Phau ntawv qhia pib ua rau koj tus kheej lub phiaj xwm teeb pom kev zoo siv LED sawb.
Saj zawg zog txhim khu kev qha thiab siv tau yooj yim, LED strips yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv.
Kuv yuav npog qhov pib ntawm kev teeb tsa yooj yim sab hauv tsev 60 LED's/m LED sawb, tab sis cov lus qhia yuav siv feem ntau nrog lwm hom kab txaij ntawm LED.
Kauj Ruam 1: Txiav LED Sawb
Feem ntau cov hlua LED tuaj nrog cov xov txuas ua ntej lossis cov txuas tshwj xeeb. Tab sis yog tias koj xav siv tsuas yog qhov ntev tshwj xeeb ntawm kab txaij koj yuav tsum paub qhov twg koj tuaj yeem txiav.
Txhua lub strips LED muaj cov ntsiab lus tshwj xeeb uas koj tuaj yeem txiav. Cov ntsiab lus no feem ntau yog cim nrog kab hla kab ntawv thiab qee qhov txuas tooj liab (ntawm qee daim ntawv koj tuaj yeem pom tus cim txiab).
LED sawb tuaj yeem raug txiav siv txiab txiab.
TSIS TXHOB txiav lwm qhov tab sis kab cim. Yog tias koj txiav cov hlua hauv lwm qhov chaw koj tuaj yeem xaus nrog qee qhov LED hauv thaj chaw txiav tsis ua haujlwm.
LED strips yog tus kheej nplaum. Tev tawm txheej tiv thaiv sab nraub qaum thiab koj tuaj yeem lo nws ntawm iav, hlau, yas, feem ntau cov ntoo tiav.
Kauj Ruam 2: Txuas LED Strips
LED strips tuaj yeem txuas nruab nrab ntawm lawv nrog cov khoom siv sib txuas.
Ntsuas thiab txiav cov xov hlau (qauv xim yog RED rau qhov zoo thiab BLACK rau qhov tsis zoo).
Seem cov xov hlau ntawm ob qho kawg nrog lub tshuab txiav, lossis cov hlua hlau yog tias koj muaj.
Kuv xav kom ua ntej soldering ob lub xov hlau thiab tooj liab sib txuas ua ntej ua qhov kawg soldering.
Tam sim no muab cov hlau liab tso rau ntawm qhov zoo (+ cim) tooj liab txuas thiab ib qho dub ntawm qhov tsis zoo txuas (- cim).
Thaum kawg ntawm lub voj voos txuas ob lub xov hlau ntev dua rau lub zog LED sawb.
Kauj Ruam 3: Ua kom lub LED Sawb
Txhawm rau ua kom lub ntsej muag LED koj yuav xav tau Cov Khoom Siv Hluav Taws Xob uas tuaj yeem muab lub zog txaus rau qhov ntev ntawm LED sawb koj yuav pom kev.
Cov khoom siv hluav taws xob feem ntau ntsuas hauv AMPS thaum cov hlua LED tau ntsuas hauv WATTS. Txhawm rau hloov lawv koj tuaj yeem siv cov qauv no: A (amps) x V (volts) = W (watts) lossis W / V = A.
Kuv cov hlua LED tau ntsuas ntawm 24W/5m. 24W / 5m = 4.8 W / m.
Yog li yog tias koj xav siv 8m ntawm kab txaij uas txhais tau tias 4.8W x 8m = 38.4 W
Siv cov lej hloov pauv kuv tuaj yeem paub ntau npaum li cas Amps kuv nead. W / V = A --- 38.4W / 12 V = 3,2A
Nws raug nquahu kom siv lub zog siab dua ntsuas Lub Hwj Huam Fais Fab ntau dua li qhov xav tau tiag tiag (10% - 20% siab dua)
Rau kuv tus piv txwv kuv yuav siv 5A Lub Hwj Chim Pupply.
Hauv kuv qhov haujlwm kuv yeej siv 20 AMP Lub Hwj Huam Siv nrog cov khoom siv sib txuas (3 kev sib txuas rau 220V cov tswv yim thiab 2 teeb ntawm 2 txuas rau 12V tso tawm).
Cov tswv yim sib txuas yog rau GROUND (ntsuab/daj), N thiab L (xim av thiab xaim xaim).
Cov kev sib txuas tso tawm yog qhov uas ob lub xov hlau ntev los ntawm LED sawb mus (RED ntawm qhov zoo thiab BLACK ntawm qhov tsis zoo).
KAWG !!! Plug rau hauv Lub Hwj Chim thiab txaus siab rau lub teeb:).
