Ukukhanya kuyinto esungulwe kakhulu emlandweni wesintu, futhi ukubonakala kokukhanya kukagesi kuye kwakhuthaza kakhulu ukuthuthukiswa kwempucuko yomuntu.
Isibani sokuqala esizosetshenziswa kwakuyisibani se-incandescent, esasungulwa futhi isisindo sakhiqizwa nguThomas Alva Edison ngo-1879. Isibani se-Incandescent siyisizukulwane sokuqala somthombo wokukhanya kagesi, ukusebenza kahle kwawo okukhanyayo kungafinyelela cishe ku-13%, ukunikezwa kombala okuhle, i-spectrum eqhubekayo, kulula. ukusebenzisa.Kodwa-ke, ngenxa yokuthi ukusebenza kahle kokuguqulwa kwamandla kwezibani ze-incandescent kuphansi, kancane kancane kuqedwa yimakethe.
Ngokuthuthuka komphakathi, izibani ze-fluorescent (izibani ze-fluorescent) zaqala ukubonakala ngawo-1930.Ngo-1974, kwavela impushana ye-fluorescent enokukhanya okubomvu, okuluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka, futhi ukuyisebenzisa njengento eluhlaza yezibani ze-fluorescent kwasindisa kakhulu amandla.Amalambu e-Fluorescent anempilo ende yesevisi, ukusebenza kahle okuphezulu kokukhanya, indawo enkulu yokukhanyisa, futhi angashintshwa abe imibala ehlukene yokukhanya.Kodwa amashubhu ezibani ze-fluorescent adla ugesi omningi, futhi ugesi omningi usetshenziswa njengokushisa.
Kwabe sekuphuma izibani ze-sodium ezinomfutho ophezulu kanye nezibani zensimbi ze-halide, ezibizwa ngokuthi imithombo yokukhanyisa yesizukulwane sesithathu.Izibani ze-sodium ezinomfutho ophezulu zibonakala ngokusebenza kahle okuphezulu okukhanyayo, ukusetshenziswa kwamandla aphansi, impilo ende, ukungena kwenkungu eqinile futhi akulula ukugqwala, njll. Ngakho-ke, izibani ze-sodium ezicindezela kakhulu zisetshenziswa kabanzi ezindaweni ezihlukahlukene zokukhanyisa okuvamile.Izinzuzo zezibani ze-metal halide ukuthi ukusebenza kahle okukhanyayo kuphezulu kakhulu, ukusebenza kahle okukhanyayo kuphezulu njengo-80-120Lm/W, inkomba yokunikeza umbala iphezulu, ukuncishiswa kombala kuhle, futhi i-Ra ingafinyelela ku-90. Ngakho-ke, isetshenziswa ekukhanyisweni kwangaphakathi ezinkundleni zemidlalo, ezinxanxatheleni zezitolo ezinkulu, izitshalo zezimboni, izikwele zemigwaqo, amadokhu nezinye izindawo.
Okokugcina ukukhanyisa kwe-semiconductor esetshenziswa kabanzi - ukukhanyisa kwe-LED.Ukuvela kwezibani ze-LED kwephule umbono wokudala wokwakhiwa komthombo wokukhanya, futhi kuwuguquko olukhulu lokukhanya oluqale kabusha ngemva kwesibani.Isetshenziswa kumalambu ochungechunge angaqhume kanye nezibani ezijwayelekile zokukhanyisa, ikakhulukazi i-LED eyodwa emhlophe, elekelelwa ukuhlanganiswa kwe-LED kanye ne-SMD, ukukhiqizwa ngobuningi bezibani ezilengayo ze-LED, izibani zesikhulumi se-LED nezinye izibani zokukhanyisa ezimbonini, kwephula ukulinganiselwa kobulili bemboni yokukhanyisa yendabuko. .Isetshenziswa kakhulu ekukhanyisweni kwezimboni ngenxa yezimpawu zayo zokonga amandla nokuvikelwa kwemvelo, ukusetshenziswa kwamandla okuphansi, ukusebenza kahle okukhanyayo, impilo ende, iqinile futhi ihlala isikhathi eside (ingangeni manzi, ingangenisi uthuli, i-anticorrosion, i-explosion-proof).
Esikhathini esihlakaniphile sekhulu lama-21, imakethe yokukhanyisa ehlakaniphile iveza amandla amakhulu okukhula eminyakeni embalwa ezayo.Ngokuqhubeka kwezikhathi, ukuguqulwa kwezibani nezibani kuyaqhubeka, futhi yiziphi izinguquko ezizokwenzeka ekukhanyeni kwe-LED, sizolinda futhi sibone.
Lezi zakhiwo ezinhle zangaphakathi zokukhanya ngenhla zivela enkampanini yokukhanyisa izithombe zikaDongguan Mingpin limited.
Uma unentshisekelo kule mikhiqizo, sicela uxhumane nabasebenzi bokuthengisa ngezansi, bazobuyela kuwe ngokushesha ngangokunokwenzeka!
