Txhua qhov tsis muaj zog hauv qhov system yuav tsum tau kho kom tsim tau lub teeb LED nrog lub neej ntev. Kev xaiv ntawm LED chips, kev tsav tsheb zoo, thiab kev tswj thermal yog qhov tseem ceeb tshaj plaws. Nov yog phau ntawv qhia muaj txiaj ntsig:
1. Kev tswj cua sov yog thawj qhov tseem ceeb.
Thawj qhov ua rau LED tuag yog cua sov. High junction kub txo tus neeg tsav tsheb lub neej thiab ua kom lub teeb lwj (luminous flux txo).
Xaiv lub teeb nrog hlau (aluminium) vaj tse es tsis txhob muab cov yas ntim tag nrho kom ntseeg tau tias qhov kub zoo tshaj plaws.
Ua kom thaj chaw saum npoo av thiab huab cua txav los ntawm kev ntxiv cov vents los yog cov cua txias.
Txhim kho LED strips ntawm txhuas raj.
Txo qhov tsav tam sim no: Thaum tshav kub kub txo qis thaum LEDs ua haujlwm tsawg dua li qhov ntsuas tam sim no.
Siv ntau LEDs ntawm qis tam sim no ntau dua li tsawg dua LEDs ntawm qhov siab tam sim no rau qhov ci ci.
Xyuas kom muaj qhov cua txaus los ntawm kev ua kom lub teeb kom deb ntawm qhov chaw nruj thiab rwb thaiv tsev.
Rau siab -cov ntawv siv fais fab, yog tias ua tau, suav nrog lub kiv cua me me (ua kom txias).
Khaws ib lub qhov muag ntawm qhov kub thiab txias thiab sim ua kom qis li koj tuaj yeem ua tau (qis dua 85℃tsis zoo; qis dua 65℃yog qhov zoo rau kev ua neej ntev).
2. Xaiv tus tsav tsheb LED nrog lub neej ntev
Feem ntau, tus tsav tsheb malfunctions ua ntej LEDs.
Electrolytic capacitoryuav tsum zam txij li thaum lawv qhuav qhuav. Siv passive LED tsav tsheb (tsuas yog cov resistors, inductors, thiab capacitors) lossis nrhiav cov tsav tsheb ua tsis muaj electrolytic capacitors(sivkhoom capacitorslos yog zaj duab xis capacitors).
Ua haujlwm tas li- cov tsav tsheb tam sim no kom txo qis kev nyuaj siab ntawm LEDs los ntawm kev muab cov khoom tam sim no. Tsuas yog nrog qhov tsim nyog tam sim no - txwv cov resistors tuaj yeem siv tas li - cov tsav tsheb voltage.
Ntxiv kev tiv thaiv: Tus neeg tsav tsheb lub neej yog nce los ntawm kev tiv thaiv surge (MOV lossis TVS diode), kev tiv thaiv overvoltage, thiab kev tiv thaiv overtemperature.
Xaiv qhov siab -qhov zoo: Cov neeg tsav tsheb nrog lub neej nyob ntawm 50,000–100,000 teev (ntawm qhov ntsuas kub) yog qhov zoo tagnrho.
Meanwellcoj tus tsav tsheb yog qhov zoo heev, peb tau siv meanwell rau ntau lub teeb coj, nws ua haujlwm zoo heev, lub neej ntev thiab kev ua haujlwm ruaj khov.
3. Siv High -End LED Chips
Tsis yog txhua qhov LED yog tsim sib npaug. Tsawg- cov nqi chips sai sai poob lumen thiab muaj qhov ua siab ntev kub.
Hom: Nichia, Cree, Osram, Philips Lumileds, Samsung, lossis Seoul Semiconductor yog nyiam.
Txhawm rau txhim kho cov cua sov ua kom zoo dua qub, siv cov tooj liab txhuas es tsis yog hlau.
Rau kev sib txuas hluav taws xob muaj zog thiab tiv thaiv corrosion, siv cov hlau kub.
Siab -lub zog LEDs nrog cov khoom siv ceramic yog qhov zoo tshaj li PCB- raws li ntim.
Lumen txij nkawm: Ntawm qhov ntsuas qhov sib txuas, nrhiav L70 qhov ntsuas siab dua lossis sib npaug li 50,000 teev (lossis Ntau dua lossis sib npaug li 100,000 teev).
Tsawg thermal tsis kam: Xaiv cov LEDs uas tsis muaj kev sib tshuam - mus rau -cov ntaub ntawv thermal resistance, los yog Rθj-c.
4. Txhim kho Circuit Court tsim
Rov qab voltage yuav tsum tsis txhob ntau tshaj 5 V; Yog tias tsim nyog, siv lub diode tiv thaiv.
Siv qhov ua haujlwm tas mus li -tam sim no Circuit Court lossis resistor rau kev txwv tam sim no.
Tsim ib lub voj voog uas cia li txo qis tam sim no thaum qhov kub nce siab tshaj qhov pib. Qhov no yog hu ua thermal foldback.
5. Ua raws li cov kev coj ua zoo
Kev tiv thaiv ESD: LEDs tau raug hluav taws xob zoo li qub. Siv cov tshuaj tiv thaiv- ntim khoom zoo li qub, lub dab teg, thiab cov chaw ua haujlwm hauv av.
Moisture rhiab heev: Yog tias LEDs tau khaws cov dej noo, ci lawv ua ntej reflow soldering (raws li MSL ntsuas).
Sulfur tsis kam: Txhawm rau kom tsis txhob muaj nyiaj plating los ntawm corroding vim sulfur, tog twg los khi lub fixture los yog siv LEDs uas yog cais raws li sulfur-resistant nyob rau hauv tej yam kev mob.
Kev kuaj kev laus: txhawm rau txheeb xyuas cov teeb meem thaum ntxov, khiav teeb ua tiav rau 24 txog 48 teev ua ntej xa khoom.
6. Txhim kho thiab siv kom raug
Kev tu tsis tu ncua yog tsim nyog vim tias cov plua plav paug ua haujlwm zoo li thermal rwb thaiv tsev.
Siv cov dimmers tsim nyog: Tsuas yog cov dimmers uas tsim los ua LED- sib xws yuav tsum tau siv. Flickering thiab ntxov tsis ua hauj lwm yog tshwm sim los ntawm incompatible dimmers.
Kev ruaj ntseg input voltage: Siv tus tsav tsheb nrog ntau qhov kev tawm tswv yim dav (xws li 90-305 V AC) lossis nruab ib qho kev tiv thaiv hluav taws xob hauv cheeb tsam uas qhov hluav taws xob surges tshwm sim.
Khaws cov khoom seem kom raug: Khaws cov LEDs ntxiv rau hauv qhov chaw txias, qhuav hauv cov hnab ntim khoom tiv thaiv- zoo li qub nrog cov desiccant. koj tuaj yeem pom ntev lifespan coj teeb rauhttp://www.benweilight.com
