A Iphaneli ye-LED ekhanyiswe ngasemvayenziwe ngoluhlu lwee-LED ezifakwe kwipleyiti ethe tye ekhazimle ngokuthe nkqo ezantsi nge-diffuser ukuya kwisithuba ukuze sikhanyiselwe.Iiphaneli ezikhanyisa ngasemva ngamanye amaxesha zikwabizwa ngokuba ziipaneli ezikhanyisa ngokuthe ngqo.

An Iphaneli ye-LED ekhanyayoyenziwe ngomqolo wee-LED ezincanyathiselwe kwisakhelo (okanye umjikelezo) wephaneli, ikhanya ngokuthe tye kwipleyiti yokukhanya (LGP).I-LGP iqondisa ukukhanya ezantsi, nge-diffuser kwisithuba esingezantsi.Iipaneli ezikhanyiswe ngomphetho ngamanye amaxesha zikwabizwa ngokuba ziipaneli ezikhanyayo ezisecaleni.

Zikhanyiswe ngomphetho okanye zikhanyiswe ngasemvaIipaneli ze-LEDngcono?

Zomibini ziyilo zineenzuzo kunye neengxaki.Iiphaneli ezilayitiweyo zezokuqala ukuveliswa ngobuninzi.

Uyilo olukhanyiswe emphethweni lukhethwe ngenxa yezizathu ezininzi:

• I-light-guide plate (LGP) yindlela esebenzayo nelula yokusasaza ukukhanya, ukuphepha umngcipheko weendawo ezikhanyayo.
• Ubukho be-LGP kuthetha ukuba i-diffuser ayiloxanduva lokusasaza ukukhanya ngokulinganayo ukuze imathiriyeli enexabiso eliphantsi isetyenziswe, ngaphandle kokuba ayityheli ngenxa yobudala.
• Akukho zielensi zifunwayo kwaye uyilo olukhanyisiweyo lusebenza kakuhle ngeendidi ezahlukeneyo zee-engile ze-LED.
• Ubushushu obuvela kwiitshiphusi ze-LED buchithwa ngesakhelo, ngoko ke umva unokuba nobunzima obulula kwaye awuzukutshisa, ngoko ke umqhubi unokubekwa apha ukuba uyafuneka.

Ekuhambeni kwexesha iintsilelo zale ndlela ziye zabonakala.Eyona imathiriyeli ye-LGP yi-acrylic (PMMA), kodwa oku kunokuba kubiza kakhulu, ngoko ke yayisoloko isetyenziswa i-polystyrene (PS) engabizi kakhulu.Ukuba ayidityaniswanga nezongezo zozinziso ze-UV, ii-PS LGPs zijika zibetyheli ngokuhamba kwexesha ukuze ukusebenza kakuhle kuwele, ukuphuma kokukhanya kujike kube tyheli obumnyama kwaye umbindi wephaneli uba mnyama ngelixa iperiphery ihlala iqaqambile.

Ukongeza, ezinye izibonisi zangasemva (jonga umzobo ongasentla) zihluthwe iminyaka yobudala ithoba ngakumbi ukusebenza kweepaneli ze-LED ezikhanyiswe kwangoko.

Inkqubela phambili yobugcisa ngoku ivumele isizukulwana esitsha seepaneli ze-LED ezikhanyiswe ngasemva ukuba zaziswe.Ezi zihlala zisebenza kakuhle kunye neendleko zeyunithi eziphantsi kuneepaneli ze-LED zangaphambili.

• Ii-LED ziye zasebenza ngakumbi, ngoko ke inzuzo ye-thermal ekhoyo kuyilo lwe-side-lit iye yabaluleka kangako.Uyilo olukhanyiswe ngasemva alusekho shushu kangangokuba umqhubi akanakubekwa ngasemva.
• Iilensi zifikelele kwixabiso eliphantsi ukuvelisa kwaye izinto zokuncamathelisa zanamhlanje zithetha ukuba zinokuqiniselwa ngokukhuselekileyo kwi-LED nganye ukwenza usasazo olukhanyayo ngaphandle komngcipheko wokuba ziya kuwa - ukusilela kwezinye iipaneli zangaphambili nezibanexabiso eliphantsi.
• I-Micro-prismatic diffusers ziye zaxhaphaka, zingabizi kwaye zisebenza ngakumbi, ngoko ke isenzo esiphindwe kabini se-LGP / indibaniselwano ye-diffuser ayisafuneki.
• Ukupheliswa kwe-LGP kwi-back-lit designs kuthetha ukuba ukonga amandla okunokubakho kukhulu kunoyilo olukhanyayo, ukuba zonke ezinye izinto ziyalingana.

Imarike yokukhanyisa ngoku yamkela iiphaneli ezikhanyiswe ngasemva ngokulula njengeepaneli ezikhanyisa emphethweni kwaye, ngenxa yokuba iiphaneli ezikhanyisa ngasemva azifuni i-LGP okanye isibonisi sangasemva, zihlala zilelona xabiso liphantsi kunye neyona ipaneli ye-LED esebenzayo ekhoyo.

Ziziphi iingxaki ngexabiso eliphantsiiipaneli ze-LED ezikhanyiswe ngasemva?

Nantsi into ekufuneka uyijonge.

• Zimbalwa kakhulu ii-LED ezisetyenziswayo.Ii-LED ezimbalwa kakhulu (ngokuqhelekileyo i-36 okanye ngaphantsi) zithetha ukuba kufuneka ziqhutywe kumbane ophezulu ukuvelisa ukukhanya okufunekayo.Xa kuthelekiswa noyilo olusebenzisa ii-LED ezininzi, oku kungasebenzi kakuhle (ii-LED zisebenza ngokufanelekileyo kunye nemisinga ye-low drive), ivelisa ubushushu obuninzi, inciphisa ubomi bee-LED kwaye ikhawuleza ukuhla kwe-lumen.
• Imizimba yeplastiki.Iipaneli ezingcono ezikhanyisa ngasemva zisebenzisa umzimba wesinyithi.Oku kusebenza ngakumbi njengendawo yokutshisa ubushushu kunomzimba weplastiki (ungabizi kakhulu).Ii-LED zivelisa ubushushu obuthile kwaye oku kufuneka kucinywe ukuba ubomi babo abunakuba bufutshane ngakumbi.
• Ukuhanjiswa kokukhanya akudlulanga.Kwiphaneli ekhanyiswe kakuhle ngasemva i-LED nganye inelensi nganye kwaye iilensi ziyilelwe ukuze isibane esisuka kwi-LED nganye sigqithe isibane esivela kubamelwane.Oku kuya kuvelisa ifuthe elikhanyayo kunye nokomelela kwimeko apho i-LED enye isilela.Uyilo olulambathayo lwelensi kunye nenani eliphantsi lee-LED kusenokwenzeka ukuba zehlise ukuhlangana phakathi kwee-LED kwaye zonyuse umngcipheko wamabala aqaqambileyo namnyama ngaphambili kwindawo efanelekileyo.
• Ngaba iilensi zimiliselwe ngokuqinileyo kwindawo?Lixesha kuphela eliya kuxela, kodwa umngcipheko kukuba ubushushu obuveliswa zii-LEDs, zidityaniswe ne-adhesive enexabiso eliphantsi esetyenziswa kakubi, iya kubangela ukuba iilensi ziwe.Isiphumo siya kuba kukusasazeka kokukhanya okungalinganiyo kunye nokuqaqamba okunokwenzeka.
• Umqhubi owakhelwe ngaphakathi.Abavelisi banokugcina imali ngokwakha umqhubi emzimbeni, kodwa oku kunemiqobo emininzi.Ayinakutshintshwa xa kukho ingxaki kwaye akusayi kubakho luzizi okanye ukhetho olungxamisekileyo.Yindlela engaguquguqukiyo kakhulu.
• Jonga iikona zesakhelo.Kwiipaneli zexabiso eliphantsi kuya kubonakala ukudibanisa okungathandekiyo.

UGR <19 ngeiipaneli ze-LED ezikhanyiswe ngasemva kunye nezikhanyisa emphethweni.

Zombini ziyilo zinokuthi, ngeqweqwe langaphambili lasekunene, zivelise ukusebenza kakuhle kwe-UGR.Ukuthelekisa iimpawu ezahlukeneyo kunye neemodeli jonga iitafile ze-UGR eziyinxalenye yedatha yefotometric ekufuneka ifumaneke kubo bonke abavelisi abathembekileyo.
