ʻO nā hōʻike LED COB (Chip on Board) kahi ʻenehana hōʻike kiʻekiʻe e hoʻokō i ka hoʻohui kiʻekiʻe a me ka hana ʻoi aku ka maikaʻi ma o ka hoʻopili pololei ʻana i nā chips LED ma nā papa kaapuni. Hoʻohālikelike ʻia i nā hōʻike LED SMD (Surface Mount Device) kuʻuna, hāʻawi ka ʻenehana COB i nā pono nui i ka hilinaʻi, ka like ʻana o ka mālamalama, a me ka ʻike ʻike. I nā makahiki i hala iho nei, ua hoʻohana nui ʻia i nā hōʻikeʻike pāʻoihana, nā hana keaka, a me ka -kiʻekiʻe kiʻekiʻe.
Mai kahi hiʻohiʻona ʻenehana, aia ka hiʻohiʻona nui o nā hōʻike COB LED i kā lākou ʻeke. Hoʻopaʻa pololei ʻia ka chip i ka substrate a pale ʻia me ka resin epoxy a i ʻole silicone, e hōʻemi nui ana i ka helu o nā hui solder a pēlā ka helu hāʻule. ʻAʻole wale kēia hoʻolālā e hoʻomaikaʻi i ka haʻalulu o ka huahana a me ka pale ʻana i ka hopena akā hoʻoponopono maikaʻi i ka pilikia "mālamalama make" maʻamau i nā pale LED kuʻuna. Eia kekahi, hāʻawi ka ʻenehana COB i kahi pitch pixel liʻiliʻi, e hiki ai i ka hoʻonā kiʻekiʻe a me nā kiʻi kikoʻī, akaka, kūpono loa ia no ka nānā ʻana -pili.
Ma ke ʻano o ka maikaʻi hōʻike, hāʻawi nā hōʻike COB LED i ka hoʻohālikelike maikaʻi loa a me ka hana hou kala. Ma muli o ka hana ʻana o ka ʻāpana pepa i ka hoʻoili ʻana i ka ʻike maka lua ma ke kumu kukui, ʻoi aku ka like o ka hāʻawi ʻana i ka māmā, e pale ana i ka hopena "grainy" maʻamau i nā pale kuʻuna.
Eia kekahi, ʻo kāna helu hoʻomaha kiʻekiʻe a me ka hoʻohana haʻahaʻa haʻahaʻa he koho maikaʻi loa ia no ka hōʻike kiʻi dynamic a me ka mālama ʻana i ka ikehu.
I kēia manawa, ua komo mālie nā hōʻike COB LED i nā mākeke kiʻekiʻe -e like me nā kikowaena kauoha, -kūʻai kūʻai kiʻekiʻe, a me nā kiʻi ʻoiaʻiʻo. Me ka hui ʻana o nā ʻenehana Mini/Micro LED, manaʻo ʻia nā hōʻike COB e hōʻemi hou i ka nui, hoʻomaikaʻi i ka ʻōlinolino, a hoʻonui i ka ikehu, e lilo i alakaʻi hoʻomohala nui i ka mākeke hōʻike pale nui. ʻOiai ʻoi aku ka kiʻekiʻe o kāna kumukūʻai hana ma mua o nā hoʻonā kuʻuna, e hoʻomau ka hoʻokūkū mākeke o COB LED i ka ulu ʻana o ka ʻenehana a piʻi i luna.
