74FCT3807DQGI8 ic cihp ihuriweho numuzunguruko wa elegitoroniki ishyushye kugurisha shyashya kandi umwimerere ahantu hamwe gusa kugura serivise

1．LED ni ubwoko bushya bwibikoresho bikora neza kandi bitangiza ibidukikije igice cya kabiri cyumucyo.Ugereranije nandi masoko yumucyo, LED ifite ibyiza byinshi mumatara yimodoka kandi ifite ibyifuzo byinshi.Uburyo butandukanye bwo guhuza LED murukurikirane kandi bigereranywa no gukora imirongo ya LED ikoreshwa kugirango ihuze ibyifuzo byumuriro wimodoka.

Hamwe niterambere ryikoranabuhanga hamwe niterambere ryihuse ryubukungu bwimibereho, ibicuruzwa bya LED byakoreshejwe cyane mubuzima bwabantu.Ikinyejana cya 21, umusaruro wa LED nubunini bwisoko bigeze kurwego rutigeze rubaho, isoko yingenzi yo gukoresha LED ni ahantu hatandukanye herekanwa, ibirango bitandukanye bya terefone zigendanwa, nibindi.Mubyongeyeho, LED igira uruhare runini mumihanda, kumurika ibyubatswe, gushushanya imbere, nibindi bice byinshi.Hamwe niterambere ryihuse ryinganda zitwara ibinyabiziga, imiyoboro ya LED ikoreshwa cyane mubikoresho bya elegitoroniki bigezweho, kandi amasoko yabanjirije amamodoka nkamatara agenda asimburwa buhoro buhoro.Muri icyo gihe, LED ifite imikorere yumucyo mwinshi, igihe gito cyo gusubiza (igisubizo cyihuse), imiterere yoroheje (ingano nto), igihe kirekire cya serivisi, nibindi biranga, izakoreshwa mumatara yimodoka kandi ifite kandi ivangura rikomeye ryamabara kandi irwanya -ibiranga.Nyamara, kubera imbogamizi zimpamvu zitandukanye, LED iracyafite inenge zimwe, igomba gukomeza kunoza ikoranabuhanga rya LED, kugirango irusheho gukenera ibikoresho bya elegitoroniki.

2.LED nigikoresho cya semiconductor igikoresho cyumucyo usohora diode, ikozwe mubice bimwe bya semiconductor.LED nisoko yumucyo hamwe no kurwanya neza kunyeganyega no guhungabana, irinzwe na epoxy resin cap, intangiriro ni nto cyane, kandi intangiriro ni intangiriro ya PN, bityo ikaba ifite ibiranga ihuriro rya PN, ni ukuvuga gutwara imbere. , guhindagura gukata no gusenyuka birenze urugero, nibindi. Muri bimwe bidasanzwe Mubihe bimwe bidasanzwe, birashobora kandi kurangwa nkibisohora urumuri.

3.Imiyoboro ya LED igabanijwemo ubwoko bubiri bwimodoka: guhora mumashanyarazi ya voltage hamwe na disiki ihoraho.Bitewe nuburyo buhoraho bwo gutwara ibinyabiziga LED, muburyo bwa PN ihuza-shingiro, irashobora kuba umubano werekana kwerekana voltage ya LED nimpinduka zubu, bityo ikoreshwa cyane.Uburyo bwo guhora-voltage yo gutwara muri rusange ni ugukoresha ubushobozi bwa anti-capacitance kumanuka cyangwa kumanura hasi kumashanyarazi, gukoresha diode ya voltage igenga cyangwa guhinduranya uburyo bwo gutanga amashanyarazi, kumashanyarazi ya LED, ariko ibiranga urumuri rwa LED bizaba biriho ubu guhora uhinduka munsi yingaruka zijyanye.Igenzura ry'umurongo muburyo buhoraho bwo gutwara ibinyabiziga bifite ubwoko bubiri: bubangikanye hamwe nuruhererekane, intandaro ni power triode cyangwa MOSFET ikorera muri zone y'umurongo nkumwanya uhindura imbaraga kugirango ugenzure umutwaro.umuyagankuba numuyoboro kumpande zombi za LED ntabwo ari isano yumurongo, ntishobora gukoreshwa muburyo butaziguye nisoko ya voltage, kandi igomba kugarukira mukugabanya umuyaga kugirango wirinde umuyaga mwinshi kandi wirinde kwangirika kuri LED.LED luminous flux na current ntabwo aribyo Luminous flux ntago ihwanye nubu, flux yamashanyarazi yiyongera hamwe numuyoboro, bafite impamyabumenyi zitandukanye zingufu zamashanyarazi, kurwanya imbere, hamwe nimbogamizi zishobora kuba zimwe, kuburyo zidashobora gukoreshwa mu buryo butaziguye.Hitamo uburyo bwiza kandi bushyize mu gaciro bugomba gutekereza kuri porogaramu no gushyira mu gaciro kwayo, kubwoko ubwo aribwo bwose, basabwa guhitamo muburyo bwo guhinduranya amashanyarazi, uburyo busanzwe ni PFM, uburyo bwa PWM, hamwe no kugenzura amashusho ya firime, aribyo ni byoroshye kandi byoroshye uburyo bwo kugenzura uburyo bwa PWM, burashobora kugumana inshuro zihamye mubikorwa, ariko kandi bigomba no gutekereza kubitekerezo bizigama ingufu hamwe nibindi byerekezo, kugirango urumuri rwa LED ruhite, kandi bigabanye gukoresha LED.
