Lub hwj chim muab rau hauv LED qhov muag teev yog tsim los kom muaj chaw nyob tsawg kawg hauv lub teeb thiab tib lub sijhawm kom ntseeg tau tias muaj hwj chim tshaj plaws. Qhov txuas tsis muaj zog tshaj plaws hauv cov saw hlau feem ntau yog hluav taws xob capacitor nrog lub zog ua haujlwm ntawm 400V. Qhov puas capacitor feem ntau yog inflated thiab pom kev puas tsuaj.

Tom qab ntawd, ib tus tuaj yeem nug, ua cov teeb LED puas muaj cov capacitors?

Capacitors feem ntau yog siv hauv LED cov tsav tsheb kom ua kom du thiab txo qhov ripple los ntawm cov khoom siv hluav taws xob. Xaiv txoj cai capacitors rau LED teeb pom kev zoo cov txheej txheem pab tiv thaiv kom tsis txhob flickering, tshem tawm cov cua sov ntau dhau, thiab ua kom lub neej nyob ntev LED teeb.

Ib tus kuj yuav nug, LED twg yog siv rau hauv qhov muag teeb? Lub ntsiab LED cov ntaub ntawv Cov ntaub ntawv tseem ceeb semiconductor siv los tsim LEDs yog: Indium gallium nitride (InGaN): xiav, ntsuab thiab ultraviolet high-brightness LEDs. Aluminium Gallium indium phosphide (AlGaInP): daj, txiv kab ntxwv thiab liab high-brightness LEDs. Aluminium gallium arsenide (AlGaAs): liab thiab infrared LEDs.

Tsis tas li ntawd, yog lub teeb qhov muag teev capacitor?

Ua ntej tshaj, nco ntsoov tias lub teeb Nws yog ib qho tseem ceeb tsuas yog ib tug glorified resistor. Raws li tam sim no ntws los ntawm cov ntsiab lus, Joule cua sov ua rau cov ntsiab lus kom kub thiab tso tawm teeb . Txawm li cas los xij, qhov tam sim no yuav txo qis ib yam li capacitor tawm thiab thaum kawg yuav poob rau xoom ntawm qhov taw tes noob yuav tawm mus.

Koj yuav ua li cas LED ntsais nrog lub capacitor?

  1. Kauj ruam 1: Ntxiv cov Transistors. Ntxiv ob PNP transistors thiab jumper xov hlau los ntawm lub zog BUS rau lub tshuab hluav taws xob ntawm txhua lub transistor.
  2. Kauj ruam 2: Ntxiv cov Capacitor.
  3. Kauj ruam 3: Ntxiv 100K Resistor.
  4. Kauj Ruam 4: Ntxiv cov LEDs.
