Cov teeb pom kev ntawm LED yog cov peev txheej qis thiab cov kev daws teeb meem yooj yim tsim rau niaj hnub siv hauv qhov tsaus ntuj lossis rau teeb pom kev zoo nkauj. Qhov yooj yim LED teeb nyem yuav luag los ntawm thawj xyoo ntawm kev tsim khoom tau muab txoj hauv kev rau lub teeb ci thiab LED cov kab xev.

Kev xaiv cov txheej txheem rau cov hlua LED

Ua ntej tshaj plaws, daim kab xev teeb pom kev zoo raug xaiv raws li lub zog ntawm ib lub meter linear - nws sib npaug 4, 8-19, 2 watts. Kev siv hluav taws xob nyob ntawm tus naj npawb ntawm LEDs ntawm txhua lub ntsuas kab xev, nrog rau kev ntsuas ntawm txhua lub teeb pom kev txiav txim los ntawm kev kos (qauv lossis koob).

Qhov thib ob yog qhov ntev ntawm cov kab diode hauv cov kauj - los ntawm 5 txog 100 m. Cov ntsiab lus txiav tawm - lawv tau nrog lub cim cim zoo ib yam li txiab - hauv kab xev rau cov khoom siv hluav taws xob ntawm 12 thiab 24 volts nyob txhua ob peb centimeters . 220 V kab xev tsuas tuaj yeem txiav txhua txhua ib nrab 'meter' lossis 'meter' - kev sib txuas ntawm cov pab pawg loj ntawm LEDs tsis tso cai txiav lub teeb hauv cov pab pawg me.

Thaum kawg, qhov dav ntawm lub teeb ci nyob ntawm tus naj npawb ntawm cov xim ntawm lub teeb tso tawm. LED sawb yog tsim nyob rau hauv daim ntawv ntawm cov thev naus laus zis hloov pauv tau yooj yim luam tawm lub rooj tsavxwm, qhov dav uas txawv ntawm ob peb millimeters mus rau ntau dua ib centimeter. Cov kev hloov pauv raug yog 3, 4, 5 thiab 6 mm lub teeb ci dav dav . Cov txiaj ntsig loj, siv feem ntau rau txoj kev thiab lwm yam teeb pom kev sab nraud, yog 8, 10 thiab 10, 2 mm.

Cov nqaim - lossis dav dua - cov kab ntawv kuj tseem tab tom tsim: yav dhau los sib tw nrog cov kab xev LED, tom kawg nrog cov kab txaij sib dhos, nce mus txog qhov ua tau zoo rau cov teeb pom kev zoo siv hauv cov dej nyab.

Cov kab xev muaj qhib (tsis tiv thaiv los ntawm ya raws) thiab kaw . Kaw daim kab xev - cov ntsiab lus lub teeb - ntawm cov phaj hloov tau yooj yim hauv cov txheej txheem pob tshab pob tshab ua los ntawm kev pov tseg. Lub thickness ntawm daim kab xev qhib - los ntawm 2 hli, kaw - txog li ib centimeter, ua ke nrog cov txheej silicone. Daim kab xev kaw tuaj yeem siv hauv chav uas muaj cov av noo siab, los nag lossis tso dej rau hauv dej-cov xwm txheej yog lub luag haujlwm rau chav tiv thaiv dej noo los ntawm IP-65 txog IP-69. Cov kab xev uas tsis tiv thaiv dej tau muab cais ua IP-20-IP-40.

Hom thiab ntau yam ntawm LEDs

Tau txiav txim siab qhov dav, tuab, ntev thiab lub zog (lub teeb tawm) daim kab xev xav tau, nws tsis yog qhov xav tau kom meej meej uas LEDs tau siv hauv kev tsim cov kab xev, cov kauj uas tus neeg siv xav yuav.

Yog li, SMD-3528 LEDs yog tus yam ntxwv zoo haum, txawm li cas los xij, lawv cov yam ntxwv ua kom sov tawm mus yog qhov pom tsis zoo dua li ntawm SMD-5050 lub teeb pom kev.

Vim yog qhov cua sov tsis zoo, koj yuav tsum tau ceev faj heev thaum siv lub SMD-3528 LEDs: nws yog qhov zoo dua kom txo qis qhov hluav taws xob me ntsis, thiab nrog nws cov teeb pom kev tawm mus. Yog tias lub cua sov tsis muaj sijhawm los rau hauv cov hlau lossis cov khoom sib xyaw ua ke, LED yuav ua kom sov ntau dhau hauv ob peb feeb. Ua haujlwm tau ua kom sov dhau-qhov kub ntawm LED nce mus txog 42-75 degrees-lub teeb pom kev zoo yuav hlawv tawm tom qab ob peb puas lossis ob peb txhiab teev ntawm kev ua haujlwm txuas ntxiv, txij li nws tau hu ua kev ua haujlwm ntawm cov yam ntxwv tam sim no-voltage tau ua txhaum, thaum kawg nkag mus rau thaj tsam ntawm cov cua sov tawg, uas tsis tuaj yeem lees txais.

Nta ntawm daim kab xev fais fab mov

Qee cov kws tshaj lij qhia ntxiv nrog rau kev txo qhov hluav taws xob txo qhov hluav taws xob hauv cov kab hluav taws xob LED . Xijpeem siv lub zog hloov kho tau lossis tus tsav tsheb uas qhov hluav taws xob (lossis tam sim no) tau teeb tsa siv tus qauv tiv thaiv tus qauv swb uas ua raws li hom potentiometer. Hauv qhov no, ntawm lub LED dawb, qhov hluav taws xob yuav tsum yog kwv yees li 3 V (2, 7-3, 3 raug tso cai), ntawm cov xim - liab, daj, xiav lossis ntsuab - txog 2 V (qhov zoo tshaj 1, 8-2, 2). Qhov no siv rau lub teeb ci ntawm txhua qhov dav, lub zog thiab tus naj npawb ntawm LEDs rau ib kab ntsuas kab.
