ʻO nā pilikia e ʻike ʻia i ka dimming laula pulse
1. Ke koho ʻana i ke alapine pulse: No ka mea aia ka LED i kahi kūlana hoʻololi wikiwiki, inā haʻahaʻa loa ke alapine hana, e ʻike ka maka o ke kanaka. I mea e hoʻohana piha ai i ke koena hiʻohiʻona ʻike o ka maka kanaka, ʻoi aku ka kiʻekiʻe o kona alapine hana ma mua o 100Hz, ʻoi aku ka maikaʻi o 200Hz.
2. Hoʻopau i ka uē ʻana ma muli o ka pōʻeleʻele: ʻOiai ʻaʻole hiki ke ʻike ʻia ka maka o ke kanaka ma luna o 200Hz, ʻo ia ka laulā o ka lohe pepeiao kanaka a hiki i ka 20kHz. I kēia manawa, lohe paha ʻoe i kahi leo liʻiliʻi. ʻElua ala e hoʻoponopono ai i kēia pilikia. ʻO kekahi e hoʻonui i ka alapine hoʻololi i ʻoi aku ma mua o 20kHz a lele i waho o ka laulā o ka lohe kanaka. Akā ʻo ke alapine kiʻekiʻe e hoʻopilikia i kekahi mau pilikia, ma muli o ka hopena o nā ʻāpana parasitic like ʻole, e hoʻololi ʻia ka nalu pulse (mua a me hope). Hoʻemi kēia i ka pololei o ka dimming. ʻO kekahi ala ʻē aʻe ʻo ka ʻimi ʻana i ka mea kani a hana pū me ia. ʻO ka ʻoiaʻiʻo, ʻo ka mea hoʻoheheʻe leo nui ʻo ia ka capacitor ceramic ma ka hopena, no ka mea, hana maʻamau nā capacitors ceramic i nā ceramics mau dielectric kiʻekiʻe, nona nā hiʻohiʻona piezoelectric. Ma lalo o ka hana o 200Hz pulse, e hoʻopuka i ka haʻalulu mechanical a me ke kani. ʻO ka hopena e hoʻohana i nā capacitor tantalum ma kahi. Eia nō naʻe, paʻakikī ka loaʻa ʻana o nā capacitors tantalum kiʻekiʻe, a he pipiʻi loa ke kumukūʻai, e hoʻonui ai i kekahi mau kumukūʻai.
