Kungani ukwehla kwe-voltage ye-LED strip kwenzeka futhi singakugwema kanjani?

Lapho usebenza ngamaphrojekthi womugqa we-LED wamandla aphezulu, kungenzeka ukuthi uzibonele mathupha noma wezwa izexwayiso mayelana nokwehla kwamandla kagesi okuthinta imichilo yakho ye-LED. Kuyini ukwehla kwe-voltage ye-LED strip? Kulesi sihloko, sichaza imbangela yakho nokuthi ungakugwema kanjani ukuthi kungenzeki.

Ukwehla kwamandla kagesi komugqa wokukhanya ukuthi ukukhanya kwekhanda nomsila womugqa wokukhanya akuhambisani. Ukukhanya okuseduze nomthombo wamandla kukhanya kakhulu, futhi umsila umnyama kakhulu. Lokhu ukwehla kwe-voltage yomugqa wokukhanya. Ukwehla kwamandla kagesi okungu-12V kuzovela ngemva kwamamitha angu-5, futhi24V ukukhanya okukhanyayoizovela ngemuva kwamamitha ayi-10. Ukwehla kwe-voltage, ukukhanya komsila womugqa wokukhanya akuphakeme kangako njengangaphambili.

Ayikho inkinga yokwehla kwamandla kagesi ngamalambu anamandla kagesi angu-220v, ngoba uma iphezulu i-voltage, iyancipha amandla amanje kanye nokwehla kwamandla kagesi amancane.

Umugqa wokukhanya wamanje ophansi we-voltage ephansi ungaxazulula inkinga yokwehla kwe-voltage yomugqa wokukhanya, idizayini yamanje ye-IC, ubude obengeziwe bomugqa wokukhanya bungakhethwa, ubude bomugqa wokukhanya oqhubekayo wamanje ngokuvamile bungamamitha ayi-15-30, eyodwa. Ukunikezwa kwamandla okuphelile, ukukhanya kwekhanda nomsila kuyahambisana.

Indlela engcono kakhulu yokugwema ukwehla kwe-voltage ye-LED strip ukuqonda imbangela yayo - umthamo omningi ogeleza ngethusi elincane kakhulu. Unganciphisa okwamanje ngokuthi:

1-Ukunciphisa ubude bomugqa we-LED osetshenziswa ngokuphakelwa kwamandla ngakunye, noma ukuxhuma amandla amaningi kumugqa ofanayo we-LED ezindaweni ezihlukene.

2-Ukukhetha i-24V esikhundleni sokuthi12V isibani se-LED strip(imvamisa ukukhanya okufanayo okukhiphayo kodwa uhhafu wamanje)

3-Ukukhetha isilinganiso samandla esiphansi

4-Ukwandisa i-wire gauge yezintambo zokuxhuma

Kunzima ukukhulisa ithusi ngaphandle kokuthenga amalambu amasha e-LED, kodwa qiniseka ukuthola isisindo sethusi esisetshenziswa uma ucabanga ukuthi ukwehla kwamandla kagesi kungaba yinkinga.Xhumana nathi futhi sizokunikeza isisombululo esanelisayo!
