Peb yuav tsim lub teeb nyob mus ib txhis rau peb lub xov tooj cua transistor.

Khoom siv

Dawb LED diode 10mm, thawj lub teeb uas tsis ua haujlwm nrog E10 xov, tiv thaiv, hloov pauv laum, solder, tin.

Kauj Ruam 1: Kev Npaj Lub Cev Lub Cev

Ua tib zoo nqa lub teeb mus rau hauv lub pliers thiab tsoo lub iav.

Kauj Ruam 2: Tshem Tawm Sab Hauv Phem Hauv Lub Tes Tsho

Tshem Tawm Sab Hauv Phem Hauv Lub Tes Tsho

Siv lub pliers, maj mam nias lub tes tsho nyob ib ncig kom txog thaum cov av sab hauv xws li iav thiab kua nplaum tawg.

Kauj Ruam 3: Drilling Qhov Rau Cheeb Tsam

Tshem cov tshuaj txhuam hniav hauv qab ntawm lub tes tsho. Tom qab ntawd peb laum 1mm qhov nyob hauv qab thiab sab raws li daim duab, ntawm no peb yuav xov xov tivthaiv ua.

Ib tus tiv thaiv series yuav tsum tau tiv thaiv cov diode los ntawm qhov tsis raug hluav taws xob. Nws tus nqi nyob ntawm qhov muab hluav taws xob ntawm lub teeb qub thiab qhov tam sim no ntawm cov diode xaiv. Piv txwv li, kuv cov diode yog dawb nrog 3.6V qhov ntsuas thiab tam sim no ntawm 20mA thiab cov khoom siv hluav taws xob yog 9V. Muaj ntau lub laij lej online hauv Is Taws Nem rau kev suav qhov tsis kam, tab sis nws yog qhov kev suav yooj yim. Rho tawm qhov ua haujlwm ntawm LED los ntawm qhov hluav taws xob nkag thiab faib qhov tshwm sim los ntawm diode tam sim no hauv amperes.

R = Uz -Uf/I (Uz - input voltage, Uf - LED diode ua haujlwm voltage, I - LED diode ua haujlwm tam sim no)

R = 9-3.6 / 0.02 (R = 9V - 3, 6V / 0.02A) = 270 (Ω)

Qhov tshwm sim resistor tsis kam yog li 270 ohms. Peb txuas lub resistor rau ib lub davhlau ya nyob twg diode.

Xov xov tivthaiv ua los ntawm rooj plaub thiab cov laug. Thaum kawg, peb tsuas yog kho txoj haujlwm diode ntawm lub qhov (socket). Koj tuaj yeem thov cov kua nplaum me me hauv qab LED vaj tse rau lub qhov (socket) rau kev txhawb nqa.

Peb tuaj yeem txuas lub teeb ua tiav rau hauv xov tooj cua. Nco ntsoov qhov sib txawv ntawm qhov hluav taws xob, hauv qee kis koj yuav tsum pauv cov xov hluav taws xob nyob hauv qab tus tuav lub teeb. Kuv tau pom tias qhov muag teev ntawm qee lub xov tooj cua desktop tau siv los ntawm AC qhov hluav taws xob ncaj qha los ntawm kev hloov pauv. Qhov ntsuas hluav taws xob no tsis haum rau LED diode, yog li nws yog qhov tsim nyog yuav tsum suav nrog lub kho hluav taws xob nrog lub tshuab ua kom sib luag ntawm LED diode thiab hloov pauv. Peb ntsuas qhov tshwm sim qhov hluav taws xob thiab suav qhov tsis kam ua raws li qhov tshwm sim.

Ceev faj, Ua haujlwm Tsuas yog QHOV TSEEB QHOV TSEEB, QHOV TSEEB RAU 12V. Kuv tsis yog lub luag haujlwm rau txhua qhov kev raug mob los ntawm tus txheej txheem IMPROPER.

PS Thov txim kuv cov lus Askiv tsis zoo:)
