ʻIke ʻike o ka ʻenehana cathode maʻamau LED

Ma hope o nā makahiki o ka hoʻomohala ʻana, ua hoʻokumu ʻia ka hōʻike LED anode maʻamau i kahi kaulahao ʻoihana paʻa, i hāpai i ka hoʻolaha ʻana o ka hōʻike LED. Eia nō naʻe, loaʻa iā ia nā hemahema o ke kiʻekiʻe kiʻekiʻe o ka pale kino wela a me ka hoʻohana mana nui. Ma hope o ka puka ʻana mai o ka ʻenehana cathode LED hōʻike mana mana, ua huki nui ʻia i ka mākeke hōʻike LED. Hiki i kēia mana lako hana ke hoʻokō i ka hoʻopakele ikehu kiʻekiʻe loa o 75%, no laila he aha ka ʻenehana cathode LED hōʻike mana? He aha nā mea maikaʻi o kēia ʻenehana?

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 no ka hōʻike LED. Hāʻawi kaʻawale ʻia ʻo B (ʻulaʻula, ʻōmaʻomaʻo, uliuli), a ua puʻunaue pololei ʻia ke ʻano a me ka uila i nā pahu kukui R, G, a me B, no ka mea, ʻo nā pahu kukui R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli) pono ka mea maikaʻi loa. Volta hana a ʻAʻole like nā au, no laila e hele ke au i 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 hoʻemi ʻia ke kū'ē kūloko o ka conduction.

 

2.He aha ka ʻokoʻa ma waena o ka cathode maʻamau / anode maʻamau LED hōʻike?

①. Nā ʻano hana mana like ʻole:

ʻO ke ʻano hoʻolako mana cathode maʻamau, ʻo ia ke hele mua ʻana i nā pahu kukui, a laila i ka electrode maikaʻi ʻole o ka IC, no laila e hoʻemi ʻia ka hāʻule o ka uila i mua, a hoʻemi ʻia hoʻi ke kūpaʻa kūloko o ka conduction.

 

ʻO ka anode maʻamau, ʻo ia ke kahe ʻana o kēia manawa mai ka papa PCB i nā pahu kukui, a hāʻawi i ka mana iā R, G, a me B (ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli) like ʻole, ʻo ia ka mea e nui ai ka hāʻule ʻana o ka uila i mua o ke kaapuni.

②. ʻOkoʻa ka volta hoʻolako mana:

ʻO ka cathode maʻamau, e hāʻawi kaʻawale ia i kēia manawa a me ka uila iā R, G, B (ʻulaʻula, ʻōmaʻomaʻo, uliuli). He ʻokoʻa nā koi o nā kukui ʻulaʻula, ʻōmaʻomaʻo, a me ka polū. ʻO ka volta o ke kukui ʻulaʻula ma kahi o 2.8V, a ʻo ka volta o nā kukui kukui uliuli a me ka ʻōmaʻomaʻo ma kahi o 3.8V. Hiki i kēia mana mana ke hoʻokō i ka mana kūpono a me ka hoʻohana haʻahaʻa. , ʻO ka wela i hana ʻia e ka hōʻike LED i ka wā o ka hana he haʻahaʻa loa.

 

ʻO ka lā maʻamau ka hāʻawi ʻana i kahi voli kiʻekiʻe ma mua o 3.8V (e like me 5V) iā R, G, a me B (ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli) e hāʻawi i kahi lako mana hui. I kēia manawa, ʻo ka ʻulaʻula, ka ʻōmaʻomaʻo, a me ka ʻulaʻula uila i hui pū ʻia me 5V. Eia nō naʻe, ʻoi aku ka haʻahaʻa o ka volta hana maikaʻi loa o nā kukui ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli ma mua o 5V. Wahi a ka mana mana P = UI, i ka wā e mau ai ka manawa, ʻoi aku ka kiʻekiʻe o ka volta, ʻoi aku ka kiʻekiʻe o ka mana, ʻo ia ʻO ka ʻoi aku ka nui o ka hoʻohana ʻana i ka mana, i ka manawa like, e hoʻohua pū ka hōʻike LED i ka wela i ka wā 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 hoʻemi i ka wela a me ka piʻi haʻahaʻa o ka wela i ka wā o ka hana. Ma lalo o nā kūlana maʻamau, ʻo ka mahana o ka pale anuanu ma kahi o 20°C haʻahaʻa ma mua o ka hōʻike LED waho maʻamau o ke kumu hoʻohālike i ke kūlana kaulike keʻokeʻo a i ka wā e pāʻani ana i ke wikiō. No nā huahana me nā kikoʻī like a me ka ʻōlinolino like, ʻoi aku ka mahana o ka pale cathode LED ma mua o 20 degere haʻahaʻa ma mua o ka huahana hōʻike LED anode maʻamau, a ʻo ka hoʻohana ʻana i ka mana he 50% haʻahaʻa ma mua o ka maʻamau anode LED hōʻike huahana. maluna.

 

ʻO ke kiʻekiʻe kiʻekiʻe o ka pale hōʻike LED a me ka hoʻohana nui ʻana i ka mana ke 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 nā huahana cathode maʻamau i ka ʻenehana mana lako mana, e pili ana i nā hiʻohiʻona photoelectric like ʻole o ka LED ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli, me ka hōʻike IC akamai a me ka ʻōnaehana hoʻokele a me ke ʻano kūʻokoʻa kūʻokoʻa, e hoʻokaʻawale pololei i nā volta like ʻole no nā LED a me nā kaʻa kaʻa e hana i ka huahana. ʻO nā huahana like ma ka mākeke e mālama ma kahi o 40% o ka uila!

 

②. Hāʻawi ka mālama ola maoli i nā kala maoli:

Hiki i ke ala kaʻa kaʻa cathode LED maʻamau ke hoʻomalu pono i ka volta, a ʻoiai e hōʻemi ana i ka hoʻohana ʻana i ka mana, hoʻemi ia i ka nui o ka wela. ʻAʻohe o ka nalu nalu o ka LED ma lalo o ka hana mau ʻana, 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 maikaʻi 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 o ka ʻōnaehana.

 

5. He aha ka ulu ʻana o ka ʻenehana cathode maʻamau?

 

ʻO ke kākoʻo ʻana i ka ʻenehana hōʻike cathode LED 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 o ka cathode IC maʻamau, a ʻaʻole nui ka huina holoʻokoʻa, a noho mau ka anode maʻamau i ka 80% Market.

 

ʻO ka holomua lohi o ka ʻenehana cathode maʻamau ma muli o ke kumukūʻai kiʻekiʻe. Ma muli o ka hui pū ʻana o ke kaulahao hoʻolako mua, pono ka cathode maʻamau i ka hui like ʻana ma nā kihi a pau o ke kaulahao ʻoihana e like me nā chips, packaging, a me PCB, a ʻoi aku ke kiʻekiʻe o ke kumukūʻai.

 

I kēia wā o ka koi nui no ka mālama ʻana i ka ikehu, ua lilo ka puka ʻana o ka cathode transparent LED hōʻike i ke kumu kākoʻo o kēia ʻoihana. Eia nō naʻe, aia kahi ala lōʻihi e hele ai e hoʻokō i ka hoʻolaha ākea a me ka noi ʻana ma ke ʻano nui, e koi ana i ka hoʻoikaika pū ʻana o ka ʻoihana holoʻokoʻa. ʻO ka hōʻike LED cathode maʻamau, ʻo ia ke ʻano hoʻomohala o ka mālama ʻana i ka ikehu, pili i ka hoʻohana ʻana i ka uila a me nā kumukūʻai hana. No laila, pili ka mālama ʻana i ka ikehu i nā makemake o nā mea hana hōʻike LED a pili pū kekahi i ka hoʻohana ʻana i ka ikehu aupuni.

 

I ka hoʻoholo ʻana mai ke kūlana o kēia manawa, ʻaʻole e hoʻonui ka cathode LED maʻamau i ka ikehu hoʻōla ʻana i ke kumukūʻai ma mua o ka pale hōʻike maʻamau, a e mālama i nā kumukūʻai i ka hoʻohana hope ʻana, i mahalo nui ʻia e ka mākeke.
