1. Isingeniso
Izibonisi ze-LED seziphenduke amadivayisi abalulekile kuzilungiselelo ezihlukahlukene. Ukuqonda umehluko phakathi kwezibonisi ze-LED zasendlini nezangaphandle kubalulekile njengoba zihluka kakhulu ekwakhiweni, kumapharamitha wobuchwepheshe kanye nezimo zohlelo lokusebenza. Lesi sihloko sizogxila ekuqhathaniseni izibonisi ze-LED zangaphakathi nangaphandle mayelana nokukhanya, ukuminyana kwe-pixel, i-engeli yokubuka kanye nokuvumelana nezimo zemvelo. Ngokufunda lesi sihloko, abafundi bazokwazi ukuqonda ngokucacile umehluko phakathi kwezinhlobo ezimbili, banikeze isiqondiso ekukhetheni isibonisi se-LED esifanele.
1.1 Yini isibonisi se-LED?
Isibonisi se-LED (Isibonisi se-Light Emitting Diode) siwuhlobo lwemishini yokubonisa esebenzisa i-diode ekhipha ukukhanya njengomthombo wokukhanya, esetshenziswa kabanzi kuzo zonke izinhlobo zezenzakalo ngenxa yokukhanya kwayo okuphezulu, ukusetshenziswa kwamandla okuphansi, impilo ende, isivinini sokuphendula okusheshayo kanye ezinye izici. Ingabonisa izithombe ezimibalabala nolwazi lwevidiyo, futhi iyithuluzi elibalulekile lokusabalalisa ulwazi lwesimanje kanye nokuboniswa okubonakalayo.
1.2 Ukubaluleka nokubaluleka kwezibonisi ze-LED zasendlini nangaphandle
Izibonisi ze-LED zihlukaniswa ngezinhlobo ezimbili eziyinhloko, zasendlini nangaphandle, ngokusekelwe endaweni ezisetshenziswa kuyo, futhi uhlobo ngalunye luhluke kakhulu ekuklanyweni nasekusebenzeni. Ukuqhathanisa nokuqonda izici zezibonisi ze-LED zasendlini nangaphandle kubalulekile ekukhetheni isisombululo esifanele sokubonisa nokuthuthukisa ukusetshenziswa kwaso.
2.Incazelo kanye nesigcawu sohlelo lokusebenza
2.1 Isibonisi se-LED sangaphakathi
Isibonisi se-LED sangaphakathi siwuhlobo lwesisetshenziswa sokubonisa esiklanyelwe indawo yasendlini, samukela i-diode ekhipha ukukhanya njengomthombo wokukhanya, enokucaca okuphezulu, i-engeli yokubuka ebanzi kanye nokuzalaniswa kombala okuphezulu. Ukukhanya kwayo kumaphakathi futhi kulungele ukusetshenziswa ngaphansi kwezimo zokukhanyisa ezizinzile.
2.2 Izigcawu zokubonisa ze-LED ezivame ukusetshenziswa
Igumbi Lenkomfa: Isetshenziselwa ukubonisa izethulo, izinkomfa zevidiyo nedatha yesikhathi sangempela ukuze kuthuthukiswe ukusebenza kahle komhlangano nokusebenzisana.
Isitudiyo: Isetshenziselwa ukukhombisa ingemuva kanye nokushintsha isikrini ngesikhathi sangempela eziteshini ze-TV nama-webcast, kuhlinzeka ngekhwalithi yesithombe enencazelo ephezulu.
Izitolo ezinkulu: Isetshenziselwa ukukhangisa, ukuboniswa kolwazi kanye nokunyuswa komkhiqizo ukuheha ukunaka kwamakhasimende nokuthuthukisa ulwazi lokuthenga.
Imibukiso: isetshenziswa emibukisweni nakumamnyuziyamu ekubukisweni kwemikhiqizo, ukwethulwa kolwazi kanye nokubukisa okusebenzisanayo, okuthuthukisa ulwazi lokubukwa kwezithameli.
2.3 Isibonisi se-LED sangaphandle
Isibonisi se-LED sangaphandle siyidivayisi yokubonisa eyenzelwe indawo yangaphandle enokukhanya okuphezulu, okungangeni manzi, okungangenwa uthuli kanye nokumelana ne-UV, ekwazi ukusebenza ngokujwayelekile ngaphansi kwezimo zezulu ezihlukahlukene. Iklanyelwe ukuhlinzeka ngokubonakala okucacile kumabanga amade nokumboza i-engeli yokubuka ebanzi.
2.4 Ukusetshenziswa okuvamile kwezibonisi ze-LED zangaphandle
Amabhodi okukhangisa:Isetshenziselwa ukubonisa izikhangiso zentengiso nokuqukethwe kokuphromotha ukuze kufinyelelwe izethameli eziningi futhi kuthuthukiswe ukuqwashisa ngomkhiqizo kanye nomthelela wemakethe.
Izinkundla: Isetshenziselwa ukubonisa amaphuzu wesikhathi sangempela, ukusakaza bukhoma kwemicimbi nokusebenzelana kwezithameli ukuze kuthuthukiswe umuzwa wokubuka kanye nesimo somcimbi.
Imibukiso yolwazi: ezindaweni zomphakathi njengezikhumulo zezindiza, iziteshi zesitimela, izitobhi zamabhasi neziteshi zesitimela esingaphansi komhlaba, ukuhlinzeka ngolwazi lwethrafikhi yesikhathi sangempela, izimemezelo nezaziso zesimo esiphuthumayo, ukwenza kube lula ukufinyelela komphakathi olwazini olubalulekile.
Izikwele zedolobha nezimpawu zendawo: ukusakazwa bukhoma kwemicimbi emikhulu, umhlobiso womkhosi nokukhuthazwa kwedolobha
3. Ukuqhathaniswa kwamapharamitha wezobuchwepheshe
Ukukhanya
Isidingo Sokukhanya kwesibonisi se-LED sangaphakathi
Isibonisi se-LED sasendlini ngokuvamile sidinga izinga eliphansi lokukhanya ukuze kuqinisekiswe ukuthi asiphuphutheki lapho sibukwa ngaphansi kokukhanya okwenziwa nezimo zokukhanya kwemvelo. Ukukhanya okuvamile kusuka ku-600 kuya ku-1200 nits.
Izidingo Zokukhanya Zokuboniswa Kwe-LED Kwangaphandle
Isibonisi se-LED sangaphandle sidinga ukukhanya kakhulu ukuze kuqinisekiswe ukuthi sihlala sibonakala elangeni eliqondile noma ekukhanyeni okukhanyayo. Ukukhanya kuvamise ukuba sebangeni lama-nits angu-5000 kuya kwangu-8000 noma ngaphezulu ukuze ubhekane nezimo zezulu ezihlukahlukene nokuhluka kokukhanya.
Ukuminyana kwePixel
I-Pixel Density yesibonisi se-LED sangaphakathi
Isibonisi se-LED sasendlini sinokuminyana kwe-pixel ephezulu ukuze ubuke eduze. Ukuphakama kwephikseli okujwayelekile kuphakathi kuka-P1.2 no-P4 (okungukuthi, 1.2 mm kuya ku-4 mm).
I-Pixel Density yesibonisi se-LED sangaphandle
Ukuminyana kwephikseli yesibonisi se-LED yangaphandle kuphansi kakhulu njengoba kuvame ukusetshenziselwa ukubuka ibanga elide. Amaphikseli ajwayelekile asukela ku-P5 kuye ku-P16 (okungukuthi, 5 mm kuya ku-16 mm).
I-engeli yokubuka
Izidingo ze-engeli yokubuka yasendlini
Ama-engeli okubuka avundlile naqondile angu-120 degrees noma ngaphezulu ngokuvamile ayadingeka, futhi ezinye izibonisi ezisezingeni eliphezulu zingafinyelela kumadigri angu-160 noma ngaphezulu ukuze kufakwe izinhlobonhlobo zezakhiwo zasendlini nama-engeli okubuka.
Izidingo ze-engeli yokubuka yangaphandle
Ama-engeli okubuka avundlile ngokuvamile angu-100 kuya ku-120 degrees, futhi ama-engeli wokubuka aqondile angama-50 kuya ku-60 degrees. Lawa ma-engeli wokubuka angamboza uhla olukhulu lwezibukeli kuyilapho kugcinwa ikhwalithi yesithombe enhle.
4. Ukuzivumelanisa Nemvelo
Ukusebenza Okungenamanzi kanye Nothuli
Izinga Lokuvikela Lokubonisa Kwe-LED Kwangaphakathi
Isibonisi se-LED sasendlini ngokuvamile asidingi izilinganiso zokuvikela okuphezulu ngoba sifakwe endaweni ezinzile futhi ehlanzekile. Izilinganiso zokuvikela ezijwayelekile ziyi-IP20 kuye ku-IP30, evikela ezingeni elithile lokungena kothuli kodwa akudingi ukuvinjelwa kwamanzi.
Izilinganiso Zokuvikela Zokubonisa Kwe-LED Yangaphandle
Isibonisi se-LED sangaphandle sidinga ukuba nezinga eliphezulu lokuvikela ukuze sibhekane nazo zonke izinhlobo zesimo sezulu esibi. Izilinganiso zokuvikela ngokuvamile ziyi-IP65 noma ngaphezulu, okusho ukuthi isibonisi sivikelwe ngokuphelele ekungeneni kothuli futhi singamelana nokufuthwa kwamanzi kusuka kunoma iyiphi indlela. Ngaphezu kwalokho, izibonisi zangaphandle zidinga ukumelana ne-UV futhi zimelane namazinga okushisa aphezulu naphansi.
5.isiphetho
Kafushane, siyawuqonda umehluko phakathi kwezibonisi ze-LED zasendlini nezingaphandle ekukhanyeni, ukuminyana kwe-pixel, i-engeli yokubuka, nokuvumelana nezimo zemvelo. Izibonisi zasendlini zifanele ukubukwa eduze, ezinokukhanya okuphansi nokuminyana kwephikseli ephakeme, kuyilapho izibonisi zangaphandle zidinga ukukhanya okuphakeme nokuminyana kwamaphikseli okumaphakathi kumabanga ahlukene okubuka nezimo zokukhanya. Ukwengeza, izibonisi zangaphandle zidinga ukuvikela amanzi okuhle, ukuvikela uthuli, namazinga aphezulu okuvikela ezindaweni ezingaphandle ezinokhahlo. Ngakho-ke, kufanele sikhethe isisombululo esifanele sokubonisa i-LED ngezimo nezimfuneko ezahlukene. Ukuze uthole ulwazi olwengeziwe mayelana nezibonisi ze-LED, sicelaXhumana nathi.
