Aia nā hōʻike LED ma nā wahi a pau i kēia manawa. He ʻulaʻula a ʻālohilohi lākou, e hoʻohui i nā kala i ko mākou ola. Akā ua noʻonoʻo paha ʻoe i ke ʻano o kēia mau hōʻike LED? I kēia lā, e kamaʻilio e pili ana i nā mea nui o nā hōʻike LED - nā lei kukui.
ʻO kekahi o nā mea koʻikoʻi o nā hōʻike LED he mau kukui kukui, ʻo ia ka nui o nā cubes a i ʻole cuboids a loaʻa nā ʻano kikoʻī like ʻole, e like me 3535, 3528, 2835, 2727 (2525), 2121, 1921, 1515, 1010, a pēlā aku. bracket, hoʻopiha ʻia me ke kāpili a maloʻo. ʻO ko lākou mau ʻālohilohi ka mea maʻamau i mua o ka luminous hoʻokahi, a hiki ke kūʻai pololei ʻia nā pine kukui ma kahi papa kaapuni PCB me kahi ili kūʻai.
Loaʻa i nā pahu kukui LED nā ʻano kikoʻī a me nā hiʻohiʻona e hoʻololi i nā hiʻohiʻona noiʻi like ʻole. Ma ke kahua o nā SMD LED i loko, nā kikoʻī kukui kukui maʻamau me 0505, 1010, 1515, 2121, 3528, a me nā mea ʻē aʻe. No ka laʻana, ʻo 0505 ka lōʻihi a me ka laula o ka mea LED he 0.5mm.
ʻO ka wehewehe kikoʻī o nā kikoʻī kukui kukui
ʻO 0.5mm × 0.5mm ka nui metric o nā kukui kukui 0505, a ʻo ka pōkole ʻoihana ʻo 0505;
ʻO ka nui metric o nā pahu kukui 1010 he 1.0mm × 1.0mm, a ʻo ka pōkole ʻoihana ʻo 1010;
ʻO 2.1mm × 2.1mm ka nui metric o nā kukui kukui 2121, a ʻo ka pōkole ʻoihana ʻo 2121;
ʻO 3.5mm × 2.8mm ka nui metric o 3528 kukui kukui, a ʻo ka pōkole ʻoihana ʻo 3528;
ʻO 5.0mm × 5.0mm ka nui metric o nā kukui kukui 5050, a ʻo ka pōkole ʻoihana ʻo 5050.
Nui nā mea hana kukui kukui LED kaulana i ka honua,
Hoʻopili ʻia nā pahu kukui LED ma nā ʻano like ʻole, me ka plug-in pololei, SMD, mana kiʻekiʻe a me nā pahu kukui LED COB. I ka manawa like, he waihoʻoluʻu nā kukui kukui LED, me ka ʻulaʻula, melemele-'ōmaʻomaʻo, melemele, ʻalani, uliuli, poni, ʻulaʻula a keʻokeʻo.
I ka ʻike ʻana i nā pou maikaʻi a maikaʻi ʻole o nā pahu kukui LED, hiki iā mākou ke hoʻokaʻawale iā lākou ma ke kaha ʻana a me ke ʻano. ʻO ka mea maʻamau, e hōʻailona ʻia ka pole maikaʻi ma ke ʻano he kiko liʻiliʻi a i ʻole triangle a puka i waho; ʻoiai ʻaʻohe hōʻailona o ka pole ʻino a ʻoi aku ka pōkole ma mua o ka pou maikaʻi. Inā ʻaʻole hiki ke hoʻoholo ʻia nā pou maikaʻi a maikaʻi ʻole, hiki iā mākou ke hoʻohana i ka multimeter no ka hoʻāʻo ʻana.
He mea koʻikoʻi ke koho ʻana i kahi pahu kukui kukui LED kūpono i ka hoʻomaikaʻi ʻana i ka hana a me ke ola o nā huahana LED. Ke koho ʻana i kahi hōʻailona, pono mākou e noʻonoʻo i nā kumu he nui e hōʻoia i ka hoʻokō ʻana o ka brand i koho ʻia i kā mākou mau koi.
Ma muli o kāna mau palena hoʻolālā, hoʻohana nui ʻia nā pahu kukui LED pololei i nā huahana waho me nā spacings e like me P10, P16, a me P20. Hoʻohana nui ʻia nā peʻa kukui LED ma waho a me loko ma muli o kā lākou hana maʻamau, nā pale metala hiki ke hoʻololi ʻia, a me nā ʻano like ʻole. Inā he P13.33 waho, P10, P8 a me nā spacing ʻē aʻe, a i ʻole P1.875 i loko, P1.667, P1.53, P1.25 a me nā mea liʻiliʻi liʻiliʻi liʻiliʻi, hiki i nā pahu kukui LED i hoʻopaʻa ʻia i ka ʻili ke hoʻokō i nā pono.
Ke hōʻike nei nā manaʻo hoʻomohala o nā pahu kukui modula hōʻike LED i kahi ʻano maikaʻi. Ke alakaʻi ʻia e nā kumu he nui e like me ka holomua ʻenehana, ka ulu ʻana o ka mākeke a me ke kākoʻo kulekele, e hoʻomau ʻia ka hana ʻana o nā pahu kukui modula a e hoʻomau ka hoʻonui ʻia o ke kahua noi. I ka wā e hiki mai ana, loaʻa iā mākou ke kumu e manaʻoʻiʻo ai e pāʻani koʻikoʻi nā pahu kukui modula hōʻike LED ma nā kula hou aʻe a lawe mai i ka poʻe i kahi ʻike ʻike ʻoniʻoni.
