Vim li cas ED zaub tshuaj ntsuam tuaj yeem siv dav, kuv cov ntsiab lus yog raws li hauv qab no:
1. Cov kab kev cuam tshuam: qhov loj dua ntawm lub vijtsam LCD, qhov siab dua cov khoom siv nqis peev hauv kab ntau lawm. Qhov nce nyob rau hauv qhov loj me ntawm LED zaub yog yooj yim heev, ib yam li tsev txuas. Cov kev daws teeb meem nws tseem yooj yim kom paub raws li cov neeg siv kev xav tau.
2. Cov xim tag nrho: cov taws teeb, neon teeb, thiab lwm yam yog txhua qhov monochromatic, LED paub qhov tseeb ntawm kev sib xyaw RGB peb thawj xim.
3. Qhov kev ntseeg tau siab: LED yog lub teeb pom kev zoo-lub xeev nrog kev ntseeg siab, tsis zoo li cov leeg neon, cov qij thiab zoo li uas yuav tsum tau muaj cov hlab nqus.
4. Lub neej ntev: lub theoretical lub neej ntawm cov LED nti tuaj yeem ncav 100,000 teev, thiab lub neej ua haujlwm ntev dua 30,000 teev.
5. Kev tiv thaiv ib puag ncig: LED nws tus kheej yog lub zog-txuag thiab cov pa phem.
Qhov teeb meem loj tshaj plaws tam sim no tau ntsib los ntawm LEDs yog kub dissipation, thiab tib yam yog qhov tseeb rau cov duab LED. Lub zog siv ntawm cov LED zaub yog loj heev, thiab ib qho muaj nuj nqis ntawm lub zog tsis txaus siab rau lub cua sov. Kub taub hau tuaj yeem tsim cov teeb meem hauv qab no:
1. Wavelength drift: Wavelength drift yuav ua rau muaj teeb meem hauv kev kho cov xim. Lub nthwv dej nthwv dej ntawm lub LED yog qhov sib txawv ntawm qhov kub tsawg thiab siab kub. Raws li cov ntaub ntawv sim, rau txhua txhua qhov kev hloov ntawm qhov kub, qhov kev hloov pauv hloov yog 0.2-0.3nm.
2. Tawm cov teeb ci tawm tau txo qis: 1% ntawm cov zis hloov pauv hloov tshwm sim los ntawm qhov kub hloov pauv mus rau ib pawg Celsius, ntawm qhov hluav taws xob liab tau muaj kev cuam tshuam ntau tshaj plaws. Txij li -40 degrees 180% lub teeb ci, txog 120 degrees lub teeb ci tsawg dua 50%, uas yog hais, qhov ci ci ntawm lub teeb liab yog txo los ntawm ze li ntawm ob feem peb. Tus hais txog qhov tseeb, qhov zoo dua ntawm lub teeb xiav thiab lub teeb ntsuab tsis tshua muaj lub siab kub, tshwj xeeb tshaj yog lub teeb xiav. Thaum tus kub nce, muaj teeb meem. Lub ci ci ntawm LEDs ntawm cov xim sib txawv yog txawv.
3. Qhov ntsuas kub tau ua rau lub neej LED luv luv: Raws li cov ntaub ntawv ntawm ib lub chaw sim hauv Tebchaws Meskas, qhov ntsuas kub tau nce los ntawm 63C txog 74C, thiab lub neej LED raug txo los ntawm 36,000 teev rau 16,000 teev.
4. Ntau qhov sib xyaw ua kom sov tawm ua rau muaj cov nqi siab dua.
5. Nws nkim lub zog thiab ua rau cov neeg siv nce ntxiv.
Yog li cov hluav taws kub kub los qhov twg los? Los ntawm lub hwj huam hluav taws xob rau LED teeb, rau tus tsav tsheb LED, thiab tom qab ntawd mus rau qhov kho kom haum, feem cua sov suav nrog LED teeb, tus tsav tsheb LED, thiab kab txuas LED. Cia' s coj 5V fais fab mov ua piv txwv:
Fais fab mov voltage: 5V,& nbsp;
LED: LED G / B Vfwd=3.2V, LED R Vfwd=2V
1. Lub luminous efficiency ntawm LED yog li 20%, thiab LED tso cua sov tso nyiaj rau 50% ntawm tag nrho cov cua sov
2. Cov tswj hwm thiab txuas cov xov hlau tsim kom tau li 5% ntawm qhov hluav taws xob tag nrho
3. Tsav hluav taws xob tsav poob: 1.8V (G / B) lossis 3V (R) qhov hluav taws xob poob, cov cua sov ntawm cov tsav tsheb feem ntau rau ntau dua 45% ntawm tag nrho cov cua sov.
Cov cua kub ntawm LED teeb xav tau kev txhim kho lub teeb pom kev zoo ntawm LED, tus tswj thiab cov kav hlau txuas muaj tsawg cua sov, thiab tsis muaj ntau chav rau kev txhim kho. Muaj ntau ntawm chav rau kev txhim kho nyob rau hauv cov cua sov tiam tsav tsheb, thiab nws tseem yog ib feem peb cia siab rau txhim kho.
