Yiziphi Izinto Ezizothinta Ikhwalithi Yokubola Kokukhanya Yemojula Yomthombo Wokukhanya We-LED

Idatha etholwe yisibani esisodwa esimhlophe se-LED ebhodini eliguga, kanye nedatha etholwe lapho ihlanganiswa izibani ezimhlophe ze-LED zibe ukuguga kwesibani nakanjani iphumile. Ubukhulu balo mehluko buncike kumingcele kagesi kanye nomklamo wezibani ngesikhathi semodyuli yomthombo wokukhanya we-LED, kanye nemvelo esetshenziswa izibani. Okokuqala, hlobo luni lobuhlalu besibani se-LED olukhethayo. Lokhu kubaluleke kakhulu. Izinga lobuhlalu belambu le-LED lingashiwo njengento ebaluleke kakhulu. Isibonelo, okufanayo kuvezwa i-chip ye-chip ye-chip 14mil, kanye nobuhlalu besibani se-LED obumbozwe inhlaka ephansi neglue emhlophe kanye neglue yokupakisha eyenziwe nge-epoxy resin evamile, ekhanyisa eyodwa endaweni engama-30. amadigri. Ngemva kwezinkulungwane zamahora, idatha encishisiwe ingu-70% wokubola kokubona; uma i-D yohlobo lwe-D ephansi-i-glue ebolile ihlanganiswe, endaweni efanayo yokuguga, ukubola kokukhanya kwehora le-1,000 ku-45%; , ukubola kokukhanya kwamahora angu-1 000 kungu-12%; uma isigaba B sihlanganiswe ku-glue eyancipha kancane, endaweni efanayo yokuguga, izinkulungwane zamahora okubola kokukhanya kwe--3%; uma i-Class A iyiglue eyehla kancane, endaweni efanayo yokuguga, izinkulungwane zamahora okukhanya endaweni efanayo yokuguga, izinkulungwane zamahora okukhanya endaweni efanayo yokuguga, izinkulungwane zamahora okukhanya endaweni efanayo yokuguga, izinkulungwane amahora okukhanya endaweni efanayo yokuguga, izinkulungwane zamahora okukhanya kwezinkulungwane zamahora okukhanya. Uyini umehluko phakathi kwenqubo yokupakisha ehlukile? Isizathu esiyinhloko ukuthi i-chip module yomthombo wokukhanya we-LED yesaba ukushisa. Ngezinye izikhathi ukushisa okungaphezu kwama-degrees angu-100 ngesikhathi esifushane, akuqinile, ngesaba ukuthi kuzoba ukushisa okuphezulu isikhathi eside, okuwumonakalo omkhulu ku-chip ye-LED. Ngokuvamile, ukuqhutshwa kokushisa kwama-epoxy resins kuncane. Ngakho-ke, lapho ama-chips e-LED akhanyisiwe, ama-chips e-LED kufanele akhiphe ukushisa, futhi ukuqhutshwa kokushisa okujwayelekile kwe-epoxy resin kunqunyelwe. Lapho izinga lokushisa lobakaki we-LED lingu-45 degrees, izinga lokushisa eliphakathi nendawo le-chip ekukhanyeni okumhlophe kwe-LED lingase lidlule ama-degree angu-80. I-node yokushisa ye-LED empeleni ingu-80 degrees, ngakho-ke uma i-chip ye-LED isebenza ekushiseni kwezinga lokushisa, ihlupheka kakhulu, okusheshisa ukuguga kwemithombo yokukhanya ye-LED. Lapho i-chip ye-LED isebenza, izinga lokushisa eliphakathi likhiqiza izinga lokushisa eliphakeme lama-degree angu-100. Ingasebenzisa ngokushesha iphinikhodi yokuma ekushiseni ukunciphisa ukushisa, ngaleyo ndlela inciphise umonakalo kuyo. Ngakho-ke, lapho izinga lokushisa lobuhlalu belambu le-LED lingama-degree angama-60, izinga lokushisa lesikhungo sayo se-chip lingase libe ngama-degree angama-61 nje. Njengoba kubonakala kudatha engenhla, ubuhlalu besibani se-LED abakhetha ukuthi yiluphi uhlobo lwenqubo yokupakisha ekhethiwe, futhi isinqumo sokukhanya sezibani ze-LED sinquma ngokuqondile isinqumo sokukhanya kwezibani ze-LED. Okwesibili, izinga lokushisa lendawo yokusebenza lemoduli yomthombo wokukhanya we-LED. Ngokusho kwedatha yomthombo owodwa wokukhanya we-LED, uma umthombo wokukhanya we-LED unomsebenzi owodwa wokukhanyisa, futhi ngesikhathi esifanayo, izinga lokushisa elizungezile lingama-degree angu-30, izinga lokushisa lobakaki lomthombo owodwa wokukhanya we-LED alidluli. Ama-degree angama-45 ngesikhathi sokusebenza kwama-degree angama-45. Ngalesi sikhathi, impilo yale LED izoba yinhle. Uma kunemithombo yokukhanya ye-LED eyi-100 emsebenzini ngesikhathi esifanayo, isikhawu phakathi kwayo ngu-11.4mm kuphela, khona-ke izinga lokushisa likabakaki lomthombo wokukhanya we-LED elizungeze inqwaba yesibani lingase lingeqi ama-degree angu-45, kodwa lawo ma-LED aphakathi nendawo. izinqwaba zezibani ngeke Umthombo wokukhanya ungafinyelela izinga lokushisa eliphakeme lama-65 degrees. Ngalesi sikhathi, umthombo wokukhanya we-LED uwukuhlola. Khona-ke, leyo mithombo yokukhanya ye-LED eqoqwe phakathi izoshesha ngokomqondo, futhi imithombo yokukhanya ye-LED ezungeze inqwaba yesibani izohamba kancane. Kodwa uma ubuhlalu besibani se-LED buhlukene ngokungaphezu kuka-25mm, khona-ke amakhalori abawadluliselayo ngeke aqongelele kangako. Ngalesi sikhathi, izinga lokushisa le-LED ngayinye yobuhlalu kufanele libe ngaphansi kwama-degree angu-50, okuhambisana kakhulu nomsebenzi ojwayelekile we-LED. Uma indawo yemojula yomthombo wokukhanya we-LED isendaweni ebanda kakhulu, izinga lokushisa elimaphakathi lonyaka wonke lingase libe cishe kuphela amadigri ayi-15 noma ngaphansi, okuyinde kuma-LED.
