukarere ka p mugihe voltage ishyizwe hejuru ya LED. Izi electron zisubirana hamwe nu mwobo mukarere ka p.

3-Imyuka ya Photon: Ingufu zisohoka nkumucyo (fotone) muriki gikorwa cyo kwiyubaka. Ingufu zingirakamaro yibikoresho bya semiconductor ikoreshwa bigena hue yumucyo urekurwa. Umucyo uza mumabara atandukanye bitewe nibikoresho.

4-Gukora neza: Kubera ko ingufu nyinshi muri LED zahinduwe mumucyo aho kuba ubushyuhe-ikibazo gikunze kugaragara kumatara asanzwe-LED ikora neza kuburyo budasanzwe.

5-Encapsulation: Mugukingira LED mumurongo usobanutse cyangwa lens, urumuri rutanga ruba rwiza cyane. Ibi birashobora kandi gufasha gukwirakwiza urumuri no kugaragara neza.

Ugereranije nuburyo busanzwe bwo kumurika, ubu buryo butuma LED itanga urumuri rwinshi, rwibanze mugihe ukoresha ingufu nke cyane.

Nubwo kuramba kwinshi no gukora neza, amatara ya LED arashobora kugira ibibazo bisanzwe, nka:
1) Itandukaniro ryubushyuhe bwamabara: Itara ridahuye mukarere rishobora guturuka kumihindagurikire yubushyuhe bwamabara hagati yamatara ya LED.

2) Guhindagurika: Iyo ikoreshejwe hamwe na dimmer idahuye cyangwa mugihe hari ibibazo bijyanye no gutanga amashanyarazi, amatara amwe ya LED arashobora gucana.

3) Ubushyuhe bukabije: LED itanga ubushyuhe buke ugereranije n’amatara asanzwe, ariko ubushyuhe budahagije bushobora gutera ubushyuhe bwinshi, bushobora kugabanya itara.

4) Ibibazo byabashoferi: Kugirango ugenzure ingufu, amatara ya LED akenera abashoferi. Itara rishobora guhindagurika, gucogora, cyangwa guhagarika gukora rwose niba umushoferi akora nabi cyangwa afite ubuziranenge.

5) Dimming Compatibility: Ibibazo byimikorere birashobora kuvuka kuko amatara amwe ya LED ntaho ahuriye na dimmer ya switch.

6) Inguni ntarengwa: Itara ritaringaniye rishobora guturuka kumatara ya LED hamwe nurumuri ruto, bishobora kuba bidakwiriye kubisabwa byinshi.

7) Igiciro cyambere: Nubwo amatara ya LED abika amafaranga mugihe, arashobora kugura amafaranga menshi kugura mbere kuruta amatara asanzwe.

8) Ibidukikije: Niba bidatunganijwe neza, urwego rwibintu byangiza nka gurş cyangwa arsenic biboneka mumatara amwe ya LED bishobora guhungabanya ibidukikije.

9) Guhinduka mubyiza: Hano ku isoko hari ibicuruzwa byinshi bitandukanye LED, kandi ntabwo byose bikozwe mubipimo bimwe, bitera guhinduka kuramba no gukora.

10) Kudahuza nibikoresho bimwe: Amatara amwe ya LED, cyane cyane ayakorewe kumatara asanzwe yaka, ntashobora gukora neza muburyo bwihariye.

Guhitamo ibintu byiza-byiza, kureba neza ko bikorana na sisitemu zigezweho, kandi ukurikije amabwiriza yo kwishyiriraho birakenewe kenshi kugirango bikemuke.

Hano hari imirongo myinshi yoroheje yo guhitamo kumasoko ubungubu, nkaIkarita ya COBCSP umurongo, bitandukanye naSMD, twandikire niba ukeneye ingero zo kwipimisha.
