Kev pabcuam lub neej ntawm LED teeb yog cuam tshuam los ntawm ntau yam. Cov hauv qab no yog cov ntsiab lus tseem ceeb tshaj plaws thiab lawv cov txheej txheem ntawm kev ua:
1. LED nti zoo
Cov ntaub ntawv thiab cov txheej txheem
Cov khoom siv semiconductor (xws li GaN, InGaN) thiab cov txheej txheem tsim khoom ntawm cov nti ncaj qha cuam tshuam rau kev ua haujlwm ntawm luminous thiab stability.
High - cov chips zoo tuaj yeem txo cov teeb pom kev zoo (qhov ci ntsa iab) thiab xim sib txawv, thiab lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 50,000 teev, thaum cov chips tsis zoo yuav muaj hnub nyoog loj hauv 10,000-20,000 teev.
Lub teeb lwj ceev
LED lub neej feem ntau txhais tau tias yog lub sijhawm thaum lub teeb ci poob rau 70% ntawm tus nqi pib (L70 tus qauv).
Qhov ceev ntawm lub teeb lwj nyob ntawm qhov kub thiab txias tsis kam ntawm cov nti tam sim no.
2. LED fais fab mov (LED tsav tsheb)
Kev ruaj ntseg tam sim no
LED yog rhiab heev rau tam sim no, thiab lub zog tsav tsheb yuav tsum muab cov zis tam sim no. Kev hloov pauv tam sim no lossis tsis ruaj khov voltage tuaj yeem ua rau cov nti ua kom sov lossis hlawv.
Tsis zoo-cov khoom siv hluav taws xob tsis zoo yog qhov ua rau siab - zaus pulses lossis harmonics, uas ua rau cov khoom ua kom muaj kev laus.
Conversion efficiency
High-cov khoom siv hluav taws xob ua tau zoo (Ntau dua lossis sib npaug li 90%) tuaj yeem txo qis zog thiab tsim hluav taws xob thiab txuas ntxiv lub neej tag nrho.
Cov khoom siv hluav taws xob tsis zoo ua kom muaj cua sov siab, uas yuav ua rau muaj teeb meem xws li capacitor bulging thiab Circuit Court ablation.
3. Thaum tshav kub kub dissipation tsim
Thermal tswj qauv
Qhov sib txuas kub ntawm LED chips yog qhov taw qhia tseem ceeb. Rau txhua txhua 10℃nce, lub neej ncua yuav raug halved.
High-cov teeb zoo sai sai sai tshem tawm cov cua sov los ntawm aluminium substrates, lub dab dej kub, cov roj thermal, thiab lwm yam.
Ambient kub
Qhov kub thiab txias ib puag ncig (xws li cov teeb kaw thiab sab nraum zoov thaum lub caij ntuj sov) yuav ua rau cov cua sov sib xyaw ua ke thiab ua kom lub teeb tawg.
Pom zoo ua haujlwm kub:-20 ° ~ 40 ° C(kev tsim tshwj xeeb yog xav tau yog tias nws tshaj qhov ntau). BENWEI tuam txhab tuaj yeem tsim-20℃~ 55℃kub kub LED teeb
4. Siv ib puag ncig thiab txoj kev teeb tsa
Humidity thiab hmoov av
Qhov chaw ntub dej tuaj yeem yooj yim ua rau luv luv Circuit Court lossis xeb ntawm cov hlau (xws li oxidation ntawm lub teeb hlaws solder pob qij txha).
Plua plav tsub zuj zuj yuav thaiv cov cua kub dissipation qhov thiab tsim cov cheeb tsam kub kub.
Qhov chaw teeb tsa
Cov teeb uas nyob ze (xws li cov teeb hauv qab thiab cov teeb ci qab nthab) yuav tsum tau khaws cov cua sov kom tsis txhob nyob ze ntawm lub qab nthab lossis phab ntsa.
Sab nraum zoov teeb yuav tsum muajIP65thiab saum toj no waterproof thiab dustproof ntsuam xyuas.
5. Cov cwj pwm siv
Hloov zaus
Kev hloov pauv tsis tu ncua (xws li kaum ob zaug hauv ib hnub) tuaj yeem ua rau lub neej ntawm tus neeg tsav tsheb luv vim qhov kev poob siab tam sim no, tab sis LED nti nws tus kheej muaj kev tiv thaiv siab rau lub sijhawm hloov (feem ntau txog 50,000 zaug lossis ntau dua).
Lub sijhawm ua haujlwm tsis tu ncua
Ntev -lub sij hawm 24-teev kev siv tsis cuam tshuam yuav ua rau lub teeb tawg. Nws raug nquahu kom siv nwstsis pub ntau tshaj 12 teev ib hnub twg.
Lub tuam txhab Benwei tuaj yeem tsim lub sijhawm ntev -24-teev tsis cuam tshuam nrog LED teeb
6. Lwm yam
Cov ntaub ntawv ntim khoom
Yog tias cov epoxy resin lossis pob silicone muaj cov huab cua tsis zoo, nws yooj yim rau daj thiab tawg, ua rau cov nti raug thiab puas.
Kev tsim Circuit Court
Overvoltage/overcurrent tiv thaiv thiab tiv thaiv- zoo li qub tsim (ESD) tuaj yeem tiv thaiv qhov hluav taws xob tsis sib xws los ntawm kev puas tsuaj rau LED.
Hom thiab ntawv pov thawj
Cov khoom uas tau dhau LM-80 (lub teeb lwj kuaj), UL, thiab CE daim ntawv pov thawj muaj kev ntseeg siab dua.
Cov tswv yim tswv yim rau kev ncua lub neej ntawm LEDs
Xaiv cov khoom zoo -cov npe zoo: muab qhov tseem ceeb rau cov khoom lag luam loj xws li Philips, Osram, thiab CREE.
Ua kom pom tseeb ntawm kev tsim cov cua sov: tsis txhob siv siab - lub zog LED teeb hauv qhov chaw kaw.
Kev ruaj ntseg fais fab mov ib puag ncig: nruab ib lub zog stabilizer lossis UPS (tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj qhov hloov pauv loj).
Kev tu thiab tu tsis tu ncua: tshem cov plua plav tawm ntawm qhov chaw ntawm lub teeb thiab xyuas seb cov khoom siv hluav taws xob puas zoo li qub.
Kev siv tus cwj pwm tsim nyog: txo qis kev hloov pauv ntau zaus thiab zam kev ua haujlwm ntev - nyob rau hauv siab - qhov kub thiab txias.
Los ntawm kev ua kom zoo dua cov ntsiab lus saum toj no, lub neej tiag tiag ntawm cov teeb ci LED tuaj yeem mus txog lossis txawm tias dhau ntawm tus nqi nominal (xws li 50,000 teev ≈ 5.7 xyoo, xam raws li 24 teev hauv ib hnub), uas yog qhov zoo dua li cov teeb pom kev zoo (kwv yees li 1,000 teev) thiab lub zog - txuag teeb (8,000 teev). Yog tias koj xav tau cov khoom zoo (ntev-lub sijhawm 24-teev tsis cuam tshuam) LED Teeb, koj tuaj yeem mus ntsibhttp://www.benweilight.com
