I-Photocell
Idivayisi ethola ukukhanya.Isetshenziselwa amamitha okukhanya kwesithombe, izibani zomgwaqo ezizenzakalelayo lapho kuhwalala nezinye izinhlelo zokusebenza ezizwela ukukhanya, i-photocell ishintsha ukumelana kwayo phakathi kwamatheminali ayo amabili ngokusekelwe enanini lama-photon (ukukhanya) eliwamukelayo.Futhi ebizwa ngokuthi “i-photodetector,” “photoresistor” kanye “ne-light dependent resistor” (LDR).
I-photocell's semiconductor material ngokuvamile i-cadmium sulfide (CdS), kodwa ezinye izakhi nazo ziyasetshenziswa.Ama-photocell nama-photodiode asetshenziselwa izinhlelo ezifanayo;nokho, i-photocell idlula i-bi-directionally yamanje, kanti i-photodiode i-unidirectional.
I-Photodiode
Inzwa yokukhanya (i-photodetector) evumela ukugeleza kwamanje ohlangothini olulodwa ukusuka kolunye uhlangothi kuya kolunye lapho idonsa ama-photon (ukukhanya).Ukukhanya okwengeziwe, okwamanje kakhulu.Isetshenziselwa ukuthola ukukhanya kuzinzwa zekhamera, imicu yokubona nezinye izinhlelo zokusebenza ezizwela ukukhanya, i-photodiode iphambene ne-light emit diode (bona i-LED).Ama-Photodiode athola ukukhanya futhi avumele ukugeleza kukagesi;Ama-LED athola ugesi futhi akhipha ukukhanya.
Amaseli eSolar Ama-Photodiode
Amaseli elanga angama-photodiode aphathwa ngamakhemikhali (afakwe) ngendlela ehlukile kune-photodiode esetshenziswa njengeswishi noma i-relay.Lapho amaseli elanga eshaywa ukukhanya, impahla yawo ye-silicon ijabulela isimo lapho kukhiqizwa khona amandla kagesi amancane.Kudingeka izinhlu eziningi zama-solar cell photodiode ukunika amandla indlu.
I-Phototransistor
I-transistor esebenzisa ukukhanya kunogesi ukuze ibangele ukugeleza kukagesi ukusuka kolunye uhlangothi ukuya kolunye.Isetshenziswa ezinhlobonhlobo zezinzwa ezithola ubukhona bokukhanya.Ama-Phototransistors ahlanganisa i-photodiode ne-transistor ndawonye ukuze akhiqize okukhiphayo okuningi kune-photodiode iyodwa.
Ugesi wezithombe
Ukuguqula ama-photons abe ama-electron.Lapho ukukhanya kukhanyiswa ensimbi, ama-electron akhululwa kuma-athomu ayo.Ukuphakama kwefrikhwensi yokukhanya, amandla e-electron akhululwa.Izinzwa ze-Photonic zazo zonke izinhlobo zisebenza kulo mgomo, isibonelo, i-photocell, ne-photovoltaic cell iyisisetshenziswa sikagesi.Zizwa ukukhanya futhi zibangele ukugeleza kwamandla kagesi.
ukwakhiwa
I-photocell iqukethe ithubhu lengilazi elikhishiwe eliqukethe ama-electrode emitter amabili kanye nomqoqi.i-emitter yakheke ngesimo se-semi-hollow cylinder.njalo kugcinwa kumandla angemuhle.umqoqi usesimweni sensimbi yensimbi futhi egxilwe ku-axis ye-semi-cylindrical emitter.umqoqi uhlale egcinwe esesimweni esihle.ithubhu yengilazi ifakwe kusisekelo esingeyona insimbi futhi izikhonkwane zinikezwe ngezansi ukuze kuxhunywe ngaphandle.
sebenza
i-emitter ixhunywe kutheminali enegethivu futhi umqoqi uxhunywe kutheminali ephozithivu yebhethri.imisebe yefrikhwensi engaphezu kwemvamisa ye-threshold yempahla ye-emitter yenziwa isigameko ku-emitter.ukukhishwa kwesithombe kwenzeka.ama-photo-electrons akhangwa umqoqi okusho kahle ukuthi i-emitter igeleza manje kusekethe.uma ubukhulu bemisebe yesigameko bukhuphuka ukwanda kwamanje kwe-photoelectric.
Ezinye izimo zethu zohlelo lokusebenza lwe-photocontrol
Umsebenzi weswishi ye-photocell ukuthola amazinga okukhanya okuvela elangeni, bese uvula noma uvale izinto ezixhunywe kuzo izintambo.Lobu buchwepheshe bungasetshenziswa ngezindlela eziningi, kodwa esinye sezibonelo ezivame kakhulu kungaba izibani zomgwaqo.Ngenxa yezinzwa ze-photocell namaswishi, zonke zingavulwa futhi zicishwe ngokuzenzakalelayo futhi ngokuzimela ngokusekelwe ekushoneni kwelanga nokuphuma kwelanga.Lokhu kungaba yindlela enhle yokonga amandla, ube nezibani ezizenzakalelayo zokuphepha noma nje ukuthi izibani zakho zasengadini zikhanyise izindlela zakho ebusuku ngaphandle kokuthi uzikhanyise.Kunezindlela eziningi ezihlukene zokusebenzisa ama-photocell izibani zangaphandle, ngezinhloso zokuhlala, ezohwebo noma zezimboni.Udinga kuphela ukuthi ube neswishi ye-photocell eyodwa exhunywe kwisekethe ukuze ukwazi ukulawula zonke izinto ezilungiswayo, ngakho-ke asikho isidingo sokuthenga iswishi eyodwa isibani ngasinye.
Kunezinhlobo eziningi ezahlukene zokushintshwa kwe-photocell nezilawuli, zonke zifaneleka kangcono izimo ezihlukene kanye nezinzuzo ezihlukahlukene.Ukushintsha okulula ukukukhweza kuzoba ama-photocell akhweza isiqu.Izilawuli ze-swivel nazo zilula kakhulu ukuzifaka kodwa zinikeza ukuguquguquka okwengeziwe.Izilawuli zezithombe ze-Twist-Lock zinzima kakhulu ukuzifaka, nokho ziqine kakhulu futhi zakhelwe ukumelana nokudlidliza kanye nemithelela emincane ngaphandle kokuphuka noma ukubangela ukunqanyulwa kumjikelezo.Ama-photocells enkinobho afaneleka kahle ezibanini zangaphandle, adizayinelwe ukugxunyekwa kalula ngezigxobo.
