Imininingwane etholwe ilambu elilodwa elimhlophe le-LED ebhodini eligugayo, isibonisi esobala nedatha etholakele lapho isibani esimhlophe se-LED siqoqelwe esikhanyisweni nakanjani kuyimali encane.
Ubukhulu balo mehluko buxhomeke kumapharamitha kagesi wokusebenza kwe-LED kanye nokwakheka kwe-luminaire, kanye nemvelo lapho i-luminaire isetshenziswa khona.
Okokuqala, hlobo luni lwelambu elimhlophe le-LED elikhethiwe.
Lokhu kubaluleke kakhulu, ikhwalithi yokukhanya okumhlophe kwe-LED kungashiwo ukuthi yinto ebaluleke kakhulu. Kwezinye izibonelo, i-chip efanayo ye-LED 14mil light segment chip isetshenziswa njengommeleli, futhi ukukhanya okumhlophe kwe-LED okufakwe yi-resin ejwayelekile ye-epoxy kanye ne-glue emhlophe kanye ne-package yeglue kukhanya endaweni engama-30 degree. Ngemuva kwamahora ayi-1000, idatha yokuncipha ukubola kokukhanya okungama-70%; uma ihlanganiswe ne-D-type-resistant-glue, endaweni efanayo yokuguga, ukubola kokukhanya kungama-45%; uma i-C-type glue ephansi ukumelana ifakiwe, endaweni efanayo yokuguga. Uma i-B-type glue enamafutha aphansi ifakiwe, endaweni efanayo yokuguga, ukubola okuncane kwezinkulungwane ezincane ngu -3%; uma i-glue esezingeni eliphansi yohlobo A, endaweni efanayo yokuguga, i-Dawn encane eyinkulungwane eyincithakalo iye ku- -6%.
Kungani izinqubo ezahlukahlukene zokupakisha ziholela umehluko omkhulu?
Esinye sezizathu eziyinhloko ukuthi ama-chip e-LED esaba ukushisa. Kwesinye isikhathi, ukushisa kudlula ngaphezu kwamadigri ayikhulu ngesikhathi esifushane, akunandaba, ukwesaba ukuthi kuzoba ngaphansi kokushisa okuphezulu isikhathi eside, kuyingozi enkulu kwi-chip ye-LED.
Ngokuvamile, ukuqhutshwa kokushisa kwe-epoxy resin ngokuvamile kuncane. Ngakho-ke, lapho i-chip ye-LED ikhanyisiwe, i-chip ye-LED ikhipha ukushisa, kanti i-resin ejwayelekile ye-epoxy inomkhawuko wokwenza izinto ezishisayo, ngakho-ke uma uvela ekukhanyeni okumhlophe kwe-LED Ngaphandle, izinga lokushisa lesiphathi se-LED lilinganiswa ngama-degree angama-45, kanti ukushisa okuphakathi nendawo kwe-chip ku-LED emhlophe kungadlula ama-degree angama-80. Indawo yokushisa ye-LED empeleni ngama-degree angama-80. Lapho-ke, lapho i-chip ye-LED isebenza lapho kushisa izinga lokuhlangana, ihlushwa kakhulu, okusheshisa ukuguga kwelambu elimhlophe le-LED.
Lapho i-chip ye-LED isebenza, ukushisa okuphakathi nendawo kukhiqiza ukushisa okuphezulu okungama-degree ayi-100, futhi ukuboniswa okusobala kungakhipha ngokushesha ukushisa ngepini lobakaki 98%, ngaleyo ndlela kunciphise ukulimala kokushisa. Ngakho-ke, lapho i-LED light light bracket light ingama-degree angama-60, izinga layo lokushisa le-chip centre lingaba ngama-degree angama-61 kuphela.
Kungabonakala kwimininingwane engenhla ukuthi isibani esimhlophe se-LED senqubo yokupakisha sikhethwe ukunquma ngqo isimo sokubola kokukhanya kwesibani se-LED.
