Ma hope o nā makahiki o ka hoʻomohala ʻana, ua hoʻokumu ka hōʻike LED anode maʻamau i kahi kaulahao ʻoihana paʻa, kahi i alakaʻi ai i ka hoʻolaha ʻana o ka hōʻike LED.Eia nō naʻe, loaʻa iā ia nā drawbacks, ka wela o ka pale a me ka hoʻohana mana nui.Ma hope o ka ʻike ʻia ʻana o ka ʻenehana cathode LED hōʻike mana, 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 lako mana o ka hōʻike LED cathode maʻamau?He aha nā mea maikaʻi o kēia ʻenehana?
He aha nā mea maikaʻi o ka ʻenehana lako mana o ka hōʻike LED cathode maʻamau
1. He aha ka hōʻike LED cathode maʻamau?
ʻO ka "cathode maʻamau" e pili ana i ke ʻano hana mana cathode maʻamau.ʻO ka ʻoiaʻiʻo, he ʻenehana mālama ola kēia no nā hōʻike LED.E pili ana i ka hoʻohana ʻana i ka cathode maʻamau e mana i kahi hōʻike LED.Hoʻokaʻawale ʻo B (ʻulaʻula, ʻōmaʻomaʻo, ʻulaʻula) i ka lako mana, a puʻunaue pololei i ke ʻano a me ka uila o nā pahu kukui R, G, B, no ka mea, pono nā kukui kukui R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli) i ka hana maikaʻi loa. Volta, a he okoa ke au, No laila, e hele mua ke au i ke kukui kukui, a laila e hiki i ka pole ino o ka IC, e hoemi ana i ka kulu uila i mua a e hoemi i ka conduction kūloko.
2. He aha ka ʻokoʻa ma waena o ka cathode maʻamau a me nā hōʻike LED anode maʻamau?
①.Nā ʻano hana lako mana like ʻole:
ʻO ke ala hoʻolako mana cathode i hoʻohana mau ʻia ʻo ia ke hele mua ʻana i ka pahu kukui a hiki i ka pole maikaʻi ʻole o ke kaapuni i hoʻohui ʻia, no laila e liʻiliʻi ka hāʻule o ka uila i mua a e liʻiliʻi ke kū'ē.
ʻO ka anode maʻamau ke kahe o kēia manawa mai ka papa PCB i nā pahu kukui, a hāʻawi like i ka mana iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli), i nui aʻe ka hāʻule o ka uila i mua o ke kaapuni.
②.ʻOkoʻa ka volta hoʻolako mana:
Cathode maʻamau, hoʻolako i kēia manawa a me ka uila no R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli), kēlā me kēia.ʻO nā LED ʻulaʻula, ʻōmaʻomaʻo a me nā ʻulaʻula he ʻokoʻa nā koi uila.ʻO ka volta o nā pahu kukui ʻulaʻula e pili ana i 2.8V, a ʻo ka volta o nā kukui kukui uliuli a me ka ʻōmaʻomaʻo e pili ana i 3.8V, hiki i kēia mana mana ke hoʻokō pololei i ka mana a me ka lako mana.Ma muli o nā poho liʻiliʻi, ʻoi aku ka haʻahaʻa o ka wela i hana ʻia e ka LED i ka wā o ka hana.
Pono ka cathode maʻamau e hāʻawi iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, ʻulaʻula) i kahi mana hoʻohui i ʻoi aku ma mua o 3.8V (e like me 5V).I kēia manawa, ʻo ka uila i loaʻa e ka ʻulaʻula, ka ʻōmaʻomaʻo a me ka uliuli he 5V like ʻole, ʻoiai ʻulaʻula, ʻōmaʻomaʻo, ʻO ka uila hana maikaʻi loa e koi ʻia e nā kukui polū ʻekolu he haʻahaʻa ma mua o 5V.Wahi a ka mana mana P=UI, ma lalo o nā kūlana o kēia manawa, ʻoi aku ka kiʻekiʻe o ka volta, ʻoi aku ka nui o ka mana, ʻo ia hoʻi, ʻoi aku ka nui o ka hoʻohana ʻana i ka mana, ʻoiai ke hana nei ka hōʻike LED Hoʻonui ʻia ka wela ma ke kaʻina hana.
3. No ke aha i emi ai ka wela o ka cathode LED maʻamau?
ʻO ke ʻano hana mana cathode maʻamau maʻamau o ka pale anuanu e hana i ke kaʻina hana hōʻike LED e hoʻoemi i ka wela a me ka piʻi ʻana o ka mahana.Ma lalo o nā kūlana maʻamau, i ka wā o ke kaulike keʻokeʻo a me ka pāʻani wikiō, ʻo ka mahana o ka pale anuanu ma kahi o 20 ° C haʻahaʻa ma mua o ka hōʻike LED waho maʻamau o ke ʻano hoʻohālike.Ma lalo o nā kikoʻī like a me ka ʻālohilohi like, ʻoi aku ka mahana o ka pale cathode LED ma mua o 20 degere ma mua o nā huahana hōʻike anode LED maʻamau, a ʻo ka hoʻohana ʻana i ka mana he 50% haʻahaʻa ma mua o nā huahana hōʻike anode LED maʻamau.
ʻO ke kiʻekiʻe kiʻekiʻe o ka pale hōʻike LED a me ka hoʻohana nui ʻana i ka mana i mau ke kumu nui e pili ana i ke ola lawelawe o ka pale hōʻike LED.Hiki i ka "hōʻike LED cathode maʻamau" ke hoʻoponopono i kēia mau pilikia ʻelua.
4. He aha nā mea maikaʻi o nā hōʻike LED cathode maʻamau?
e mālama pono i ka ikehu:
Hoʻohana nā huahana cathode maʻamau i ka ʻenehana mana mana kūpono, e like me nā ʻano optoelectronic ʻokoʻa o nā kala kumu ʻekolu o ka ʻulaʻula LED, ʻōmaʻomaʻo a me ka uliuli, i hui pū ʻia me ka ʻōnaehana hōʻike IC naʻauao a me ke ʻano hoʻolaʻa kūʻokoʻa, nā ʻokoʻa ʻokoʻa o ka LED a me ke kaʻa kaʻa kaʻa pololei. i hoʻokaʻawale ʻia, i mea kiʻekiʻe ka hoʻohana ʻana i ka mana o ka huahana.ʻO nā huahana like i ka mākeke e mālama ma kahi o 40%!
②.ʻO ka mālama ʻana i ka ikehu maoli ke kala maoli:
Hiki i ke ala hoʻokele cathode LED maʻamau ke hoʻomalu pono i ka volta, ʻoiai e hōʻemi ana i ka hoʻohana ʻana i ka mana a me ka hana wela, ʻaʻole e neʻe ka nalu o ka LED i ka wā e hana mau ai, a hiki ke hōʻike ʻia ke kala maoli!
③.ʻO ka mālama ʻana i ka ikehu maoli e lawe mai i ka lōʻihi o ke ola:
Hoʻemi ʻia ka hoʻohana ʻana i ka ikehu, hoʻemi nui ʻia ka piʻi ʻana o ka wela o ka ʻōnaehana, hoʻemi maikaʻi ʻia ka hopena o ka pōʻino LED, hoʻomaikaʻi ʻia ka paʻa a me ka hilinaʻi o ka ʻōnaehana hōʻike holoʻokoʻa, a hoʻonui nui ʻia ke ola lawelawe o ka ʻōnaehana.
5. He aha nā ʻano o nā ʻenehana maikaʻi ʻole maʻamau?
E pili ana i nā ʻenehana hōʻike LED cathode maʻamau e like me nā LED, nā lako mana, a me nā IC hoʻokele, ʻaʻole ia e like me ke ʻano o ke kaulahao ʻoihana Ram LED.Eia kekahi, ʻaʻole piha ka moʻo IC cathode maʻamau, a ʻaʻole nui ka nui o ke kūʻai aku.Noho mau ʻo Ram i ka 80% o ka mākeke.
ʻO ke kumu nui o ka hoʻomohala lohi o ka ʻenehana cathode maʻamau i kēia manawa ʻo ke kumu kūʻai kiʻekiʻe.Ma ke kumu o ka hui pū ʻana o ke kaulahao hoʻolako mua, pono ka cathode maʻamau i ka hui like ʻana ma nā ʻaoʻao a pau o ke kaulahao ʻoihana e like me nā chips, packaging, a me nā PCB, a he kiʻekiʻe ke kumukūʻai.
I kēia au o ke koi kiʻekiʻe loa no ka mālama ʻana i ka ikehu, ʻo ka puka ʻana mai o ka hōʻike LED ʻike maikaʻi ʻole i lilo i kumu kākoʻo o 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 nui, a koi ʻia nā hana hui o ka ʻoihana holoʻokoʻa.ʻO ka hōʻike LED cathode maʻamau e pili ana i ka hoʻohana ʻana i ka ikehu uila a me nā kumukūʻai hana, ʻo ia ke ʻano hoʻomohala o ka mālama ʻana i ka ikehu.No laila, pili ka mālama ʻana i ka ikehu a me ka hoʻemi ʻai ʻana i ka makemake o nā mea hana hōʻike LED a me ka hoʻohana ʻana i ka ikehu aupuni.
Ma ka hoʻoholo ʻana mai ke kūlana o kēia manawa, ʻaʻole e hoʻonui nui ʻia ke kumukūʻai cathode LED maʻamau i ka hoʻohālikelike ʻana me ka hōʻike kuʻuna, a e mālama pū i nā kumukūʻai i ka wā e hiki mai ana, i loaʻa maikaʻi e ka mākeke.
