Muaj pes tsawg volts lub teeb emitting diode yuav tsum tau teeb?
Dab tsi yog qhov ua haujlwm voltage ntawm lub teeb emitting diode?
Paub txog qhov voltage poob ntau ntawm lub teeb-emitting diode, koj kuj paub tias pes tsawg volts lub teeb-emitting diode tuaj yeem emit lub teeb.
Lub teeb-emitting diode tuaj yeem ua haujlwm ib txwm, thiab qhov teeb meem ntawm lub teeb emission yuav ploj mus.
Cia peb saib qhov kev khiav hauj lwm voltage ntawm lub teeb-emitting diode.
Lub rau pem hauv ntej voltage ntawm lub teeb-emitting diodes feem ntau yog nruab nrab ntawm 1.5 volts thiab 3.3 volts.
Thaum sab nraud kub nce, tus nqi voltage yuav txo.
Qhov no yog yam ntxwv ntawm LED voltage.
Nyob rau tib lub sij hawm, nws kuj yog qhov hluav taws xob parameter yam ntxwv ntawm lub teeb-emitting diodes.
Tsawg tam sim no, tsis tshua muaj hluav taws xob, ib puag ncig tus phooj ywg LED yam ntxwv, LED voltage yog destined tsis siab.
Thiab qhov tsawg voltage nyob rau hauv 36 volts yog ib tug muaj kev ruaj ntseg voltage.
Xws li ib qho hluav taws xob tsis muaj kev phom sij lossis kev puas tsuaj rau tib neeg lub cev.
Nws txhais tau tias me me tam sim no thiab tsis tshua muaj hluav taws xob tuaj yeem teeb.
Xws li lub teeb hlaws hluav taws xob yog lub roj teeb thib 7, thiab lub roj teeb thib 5 tuaj yeem teeb.
LEDs xav tau ob peb volts los teeb.
2-3 volts.
Feem ntau, lub teeb pom kev zoo ntawm lub teeb liab, lub teeb daj, lub teeb daj-ntsuab, thiab lub teeb txiv kab ntxwv yog qhov tsawg, txog 2 volts.
Lub teeb pom kev zoo ntawm lub teeb dawb, lub teeb emerald, lub teeb xiav, thiab lub teeb liab liab yog qhov siab, txog 3 volts.
Raws li rau high-voltage lub teeb sawb, qhov dav LED voltage yog 6 volts, 9 volts, 18 volts, thiab 36 volts mus teeb.
Nyob rau hauv pab pawg neeg, cov neeg feem ntau nug txog qhov voltage poob ntawm lub teeb-emitting diodes.
Nws hais tias, xibfwb Lamp Bead, qhov dav dav voltage poob ntawm LEDs yog dab tsi?
Kuv hais tias, nws nyob ntawm seb cov xim twg lub siab poob yog.
Feem ntau, qhov voltage poob ntawm cov xim sib txawv ntawm lub teeb-emitting diodes txawv.
Piv txwv li, qhov voltage poob ntawm lub teeb liab feem ntau yog 1.6-2.4 volts.
Qhov ntsuas hluav taws xob poob qis yog cuam tshuam nrog lub teeb xim, thiab qhov ntsuas hluav taws xob poob qis yog qhov qis dua thiab siab dua voltage ntau ntawm cov xim.
Tsawg voltage, qhov voltage uas lub teeb-emitting diode tuaj yeem teeb.
High voltage, qhov voltage siab tshaj qhov ntsuas ua hauj lwm voltage ntawm lub teeb-emitting diode.
Feem ntau, thaum peb teeb lossis ua haujlwm, peb ua haujlwm hauv qhov hluav taws xob no.
Qhov no kuj yog vim li cas rau lub neej ua haujlwm ntev ntawm lub teeb-emitting diodes.
Yog tias tus nqi ntau tshaj qhov no, lub teeb-emitting diode yuav tsis teeb, lossis lub teeb-emitting diode yuav raug hlawv yooj yim.
