Ma hope o nā makahiki o ka hoʻomohala ʻana, ua hoʻokumu ʻo LED anode maʻamau i kahi kaulahao ʻoihana paʻa, e hoʻokau i ka kaulana o nā hōʻike LED. Eia nō naʻe, loaʻa iā ia nā hemahema o ka wela o ka pale kiʻekiʻe a me ka hoʻohana mana nui. Ma hope o ka puka ʻana o ka ʻenehana cathode LED hōʻike mana lako, ua huki nui ʻia i ka mākeke hōʻike LED. Hiki i kēia ʻano mana lako ke hoʻokō i ka nui o ka mālama ʻana i ka ikehu o 75%. No laila he aha ka ʻenehana cathode LED hōʻike mana? He aha nā mea maikaʻi o kēia ʻenehana?
1. He aha ka LED cathode maʻamau?
ʻO ka "cathode maʻamau" e pili ana i ke ʻano hana mana cathode maʻamau, ʻo ia ka ʻenehana mālama ola no nā pale hōʻike LED. 'O ia ho'i ka ho'ohana 'ana i ke ala cathode ma'amau no ka ho'ohana 'ana i ka pale hō'ike LED, 'o ia ho'i, 'o ka R, G, B ('ula'ula, 'ōma'oma'o, uliuli) o nā kukui kukui LED e ho'oka'awale 'ia, a ua ho'oka'awale pololei 'ia ke au a me ka voltage i ka R. , G, B nā lei kukui, no ka mea, he okoa ka volta hana maikai a me keia manawa e pono ai e ka R, G, B (ulaula, omaomao, uliuli). Ma kēia ala, hele mua ka mea i kēia manawa ma nā pahu kukui a laila i ka electrode maikaʻi ʻole o ka IC, e hoʻemi ʻia ka hāʻule o ka uila i mua, a e liʻiliʻi ke kūpaʻa kūloko.
2. He aha ka ʻokoʻa ma waena o ka cathode maʻamau a me nā LED anode maʻamau?
①. Nā ʻano hana lako mana like ʻole:
ʻO ke ʻano hana hoʻolako cathode maʻamau, ʻo ia ka mea e hele mua i ka pahu kukui a laila i ka pole maikaʻi ʻole o ka IC, kahi e hoʻemi ai i ka hāʻule ʻana o ka uila i mua a me ka conduction kūloko kūloko.
ʻO ka anode maʻamau ka holo ʻana o kēia manawa mai ka papa PCB i ka pahu kukui, a hāʻawi i ka mana iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli) like ʻole, kahi e alakaʻi ai i kahi hāʻule nui o ka uila i mua o ke kaapuni.
②. ʻOkoʻa ka mana lako uila:
ʻO ka cathode maʻamau, e hāʻawi i kēia manawa a me ka uila iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli) kaʻawale. ʻOkoʻa nā koi uila o nā kukui kukui ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli. ʻO ke koi uila o nā kukui ʻulaʻula e pili ana i ka 2.8V, a ʻo ke koi ʻana o nā kukui uila uliuli-'ōmaʻomaʻo ma kahi o 3.8V. Hiki i ia lako mana ke hoʻokō i ka mana kūpono a me ka emi ʻana o ka mana, a ʻoi aku ka haʻahaʻa o ka wela i hana ʻia e LED i ka wā hana.
ʻO ka anode maʻamau, ma ka ʻaoʻao ʻē aʻe, hāʻawi iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, ʻulaʻula) i kahi voli kiʻekiʻe ma mua o 3.8V (e like me 5V) no ka lako mana hui. I kēia manawa, ʻo ka volta i loaʻa e ka ʻulaʻula, ka ʻōmaʻomaʻo a me ka uliuli he 5V i hui pū ʻia, akā ʻoi aku ka haʻahaʻa o ka volta hana maikaʻi loa e koi ʻia e nā pahu kukui ʻekolu ma mua o 5V. Wahi a ka mana mana P=UI, ke hoʻololi ʻole ke ʻano o kēia manawa, ʻoi aku ka kiʻekiʻe o ka volta, ʻoi aku ka kiʻekiʻe o ka mana, ʻo ia hoʻi, ʻoi aku ka nui o ka hoʻohana mana. I ka manawa like, e hoʻonui ka LED i ka wela i ka wā o ka hana.
ʻO kaʻO ke ao holoʻokoʻa ʻekolu-hanauna waho LED hoʻolaha pale i hoʻomohala ʻia e XYGLED， hoʻohana i ka cathode maʻamau. Ke hoʻohālikelike ʻia me nā diodes ʻulaʻula 5V, ʻōmaʻomaʻo, a me ka polū, ʻo ka pole maikaʻi o ka chip LED ʻulaʻula he 3.2V, ʻoiai ʻo nā LED ʻōmaʻomaʻo a me ka uliuli he 4.2V, e hōʻemi ana i ka hoʻohana ʻana i ka mana ma ka liʻiliʻi loa 30% a hōʻike i ka ikehu maikaʻi loa. ka ho'ōla a me ka ho'ēmi 'ana i ka hana.
3. No ke aha i emi ai ka wela o ka hōʻike LED cathode?
ʻO ke ʻano hana mana cathode maʻamau o ka pale anuanu e hoʻoemi i ka wela a me ka piʻi haʻahaʻa o ka mahana i ka wā e hana ai. Ma lalo o nā kūlana maʻamau, i ke kūlana kaulike keʻokeʻo a i ka wā e pāʻani ana i nā wikiō, ʻo ka mahana o ka pale anuanu ma kahi o 20 ℃ haʻahaʻa ma mua o ka hōʻike LED waho maʻamau o ke ʻano hoʻohālike. No nā huahana o nā kikoʻī like a me ka ʻālohilohi like, ʻoi aku ka mahana o ka pale cathode maʻamau ma mua o 20 degere haʻahaʻa ma mua o nā huahana hōʻike anode maʻamau, a ʻoi aku ka nui o ka mana ma mua o 50% haʻahaʻa ma mua o kēlā. o nā huahana hōʻike LED anode maʻamau.
ʻO ka wela nui a me ka hoʻohana ʻana i ka mana o ka hōʻike LED ʻo ia nā kumu nui e pili ana i ke ola lawelawe o nā huahana hōʻike LED, a ʻo ka "hōʻike LED cathode maʻamau" hiki ke hoʻoponopono maikaʻi i kēia mau pilikia ʻelua.
4. He aha nā mea maikaʻi o ka hōʻike LED cathode maʻamau?
①. ʻO ka hāʻawi mana pololei ka mālama ʻana i ka ikehu:
Hoʻohana ka huahana cathode maʻamau i ka ʻenehana mana lako mana, e pili ana i nā hiʻohiʻona photoelectric like ʻole o nā kala kumu ʻekolu o LED ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli, a ua hoʻolako ʻia me kahi ʻōnaehana hōʻike IC naʻauao a me kahi ʻāpana kūʻokoʻa kūʻokoʻa e hoʻokaʻawale pololei i nā voltages like ʻole. i ka LED a me ke kaapuni kaapuni, no laila, e pili ana ka mana o ka huahana ma kahi o 40% haʻahaʻa ma mua o nā huahana like ma ka mākeke!
②. Hāʻawi ka mālama ola maoli i nā kala ʻoiaʻiʻo:
Hiki i ke ala kaʻa kaʻa cathode LED maʻamau ke hoʻomalu pono i ka volta, e hōʻemi ana i ka hoʻohana ʻana i ka mana a me ka hana wela. ʻAʻole holo ka nalu o ka LED ma lalo o ka hana mau, a hōʻike paʻa ʻia ke kala maoli!
③. ʻO ka mālama ʻana i ka ikehu maoli ke ola lōʻihi:
Hoʻemi ʻia ka hoʻohana ʻana i ka ikehu, a laila e hōʻemi nui i ka piʻi ʻana o ka mahana o ka ʻōnaehana, e hōʻemi pono ana i ka hopena o ka pōʻino LED, hoʻomaikaʻi i ka paʻa a me ka hilinaʻi o ka ʻōnaehana hōʻike holoʻokoʻa, a hoʻonui nui i ke ola ʻōnaehana.
5. He aha ka ulu ʻana o ka ʻenehana cathode maʻamau?
ʻO nā huahana kākoʻo e pili ana i ka ʻenehana hōʻike LED cathode maʻamau, e like me ke LED, ka lako mana, ka mea hoʻokele IC, a me nā mea ʻē aʻe, ʻaʻole like me ke ʻano o ke kaulahao ʻoihana LED anode maʻamau. Eia kekahi, ʻaʻole i pau ka moʻo cathode IC maʻamau i kēia manawa, a ʻaʻole nui ka leo holoʻokoʻa, ʻoiai ke noho nei ka anode maʻamau i 80% o ka mākeke.
ʻO ke kumu nui o ka holomua lohi o ka ʻenehana cathode maʻamau ke kumu kūʻai kiʻekiʻe. Ma muli o ka hui pū ʻana o ke kaulahao hoʻolako kumu, pono ka cathode maʻamau i ka hui like ʻana ma nā ʻaoʻao āpau o ke kaulahao ʻoihana e like me nā chips, packaging, PCB, etc., he kumu kūʻai.
I kēia wā o nā kelepona kiʻekiʻe no ka mālama ʻana i ka ikehu, ua lilo ka puka ʻana o nā pale hōʻike LED cathode maʻamau i ke kumu kākoʻo i hahai ʻia e kēia ʻoihana. Eia nō naʻe, aia kahi ala lōʻihi e hele ai e hoʻokō i ka hoʻolaha ākea a me ka hoʻohana ʻana ma ke ʻano ʻoi aku ka nui, kahi e koi ai i ka hoʻoikaika pū ʻana o ka ʻoihana holoʻokoʻa. E like me ke ʻano o ka hoʻomohala ʻana i ka ikehu, ʻo ka pale hōʻike cathode LED maʻamau e pili ana i ka hoʻohana a me nā kumukūʻai hana o ka uila. No laila, pili ka mālama ʻana i ka ikehu i nā makemake o nā mea hoʻohana pale hōʻike LED a me ka hoʻohana ʻana i ka ikehu aupuni.
Mai ke kūlana o kēia manawa, ʻaʻole e hoʻonui nui ʻia ke kumukūʻai o ka cathode LED maʻamau e hoʻōla i ka ikehu, a e mālama ia i nā kumukūʻai ma hope o ka hoʻohana ʻana, i mahalo nui ʻia e ka mākeke.
