Izibane ze-LED ezingenamthunzi, njengesibane esisetyenziswa ngokubanzi esingenamthunzi, zineempawu ze-spectrum emxinwa, umbala wokukhanya ococekileyo, amandla akhanyayo, ukusetyenziswa kwamandla aphantsi, kunye nobomi benkonzo ende, ephezulu kunemithombo yokukhanya ye-halogen jikelele. Xa kuthelekiswa nezibane zesiqhelo zotyando ze-halogen ezingenathunzi, izibane ze-LED ezingenasithunzi zicombulula ubugwenxa bamandla aphantsi, unikezelo lombala olulambathayo, indawo encinci yojoliso, ubushushu obuphezulu, kunye nobomi benkonzo emfutshane yezibane zesintu ezingenasithunzi. Ke, yintoni umsebenzi wezibane ze-LED ezingenamthunzi?
Isibane esingenasithunzi se-LED sisixhobo sonyango esiyimfuneko kwisebe lotyando. Ngethuba lenkqubo yotyando, akuyimfuneko kuphela ukuba "ungabi nesithunzi", kodwa ukhethe ukukhanya ngokukhanya okulungileyo, okungakwazi ukwahlula umehluko wombala phakathi kwegazi kunye nezinye izakhiwo kunye nezitho zomzimba womntu kakuhle. Uhlalutyo olusebenzayo lwezibane ze-LED ezingenamthunzi:

1. Umthombo wokukhanya we-LED ozinzileyo. Uthotho lwezibane ze-ZW ezingenasithunzi zisebenzisa itekhnoloji yokukhanyisa eluhlaza kunye nokusetyenziswa kancinci, kunye nobomi bebhalbhu ukuya kuthi ga kwiiyure ezingama-50000, ubude bamaxesha aphindwe kaninzi kune-halogen engenathunzi yezibane. Ukusetyenziswa kohlobo olutsha lomthombo wokukhanya obandayo we-LED njengokukhanya kotyando ngumthombo wokukhanya oyinyaniso obandayo, kunye nokunyuka kwamaqondo obushushu kwintloko kagqirha kunye nommandla wenxeba.
2. Uyilo oluhle kakhulu lwe-optical. Ukusebenzisa i-software yekhompyutha incedise ukuyila iteknoloji ukulawula i-engile yokufakela emacala-ntathu kwilensi nganye, okwenza indawo yokukhanya ibe ngqukuva; I-lens enobuchule obuphezulu kwii-engile ezincinci ibangela ukukhanya okuphezulu kunye nokukhanya okugxininiswe ngakumbi.
3. Uyilo olulodwa lwesakhiwo samacandelo omthombo wokukhanya. Ibhodi yomthombo wokukhanya yenziwe nge-substrate ye-aluminium edibeneyo, enciphisa inani elikhulu leentambo eziphaphazelayo, yenza lula isakhiwo, iqinisekisa umgangatho ozinzile, iphucula ukutshatyalaliswa kobushushu, kwaye inobomi obude benkonzo.
4. Ulawulo lwamabala olufanayo. Isixhobo esigxininisekileyo esiphakathi sinokufikelela ukulungelelaniswa okufanayo kobubanzi bendawo.
5. Kulula ukusebenzisa ubushushu bombala kunye nemisebenzi yenqanaba lokuqaqamba. PWM stepless dimming, elula kwaye ecacileyo inkqubo yokusebenza ujongano, uyilo bhetyebhetye kunye nobushushu bombala ohlengahlengiswayo.
6. Inkqubo yekhamera yenkcazo ephezulu. Ngokwamkela itekhnoloji ye-high-frequency pulse wide dimming technology, inkqubo yekhamera esembindini / yangaphandle inokumiselwa ukusombulula ingxaki yescreen flicker kwinkqubo yekhamera.
7. Ukulawulwa kwentshukumo, imbuyekezo yethunzi, kunye neminye imisebenzi ibonelela abasebenzi bezonyango ngemisebenzi elula ngakumbi.

Amanyathelo okhuseleko
Ukuqwalasela iimfuno ezikhethekileyo zokhuseleko lwezixhobo zonyango, amanyathelo okhuseleko ahambelanayo kufuneka athathwe kuwo onke amanqanaba enkqubo. Okokuqala, igumbi lokusebenza liyindawo eyomeleleyo, kwaye kubaluleke kakhulu ukukhusela i-microcontroller ekuqhekekeni, ngoko ke kufuneka kuthathwe amanyathelo alandelayo.
(1) Uyilo lwezixhobo zokusebenza kunye neenkqubo zokusetha ngokutsha kwangaphakathi kufuneka ziphathwe ngobunono;
(2) Izibonakaliso zokuphazamiseka kobuxoki kufuneka zipheliswe, ngoko ke inkqubo yonke ithatha ukuhlukaniswa kombane okupheleleyo ukukhusela ukuphazamiseka phakathi kweendawo ezahlukeneyo zesekethe. Ukongeza, indlela yokukhangela i-Modbus redundancy nayo yamkelwa.
(3) Ukukhanya okuphezulu okumhlophe kwe-LED kunexabiso eliphezulu. Ukuze ugweme umonakalo, kuyimfuneko ukuphelisa impembelelo yegridi yamandla kunye nomonakalo kwinkqubo. Ngoko ke, i-overvoltage kunye ne-overcurrent yokukhusela isiphaluka esizenzekelayo samkelwa. Xa i-voltage okanye i-current idlula i-20% yexabiso elimiselweyo, inkqubo inqumla ngokuzenzekelayo amandla okuqinisekisa ukhuseleko lwesekethe yenkqubo kunye nokukhanya okuphezulu kwe-LED.
