LED vaj huam sib luag teeb 'ntev lifespan, elegant tsim, thiab zog efficiency tau hloov tag nrho cov niaj hnub teeb pom kev zoo. Txawm hais tias cov chaw tsim khoom nquag tshaj tawm lub neej ntawm 50,000 teev lossis ntau dua, qhov kev ua tau zoo yog nyob ntawm ntau qhov sib txawv. Los ntawm kev paub txog cov xwm txheej no, cov neeg siv tuaj yeem txuas ntxiv lawv lub neej thiab tiv thaiv kev ua tsis tiav. Cov yam tseem ceeb uas cuam tshuam rau ibLED vaj huam sib luag teeblub neej raug tshuaj xyuas ntawm no.
LED Chip Zoo
Lub hauv paus ntawmvaj huam sib luag teebyog LED nti. Cov ntaub ntawv semiconductor Advanced siv nyob rau hauv siab - cov chips zoo los ntawm cov tuam txhab txhim khu kev qha (xws li Cree thiab Nichia) lav kev ua haujlwm ruaj khov thiab txo qis lumen degradation. Cov chips ntawm qhov tsis zoo tuaj yeem ua rau poob sai dua, ua rau muaj xim hloov lossis dimming.
Tus qauv L70, uas xam lub sij hawm nws yuav siv sij hawm rau cov zis rov qab mus rau 70% ntawm nws thawj brightness, ntsuas lumen degradation nyob rau hauv LEDs. Txawm hais tias cov chips kim dua yuav tsum tsis ua haujlwm tom qab 25,000 teev, siab -cov chips kawg tuaj yeem nyob twj ywm ci ntsa iab rau 50,000 txog 100,000 teev. Kev ntseeg tau raug lees paub los ntawm kev yuav khoom vaj huam sib luag nrog LM-80-kuaj LEDs, uas tau pom zoo rau kev tu lumen ntawm ntau qhov kub thiab txias.
Kev ua haujlwm ntawm Tus Tsav Tsheb
Tus neeg tsav tsheb ua haujlwm ua lub zog rau LED los ntawm kev tswj qhov voltage thiab tam sim no. Ib tus neeg tsav tsheb tsim tsis zoo nrog subpar capacitors lossis kev tiv thaiv tsis txaus tuaj yeem ua haujlwm tsis zoo thaum ntxov thiab ua rau lub teeb lub neej luv. Cov tsav tsheb uas tsis muaj kev tiv thaiv thermal, piv txwv li, khiav txoj kev pheej hmoo ntawm overheating thiab ua tsis raws cai tam sim no, uas lim LEDs.
Cov neeg tsav tsheb zoo tshaj plaws yog cov uas muaj 10 xyoo lub neej thiab kev ua haujlwm siab. Cov yam ntxwv suav nrog kev hloov kho fais fab (PFC), cov khoom tso tawm tsis tu ncua, thiab ua raws li cov cai tswj kev nyab xeeb (xws li UL thiab CE) yuav tsum tau nrhiav. Xaiv cov qauv tsim qauv ua rau kev kho yooj yim yam tsis muaj kev cuam tshuam tag nrho vim tias cov tsav tsheb feem ntau tsis ua ntej LEDs.
Tswj cua sov
Cov yeeb ncuab ntawm LEDs yog cua sov. Overheating speeds li lumen degradation los ntawm accelerating electron migration hauv semiconductor. Qhov ntsuas kub qis qis yog tswj hwm los ntawm kev tswj xyuas kom zoo, uas tuaj yeem ua tiav nrog cov qauv kev ua kom txias txias, cov dab dej kub, lossis cov ntaub qhwv thermal.
Ib qho LED khiav ntawm 25 degree, piv txwv li, yuav kav 50,000 teev, tab sis ntawm 75 degree, nws lub neej yuav raug txiav ib nrab. Finned aluminium heat sinks txhim kho cov cua sov dissipation, tab sis tsis zoo ventilated fixtures khaws cua sov thiab deteriorate sai.
Ib puag ncig ntawm kev ua haujlwm
Lifespan yog cuam tshuam ncaj qha los ntawm ib puag ncig yam. Thaum cov av noo los yog corrosive ib puag ncig (xws li cov chaw ntug dej hiav txwv) tuaj yeem ua rau cov khoom siv sab hauv, qhov kub thiab txias (xws li cov pom hauv cov chaw tsim khoom) ua rau muaj kev ntxhov siab rau cov cua txias. Thaum tshav kub kub yog insulated thiab lub teeb tso zis yog thaiv los ntawm plua plav sau.
Xaiv cov khoom siv nrog cov kev ntsuam xyuas IP kom zoo: IP20 rau kev siv sab hauv tsev qhuav, thiab IP65 rau qhov chaw ntub dej. Cov khoom siv hluav taws xob tsis zoo raug tiv thaiv nyob rau hauv ib puag ncig hnyav los ntawm cov vaj tse kaw thiab tiv thaiv- cov coatings.
Cov qauv ntawm kev siv
Lub neej ua haujlwm raug cuam tshuam los ntawm kev ua haujlwm ntev lossis hloov pauv ntau zaus. Hauv 24/7 daim ntawv thov, LEDs nrog 50,000-teev kev ntsuam xyuas tsuas yog kav 5-7 xyoo thaum siv 8 teev ib hnub. Solder sib koom ua ke qaug zog yog coj los ntawm thermal cycling, uas yog rov ua cua sov thiab txias thaum lub sij hawm qhib / tawm. Lwm qhov tseem ceeb yog dimming: siv cov dimmers tsis sib xws ua rau muaj kev ntxhov siab hauv hluav taws xob, thaum ua haujlwm LEDs ntawm 50% ci ntsa iab txo qis cua sov thiab ua rau lub neej ntev.
Kev txhim kho zoo
Ib tug tsis zoo nruab system degrades kev ua tau zoo. Cov pa cua tsis zoo hauv qab nthab khaws cov cua sov, thiab cov xaim tsis ruaj ntseg tuaj yeem ua rau muaj hluav taws xob poob lossis arcing. Saib xyuas qhov siab mounting thiab qhov sib nrug cov lus pom zoo los ntawm cov chaw tsim khoom. Cua yuav tsum muaj peev xwm mus ncig ib ncig ntawm lub vaj huam sib luag hauv kev ncua kev teeb tsa.
Kev ruaj ntseg ntawm Kev Siv Hluav Taws Xob
Cov tsav tsheb thiab LEDs raug mob los ntawm qhov hluav taws xob nce thiab kev hloov pauv. Voltage stabilizers los yog surge protectors yog ib qho tseem ceeb nyob rau hauv cov cheeb tsam nrog erratic grids. Piv txwv li, cov khoom siv tsav tsheb tuaj yeem raug kib tam sim ntawd los ntawm 220V surge hauv 110V system.
Cov txheej txheem kho mob
Cov plua plav txuam rau ntawm cov dab dej kub thiab LEDs yog zam nrog kev tu txhua hnub. Txhua xyoo, xyuas cov kev sib txuas rau xoob lossis corrosion. Txhawm rau tiv thaiv qhov ua tsis tiav, hloov cov tsav tsheb tsis zoo sai li sai tau.
Kev tsim khoom zoo
Kev ua tsis tiav thaum ntxov yog tshwm sim los ntawm kev tswj tsis tau zoo, cov khoom siv tsis zoo, lossis cov khoom siv tsis zoo. Xaiv cov hom lag luam uas muaj ISO daim ntawv pov thawj thiab lav txij li lawv pom lawv txoj kev ntseeg nyob rau hauv lub neej ntev ntawm lawv cov khoom.
Tsim cov Fixtures
Kev tswj qhov kub thiab txias, ntev - cov ntaub ntawv siv tau ntev (xws li aluminium alloy), thiab kev tiv thaiv ib puag ncig yog tag nrho ua ke rau hauv qhov dej zoo- tsim kho. Txawm hais tias nyias profiles tuaj yeem cuam tshuam qhov kev ua haujlwm txias, cov qauv tsim qauv ua rau kev hloov pauv yooj yim dua.
LED vaj huam sib luag lub teeb lub neej ntev nyob ntawm seb tus neeg siv tus cwj pwm zoo npaum li cas, qhov chaw nyob ib puag ncig, thiab cov khoom zoo sib npaug. LED kev nqis peev tuaj yeem ua tiav los ntawm cov neeg siv khoom los ntawm kev xaiv cov khoom zoo -, xyuas kom tseeb tias lawv tau teeb tsa kom raug, thiab ua kom cov haujlwm ruaj khov. Ua raws li cov lus qhia no yuav lav qhov ntawdLED vaj huam sib luagtxuas ntxiv mus ua qhov pheej yig, ib puag ncig tus phooj ywg teeb pom kev zoo rau ntau xyoo tom ntej, txawm tias technology tsim.
