Kugwa ndi nyengo yozizira ndi nthawi yayitali ya kulephera kwa zida zamagetsi, ndipo zowonetsera za LED sizili choncho.Monga mkulu-mtengo mwatsatanetsatane zinthu zamagetsi, mmene ntchito yabwino m'dzinja ndi yozizira LED anasonyeza kukonza, kuwonjezera pa kufunika kuchita ntchito yabwino yokonza wamba, komanso ayenera kupereka chidwi chapadera pa mbali zitatu zotsatirazi. : magetsi osasunthika, condensation ndi kutentha kochepa.
Electrostatic protection ndiyofunikira kwambiri, kuti muchite ntchito yabwino yachitetezo cha electrostatic iyenera kumvetsetsa komwe kumachokera magetsi osasunthika.Malinga ndi chiphunzitso cha atomic physics, zinthuzo zili mumagetsi amagetsi pomwe sizilowerera pamagetsi.Chifukwa cha kupindula ndi kutayika kwa ma electron opangidwa ndi kukhudzana kwa zinthu zosiyanasiyana, zinthuzo zimataya mphamvu zamagetsi ndipo zimapanga chodabwitsa cha electrostatic.Kukangana pakati pa matupi kumatulutsa kutentha ndikusangalatsa kusamutsa kwa ma elekitironi;Kulumikizana ndi kulekana pakati pa matupi kumatulutsa kusamutsidwa kwa ma elekitironi;Electromagnetic induction imabweretsa kugawa kosakwanira kwa charger pamwamba pa chinthucho.Kuphatikizika kwa kukangana ndi electromagnetic induction.
Magetsi osasunthika ndi wakupha wamkulu wa chiwonetsero cha LED, sichidzangochepetsa moyo wa chiwonetserochi, komanso chidzatulutsa chiwonetsero chazowonongeka zamkati mwamagetsi, kuwononga chinsalu.Kaya zowonetsera za LED zamkati kapena zowonetsera zakunja za LED, ndizosavuta kupanga magetsi osasunthika pakagwiritsidwe ntchito, kubweretsa zoopsa pachiwonetsero.Chitetezo cha Electrostatic: Kuyika pansi ndiye njira yabwino kwambiri yolimbana ndi ma static popanga, ogwira ntchito ayenera kuvala chibangili chokhazikika cha electrostatic.Makamaka podula phazi, pulagi-mu, debugging ndi positi kuwotcherera, ndi kupanga kuwunika bwino, ogwira ntchito khalidwe ayenera kuyesa static chibangili osachepera maola awiri aliwonse;Ogwira ntchito akuyenera kuvala zibangili zokhazikika pakupanga.Makamaka podula phazi, pulagi-mu, debugging ndi positi kuwotcherera, ndi kupanga kuwunika bwino, ogwira ntchito khalidwe ayenera kuyesa static chibangili osachepera maola awiri aliwonse;Gwiritsani ntchito dalaivala wamagetsi otsika a DC okhala ndi waya pansi ngati kuli kotheka panthawi yomanga.
Condensation imakhalanso chiwopsezo chachikulu pakuwonetsa kwa LED, komanso kuvulaza kwakukulu kwa mawonekedwe akunja.Ngakhale zowonetsera panja amapangidwa kuti madzi, condensation amayamba chifukwa condensation wa nthunzi madzi kuchokera mlengalenga, ndi m'malovu ang'onoang'ono akhoza kumamatira PCB bolodi ndi gawo pamwamba pa chiwonetsero.Ngati chithandizo chamadzi sichinachitike bwino, bolodi la PCB ndi gawo lidzawonongeka, zomwe zimapangitsa moyo wocheperako kapena kuwonongeka kwa chiwonetsero cha LED.Yankho lake ndikusankha chotchinga chotchingira madzi pogula chophimba chowonetsera, monga chosavuta kufikira mndandanda wa Helios, kapena pazithunzi zopaka utoto wamitundu itatu.
Malo otsika kutentha angakhudzenso ntchito ya chiwonetsero cha LED, ambiri panja LED anasonyeza kutentha osiyanasiyana ndi -20 ℃ kuti 60 ℃, kutentha otsika kwambiri kungachititse kuti ntchito zina semiconductor zigawo zikuluzikulu yafupika, kapena sangakhoze kuyamba bwinobwino, ndi pulasitiki ena. Zigawo zimatha kusweka chifukwa cha kutentha kochepa.Choncho, pogula chophimba chowonetsera cha LED, yesetsani kumvetsera kutentha kwake, musayatse chophimba cha LED pamene kutentha kuli kochepa kwambiri, ndipo nthawi zonse fufuzani ngati chinsalucho chawonongeka, ngati kuzizira kwambiri kungathe kuwonjezeredwa. chophimba chowonetsera chokhala ndi chipangizo cha mpweya wotentha.
Mfundo zitatu zomwe zili pamwambazi ndi nyengo ya autumn ndi nyengo yachisanu, kukonza zowonetsera za LED kumafuna chisamaliro chowonjezereka.
