Photocell
Sesebedisoa se lemohang kganya.E sebelisoa bakeng sa limithara tse khanyang tsa lifoto, mabone a seterateng ka ho toba ka shoalane le lisebelisoa tse ling tse sa utloeng bohloko, photocell e fapana ho hanyetsa pakeng tsa li-terminals tsa eona tse peli ho latela palo ea photon (leseli) eo e e fumanang.E boetse e bitsoa "photodetector," "photoresistor" le "light dependent resistor" (LDR).
Lisebelisoa tsa photocell's semiconductor hangata ke cadmium sulfide (CdS), empa likarolo tse ling le tsona lia sebelisoa.Li-photocell le li-photodiode li sebelisetsoa lits'ebetso tse tšoanang;leha ho le joalo, photocell e feta hona joale ka mahlakoreng a mabeli, athe photodiode ha e le hantle.
Photodiode
Sensor e khanyang (photodetector) e lumellang hona joale ho phalla ka lehlakoreng le leng ho tloha ka lehlakoreng le leng ho ea ho le leng ha e nka photons (leseli).Ha leseli le ntse le eketseha, le ntse le eketseha.E sebelisetsoa ho bona leseli ho li-sensor tsa khamera, li-fiber tsa optical le lisebelisoa tse ling tse sa utloeng khanya, photodiode e fapane le khanya e ntšang diode (sheba LED).Li-photodiode li lemoha leseli 'me li lumella motlakase ho phalla;Li-LED li fumana motlakase 'me li ntša leseli.
Lisele tsa Solar ke li-Photodiode
Lisele tsa letsatsi ke li-photodiode tse tšoaroang ka lik'hemik'hale (doped) ka tsela e fapaneng le ea photodiode e sebelisoang e le switch kapa relay.Ha lisele tsa letsatsi li otloa ke khanya, lisebelisoa tsa bona tsa silicon li thabela boemo boo ho hlahisoang motlakase o monyenyane oa motlakase.Ho hlokahala mefuta e mengata ea li-solar cell photodiode ho matlafatsa ntlo.
Phototransistor
Transistor e sebelisang khanya ho fapana le motlakase ho etsa hore maqhubu a motlakase a phalle ho tloha lehlakoreng le leng ho ea ho le leng.E sebelisoa mefuteng e fapaneng ea li-sensor tse lemohang boteng ba leseli.Li-Phototransistors li kopanya photodiode le transistor hammoho ho hlahisa lihlahisoa tse ngata ho feta photodiode ka boeona.
Motlakase oa lifoto
Ho fetolela li-photon ho li-electrone.Ha leseli le khantšitsoe tšepeng, lielektrone li lokolloa liathomong tsa eona.Ha khanya ea khanya e phahame, matla a elektronike a mangata a lokolloa.Li-sensor tsa photonic tsa mefuta eohle li sebetsa ho latela molao-motheo ona, mohlala, photocell, le photovoltaic cell ke sesebelisoa sa elektronike.Li utloa khanya 'me li etsa hore maqhubu a motlakase a phalle.

Boemo ba rona bo bong ba ts'ebeliso ea photocontrol
Mosebetsi oa sesebelisoa sa photocell ke ho bona maemo a khanya a tsoang letsatsing, ebe o bulela kapa o tima lisebelisoa tseo li kentsoeng ho tsona.Theknoloji ena e ka sebelisoa ka litsela tse ngata, empa e 'ngoe ea mehlala e tloaelehileng e ka ba mabone a seterateng.Ka lebaka la li-sensor tsa photocell le li-switches, kaofela li ka buloa le ho tima ka mokhoa o ikemetseng ho ipapisitse le ho likela ha letsatsi le ho chaba ha letsatsi.Ena e ka ba mokhoa o motle oa ho boloka matla, ho ba le mabone a ts'ireletso a iketsang kapa ho etsa hore mabone a jareteng ea hau a bonese litsela tsa hau bosiu ntle le ho a bulela.Ho na le mekhoa e mengata e fapaneng ea ho sebelisa li-photocells bakeng sa mabone a kantle, molemong oa bolulo, khoebo kapa indasteri.U hloka feela ho ba le sesebelisoa se le seng sa photocell se kenngoeng ka har'a potoloho ho khona ho laola lisebelisoa tsohle, kahoo ha ho hlokahale hore u reke sesebelisoa se le seng ka lebone.
