Dab tsi' s Qhov sib txawv ntawm SMD thiab COB LED teeb
Qhov kev tsim hluav taws xob yooj yim no yog qhov laj thawj rau lub vaj huam sib luag zoo li muaj COB LED teeb nyob qhov twg, ntawm lub teeb SMD, zoo li ib pawg ntawm cov teeb me dua. 2) Txawm li cas los xij, COB LED teeb tsis tuaj yeem siv los tsim qhov muag teeb lossis teeb pom kev vim tias tsuas muaj ob qhov kev sib cuag thiab 1 Circuit.
Qhov twg los xaiv: SMD vs. COB LED Teeb
Peb txhua tus xav tau lub teeb uas tuaj yeem coj peb hla qhov tsaus ntuj thiab qhia peb kom raug. Tias yog vim li cas xaiv lub teeb pom kev zoo LED yog qhov tseem ceeb heev. Txawm li cas los xij, ntau yam qauv ntawm LED teeb tau nrov heev dua li cov teeb pom kev ib txwm muaj vim tias cov teeb ci LED tuaj yeem nyob ntev li 25 zaug ntev dua nrog kev siv hluav taws xob tsawg.
Dab tsi yog COB LED thiab dab tsi yog SMD LED thiab ntawm chav kawm uas yog qhov zoo rau koj. Txhua tus qauv tsim muaj nws cov txiaj ntsig, thiab tam sim no kuv yuav taug kev koj vim li cas tib neeg thiaj xaiv ib qho piv rau lwm qhov rau lawv daim ntawv thov tshwj xeeb.
SMD yog dab tsi?
SMD hais txog lub sij hawm "Surface Mounted Device" LEDs, uas yog qhov sib koom ua ke tshaj plaws LEDs hauv khw. LED nti tau nyob mus ib txhis rau cov ntawv luam tawm Circuit Board (PCB), thiab nws yog qhov tshwj xeeb tshaj yog vim nws muaj ntau yam. PCB tau tsim los ntawm cov duab plaub fab, cov khoom tiaj tus, uas yog qhov peb ib txwm pom zoo li SMD. Yog tias koj saib mus rau hauv SMD LED ze, koj tuaj yeem pom qhov me me dub txoj cai nyob hauv nruab nrab ntawm SMD; uas yog LED nti. Koj tuaj yeem pom nws hauv cov teeb pom kev zoo thiab cov teeb pom kev zoo thiab txawm tias nyob hauv lub teeb ceeb toom ntawm koj lub xov tooj ntawm tes.
Muaj ntau qhov ntau thiab tsawg ntawm SMD LED chips: 2835, 3030, 3014, 5050, 5630; lawv tau hais raws li lawv qhov ntev: ntev thiab dav. Piv txwv li, qhov loj ntawm 2835 yog 2.8 x 3.5mm, 3030 yog 3.0 x 3.0mm, 3014 yog 3.5 x 2.8mm, 5050 yog 5.0 x 5.0mm, thiab 5630 yog 5.6 x 3.0mm. Cov SMD chips me me thiab ze rau qhov tsim ntawm lub tiaj, square computer chip.
SMD chips tau ua lub luag haujlwm tseem ceeb hauv kev nce qib rau LED kev lag luam vim tias muaj peev xwm tso peb diodes rau tib lub nti. Thaum lub nti muaj xim liab, ntsuab, thiab xiav diode, nws tuaj yeem tsim cov xim uas koj xav tau los ntawm kev kho qib tso zis los ntawm txhua lub diode ntawm lub nti. Raws li lawv ci heev thiab tuaj yeem hloov xim, nws tuaj yeem siv dav rau LED sawb teeb thiab teeb pom kev zoo.
Cov nti tau tiv thaiv nrog phosphor hmoov thiab zoo li daj lossis txiv kab ntxwv. Qhov daj feem ntau tso tawm nruab hnub nrig dawb (6000-6500K), thiab txiv kab ntxwv feem ntau tso tawm lub teeb sov sov (2700-3500K).
COB yog dab tsi?
Ib qhov kev txhim kho tshiab kawg hauv kev lag luam LED yog COB lossis "Chip on Board" thev naus laus zis uas yog ib qib zuj zus rau kev siv hluav taws xob ntau dua. Zoo ib yam li SMD, COB chips ib yam muaj ntau lub diodes ntawm tib qhov chaw. Tab sis qhov sib txawv ntawm LED teeb COB thiab SMD yog tias COB LEDs muaj diodes ntau dua.
Txuas mus rau 3528: 1 nti ntawm lub rooj tsavxwm, lossis 5050: 3 chips, COB LED lub teeb ci tuaj yeem muaj ntau daim npav (kaum ob lossis ntau pua) nyob rau tib daim Luam Luam Circuit Board (PCB).
COB muaj lub rooj tsav xwm luam tawm ntawm nws lub hauv paus; diode chips tau teeb tsa ua ke lossis/thiab ua ntu zus, raws li Circuit Court ntawm PCB. Lub substrate tuaj yeem yog aluminium lossis ceramic. Hom ceramic muaj kev txhim kho kev ua kom muaj cua sov zoo uas tuaj yeem lav qhov qis dua LED ua haujlwm kub. Txawm hais tias COB LED sib xyaw ntau cov chips rau hauv ib txheej, nws tsuas muaj ob lub hlau sib koom ua ke: anode thiab cathode.
Raws li COB nce cov chips ncaj qha mus rau txheej txheej, uas muaj thaj chaw txias txias, COB muaj cov cua sov zoo dua piv rau SMD. Raws li qhov tshwm sim, thaum peb tsim lub voj voog ntawm lub substrate, peb yuav txiav txim siab ua kom luv cov chips kom tau txais COB qhov loj me me li sai tau.
Qhov sib txawv ntawm SMD thiab COB LED teeb
SMD:
1) SMD LED chips tuaj yeem muaj txog li 3 diodes ntawm ib lub nti, nrog rau txhua lub diode muaj ib tus zuj zus. Txhua lub Circuit Court muaj ib qho cathode thiab ib qho anode, ua rau 2, 4 lossis 6 tus neeg nyob hauv ib lub nti.
2) Qhov kev sib dhos no yog qhov laj thawj vim li cas SMD chips muaj ntau yam sib piv piv rau COB. Cov nti tuaj yeem muaj xim liab, ntsuab, thiab xiav diode. Los ntawm kev siv peb lub diodes, koj tuaj yeem tsim cov xim yooj yim los ntawm kev kho qib tso zis.
3) SMD chips paub txog lawv qhov ci, thiab nws tuaj yeem tsim 50 txog 100 lumens ib watt.
COB:
1) COB chips ib txwm muaj 9 lossis ntau dua diodes. Ntxiv mus, COB chips tseem muaj 1 Circuit thiab muaj ob tus neeg sib tham, tsis hais tus naj npawb ntawm diodes. Qhov kev tsim hluav taws xob yooj yim no yog qhov laj thawj rau lub vaj huam sib luag zoo li muaj COB LED teeb nyob qhov twg, ntawm lub teeb SMD, zoo li ib pawg ntawm cov teeb me dua.
2) Txawm li cas los xij, COB LED teeb tsis tuaj yeem siv los tsim qhov muag teeb lossis teeb pom kev vim tias tsuas muaj ob qhov kev sib cuag thiab 1 Circuit. Kev hloov kho ntau txoj hauv kev yog xav tau los tsim cov xim hloov pauv. Yog li no, COB LED teeb tau zoo nyob rau hauv ib daim ntawv thov xim tab sis tsis yog siv thev naus laus zis ntau yam.
3) COB paub txog lumen zoo dua watt piv thiab ua kom sov. COB chips tuaj yeem tsim ntau dua lumens nrog lub zog tsawg nrog qhov tsawg kawg ntawm 80 lumens ib watt. Koj tuaj yeem pom nws hauv txhua hom qij thiab daim ntawv thov, zoo li nyem ntawm koj lub xov tooj ntawm tes lossis lub koob yees duab taw tes thiab tua.
Vim li cas qhov kev tsim vaj tsev tsim qhov me me COB LED?
Hauv SMD theem, xav txog qhov koj xav tsim kom muaj 50 watt sab nraum zoov LED dej nyab teeb, thaum 3528 tsuas muaj 0.06 watt. Qhov ntawd txhais tau tias koj yuav xav tau txog (50/0.06=833) 833 daim 3528 SMD ntawm lub teeb pom kev tag nrho, thiab txawm tias txhua 3528 SMD kuj tseem xav tau chaw tso cua thiab tso cua sov tawm.
Txawm li cas los xij, ib txwm LED dej nyab teeb yuav tsis muaj chaw txaus rau 833 daim ntawm 3528 SMD. Nws ua tsis tau.
Tab sis nyob rau qhov xwm txheej no, COB LED los ua ke, thiab 50w COB LED qhov ntev tsuas yog 36 x 36mm. Li no, 36 x 36mm yuav daws qhov teeb meem, nrog 833 daim ntawm 3.5 x 2.8mm uas zoo heev.
