Dawb LED teeb hlaws tsis ua hauj lwm los yog necrosis ntawm lub ntsiab lus tseem ceeb
Cov Tub Ntxhais Cov Ntawv Teeb: cov teeb dawb LED teeb yog cov khoom siv hluav taws xob, cov khoom ntim hauv ntau cov pob ntawv muaj kev khiav hauj lwm tam sim no thiab kev khiav hauj lwm muaj hluav taws xob, nyob rau hauv ib lub hnab ntawv (piv txwv li 2835); nyob rau hauv cov hauj lwm tseeb ntawm cov teeb ci teeb ntawm cov teeb ci dawb yog cov khoom siv hluav taws xob, cov khoom ntim hauv ntau lub pob raws li kev khiav hauj lwm tam sim no thiab kev khiav hauj lwm muaj hluav taws xob, nyob rau hauv ib lub hnab pob (2835); nyob rau hauv cov hauj lwm tseeb yog rau 60mA tam sim no rau lub siab txwv, tiam sis feem ntau vim kev siv ntawm cov ntau yam ua rau kev nce zuj zus ntxiv, yog tias tsis siv kev ntsuas, qhov nce ntawm qhov tam sim no tshaj ib lub sij hawm thiab qhov siab tom qab lub teeb ci LED teeb yuav raug puas ntsoog.
Cause LED teeb hlaws puas yog vim li cas tseem ceeb tshaj:
① Sudable nce nyob rau hauv lub zog mov voltage, dhau lub teeb zog supply voltage ntau, ua rau muaj zog zis hluav taws xob, yog li lub teeb cov hlaws hlawv.
② ib feem ntawm txoj kab lossis kab hluav taws xob lossis lwm yam luv luv thiab tsim teeb ntawm cov teeb uas muaj teeb pom kev zoo ntawm lub teeb nrig hauv lub nroog, kom lub zos qhov hluav taws xob nce, thiab hlawv lub teeb lossis lwm yam khoom ntawm lub rooj tsav xwm hauv circuit.
③ ib cov hlaws LED teeb vim lawv tus kheej kev puas tsuaj thiab yog li tsim cov luv luv Circuit Court, nws yog qhov cim tseg qhov hluav taws xob tau dhau mus rau lwm cov teeb ci LED teeb.
④ kub kub yog siab dhau, thiaj li tias LED teeb hlaws tam sim no nce, yog li ntawd cov hlaws roj hlawv hlawv.
⑤ cov hlaws ntim tsis ua dej tsis tau kho, qhov ntxig qhov tsim nyog rau daim ntawv yoojyim, ua rau cov kab los yog cov roj teeb hlawv hlawv.
Yog li ntawd, yuav ua li cas peb thiaj tsis zam cov teeb meem saum toj no, kev tiv thaiv ntawm cov teeb ci ntsa iab LED teeb?
Ua ntej, kom tsis txhob muaj qhov teeb meem ntawm thawj qhov teeb meem peb yuav tsum tau ntsuas.
Lub hwj huam yog feem ntau qhov sib pauv ntawm 180 ~ 240V AC fais fab ntawm lub rectifier, lim, tus tswj kom paub meej tias qhov hluav taws xob tsawg tsawg ntawm 12 ~ 72V DC fais fab teeb lub teeb ci rau siv.
1, los txhim kho cov kev ua tau zoo ntawm lub hwj chim, nws thiaj li muaj qhov dav dav hluav taws xob; feem ntau tau lav 130V ~ 265V input voltage, cov zis voltage hloov li ntawm 3% ntau.
2, Nyob rau hauv cov zis ntawm tus neeg tswj qhov tsim kom muaj qhov teeb meem tawm ncaj qha tam sim no, kom lub teeb tam sim no tsis hloov nrog cov tswv yim hloov voltage.
Thib ob, kom tsis txhob tshwm sim ntawm qhov teeb meem thib ob thiab peb yuav tsum tau ntsuas
1, Qhov xaiv ntawm lub teeb hlaws kom deb li deb tau siv cov khoom tsim nyog los ua kom muaj kev ruaj ntseg ntawm lub teeb pom kev zoo.
2, Lub teeb pom kev ntawm lub teeb pom kev zoo hauv pawg thawj coj saib tsawg li sai tau rau nruab cov khoom siv Circuit Court, nws yog qhov zoo tshaj plaws rau nruab ib cov hlaws cov teeb thiab niaj hnub IC. Cov nram qab no yog tib yam li "
Thib peb, kom tsis txhob muaj teeb meem thib plaub thiab thib tsib tshwm sim peb yuav tsum tau ntsuas
1, Yuav kom paub tseeb tias qhov kub ntawm qhov teeb yog tsis siab, nce qhov chaw txias txias, kom paub meej tias qhov chaw txias ntawm W 50 square metres.
2, T nws lub teeb txawb yuav tsum ua tiav nrog epoxy resin ua kev kho tsis ywg dej, kom tsis txhob muaj qhov teeb ntawm cov teeb ntawm lub teeb vim cov huab cua thiab qhov ua kom sov.
Mus xaus:
Tab sis nyob rau hauv cov txheej txheem ntau lawm peb tau ua cov kev ntsuas saum toj no tsis yog yooj yim, tab sis nyob rau hauv lub chaw lag luam uas twb muaj lawm los ua kom tau raws li cov qauv saum toj no, nyob rau hauv cov kev mob uas twb muaj lawm yuav ua rau cov nqi tsim ntawm cov khoom ntau, li ntawd peb cov khoom muag Yog nce, peb poob qhov nqi ntawm tus nqi. Yuav ua li cas peb yuav ua li cas nyob rau hauv ib tes los txhim kho qhov zoo ntawm cov khoom, tus nqi nqes dua?
