ʻO nā voltase maʻamau o nā kaula LED he 12VDC a me 24VDC, a ua like ko lākou mau kumukūʻai. Ke mākaukau ʻoe e kūʻai i nā ʻāpana LED, he nīnau paha kāu, he aha ka ʻokoʻa ma waena o nā ʻāpana 12VDC a me nā ʻāpana 24VDC? ʻO wai kaʻu e koho ai?
Hāʻawi ʻo LEDYi i ka 12VDC a me 24VDC Pākuʻi LED. Ma lalo o nā kūlana maʻamau, ʻaʻole nui loa ka ʻokoʻa ma waena o ka 12VDC LED strip a me ka 24VDC LED strip, ke koho ʻoe i ka lako mana kūpono.
Inā makemake ʻoe i kahi lōʻihi ʻoki pōkole, paipai mākou e koho i kahi kāʻei LED 12VDC. No ke kāʻei LED me ka nui LED like, ʻo ka lōʻihi o ka ʻoki ʻia o ke kāʻei LED 12VDC ʻo ia ka hapalua o ka lōʻihi o ke kāʻei LED 24V. Hāʻawi kēia iā ʻoe i ka maʻalahi e ʻoki i ke kaula LED i ka lōʻihi āu e makemake ai.
Inā makemake ʻoe i kahi holo laina lōʻihi a ʻoi aku ka maikaʻi o ka luminous, makemake mākou e koho i nā ʻāpana LED 24VDC.
Inā makemake ʻoe e aʻo hou e pili ana i nā ʻano ʻenehana, e heluhelu ma lalo no nā ʻokoʻa hou aku.
12VDC LED kaula me ka lōʻihi oki pōkole
ʻO ka hapa nui o nā pahu kukui LED e holo ana ma ka mana 3VDC me ka nānā ʻole inā ua kau ʻia lākou ma kahi kaula 12V a i ʻole kahi kaula 24V. ʻO ka ʻoiaʻiʻo, hiki ke kau ʻia ka puʻupuʻu LED like e hana ana ma kahi kaula 12V ma kahi kaula 24V. ʻO ka mea ʻokoʻa ke ʻano o ka hoʻolālā ʻana o ka circuit circuit.
Hoʻopili ʻia nā ʻāpana LED i nā hui o nā LED. Ka nui o ka
pili ka hui i ka volta o ke kaula. He 12 mau LED ma kahi kaula 3V, a he 24 mau LED a i ʻole 6 mau LED ma kahi kaula 7V, a hiki i 8 mau LED. Aia nā laina i ʻoki ʻia ma waena o nā hui. No laila, ʻoi aku ka liʻiliʻi o kēlā me kēia hui o nā LED, ʻoi aku ka pili o nā laina ʻoki.
No ka laʻana, e ʻike i nā kiʻikuhi o nā ʻāpana 12V a me 24V ma lalo nei.
ʻOi aku ka maikaʻi o ke kaha haʻahaʻa haʻahaʻa 12VDC me nā laina ʻoki kokoke loa inā he nui nā kihi me nā lōʻihi pōkole o kāu kau ʻana. Hiki i kēia ke kōkua i ka hōʻemi ʻana i ka ʻāpana "ʻeleʻele" ma nā kihi.
No ka loaʻa ʻana o ka pono o ka Long Run o ka 24VDC LED strip a me ka pōkole ʻoki ʻoki ʻana o ka 5VDC LED strip, ua hoʻomohala mākou. ʻOki liʻiliʻi LED kaha, 1 LED no ke oki ma 24VDC.
ʻOi aku ka laulā o nā hiʻohiʻona noiʻi ʻo 12V LED strip
Ma ka ʻaoʻao ʻē aʻe, ʻo 12 VDC kahi volta maʻamau, no laila hiki ke hoʻopau ʻia ka hoʻohālikelike ʻana o ka LED i ka pono o nā lako mana hou. No ka laʻana, inā ʻoe e kau ana i nā kukui i loko o kahi kaʻa, hiki ke hoʻopili pinepine ʻia kahi kukui uila 12 VDC LED i ka ʻōnaehana uila. ʻOiai aia kekahi mau ʻokoʻa i kēia, a he mea nui e nānā i kāu ʻōnaehana i kēia manawa ma mua o ka hana ʻana i kahi kūʻai, hiki i nā ʻāpana LED 12V ke hāʻawi i kahi hoʻonā hoʻonohonoho maʻalahi i nā hihia he nui.
24V LED strip, holo laina lōʻihi
Hiki ke holo lō'ihi aku ke ka'a uila ki'eki'e me ka loa'a 'ole o ka hopena o ka hā'ule uila.
He aha ka hāʻule uila?
ʻO ka hāʻule ʻana o ka Voltage ke kumu e nalowale ai ka ikaika o nā kaula LED i ka lōʻihi. E ʻālohilohi nā LED ma ka hoʻomaka o ke kāʻei (kokoke i ka lako mana). ʻO ka ʻokoʻa, ʻo nā LED ma ka hope o ke kāʻei e loaʻa i kahi hiʻohiʻona pohihihi.
No ke aha e hāʻule ai ka voltage?
Loaʻa i kēlā me kēia lōʻihi o ka uea kekahi nui o ka pale uila. ʻO ka lōʻihi o ka uwea, ʻoi aku ka nui o ke kūʻē. ʻO ke kūpaʻa uila ke kumu o ka hāʻule ʻana o ka uila, a ʻo ka hāʻule ʻana o ka uila ke kumu e pōʻeleʻele ai kāu mau LED.
No laila, ʻo nā LED ma ka hope o kahi kaula e loaʻa mau ka liʻiliʻi ma mua o nā mea ma ka hoʻomaka. Inā lōʻihi ka lōʻihi o ke kāʻei, e lilo ka hāʻule o ka volta i mea nui i mea e ʻike ʻia ai ka ʻokoʻa o ka mālamalama.
Pehea e hoʻemi ai ka uila kiʻekiʻe i nā hopena o ka hāʻule ʻana o ka voltage?
ʻO ka mea mua, pono ʻoe e hoʻomaopopo pehea e hoʻopili ʻia ai nā ʻāpana āpau ma kahi kaula LED.
ʻO ka hapa nui o nā pahu kukui LED e holo ana ma ka mana 3V DC me ka nānā ʻole inā ua kau ʻia lākou ma kahi kaula 12V a i ʻole kahi kaula 24V. ʻO ka ʻoiaʻiʻo, hiki ke kau ʻia ka puʻupuʻu LED like e hana ana ma kahi kaula 12V ma kahi kaula 24V. ʻO ka mea ʻokoʻa ke ʻano o ka hoʻolālā ʻana o ka circuit circuit.
Hoʻopili ʻia nā ʻāpana LED i nā pūʻulu. Loaʻa i kēlā me kēia hui kekahi mau pahu LED a me kahi pale. Pono e like ka hāʻule ʻana o ka volta holoʻokoʻa ma waena o ka hui me ka nui o ka volta o ke kaula (e nānā i nā kiʻi ma lalo).
A laila, hoʻopaʻa ʻia kēlā me kēia pūʻulu i ka laina like a hoʻonohonoho ʻia ma ka lōʻihi o ke kaula.
I kēia manawa, e makaʻala (ma luna o nā kiʻi) ʻo ka nui o ka hui ma kahi ʻāpana 24V he 7 mau LED ke hoʻohālikelike ʻia me 3 LED wale nō no 12V. E wehewehe au i ke kumu nui o kēia ma lalo nei.
Loaʻa i kēlā me kēia uea kekahi nui o ke kū'ē i ka uila e hoʻokuʻu ʻia ma ia. ʻOi aku ka lōʻihi o ka uwea, ʻoi aku ka nui o ke kūpaʻa (a me ka hāʻule o ka volta). ʻO ka hopena, nui ka nui e hoʻopili i ka kukui LED. Aia ma lalo kahi hiʻohiʻona o ke ʻano o ka hana ʻana ma kahi kaula 12V.
E ʻike ma ke kiʻikuhi ma luna aʻe ua hāʻule ka volta ma waena o nā LED mai 3.0V a i 2.75V.
Ke hoʻololi mākou i 24V, ʻelua mau mea e hōʻemi i ka hāʻule o ka volta.
Ke hoʻopālua ʻia ka volta (12V a 24V), hoʻokaʻawale ʻia ka manawa (ke kānāwai o Ohm P=U * I). ʻO ia ke kumu e hoʻemi ʻia ai ka hāʻule o ka volta mai ka uea lōʻihi e ka hapalua. No laila ma kahi o kahi hāʻule 1V, lilo ia i hāʻule 0.5V.
Hoʻokaʻawale ʻia ka hopena o ka hāʻule 0.5V ma waena o nā ʻāpana kaapuni ʻewalu i koe (hoʻohālikelike ʻia me 4 ma ka 12V).
E ʻike ma aneʻi ua hāʻule wale ka volta ma waena o nā LED i 2.9375V i hoʻohālikelike ʻia me 2.75V me ka 12V strip.
Inā loaʻa iā ʻoe kahi noi e koi ana i ka holo lōʻihi o nā paʻi, pono paha e hoʻohana i nā paʻi 24V. Akā, ʻo nā ʻāpana 24V he palena. Pono paha ʻoe e hoʻohana i nā ʻenehana ʻē aʻe e pani i kāu mau LED mai ka mae ʻana i ka hopena. No ka laʻana, e hoʻohana i kā mākou ʻO nā kāʻei LED o kēia manawa mau loa.
Hiki i ka 24V LED strip ke ʻoi aku ka maikaʻi
Hiki ke ʻoi aku ka maikaʻi o ka voltage kiʻekiʻe.
I kēlā me kēia manawa aia ka volta ma waena o kahi resistor, ʻo ia ka mea e hoʻololi ʻia ka ikehu i ka wela ma kahi o ka māmā. No laila, pono nā mea kū'ē i nā kiʻi i luna, akā he kumu ia o ka ikehu.
| Huina paulele o ke kaula | Voltage ma ka pale pale | % Mana "mauna" ma nā mea pale |
| 5V (1 LED no ka hui) | 2V | 40% |
| 12V (3 LED no ka hui) | 3V | 25% |
| 24V (7 LED no ka hui) | 3V | 12.5% |
He mea maʻalahi ke ʻike i ka pilikia o nā ʻāpana uila kiʻekiʻe me ka liʻiliʻi o ka ikehu. Hoʻohana nā LED i ka ikehu liʻiliʻi ʻaʻole ia e hoʻohui i ka nui no nā mea liʻiliʻi. Akā, ʻo ka ʻokoʻa o ka hoʻohana ʻana i ka mana hiki ke lilo i mea nui no ka lumi holoʻokoʻa a i ʻole nā mea kūʻai aku.
Ua kūkulu mākou kiʻekiʻe-efficiency LED kaula, 8 mau LED no ke oki, a hiki i 190LM/w.
ʻO kēia ka loina like me ka hoʻoili mana kiʻekiʻe-voltage. ʻO ke kiʻekiʻe o ka volta, ʻoi aku ka liʻiliʻi o ke au. Wahi a ke kānāwai o Ohm, ʻo ka hāʻule o ka volta Vpapa=I * R, ka ikehu uila i hoʻololi ʻia i ka wela P=U * I = (I * R) * I = I 2 * ʻO R.
24V LED strip pono emi conductor ana ana
Hoʻoholo ʻia ka mana uila e ka hoohalike P = V * I. No ka mālama ʻana i ka mana like (P), inā piʻi ka uila (V), pono e iho mai ke au (I) i ka huina kūlike.
Inā mālama mākou i ka 48W ma ke ʻano he kumu hoʻohālikelike, pono ka ʻōnaehana 12V i 4 Amps (12V x 4A = 48W), aʻo kahi ʻōnaehana 24V e koi wale i 2 Amps (24V x 2A = 48W).
Ma ka waiho wale ʻana, e huki ka ʻōnaehana 24V LED i ka hapalua o ka nui o kēia manawa e like me ka ʻōnaehana 12V LED e hoʻokō i ka pae mana like.
No ke aha lā i kēiaʻano nui?
ʻO ka nui o kēia manawa, ma mua o ka volta, e hoʻoholo i ka mānoanoa a me ka laulā o nā mea lawe keleawe e pono ai ke hoʻololi i ka mana me ka palekana.
Inā hoʻoikaika ʻia ka nui o ke au ma o kahi mea lawe keleawe liʻiliʻi a haiki paha, e lilo ke kūpaʻa i loko o ka conductor i mea nui a kōkua i ka hāʻule ʻana o ka uila a me ka hana wela. I nā hihia koʻikoʻi loa, hiki i kēia ke alakaʻi i ke ahi uila.
ʻO nā mea ʻē aʻe āpau, hiki i kahi ʻōnaehana LED 24V ke hele me ka hapalua o nā koi conductor uila. Hiki iā ʻoe ke hoʻohana i kā mākou helu helu hāʻule uila no ka hōʻoia ʻana e hoʻohana mau ana ʻoe i nā ana alakaʻi kūpono no kāu mau papahana kāwele LED.
ʻO nā lako mana liʻiliʻi no ka 24V LED strip
E like me ka nui o ka conductor, hoʻoholo ʻia ka nui o ka mana e ka manawa ma mua o ka volta. Hoʻopili pū ʻia kekahi hapa o kēia e ka pilina physics ma waena o ke au uila a me ka nui o ka conductor e pono ai, no ka mea, ʻo ka nui o nā uea kūloko o ka mana lako i loko o ka uwea keleawe.
He mea koʻikoʻi ka nui o ka mana i ka wā e hana ai me nā papahana e like me nā kukui LED ma lalo o nā hale keʻena kahi i loaʻa ai nā pilikia ākea.
Panina
Ke manaʻoʻiʻo nei au ma hope o ka heluhelu ʻana i kēia ʻatikala, ua hiki mai ʻoe a me aʻu i ka manaʻo like ʻoi aku ka maikaʻi o nā 24VDC LED strips ma mua o 12VDC LED strips. Inā hiki, ʻoi aku ka nui ma nā papahana kukui nui, e ʻoluʻolu e hoʻohana i nā ʻāpana LED 24VDC.
Hana ʻo LEDYi i ke ʻano kiʻekiʻe Nā kāʻei LED a me ka neon flex LED. Ke hele nei kā mākou huahana a pau ma nā hale hana ʻenehana kiʻekiʻe e hōʻoia i ka maikaʻi loa. Ma waho aʻe o kēia, hāʻawi mākou i nā koho maʻamau i kā mākou LED strips a me neon flex. No laila, no ke kāʻei LED premium a me ka neon flex LED, hoʻopili iā LEDYi ASAP!
