Izibani ze-LEDziyinketho yokukhanyisa edumile ngenxa yokusebenza kahle kwazo okuphezulu, impilo ende, nokukhanya okuyingqayizivele. Kodwa ingabe wake wazibuza ukuthi lezi zibani ezingavamile zenziwa kanjani? Kulesi sihloko, sizohlola inqubo yokukhiqiza izibani ze-LED kanye nezingxenye ezizenza zisebenze ngempumelelo.
Isinyathelo sokuqala sokudala i-floodlight ye-LED ukukhetha into efanele. Izinto eziyinhloko ezisetshenziswayo ama-LED ekhwalithi ephezulu, izingxenye ze-elekthronikhi, namasinki okushisa e-aluminium. I-chip ye-LED iyinhliziyo ye-floodlight futhi ngokuvamile yenziwe ngezinto ze-semiconductor ezifana ne-gallium arsenide noma i-gallium nitride. Lezi zinto zinquma umbala okhishwe yi-LED. Uma izinto sezitholakele, inqubo yokukhiqiza ingaqala.
Ama-chips e-LED afakwe ebhodini lesekethe, elaziwa nangokuthi i-PCB (ibhodi lesifunda eliphrintiwe). Ibhodi lisebenza njengomthombo wamandla wama-LED, lilawula lamanje ukuze ligcine izibani zisebenza kahle. Faka i-solder paste ebhodini bese ubeka i-chip ye-LED endaweni ekhethiwe. Umhlangano wonke ube usushiselwa ukuze uncibilikise unamathisele we-solder futhi ubambe i-chip endaweni. Le nqubo ibizwa ngokuthi i-reflow soldering.
Ingxenye elandelayo engukhiye ye-floodlight ye-LED i-optics. I-Optics isiza ukulawula indlela kanye nokusabalala kokukhanya okukhishwa ama-LED. Amalensi noma izibonisi zivame ukusetshenziswa njengezinto ezibonakalayo. Amalensi anesibopho sokuhlukanisa i-beam yokukhanya, kuyilapho izibuko zisiza ukuqondisa ukukhanya ezindaweni ezithile.
Ngemuva kokuthi umhlangano we-chip we-LED kanye ne-optics sekuqediwe, i-electronic circuitry ihlanganiswe ne-PCB. Lo mjikelezo wenza i-floodlight isebenze, ukuyivumela ukuthi ivule futhi ivale futhi ilawule ukukhanya. Ezinye izibani zezikhukhula ze-LED zihlanganisa izici ezengeziwe njengezinzwa ezinyakazayo noma amandla okulawula kude.
Ukuze uvimbele ukushisa ngokweqile, izibani zezikhukhula ze-LED zidinga amasinki okushisa. Amasinki okushisa avame ukwenziwa nge-aluminium ngenxa ye-thermal conductivity enhle kakhulu. Isiza ukuqeda ukushisa okudlulele okukhiqizwa ama-LED, iqinisekisa ukuphila kwawo isikhathi eside nokusebenza kahle. I-sink yokushisa ifakwe ngemuva kwe-PCB ngezikulufu noma unamathisele okushisa.
Lapho izingxenye ezihlukene sezihlanganisiwe futhi zahlanganiswa, izindlu ze-floodlight zengezwa. Icala alivikeli kuphela izingxenye zangaphakathi kodwa futhi lihlinzeka ngobuhle. Izivalo ngokuvamile zenziwe nge-aluminium, ipulasitiki, noma inhlanganisela yakho kokubili. Ukukhethwa kwezinto kuncike ezintweni ezinjengokuqina, isisindo, kanye nezindleko.
Ukuhlolwa kokulawula ikhwalithi okuphelele kuyadingeka ngaphambi kokuthi izibani ze-LED ezihlanganisiwe zilungele ukusetshenziswa. Lokhu kuhlola kuqinisekisa ukuthi i-floodlight ngayinye ihlangabezana nezindinganiso ezicacisiwe mayelana nokukhanya, ukusetshenziswa kwamandla, nokuqina. Izibani zibuye zihlolwe ezindaweni ezihlukahlukene, okuhlanganisa izinga lokushisa kanye nomswakama, ukuze kuqinisekiswe ukwethembeka kwazo ezimweni ezahlukene.
Isinyathelo sokugcina ohlelweni lokukhiqiza ukupakisha nokusabalalisa. I-LED Flood Lights ihlanganiswe ngokucophelela namalebula wokuthumela. Abe esesatshalaliswa kubathengisi noma ngokuqondile kubathengi, alungele ukufaka futhi anikeze ukukhanya okukhanyayo nokusebenza kahle kwezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa izinkundla zemidlalo, izindawo zokupaka, nezakhiwo.
Sekukonke, inqubo yokukhiqiza izibani zezikhukhula ze-LED ihlanganisa ukukhethwa ngokucophelela kwezinto, ukuhlanganisa, ukuhlanganiswa kwezingxenye ezihlukahlukene, nokuhlolwa kokulawula ikhwalithi okuqinile. Le nqubo iqinisekisa ukuthi umkhiqizo wokugcina uyisixazululo sokukhanyisa esisezingeni eliphezulu, esisebenza kahle futhi esihlala isikhathi eside. Izibani ze-LED zihlala zishintsha ukuze zinikeze ukusebenza okuthuthukisiwe nokusebenza, futhi izinqubo zabo zokukhiqiza zidlala indima ebalulekile empumelelweni yazo embonini yokukhanyisa.
Okungenhla inqubo yokukhiqiza ama-floodlights e-LED. Uma unentshisekelo kukho, wamukelekile ukuthintana nomhlinzeki we-led flood light u-Tianxiang ukuzeFunda kabanzi.
