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 ziqedwa 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 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. 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, engezwe 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 ekukhanyeni kwezimboni ngenxa yezimpawu zayo zokonga amandla nokuvikelwa kwemvelo, ukusetshenziswa kwamandla okuphansi, ukusebenza kahle okukhanyayo, impilo ende, iqinile futhi ihlala isikhathi eside (ingenamanzi, i-dustproof, 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!
