Yiziphi Izizathu Ezithinta Ukubola Kokukhanya kwamamojula we-LED Point Light Source

Idatha etholwe yisibani esisodwa esimhlophe se-LED ebhodini lokuguga kanye nedatha etholwe lapho imojuli yomthombo wokukhanya wamachashazi e-LED ihlanganiswa ibe ukuguga kwesibani. Ubukhulu balo mehluko buncike kumingcele kagesi kanye nomklamo wezibani ngesikhathi somsebenzi 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 ye-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 lamamojula omthombo wokukhanya we-LED iphuzu. 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 kukhona amamojula wemithombo yokukhanya eyi-100 ye-LED ukuze kukhanye ngesikhathi esifanayo, isikhathi esiphakathi kwawo singu-11.4mm kuphela, khona-ke izinga lokushisa lobakaki lomthombo wokukhanya we-LED elizungeze inqwaba yesibani lingase lingeqi ama-degree angu-45, kodwa phakathi nendawo. yenqwaba yesibani Lezo mithombo yokukhanya ye-LED ingafinyelela 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. Nokho, uma imojula yomthombo wokukhanya wephoyinti le-LED iqhelelene ngaphezu kuka-25mm, khona-ke amakhalori abawadluliselayo ngeke aqongelele kangako. Ngalesi sikhathi, izinga lokushisa le-LED ngayinye ye-bead bracket kufanele libe ngaphansi kwama-degree angu-50, okuhambisana kakhulu ne-LED evamile evamile ye-LED. Sebenza. Uma imvelo yomsebenzi we-LED isendaweni ebanda kakhulu, izinga lokushisa elijwayelekile lonyaka wonke lingase libe cishe ama-degree angu-15 noma ngaphansi, khona-ke ku-LED, ubude bokuphila bude.
