A Iphaneli ye-LED ekhanyiswe ngemuvayenziwe ngama-LED ahlukahlukene afakwe epuleti elivundlile elikhanya liqonde phansi nge-diffuser lingene esikhaleni esizokhanyiswa.Amaphaneli akhanyisa emuva kwesinye isikhathi aziwa nangokuthi amaphaneli anokukhanya okuqondile.

An Iphaneli ye-LED ekhanyayoyenziwe ngomugqa wama-LED anamathiselwe kuhlaka (noma umjikelezo) wephaneli, acwebezela ngokuvundlile abe yipuleti lomhlahlandlela wokukhanya (LGP).I-LGP iqondisa ukukhanya kuye phansi, nge-diffuser kusikhala esingezansi.Amaphaneli anokukhanya onqenqemeni kwesinye isikhathi aziwa nangokuthi amaphaneli anokhanyi oluseceleni.

Zikhanyiswe onqenqemeni noma zikhanyiswe ngemuvaAmapaneli e-LEDokungcono kakhulu?

Yomibili imiklamo inezinzuzo kanye nezithiyo.Amaphaneli akhanya emkhawulweni abe ngawokuqala ukukhiqizwa ngobuningi.

Idizayini enokukhanya onqenqemeni ikhethwe ngenxa yezizathu ezimbalwa:

• I-light-guide plate (LGP) iyindlela ephumelelayo nelula yokusabalalisa ukukhanya, igwema ubungozi bezindawo ezikhanyayo.
• Ukuba khona kwe-LGP kusho ukuthi i-diffuser ayinasibopho sokusabalalisa ukukhanya ngokulinganayo ukuze kusetshenziswe izinto ezingabizi kakhulu, inqobo nje uma zingaphuzi ngenxa yobudala.
• Awekho amalensi adingekayo futhi idizayini ekhanyiswe onqenqemeni isebenza kahle ngama-engeli ama-LED ahlukene ahlukene.
• Ukushisa okuvela kuma-LED chips kuhlakazwa ngohlaka, ngakho ingemuva lingaba nesisindo esincane futhi ngeke lishise, ngakho umshayeli angabekwa lapha uma kudingeka.

Ngokuhamba kwesikhathi izithiyo zale ndlela zazenza zaba sobala.Into engcono kakhulu ye-LGP i-acrylic (PMMA), kodwa lokhu kungase kubize kakhulu, ngakho-ke i-polystyrene eshibhile (PS) yayivame ukusetshenziswa.Uma ingahlanganiswa nezithasiselo eziqinisayo ze-UV, ama-PS LGP aphenduka aphuzi ngokuhamba kwesikhathi ukuze ukusebenza kahle kwehle, okukhiphayo kokukhanya kuphenduke okuphuzi okufiphele futhi isikhungo sephaneli sibe mnyama kuyilapho umngcele uhlala ukhanya.

Ukwengeza, ezinye izibonisi ezingemuva (bona umdwebo ongenhla) zixetshulwa ngenxa yobudala kwehlisa isithunzi ukusebenza kwamaphaneli e-LED anokukhanya kwangaphambi kwesikhathi.

Intuthuko yobuchwepheshe manje isivumele isizukulwane esisha samaphaneli e-LED akhanyisa emuva ukuthi yethulwe.Lezi zivame ukusebenza kahle kakhulu ngezindleko zeyunithi eziphansi kunamaphaneli e-LED adlule.

• Ama-LED asebenze kahle kakhulu, ngakho-ke inzuzo yokushisa etholakala ekwakhiweni okukhanyisiwe okusemaceleni yaba yinto engabalulekanga kangako.Imiklamo ekhanyiswe ngemuva ayisashisi kangangokuthi umshayeli akakwazi ukubekwa ngemuva.
• Amalensi ashibhile ukukhiqiza futhi izinto zokunamathisela zesimanje zisho ukuthi zingagxilwa ngokuvikelekile ku-LED ngayinye ukuze zenze ukusatshalaliswa okukhanyayo okulinganayo ngaphandle kwengozi yokuthi azowa - ukwehluleka kwamanye amaphaneli angemuva futhi ashibhile.
• Ama-Micro-prismatic diffuser avame kakhulu, angabizi kakhulu futhi asebenza kangcono, ngakho-ke isenzo esiphindwe kabili senhlanganisela ye-LGP/diffuser asisadingeki.
• Ukuqedwa kwe-LGP kumiklamo ekhanyiswe ngemuva kusho ukuthi ukonga amandla okungenzeka kukhulu kunemiklamo ekhanyiswe onqenqemeni, uma zonke ezinye izici zilingana.

Imakethe yezibani manje yamukela amaphaneli anokhanyi olungemuva kalula njengamaphaneli anokhanyi onqenqemeni futhi, ngenxa yokuthi amaphaneli anamakhanyi angemuva awadingi i-LGP noma isibonisi sangemuva, ngokuvamile ayizindleko eziphansi kanye namaphaneli e-LED asebenza kahle kakhulu atholakalayo.

Yiziphi izinkinga ezishibhileamaphaneli e-LED akhanyise emuva?

Yilokhu okufanele ukubheke.

• Ambalwa kakhulu ama-LED asetshenziswayo.Ama-LED ambalwa kakhulu (ngokuvamile angama-36 noma ngaphansi) asho ukuthi kufanele ashayelwe ngamandla aphezulu ukuze akhiqize okukhipha ukukhanya okudingekayo.Uma kuqhathaniswa nemiklamo esebenzisa ama-LED amaningi, lokhu kungasebenzi kahle (ama-LED asebenza kahle kakhulu ngamaza okushayela aphansi), akhiqiza ukushisa okwengeziwe, afinyeze ukuphila kwama-LED futhi asheshise ukwehla kwe-lumen.
• Imizimba yePlastiki.Amaphaneli angemuva angcono asebenzisa umzimba wensimbi.Lokhu kusebenza kangcono njengesitha sokushisa kunomzimba wepulasitiki (oshibhile).Ama-LED akhiqiza ukushisa okuthile futhi lokhu kudinga ukuchithwa uma ukuphila kwawo kungafushaniswa ngokuqhubekayo.
• Ukusabalalisa ukukhanya akudluleli.Kuphaneli ekhanyiswe kahle ngemuva i-LED ngayinye inelensi ngayinye futhi amalensi aklanywe ngendlela yokuthi ukukhanya kwe-LED ngayinye kweqe ukukhanya okuvela komakhelwane bayo.Lokhu kuzokhiqiza umthelela okhanyayo nokuqina okuthile uma kwenzeka i-LED eyodwa ihluleka.Idizayini yelensi engalungile kanye nenani eliphansi lama-LED kungenzeka linciphise ukugqagqana phakathi kwama-LED futhi kwandise ubungozi bamachashazi akhanyayo namnyama ngaphambili kokufaka.
• Ingabe amalensi ami aqinile?Isikhathi kuphela esizosho, kodwa ingozi iwukuthi ukushisa okukhiqizwa ama-LED, kuhlanganiswe ne-adhesive eshibhile esetshenziswe kabi, kuzobangela ukuba ama-lens awe.Umphumela uzoba ukusabalalisa kokukhanya okungalingani kanye nokucwebezela futhi.
• Umshayeli owakhelwe ngaphakathi.Abakhiqizi bangonga imali ngokwakha umshayeli emzimbeni, kodwa lokhu kunezithiyo eziningi.Awukwazi ukushintshwa uma kuba nenkinga futhi ngeke kube khona izinketho zokufiphaza noma eziphuthumayo.Kuyindlela eguquguqukayo kakhulu.
• Hlola amakhona ohlaka.Kumaphaneli ashibhile kuzobonakala ukujoyina okungabukeki.

UGR <19 ngeamaphaneli e-LED anokukhanya ngemuva nasekupheleni.

Yomibili imiklamo ingakwazi, ngekhava yangaphambili engakwesokudla, ikhiqize ukusebenza okuhle kwe-UGR.Ukuze uqhathanise amabhrendi ahlukene namamodeli bheka amathebula e-UGR ayingxenye yedatha ye-photometric okufanele itholakale kubo bonke abakhiqizi abathembekile.
