Ua ntej, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab yooj yim ntawm cov khoom siv saum npoo av (SMD) LEDs. Lawv yog undoubtedly cov feem ntau siv LEDs tam sim no. Vim lawv muaj ntau yam, LED chips tau ruaj khov rau cov ntawv luam tawm hauv Circuit Court boards thiab dav siv txawm nyob rau hauv smartphone ceeb toom teeb. Ib qho tseem ceeb tshaj plaws ntawm SMD LED chips yog tus naj npawb ntawm kev sib txuas thiab diodes.
Ntawm SMD LED nti, tuaj yeem muaj ntau tshaj li ob qhov kev sib txuas. Txog li peb lub diodes nrog kev ywj pheej circuits tuaj yeem pom ntawm ib nti. Txhua lub voj voog muaj anode thiab cathode, ua rau 2, 4, lossis 6 kev sib txuas ntawm lub nti.
Qhov sib txawv ntawm COB LEDs thiab SMD LEDs
Ntawm ib qho SMD LED nti, tuaj yeem muaj txog li peb lub diodes, txhua tus muaj nws tus kheej circuit. Txhua lub voj voog hauv cov nti no muaj cov cathode thiab anode, uas ua rau 2, 4, lossis 6 kev sib txuas. COB chips feem ntau muaj cuaj lossis ntau dua diodes. Tsis tas li ntawd, COB chips muaj ob qhov kev sib txuas thiab ib lub voj voog tsis hais tus naj npawb ntawm diodes. Vim qhov kev tsim hluav taws xob yooj yim no, COB LED teeb muaj lub vaj huam sib luag zoo li, thaum SMD LED teeb zoo li ib pawg ntawm cov teeb me me.
Liab, ntsuab, thiab xiav diodes tuaj yeem muaj nyob ntawm SMD LED nti. Los ntawm kev sib txawv ntawm cov zis theem ntawm peb lub diodes, koj tuaj yeem tsim cov xim. Ntawm COB LED teeb, txawm li cas los xij, tsuas muaj ob qhov kev sib cuag thiab ib lub voj voog. Nws tsis tuaj yeem ua lub teeb hloov xim lossis lub teeb nrog lawv. Kev hloov kho ntau lub channel yuav tsum tau ua kom tau txais cov nyhuv hloov xim. Yog li ntawd, COB LED teeb ua haujlwm zoo hauv cov ntawv thov uas xav tau ib qho xim es tsis muaj ntau xim.
Qhov ci ci ntawm SMD chips paub zoo tias yog 50 txog 100 lumens ib watt. COB paub zoo rau nws cov thermal efficiency thiab lumen ib watt piv. Yog tias COB nti muaj tsawg kawg yog 80 lumens ib watt, nws tuaj yeem tawm ntau lumens nrog hluav taws xob tsawg. Nws tuaj yeem siv tau ntau yam ntawm cov qij thiab cov khoom siv, xws li lub xov tooj ntawm tes flash lossis cov koob yees duab taw tes thiab tua.
Ntxiv rau qhov no, SMD LED chips xav tau lub zog sab nraud me me, thaum COB LED chips xav tau lub zog sab nraud loj dua.
