LED ni iki?
LED bisobanura "Diode Yumucyo." Nigikoresho cya semiconductor gisohora urumuri iyo amashanyarazi ayanyuzemo. LED ikoreshwa muburyo butandukanye bwa porogaramu, zirimo itara, kwerekana, ibipimo, nibindi byinshi. Bazwiho imbaraga zingirakamaro, kuramba, no kuramba ugereranije no kumurika gakondo cyangwa florescent. LED iza mu mabara atandukanye kandi irashobora gukoreshwa muburyo butandukanye bwibicuruzwa, kuva kumatara yoroheje yerekana ibimenyetso kugeza kuri elegitoroniki ya elegitoronike yerekana ndetse no kumurika.
Ihame ryo kumurika LED
Iyo electron hamwe nu mwobo mu ihuriro rya PN rya diode risohora urumuri rwa recombine, electron ziva mu rwego rwo hejuru zikagera ku rwego rwo hasi, kandi electron zikarekura ingufu zirenze urugero muburyo bwa fotone yasohotse (imiraba ya electronique). amashanyarazi. Ibara ryurumuri rufitanye isano nibintu bigize ishingiro. Ibintu nyamukuru bigize nka gallium arsenide diode itanga urumuri rutukura, diode ya gallium fosifide itanga urumuri rwatsi, diode ya silicon karbide itanga urumuri rwumuhondo, na diode ya gallium itanga urumuri rwubururu.
Kugereranya isoko yumucyo
LED. , umucyo mwinshi, ukomeye kandi uramba, Biroroshye gucogora, amabara atandukanye, kwibanda hamwe no kumurika, nta gutinda gutangira.
Itara ryiyongera: imikorere ya electro-optique yo guhindura imikorere (hafi 10%), ubuzima buke (amasaha agera ku 1000), ubushyuhe bwinshi, ubushyuhe bumwe nubushyuhe buke.
Amatara ya Fluorescent: imikorere ya electro-optique yo guhindura imikorere (hafi 30%), yangiza ibidukikije (irimo ibintu byangiza nka mercure, hafi 3.5-5mg / unit), umucyo udahinduka (voltage nto ntishobora gucana), imirasire ya ultraviolet, guhindagurika ibintu, gutangira buhoro Buhoro, igiciro cyibikoresho bidasanzwe byisi byiyongera, guhinduranya inshuro nyinshi bigira ingaruka kumibereho, kandi ingano nini. Amatara yo gusohora gazi yumuvuduko mwinshi: ukoresha imbaraga nyinshi, ni umutekano muke gukoresha, kugira igihe gito, kandi ufite ibibazo byo gukwirakwiza ubushyuhe. Bakoreshwa cyane kumuri hanze.
Ibyiza bya LED
LED ni chip ntoya cyane ikubiye muri epoxy resin, bityo rero ni nto kandi yoroshye. Muri rusange, voltage ikora ya LED ni 2-3.6V, umuyoboro wakazi ni 0.02-0.03A, kandi gukoresha ingufu muri rusange ntabwo birenze
0.1W. Mugihe gihamye kandi gikwiye hamwe nuburyo bukoreshwa, ubuzima bwa serivisi bwa LED burashobora kumara amasaha 100.000.
LED ikoresha tekinoroji ya luminescence ikonje, itanga ubushyuhe buke cyane kuruta urumuri rusanzwe rufite imbaraga zimwe. LED ikozwe mubikoresho bidafite uburozi, bitandukanye n'amatara ya fluorescent arimo mercure, ishobora gutera umwanda. Muri icyo gihe, LED irashobora kandi gukoreshwa kandi ikongera gukoreshwa.
Ikoreshwa rya LED
Nka tekinoroji ya LED ikomeje gukura no gutera imbere byihuse, byinshi kandi byinshi bya LED bigaragara mubuzima bwacu bwa buri munsi. LED ikoreshwa cyane muri LED yerekana, amatara yumuhanda, amatara yimodoka, amasoko yamurika, imitako yamurika, amatara ya LCD ya ecran, nibindi.
Kubaka LED
LED ni chip isohora urumuri, bracket hamwe ninsinga zikubiye muri epoxy resin. Nibyoroshye, bidafite uburozi kandi bifite imbaraga zo kurwanya ihungabana. LED ifite inzira imwe yo gutwarwa iranga, kandi iyo voltage yinyuma iba ndende cyane, bizatera gusenyuka kwa LED. Imiterere nyamukuru yibigize irerekanwa mumashusho:
