He aha ka manaʻo o ka smd light strip?

Me ka kaulana o ka manaʻo hoʻolālā "no main light lighting", LED linear light strip e lilo i mea kaulana loa i ka hoʻonaninani hale a me nā papahana hana hana hale holoʻokoʻa. ʻEkolu mau mea hoʻoheheʻe kukui māmā LED maʻamau ma ka mākeke, ʻo ia hoʻi nā SMD LED light strips, COB LED light strips a me nā ʻāpana kukui LED CSP hou loa. ʻOiai ua loaʻa i kēlā me kēia huahana kona mau pono a me nā ʻokoʻa, e hoʻāʻo ka mea hoʻoponopono e hoʻohana i hoʻokahi ʻatikala e hoʻomaopopo iā ʻoe i nā ʻokoʻa ma waena o nā ʻekolu, i hiki iā ʻoe ke hana i ke koho kūpono.

ʻO nā ʻāpana kukui SMD, ka inoa piha o Surface Mounted Devices (Surface Mounted Devices) light strips, e nānā i ka pahu kukui LED e kau pololei ʻia ma ka substrate o ke kaula kukui, a laila hoʻopili ʻia e hana i nā lālani o nā pahu kukui liʻiliʻi. ʻO kēia ʻano ʻāpana kukui he ʻano maʻamau o ke kukui kukui LED, ka mea maʻamau i nā ʻano o ka maʻalahi, ka lahilahi, ka mālama mana, a me ke ola lōʻihi.

ʻO SMD ka pōkole o "Surface Mount Device", ʻo ia ke ʻano maʻamau o ka hāmeʻa LED i kēia manawa ma ka mākeke. Hoʻopili ʻia ka puʻupuʻu LED i loko o ka pūpū bracket LED me ka phosphor glue a laila kau ʻia ma kahi papa kaapuni paʻi maʻalahi (PCB). Ua kaulana loa nā ʻāpana LED SMD ma muli o ko lākou maʻalahi. , Hiki mai nā mea SMD LED i nā nui likeʻole: 3528, 5050, 2835, 3014, 2216, 2110; Ua kapa ʻia lākou e like me ko lākou nui kokoke, no ka laʻana, ʻo ka nui o 3528 ʻo 3.5 x 2.8mm, 5050 ʻo 5.0 x 5.0mm, a ʻo 2835 ʻo 2.8 x 3.5mm, 3014 ʻo 3.0 x 1.4mm.

Ma muli o ka hoʻohana ʻana o nā ʻāpana kukui SMD LED maʻamau i nā ʻāpana SMD LED ʻokoʻa, ʻoi aku ka nui o ka mamao/ʻokoʻa ma waena o ʻelua mau mea LED pili. Ke hoʻā ʻia ka ʻāʻī kukui, hiki iā ʻoe ke ʻike i nā kiko kukui hoʻokahi. Wahi a kekahi poʻe no nā wahi wela a i ʻole nā ​​mea koʻikoʻi. No laila, inā ʻaʻole ʻoe makemake e ʻike i nā wahi wela a i ʻole nā ​​wahi ʻālohilohi, pono ʻoe e hoʻohana i kekahi mea uhi (e like me ka uhi plastik) e kau ai ma luna o ke kāʻei SMD LED, a pono ʻoe e waiho i kahi kiʻekiʻe no ka hui ʻana o ka māmā e ʻoki. nā ʻōlinolino Ka hopena ʻulaʻula, no laila ʻano mānoanoa nā ʻaoʻao alumini i hoʻohana mau ʻia.

ʻO ka pahu kukui COB, ʻo ka inoa piha ʻo Chips On Board LED light strip, he ʻano ʻāpana kukui LED me ka chip ma luna o ka pahu (Chips On Board). Hoʻohālikelike ʻia me nā ʻāpana kukui SMD, ua hoʻopili pololei nā ʻāpana kukui COB i nā pahu kukui LED he nui ma ka papa kaapuni e hana i kahi ʻāpana kukui nui aʻe, ka mea maʻamau i hoʻohana ʻia i nā hiʻohiʻona noi e koi ana i nā kukui like ʻole.

Mahalo i ka uhi ʻana o ka phosphor glue mau, hiki i nā ʻāpana LED COB ke hoʻopuka i nā kukui like ʻole me ka ʻike ʻole ʻia o kahi kukui hoʻokahi, no laila hiki iā lākou ke hoʻopuka i nā kukui me ka kūlike maikaʻi me ka ʻole o ka pono o nā uhi plastik hou. , inā pono ʻoe e hoʻohana i nā pahu alumini, hiki iā ʻoe ke koho i nā kiʻi alumini palahalaha lahilahi.

ʻO CSP kekahi o nā ʻenehana hou loa i ka ʻoihana LED. Ma ka ʻoihana LED, ʻike ʻo CSP i ka ʻano ʻāpana liʻiliʻi a maʻalahi loa me ka ʻole o kahi substrate a i ʻole uea gula. ʻOkoʻa mai ka ʻenehana SMD light strip board, hoʻohana ʻo CSP i nā papa kaapuni maʻalahi FPC roll-to-roll.

ʻO FPC kahi ʻano uwea hou i hana ʻia me ke kiʻiʻoniʻoni insulating a me ka uea keleawe pālahalaha loa, i kaomi pū ʻia ma o kahi laina hana laminating automated. Loaʻa iā ia nā pōmaikaʻi o ka palupalu, manuahi a me ka pelu ʻana, ka mānoanoa lahilahi, ka liʻiliʻi liʻiliʻi, ka pololei kiʻekiʻe, a me ka conductivity ikaika.

Ke hoʻohālikelike ʻia me ka puʻupuʻu SMD kuʻuna, ʻoi aku ka maʻalahi o ka paʻi CSP, ʻoi aku ka liʻiliʻi o nā mea hoʻohana, nā kumu kūʻai haʻahaʻa, a ʻoi aku ka nui o ka huina kukui a me ke kuhikuhi ʻana ma mua o nā ʻano ʻāpana ʻē aʻe. Ma muli o ke ʻano o kāna kaʻina hana hoʻopili, hiki ke ʻoi aku ka liʻiliʻi o nā ʻāpana kukui CSP, ʻoi aku ka māmā a me ka māmā, a ʻoi aku ka liʻiliʻi o nā piko koʻikoʻi. I ka manawa like, nui kona kihi kukui, a hiki i 160 °, a maʻemaʻe a palupalu ke kala māmā, ʻaʻohe ʻaoʻao melemele. ʻO ka hiʻohiʻona nui o nā ʻāpana kukui CSP ʻaʻole hiki iā lākou ke ʻike i ka mālamalama a palupalu a palupalu.
