Feem ntau hais lus, LED teeb hlaws yog tiag tiag lub teeb-emitting diode, uas yuav emit lub teeb tom qab loaded nrog ib tug tej yam voltage thiab tam sim no. Feem ntau hais lus, qhov hluav taws xob ntawm ib qho LED nti yog li 3V thiab tam sim no yog 30mA. Rau qhov hluav taws xob thiab tam sim no ntawm LED teeb hlaws, feem ntau ntawm LED teeb hlaws ntim txheej txheem, kev sib raug zoo ntawm cov teeb ci LED hlaws hlaws yog txiav txim siab. Hauv qab no yog cov lus piav qhia ntxaws txog GMKJ LED rau txhua tus!
Feem ntau siv 0.2W LED teeb hlaws hauv lub teeb raj yog tsim los ntawm ob lub LED chips nyob rau hauv parallel, uas yog 3V, 60MA. Raws li rau high-voltage LED 9V teeb hlaws dai uas feem ntau yog siv rau kev tiv thaiv-capacitance fais fab mov, nws yog tsim los ntawm peb LED chips nyob rau hauv series, namely 9V, 30MA.
Vim hais tias LED teeb hlaws yog tsim los ntawm ntau lub LED chips nyob rau hauv series thiab parallel, muaj ntau yam specifications ntawm LED teeb hlaws dai. Shenzhen high-qib LED teeb hlaws hom GMKJ LED 3030LED teeb hlaws tuaj yeem tsim thiab muab hluav taws xob 3030LED teeb hlaws. zoo. Lub teeb hlaws tshwj xeeb' s V tuaj yeem pom los ntawm ntau npaum li cas LED chips lub teeb hlaws yog tsim los ntawm. Tau kawg, vim hais tias LED nti yog me me thiab cov hlau nplaum kub hlau kuj tseem me me, kev tshuaj xyuas qhov muag tsuas yog kwv yees. Qhov tshwj xeeb tseem yog Nws yuav paub tsuas yog tom qab ntsuas nrog DC qhov chaw.
Txawm li cas los xij, 3V, 6V, 9V, thiab lwm yam yog siv ntau dua. Tau kawg, tseem muaj kaum tawm V teeb hlaws. Qhov no nyob ntawm
Txoj kev npaj tsim tshwj xeeb txiav txim siab seb lub teeb hlaws siv li cas.
Rau 3030LED teeb hlaws nrog tsuas yog ib qho hluav taws xob me me, koj tuaj yeem siv cov ntaub ntawv diode ntawm multimeter los teeb lub 3030LED teeb hlaws. Qhov no yog qhov zoo thiab qhov tsis zoo. Yog tias nws tsis nyob rau, cia li hloov qhov zoo thiab qhov tsis zoo. Rau LED teeb hlaws dai nrog qhov tsis paub qhov hluav taws xob, nws tsuas yog ntsuas tau nrog DC qhov chaw. Txoj kev yog: kho qhov DC qhov hluav taws xob mus rau xoom, kho qhov tam sim no mus rau qhov siab tshaj plaws, txuas cov ncej zoo thiab tsis zoo ntawm lub teeb hlaws, thiab kho qhov voltage ntawm cov cai tam sim no kom nws pib ntawm xoom kom nce, thaum lub Lub teeb hlaws yog dimly lit, qhov voltage ntawm lub sijhawm no yog kwv yees voltage ntawm LED teeb hlaws.
GMKJ LED, LED teeb hlaws, LEDSMD, SMD qhov taw qhia, LED backlight teeb hlaws, LED ob-xim teeb hlaws, RGB teeb hlaws, LED pob taub hau teeb hlaws, LED ob xim teeb hlaws, LED ib leeg RGB teeb hlaws, LED sab Lub teeb hlaws, LED monochromatic teeb hlaws, LED nws tus kheej-flashing teeb hlaws, LED magic teeb hlaws, LED infrared teeb hlaws, LED ultraviolet teeb hlaws
Rau COB teeb hlaws, nws yog qhov tseeb, tab sis COB encapsulates ntau LED chips, qhov voltage thiab tam sim no yuav loj heev. Cov txheej txheem ntawm kev lees paub qhov voltage thiab tam sim no ntawm COB teeb hlaws kuj yog kom paub meej nrog DC qhov chaw.
Siv DC qhov chaw kom paub meej tias qhov no yog txoj kev yooj yim tshaj plaws thiab tsis zoo. Nws yog siv ntau tshaj plaws hauv txoj kev loj hlob. Thaum plagiarizing lwm tus neeg' lub teeb, qhov no kuj yog txoj hauv kev kom paub meej cov lus qhia ntawm lub teeb hlaws siv los ntawm lwm tus.
Cov qib high-qib LED teeb hlaws hom GMKJ LED tau hais tias txhua qhov kev qhia ntawm lub teeb hlaws muaj nws tus yam ntxwv, qee qhov muaj txiaj ntsig zoo dua, thiab qee qhov muaj kev ua tau zoo dua. Thiab LED teeb hlaws ntawm tib lub ntsiab lus ntawm txhua qhov chaw tsim khoom yuav txawv, yog li tsis muaj qhov zoo ntawm 3030LED teeb hlaws, tsuav nws siv tau zoo, nws yuav ua lub luag haujlwm loj tshaj plaws.
