Iyini isixazululo se-LED luminaire strobe
Okwamanje, uma izibani ze-LED ezivame ukusetshenziswa kakhulu zisebenzisa amandla kagesi e-DC, ngokombono kungenzeka ukuzuza ukukhanya okungapheli ngaphandle kokucwayiza. Kodwa empeleni, ngenxa yokuntuleka kwamazinga embonini kanye nokuncintisana kwemakethe okuqinile nokungahambi kahle, imakethe igcwele izibani ze-LED ezisezingeni eliphansi, ikakhulukazi izibani ze-LED zamandla aphansi, nazo ezinezinkinga ze-stroboscopic. Ukuze uthole umthombo wamanje ohlanzekile, amandla kagesi e-LED ayisihluthulelo sokuqinisekisa ukuthi ukukhanya kwe-LED akucwayizi. Njengamanje, ugesi we-LED ungahlangabezana ngokugcwele nemfuneko yokungacwayizi. Cishe kunezindlela ezimbili:
Okokuqala, khulisa i-electrolytic capacitor ephumayo: Le ndlela ingakwazi ukumunca ingxenye ye-AC ripple, kodwa ukuhlola okuhlobene kubonise ukuthi uma i-ripple ilawulwa phakathi kwebanga elithile (10%), kunzima ukuyinciphisa ngokuqhubekayo, ngaphandle uma i-electrolysis. iyanda. Izindleko zama-capacitors azikwazi ukuqedwa ngokuphelele ngenye indlela.
Okwesibili, sebenzisa isixazululo esinamazinga amabili: okungukuthi, ngesisekelo samandla akhona angawodwa, ukwengeza ugesi wezinga lokuqala le-DC kungaqeda ngokuphelele umthelela we-AC ripple, futhi imingcele kagesi izophinde ihlangabezane nezindinganiso zesitifiketi. Kodwa-ke, izindleko zohlelo zikhuphuke ngezinga elithile, futhi kuyadingeka ukwengeza ama-chips okuphatha amandla amaningi kanye namasekhethi athile azungezile.
