E ʻike i ka ʻenehana COB: ʻAi ʻole a me ka maikaʻi

I kēia lā e holomua wikiwiki nei ka ʻenehana, ua ulu nui nā ʻōnaehana hōʻike LED. Ua hoʻololi ka ʻenehana LED i ka ʻoihana kukui, e hāʻawi ana i nā koho ikaika a lōʻihi i nā mea kūʻai aku a me nā ʻoihana like. Ma waena o nā hoʻonohonoho LED like ʻole, ua puka mai ʻo COB (Chip on Board) ma ke ʻano he koho maikaʻi loa ma muli o kāna mau ʻano loea. Ma kēia ʻatikala, e ʻimi mākou i nā kumu e paʻa ai ka COB i ka pono ma mua o ka ʻenehana SMD (Surface Mount Device) i hoʻohana nui ʻia. Mai kāna mau haʻahaʻa haʻahaʻa haʻahaʻa a hiki i ka hoʻomaikaʻi ʻana i ka pale ʻana i nā kumu kūlohelohe, ʻoi aku ka maikaʻi o COB i kāna mau mea hoʻokūkū.

I ka hiki ʻana i ka ʻenehana hōʻike LED, ʻelua mau mea hoʻokūkū koʻikoʻi i ka mākeke: SMD a me COB. ʻOiai ʻo Surface Mount Device ka lōʻihi o ke koho ʻana no nā hoʻonā kukui LED, ua puka mai ʻo COB ma ke ʻano he koho weliweli.

ʻAʻole like me SMD, nona nā diodes LED i hoʻopaʻa ʻia ma ka papa kaapuni, hoʻokomo ʻo COB i nā pahu kukui LED he nui i loko o hoʻokahi module. ʻAʻole kēia hoʻonohonoho kūʻokoʻa e hoʻonui i ka ʻōlinolino a me ka ikaika o ke kukui akā e hōʻemi pū i ka attenuation o ke kukui ma nā mamao lōʻihi. Loaʻa ka hoʻolālā ʻoki ʻoki a COB i kahi puka māmā māmā me ka like ʻole a me ke kala kiʻekiʻe.

II. Haʻahaʻa wela me ka liʻiliʻi o ka wela

ʻO kekahi o nā pōmaikaʻi nui o COB ma luna o SMD ʻo ia kona mana hoʻokele wela. Hāʻawi ka ʻenehana COB i ka pale wela haʻahaʻa ma muli o kāna hoʻolālā paʻa. Hoʻoholo ka pale ʻana i ka wela i ka hemo ʻana o ka wela mai ka module LED, e ʻoi aku ka maikaʻi o ka COB i ka hōʻemi ʻana i ka wela. ʻO kēia ka hopena i ka hoʻomaikaʻi ʻana i ka lōʻihi a me ka hōʻemi ʻana i nā pono mālama akā hoʻonui pū i ka palekana e like meCOB modulesua emi iki ka wela.

III. Palekana maikaʻi loa i nā kumu kaiapuni

Hōʻike COBhāʻawi i ka palekana maikaʻi loa i nā ʻano mea kaiapuni, e hōʻoia ana i ka paʻa a me ka hilinaʻi i nā kūlana like ʻole. Hoʻōla ʻia me ka resin epoxy e hoʻomaikaʻi i ka hana pale. Hāʻawi ia i ke kūpaʻa kiʻekiʻe i ka makū, ka lepo, static, oxidation, a me ke kukui uliuli. ʻO kēia palekana i hoʻonui ʻia e hiki ai i nā hoʻonā kukui COB ke holomua ma nā wahi paʻakikī e like me nā hoʻonohonoho waho a i ʻole nā ​​​​wahi me ka haʻahaʻa kiʻekiʻe. Hoʻohui hou, ʻo ke kūpaʻa kiʻekiʻe o COB i ka oxidation e hōʻoia i ka mālama ʻana o nā LED i ko lākou ʻōlinolino a me ka pololei kala i nā manawa lōʻihi, ʻaʻole like me kā lākou mau hoa SMD.

IV. ʻOi aku ka maikaʻi o ka ʻeleʻele a me ka ʻoi.

ʻAʻole hoʻomaikaʻi wale ka hoʻolālā ʻenehana COB i kāna hoʻokele wela a me ka hiki ke pale aku akā kōkua pū kekahi i kona ʻano kukui. Ma muli o nā ʻāpana LED e pili kokoke ana, hoʻopuka ʻo COB i kahi kukui ʻoi aku ka ʻoi aʻe a me ka ikaika, e hopena i nā aka ʻeleʻele a me nā kikoʻī kikoʻī. He mea kūpono kēia i ka COB no nā noi kahi e koʻikoʻi ai ka pololei a me ka ʻokoʻa kiʻekiʻe, e like me nā hale hōʻikeʻike, nā hale kūʻai kūʻai, a me nā hale kiʻi. ʻO ke kukui ʻoi aku ka maikaʻi i hāʻawi ʻia e ka ʻenehana COB e hoʻonui i ka hoʻopiʻi ʻike a me ka mālamalama o nā wahi i hoʻomālamalama ʻia.

Ke hoʻomau nei ka ulu ʻana o ka ʻoihana LED Display,ʻenehana COBua puka mai ma ke ʻano he koho hou a ʻoi aku ka maikaʻi no nā hopena hōʻike LED. ʻO kāna mau hiʻohiʻona ʻenehana, e like me ka hoʻokuʻu ʻana i nā kukui like ʻole, nā haʻahaʻa haʻahaʻa haʻahaʻa, hoʻomaikaʻi i ka pale ʻana i nā mea kūlohelohe, a me nā kukui ʻoi aku ka maikaʻi, e hana ia i kahi koho unbeatable. ʻAʻole hāʻawi wale ʻo COB i ka hoʻomaikaʻi ʻana i ka hana a me ka lōʻihi akā hāʻawi pū kekahi i ka maikaʻi ʻike maikaʻi, pono ia no nā noi like ʻole.

Me kona hoʻonui kaulana a me ka holomua i nā kaʻina hana,ʻenehana COBhiki ke loaʻa i nā mea kūʻai a me nā ʻoihana a puni ka honua. Puhi ana Hōʻike COBhoʻohiki nā solutions e hāʻawi i nā koho kukui ʻoi aku ka mālamalama, ʻoi aku ka maikaʻi, a ʻoi aku ka lōʻihi o ka hoʻololi ʻana i ke ala a mākou e hoʻomālamalama ai i ko mākou puni.
