Nui nā hoʻohana o nā LED i ko mākou ola. He lōʻihi lākou a maikaʻi. I kēia manawa, ʻike mākou i kēia mau LED i nā ʻano āpau o ke ola. Hoʻokaʻawale hou mākou i nā LED i ʻelua ʻano. ʻO kēia nā COB a me SMD. ʻO COB ke kū nei no "Chip on Board". A ʻo SMD ke kū nei no "Surface Mounted Device."
Ma ka ʻatikala ma lalo nei, e kūkākūkā mākou iā lākou ʻelua. E hōʻike mākou i ka hana ʻana o kēia mau LED ʻelua. E kūkākūkā pū mākou i kā lākou mau hiʻohiʻona a me ka hana ʻana. E hoʻohālikelike mākou i kā lākou mau hana.
He aha ka COB LED?
ʻO ia kekahi o nā holomua hou i ke kahua o nā LED. He nui kona mau pono ma mua o nā ʻano LED ʻē aʻe.
Aia kekahi ʻano kikoʻī o nā pahu LED e pono ai e hana i nā kukui COB. Hoʻopili pū ʻia kēia mau ʻāpana. Eia kekahi, he kumu ia i hana ʻia me ka silika carbide. No laila, loaʻa iā mākou kahi puʻupuʻu LED me ka hoʻomālamalama maikaʻi loa, ʻo ia ke ʻano like. ʻO kēia hiʻohiʻona he mea kūpono ia no nā mea hana kiʻiʻoniʻoni. He kōkua nui nō hoʻi i nā mea paʻi kiʻi.
Hoʻohana nā pahu COB i ʻeiwa a ʻoi aku paha nā diodes. ʻAʻole hilinaʻi kona mau pilina a me ka pōʻai i ka helu o nā diodes. ʻOiaʻiʻo, loaʻa iā lākou hoʻokahi kaapuni a ʻelua mau pilina. Hiki iā ia ke hoʻoulu i nā kukui ʻoi aku ka maikaʻi inā piʻi nā pahu nui a hiki i 250 lumens. No laila, hāʻawi ia i kahi panel i kahi ʻano ma muli o ka hoʻolālā ʻana o kāna kaapuni. ʻAʻole pono kēia i nā kukui hoʻololi kala. No ka hoʻohana ʻana o kēia LED i hoʻokahi kaapuni.
Ka ʻike kumu o ka ʻenehana COB:
ʻOiaʻiʻo, ʻo nā kukui maoli ka ʻāpana mua o kahi ʻōnaehana kukui LED COB. Hōʻike ka "Chip On Board" (COB) i ka manaʻo o kēlā me kēia ʻāpana he nui nā pahu LED. Aia kēia mau ʻāpana ma ka ʻaoʻao i hana ʻia me ka seramika a i ʻole metala. ʻO nā LED he semiconductors e hoʻopuka ana i nā photons māmā.
Ua manaʻo ʻia ʻo ka nui o ka maikaʻi a me ka manawa holo pākaukau he mau mea kūʻē. Inā ʻoi aʻe ka ʻōlinolino, pōkole ka manawa holo o ka pākaukau. Ua hoʻololi ka ʻenehana COB i kēia ʻoiaʻiʻo. Hiki i nā COB LED ke hana i nā pae ʻālohilohi kiʻekiʻe me ka haʻahaʻa haʻahaʻa.
He aha ka SMD LED?
ʻO SMD e pili ana i nā mea i kau ʻia ma luna. ʻO SMD kahi ʻenehana no ka hana ʻana i nā kaapuni uila. Ma kēia ʻenehana, ua kau ʻia nā ʻāpana i nā papa kaapuni ma luna o lākou. He liʻiliʻi loa ka nui o nā LED SMD. ʻAʻohe ona pine a me ke alakaʻi. ʻOi aku ka maikaʻi o ka mālama ʻia e nā mīkini hui automated ma mua o ke kanaka. Ma muli o ka nele o ka casing epoxy hemispherical, hāʻawi pū kekahi SMD LED i kahi ākea ke nānā ʻana.
Hiki i nā LED SMD ke hana i ka mālamalama mālamalama me ka liʻiliʻi o ka wattage. He ʻano ia o ka LED e hoʻohui i ʻekolu kala mua i hoʻokahi encapsulation. Hoʻohana ia i ke kaʻina hana polarization no ka hui ʻana o ka papa kaapuni. Pono nā mea hana kiʻekiʻe no ka hoʻopau ʻana i kēia kaʻina hana. Kōkua ia i ka lanakila ʻana i nā pilikia he nui. Hoʻopili kēia i nā LED hana ʻole.
Ka ʻike kumu o ka ʻenehana SMD:
Hana pū ʻo SMD ma ka ʻenehana LED. Ua pani i ka ʻenehana kahiko. Ua hoʻohana ka mea kahiko i ke alakaʻi i ka wā hana. Ma ka ʻenehana SMD, hana mākou i ke kau ʻana ma nā mīkini liʻiliʻi liʻiliʻi. No laila, noho ia i kahi wahi liʻiliʻi. A hiki iā mākou ke hoʻohana maʻalahi i kēia ʻenehana i nā mea uila liʻiliʻi.
Hiki iā mākou ke hui pū me ka PCB me ka hoʻohana ʻana i kēia ʻenehana. Hoʻonui kēia ʻenehana i ka hilinaʻi, ka pono, a me ka hana.
ʻO nā ʻokoʻa nui ma waena o ka COB LED a me ka SMD LED:
I kēia manawa, e kūkākūkā mākou i kekahi mau hiʻohiʻona e hoʻokaʻawale i waena o kēia mau ʻano LED. ʻO kēia mau hiʻohiʻona e kōkua maikaʻi iā mākou e hoʻoholo i kahi mea maikaʻi e hoʻohana ai.
