Umthombo wokukhanya kwe-LED, obizwa ngokuba yi-light-emitting diode (Light Emitting Diode, efinyeziweyo njenge-LED) kuluntu lwanamhlanje. Kwiminyaka yakutshanje, ulwazi lwabantu ngokhuseleko lokusingqongileyo luya lusanda, kwaye umthombo wokukhanya we-LED usetyenziswa kancinci kancinci ukuthatha indawo yomthombo wokukhanya we-halogen wendabuko.
Isibane semveli esingenamthunzi sisebenzisa ibhalbhu ye-halogen njengomthombo wokukhanya, kwaye sibonakalisa ukukhanya kwindawo yotyando ngesixhobo sokubonisa esinama-multi-mirror. Umthombo wokukhanya we-halogen osetyenziswa kwesi sibane singenamthunzi onobomi obufutshane, kwaye i-spectrum ekhutshwayo ine-ultraviolet ukuya kukukhanya kwe-infrared. Nangona ubuchwepheshe banamhlanje bunokucoca uninzi lwemitha ye-ultraviolet, ukusetyenziswa kwexesha elide kwesibane sotyando se-halogen esibonakalayo kuya kubangela ukutsha kunye nokungonwabi kwisigulana.
Iimpawu eziphambili zomthombo wokukhanya we-LED bubushushu obuphantsi bomthombo wokukhanya, ukusetyenziswa kwamandla aphantsi, ubomi benkonzo ende, kunye nobushushu bombala obuhlengahlengiswayo. Xa kuthelekiswa nemithombo yokukhanya ye-halogen yendabuko, imithombo yokukhanya ye-LED ineenzuzo ezinkulu. Ngoko ke i-LED isetyenziswa njani kuyilo nasekusetyenzisweni kwezibane ezingenamthunzi zotyando.
Okwangoku, amanye amaphepha akwaxoxe ngokusetyenziswa kwawo ngokweenkcukacha:
(1) Ithiyori yoyilo lwe-optical olungengomfanekiso, indlela yoyilo lokusasazwa kokukhanya kwe-LED kunye neeparamitha zokuchonga i-photometric ziyachazwa, iimodyuli eziphambili kunye nemisebenzi yesoftware yoyilo lokukhanyisa ye-LightTools ziyaziswa, kwaye umgaqo kunye nendlela yokulandelela imitha ziyaxoxwa.
(2) Ngokusekelwe kuphando nokuxoxa ngomgaqo woyilo kunye neemfuno zoyilo lwesibane sotyando esingenamthunzi, kucetywayo isicwangciso esisekelwe kuyilo lwelensi yokubonakalisa yangaphakathi iyonke (TIR), kwaye ilensi yokubonakalisa yangaphakathi iyonke iyilwe kusetyenziswa isoftware yeLightTools, kwaye kwenziwa ukuvuna amandla ayo. Izinga kunye nokufana kuyaphuculwa. Isibane sotyando esingenamthunzi se-LED siyilwe ngendlela ye-16×4 lens array, kwaye i-interval kunye ne-rotation angle ye-lens array ziyalinganiswa, kwaye uhlalutyo lokunyamezelana kwelensi kunye novavanyo lokulinganisa lwesoftware luyagqitywa.
(3) Iisampulu zesibane sotyando se-LED esingenamthunzi zaphuhliswa, kwaye iisampulu zavavanywa ngokweemfuno zokusebenza kwesibane sotyando esingenamthunzi, kubandakanya ukukhanya okuphakathi, izinga lokukhanya elingelinye, izinga lokukhanya eliphindwe kabini, izinga lokukhanya elingaphantsi komgodi onzulu, umqadi wokukhanya. Iziphumo zovavanyo zibonisa ukuba ukusebenza kwesampulu ngokusisiseko kuyahlangabezana neemfuno zoyilo.
Kungokuphuculwa okuqhubekayo kwabantu kunye nokuphuculwa okuqhubekayo kokusebenza kweemveliso ezikhoyo apho ixesha elitsha lisebenza kakuhle ngakumbi kunye neemveliso zezibane zotyando ezingenamthunzi ezingabizi kakhulu. Amaxesha ayatshintsha, iimfuno zabantu ziyaphucuka, thina Njengomvelisi wezibane zotyando ezingenamthunzi, siza kuqhubeka nokuvelisa iimveliso ezingcono zokukhonza uluntu.
