Ibhalansi yokufuma kunye noKuchithwa koBushushu kwi-LED yangaphandle
Ukufuma kunye nobushushu obuphezulu zenza isikrini se-LED singqine ukufuma kunye nokutshabalalisa ubushushu. Indlela yokwenza umsebenzi omhle wokuthintela umswakama kwimozulu yemvula, ngelixa ugcina ukutshatyalaliswa kobushushu obuhle kwindawo yokushisa ephezulu, kuye kwaba yingxaki enzima kwizikrini ze-LED zangaphandle.
Ukuchithwa komswakama kunye nobushushu, ibini lezinto eziphikisanayo zendalo
Umboniso we-LED izixhobo zangaphakathi ngamalungu e-MSD (izixhobo ezibuthathaka zokufuma). Nje ukuba ukufuma kungene, kunokubangela i-oxidation kunye nokuhlwa kwezinto ezinje ngamaso esibane, iibhodi zePCB, izixhobo zombane, kunye neentambo zombane, ezinokubangela ukusilela kwesibane esifileyo. Ke ngoko, imodyuli, ulwakhiwo lwangaphakathi kunye ne-chassis yangaphandle yesikrini se-LED kufuneka ibe noyilo olubanzi kunye nolungqongqo lokunyakama kunye noyilo olungenamanzi.
Kwangaxeshanye, amacandelo angaphakathi kwesikrini se-LED zizinto ze-elektroniki ezidumileyo, ezinje ngeentsimbi zesibane se-LED, ii-ICs zomqhubi, izixhobo zombane ezitshintshayo, njalo njalo. Uyilo olulambathayo lokuphelisa ubushushu luyakwenza i-oxidize imathiriyeli yesikrini, echaphazela umgangatho kunye nobomi. Ukuba ubushushu buqokelela kwaye abukwazi ukubaleka, kuya kubangela ukuba iinqununu zangaphakathi ze-LED zigqithise kwaye zonakaliswe, eziza kubangela ukungaphumeleli. Ngoko ke, ukuchithwa kakuhle kobushushu kufuna isakhiwo esicacileyo kunye ne-convective, ephikisana neemfuno zokumelana nokufuma.
Ubushushu obuphezulu, ubushushu obumanzi, indlela yokufezekisa indlela ephindwe kabini.
Kwimozulu efumileyo neshushu, ejongene nokufuma kunye nokuchithwa kobushushu, oku kungangqinelaniyo kubonakala kungalungelelaniswa kunoko kusonjululwa ngobuqhetseba ngezixhobo zentsimbi ezigqwesileyo kunye noyilo olunenkathalo lolwakhiwo.
Okokuqala, ukunciphisa ukusetyenziswa kwamandla kunye nokunciphisa ukulahleka kobushushu yindlela efanelekileyo yokuphucula ukutshatyalaliswa kobushushu.
Ngaphaya koko, ukuphucula itekhnoloji yokuvelisa imodyuli ikwayeyona nto iphambili.
Ekugqibeleni, ukulungiswa okunengqiqo kwesakhiwo sebhokisi kunokudlala indima ebalulekileyo. Ukuqwalasela ukutshatyalaliswa kobushushu kunye nokuxhatshazwa kwe-oxidation ye-case material, khetha i-aluminium ephezulu. Umbindi wecala usebenzisa ubume bendawo enamaleko amaninzi ukwenza ulwakhiwo olucacileyo lokuchitha ubushushu, olunokuthi lusebenzise ngokupheleleyo umoya wendalo wokuhambisa ubushushu, kuthathelwa ingqalelo kokubini ukutshatyalaliswa kobushushu kunye nokutywinwa kunye nokuphucula ukuthembeka kunye nobomi benkonzo.
