Izibani ze-LEDziyizinketho zokukhanyisa ezidumile ngenxa yokusebenza kahle kwamandla azo, ukuphila isikhathi eside, kanye nokukhanya okumangalisayo. Kodwa wake wazibuza ukuthi lezi zibani ezingavamile zenziwa kanjani? Kulesi sihloko, sizohlola inqubo yokukhiqiza izibani ze-LED kanye nezingxenye ezenza zisebenze kahle.
Isinyathelo sokuqala ekudaleni isibani se-LED ukukhetha izinto ezifanele. Izinto eziyinhloko ezisetshenziswayo ama-LED asezingeni eliphezulu, izingxenye ze-elekthronikhi, kanye nezitsha zokushisa ze-aluminium. I-chip ye-LED iyinhliziyo yesibani se-floodlight futhi imvamisa yenziwe ngezinto ze-semiconductor ezifana ne-gallium arsenide noma i-gallium nitride. Lezi zinto zinquma umbala okhishwa yi-LED. Uma izinto sezitholiwe, inqubo yokukhiqiza ingaqala.
Ama-chip e-LED afakwe ebhodini lesifunda, elaziwa nangokuthi i-PCB (ibhodi lesifunda eliphrintiwe). Ibhodi lisebenza njengomthombo wamandla wama-LED, lilawula ugesi ukuze kugcinwe izibani zisebenza kahle. Faka i-solder paste ebhodini bese ubeka i-chip ye-LED endaweni ekhethiwe. Yonke inhlangano iyashiswa ukuze kuncibilikiswe i-solder paste bese ibamba i-chip endaweni yayo. Le nqubo ibizwa ngokuthi i-reflow soldering.
Ingxenye elandelayo ebalulekile yesibani se-LED yi-optics. Ama-optics asiza ukulawula indlela kanye nokusabalala kokukhanya okukhishwa ama-LED. Amalensi noma izibonisi zivame ukusetshenziswa njengezinto ezibonakalayo. Amalensi anesibopho sokushintshashintsha ukukhanya, kuyilapho izibuko zisiza ukuqondisa ukukhanya ngezindlela ezithile.
Ngemva kokuhlanganiswa kwe-chip ye-LED kanye ne-optics sekuqediwe, i-electronic circuitry ifakwa kwi-PCB. Le circuit yenza i-floodlight isebenze, ivumela ukuthi ivule futhi icime futhi ilawule ukukhanya. Ezinye izibani ze-LED flood zifaka nezici ezengeziwe njengezinzwa zokunyakaza noma amakhono okulawula kude.
Ukuze kuvinjelwe ukushisa ngokweqile, izibani ze-LED ezikhukhula zidinga ama-heat sink. Ama-heat sink avame ukwenziwa nge-aluminium ngenxa yokushisa kwawo okuhle kakhulu. Kuyasiza ekuqedeni ukushisa okweqile okukhiqizwa ama-LED, okuqinisekisa ukuthi ahlala isikhathi eside futhi asebenza kahle. I-heat sink ifakwe ngemuva kwe-PCB ngezikulufo noma i-thermal paste.
Uma izingxenye ezahlukene sezihlanganisiwe futhi zahlanganiswa, kwanezelwa izindlu zezibani zokukhanyisa. Ikesi alivikeli nje kuphela izingxenye zangaphakathi kodwa futhi linikeza ubuhle. Izivalo zivame ukwenziwa nge-aluminium, ipulasitiki, noma inhlanganisela yakho kokubili. Ukukhethwa kwezinto kuncike ezintweni ezifana nokuqina, isisindo, kanye nezindleko.
Kudingeka ukuhlolwa kokulawula ikhwalithi okuphelele ngaphambi kokuba izibani ze-LED ezihlanganisiwe zilungele ukusetshenziswa. Lokhu kuhlolwa kuqinisekisa ukuthi isibani ngasinye sihlangabezana nezindinganiso ezithile maqondana nokukhanya, ukusetshenziswa kwamandla, kanye nokuqina. Izibani ziphinde zihlolwe ezindaweni ezahlukene, okuhlanganisa izinga lokushisa kanye nomswakama, ukuqinisekisa ukuthembeka kwazo ezimweni ezahlukene.
Isinyathelo sokugcina enkambisweni yokukhiqiza ukupakisha nokusabalalisa. Izibani ze-LED Flood zipakishwa ngokucophelela ngamalebula okuthumela. Bese zisatshalaliswa kubathengisi noma ngqo kubathengi, zilungele ukufakwa futhi zinikeze ukukhanya okukhanyayo nokusebenza kahle kwezinhlelo ezahlukene zokusebenza, okuhlanganisa izinkundla zemidlalo, izindawo zokupaka kanye nezakhiwo.
Sekukonke, inqubo yokukhiqiza izibani ze-LED ihilela ukukhetha ngokucophelela izinto zokwakha, ukuhlanganiswa, ukuhlanganiswa kwezingxenye ezahlukahlukene, kanye nokuhlolwa okuqinile kokulawula ikhwalithi. Le nqubo iqinisekisa ukuthi umkhiqizo wokugcina uyisisombululo sokukhanyisa sekhwalithi ephezulu, esisebenzayo, nesihlala isikhathi eside. Izibani ze-LED zihlala zishintsha ukuze zinikeze ukusebenza okuthuthukisiwe kanye nokusebenza, futhi izinqubo zazo zokukhiqiza zidlala indima ebalulekile empumelelweni yazo embonini yokukhanyisa.
Lokhu okungenhla inqubo yokukhiqiza izibani ze-LED. Uma unentshisekelo kukho, wamukelekile ukuxhumana nomhlinzeki wezibani ze-LED uTianxiang ku-Funda kabanzi.
