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 ye-DC ephansi (ngaphansi kuka-20V), kodwa amandla ethu avamile ama-mains yi-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 afana nepuleti 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 isibani ukuthi 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.
