Abubuwan da za a lura da su a cikin dimming nisa bugun bugun jini
1. Zaɓin mitar bugun bugun jini: Saboda LED ɗin yana cikin saurin sauyawa, idan mitar aiki ya yi ƙasa sosai, idon ɗan adam zai ji daɗi. Domin yin cikakken amfani da abin da ya rage na gani na idon ɗan adam, mitar aikinsa ya kamata ya zama sama da 100Hz, zai fi dacewa 200Hz.
2. Kawar da ihun da ke haifarwa ta hanyar dimming: Duk da cewa idon ɗan adam ba zai iya gane shi sama da 200Hz ba, shi ne kewayon jin kunnen ɗan adam har zuwa 20kHz. A wannan lokacin, zaku iya jin ƙaramar murya. Akwai hanyoyi guda biyu don magance wannan matsalar. Daya shine ƙara mitar sauyawa zuwa fiye da 20kHz da tsalle daga kewayon jin ɗan adam. Amma yawan mita kuma zai haifar da wasu matsaloli, saboda tasirin sifofin parasitic daban-daban, yanayin bugun bugun jini (gefuna na gaba da baya) za su lalace. Wannan yana rage daidaiton dimming. Wata hanya kuma ita ce nemo na'urar mai sauti da kuma magance ta. A gaskiya ma, babban na'urar da ke samar da sauti shine yumbu capacitor a fitarwa, saboda yumbu capacitors yawanci ana yin su ne da manyan yumbu masu mahimmanci na dielectric, wanda ke da halayen piezoelectric. Karkashin aikin bugun bugun 200Hz, zai haifar da girgizar injin da sauti. Maganin shine a yi amfani da tantalum capacitors maimakon. Duk da haka, babban ƙarfin wutar lantarki tantalum capacitors yana da wuya a samu, kuma farashin yana da tsada sosai, wanda zai kara wasu farashi.
