Kuki abantu benshi kandi benshi bakunda gukoresha amatara ya LED aho gukoresha amatara yaka?
Hano hari kugereranya, birashoboka ko byadufasha kubona igisubizo.
Itandukaniro ryambere hagati yamatara yaka n'amatara ya LED nihame ryohereza urumuri.Itara ryaka kandi ryitwa itara ry'amashanyarazi.Ihame ryakazi ryayo nuko ubushyuhe butangwa mugihe ikigezweho kinyuze muri filament.Firament ya spiral ikomeza gukusanya ubushyuhe, bigatuma ubushyuhe bwa filament burenga dogere selisiyusi 2000.Iyo filament iri muburyo butagaragara, irasa nicyuma gitukura.Irashobora gusohora urumuri nkuko rumurika.
Iyo ubushyuhe buri hejuru ya filament, niko urumuri rwinshi, bityo rwitwa itara ryaka.Iyo amatara yaka asohora urumuri, ingufu nyinshi zamashanyarazi zizahinduka ingufu zubushyuhe, kandi igice gito gusa gishobora guhinduka ingufu zingirakamaro.
Amatara ya LED nayo yitwa diode itanga urumuri, ni ibikoresho bikomeye bya semiconductor bishobora guhindura amashanyarazi mumucyo.Umutima wa LED ni chip ya semiconductor, impera imwe ya chip ifatanye na brake, impera imwe ni pole mbi, naho iyindi ihujwe na pole nziza yo gutanga amashanyarazi, kuburyo chip yose iba ifunze epoxy resin.
Wafer ya semiconductor igizwe n'ibice bitatu, igice kimwe ni P-semiconductor yo mu bwoko bwa P, aho imyobo yiganje, urundi ruhande ni N-semiconductor ya N, hano ahanini ni electron, kandi hagati ni kwantum iriba rifite 1 kugeza 5 inzinguzingu.Mugihe ikigezweho gikora kuri chip ukoresheje insinga, electron nu mwobo bizasunikwa mumariba ya kwant.Mu mariba ya kwant, electron nu mwobo birongera hanyuma bigasohora ingufu muburyo bwa fotone.Iri ni ihame ryo gusohora urumuri rwa LED.
Itandukaniro rya kabiri riri mumirasire yubushyuhe ikorwa byombi.Ubushyuhe bw'itara ryaka burashobora kumvikana mugihe gito.Nimbaraga nini, nubushyuhe bwinshi.Igice cyo guhindura ingufu z'amashanyarazi ni urumuri naho igice cy'ubushyuhe.Abantu barashobora kumva neza ubushyuhe butangwa n itara ryaka cyane iyo begereye cyane..
Ingufu z'amashanyarazi LED zihindurwamo ingufu zoroheje, kandi imirasire yubushyuhe ikorwa ni mike cyane.Byinshi mubushobozi bihinduka muburyo butaziguye imbaraga zumucyo.Byongeye kandi, imbaraga z'amatara rusange ni make.Ufatanije nuburyo bwo gukwirakwiza ubushyuhe, imirasire yubushyuhe ya LED itanga urumuri rukonje iruta iy'amatara yaka.
Itandukaniro rya gatatu nuko amatara yatanzwe na yombi atandukanye.Umucyo utangwa n'itara ryaka ni urumuri rwuzuye-amabara, ariko igipimo cyibigize amatara atandukanye yamabara agenwa nibintu bya luminescent nubushyuhe.Ikigereranyo kitaringaniye gitera ibara ryurumuri, bityo ibara ryikintu munsi y itara ryaka ntiriba rihagije bihagije.
LED ni urumuri rwatsi.Itara rya LED ritwarwa na DC, nta stroboskopi, nta bikoresho bya infragre na ultraviolet, nta ihumana ry’imirasire, ugereranije amabara menshi kandi yerekana neza.
Ntabwo aribyo gusa, urumuri rwa LED rufite imikorere myiza yo gucana, ntamakosa agaragara abaho mugihe ubushyuhe bwamabara buhindutse, kandi urumuri rukonje rufite ubushyuhe buke kandi rushobora gukorwaho neza.Irashobora gutanga urumuri rwiza kandi rwiza Nisoko yumucyo muzima urinda amaso kandi yangiza ibidukikije kugirango abantu babone ubuzima bwumubiri.
