一, lub hauv paus ntsiab lus: qhov pib logic ntawm constant tam sim no thiab tas mus li voltage
Cov tub ntxhais muaj nuj nqi ntawm LED Tsav Tsheb Khoom Siv yog hloov dua tshiab ncaj qha (DC) thiab tsav LED thauj khoom los ntawm Constant hom tam sim no lossis tas mus li voltage hom. Nws txoj kev thev naus laus zis tuaj yeem muab faib ua ob pawg:
Kev tsav tsheb tas li (CC)
Haum rau cov xwm txheej nyob qhov twg LED cov hlaws dai tau txuas nrog cov tso zis tam sim no (xws li 350Ma ± 5%), yog li tiv thaiv cov LED los ntawm overcurrent kev puas tsuaj. Piv txwv li, qee hom cim ntawm linear teeb tau siv {{3} w lub teeb tam sim no nrog kev tawm tam sim no ntawm 1.8A (36 × 0.05A) kom ntseeg tau tam sim no rau txhua lub hlaws.
Tas mus voltage drive (CV)
Haum rau parallel LED modules lossis lub teeb sib zog nrog ua - Tshaj tawm los ntawm cov khoom siv tawm tam sim no los ntawm kev tswj hwm cov zis uas tsis yooj yim (xws li 12v / 24V). Piv txwv li, qee qhov kev ntse me me kev kho lub teeb ci
Kev tswj hwm kev lag luam: High kawg linear teeb feem ntau npaj tau ib qho dual {{hom tsav ntawm "tas mus li voltage + tas mus li tam sim no". Piv txwv li, cov philips Hawj tau pom cov khoom thauj los ntawm cov sensors thiab cia li hloov pauv hom tsav, ntsuas kev nyab xeeb thiab sib npaug.
2, Cov tub ntxhais tseem ceeb: los ntawm kev ntsuas kev ua haujlwm rau kev ua engineering
Kev ua tau zoo ntawm lub hwj chim tsav tau txhais los ntawm ntau yam tsis muaj, thiab cov hauv qab no yog cov cim tseem ceeb thiab teeb tsa logic:
1. Tawm tswv yim / tso tawm voltage sib phim
Cov tswv yim voltage: nws yuav tsum tau phim rau cov qauv network (xws li AC220V hauv Suav teb thiab AC120V hauv cov qauv tsim hluav taws xob (AC100-240V) tuaj yeem txhim kho lub ntiaj teb hloov tau.
Cov Zauv Voltage: Lub Sij Hawm Tshaj Tawm Tam Sim No Yuav Tsum Sib Xws Li Qhov Voltage ntawm Txoj Hlawv LED (xws li 3 lub teeb hlaws rau hauv cov 12v tsav); Lub voltage tas li yuav tsum tau ua ke nrog cov ntsuas hluav taws xob ntawm cov qauv (xws li 24V ± 10% tsav rau 24V lub teeb ib strips).
Cov ntaub ntawv: Txoj kev teeb pom kev zoo linear ntawm lub tsev so ntawm lub tsev so tau txais kev tsav tsheb cais nrog AC220V cov tswv yim thiab DC48V tso zis. Kev rho tawm hluav taws xob tau ua tiav los ntawm kev hloov pauv kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob hluav taws xob thiab ua kom tau raws li ntev} deb ntawm xaim.
2. Hwj chim thiab qhov tseeb tam sim no
Tsim hluav taws xob tsim: Lub zog tsav tsheb yuav tsum muaj ntau dua 20% ntawm tag nrho cov hwj chim load (ib qho 4,W) yuav tsum tau nruab nrog tus tsav ntawm 60W lossis ntau dua los tiv thaiv kev tshaj thiab cua sov.
Tam sim no kev tswj qhov tseeb tam sim no: tam sim no kev hloov pauv ntawm kev tsav tam sim no yuav tsum tsawg dua lossis sib npaug ± 5%. Piv txwv li, qhov teeb pom kev phais mob nyob hauv lub tsev kho mob tau tsav nrog qhov ua kom muaj kev cuam tshuam xim kub ntawm kev pom vim muaj kev hloov pauv tam sim no.
3. Kev ua haujlwm thiab lub zog muaj hwj chim (pf)
Conversion efficiency: Efficient driving (efficiency>88%) tuaj yeem txo cov kauj ruam kub thiab txuas ntxiv lub neej. Piv txwv li, lub mingwei Elg Series Drearchs Technology Recstification Technology, nrog kev ua tau zoo ntawm 92%, haum rau ntawm lub thawv teeb ntsia.
Power factor: Drivers with PF>0.95 tuaj yeem txo cov pa phem hauv lub hwj chim sib tw thiab ua raws li EU ERP cov lus qhia. Ib qho chaw qhia cov ntaub ntawv txoj haujlwm PF =0.99 tsav tsheb, nrog ib xyoos ib zaug txuag ntawm 120000 kWh.
4. Kev tiv thaiv muaj nuj nqi thiab kev ruaj ntseg
Kev tiv thaiv theem pib: Seem-Circusure luv (SCP), OVPOLTage tiv thaiv (ovp), thiab tshaj qhov ntsuas kub (OTP) yog cov haujlwm tseem ceeb. Piv txwv li, ib qho teeb meem tawm sab nraum zoov sab nraum zoov lub teeb ua ke ua ke 150℃dhau ntawm kev kaw hluav taws xob kom hloov kho qhov chaw siab kub.
Kev tiv thaiv kev ua tau zoo: kev tiv thaiv kev tiv thaiv (4KV +), IP67 Dej tsis haum rau cov chaw hnyav. Txoj Kev Nqaum Hav Zoov Ntiaj Teb Chaw Haujlwm tau txais yuav IP68, uas yog resistant rau ntsev tsuag tsuag corrosion thiab muaj lub sijhawm 8 xyoo.
3, Scrario Adapationation: Los ntawm cov kev xav tau rau cov kev daws teeb meem
Muaj ntau qhov sib txawv ntawm qhov yuav tsum tau rau cov tsav tsheb hauv cov xwm txheej sib txawv, thiab cov phiaj xwm kev teeb tsa xav tau:
1. Kev Lag Luam Chaw: Cov xim siab rendering thiab dimming yuav tsum tau
Color rendering index (Ra): Scenes such as clothing stores and art museums require a Ra>90 tsav tsheb, ua ke nrog cov xim siab rendering LED beads, kom rov qab cov xim tseeb ntawm cov khoom.
Ntse Dimming: Cov tsav tsheb uas txhawb Dali, 0-10V, lossis Bluetooth Dimming tuaj yeem ua tiav Scene Linkage. Piv txwv li, chaw yuav khoom siv Dali cov tsav tsheb los kho qhov ci ntawm txhua qhov chaw los ntawm kev tswj hwm lub hauv paus, txuag 30% lub zog.
2. Ib puag ncig hauv tsev: Kev nyab xeeb thiab siv tau
Kev nyab xeeb me me kev nyab xeeb tsim: DC24V Tsav yog nyiam rau cov xwm txheej xws li cov menyuam yaus cov chav thiab chav pw kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob. Piv txwv li, qee yam ntse hauv tsev tau tsim muaj sib nqus suction qes- hauv overcurrent tiv thaiv thiab ua rau muaj kev phom sij rau cov menyuam yaus uas tau kov nws.
Yooj yim Installation: Lub teeb ci strip nrog kev sib koom ua ke tsav tsheb tuaj yeem ua rau cov txheej txheem kev teeb tsa. Qee hom lag luam tau tsim ib qho "ntsaws thiab ua si" kev tsim qauv ntawm tus neeg tsav tsheb thiab lub cev ua kom zoo, txo lub DIY chaw nres tsheb.
3. Kev lag luam thiab sab nraum zoov: durability thiab kev ntseeg tau
Dav kub tsim: Muaj cov nroj tsuag yuav tsum tau tsav kom hloov mus rau ib puag ncig los ntawm {}} 30}+60 degree. Qee qhov kev cog ntoo hlau cog tau txais txiaj ntsig siab tau txais kev kub siab rau cov khoom siv hluav taws xob nrog lub neej tsav tsheb ntawm 100000 teev.
Tawg pov thawj Daim Ntawv Pov Thawj: Tshuaj, Kev Siv Tshuaj, Kev Siv Tshuaj thiab lwm yam xwm txheej yuav tsum tau ua kom tawg kom tsis txhob muaj cov xwm txheej hluav taws xob los ntawm hluav taws xob. Ib txoj haujlwm roj pab txhawb nqa Atex ntawv pov thawj tsav thiab ua tau raws li cov qauv nruj los ntawm kev tsim kev nyab xeeb rau kev nyab xeeb.
4, cov qauv kev lag luam thiab cov ntawv pov thawj: Cov kab hauv qab zoo
Cov ntawv pov thawj yuav tsum muaj rau Tsav Tsheb Tsav Tsheb Loj hauv cov lag luam thoob ntiaj teb muaj raws li hauv qab no:
Tuam Tshoj: 3C Ntawv Pov Thawj (GB / T 19510.14-2018)
EU: CE Daim Ntawv Pov Thawj (En 61347-2-13)
North America: UL ntawv pov thawj (ul 8750)
Thoob Ntiaj Teb: IEC 62384 (Lub Zog Hluav Taws Xob)
Cov ntaub ntawv: Ib txoj haujlwm linear exported rau Tebchaws Europe tau rov qab los vim tus tsav tsheb tsis ua EMC sim, ua rau muaj ntau dua 2 lab. Kev lag luam yuav tsum qhia cov qauv ntawv pov thawj hauv kev tshawb nrhiav thiab cov theem kev txhim kho kom zam tau tus nqi tom qab.
