Kuyinto evamile kakhulu ukuthi izibani eziholayo ziba mnyama futhi zibe mnyama njengoba zisetshenziswa.Fingqa izizathu ezingenza kube mnyamaUkukhanya kwe-LED, okungeyona into engaphezu kwamaphuzu amathathu alandelayo.

1.IDrayivu yonakele

Ubuhlalu besibani se-LED buyadingeka ukuze kusebenze ku-voltage ephansi ye-DC (ngaphansi kuka-20V), kodwa amandla ethu avamile ama-mains ama-AC high voltage (AC 220V).Ukuze siguqule amandla kagesi abe namandla adingwa ubuhlalu besibani, sidinga idivayisi ebizwa ngokuthi “ukunikezwa kwamandla okushayela amanje kwe-LED”.

Ngokwethiyori, inqobo nje uma amapharamitha omshayeli efanisa ipuleti lobuhlalu lwesibani, linganikwa amandla ngokuqhubekayo futhi lisetshenziswe ngokujwayelekile.Ingaphakathi lomshayeli liyinkimbinkimbi.Ukwehluleka kwanoma iyiphi idivayisi (efana ne-capacitor, rectifier, njll.) kungase kubangele ukuguqulwa kwe-voltage ephumayo, bese kubangele ukuthi isibani sifiphale.

Ukulimala komshayeli yiphutha elivame kakhulu kumalambu e-LED.Ngokuvamile ingaxazululwa ngemva kokufaka umshayeli.

2.I-LED ishile

I-LED ngokwayo yakhiwe ngobuhlalu besibani ngamunye ngamunye.Uma eyodwa noma ingxenye yazo ingakhanyi, nakanjani isibani sonke simnyama.Ubuhlalu besibani buvamise ukuxhunywa ngochungechunge bese buhambisana - ngakho-ke uma ubuhlalu besibani bushiswa, iqoqo lobuhlalu besibani lingase lingakhanyi.

Kunamabala amnyama asobala ebusweni bobuhlalu besibani obushile.Yithole, uyixhume ngemuva ngocingo futhi uyijikelezise;Noma ubuhlalu besibani obusha bungaxazulula inkinga.

Led ngezikhathi ezithile ashiswe eyodwa, kungase kube ngenhlanhla.Uma ushisa kaningi, kufanele ucabangele inkinga yedrayivu - okunye ukubonakaliswa kokuhluleka kwedrayivu ukushisa ubuhlalu besibani.

3.Ukunciphisa ukukhanya kwe-LED

Okubizwa ngokuthi ukubola kokukhanya ukuthi ukukhanya kwe-illuminant kuya phansi nangaphansi - okusobala kakhulu kumalambu e-incandescent kanye ne-fluorescent.

Isibani se-LED asikwazi ukugwema ukubola kokukhanya, kodwa isivinini saso sokubola sihamba kancane, futhi ngokuvamile kunzima ukubona ushintsho ngeso lenyama.Kodwa-ke, akukhiphi ukuthi i-led yekhwalithi ephansi, noma ipuleti lobuhlalu lokukhanya eliphansi, noma ngenxa yezici eziqondile ezifana nokungashisi kahle ukushisa, isivinini sokubola kokukhanya kwe-LED siyashesha.
