Thaum ntxuav qhov tsis meej pem hauv kuv lub rooj cob qhia kuv pom ib lub teeb uas tawg lawm. Kuv xav kho nws, tab sis thaum kuv qhib nws tsis muaj dab tsi los kho, lub teeb tawg thiab kuv txiav txim siab ua lub teeb LED tshiab rau nws… thiab rau qhov uas yuav yog kuv tom ntej (thawj) Qhia. Xav kom kuv muaj hmoo. Nyob0falsefalsefalseEN-USX-NONEX-NONEMicrosoftInternetExplorer4

CEEV FAJ !!!! Txoj haujlwm no cuam tshuam nrog qhov hluav taws xob siab txaus uas yuav tsum tsis siv yog tias koj tsis muaj kev paub dhau los. Kuv tsis ua txhaum yog tias koj ntawm lwm tus neeg raug mob ua qhov no.

Kauj ruam 1: Circuit Court

Kuv xav paub yuav ua li cas ntsaws LED diode uas ua haujlwm ntawm 1, 2V DC ntawm qhov hluav taws xob tseem ceeb ntawm 220V AC, thiab cov lus teb tau yooj yim… zener diode… Nws ua haujlwm li cas: Tam sim no dhau los ntawm F1 uas yog 100mA 250V fuse. Tom qab ntawd AC qhov hluav taws xob tau hloov pauv mus rau DC los ntawm tus choj txuas hluav taws xob BR1, thiab tam sim no dhau los ntawm R1, R2 uas txuas nrog ua ke yog li sib hlub tam sim no los ntawm lawv, thiab ua rau lawv sov dua. Qhov hluav taws xob tau ruaj khov los ntawm D1 uas yog 10V 0.5W zener diode thiab qhov hluav taws xob tom qab siv los ua lub zog LED (s). Kuv siv 2 LED ib qho liab, thiab ib qho xiav thiab cov txiaj ntsig tau zoo (koj tuaj yeem pom nws ntawm thawj, thiab nplooj ntawv kawg) Kuv tsis tau tsim PCB txog qhov haujlwm no, vim tias koj yuav xav tau los ntawm koj tus kheej xav tau nyob ntawm seb koj yuav muab tso rau qhov twg. Raws li koj tau nyeem hauv thawj nplooj ntawv qhov haujlwm no yog qhov txaus ntshai, yog li thov thaum koj yuav siv qhov no tso rau hauv qee lub thawv yas kom koj, lossis lwm tus neeg yuav tsis raug hluav taws xob nrog lub teeb.

Kauj ruam 2: R3

R3 nyob ntawm seb muaj pes tsawg LED (koj) siv. Koj yuav tsum tau suav nws los ntawm cov qauv hauv qab no. R = (Uz-Uled)/IP = U*IUz-Voltage ntawm zener diodeUled-Ua haujlwm voltage ntawm LED diodeI ~ 10mA (tam sim no uas dhau los ntawm LED) P-Power ntawm tus tiv thaiv (Kuv paub tseeb tias tus tiv thaiv xav tau yuav kuv 1/4W, tab sis kuv yuav qhia koj kom suav lub zog)

Lub teeb tau ua nws txoj haujlwm zoo heev uas yog teeb pom kev hauv chav thaum txhua lub teeb raug kaw yog tias koj xav mus hauv chav dej thiab hloov chaw koj ua tiav hauv tsev kho mob, vim tias koj dawm ntawm cov khoom ua si uas tshwm sim nyob ntawd. Nov yog ob peb daim duab ntawm cov khoom ua tiav Thiab rau qhov kawg (qhov no yog qhov kawg tiag) Ua tsaug rau kev nyeem kuv Cov Lus Qhia, thiab xav tias dawb nug thiab muab qee qhov kev thuam txog kuv Cov Lus Qhia …
