Selokhu ukukhanya kwangena enkathini yezibani ze-fluorescent, izibani ezihambisanayo nezibani bezilokhu zikhukhula indawo yethu yokukhanya.Ngokuya ngesimiso esikhanyayo sezibani ze-fluorescent, inkinga yokucwayiza ayizange ixazululwe kahle.Namuhla, singene enkathini yokukhanyisa kwe-LED, kodwa inkinga yokucwayiza kokukhanya isekhona.
Yini i-flicker
I-Flicker ukushintsha kokuqina kokukhanya noma ukukhanya ngesikhathi esithile.Ukucwayiza kombani kwenzeka ezinhlelweni eziningi zokukhanyisa, okuhlanganisa ukudubula okuhamba kancane ku-TV, ukukhanya komgwaqo, izinkambu ezihlukahlukene zokukhanyisa okuvamile nezindawo zokusebenza kusetshenziswa imishini ejikelezayo ngokushesha.I-Flicker izothinta impilo yomuntu, futhi izinga lomthelela lincike ebuningini bokucwayiza kanye nokuzwela komuntu siqu ukucwayiza.Ukucwayiza kwefrikhwensi ephezulu ngeke kube nomthelela omkhulu emzimbeni womuntu, kodwa ukucwayiza okuphansi okungaphansi kuka-120 Hz kulula ukuthi kuthinte impilo yomuntu.
Umsebenzi wesisindo wokuzwela kwamehlo omuntu ukuze acwayize
Ukulimala kokucwayiza kokukhanyisa
I-Flicker yomthombo wokukhanya ihlobene eduze ne-migraine, ikhanda elibuhlungu, i-autism, ukukhathala kwamehlo, ukungaboni kahle nezinye izifo zemizwa.Ucwaningo luye lwabonisa ukuthi i-low-frequency, ububanzi bomthombo wokukhanya we-3-70Hz scintillation ingase ibangele i-photosensitive isithuthwane kwabanye abantu abazwelayo;Imvamisa ye-100Hz flicker ikhonjwe ukuthi ibangele ikhanda kanye ne-migraine;Umthombo wokukhanya olokozayo ongu-120Hz ungase uthinte isimo sengqondo sabantu, njengesithukuthezi nokukhathazeka.Inkohliso ebonakalayo ebangelwa umphumela wokucwayiza kanye nokunyakaza kwemishini okuhlobene kuyingozi kakhulu ezindaweni zezimboni.Ngakho-ke, ukulinganisa ngokunembile nokuhlola izici ezicwayizayo zemikhiqizo yokukhanyisa kuhlobene ngokuqondile nempilo yabantu, okuyinkinga ephuthumayo okufanele ixazululwe.
Izimbangela zokucwayiza
Izizathu zokucwayiza kwezibani ze-LED azihlanganisi izici zokunikezwa kwamandla kuphela, kodwa futhi nezici zokusebenza kobuchwepheshe bomthombo wokukhanya kanye nomklamo wokukhanyisa ongenangqondo.I-Ripple current ingenye yezimbangela ezibalulekile zokucwayiza ekunikezeni amandla amalambu amaningi okukhanyisa.I-Ripple current ingxenye ye-AC esekhona ngemva kokulungiswa nokuhlunga.I-Ripple current ibekwe phezulu ku-DC futhi inamaza namajika ahlukene.Le ngxenye ye-AC yenza amandla emojula ye-LED aguquguquke, okuzoshintsha ukukhanya.Ubuningi nemvamisa ye-AC ebekwe phezulu yizici ezibalulekile zokucwayiza.

Umdwebo wencazelo yenkomba yokucwayiza kanye nephesenti lokucwayiza
Ungasusa kanjani i-flicker
Ngaphezu komsebenzi wokuqeda ubumnyama nokukhanyisa imvelo, ukukhanya kufanele kucabangele ukusebenza kwezempilo kwemikhiqizo.Ukungabi yingozi kubantu kuyingxenye yokusebenza kwezibani okungafanele kushaywe indiva.
Ithintwa ukulungiswa kwamandla kagesi (50Hz ngokwendinganiso yaseYurophu), imvamisa yamanje ye-ripple engxenyeni enkulu yedrayivu ye-LED iphindwe kabili kunaleyo yokunikezwa kwamandla, okungaba ngu-100Hz.Ngaphezu kwalokho, uma kuqhathaniswa nemithombo yokukhanya evamile, ama-LED angaguqula ngokushesha ukusebenza kwamanje kube ukukhanya.Ukuze kuzuzwe umphumela wokukhipha ukukhanya ngaphandle kokucwayiza ngangokunokwenzeka, umshayeli wekhwalithi ephezulu we-LED nokuhambisana phakathi komshayeli, i-dimmer nemojula ye-LED kubalulekile.Isithombe esilandelayo siyindlela evamile yokuhlola idivayisi yokulawula ngokusebenzisa "i-ripple yamanje yokuphumayo" noma "i-AC ephakeme kakhulu".Ngokuvamile, inani elibonisiwe lingu-100Hz.Lapho inani liphansi, ingozi yokucwayiza iyancipha.
IEEE Std 1789-2015
Izithombe Ezinconyiwe ze-IEEE Zokulungisa Okwamanje Ekukhanyeni Okuphezulu kwe-LED ukuze Unciphise Izingozi Zezempilo Ezibukelini
Amalambu ama-LED akwa-Wellway nama-lighting, kungakhathaliseki ukuthi amalambu angangeni manzi, amalambu abakaki, amaphaneli namalambu angangeni uthuli, okuhlanganisa amamodeli ayisisekelo namamodeli ezinzwa izimo eziphuthumayo, konke kuyawubona umsebenzi ngaphandle kokucwayiza.Ukunikezwa kwamandla kwekhwalithi ephezulu okusetshenziswa isibani kunganciphisa ukuphuma kwe-ripple futhi kubone ukufanelana okuphelele nezingxenye zesibani.
(Ezinye izithombe ziphuma ku-inthanethi. Uma kukhona ukwephulwa komthetho, sicela usithinte futhi uzisuse ngokushesha)
