Izibane ze-LEDlukhetho oludumileyo lokukhanyisa ngenxa yokusebenza kakuhle kwamandla abo, ubomi obude, kunye nokukhanya okukhethekileyo. Kodwa ngaba wakha wazibuza ukuba zenziwa njani ezi zibane zingaqhelekanga? Kweli nqaku, siza kuphonononga inkqubo yokwenziwa kwezibane ze-LED kunye nezinto ezizenza zisebenze ngokufanelekileyo.
Inyathelo lokuqala ekudaleni isibane se-LED kukukhetha imathiriyeli efanelekileyo. Izinto eziphambili ezisetyenziswayo zii-LED ezikumgangatho ophezulu, izixhobo ze-elektroniki, kunye neesinki zobushushu ze-aluminium. Itshiphu ye-LED yintliziyo yesibane kwaye idla ngokwenziwa ngemathiriyeli ye-semiconductor efana ne-gallium arsenide okanye i-gallium nitride. Ezi zixhobo zigqiba umbala okhutshwe yi-LED. Emva kokuba izinto zifunyenwe, inkqubo yokuvelisa ingaqala.
Iichips ze-LED zifakwe kwibhodi yesekethe, eyaziwa ngokuba yiPCB (ibhodi yesekethe eprintiweyo). Ibhodi isebenza njengomthombo wamandla we-LEDs, ilawula okwangoku ukugcina izibane zisebenza ngokufanelekileyo. Faka i-solder paste ebhodini kwaye ubeke i-chip ye-LED kwindawo echongiweyo. Indibano yonke ke ifudunyezwe ukunyibilikisa i-solder paste kwaye ibambe i-chip endaweni. Le nkqubo ibizwa ngokuba yi-reflow soldering.
Into elandelayo engundoqo yesibane sesikhukula se-LED yi-optics. I-Optics inceda ukulawula indlela kunye nokusasazeka kokukhanya okukhutshwa zii-LEDs. Iilensi okanye izibonisi zihlala zisetyenziswa njengezinto ezibonakalayo. Iilensi zinoxanduva lokwahlula ukukhanya, ngelixa izipili zinceda ukukhanya kwiindlela ezithile.
Emva kokuba indibano ye-chip ye-LED kunye ne-optics igqityiwe, i-electronic circuitry ihlanganiswe kwi-PCB. Le sekethi yenza i-floodlight isebenze, ivumela ukuba ilayite kwaye icime kwaye ilawule ukukhanya. Ezinye izibane ze-LED zesikhukula zikwabandakanya iimpawu ezongezelelweyo ezifana ne-motion sensors okanye i-remote control capabilities.
Ukuthintela ukushisa, izibane ze-LED zifuna i-heat sinks. Iisinki zobushushu zihlala zenziwe nge-aluminiyam ngenxa ye-thermal conductivity egqwesileyo. Inceda ukutshabalalisa ubushushu obugqithisileyo obuveliswa zii-LEDs, ukuqinisekisa ubomi obude kunye nokusebenza kakuhle. Isinki sobushushu sixhonywe ngasemva kwePCB ngezikrufu okanye i-thermal paste.
Nje ukuba amacandelo ahlukeneyo adityaniswe kwaye adityaniswe, izindlu ze-floodlight zongezwa. Ityala alikhuseli kuphela amacandelo angaphakathi kodwa libonelela ngobuhle. Izivalo zihlala zenziwe nge-aluminiyam, iplastiki, okanye indibaniselwano yezi zimbini. Ukukhethwa kwezinto eziphathekayo kuxhomekeke kwizinto ezifana nokuqina, ubunzima kunye neendleko.
Uvavanyo lolawulo lomgangatho olucokisekileyo luyafuneka phambi kokuba izibane ze-LED ezidityanisiweyo zilungele ukusetyenziswa. Olu vavanyo luqinisekisa ukuba isibane ngasinye sidibana nemigangatho ethile ngokuqaqamba, ukusetyenziswa kwamandla, kunye nokuqina. Izibane zikwavavanywa kwiindawo ezahlukeneyo, kubandakanywa ubushushu kunye nomswakama, ukuqinisekisa ukuthembeka kwazo kwiimeko ezahlukeneyo.
Isinyathelo sokugqibela kwinkqubo yokuvelisa ukupakisha kunye nokusabalalisa. Izibane zeMkhukula ze-LED zipakishwe ngononophelo kunye neelebhile zokuthumela. Emva koko zisasazwa kubathengisi okanye ngokuthe ngqo kubathengi, ukulungele ukufaka kunye nokubonelela ngokukhanya okukhanyayo kunye nokusebenzayo kwezicelo ezahlukeneyo, kubandakanywa amabala ezemidlalo, iindawo zokupaka, kunye nezakhiwo.
Lilonke, inkqubo yokwenziwa kwezibane zezikhukhula ze-LED ibandakanya ukukhethwa ngokucokisekileyo kwezinto, ukudibanisa, ukudibanisa amacandelo ahlukeneyo, kunye novavanyo olungqongqo lokulawula umgangatho. Le nkqubo iqinisekisa ukuba imveliso yokugqibela iyisisombululo sokukhanyisa esikumgangatho ophezulu, esisebenzayo, nesihlala ixesha elide. Izibane ze-LED zihlala ziguquka ukuze zinikeze ukusebenza okuphuculweyo kunye nokusebenza, kwaye iinkqubo zabo zokuvelisa zidlala indima ebalulekileyo kwimpumelelo yabo kwishishini lokukhanyisa.
Oku ngasentla yinkqubo yokwenziwa kwezibane ze-LED. Ukuba unomdla kuyo, wamkelekile ukuba uqhagamshelane nomboneleli wesikhukula okhokelayo uTianxiang ukuyaFunda ngokugqithisileyo.
