Ukukhanya kuyimveliso enkulu kwimbali yoluntu, kwaye ukubonakala kokukhanya kombane kuye kwakhuthaza kakhulu ukuphuhliswa kwempucuko yabantu.
Isibane sokuqala esisetyenzisiweyo sisibane se-incandescent, esasungulwa kunye nobunzima obuveliswe nguThomas Alva Edison ngo-1879. ukusebenzisa.Nangona kunjalo, ngenxa yokuba ukuguqulwa kwamandla okusebenza kwezibane ze-incandescent kuncinci, zipheliswa ngokuthe ngcembe yimarike.
Ngophuhliso loluntu, izibane ze-fluorescent (izibane ze-fluorescent) zaqala ukubonakala kwi-1930s.Ngo-1974, kwavela umgubo we-fluorescent obomvu, oluhlaza kunye nokukhanya okuluhlaza okwesibhakabhaka, kwaye ukuwusebenzisa njengento ekrwada kwizibane ze-fluorescent kusindisa kakhulu amandla.Izibane zeFluorescent zinobomi obude benkonzo, ukusebenza kakuhle kokukhanya okuphezulu, indawo enkulu yokukhanyisa, kwaye inokulungiswa kwimibala eyahlukeneyo yokukhanya.Kodwa iityhubhu zezibane ze-fluorescent zidla umbane omninzi, kwaye uninzi lombane lusetyenziswa njengobushushu.
Emva koko kwaphuma izibane eziphezulu ze-sodium kunye nezibane ze-metal halide, ezibizwa ngokuba yimithombo yokukhanyisa kwisizukulwana sesithathu.Izibane ze-sodium ezinoxinzelelo oluphezulu zibonakaliswe ngokukhanya okuphezulu okukhanyayo, ukusetyenziswa kwamandla aphantsi, ubomi obude, ukungena kwenkungu enamandla kwaye akukho lula ukugqwala, njl. Ngoko ke, izibane ze-sodium ezinoxinzelelo oluphezulu zisetyenziswa ngokubanzi kwiindawo ezahlukeneyo zokukhanyisa ngokubanzi.Iingenelo zezibane ze-metal halide kukuba ukukhanya okukhanyayo kuphezulu kakhulu, ukukhanya okukhanyayo kuphezulu njenge-80-120Lm / W, isalathisi sombala siphezulu, ukuncitshiswa kombala kulungile, kwaye i-Ra inokufikelela kuma-90. isetyenziswa ekukhanyisweni kwangaphakathi kwamabala emidlalo, kudederhu lweevenkile ezinkulu, izityalo zoshishino, izikwere zezitalato, iidokhi nezinye iindawo.
Eyokugqibela kukukhanya kwe-semiconductor esetyenziswa ngokubanzi - ukukhanya kwe-LED.Ukuvela kwezibane ze-LED kuye kwaphula ingcamango yokwakhiwa komthombo wokukhanya kwendabuko, kwaye lutshintsho olukhulu lokukhanya oluqale ngokutsha emva kwebhalbhu yesibane.Isetyenziswa kwizibane ezibonisa uqhushumbo kunye nezibane ezikhanyisayo ngokubanzi, ikakhulu ezimhlophe ze-LED ezingatshatanga, zongezwa ngokudityaniswa kwe-LED kunye ne-SMD, ukuveliswa kobuninzi bezibane ezijingayo ze-LED, izibane zeqonga le-LED kunye nezinye izibane zokukhanyisa kwimizi-mveliso, ukwaphula imida yoshishino lokukhanyisa ngokwesini. .Isetyenziswa kakhulu ekukhanyeni kwemizi-mveliso ngenxa yeempawu zayo zokugcina amandla kunye nokukhuselwa kwendalo, ukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle okukhanyayo, ubomi obude, bomelele kwaye buhlala ixesha elide (ukungangeni kwamanzi, uthuli, i-anticorrosion, i-explosion-proof).
Kwixesha lobukrelekrele benkulungwane yama-21, imakethi yokukhanya ekrelekrele ibonisa ukukhula okukhulu okunokwenzeka kwiminyaka embalwa ezayo.Ngenkqubela phambili yamaxesha, ukuguqulwa kwezibane kunye nezibane ziyaqhubeka, kwaye yintoni utshintsho oluya kwenzeka ekukhanyeni kwe-LED, siya kulinda kwaye sibone.
Ezi zikhanyiso zintle zangaphakathi zilapha ngasentla zivela kwinkampani yokukhanya yombane kaDongguan Mingpin.
Ukuba unomdla kwezi mveliso, nceda uqhagamshelane nabasebenzi bokuthengisa abangezantsi, baya kubuyela kuwe ngokukhawuleza!
