Nui nā ʻano o ka lako mana LED.ʻOkoʻa ka maikaʻi a me ke kumukūʻai o nā lako mana like ʻole.ʻO kēia kekahi o nā mea nui e pili ana i ka maikaʻi o ka huahana a me ke kumukūʻai.Hiki ke hoʻokaʻawale ʻia ka lako mana LED i ʻekolu mau ʻāpana, ke hoʻololi ʻana i ke kumu o kēia manawa, ka lako mana IC linear, a me ka hoʻolako ʻana i ka mana kūʻē-capacitance step-down.
1. Hoʻohana ka hoʻololi ʻana i ke kumu hoʻololi e hoʻololi i ka volta kiʻekiʻe i ka uila haʻahaʻa, a hana i ka hoʻoponopono ʻana a me ka kānana ʻana e hoʻopuka i kahi kaha haʻahaʻa haʻahaʻa pololei.Hoʻokaʻawale ʻia ke kumu hoʻololi i kēia manawa i ka lako mana kaʻawale a me ka lako mana ʻole.ʻO ka hoʻokaʻawale ʻana e pili ana i ka hoʻokaʻawale ʻana o ka puka kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a he kiʻekiʻe loa ka palekana, no laila ʻaʻole kiʻekiʻe ka koi no ka insulation o ka pūpū.ʻOi aku ka maikaʻi o ka palekana ʻaʻole i hoʻokaʻawale ʻia, akā haʻahaʻa ke kumukūʻai.Hoʻohana nā kukui hoʻopakele ikehu kuʻuna i kahi lako mana kūʻokoʻa ʻole a hoʻohana i ka pūpū plastik insulated no ka pale.ʻOi aku ka kiʻekiʻe o ka palekana o ka mana hoʻololi (ʻo ka mea maʻamau ka haʻahaʻa haʻahaʻa haʻahaʻa), a paʻa ka hana.ʻO ka hemahema, he paʻakikī ke kaapuni a he kiʻekiʻe ke kumukūʻai.ʻO ka lako mana hoʻololi he ʻenehana makua a me ka hana paʻa, a ʻo ia ka mana nui no ka kukui LED.
2. Hoʻohana ka mana IC Linear i hoʻokahi IC a i ʻole IC he nui e puʻunaue i ka uila.He liʻiliʻi nā ʻano o nā ʻāpana uila, ka mana mana a me ka hoʻolako ʻana i ka mana he kiʻekiʻe loa, ʻaʻohe pono electrolytic capacitor, ola lōʻihi a haʻahaʻa haʻahaʻa.ʻO ka hemahema, ʻaʻole i hoʻokaʻawale ʻia ka puka makani kiʻekiʻe, a he stroboscopic, a pono e pale ʻia ka pā i ka uila.Hoʻohana nā mea āpau i nā lako mana IC linear i ka mākeke e ʻōlelo nei ʻaʻohe capacitors electrolytic a me ke ola lōʻihi loa.Loaʻa i ka mana mana IC ka hilinaʻi kiʻekiʻe, ka maikaʻi kiʻekiʻe a me nā pono haʻahaʻa haʻahaʻa, a he mana mana LED kūpono i ka wā e hiki mai ana.
3. Hoʻohana ka RC step-down power supply i ka capacitor e hāʻawi i ka hoʻokele o kēia manawa ma o kāna hoʻouka ʻana a me ka hoʻokuʻu ʻana.He maʻalahi ke kaapuni, he haʻahaʻa ke kumukūʻai, akā maikaʻi ʻole ka hana, a maikaʻi ʻole ke kūpaʻa.He mea maʻalahi loa ka puhi ʻana i ka LED i ka wā e loli ai ka puʻupuʻu grid, a ʻo ka hoʻopuka he kiʻekiʻe-voltage ʻaʻole kaʻawale.ʻO ka pūpū pale pale.ʻO ke kumu haʻahaʻa haʻahaʻa a me ke ola pōkole, kūpono wale nō no nā huahana haʻahaʻa haʻahaʻa (ma loko o 5W).No nā huahana me ka mana kiʻekiʻe, ʻoi aku ka nui o ka manawa hoʻopuka, a ʻaʻole hiki i ka capacitor ke hāʻawi i kēia manawa nui, i ʻole e maʻalahi ke puhi ʻana.Eia kekahi, aia ka ʻāina i nā koi no ka mana o nā kukui mana kiʻekiʻe, ʻo ia hoʻi, ʻo ka mea mana ma luna o 7W e koi ʻia e ʻoi aku ka nui ma mua o 0.7, akā ʻoi aku ka lōʻihi o ka loaʻa ʻana o ka mana kūʻē-capacitance step-down. 0.2-0.3), no laila, ʻaʻole pono e hoʻohana ʻia nā huahana mana kiʻekiʻe RC.Ma ka mākeke, kokoke i nā huahana haʻahaʻa haʻahaʻa me nā koi haʻahaʻa e hoʻohana i nā lako mana RC step-down, a ʻo kekahi mau huahana haʻahaʻa haʻahaʻa, hoʻohana pū kekahi i nā lako mana RC step-down.
