Izinto ezithinta ikhwalithi nokubola kokukhanya kwelanga le-LED
Okokuqala, khetha ukuthi hlobo luni lwezibani zelanga ze-LED.
Lokhu kubaluleke kakhulu, ikhwalithi yezibani zelanga ze-LED kungathiwa yinto ebaluleke kakhulu. Ukunikeza izibonelo ezithile, i-chip yengxenye yokukhanya emhlophe efanayo eyi-14mil imelwe amalambu elanga e-LED ambozwe nge-epoxy resin primer evamile kanye nokunamatheliswa kokukhanya okumhlophe kanye ne-encapsulating glue.
Ukukhanya okukodwa endaweni engama-degree angu-30, amahora ayinkulungwane kamuva, Idatha yokunciphisa izinga lokulungisa elikhanyayo lama-70%; uma ihlanganiswe ne-D-type low-failure glue, ukukhanya okukhanyayo kungama-45% ngamahora ayinkulungwane ngaphansi kwendawo efanayo yokuguga; uma ihlanganiswe ne-C-type low-failure glue, ukubola okufanayo kokukhanya kwehora kungu-12%; uma i-glue ye-Class B yokwehluleka okuphansi ihlanganiswe, ngaphansi kwendawo efanayo yokuguga, ukubola kokukhanya kwamahora ayinkulungwane kungu-3%; uma i-glue ye-Class A low-failure, ngaphansi kwendawo efanayo yokuguga, ukubola kokukhanya kwamahora ayinkulungwane kungu-6%.
Okwesibili, izinga lokushisa elisebenzayo lamalambu elanga e-LED.
Ngokusho kwedatha yesibani esisodwa selanga se-LED lapho siguga uma isibani esisodwa selanga se-LED sisebenza, futhi izinga lokushisa elizungezile lingama-degree angu-30, khona-ke izinga lokushisa lobakaki lapho isibani esisodwa esimhlophe se-LED sisebenza ngeke sibe Ngaphezu kuka-45. amadigri. Ngalesi sikhathi, impilo yale LED izoba yinhle.
Uma kukhona izibani zelanga ze-LED eziyi-100 ezisebenza ngesikhathi esisodwa, futhi isikhathi phakathi kwazo singu-11.4mm kuphela, khona-ke izinga lokushisa likabakaki lamalambu elanga e-LED azungeze inqwaba angeke lidlule ama-degree angu-45, kodwa lawo ma-LED anamandla anamandla. izinga lokushisa eliphezulu elingase lifinyelele ku-65 degrees. Ngalesi sikhathi, ubuhlalu besibani se-LED buyisivivinyo. Khona-ke, izibani zelanga ze-LED ezihlangana phakathi nendawo ziyoba nokubola kokukhanya okusheshayo, kuyilapho izibani zelanga ze-LED ezizungeze inqwaba zizobola kancane kancane.
Noma kunjalo, wonke umuntu kufanele azi ukuthi i-LED yesaba ukushisa. Ukuphakama kwezinga lokushisa, impilo ye-LED ibe mfushane, izinga lokushisa liyancipha, impilo ye-LED ibe yinde. Izinga lokushisa elifanele le-LED liphakathi kuka-minus 5 no-zero degrees. Kodwa lokhu akunakwenzeka.
Ngakho-ke, ngemva kokuqonda imingcele efanelekile yokusebenza yobuhlalu bokukhanya kwelanga be-LED, sizama ngakho konke okusemandleni ethu ukuthuthukisa imisebenzi yokuqhuba ukushisa nokukhipha ukushisa lapho siklama izibani. Noma kunjalo, lapho izinga lokushisa liphansi, iba yinde impilo ye-LED.
Okwesithathu, imingcele kagesi esebenzayo yobuhlalu besibani se-LED iklanyelwe.
Ngokwemiphumela yokuhlola, ukwehla kwamandla okushayela kwelambu lelanga le-LED, kuncane ukushisa okukhiphayo, yiqiniso, kuyancipha ukukhanya. Ngokusho kocwaningo, ukuklanywa kwesifunda sokukhanyisa ukukhanya kwe-LED, ukushayela kwe-LED ngokuvamile ku-5-10mA kuphela; imikhiqizo enenani elikhulu lobuhlalu bezibani, njengokufinyelela ngaphezu kuka-500, noma ngaphezulu, okwamanje ukushayela ngokuvamile kuphela 10-15mA Nokho, ukushayela kwamanje kokukhanyisa kwesicelo se-LED okujwayelekile kungu-15-18mA kuphela, futhi abantu abambalwa abaklama okwamanje. ngaphezu kwe-20mA.
Imiphumela yokuhlola iphinde ibonise ukuthi ngaphansi kwamandla okushayela angu-14mA, futhi isembozo asikwazi ukungena emoyeni, izinga lokushisa lomoya ngaphakathi lifinyelela kuma-degree angu-71, umkhiqizo obolile kancane unokuncishiswa kokukhanya okuyiziro emahoreni ayi-1000, kanye no-3% ngo-2000. amahora. Lokhu kubonisa ukuthi ukusetshenziswa kwalezi zibani zelanga ze-LED ezibolile eziphansi sekufinyelele umkhawulo wazo endaweni enjalo, futhi umonakalo omkhulu kakhulu kuwo.
Ngenxa yokuthi ibhodi yokuguga yokuguga ayinakho umsebenzi wokushisa ukushisa, ukushisa okukhiqizwa yi-LED ngesikhathi sokusebenza akukwazi ukuqhutshwa ngaphandle. Lokhu kufakazelwa ngokuhlola. Izinga lokushisa lomoya ebhodini lokuguga lifinyelele izinga lokushisa eliphakeme lama-degree angu-101, futhi izinga lokushisa elingaphezulu lesembozo ebhodini lokuguga lingama-degree angu-53 kuphela, okuwumehluko wenqwaba yamadigri. Lokhu kubonisa ukuthi isembozo sepulasitiki esiklanyelwe asinawo umsebenzi wokuqhuba ukushisa kanye nokukhipha ukushisa.
Kodwa-ke, ngokujwayelekile, ukuklama kwesibani, umsebenzi wokushisa ukushisa kanye nokukhishwa kokushisa kubhekwa. Ngakho-ke, ngokufingqa, ukuklama kwemingcele kagesi esebenzayo ye-bead yesibani se-LED kufanele kusekelwe esimweni sangempela.
Uma umsebenzi wokushisa nokushisa kwesibani muhle kakhulu, akunandaba ukuthi ukushayela kwesibani selanga se-LED kwanda kancane, ngoba ubuhlalu besibani se-LED busebenza Ukushisa kungathunyelwa ngaphandle ngokushesha, ngaphandle ukulimaza i-LED, okuwukunakekelwa okungcono kakhulu kwe-LED. Ngokuphambene nalokho, uma umsebenzi wokushisa nokushisa kwesibani unjalo-ngakho, kungcono ukuklama isifunda sibe sincane futhi sivumele ukukhulula ukushisa okuncane.
