Cov vaj huam sib luag ntawm lub teeb ci (LED vaj huam sib luag) teeb lub teeb pom kev thov lub neej ntawm" pom lub teeb tab sis tsis pom" ;. Nws muaj qhov zoo ntawm cov teeb pom kev zoo ntawm cov teeb pom kev zoo, muag muag thiab ntsiag to, huv thiab kaj, thiab muaj qhov zoo ntawm kev tiv thaiv yoov tshaj tawm, tiv thaiv pa taws, tiv thaiv huab thiab yooj yim los ntxuav; nws cov qauv yooj yim yog yooj yim rau kev sib xyaw nrog lub nthab qauv, yog li nws yog qhov tshwj xeeb tshaj yog muaj kev sib xyaw hauv qab nthab, thiab ib puag ncig muaj teeb meem ntau dua. Chav dej chav dej me me thiab chav ua noj muaj qhov kev thov zoo. Nyob rau tib lub sijhawm, LED teeb vaj huam sib luag tseem muaj ntau yam ntxwv xws li kev siv hluav taws xob tsawg, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, lub neej ntev, kev siv yig; thev naus laus zis zam, daim ntawv thov yooj yim, thiab lwm yam, uas yog lub siab hlub los ntawm cov neeg siv khoom niaj hnub.
Txawm li cas los xij, nrog kev nthuav dav sai ntawm kev lag luam ua qab nthab kev lag luam thiab cov neeg nyiam ntawm cov ntawv thov LED, vim tias tsis muaj ib qho qauv ua raws li kev teeb tsa LED vaj huam sib luag thiab tsis muaj kev tswj hwm ntawm tsoomfwv kev tswj hwm, ntau tus neeg ua haujlwm cov nyom. Hauv kev ua lag luam, muaj ntau ntawm cov vaj huam sib luag ntawm LED teeb nrog lub neej luv, lub teeb tsis zoo thiab cov luminous efficiency, thiab txawm tias xau xwm txheej. Muaj cov kev yws tsis tu ncua los ntawm cov neeg siv thiab cov tswv lag luam tsis muaj kev pab cuam tom qab muag. Qhov no cuam tshuam loj heev rau kev lag luam kev txiav txim siab thiab kev ntseeg siab ntawm LED vaj huam sib luag teeb thiab cuam tshuam kev lag luam. Kev noj qab haus huv zoo. Ntawm no, cia peb dissect LED vaj huam sib luag lag luam teeb pom kev lag luam los ntawm cov txheej txheem kev pom, tshwj xeeb tshaj yog cov lag luam LED vaj huam sib luag lub lag luam teeb pom kev lag luam hauv kev sib xyaw ua ke qab nthab.
LED teeb hluav taws xob cov khoom siv tam sim no siv hauv LED teeb vaj huam sib luag
Vim tias nws qhov loj me me, tsim nyog lub zog, siab luminous efficiency, yooj yim lub teeb tswj hluav taws xob thiab cov cua sov tawm, qhov hluav taws xob LED teeb tam sim no los ntawm qhov ntxov tshaj plaws 3528 mus rau tom qab 3014, 2835, rau qhov tam sim no siv SMD4014 teeb lub teeb.
Cov xwm txheej ntawm cov tub ntxhais feem sib zog tsav fais fab
Vim tias LED teeb hlaws roj teeb ua rau hluav taws xob tsawg pib ua hluav taws xob cov khoom siv hluav taws xob, qhov yuav tsum tau ua kom yooj yim tshaj plaws yog qhov lawv yuav tsum tau tsav los ntawm cov hluav taws xob sib txig hluav taws xob tsawg thiab xav tau kev txuas tas li tas li tam sim no. Yog tias qhov tam sim no kub dhau lawm, lub teeb kom sai sai, thiab lub teeb yuav qaim heev lossis txawm hlawv tawm tom qab lub sijhawm ntev.
Ntawm nimno, muaj mas peb kev hais daws rau tsav tsheb LED zog:
1. Lub zog-lub zog ua haujlwm-theem: qhov kev daws teeb meem yooj yim, ob peb lub Cheebtsam, tsis tshua muaj nqi, tsis siv hluav taws xob tas li. Nws yog tsuas yog siv rau LED teeb teeb tsa ntawm 3W thiab qis dua, thiab muaj kev pheej hmoo ntawm kev xau los ntawm lub rooj tsav xwm teeb, yog li cov txheej txheem plhaub ntawm lub teeb lub cev yuav tsum muaj rwb thaiv tsev;
2. Lub tshuab hluav taws xob tsis zoo: cov nqi nruab nrab, siv cov hluav taws xob IC tas li tam sim no, tab sis kuj tseem muaj kev pheej hmoo ntawm kev xau tuaj vim los ntawm kev tawg, thiab lub plhaub teeb ntawm lub teeb lub cev yuav tsum tau rwb thaiv tsev.
3. Kev rho tawm hluav taws xob sib txawv: tus nqi siab, IC tsis tu ncua tam sim no, kev nyab xeeb zoo.
Txhawm rau kom ua tiav lub teeb pom kev zoo dua, LED teeb vaj huam sib luag feem ntau muaj cov qauv sib luag. Xws li, txhawm rau kom paub tseeb tias cov cua sov dissipation ntawm LED teeb, txhua tus qauv txhuas tam sim no tau siv los ua kab noj hniav kom tsis txhob muaj cua sov. Qhov tsis yog qhov teeb meem ntawm txhuas lub teeb lub cev yuav tsum siv lub hwj huam hluav taws xob kom muaj kev tiv thaiv kev nyab xeeb, thiab tib lub sijhawm, nws tuaj yeem muab qhov teeb meem txuas mus tas li kom ntseeg tau lub neej ntev ntawm cov teeb hlaws.
