Hauv kev tsim lub teeb pom kev zoo rau cov qaib ua liaj ua teb, qhov kev xaiv ntawm 48V ncaj qha tam sim no (DC) lossis 220V alternating tam sim no (AC) powered LED teeb yuav tsum tau txiav txim siab txog kev nyab xeeb, kev siv hluav taws xob, kev teeb tsa tus nqi, kev saib xyuas thiab cov yam ntxwv ntawm cov nqaij qaib. Cov hauv qab no yog cov kev txheeb xyuas tseem ceeb thiab cov lus pom zoo:
1. Kev nyab xeeb: 48V DC muaj qhov zoo
Tsawg pheej hmoo ntawm hluav taws xob poob siab:
Lub tsev qaib lub tsev ib puag ncig yog ntub dej (tsis tu ncua siab - yuav tsum tau siv rab phom tua dej), thiab 48V DC belongs rau kev nyab xeeb ntxiv tsis muaj hluav taws xob (SELV), yog li tsis muaj kev pheej hmoo ntawm hluav taws xob poob txawm tias muaj kev sib cuag ncaj qha.
Txawm li cas los xij, 220V AC muaj kev pheej hmoo siab ntawm kev xau hauv qhov chaw ntub dej thiab yuav tsum muaj kev tiv thaiv ntxiv (xws li IP66 qib), uas ua rau cov nqi nce thiab qhov nyuaj.
Kev tiv thaiv cov cuab yeej yooj yim:
48V DC lub teebtsis tas yuav tsum muaj kev tiv thaiv hauv av, txo kev nyab xeeb kev phom sij tshwm sim los ntawm kab tsis raug.
2. Kev siv hluav taws xob thiab kev tsim hluav taws xob: txhua tus muaj nws qhov zoo thiab qhov tsis zoo
48V DC qhov system:
Kev poob qis: Tsav ncaj qha rau LEDs kom tsis txhob siv hluav taws xob los ntawm ntau yam AC -DC hloov dua siab tshiab (tseem siv AC teeb yuav tsum tau kho thiab txo qhov hluav taws xob, nrog kev ua haujlwm poob ntawm 5-20%).
Qhov tseeb dimming: DC dimming tsis muaj flicker, tsis txhob muaj kev ntxhov siab hauv cov nqaij qaib. Cov kev sim qhia tau hais tias LED dimming tuaj yeem ua tau raws li qhov yuav tsum tau muaj teeb pom kev zoo ntawm kev tso hens ntawm ntau theem kev loj hlob thiab txhim kho qe kev ruaj ntseg.
220V AC qhov system:
Suitable for high-power scenarios: If the power of a single lamp is >1500W (xws li teeb pom kev hauv nruab nrab hauv lub tsev qaib loj), 220V AC tuaj yeem txo cov kab tam sim no thiab kev sib kis.
Qhov zoo ntawm high-voltage LEDs: Tshiab siab-voltage LEDs (xws li 50V ib qho chips) tuaj yeem txo AC-DC voltage sib txawv thiab txhim kho kev hloov pauv, tab sis ntawm tus nqi siab dua.
3. Kev txhim kho thiab tu: 48V DC yog yooj yim dua
Simplified kab:
48V DC lub teebfeem ntau txais yuav cov qauv tsim, nrog cov dej tsis sib txuas ncaj qha ntawm cov teeb, tsis tas yuav muaj kev ywj pheej thaiv, thiab kev tsim kho kev ua haujlwm raug txo qis (xws li lub Hoobkas ua ntej - nruab rau hauv ib txoj hlua ntawm lub teeb raj).
220V AC xav tau cov kab hluav taws xob, uas ua rau cov nqi hluav taws xob nce ntxiv thiab kev nqis peev hluav taws xob.
Tus nqi kho mob qis:
Lub 48V DC system muaj qhov tsis ua haujlwm tsawg, thiab lub zog dimming (xws li 2000W fais fab mov) txhawb nqa overheating tus kheej- rov qab thiab muaj lub neej ntev txog 3 xyoos;
Yog tias tus tsav tsheb ntawm 220V AC lub teeb puas lawm, tus nqi hloov pauv yog siab (xws li Philips dimming modules xav tau cov khoom siv tshwj xeeb).
4. Kev ua haujlwm ntawm nqaij qaib: ob qho tib si siv tau, tab sis kev ua haujlwm dimming yog qhov tseem ceeb
Kev hloov kho spectrum thiab siv zog:
Txawm li cas los xij48V DC los yog 220V AC, LED teeb tuaj yeem ua tiav 3000K lub teeb daj (rau nteg hens) lossis 6500K dawb lub teeb (rau broilers), thiab txhawb 0-100% dimming.
Lub tshuab ntse tuaj yeem simulate hnub sawv thiab hnub poob, txo cov nqaij qaib kev ntxhov siab, thiab nce qe ntau ntxiv los ntawm 5-10%.
Tsis xav tau flicker:
DC fais fab mov yog ib txwm flicker -dawb, thaum AC teeb yuav tsum siab - tsav tsheb zoo kom tsis txhob flicker (cov khoom tsis zoo tuaj yeem ua rau pecking hauv qaib).
5. Pom zoo cov xwm txheej siv tau
48V DC yog qhov zoo dua:
Me thiab nruab nrab-cov tsev qaib loj (tag nrho lub zog Tsawg dua lossis sib npaug li 2000W);
Cov tsev uas xav tau kev dimming ntau heev los yog cov av noo siab;
Cov xwm txheej uas hais txog qhov ntev - lub sij hawm txuag hluav taws xob thiab kev nyab xeeb (xws li lub sij hawm tso hens nteg).
Xav txog 220V AC:
Loj -scale centralized teeb pom kev zoo (ib lub voj voog> 1500W);
Muaj ib qho kev faib hluav taws xob AC uas twb muaj lawm thiab cov peev nyiaj kho dua tshiab tau txwv.
48V DC kev daws teeb meem yog ntau dua nyob rau hauv raws li cov kev xav tau ntawm niaj hnub qaib ua liaj ua teb, tshwj xeeb tshaj yog nrog rau qhov zoo ntawm xoom kev nyab xeeb kev pheej hmoo, meej dimming, thiab ntev - lub sij hawm txuag hluav taws xob, nws tau dhau los ua lub ntsiab. Piv txwv li, Shandong Suiguang's DC48V system (lub teeb raj + ntse dimming lub thawv) tau ua tiav "kev nyab xeeb voltage + programmed teeb pom kev zoo", nrog rau cov txiaj ntsig tseem ceeb. Yog tias lub tsev qaib qub muaj AC fais fab kev faib tawm thiab tsis xav tau qhov dimming zoo, siab -voltage LED 220V AC teeb tuaj yeem siv los ua cov kev hloov pauv hloov pauv, tab sis ya raws- pov thawj thiab kev tiv thaiv hauv av yuav tsum tau ua nruj me ntsis. Qhov kev txiav txim zaum kawg tuaj yeem ua raws li qhov ntsuas ntawm kev yug me nyuam, pob nyiaj siv thiab qib kev txawj ntse, thiab xa mus rau cov chaw tsim khoom cov kev daws teeb meem (xws li BENWEI, Philips) rau kev tsim kho, koj tuaj yeem paub cov ntaub ntawv ntau ntxiv ntawm http://www.benweilight.com
