AustarNā kukui alanui LEDhana ʻia e nā kukui alanui Led Manufacturers e loaʻa i nā pono ʻoi aku ma mua o nā huahana kuʻuna. ʻOi aku ka lōʻihi o ke ola o nā kukui alanui LED a ʻoi aku ka maikaʻi ma o ka hoʻololi ʻana i ka ikehu i mālamalama e ʻoki i ka wela e like me ka hiki.
ʻOiai naʻe, e hoʻomāhuahua mau ana nā kukui i ka wela, e hoʻopōʻino i nā kukui alanui Kina, me ka hoʻopau ʻana i ke ola, ka hoʻopōʻino ʻana i nā hopena kukui, a me ka hōʻemi ʻana i ka CRI. No laila, he mea nui ia o ka ʻoki ʻana i ka wela. ʻO nā pōmaikaʻi o ke kukui solid state (SSL).
ʻOiaʻiʻo, no nā kukui alanui LED, hopohopo nui ka mahana hana. ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka pōkole o ke ola. ʻAʻole hoʻolōʻihi ka mahana LED maʻamau i ke ola akā hāʻawi pū kekahi i ka mālamalama. Nui nā ala a me nā ala e hoʻomaikaʻi ai i ka hoʻokele thermal LED, me nā ʻano ʻelua o ka hoʻopili ʻana i nā mea resin a me nā mea hoʻonaninani thermally conductive.
Hoʻolālā ʻia ka mea hoʻoheheʻe thermally conductive ma ke ʻano he paʻa ma waena o ka ʻāpana a me ka wela wela e hoʻolalelale i ka wela e hoʻohaʻahaʻa i ka mahana hana. Eia kekahi, hoʻohana ʻia ka mea i hoʻōla ʻia ma ke ʻano he mea hoʻopili e uhi ana i ka RTV a i ʻole epoxy resin material, i koho ʻia e like me ka ikaika adhesive a me ka mahana hana.
ʻO kahi koho ʻē aʻe he mea hoʻonaninani thermally conductive encapsulating resin e hāʻawi ai i ka pale pono a me ka wela wela no ka hāmeʻa. Loaʻa nui nā mea resin encapsulated, me nā resins epoxy, resins polyurethane, a me nā resins silicone.
Hiki i nā resina polyurethane ke hoʻololi maikaʻi, ʻoi aku ka maikaʻi ma nā haʻahaʻa haʻahaʻa, ma ke ʻano he pono nui ma mua o nā resins epoxy. Eia kekahi, he hana like nā resins silicone, akā ma ke kumukūʻai kiʻekiʻe. E like me ka epoxy resin, he huahana ʻoi aku ka paʻakikī e hāʻawi i ka pale maikaʻi loa i nā wahi paʻakikī a paʻakikī. ʻO ka mea resin encapsulated e kōkua i ka hoʻolālā ʻana i nā kukui LED maʻamau e like me nā pono o ka mea kūʻai aku.
Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana uila, ka kikoʻī o nā noi LED, pono e hoʻomaikaʻi ʻia nā mea hoʻoluʻu e like me ia, e hāʻawi nui i ka hoʻomaikaʻi ʻana a me ka hoʻomohala ʻana i nā kukui alanui Kina.
