Dab tsi yog qhov LED:
LED yog lub npe ntawm lus Askiv teeb emitting diode. Nws cov qauv yooj yim yog ib qho khoom hluav taws xob hauv cov khoom hluav taws xob uas muab tso rau hauv ib lub txee hau, ces khi nrog cov tshuaj epoxy thiab siv cov khoom tsim nyog. Yuav ci tau txhua zaus.
LED teeb ci nta:
1. Voltage: LED siv cov hluav taws xob tsawg zog, lub hwj huam fais fab tuag yog nruab nrab ntawm 1.8-3.6V, nyob ntawm qhov khoom, yog li nws yog ib qho chaw muaj kev ruaj ntseg tshaj qhov siv hluav taws xob muaj hluav taws xob, tshwj xeeb tshaj yog tsim rau pej xeem cov chaw.
2. Kev Ua Tau: 80% tsawg zog noj dua li cov roj teeb uas muaj lub zog zoo tib yam
3. Kev Ruaj Ntseg: Nyob hauv txoj kev xav, nws tuaj yeem pom tau 100,000 xuab moos.
4. Lub teeb lwj: Nrog kev nce qib ntawm kev siv tshuab, lub teeb lwj tau me me thiab me dua. Ntais, lub teeb lauj ntawm lub teeb pom kev zoo ntawm lub teeb nyob rau hauv ib txhiab lub sij hawm tuaj yeem tswj tau li ntawm 5%, thiab tom qab ntau tshaj li ib txhiab teev, lub teeb lwj me me.
5. Kev tiv thaiv ib puag ncig: tsis muaj hluav taws xob, tsis muaj kev ua qias neeg, khoom pov thawj zoo tiag tiag. LED khoom yog feem ntau raug zam los ntawm kev kuaj xyuas thaum luam tawm
LED nti loj heev txiav txim siab:
Raws li cov qauv kev hloov, cov chips feem ntau muab faib ua cov wafers thiab cov sib tsoo. Ntawm lawv, cov wafer yog ib qib qis, thiab kev ua haujlwm tsis ruaj khov txaus. Peb lub tuam txhab feem ntau tsis siv LEDs ua los ntawm wafers; squares feem ntau ntsuas los ntawm qhov loj, xws li 12 mil (1 mais = 0.0254 mm 2). Nyob rau hauv dav dav, tib hom ntawm daim tawv nyias, qhov loj dua tus nti loj, lub siab dua lub ci ci. Cov khoom siv feem ntau siv LED teeb, xim liab thiab daj yog feem ntau 9 ~ 12mil, dawb, xiav thiab ntsuab yog feem ntau yog 12 ~ 14mil, uas yog qhov tseem ceeb tshaj plaws nti ntawm lub khw. Yog hais tias koj siv ib tug loj nti, Txawm hais tias lub brightness tau zoo dua ib tug ntau, tab sis tus nqi ntawm lub nti zoo heev nce, uas yog vim li cas lub loj loj nti yog tsis tshua muaj siv.
LED xim zoo nkauj:
Qhov sib txawv xim ntawm LEDs yog txiav txim siab los ntawm tej daim ntawm ntau lub wavelengths. Piv txwv li, lub teeb liab liab feem ntau muaj ib lub qhov ntev ntawm 620 ~ 630nm (nanometer), lub teeb ntsuab ci feem ntau muaj lub siab ntev ntawm 527nm, thiab xiav lub teeb chips muaj ib qho dav dav dav ntawm 470nm. Lub wavelength yog 585nm, thiab LED dawb kuj yog ib lub xiav nti, tab sis lub teeb dawb yog absitted los ntawm kev ntxiv ib qho tsim nyog ntawm phosphor mus rau lub xiav nti.
