Kuluntu lwanamhlanje, iziboniso ze-LED zangaphandle ziye zaba yeyona nto iphambili yokusasazwa kolwazi kunye nomboniso wentengiso. Nokuba kwiibhloko zorhwebo, amabala emidlalo okanye izikwere zedolophu, iziboniso ze-LED ezikumgangatho ophezulu zineempembelelo ezibonakalayo ezijonge ngamehlo kunye nobuchule obubalaseleyo bokuhambisa ulwazi. Ke, zeziphi izinto eziphambili ekufuneka siziqwalasele xa sikhetha olona mboniso lubalaseleyo we-LED wangaphandle? Eli nqaku liza kuxubusha ngokweenkcukacha kwiinkalo ezininzi ezifana ne-pixel pitch, umgangatho obonakalayo, ukuqina kokusingqongileyo, inkxaso yenkonzo epheleleyo, inqanaba lokukhusela kunye nofakelo olulula.
1. I-pixel pitch
1.1 Ukubaluleka kwePixel Pitch
I-pixel pitch ibhekisa kumgama osembindini phakathi kweepikseli ezimbini ezimeleneyo kwisiboniso se-LED, ngokwesiqhelo kwiimilimitha. Ngomnye wemiba ebalulekileyo emisela isisombululo kunye nokucaca komboniso. Ipixel encinci inokubonelela ngesisombululo esiphezulu kunye nemifanekiso emihle, ngaloo ndlela iphucula amava okubonwayo.
1.2 UKhetho lwePixel Pitch
Xa ukhetha i-pixel pitch, umgama wofakelo kunye nomgama wokubukela wesiboniso kufuneka uqwalaselwe. Ngokuqhelekileyo, ukuba abaphulaphuli babukele umboniso kumgama osondeleyo, kuyacetyiswa ukuba ukhethe i-pitch pitch encinci ukuqinisekisa ukucaca kunye nokucoleka komfanekiso. Umzekelo, kumgama wokubukela we-5-10 yeemitha, i-pixel pitch yeP4okanye encinci ingakhethwa. Imiboniso enomgama omde wokujonga, onje ngebala lezemidlalo elikhulu okanye isikwere sesixeko, iphikseli enkulu ngokulinganayo, efanaP10okanye iP16, inokukhethwa.
2. Umgangatho obonakalayo
2.1 Ukuqaqamba kunye nothelekiso
Ukukhanya kunye nokungafani komboniso we-LED wangaphandle kukuchaphazela ngokuthe ngqo ukubonakala kwayo kwiindawo ezikhanyayo ezikhanyayo. Ukukhanya okuphezulu kuqinisekisa ukuba isiboniso sihlala sibonakala ngokucacileyo emini naphantsi kwelanga elithe ngqo, ngelixa ukuchasana okuphezulu kwandisa ukubekeka kunye nokubonakaliswa kombala womfanekiso. Ngokubanzi, ukuqaqamba kwesiboniso se-LED sangaphandle kufuneka sifikelele kwii-nits ezingaphezu kwe-5,000 ukuhlangabezana neemfuno zeendawo ezahlukeneyo.
2.2 Ukusebenza koMbala
Umboniso we-LED okumgangatho ophezulu kufuneka ube nombala obanzi we-gamut kunye nokuveliswa kombala ophezulu ukuqinisekisa ukuba umfanekiso obonisiweyo uqaqambile kwaye ungokoqobo. Xa ukhetha, unokunikela ingqalelo kumgangatho wesibane sesibane se-LED kunye nokusebenza kwenkqubo yokulawula ukuqinisekisa ukusebenza ngokuchanekileyo kombala.
2.3 Iengile yokujonga
Uyilo olubanzi lokujonga i-angle luqinisekisa ukuba umfanekiso uhlala ucacile kwaye umbala uhlala uhambelana xa ujonga umboniso kwii-angles ezahlukeneyo. Oku kubaluleke kakhulu kwimiboniso yangaphandle, kuba ababukeli badla ngokuba nee-angles ezahlukeneyo zokujonga, kwaye i-angle yokujonga ebanzi inokuphucula amava okubukela ngokubanzi.
3. Ukuqina kokusingqongileyo
3.1 Ukuxhathisa iMozulu
Izikrini zokubonisa i-LED zangaphandle kufuneka zijongane neemeko zemozulu ezinzima ezinjengomoya, imvula, kunye nelanga ixesha elide, ngoko kufuneka zibe nokuxhathisa kwemozulu. Xa ukhetha, kufuneka ubeke ingqalelo kwizalathisi zokusebenza zesikrini sokubonisa ezifana nokungangeni kwamanzi, uthuli, kunye nokuchasana kwe-UV ukuqinisekisa ukuba inokusebenza ngokuzinzileyo kwiindawo ezahlukeneyo.
3.2 Ukuguquguquka kweqondo lobushushu
Umboniso kufuneka usebenze ngokufanelekileyo kwiindawo zombini eziphezulu kunye nezantsi, kwaye ngokuqhelekileyo unomgangatho wokushisa osebenzayo. Ngokomzekelo, ukukhetha umboniso onokusebenza kwi--20 ° C ukuya ku-50 ° C kunokuqinisekisa ukuba inokusebenza ngokuzinzileyo phantsi kweemeko zemozulu ezinzima.
4. Inkxaso yeNkonzo yoMjikelo wonke
4.1 Inkxaso yobuGcisa
Ukukhetha umthengisi onenkxaso yobugcisa obugqibeleleyo kunokuqinisekisa ukuba unokufumana uncedo ngexesha xa uhlangabezana neengxaki ngexesha lokusetyenziswa kwesiboniso. Inkxaso yobuchwephesha kubandakanywa ukufakela kunye nokulungiswa kweempazamo, ukusebenza kwenkqubo kunye nokulungisa iingxaki zizinto ezibalulekileyo zokuphucula amava omsebenzisi.
4.2 Inkonzo yasemva kokuthengisa
Inkonzo yomgangatho ophezulu emva kokuthengisa inokuqinisekisa ukuba isikrini sokubonisa sinokulungiswa kwaye sitshintshwe ngokukhawuleza xa singaphumeleli. Ukukhetha umthengisi onesiqinisekiso sexesha elide emva kokuthengisa kunokunciphisa iindleko zokugcina kunye nobungozi bokusebenza ngexesha lokusetyenziswa.
5. Inqanaba loKhuseleko
5.1 Inkcazo yeNqanaba loKhuselo
Inqanaba lokukhusela lidla ngokubonakaliswa yikhowudi ye-IP (Ingress Protection). Amanani amabini okuqala abonisa amandla okukhusela kwizinto eziqinileyo kunye nolwelo ngokulandelelanayo. Umzekelo, inqanaba eliqhelekileyo lokhuseleko lweziboniso ze-LED zangaphandle yi-IP65, oku kuthetha ukuba ayinathuli ngokupheleleyo kwaye ikhusela ukutshiza kwamanzi kuzo zonke iindlela.
5.2 Ukukhethwa kweNqanaba loKhuselo
Khetha inqanaba lokhuseleko elifanelekileyo ngokwemeko-bume yofakelo yesikrini sokubonisa. Umzekelo, iziboniso zangaphandle zifuna ubuncinci ukuba zibenezinga lokhuseleko le-IP65 ukukhusela kwimvula nothuli. Kwiindawo ezinemozulu exhaphakileyo rhoqo, ungakhetha umgangatho wokhuseleko ophezulu ukunyusa ukuqina kwesiboniso.
6. Kulula ukufaka
6.1 Uyilo oluKhala
Uyilo lokubonisa ukukhanya lunokwenza lula inkqubo yokufakela kunye nokunciphisa ixesha lokufakela kunye neendleko zabasebenzi. Ngexesha elifanayo, kunokunciphisa iimfuno zokuthwala umthwalo kwisakhiwo sofakelo kunye nokuphucula ukuguquguquka kokufakela.
6.2 Uyilo lweModyuli
Isikrini sokubonisa samkela uyilo lwemodyuli kwaye sinokuchithwa ngokulula, sidityaniswe kwaye sigcinwe. Xa imodyuli yonakele, kuphela inxalenye eyonakalisiweyo idinga ukutshintshwa endaweni yomboniso wonke, enokunciphisa kakhulu iindleko zokugcinwa kunye nexesha.
6.3 Izixhobo zokuFaka
Xa ukhetha, nikela ingqalelo kwizinto zokuxhoma ezibonelelwa ngumthengisi, ezifana nezibiyeli, iifreyimu kunye nezixhumi, ukuqinisekisa ukuba zinomgangatho othembekileyo kwaye ziyakwazi ukulungelelanisa neemfuno zeendawo ezahlukeneyo zokufakela.
Ukuqukumbela
Ukukhetha olona mboniso ubalaseleyo wangaphandle we-LED ngumsebenzi onzima ofuna indibaniselwano yezinto, kubandakanya i-pixel pitch, umgangatho wokubonwayo, ukuqina kokusingqongileyo, inkxaso yenkonzo epheleleyo, inqanaba lokhuseleko, kunye nofakelo olulula. Ukuqonda okunzulu kwezi zinto kunokusinceda senze ukhetho olunolwazi ukuqinisekisa ukuba umboniso unokubonelela ngokusebenza okugqwesileyo kunye nokusebenza okuzinzile kwexesha elide kwiindawo ezahlukeneyo.
