Izikhumba ezikhokelweyoNgaba ukhetho olukhanyisiweyo oludumileyo ngenxa yokusebenza kwabo amandla aphezulu, ubomi obude, kunye nokuqaqamba okhethekileyo. Kodwa ukhe wazibuza ukuba zenziwe njani izibane ezingaqhelekanga? Kweli nqaku, siza kuhlolisisa inkqubo yokwenziwa kweendawo zokwenza izikhokheli kunye nezinto ezenza ukuba zisebenze kakuhle.
Inyathelo lokuqala lokudala isibane se-LED sikhetha izinto ezifanelekileyo. Ezona zinto ziphambili zisetyenzisiweyo zii-LEDS ezisemgangathweni eziphezulu, izinto ze-elektroniki, kunye ne-aluminium switts. I-chip ye-LED yintliziyo yesibane sobunzi kwaye ihlala yenziwe ngezinto ze-semiconductor ezifana ne-gemaium arsenide okanye i-gelium nitride. Ezi zixhobo zimisela umbala okhutshwe yi-LED. Nje ukuba kufunyenwe izixhobo, inkqubo yokuphuhlisa iqalile.
Iitshipsi ze-LED zixhonywe kwibhodi yesekethe, ekwabizwa ngokuba yi-PCB (iBhodi yeSiphako eprintiweyo). Ibhodi isebenza njengomthombo wamandla we-LED, elawula okwangoku ukugcina izibane zisebenza ngokufanelekileyo. Faka isicelo i-Therter Cola i-Conta kwiBhodi kwaye ubeke i-chip ye-LED kwisikhundla esichongiweyo. Indibano iphela ishushu inyibilike ukuba inyibilike irhwebi kwaye ibambe i-chip endaweni. Le nkqubo ibizwa ngokuba bathengisa ngokukhawuleza.
Icandelo eliyintloko elilandelayo lesibane se-LED sisibane seenyawo. I-Optics inceda ukulawula indlela kunye nokusasazeka kokukhanya okukhutshwe zii-LEDS. Iilensi okanye iziboniso zihlala zisetyenziswa njengezinto ezibonakalayo. Iilensi zinoxanduva lokuqalisa i-beam yokukhanya, ngelixa izibuko zinceda ngokubhekisa ukukhanya kwendlela ethile.
Emva kokuba intlanganiso ye-Chip ye-LED kwaye igqityiwe, i-elektroniki idityaniswe kwi-PCB. Esi siphaluka senza umsebenzi wezikhukula, awuvumela ukuba iqhubeke kwaye icime kwaye ilawule ukukhanya. Ezinye izibane ze-LED ziquka izinto ezongezelelweyo ezinjengeenzwa zentshukumo okanye amandla okulawula kude.
Ukuthintela ukugqithisa, izibane ezikhokelwa zizibane zifuna ukutshisa ubushushu. I-shart swinks zihlala zenziwa nge-aluminium ngenxa yokuqhutywa kwayo okugqibeleleyo. Kuyanceda ukwahlula ubushushu obugqithisileyo obuveliswe zii-LEDs, ukuqinisekisa ubumnene kunye nokusebenza kakuhle. Ubushushu bubekwe ngasemva kwe-PCB ngesikrini okanye i-thermal pastes.
Nje ukuba izinto ezahlukeneyo zahlanganisana kwaye zidityaniswe, zongezwa izindlu zemikhukula. Ityala alikhuseli kuphela izinto zangaphakathi kodwa likwabonelela ubuhle. Iindawo ezivaliweyo zihlala zenziwa nge-aluminium, iplastiki, okanye indibaniselwano yezi zinto zimbini. Ukukhethwa kwezinto kuxhomekeke kwizinto ezifana nokuqina, ubunzima, kunye neendleko.
Uvavanyo lolawulo olusemgangathweni luyafuneka ngaphambi kokuba kudityaniswe izikhukula ezihlanganisiweyo zokwenza. Ezi mvavanyo ziqinisekisa ukuba isibane ngasinye semizila sihlangabezana nemigangatho echaziweyo ngokubhekisele ekuqaqambekeni, ukusetyenziswa kwamandla, kunye nokuqina. Izibane zivavanywa kwiimeko ezahlukeneyo, kubandakanya ubushushu kunye nokufuma, ukuqinisekisa ukuthembeka kwabo kwiimeko ezahlukeneyo.
Inyathelo lokugqibela kwinkqubo yokwenziwa upakishe kunye nokuhanjiswa. Izibane ze-LED ze-LED zifakwe ngononophelo kwiileyibhile zokuhambisa. Zisasazwe ke kubathengisi okanye ngokuthe ngqo kubathengi, zikulungele ukufaka nokubonelela ngesibane esikhanyayo nesifanelekileyo sokukhanyisa ezahlukeneyo, kubandakanya amabala emidlalo, kunye nezakhiwo.
Konke konke, inkqubo yokwenziwa kwezikhukula ezikhokelwayo ibandakanya ukukhetha ngononophelo kwezinto, indibano, ukudityaniswa kwezinto ezahlukeneyo, kunye novavanyo lokulawula umgangatho ophantsi. Le nkqubo iqinisekisa ukuba imveliso yokugqibela inomgangatho ophezulu, ofanelekileyo, oqinisekileyo wokukhanya. Izizwe ezikhokelwa zizikhukula zihlala zinikezela ukusebenza okuphuculweyo kunye nezenzo zemveliso zawo zidlala indima ebalulekileyo kwimpumelelo yabo kumzi-mveliso wokukhanyisa.
Oku kungasentla yinkqubo yokwenziwa kwezikhukula ezikhokelayo. Ukuba unomdla kuyo, wamkelekile ukunxibelelana nomthengisi wokukhanya we-tianxiang ukuyaFunda ngokugqithisileyo.
