Sithini isisombululo se-LED luminaire strobe
Okwangoku, ukuba izibane ze-LED ezisetyenziswa rhoqo ngakumbi nangakumbi zisebenzisa umbane we-DC rhoqo, ngokwethiyori kunokwenzeka ukuphumeza ukukhanyisa rhoqo ngaphandle kokuqhwanyaza. Kodwa eneneni, ngenxa yokunqongophala kwemigangatho yoshishino kunye nokhuphiswano oluqatha nolungalunganga lwentengiso, imarike igcwele izibane ezikumgangatho ophantsi we-LED, ngakumbi izibane ze-LED zamandla aphantsi, nazo zineengxaki ze-stroboscopic. Ukuze ufumane umthombo ococekileyo okhoyo ngoku, i-LED drive power supply isitshixo sokuqinisekisa ukuba ukukhanya kwe-LED akufihli. Okwangoku, umbane we-LED unokuhlangabezana ngokupheleleyo nemfuneko yokungafihli. Kukho malunga neendlela ezimbini:
Okokuqala, yandisa imveliso ye-electrolytic capacitor: Le ndlela inokuthi ifunxe inxalenye ye-AC ripple, kodwa iimvavanyo ezihambelanayo zibonise ukuba xa i-ripple ilawulwa phakathi koluhlu oluthile (10%), kunzima ukuyinciphisa ngakumbi, ngaphandle kokuba i-electrolysis. iyanda. Iindleko ze-capacitors azikwazi ukupheliswa ngokupheleleyo ngenye indlela.
Okwesibini, yamkela isisombululo esinamanqanaba amabini: oko kukuthi, ngesiseko sombane okhoyo ozimeleyo, ukongeza unikezelo lwamandla lwe-DC kwinqanaba lokuqala kunokuphelisa ngokupheleleyo impembelelo ye-AC ripple, kunye nemilinganiselo yombane iya kuhlangabezana nemigangatho yokuqinisekisa. Nangona kunjalo, iindleko zenkqubo ziye zanda kwinqanaba elithile, kwaye kuyimfuneko yokongeza iitshiphusi zolawulo lwamandla kunye nezinye iisekethe ze-peripheral.
