Isaziso seSicelo seDiode eLuminous 3535

3535 amaso isibane isibane LED zinenzuzo eyodwa, kodwa amaso isibane LED sisemngciphekweni semiconductor imveliso, ngoko ke kufuneka silumke xa usebenzisa iimveliso LED. Ngoku siza kushwankathela ezinye izilumkiso zokusetyenziswa kwe-LED. Nceda ubeke ukubaluleka okukhulu kuyo. (1) Umbane kufuneka usetyenziswe kubonelelo lombane lweDC. Abanye abavelisi babenzi kufuneka basetyenziswe ukwenzela ukunciphisa iindleko zemveliso. “Uxhathiso ”Amandla kwiimveliso ze-LED ngendlela, eya kuchaphazela ngokuthe ngqo ubomi bemveliso yesibane se-LED. Ukwamkela unikezelo lwamandla okutshintsha okukhethekileyo (ngokukhethekileyo umthombo womlambo ongaguqukiyo) unikezelo lwemveliso kwiimveliso zesibane sesibane se-LED aluyi kuchaphazela ubomi benkonzo yemveliso, kodwa ixabiso lemveliso liphezulu. (2) Amanyathelo okuchasana nombane kufuneka athathwe kwinkqubo yokusetyenzwa nokuveliswa kwamaso esibane se-LED. Iiglavu, njl.njl., abo banemiqathango banokufakelwa iifeni ze-ion ezichasene ne-static, kwaye baqinisekise nokufuma kweworkshop malunga ne-65%, ukuze kuthintelwe umoya ukuba wome kakhulu ukuvelisa umbane ongatshintshiyo, ngakumbi umbane oluhlaza. Amaso isibane LED kulula nokonakaliswa umonakalo electrostatic. Ukongeza, umgangatho owahlukileyo -umgangatho we-LED anti-static amandla nawo ahlukile. Izibane ze-LED ezinomgangatho ophezulu womgangatho kufuneka zomelele. Kusenokubakho abahlobo abaninzi abangawazi kakuhle umbane omileyo. Ndiza kwazisa ulwazi lombane ongatshintshiyo ngokweenkcukacha apha: undoqo wombane ongatshintshiyo yintlawulo eyongezelelekileyo. Intlawulo ngumthamo wenyama yawo wonke undoqo wombane ongatshintshiyo. IsiNgesi sibizwa ngokuba yi-ESD. Izixa ezihambelanayo ezinxulumene nokubanakho, indawo yombane, okwangoku, njl. zonke izixa ezibonakalayo ezibangelwa ubukho bentlawulo okanye ukuhamba kwentlawulo. Iingxaki ezininzi ze-electrostatic zibangelwa ngabantu abangenalwazi lwe-ESD. Ngoku, abantu abaninzi bakrokrela ukuba i-ESD iza kubangela umonakalo kwiimveliso zombane. Oku kungenxa yokuba uninzi lomonakalo we-ESD wenzeka ngaphantsi kweemvakalelo zomntu, kuba amandla ombane obonwa ngumzimba womntu wokukhupha okumileyo malunga ne-3KV, kwaye uninzi lwezixhobo ze-elektroniki ziya konakaliswa xa zingamakhulu eevolthi okanye iivolthi ezininzi. Ngokuqhelekileyo, xa izixhobo zombane zonakaliswe yi-ESD Akukho mda ocacileyo, kwaye icandelo lifakwe kwi-PCB ngaphambi kokufunyanwa. Ngenxa yoko, kukho iingxaki ezininzi, kwaye uhlalutyo lunzima kakhulu. Ngokukodwa kumonakalo onokwenzeka, kunzima ukulinganisa ukusebenza kwayo kunye nezixhobo ezichanekileyo, ngoko zombini iinjineli ze-elektroniki kunye nabaqulunqi baye bakrokrela i-ESD. Kwiminyaka yakutshanje, uvavanyo luqinisekisile ukuba lo monakalo onokwenzeka uya kuba Ukuthembeka kuncipha kakhulu. (3) Ubushushu besibane se-LED kufuneka sinikele ingqalelo ekwandeni kobushushu kuya kwenza ukuxhathisa kwangaphakathi kwamaso wesibane se-LED kuncinci. Emva kokunyuka kobushushu bendalo belizwe langaphandle, ukuchasana kwangaphakathi kwezibane ze-LED kuya kuncitshiswa. Ukunyuka kwangoku, xa ukusebenza kwangoku kudlula umsebenzi olinganisiweyo, kuya kuchaphazela ubomi benkonzo yeemveliso ze-LED, eziya kubangelwa kakhulu yizibane zesibane se-LED. “Ukutshisa ”Ngoko ke, kungcono ukusebenzisa umbane womthombo weHengli ukuqinisekisa ukuba ukusebenza kwangoku kwe-LED akuchaphazeli ukushisa kwangaphandle. Ubushushu bezibane ze-LED bukwayeyona nto ibalulekileyo echaphazela ubomi be-LED. Nceda unike ingqalelo kuyo. (4) Ukutywinwa kweemveliso zesibane se-LED, kungakhathaliseki ukuba yintoni imveliso yesibane sesibane se-LED, ngokude nje isetyenziswe ngaphandle, ijongene nengxaki yokungena kwamanzi kunye neengxaki zokutywinwa kobumanzi. Ukuba ayiphathwa kakuhle, iya kuchaphazela ngokuthe ngqo ubomi benkonzo yeemveliso ze-LED. Ngoku kukho inani elincinci labavelisi abaneemfuno zomgangatho ophezulu wemveliso bamkele i-epoxy resin yendabuko “Amanzi ”Indlela yokutywina iimveliso ze-LED. Le ndlela inzima ngakumbi ukusebenza. Ayifanelekanga kakhulu kwiimveliso zesibane se-LED ezinomthamo omkhulu, kwaye iya kwandisa ubunzima bemveliso. 5 (6) Amaso isibane LED kufuneka ingqalelo amaso isibane LED kufuneka angasondeli kakhulu colloid xa ikona okanye engile igobile. Kufuneka igcinwe kumgama ongaphezu kwe-2mm ukusuka kwi-colloid. Inani lokugotywa kwinqanaba alikwazi ukuba ngaphezu kwamaxesha amathathu, kwaye ikona igobile 90 °Buyela kwindawo yokuqala kanye. (7) Ukushisa kwe-welding yokushisa kwe-welding malunga ne-260 C, ixesha lilawulwa ngaphakathi kwe-5s, kwaye indawo ye-welding ingaphezulu kwe-2.5mm ukusuka ezantsi kwe-colloid.
