Dab tsi yog cov khoom tseem ceeb ntawm lub vijtsam coj zaub?Muaj ntau ntau LED zaub manufacturers nyob rau hauv kev ua lag luam, thiab tus nqi ntawm tib hom LED zaub tseem txawv heev.Ib feem loj ntawm qhov laj thawj nyob hauv nws cov khoom.Qhov zoo thiab cov nqi ntawm cov khoom siv no yuav cuam tshuam rau tus nqi kawg ntawm LED zaub.Ua raws li peb hnub no Cia peb saib cov khoom ntawm cov khoom coj ua:
1. Lub rooj tsavxwm
Lub tsev board yog ib qho ntawm cov khoom tseem ceeb ntawm LED zaub.Qhov zoo ntawm pawg thawj coj saib yuav cuam tshuam ncaj qha rau cov nyhuv ntawm cov khoom coj ua.Lub tsev board yog tsim los ntawm cov coj module, tus tsav tsheb nti thiab lub pcb Circuit Court board.LED module yog tiag tiag tsim los ntawm ntau yam LED teeb-emitting point yog encapsulated nrog resin los yog yas;
Tus tsav tsheb nti yog 74HC59574HC245/24474HC1384953.
Cov feem ntau siv chav tsev board specifications rau sab hauv tsev coj cov ntxaij vab tshaus yog:
Parameter D = 3.75;dot pitch 4.75mm, dot dav * 16 dot qhov siab, 1/16 cheb sab hauv tsev brightness, ib leeg liab / liab thiab ntsuab ob xim;
Kev piav qhia Parameter
D sawv cev rau lub luminous txoj kab uas hla, uas yog hais txog lub cheeb ntawm lub luminous point D = 3.75mm;
Lub teeb-emitting point nrug yog 4.75mm, raws li qhov pom kev deb ntawm cov neeg siv, qhov chaw sab hauv tsev feem ntau xaiv 4.75;
Qhov loj ntawm chav tsev board yog 64 * 16, uas yog ib qho kev siv ntau dua chav tsev, uas yooj yim dua mus yuav thiab tus nqi kuj pheej yig;
1/16 cheb, txoj kev tswj ntawm chav tsev board;
Nyob sab hauv tsev ci ntsa iab hais txog qhov ci ntawm LED teeb-emitting teeb, thiab qhov ci ntsa iab sab hauv tsev yog tsim rau ib puag ncig uas yuav tsum tau illuminated los ntawm cov teeb fluorescent thaum nruab hnub;
Xim, ib xim yog siv ntau dua, thiab tus nqi kuj pheej yig, ob-xim feem ntau yog hais txog xim liab thiab ntsuab, thiab tus nqi yuav siab dua me ntsis;
Piv txwv tias koj xav ua ib qho screen 128 * 16, tsuas yog txuas ob chav boards hauv koob;
2. Lub zog
Feem ntau, kev siv hluav taws xob hloov pauv, 220v tawm tswv yim, 5v DC tso zis, tab sis nws yuav tsum tau muab sau tseg ntawm no tias vim tias cov khoom siv coj los siv yog cov khoom siv hluav taws xob zoo, nws yog ib qho tsim nyog yuav tsum siv lub zog hloov pauv hloov pauv hloov pauv.Rau ib leeg liab sab hauv tsev 64 * 16 Thaum lub rooj tsav xwm hauv tsev yog tag nrho ci, qhov tam sim no yog 2a;Nws tuaj yeem suav tau tias tam sim no ntawm 128 * 16 ob-xim npo yog 8a nyob rau hauv lub siab ci ntsa iab, thiab 5v10a hloov hluav taws xob yuav tsum raug xaiv;
3. Tswj daim npav
Peb pom zoo kom siv daim npav uas tsis tshua muaj nqi strip screen tswj, uas tuaj yeem tswj tau 256 * 16-dot ob-xim npo nrog 1/16 scan, thiab tuaj yeem sib sau ua ke ib qho screen LED nrog tus nqi siab dua.Daim npav tswj hwm yog daim npav asynchronous, uas yog hais tias, Daim npav tuaj yeem txuag cov ntaub ntawv tom qab fais fab tuag, thiab tuaj yeem tso saib cov ntaub ntawv khaws cia hauv nws yam tsis tas txuas nrog lub computer.Thaum muas ib lub rooj tsavxwm, koj yuav tsum sab laj cov kev txwv.Lub siab tshaj plaws chav tsev board mas muaj 08 interface, 4.75mm point nrug, 64 ntsiab lus dav thiab 16 ntsiab lus siab., 1/16 scan nyob sab hauv tsev brightness, ib leeg liab/liab thiab ntsuab ob xim;08 interface 7.62mm taw tes nrug 64 ntsiab lus dav * 16 ntsiab lus siab, 1/16 scan nyob sab hauv tsev ci ntsa iab, ib leeg liab / liab thiab ntsuab ob xim;08 interface 7.62 ntsiab lus nrug 64 ntsiab lus Dav * 16 ntsiab lus siab, 1/16 ib nrab-sweep sab nraum zoov ci ntsa iab, ib leeg liab / liab thiab ntsuab ob xim;
4. Hais txog 16PIN08 interface
Vim tias muaj ntau lub tuam txhab ntawm chav tsev boards thiab tswj cov ntawv teev lus, muaj ntau yam kev sib txuas ntawm chav tsev.Thaum sib sau ua ke lub vijtsam LED, nws yog ib qho tsim nyog kom paub meej tias qhov sib xws ntawm lub interface los pab txhawb kev sib dhos.Ntawm no peb qhia txog kev siv LED interfaces: coj kev lag luam tus lej: 16PIN08 interface, qhov sib txuas sib txuas yog raws li hauv qab no: 2ABCDG1G2STBCLK16
1 NPO1R2NN15
ABCD yog kab xaiv teeb liab, STB yog lub teeb liab latch, CLK yog lub moos teeb liab, R1, R2, G1, G2 yog cov ntaub ntawv tso saib, EN yog cov zaub muaj nuj nqi, thiab N yog hauv av.Xyuas kom tseeb tias qhov kev sib tshuam ntawm lub rooj tsavxwm thiab daim npav tswj tau zoo ib yam thiab tuaj yeem txuas ncaj qha Yog tias nws tsis sib haum, koj yuav tsum tau ua ib txoj kab hloov dua siab tshiab los ntawm koj tus kheej los hloov qhov kev txiav txim ntawm cov kab;
5. Cov kab sib txuas
Feem ntau muab faib ua cov ntaub ntawv kab, kab sib kis, kab hluav taws xob, cov ntaub ntawv kab yog tsuas yog siv los txuas rau daim npav tswj thiab LED lub rooj tsavxwm, cov kab sib txuas yog siv los txuas daim npav tswj thiab lub computer, cov kab hluav taws xob yog siv los txuas. lub hwj huam mov thiab tswj daim npav fais fab mov thiab lub rooj tsavxwm coj lub rooj tsavxwm, cov tub ntxhais tooj liab ntawm cov kab hluav taws xob txuas nrog lub rooj tsavxwm yuav tsum tsis pub tsawg dua 1 hli inch;
Cov saum toj no yog cov khoom ntawm cov qauv ntawm cov xim puv xim LED.Hauv cov ntsiab lus, feem ntau yog chav tsev boards, cov khoom siv hluav taws xob, cov ntawv tswj hwm, cov kab txuas, thiab lwm yam. Kuv vam tias tsab xov xwm no tuaj yeem pab tau rau koj.Yog tias koj xav paub ntau ntxiv txog cov qauv ntawm LED zaub kev paub, koj tuaj yeem txais tos txuas ntxiv.
