Isiphumo se-Infrared LED Amaso isibane kwi-LED Display

Impembelelo ye-infrared LED amaso isibane kumboniso LED 1. I-angle yokujonga: Umbono wesiboniso se-LED umisela imbono ye-infrared LED amaso isibane. Okwangoku, uninzi lwezikrini zokubonisa zangaphandle zisebenzisa umbono othe tye 100 °; Imbono ethe nkqo 50 °; I-ellipse LED, isikrini sokubonisa sangaphakathi si-120 nkqo °; Isiqwenga se-LED. Umboniso koohola bendlela ukhethwa ngokubanzi ukusuka kwi-30 ngenxa yobungcali bayo °I-LED ejikelezileyo yembono yanele. Umboniso kwizakhiwo eziphakamileyo zifuna iimbono eziphezulu ezithe nkqo. Umbono kunye nokukhanya kuyaphikisana, kwaye imbono enkulu ngokuqinisekileyo iya kunciphisa ukukhanya. Ukhetho lwembono kufuneka lumiselwe ngokwenjongo ethile. 2. Ukukhanya: Ukukhanya kwe-LED yinto ebalulekileyo ethatha isigqibo ekukhanyeni kwesikrini sokubonisa. Ukuphakama kokukhanya kwe-LED, ibhalansi enkulu yokusebenzisa yangoku, okulungileyo ukugcina ukusetyenziswa kwamandla kunye nokugcina i-LED izinzile. I-LED inexabiso le-angle eyahlukileyo. Ngokuqaqamba kwetshiphu, i-engile encinci, ikhanya ngakumbi i-LED, kodwa incinci i-engile yokujonga yesikrini sokubonisa. Ngokuqhelekileyo, i-LED ye-100-degree kufuneka ikhethwe ukuqinisekisa ukuba isikrini sokubonisa sanele. Kwizithuba ezahlukeneyo kunye nomboniso wombono owahlukileyo, indawo yokulinganisa kufuneka ifumaneke ekukhanyeni, i-angle kunye nexabiso. 3. Ubuchule obunye: Kuba umboniso wombala ogcweleyo wenziwa ngamashumi amawaka okanye namakhulu amawaka amaqela obomvu, oluhlaza, nobhlowu, iipikseli zenziwe ngeepixels. Ukungaphumeleli kwawo nawuphi na umbala we-LED kuya kuchaphazela umphumo obonakalayo weskrini sokubonisa. Ngokuqhelekileyo, ngokuhambelana namava oshishino, ilahleko esebenzayo ngaphambi kokuba isiboniso se-LED siqale ukuhlanganiswa kwiiyure ze-72 zokuthunyelwa kufuneka zibe ngaphantsi kwe-3% (ibhekisela ekungaphumeleli okubangelwa yi-infrared LED amaso ngokwawo). Ukuqonda ukukhanya kwezibane ze-infrared ze-LED, okokuqala, kufuneka siqonde ukuba (i) yingcamango yomzimba, iyunithi yiCD. Ubungakanani bokukhanya okukhuphayo bubonisa ukudityaniswa komzimba okhuphayo esithubeni. Kwimeko elula, kukubonisa ukuba ungakanani umthombo wokukhanya “Eqaqambileyo ”Undoqo Ukusebenza kwezibane zanamhlanje ze-infrared LED amaso zihlala zilinganisa oku kukhanya. Umzekelo, i-infrared LED bead yi-15000mcd, 1000mcd = 1cd, eyi-15CD. Ukuqaqamba kwee-LED kusetyenziswa yi-MCD endaweni ye-CD ngokuthe ngqo kuba iintsimbi zesibane se-infrared zangaphambili zine-luminescence ephantsi kwaye ukuqaqamba kumnyama kunokukhanya. Sebenzisa isibane sokukhanya ukubonisa iliso lesibane se-infrared “ukuqaqamba ”Nangona iyinjongo, kukwakho neziphene. Umzekelo, amaso amabini e-infrared isibane se-LED anexabiso elifanayo lokuqaqamba anomgangatho ophezulu wokuqaqamba. Ngoko ke, abathengi abafanele banikele ingqalelo kuphela kwixabiso lexabiso lokukhanya xa befumana ubuhlalu besibane se-infrared LED, kodwa banikele ingqalelo ekuthelekiseni indawo yokujonga. Ngaphantsi kweemeko ezifanayo, isisombululo esincinci, siphezulu ukukhanya kwiyunithi. Kungenjalo, kungenjalo. Ukongeza, kukho enye ipharamitha yokukhanya kwesibane se-infrared isibane sokukhanya: ukukhanya kwe-infrared LED beads (F), iyunithi yi-LM, kwaye sihlala sisebenzisa i-lumens ngesiTshayina. Umlinganiselo wokukhanya. Kumthombo wokukhanya, lo mlinganiso yinkcukacha enkulu ebonisa isixa esipheleleyo semithombo yokukhanya. Ilingana namandla optical. Okukhona i-optical flux yomthombo wokukhanya, kokukhona ukukhanya kubhengeza ukukhanya kunye nokomelela kokukhanya. Ngokumalunga nokukhanya kwezibane ze-infrared zesini esifanayo (ukukhanya kwemithombo yokukhanya kuqaliswe kuwo onke amacala kuwo onke amacala), F = 4 πI. Oko kukuthi, ukuba i-I yomthombo wokukhanya yi-1cd, ukukhanya okupheleleyo kukukhanya 4 πLM. Ukuba ufuna ukuqaqamba, akufuneki nje siphucule ukukhanya okukhanyayo, kodwa nokunyusa izinga le-agglomeration. Enyanisweni, kukunciphisa indawo ekhanyayo, ukuze sifumane ukuqina okukhulu.
