Yuav ua li cas xaiv LED raj?
Muaj ntau ntau lub tuam txhab LED fluorescent teeb, thiab cov khoom lag luam zoo thiab kev ua tau zoo sib txawv heev, yog li cov neeg tsis yog cov kws tshaj lij xws li cov tuam txhab lag luam txawv teb chaws, cov tuam txhab txuag hluav taws xob, cov tuam txhab engineering, thiab cov tuam txhab nyiaj txawv teb chaws cov chaw yuav khoom hauv Suav teb tsis paub yuav ua li cas. paub qhov txawv ntawm cov khoom tsim los ntawm txhua lub tuam txhab hauv cov txheej txheem ntawm kev yuav khoom. Qhov zoo thiab kev ua haujlwm ntawm LED fluorescent teeb tsis paub thaum yuav khoom. Kev yuav LED fluorescent teeb tuaj yeem yuav los ntawm cov hauv qab no: profiles, cov khoom siv fais fab, chips
1. Profile thiab qauv
Muaj ob hom profiles: tag nrho-yas thiab ib nrab-yas thiab ib nrab-aluminium kav.
1. All-yas raj: Lub teeb thaum ntxov LED fluorescent siv tag nrho-yas raj, vim nws tsuas yog siv cov khoom siv hluav taws xob tsis sib cais, txhawm rau kom tsis txhob muaj teeb meem ntawm hluav taws xob poob siab, nws yog qhov xav tau siv tag nrho-yas raj. Qhov teeb meem loj tshaj plaws ntawm lub teeb fluorescent zoo li no yog qhov teeb meem thaum tshav kub kub dissipation. Lub teeb lwj yog qhov hnyav heev. Lub kaus mom straw muaj lub neej luv luv, thiab nws tawg tsawg dua 2000 teev.
2. Semi-yas thiab ib nrab txhuas raj: LED fluorescent teeb muag hauv khw yog ib nrab ntawm PC thiab ib nrab txhuas txhuas. Yas yog siv rau ib nrab uas xav tau lub teeb kis tau tus mob, thiab ib nrab uas tsis xav tau lub teeb kis tau tus mob tab sis xav tau cua sov dissipation. Aluminium alloy. Cov khoom siv hluav taws xob tau muab tso rau hauv aluminium raj, kom cov cua sov tsim los ntawm LED ntxiv rau cov cua sov uas tsim los ntawm lub zog hluav taws xob yog qhov loj heev, vim tias lub zog ntawm lub teeb zoo li no feem ntau yog 20W. Yog tias lub zog loj dua, ib nrab ntawm lub raj txhuas txhuas yuav tsis daws nws qhov teeb meem kub dissipation.
2. Fais fab mov (qhov teeb meem tseem ceeb)
Lub hwj chim ntawm LED fluorescent teeb yog muab faib ua ob hom built-in hom thiab sab nraud hom. Built-in txhais tau hais tias cov khoom siv hluav taws xob tuaj yeem muab tso rau hauv lub raj. Qhov zoo tshaj plaws ntawm hom built-in no yog tias nws tuaj yeem hloov ncaj qha rau lub raj fluorescent uas twb muaj lawm yam tsis muaj kev hloov pauv hauv Circuit Court. Yog li ntawd, cov duab built-in yog tsim rau hauv ib txoj hlua ntev kom haum rau hauv lub teeb lub teeb semi-circular.
1. Cov khoom siv hluav taws xob tsis tu ncua tsis tu ncua: Tsis yog cais tawm txhais tau hais tias muaj kev sib txuas ncaj qha ntawm qhov kawg ntawm cov khoom siv thiab cov khoom siv kawg, yog li muaj kev pheej hmoo ntawm hluav taws xob poob siab yog tias lub load raug kov. Qhov kom zoo dua ntawm cov khoom siv tsis tu ncua tam sim no yog qhov kev tsim hluav taws xob yog qhov yooj yim thiab cov nqi tsim khoom tsis siab. Qhov tsis zoo yog tias qhov hluav taws xob siab ntawm AC fais fab mov yuav nkag mus rau qhov kawg ntawm kev thauj khoom, ua rau muaj kev pheej hmoo ntawm hluav taws xob poob siab.
2. Cov khoom siv hluav taws xob tsis tu ncua tam sim no: Cov khoom sib cais yog hais txog kev sib cais transformer ntawm qhov kev tawm tswv yim kawg thiab cov zis kawg. Tab sis nws tuaj yeem cais cov tswv yim thiab tawm. Qhov kom zoo dua ntawm kev sib cais qhov tam sim no qhov chaw yog qhov kev tsim Circuit Court yog qhov nyuaj. Qhov tsis zoo yog qhov ua tau zoo ntawm cov khoom siv hluav taws xob yuav raug txo, tus nqi tsim khoom yog siab, thiab qhov ntim kuj loj. Nws yog OK muab lub raj T10, tab sis lub raj T8 yog nruj dua.
3. Cov khoom siv hluav taws xob sab nraud: Txhawm rau kom tau txais kev ua tau zoo tshaj plaws, nws yog qhov zoo tshaj plaws los siv cov khoom siv hluav taws xob sab nraud. Tam sim no, cov chaw tseem ceeb los txhawb LED fluorescent teeb yog tsoomfwv cov chaw haujlwm, chaw ua haujlwm, khw muag khoom, tsev kawm ntawv, chaw nres tsheb hauv av, subways thiab lwm qhov chaw. Feem ntau ib chav siv ntau tshaj ib lub teeb fluorescent, tejzaum nws muaj ntau tshaj 10. Lub sijhawm no, yuav tsum tau siv lub hauv nruab nrab ntawm lub zog sab nraud. Lub zog hluav taws xob AC / DC hloov pauv hluav taws xob yog siv rau kev sib koom ua ke, thiab txhua lub teeb fluorescent siv DC / DC tsis tu ncua tam sim no module. Nyob rau hauv txoj kev no, qhov ua tau zoo tshaj plaws thiab lub zog loj tshaj plaws tuaj yeem tau txais. Qhov zoo ntawm centralized fais fab mov yog pom tseeb. Ntxiv mus, nws kuj yog ib qho kev sib cais fais fab mov, cov qauv no kuj yooj yim heev rau kev siv ntau yam dimming schemes,
Thib peb, lub chip
Raws li cov xwm txheej ib txwm muaj, feem ntau yog thawj kab hom xws li CREE, Osram, Hewlett-Packard (HP), Nichia, Toyoda Gosei Lumileds, thiab lwm yam. Cov npe thib ob suav nrog Epistar (Epistar) abbreviation: ES, (Lianquan, Yuankun. , Lian Yong, Guolian), Guanggal Optoelectronics (Huga), New Century (Genesis Photonics), Huashang (Arima Optoelectronics) abbreviation: AOC, Tekcore, Kellett, Juxin, Guanghong, Jingfa, Vision, Zhoulei, Liansheng (HPO), HL), Optical Lei (ED), Tyntek (Tyntek) Abbreviation: TK, Yao Fu Zhou Technology TC, Formosa Epitaxy (Formosa Epitaxy), Guotong, Lianding, Tshiab Optoelectronics (VPEC) thiab hais txog. Tam sim no siv nyob rau hauv fluorescent teeb yog specifications xws li 3528, 3020, 3014, thiab lwm yam. Cov specifications no mas yog vim lawv txawv qhov ntau thiab tsawg thiab cua kub dissipation txoj kev ntawm cov chips. Chips ntawm tib hom yog ntim los ntawm cov tuam txhab sib txawv thiab lawv qhov zoo kuj txawv.
Plaub, lwm yam
1. Tsau kawg: Tam sim no, muaj ntau txoj hauv kev ntawm cov pob qij txha, nrog rau cov tawv nqaij txhuas, cov khoom siv PC, thiab cov tawv nqaij aluminium ntxiv rau cov khoom siv PC. Raws li txoj kev kho, muaj cov kua nplaum ruaj khov ntawm ob qho kawg ntawm lub teeb raj, thiab cov ntsia hlau tuaj yeem siv los kho ob lub raj ntawm lub teeb raj. Txoj kev kho nrog screws yog saws los ntawm feem ntau ntawm cov neeg siv khoom.
2. Lub teeb xa hluav taws xob ntawm lub npog ntsej muag PC: lub teeb xa hluav taws xob ntawm lub ntsej muag pob tshab tuaj yeem ncav cuag 94-98%, thiab lub teeb xa hluav taws xob ntawm lub npog ntsej muag yog 80-86%. Yog hais tias lub luminous flux ntawm lub teeb raj tsis muaj lub npog ntsej muag yog 2000lm, ntxiv rau lub ntsej muag pob tshab nrog lub teeb xa hluav taws xob tsuas yog 88%, nws qhov tseeb luminous flux tsuas yog 1760lm.
Yog tias koj ntxiv lub ntsej muag pob tshab nrog lub teeb xa hluav taws xob ntawm 95% rau nws, ces nws qhov tseeb luminous flux yog 1900lm, uas kuj yog lub ntsej muag pob tshab. Vim li cas thiaj muaj qhov sib txawv loj ntawm ob? Cov lus teb yog nyob rau hauv cov khoom ntawm lub npog ntsej muag. Cov ntaub ntawv ntawm PC lub qhov ncauj qhov ntswg ntawm kev ua lag luam suav nrog cov khoom siv PC zoo tib yam thiab cov ntaub ntawv kho qhov muag PC. Vim hais tias ntawm cov manufacturers sib txawv, qhov sib txawv ntawm lub teeb transmittance yog heev loj.
4. Substrate: Mount LED nti nto ntawm PCB lossis txhuas substrate, thiab tom qab ntawd kho nws ntawm aluminium alloy radiator. Lub thermal conductivity ntawm iav fiber ntau PCB yog 20w / mk, thiab thermal conductivity ntawm aluminium alloy yog 200w / mk. Nws yog qhov zoo dua los siv aluminium substrate.
5. Lifespan: Lub neej ntev ntawm lub teeb feem ntau yog nyob ntawm kev sib xyaw ua ke ntawm cov chips, cov khoom siv hluav taws xob, cov cua sov dissipation thiab lwm yam. Hauv kev txheeb xyuas zaum kawg, tsuas yog cov ntaub ntawv yooj yim tshaj plaws.
6. Lub teeb nyhuv, lub teeb pom kev zoo dua, rau qee qhov, lub teeb no ua tau zoo dua! Chav tsev yog LM / W. Benwei' s luminous efficiency yog ntau tshaj 160LM, ua rau kev lag luam
7. Kev txiav txim siab ntawm cov cua sov dissipation: Ob peb feeb tom qab lub raj LED tau teeb, lub raj lub cev yuav tsum ua kom sov los ua pov thawj tias nws yog aluminium substrate kom dissipate cua sov. Ntawm qhov tsis sib xws, nws yog iav fiber board kom dissipate tshav kub.
