What "COB" txhais tau tias
COB (Chip On Board) yog ib qho kev ntim khoom siv thev naus laus zis uas muaj ntau lub teeb ci LED ncaj qha mus rau PCB thiab tom qab ntawd them nrog txheej txheej phosphor.
Piv nrog rau cov tsoos SMD LED strips, LED COB lub teeb strips xa cov dot -dawb, smoother, thiab ntau cov kab teeb pom kev zoo sib xws- zoo tagnrho rau niaj hnub architectural thiab kev lag luam daim ntawv thov.
COB LED Sawb ua haujlwm li cas
1. Ntau Micro LED Chips Mounted ncaj qha rau ntawm PCB
COB thev naus laus zis tso ntau pua micro LED chips ze rau ntawm tooj liab PCB.
Qhov kev ua haujlwm siab - ntom ntom no txhim kho:
Thaum tshav kub kub dissipation
Lub teeb uniformity
Kev ntseeg tau
Yooj yim
Ib lub 'meter' feem ntau suav nrog 320-640 chips, muab cov teeb pom kev huv, tsis tu ncua.
2. High-Cov Phosphor Txheej Zoo Siv los ntawm Chaw Tsim Tshuaj
Raws li tus kws tshaj lij LED COB lub teeb strips chaw tsim khoom, peb sib npaug siv cov qib siab - zoo phosphor txheej hla tag nrho cov array ntawm LED chips, kom ntseeg tau tias:
Kev hloov xim ruaj khov
Lub teeb pom kev zoo ib yam
du, dot-dawb illumination
Cov txheej txheem no zoo ib yam li qhov hwm LED qhov muag teev ua tiav lub teeb dawb.
3. Nruam, Uniform Linear Light Output
Vim hais tias cov chips yog heev ze thiab phosphor txheej ua raws li ib tug diffuser, lub sawb tsim:
Tsis pom hotspots
Tsis muaj LED dots, txawm nyob rau hauv ultra- nyias aluminium profiles
Mos, qhov muag - lub teeb zoo
Qhov no ua rau COB zoo tagnrho rau:
Linear teeb pom kev zoo
Zaub txee
Kho kom zoo nkauj sab hauv
Rooj tog teeb pom kev zoo
Chaw tos txais thiab khw muag khoom
4. Flexible PCB khoom siv hluav taws xob thiab ruaj khov kev ua haujlwm
Lub PCB hloov tau siv siab -purity tooj liab rau:
Muab lub zog ua haujlwm zoo hla ntawm cov nti arrays
Ua kom ruaj khov voltage
Txhawb nqa ntev - kev cia siab rau lub sijhawm
Qhov no ua kom qhov ci ntsa iab zoo ib yam ntawm tag nrho cov kab txaij.
5. Powered los ntawm Tsawg Voltage
COB strips yog tsim los nrog kev sib luag / series LED nti pawg.
Thaum powered los ntawm 24V DC, cov chips illumination sib npaug nrog:
Tsawg zog noj
High light efficiency
Txo cov cua sov tsim
