Ihame rya lumanous ryo kuyobora

ByoseUmucyo wo gukosora, urumuri rwimukanwanaUmuyobozi MultifunccalKoresha ubwoko bwa LESB. Kugira ngo wumve ihame rya Diode LED, ubanza gusobanukirwa ubumenyi bwibanze bwa semicokoko. Ibikoresho bitwara ibikoresho bya semiconductor biri hagati yabayobora na bagenzi bacu. Ibiranga byihariye ni: Iyo Semiconductor yatewe itara nubushyuhe bwo hanze nubushyuhe, ubushobozi bwabwo buzahinduka kuburyo bugaragara; Ongeraho umubare muto wumwanda utunganijwe neza wongera cyane ubushobozi bwayo bwo kuyobora amashanyarazi. Silicon (Si) na Gerecium (Ge) nizo zikoreshwa mu buryo bukoreshwa mu buryo bwa elegitoroniki igezweho, kandi electron yabo yo hanze ni ine. Iyo atome cyangwa atome yubudage ikora akantu ka kristu, ituranye gasabana, kugirango electron yo hanze isangirwe na atome ebyiri, ikora imiterere ya costaley muri Crystal, nuburyo bubi hamwe nubushobozi buke bwo kubungabunga. Ku bushyuhe bwicyumba (300k), ubushyuhe buzatuma habaho electron yo hanze kubona imbaraga zihagije zo gutandukana nubucuti bwa covoricst no kuba electron yubusa, iyi nzira yitwa electination. Nyuma ya electron idashobora kuba electron yubusa, umwanya usigaye mumwobo wa covoricst. Ikiruhuko cyitwa umwobo. Kugaragara kwumwobo nikintu cyingenzi gitandukanya semiconductor kuva kumurongo.

Iyo umubare muto wa pentavuriho nka fosifore wongeyeho kuri seminsic ecminsic, izaba ifite electron yongeyeho nyuma yo gukora ubumwe bwa covokileya na atome ya semiconductor. Iyi electron yinyongera ikeneye gusa imbaraga nto cyane kugirango ukureho ingwate hanyuma uhinduke electron yubusa. Ubu bwoko bwimyambarire yitwa Electronic Semiconductor (n-ubwoko semiconductor). Ariko rero, wongeyeho umubare muto wanduye (nka Boron, nibindi) kuri Seconductor yimbere, kuko ifite ubumwe bwa electon yo hanze, nyuma yo gukora ubumwe bwa seminichuct atome yinyuma, bizatera umwanya muri kristu. Ubu bwoko bwa kashe emiconductor bwitwa umwobo (p-ubwoko bwa semiconductor). Iyo n-ubwoko nubu bwoko bwa semicondo ya hamwe, hari itandukaniro ryo kwibanda kuri electron yubusa ninzoka mumaso yabo. Electron na myibo byombi biratandukanye kugirango habeho kwibanda, gusiga inyuma yiregwa ariko utibuka imyenda yimuka isenya amashanyarazi yumwimerere yuburyo bwa n-ubwoko nubwoko bwa p-ubwoko. Ibi bitibuka byinkuta bikunze kwitwa amafaranga yumwanya, kandi bibanze hafi yimbere ya N na P Uturere duto tworoheje cyane mumwanya wumwanya, uzwi nka PN.

Iyo gufata kuri bo muri bia ikoreshwa kumpande zombi za PN (voltage nziza kuruhande rumwe rwubwoko bwa p-ubwoko), umwobo hamwe na electrons yubusa bimuka, bigakora amashanyarazi imbere. Impunzi zihenze noneho recombine hamwe na electron yubusa, rimwe na rimwe kurekura imbaraga zirenze muburyo bwa fotone, aribyo urumuri tubona rwasohotse na LED. Imyitozo nkiyi ni ntoya, kandi kubera ko buri kintu gifite icyuho gitandukanye, uburebure bwamafoto yasohotse buratandukanye nibikoresho byibanze byakoreshejwe.
