Dab tsi yog LED tsav tsheb
LED tsav tshebyog ib qho kev tswj hwm thiab cov khoom siv hluav taws xob siv los "tsav" kev ua haujlwm ntawm LED lub teeb strips. Zoo li ib txwm transformers, lawv hloov AC mains voltage (240V AC) rau hauv qis voltage. Txawm li cas los xij, LED tsav tsheb kuj tseem tuaj yeem hloov lub zog hluav taws xob thiab tam sim no mus rau qhov tam sim no tsis tu ncua (DC) xav tau los ntawm LED. LED sawb yuav hloov pauv thaum lub sijhawm cua sov, thiab tus neeg tsav tsheb tuaj yeem kho cov zis raws li cov khoom siv hluav taws xob ntawm LED sawb, yog li tswj hwm lub zog hluav taws xob rau LED mus rau qhov tsis tu ncua 12VDC lossis 24VDC voltage.
Vim yog qhov yuav tsum tau muaj lub zog DC tas li ntawm 12V lossis 24V rau LEDs, txhua lub tshuab LED yuav tsum muaj cov tsav tsheb LED (tshwj tsis yog rau cov tsim tshwj xeeb rau kev tswj hwm los ntawm lub zog hluav taws xob).
Puas yog txhua lub teeb LED xav tau tsav tsheb?
Txhua lub teeb ci LED yuav tsum txuas nrog cov tsav tsheb. Qhov tshwj xeeb tsuas yog tsim tshwj xeeb rau cov teeb pom kev zoo LED tswj los ntawm cov khoom siv hluav taws xob, xws li cov teeb pom kev hauv lub teeb lossis LED qhov muag teev.
Tsav hom
Muaj ob hom LED tsav tsheb sib txawv: tsis tu ncua voltage LED tsav tsheb thiab cov tsav tsheb tam sim no tsis tu ncua, uas muaj cov haujlwm sib txawv thiab kev siv.
Tus tsav tsheb tam sim no tsis tu ncua yog tsim tshwj xeeb rau LEDs uas yuav tsum tau muaj tam sim no tab sis tuaj yeem tiv taus qee qhov voltage ntau. Lawv lub hauv paus ntsiab lus ua haujlwm yog hloov qhov hluav taws xob muab rau lub teeb ci kom tswj tau qhov tam sim no tsis tu ncua. Vim nws muaj peev xwm tswj tau tam sim no, cov tsav tsheb tsis tu ncua tam sim no yog qhov tsim nyog tshaj plaws rau LED raj teeb lossis lub zog siab LEDs.
Tus tsav tsheb tsis tu ncua yog tsim rau LED teeb uas yuav tsum muaj qhov ruaj khov (12V lossis 24V tsav tsheb) tab sis tam sim no tau tswj hwm los ntawm lwm yam khoom siv kev nyab xeeb xws li resistors. Cov tsav tsheb no yog qhov tsim nyog tshaj plaws rau LED teeb uas xav tau qhov hluav taws xob tas li kom muaj xim ci.
Qhov voltage yog dab tsi?
Txhua lub teeb ci LED yuav tsum muaj 12V lossis 24V voltage mov, uas tuaj yeem pom hauv cov khoom specifications. Thov nco ntsoov yuav tus tsav tsheb nrog tib qhov tso zis hluav taws xob raws li lub teeb sawb. Siv tus tsav tsheb 24V los tsav lub 12V lub teeb sawb yuav ua rau lub teeb ci LED tig rau lub sijhawm luv luv, ua rau muaj hluav taws xob ntau dua hluav taws xob tawm ntawm lub teeb ci. Siv tus tsav tsheb 12V los tsav lub 24V lub teeb sawb yuav ua rau cov teeb ci LED tsis teeb txhua.
wattage yog dab tsi?
Lub zog noj ntawm LED strips txawv nyob ntawm lawv qhov ntev. Lub wattage (W) ntawm lub teeb sawb hais txog lub zog siv ib 'meter' ntawm lub teeb sawb. Txhawm rau xam qhov xav tau wattage ntawm daim kab xev, tsuas yog muab cov wattage ntawm daim kab xev los ntawm tus lej ntawm kev ua haujlwm. Piv txwv li, ib tug 6-meter ntev 6-watt LED sawb yuav tsum tau 30 watts. Peb pom zoo kom siv tus neeg tsav tsheb nrog lub zog tso zis ntawm 33W lossis siab dua los ua lub zog rau hom teeb ci no.
Tom qab paub lub zog ntawm lub teeb sawb, koj tuaj yeem xaiv tus tsav tsheb tsim nyog. Lub hwj chim ntawm tus neeg tsav tsheb sawv cev rau nws lub peev xwm tso zis ntau tshaj plaws. Peb pom zoo xaiv cov tsav tsheb uas muaj lub zog tsawg kawg yog 10% siab dua li qhov xav tau lub zog rau LED strips kom ntseeg tau lub neej ntev.
Kev sib raug zoo yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kev ua haujlwm ntawm LED tshuab thaum xaiv cov tsav tsheb tsim nyog LED. Kev siv cov tsav tsheb tsis raug tuaj yeem ua rau lub cev tsis ua haujlwm thiab ua rau cov khoom puas.
Ntawm LGDD, peb muab ntau yam LED tsav tsheb kom tau raws li ntau yam kev xav tau, suav nrog 12V / 24V xaiv, cov qauv dimmable, tsim tsis muaj dej, thiab cov tsav tsheb zoo Mean Well. Raws li ib qho ntawm cov neeg ua haujlwm ntev tshaj plaws thiab cov neeg muag khoom tshaj lij nyob hauv Suav teb, peb pab pawg kws tshaj lij yuav coj koj los xaiv tus tsav tsheb uas haum rau koj cov kev xav tau tshwj xeeb, kom ntseeg tau tias koj cov teeb tsa LED ua tiav qhov kev ua tau zoo thiab kev ntseeg tau.
