Kev tiv thaiv tam sim no ntawm dodes nyob rau hauv lub tsev teeb pom kev zoo

1, Cov yam ntxwv yooj yim ntawm diodes thiab lawv lub luag haujlwm hauv kev tiv thaiv tam sim no
Ib tug diode yog semiconductor ntaus ntawv nrog unidirectional conduction uas tso cai rau tam sim no ntws hauv ib qho kev tiv thaiv tam sim no los ntawm kev ntws hauv lwm qhov kev taw qhia. Tus xeeb ceem no ua rau kev ua haujlwm lom zem
Rectification muaj nuj nqi: Txawm hais tias muaj feem cuam tshuam nrog cov txheej txheem txuas ntxiv kom hloov lub tshuab hluav taws xob (xws li roj teeb) rau hauv cov teeb pom kev zoo rau LED teeb pom kev zoo. Thaum lub sijhawm cov txheej txheem no, diodes tuaj yeem ua kom muaj kev tsis txaus ntseeg ntws los ntawm tam sim no thiab tiv thaiv rov qab tam sim no los ntawm kev puas tsuaj rau kev puas tsuaj rau led kho.
Tam sim no txwv cov nyhuv tam sim no: nyob rau hauv LED teeb pom kev zoo, tshwj xeeb yog schottky donetkes) tuaj yeem txwv qhov kev hla dhau los ntawm lawv cov yam ntxwv Volte. Thaum lub zog muab voltage nce lossis lub nra hloov, cov diode hloov tau nws lub xeev kev ruaj khov ntawm LED kev puas tsuaj los ntawm overcurrent.
Kev Tiv Thaiv Kev Tiv Thaiv Cov Tshuab Ntse
Kev Tiv Thaiv Rov Qab: Txhawm rau tiv thaiv cov khoom siv kev puas tsuaj los ntawm kev thim rov qab polarity ntawm lub zog hluav taws xob, thim kev tiv thaiv dodes feem ntau siv nyob rau hauv lub tsev teeb pom kev ntse. Cov diode no yog nyob rau hauv ib tug txiav - tawm ntawm lub xeev thaum lub zog polarity muaj tseeb, thiab tsis cuam tshuam rau txoj haujlwm ib txwm muaj ntawm Circuit Court; Thaum lub polarity ntawm lub zog hluav taws xob yog thim rov qab, cov teeb meem ua tiav, hla kev rov qab tam sim no thiab tiv thaiv lub teeb LED los ntawm kev puas tsuaj.
2, Daim ntawv thov ntawm kev tiv thaiv tam sim no ntawm dodes nyob rau hauv lub tsev teeb pom kev zoo
Cov kev tiv thaiv tam sim no hauv LED Tsav Circuits: hauv LED teeb pom kev zoo yog lub luag haujlwm rau kev hloov lub zog hluav taws xob ua kom haum rau kev siv nrog LED fixtures. Txhawm rau tiv thaiv overcurrent tshwm sim los ntawm kev muab hluav taws xob hluav taws xob hloov chaw lossis cov neeg tsim qauv sib hloov, feem ntau ntxiv cov kev txwv tam sim no ntxiv rau kev tsav tsheb. Cov dailes no tuaj yeem kho lawv lub xeev uas muaj zog raws li lub zog hluav taws xob thiab kev thauj khoom, yog tswj qhov ruaj khov ntawm LED tam sim no.
Kev tsim qauv ntawm kev tiv thaiv kev tiv thaiv cov tshuab hluav taws xob: cov chaw teeb pom kev zoo feem ntau ntsib kev hem thawj sab nraud xws li Grid voltage hloov pauv thiab xob laim. Txhawm rau tiv thaiv LED teeb los ntawm overvoltage kev puas tsuaj, cov neeg tsim qauv feem ntau ntxiv cov kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kab ke hauv Circuit Court hauv Circuit Court. Cov Uiodes no tuaj yeem teb sai sai thaum lub zog hluav taws xob nce siab txawv txav, bypassing dhau voltage kom tiv thaiv LED teeb tsa fixtures thiab lwm cov khoom tseem ceeb.
Daim ntawv thov kev tiv thaiv rov qab tiv thaiv kev tiv thaiv lub tsev ntse, cov neeg tsim qauv feem ntau ntxiv kev tiv thaiv kev tiv thaiv rov qab los ntawm cov neeg siv kev tsis sib xws ntawm lub hwj chim polarity. Cov Uiodes ua kom pom tseeb tias lub Circuit Court ua haujlwm kom raug thaum lub zog polarity yog hloov kho, hla kev rov qab sai thiab tiv thaiv lub teeb pom kev zoo los ntawm kev puas tsuaj.
Kev siv ntawm Thermal tiv thaiv lub tswv yim: LED teeb ua kom muaj qee qhov nyiaj ntawm kev ua haujlwm. Yog tias cov cua sov dissipation yog cov neeg pluag, nws yuav ua rau txo qis hauv kev ua tau zoo lossis muaj kev puas tsuaj. Txhawm rau kom daws tau cov teeb meem no, cov neeg tsim qauv feem ntau ntxiv cov cua sov ntxiv thiab kev tiv thaiv qhov kub thiab txias donges kom coj teeb pom kev zoo. Thaum qhov ntsuas kub ntawm lub teeb ua siab loj dhau, qhov kub tiv thaiv DIODE tuaj yeem teb tau sai, yog li tiv thaiv lub teeb LED ntawm thermal kev puas tsuaj.
3, Txhim kho cov qauv tsim thiab cov tswv yim thov
Xaiv Qhov Tseeb Diode tsim nyog: Nws yog qhov tseem ceeb los xaiv cov qauv diode tsim nyog raws li cov kev xav tau ntawm cov kev xav tau hauv lub tsev teeb pom kev ntse. Piv txwv li, rau cov tsav tsheb coj uas xav tau kev ua haujlwm siab thiab muaj kev ntseeg siab, schottky downicy nrog qis rau pem hauv ntej voltage tuaj yeem xaiv tau; Rau cov cim hluav taws xob uas yuav tsum muaj kev tiv thaiv ntau yam, cov khoom ruaj khov thiab siab stability zener diodes lossis TVs dods dodes tau xaiv.
Kev tsim kho Circuities: los ntawm kev ua kom pom cov kev tsim hluav taws xob tsim kho, cov kev tiv thaiv tam sim no ntawm kev teeb pom kev zoo hauv lub tsev ntse tuaj yeem txhim kho ntxiv. Piv txwv li, los ntawm kev sib xyaw ua ke multi - theem tam sim no txwv circuits, ntau qhov kev tiv thaiv tuaj yeem ua tiav rau LED teeb pom kev zoo; Kev siv cov muag muag muag muag hluav taws xob thiab kev tiv thaiv kev tiv thaiv sib txuas yuav txo qhov kev nce qib tam sim no ntawm LED teeb thaum pib- thiab tshaj.
Ntxiv dag zog rau kev tsim cua sov ua kom sov Lub caij no, diode ntim nrog high thermal conductivity thiab tsis xaiv los txhim kho ntxiv cov cua sov dissipation kev ua haujlwm ntawm Diode.
Kev tswj kom txawj ntse: Nrog rau kev txhim kho tshuab iot, ntau dua thiab ntau lub tsev teeb pom kev zoo yog txais kev tswj hwm kev tswj hwm hauv tsev ntse. Los ntawm kev koom ua ke ntse sensors, microcontrollers, thiab lwm yam kev ua haujlwm thiab tam sim no ntawm LED teeb tau, yog li txhim kho qhov ruaj khov thiab kev nyab xeeb ntawm lub teeb pom kev zoo.
