Yog tias koj tab tom nkag mus rau hauv DIY teeb pom kev zoo - tsim lub rooj teeb, lub teeb cog cog, teeb pom kev hauv tsev, lossis lwm yam muaj tswv yim ntxiv - ib qho ntawm thawj qhov kev txiav txim siab tiag tiag koj yuav ntsib yog seb puas yuav mus nrog DC COB lossis AC COB LED modules. Ob leeg muab rau koj uas du, txawm illumination COBs yog hlub rau, tab sis txoj kev lawv lis hwj chim hloov txhua yam ntawm koj tsim.
Phau ntawv qhia no taug kev los ntawm cov tswv yim sib txawv raws li qhov tseem ceeb rau cov neeg nyiam nyiam. Peb mam li npog cov ntsiab lus tseem ceeb los xyuas, qhov muaj zog thiab qhov tsis muaj zog ntawm txhua qhov, kev siv ib txwm, thiab tus nqi tiag tiag. Lub hom phiaj yog los pab koj kom tsis txhob mob taub hau thiab xaiv qhov zoo tshaj plaws haum rau koj qhov project.
Ceev Basics
DC COB LEDsua haujlwm ntawm qhov tam sim no ncaj qha, feem ntau ntawm qis voltages xws li 12V, 24V, lossis zoo sib xws. Lawv xav tau tus tsav tsheb sab nraud LED lossis lub zog hluav taws xob.
AC COB LEDs(tseem hu ua DOB - Tus Tsav Tsheb ntawm Lub Rooj Tswjhwm Saib) txuas ncaj qha rau cov qauv hauv tsev AC fais fab (110V lossis 220-240V). Tus tsav tsheb yog tsim rau hauv lub module nws tus kheej.
WELCOB tsim ob hom, nrog rau feem ntau siv flip nti ntim (tsis muaj kub hlau) tshwj tsis yog rau qee yam UV thiab IR wavelengths. Qhov kev tsim kho no feem ntau txhim kho cov cua sov thiab kev cia siab ntev ntev -.
Key Photoelectric Parameters thiab Indicators Saib
Tsom ntsoov rau cov no thaum sib piv cov qauv - lawv ua qhov sib txawv loj tshaj plaws hauv kev ua tau zoo ntawm - ntiaj teb no:
•Input voltage thiab tam sim no: DC modules teev qhov tseeb DC voltage thiab tam sim no kos. AC modules raug ntsuas rau lub zog hluav taws xob. Ua qhov no tsis ncaj ncees lawm, thiab koj yuav pom flickering, dim zis, lossis ua tsis tau sai.
• Lub zog (wattage): Muab nws rau koj lub heatsink thiab qhov project loj. Kev ua haujlwm tiag tiag wattage tseem ceeb tshaj li qhov tshaj tawm tshaj tawm.
• Luminous Efficiency (lm/W): Siab dua yog qhov zoo dua - nrhiav 100–140 lm/W lossis siab dua rau lub teeb pom kev zoo uas muaj cua sov tsawg.
• Xim kub (CCT) thiab CRI: 2700K-6500K ntau yam rau kev xav tau sib txawv. CRI 80+ (zoo dua 90+) ua kom cov xim ntuj, tshwj xeeb tshaj yog rau kev yees duab lossis cov nroj tsuag.
• Thermal Resistance thiab Heat Management: Txheeb xyuas qhov ntsuas kub ntawm qhov sib txuas thiab cov khoom siv substrate. Zoo flip chip designs khiav noticeably txias.
• Saib lub kaum sab xis thiab lub teeb: Feem ntau yog nyob ib ncig ntawm 120 degree. Ib cheeb tsam emitting loj yuav pab tau txawm tias teeb pom kev zoo hauv cov khoom siv.
Yog tias ua tau, sim ib qho qauv ua ntej cog lus rau kev tsim kom tiav.
Qhov zoo thiab qhov tsis zoo ntawm txhua hom
DC COB LEDs
Lub zog:
• Muaj kev nyab xeeb dua -voltage lag luam, uas xav tias pib dua- tus phooj ywg thiab zoo dua nyob ib puag ncig cov menyuam yaus, tsiaj txhu, lossis chaw ntub dej.
• Zoo heev rau dimming, ntse controllers, roj teeb, hnub ci teeb, los yog meej brightness hloov.
• Feem ntau me ntsis kev ua tau zoo tag nrho vim tsis muaj AC - mus rau - DC hloov dua siab tshiab ntawm LED board.
• Yooj yim rau kev koom ua ke nrog cov khoom siv hluav taws xob kev cai lossis 12V / 24V systems uas twb muaj lawm.
Qhov tsis zoo:
• Koj xav tau tus tsav tsheb sib cais LED lossis lub hwj chim, uas ntxiv lwm cov nqi ntawm cov khoom siv, txuas ntxiv, thiab qhov ua tsis tau zoo.
• Ntau txoj kev teeb tsa yog tias koj tsis xis nyob nrog xaiv thiab mounting tsav tsheb.
• Cov neeg tsav tsheb sab nraud tuaj yeem siv qhov chaw nyob hauv cov khoom siv nruj thiab yuav qhia txog lawv tus kheej cov teeb meem kub ntxhov lossis suab nrov.
AC COB LEDs
Lub zog:
• Kev xaim yooj yim heev - feem ntau tsuas yog txuas nyob, nruab nrab, thiab hauv av mus rau tus qauv hloov lossis qhov hluav taws xob.
• Tsawg dua qhov tag nrho, uas txhais tau hais tias tsawg dua los daws teeb meem thiab ua kom huv, tsim kom muaj zog dua.
• Yooj yim rau txhua tus uas xav tau ntsaws-thiab- ua si tau yam tsis muaj kev paub txog hluav taws xob ntxiv.
Qhov tsis zoo:
• Ua tau - nyob rau hauv tus neeg tsav tsheb tuaj yeem ua rau lub module khiav me ntsis sov dua, thiab kev ua haujlwm yuav qis dua me ntsis vim yog onboard AC hloov dua siab tshiab.
• Yooj yim dua rau dimming lossis ntse tswj tshwj tsis yog tus qauv tshwj xeeb txhawb nqa nws (qee yam ua, tab sis tsis yog tag nrho).
• Cov hluav taws xob siab dua txhais tau tias koj yuav tsum tau ceev faj ntxiv nrog rau kev ruaj ntseg thiab kev rwb thaiv tsev. Tsis zoo rau cov khoom siv txawb lossis roj teeb -powered tej yaam num.
• Voltage fluctuations ntawm mains fais fab tej zaum yuav cuam tshuam qhov sib xws ntau tshaj li ib tug zoo - tswj DC teeb.
Nyob rau hauv ob qho tib si, zoo flip nti tsim pab txo cov kev pheej hmoo xws li xaim daim ntawv cog lus tsis ua hauj lwm nyob rau lub sij hawm, uas yog ib tug zoo kev cia siab rau boost rau tej DIY project uas koj xav kom kav.
Qhov twg Txhua Hom Shines hauv DIY Projects
• DC COBua haujlwm zoo rau lub teeb txawb, tsheb lossis chaw pw hav zoov, cov tsev pheeb suab loj hlob, kev yees duab softboxes, drone teeb pom kev zoo mods, lossis ib qho kev tsim kho qhov twg koj xav tau kev tswj kom zoo lossis tawm ntawm - daim phiaj muaj peev xwm.
• AC COBFeem ntau yog qhov zoo dua rau cov khoom siv hauv tsev xws li teeb ci qab nthab, LED loj hlob teeb, rhiav overheads, lossis ib qhov project uas ua raws li cov qauv teeb hauv tsev.
Pib los ntawm kev saib koj lub zog hluav taws xob thiab seb lub teeb xav tau txav los yog koom nrog lwm yam khoom siv hluav taws xob.
Kev txiav txim siab nqi
Cov nqi them ua ntej:AC modules tuaj yeem saib pheej yig dua thaum xub thawj vim tias tus tsav tsheb twb suav nrog. DC teeb tsa feem ntau raug nqi me ntsis ntxiv thaum koj ua rau tus tsav tsheb sab nraud zoo.
Ntev -cov nqi them sijhawm:Kev ua tau zoo dua (siab dua lm / W) txuag nyiaj ntawm hluav taws xob. Kev ntseeg siab kuj tseem ceeb rau - modules los ntawm cov chaw tsim khoom nrog kev tswj xyuas nruj, kev kub hnyiab tag- hauv kev sim, thiab dhau kaum xyoo ntawm kev tsim khoom feem ntau yuav tsum tau hloov tsis tu ncua.
Yuav txiav txim siab li cas ntawm koj qhov project
1. Sau koj lub hwj chim qhov chaw thiab ib puag ncig kev teeb tsa.
2. Txiav txim siab npaum li cas tswj (dimming, ntse nta, portability) koj xav tau tiag tiag.
3. Qhov tseem ceeb ntawm qhov chaw muaj rau cov tsav tsheb thiab heatsinking.
4. Xav txog koj qib kev nplij siab nrog cov xaim thiab hluav taws xob.
5. Muab cov ntaub ntawv pov thawj thiab, qhov zoo tshaj plaws, cov qauv kuaj hauv qab cov xwm txheej tiag tiag - xyuas cov cua sov, lub teeb zoo, thiab kev ruaj ntseg tom qab khiav ob peb teev.
Ntau tus kws paub txog DIYers khaws ob hom ntawm tes thiab xaiv ib qhov project. Ib tus neeg muag khoom uas muaj kev hloov kho zoo (qhov sib txawv ntawm qhov sib txawv, xim, qib zog, thiab cov qauv nrawm) ua rau tag nrho cov txheej txheem smoother.
Tau txais DC vs AC xaiv txoj cai tshem tawm ib qho kev ntxhov siab loj dua hauv COB tsim. Thaum qhov ntawd tau txheeb xyuas, qhov seem ntawm qhov project - heatsinking, optics, thiab sib dhos - ua rau muaj kev lom zem ntau dua. Yog tias koj tab tom ua haujlwm ntawm ib txoj haujlwm tshwj xeeb, thov xa peb cov lus nug nrog qee cov ntsiab lus (xws li lub hom phiaj lub zog lossis daim ntawv thov scenarios); qhov no yuav tso cai rau peb muab cov lus pom zoo ntxiv.
