Ke kūʻai aku nei i nā kukui, lohe pinepine i nā limahana kūʻai aku e ʻōlelo nei he mau kukui LED mākou, ka mālama ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu, i kēia manawa hiki ke lohe i nā wahi āpau e pili ana i nā huaʻōlelo alakaʻi, ma waho aʻe o kā mākou mau kukui alakaʻi i ka mālama kaiapuni a me ka mālama ʻana i ka ikehu, lohe pinepine mākou i ka poʻe e haʻi ana i nā kukui cob. , Ke manaʻoʻiʻo nei au he nui ka poʻe i ʻike ʻole i ka cob, a laila he aha ka cob?He aha ka ʻokoʻa me ke alakaʻi?
ʻO ke kamaʻilio mua e pili ana i ka LED, ʻo ke kukui alakaʻi he diode māmā e like me ke kumu kukui, ʻo kona ʻano kumu he electroluminescent semiconductor chip, he mea semiconductor solid-state, hiki iā ia ke hoʻololi pololei i ka uila i mālamalama.Hoʻopili ʻia kekahi ʻaoʻao o ka puʻupuʻu i kahi bracket, ʻo kekahi ʻaoʻao he electrode maikaʻi ʻole, a ʻo ka ʻaoʻao ʻē aʻe i pili i ka electrode maikaʻi o ka lako mana, i hoʻopili ʻia ka chip holoʻokoʻa e ka resin epoxy, ka mea e pale ai i ka uea kūloko. , a laila hoʻokomo ʻia ka pūpū, no laila maikaʻi ka hana seismic o ke kukui LED.ʻO ke kukui alakaʻi nui ka Angle, hiki ke hōʻea i 120-160 degere, ke hoʻohālikelike ʻia me ka pūʻolo plug-in mua kiʻekiʻe ka maikaʻi, ka pololei maikaʻi, ka haʻahaʻa haʻahaʻa haʻahaʻa, ke kaumaha māmā, ka leo liʻiliʻi a pēlā aku.
I nā lā mua, ʻike mākou i nā hale kūʻai barber, KTV, nā hale ʻaina, nā hale kiʻiʻoniʻoni a me nā kukui alakaʻi ʻē aʻe i haku ʻia me nā helu a i ʻole nā huaʻōlelo i hoʻohana nui ʻia i nā papa hoʻolaha, a ua hoʻohana ʻia nā kukui LED ma ke ʻano he mau hōʻailona a hōʻike i nā papa LED.Me ka puka ʻana o nā alakaʻi keʻokeʻo, hoʻohana ʻia lākou e like me ke kukui.
ʻIke ʻia ʻo LED ma ke ʻano he kumu kukui ʻehā a i ʻole kumu kukui ʻōmaʻomaʻo, me ka mālama ʻana i ka ikehu, ka mālama ʻana i ke kaiapuni, ke ola lōʻihi, ka liʻiliʻi liʻiliʻi, nā hiʻohiʻona palekana a hilinaʻi hoʻi, hoʻohana nui ʻia i nā ʻano hōʻailona, hōʻike, hoʻonani, backlight, kukui ākea a ʻano pō kaona a me nā kula ʻē aʻe.Wahi a ka hoʻohana ʻana i nā hana like ʻole, hiki ke hoʻokaʻawale ʻia i ka hōʻike ʻike, nā kukui kaʻa, nā kukui kaʻa, nā kukui LCD, nā kukui ākea ʻelima mau ʻāpana.
Ma ke kumumanaʻo, ʻo ke ola lawelawe o nā kukui LED (hoʻokahi kukui emitting diodes) he 10,000 mau hola.Eia naʻe, ma hope o ka hui ʻana i ke kukui, no ka mea, he ola nā mea uila ʻē aʻe, no laila ʻaʻole hiki i ke kukui LED ke hiki i 10,000 mau hola o ke ola lawelawe, ma ke ʻano nui, hiki ke hiki i 5,000 mau hola.
ʻO ke kumu kukui COB, ʻo ia ka mea i hoʻopili pololei ʻia ka chip ma ka substrate holoʻokoʻa, ʻo ia hoʻi, ua hoʻoili ʻia nā chip N a hoʻohui pū ʻia ma ka substrate no ka hoʻopili ʻana.Hoʻopau kēia ʻenehana i ka manaʻo o ke kākoʻo, ʻaʻohe plating, ʻaʻohe reflow, ʻaʻohe papa hana, no laila ua hoʻemi ʻia ke kaʻina hana ma kahi kokoke i 1/3, a mālama pū ʻia ke kumukūʻai e 1/3.Hoʻohana nui ʻia ia e hoʻoponopono i ka pilikia o ka hana haʻahaʻa haʻahaʻa i nā kukui LED mana kiʻekiʻe, hiki ke hoʻopuehu i ka hoʻoheheʻe ʻana o ka wela o ka chip, hoʻomaikaʻi i ka māmā māmā, a hoʻomaikaʻi i ka hopena o nā kukui LED.Loaʻa i ka COB ke kiʻekiʻe o ka luminous flux density, ka liʻiliʻi a me ke kukui palupalu, a hoʻokuʻu i ka hāʻawi like ʻana o ka mālamalama.Ma nā ʻōlelo kaulana, ʻoi aku ka holomua ma mua o nā kukui alakaʻi, ʻoi aku ka nui o nā kukui pale maka.
ʻO ka ʻokoʻa ma waena o ke kukui Cob a me ke kukui alakaʻi ʻo ia ke kukui alakaʻi e hiki ke mālama i ka pale o ke kaiapuni, ʻaʻohe stroboscopic, ʻaʻohe radiation ultraviolet, a ʻo ka hemahema ka pōʻino o ke kukui uliuli.ʻO ke kukui Cob ka waihoʻoluʻu kiʻekiʻe, ka waihoʻoluʻu māmā kokoke i ka waihoʻoluʻu maoli, ʻaʻohe stroboscopic, ʻaʻohe ʻālohilohi, ʻaʻohe electromagnetic radiation, ʻaʻohe ultraviolet radiation, hiki ke pale aku i nā maka a me ka ʻili.ʻO kēia mau mea ʻelua he LED maoli, akā ʻokoʻa ke ʻano o ka hoʻopili ʻana, ʻoi aku ka maikaʻi o ke kaʻina hana cob packaging a me ka māmā māmā, ʻo ia ke ʻano hoʻomohala e hiki mai ana.
