Izibani zomgwaqo ze-LEDziye zathandwa kakhulu eminyakeni yamuva njengoba amadolobha nomasipala befuna izindlela zokonga amandla nokunciphisa ukushaqeka kwekhabhoni. Lezi zixazululo zokukhanyisa zesimanje zinikeza izinzuzo eziningi, okuhlanganisa ukuqina, impilo ende, kanye nokusetshenziswa kwamandla okuphumelelayo. Enhliziyweni yazo zonke izibani zasemgwaqweni ze-LED kukhona ikhanda lezibani zasemgwaqweni ze-LED, eliqukethe izingxenye ezibalulekile ezenza lezi zibani zisebenze kahle.
Ngakho-ke, yini engaphakathi kwekhanda lesibani sesitaladi se-LED? Ake sibheke ngokuningiliziwe.
1. I-chip ye-LED
Ingqikithi yekhanda lesibani sesitaladi se-LED yi-chip ye-LED, okuyingxenye ekhipha ukukhanya kwesibani. Lawa ma-chip ngokuvamile enziwa ngezinto ezifana ne-gallium nitride futhi afakwe ku-substrate yensimbi. Uma kusetshenziswa ugesi, i-chip ye-LED ikhipha ukukhanya, okunikeza ukukhanya okudingekayo ekukhanyeni komgwaqo.
Ama-chip e-LED akhethwe ngenxa yokusebenza kwawo kahle kanye nokuphila isikhathi eside, okwenza abe mahle kakhulu ekusetshenzisweni kokukhanya kwangaphandle. Ngaphezu kwalokho, ama-chip e-LED atholakala emazingeni okushisa ahlukahlukene emibala, okuvumela omasipala ukuthi bakhethe umbala ofanele wokukhanya emigwaqweni yabo yedolobha.
2. Irediyetha
Njengoba ama-LED chips ekhiqiza ukukhanya ngokuguqula amandla kagesi abe ama-photon, akhiqiza nokushisa okukhulu. Ukuze kuvinjelwe i-LED chip ekushiseni ngokweqile futhi kuqinisekiswe ukuthi ihlala isikhathi eside, amakhanda ezibani zasemgwaqweni ze-LED afakwe ama-radiator. Lawa ma-heat sink aklanyelwe ukuqeda ukushisa okukhiqizwa ama-LED chips, ukugcina izinto zipholile futhi kuvimbele ukulimala kwezingxenye.
Izinki zokushisa zivame ukwenziwa nge-aluminium noma ithusi ukuze kwandiswe indawo engaphezulu etholakalayo yokushabalalisa ukushisa, okuvumela ukuphathwa kahle kokushisa ngaphakathi kwekhanda lokukhanya komgwaqo le-LED.
3. Umshayeli
Umshayeli ungenye ingxenye ebalulekile ngaphakathi kwekhanda lokukhanya komgwaqo le-LED. Njengoba kunjalo ngama-ballast ezibanini zokukhanya zendabuko, abashayeli balawula ukugeleza kwamanje kuma-chip e-LED, beqinisekisa ukuthi bathola i-voltage kanye nomsinga ofanele ukuze basebenze kahle.
Amashayeli e-LED nawo adlala indima ekufiphazeni nasekulawuleni ukuphuma kwezibani zasemgwaqweni. Izibani eziningi zasemgwaqweni ze-LED zanamuhla zifakwe amashayeli angahlelwa avumela ukulawulwa kokukhanya okuguquguqukayo, okuvumela omasipala ukuthi balungise ukukhanya kwezibani ngokusekelwe ezidingweni ezithile nesikhathi sosuku.
4. Ama-Optics
Ukuze kusatshalaliswe ukukhanya ngokulinganayo nangokuphumelelayo emgwaqweni, amakhanda ezibani zasemgwaqweni ze-LED afakwe ama-optics. Lezi zingxenye zisiza ekwakheni nasekuqondiseni ukukhanya okukhishwa ama-LED chips, zinciphise ukukhanya okukhanyayo kanye nokungcola kokukhanya ngenkathi zikhulisa ukubonakala kanye nokumbozwa.
Ama-reflector, amalensi, kanye nama-diffuser avame ukusetshenziswa kuma-LED streetlight optics ukuvumela ukulawulwa okunembile kwamaphethini okusabalalisa ukukhanya. Ngokwenza ngcono ukusatshalaliswa kokukhanya, izibani zasemgwaqweni ze-LED zingakhanyisa umgwaqo ngenkathi zinciphisa imfucuza yamandla kanye nokuchitheka kokukhanya.
5. Ukufakwa nokufakwa
Indlu yekhanda lesibani sesitaladi se-LED isebenza njengendlu yokuvikela yazo zonke izingxenye zangaphakathi. Ngokuvamile yenziwe ngezinto eziqinile njenge-die-cast noma i-aluminium ekhishwe ngaphandle, inikeza isivikelo ezintweni zezulu futhi igcina izingxenye zangaphakathi ziphephile ezintweni zemvelo ezifana nomswakama, uthuli, kanye namazinga okushisa aphezulu.
Ngaphezu kwalokho, indlu inomsebenzi wokufaka ikhanda lesibani sesitaladi se-LED esigxotsheni noma kwesinye isakhiwo sokusekela. Lokhu kuvumela ukufakwa okulula futhi kuqinisekisa ukuthi i-factory ibekwe kahle ukuze kukhanye kahle emgwaqweni.
Ngamafuphi, amakhanda okukhanya komgwaqo e-LED aqukethe izinto eziningi ezibalulekile ezisebenza ndawonye ukuhlinzeka ngokukhanya okusebenzayo, okuthembekile, nokunembile emigwaqweni yasemadolobheni nasemigwaqweni. Ngokufaka ama-LED chips, ama-heat sink, abashayeli, ama-optics, kanye nama-housing, amakhanda okukhanya komgwaqo e-LED enza omasipala bakwazi ukuzuza ezinzuzweni eziningi zokukhanya kwe-LED, okuhlanganisa ukonga amandla, ukugcinwa okuncishisiwe, kanye nokubonakala okuthuthukisiwe. Njengoba amadolobha eqhubeka nokusebenzisa izibani zomgwaqo ze-LED, ukuthuthukiswa kwemiklamo yamakhanda okukhanya komgwaqo e-LED ethuthukisiwe kuzodlala indima ebalulekile ekwandiseni izinzuzo zalesi sixazululo sokukhanyisa esisha.
Uma unesifiso sokukhanyisa ngaphandle, wamukelekile ukuxhumana nomkhiqizi wezibani zasemgwaqweni uTIANXIANG ku-thola ikhotheshini.
