Kev faib tawm LED:
Raws li lub zog loj: muaj peev xwm muab faib ua lub zog me, lub zog loj (hauv kev lag luam, feem ntau ntau dua li 0.5W teeb hu ua lub teeb loj zog)
Raws li cov duab: tuaj yeem faib ua-hauv kab thiab thaj
Lub teeb lub kaus mom LED tuaj yeem muab faib ua F3 raws li qhov loj me ntawm lub taub hau teeb (lub taub ntawm lub taub hau teeb yog 3 hli), F5 (lub taub ntawm lub taub hau teeb yog 5mm); los yog cais rau hauv cov duab ntawm lub hauv paus tsis muaj ntug, sab sab, tuab sab, puag ncig taub hau; Pob tshab los yog tsis tuaj yeem muab faib ua pob tshab, qhov muag. Ntau cov txheej txheem tsis muaj npe, thiab cov npe saum toj no tsuas yog ua los ntawm kev siv peb lub tuam txhab ntau dhau.
Lub piranha LED tseem tuaj yeem faib ua F3, F5 raws li qhov loj me ntawm lub taub hau teeb. Raws li cov duab ntawm lub taub hau teeb, nws muab faib ua cov hau taub hau (uas yog, piranha teeb feem ntau), thiab lub taub hau tiaj (hom taub hau no tshwj xeeb heev, nws lub teeb lub teeb yog ze li 180 degrees, feem ntau Siv nyob rau hauv cov xwm txheej uas xav tau astigmatism).
Lub zog hluav taws xob me me SMD LEDs tuaj yeem faib ua 0805, 1206, 3020, 3528, 5050 lossis 5060 raws li lawv qhov ntev sab nraud (5050 thiab 5060 yog tsawg heev, nyuaj rau qhov txawv ntawm qhov muag tsis pom, thiab tuaj yeem hu los ntawm cov neeg siv khoom uas tsis tshaj lij txaus).
High-power LEDs feem ntau muab faib los ntawm lub zog. Nquag siv yog 0.5W, 1W, 3W, 5W, thiab 8W.
Tib lub teeb ci LED, qhov tshwj xeeb tshaj plaws tsuas yog siv ib nti xwb, tab sis yog muaj xwm txheej tshwj xeeb tuaj yeem siv ob lossis plaub kis sib tw, xws li: ib lub xov mom taws lub teeb tuaj yeem siv ib lossis ob daim me me (suav tias nws loj me, tshav kub kev tsis sib haum xeeb tsis yog yooj yim ua rau cov kev ua tsis ruaj khov uas siv tsuas yog ib lossis ob daim txiag ntoo); ib lub piranha teeb siv tau ib qho, ob, peb, plaub, plaub daim me, feem ntau siv ib qho yog ob thiab ob daim nti; thaj 3528 tuaj yeem siv nrog ib, ob, peb daim nyias nyias, thaj 5050/5060 feem ntau siv peb chips. Daim ntawv qhia tshwj xeeb: Thaum siv peb lub chips rau lub teeb thaj, muaj ob rooj plaub:
1. Peb chips yog zoo tib yam xim
2. Peb lub chips yog xim liab, ntsuab thiab xiav, uas yog lub teeb RGB peb feem ntau hais.
LED lub kaum sab xis Pom qhov txiav txim siab:
Feem ntau lub kaum sab xis ntawm lub teeb pom kev zoo rau cov ntsaws rau hauv LED yog 120 degrees, thiab tshwj xeeb tuaj yeem ua tiav ntawm 45 degrees, lossis 15 degrees. Peb cov khoom siv hluav taws xob hauv kab hluav taws xob feem ntau yog li 120 degrees, cov hlua hluav taws xob silicone yog siv ntawm 45 degrees; thaj LEDs feem ntau muaj lub teeb pom kev zoo ntawm 120 degrees.
LED hluav taws xob txiav txim siab:
Ib qho qis hluav taws xob LED teeb, nyob rau hauv cov xim sib txawv, yuav tsum muaj qhov sib txawv. Liab / daj: feem ntau 1.8 ~ 2.1 volts, dawb / ntsuab / xiav: feem ntau 3.0 ~ 3.6 volts. Cov voltage uas yuav tsum tau rau 1W siab zog teeb yog tib yam li saum toj no.
LED tam sim no (tam sim no) txiav txim siab zoo:
1. Cov teeb hluav taws xob qis LED (nrog rau ntsaws lossis thaj), qhov tso cai tam sim no ntawm txhua nti yog feem ntau tsis siab tshaj 20 mA; qhov tam sim no tau tso cai kom dhau mus rau ntawm txhua ob-nti teeb yog feem ntau tsis siab dua 40 mA. Zoo sib xws, txhua peb-nti teeb yuav tsum tsis txhob siab tshaj 60 mA.
2. Rau cov hluav taws xob muaj zog LED, peb tau siv 1W, uas tso cai tam sim no ntawm 150 mA.
