Txhawm rau pib, nws yog ib qho tsim nyog yuav tsum muaj lub hauv paus tuav ntawm Surface-Mounted Device (SMD) LEDs.Lawv yog unquestionably cov LEDs uas tau siv feem ntau tam sim no.Vim nws muaj ntau yam, txawm tias nyob rau hauv lub teeb ceeb toom ntawm lub xov tooj smartphone, LED nti yog nrees fused rau lub rooj tsavxwm luam tawm thiab tau ua haujlwm dav.Ib qho tshwj xeeb tshaj plaws ntawm SMD LED chips yog tus naj npawb ntawm kev sib txuas thiab diodes.
Ntawm SMD LED chips, nws muaj peev xwm muaj ntau tshaj ob qhov kev sib txuas.Txog li peb lub diodes nrog ib tus neeg circuits tuaj yeem pom ntawm ib nti.Txhua lub voj voog yuav muaj anode thiab cathode, uas 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 qhov hluav taws xob hauv ib nti ntawm hom no muaj ib lub cathode thiab ib qho anode, uas ua rau 2, 4, lossis 6 kev sib txuas.COB chips feem ntau muaj cuaj diodes lossis ntau dua.Tsis tas li ntawd, COB chips muaj ob qhov kev sib txuas thiab ib lub voj voog tsis hais txog qhov ntau ntawm diodes.Vim qhov kev tsim hluav taws xob yooj yim no, COB LED teeb muaj lub vaj huam sib luag zoo li, qhov SMD LED teeb yuav tshwm sim los ntawm cov teeb me me.
Ib qho liab, ntsuab, thiab xiav diode tuaj yeem muaj nyob ntawm SMD LED nti.Los ntawm kev hloov 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 yooj yim sua kom siv lawv los ua cov teeb hloov xim lossis cov qij.Ntau qhov kev hloov kho channel yuav tsum tau ua kom tau txais cov nyhuv hloov xim.Raws li qhov tshwm sim, COB LED teeb ua haujlwm zoo hauv cov ntawv thov uas xav tau ib qho xim, tab sis tsis yog ob peb xim.
SMD chips muaj qhov paub zoo ntawm qhov ci ci ntawm 50 txog 100 lumens ib watt.Qhov zoo tshaj plaws kub efficiency thiab lumens ib watt piv ntawm COB paub zoo.COB chips tuaj yeem tawm ntau lumens nrog hluav taws xob tsawg yog tias lawv muaj tsawg kawg yog 80 lumens ib watt.Nws tuaj yeem pom muaj ntau yam ntawm cov qij thiab cov khoom siv, xws li lub teeb nyem ntawm koj lub xov tooj lossis lub koob yees duab taw tes thiab tua.
Lub zog sab nraud me me yog xav tau rau SMD LED chips, thaum lub zog sab nraud loj dua yog xav tau rau COB LED chips.
