Pehea e pili ana i ke kumu kukui COB mehana ʻelua

WeiohaJ kaiManchester., lima. ua hoʻokuʻu i ka 3030 patch lamp bead series, i kēia manawa i hoʻohana nui ʻia i nā kukui ʻoihana, nā kukui kalepa, nā kukui ʻāina a me nā māla ʻē aʻe. ʻO kēia pūʻulu huahana he kumu kukui SMD patch i hana ʻia me ka mea PCT. ʻO ke kumu kukui COB ka ʻenehana kumu kukui hoʻohui i hoʻohui ʻia i hoʻopili pololei ʻia i ka substrate metala aniani kiʻekiʻe ma ka reflux kiʻekiʻe o nā chip LED. Hoʻihoʻi i ka welding a me ka non-patch kaʻina, no laila ua hoʻemi ʻia ke kaʻina hana ma kahi kokoke i hoʻokahi hapakolu, a mālama ʻia ke kumukūʻai e ka hapakolu. Ma keʻano laulā, ʻoi aku ka holomua a ʻoi aku ka nānā ʻana ma mua o nā kukui LED. Mai ka nānā ʻana i ka helu o nā chips a me ka hoʻohui pū ʻana o ka chip, ua ʻike ʻia ʻo ka hoʻopili ʻana i ka multi-chip keʻokeʻo LED knot e piʻi aʻe me ka piʻi ʻana o ka nui o nā chips integrated. Ua emi iho ka pono o ka naʻau me ka piʻi ʻana o ka nui o nā chips i hoʻohui ʻia. No laila ʻo ka nui a me ka hoʻohui pū ʻana he mea koʻikoʻi hoʻi i ka hoʻohana ʻana i ka ʻenehana hoʻopili paʻa. Hoʻohālikelike ʻia ke kumu kukui COB ʻelua-color me nā mea maikaʻi o ka liʻiliʻi, kiʻekiʻe o kēia manawa, kiʻekiʻe ka mana, kiʻekiʻe-māmā, haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe kūlike, kumukūʻai-effectiveness a me nā kumu kūʻai-effectiveness i hoʻohālikelike ʻia i nā huahana patch mainstream ma ka mākeke. He aha ke kumu kukui LED? Nīnau pinepine nā hoaaloha i kamaʻāina ʻole i kēia nīnau i nā hoaaloha i kamaʻāina i ka projector. Ke hoʻohālikelike ʻia me nā kumu kukui maʻamau, ʻoi aku ka liʻiliʻi o ka nui o nā kumu kukui LED. No laila, nui nā mea akamai liʻiliʻi i ka mākeke i kēia manawa. No ka mea he kino ʻālohilohi ʻo LED, ʻoi aku ka kiʻekiʻe o kona māmā e like me 120LM/W, ʻoi aku ka kiʻekiʻe ma mua o ka 70LM/W a me 100LM/W o ka pahu kukui T5, e hoʻonui ai i ka hopena māmā o ka pahu kukui LED. . A ʻo kekahi ʻano hoʻohuli inverted LED, no ka mea hiki ke hoʻohui ʻia a hana nui ʻia, he mākaukau maʻalahi a me ka hana maikaʻi loa, loaʻa iki ka manaʻo ākea o ka ʻoihana kukui. Hoʻohana pololei ka ʻōnaehana inverted i ka chip PN me ka pou maikaʻi a me ka maikaʻi ʻole co-crystal paʻa ma ka substrate, ʻaʻole hoʻohana i ke kelepona gula, a pale ʻia ka nui. I ka wā o ka hoʻohana ʻana i nā LED kiʻekiʻe, hiki ʻole ke ʻano o ka hopena o kēia manawa. I kēia hihia, inā ʻaʻole maikaʻi ke kūpaʻa o ke kūpaʻa nui o kēia manawa o nā kukui, maʻalahi ka hoʻemi ʻana i ke ola lawelawe o ke kukui. ʻO ke kumu kukui COB mahana ʻelua no ka mea ua hoʻohana ʻia ke kumu kukui LED. No laila, hiki ke loaʻa ka pōmaikaʻi nui. Pono ke kumu kukui ʻōpuʻu kukui maʻamau i kahi ākea nui e hoʻopau i ka wela. Kapa 'ia 'o Everbright diodes he mau LED i ho'okomo 'ia. ʻO ka diode ʻālohilohi wale nō kahi puʻupuʻu uila liʻiliʻi. Akā ʻaʻole like me nā ʻōpuʻu incandescent maʻamau, ʻaʻohe filament o ka light emitting diode, a ʻaʻole e wela loa. ʻO ka hopena māmā liʻiliʻi ʻo ia ka māmā-manawa kukui o nā kumu kukui LED. Ka helu, ka hoʻouna māmā ʻana, ka hoʻolālā bracket (reflector cup) no ka noʻonoʻo ʻana a me nā kūlana ʻē aʻe, ʻaʻole pili i ka wela o ka puʻupuʻu chip. E ana wale ia i ka manaʻo hoʻohālikelike, a ʻaʻole hiki i ka hopena māmā transient ke hōʻike i ke kūlana hana maoli. Ma ke ʻano he ʻoihana e puka mai ana i koʻu ʻāina, semiconductor light. Eia nō naʻe, ma ke kahua o nā kumu kukui LED kūikawā, ma muli o ka paepae ʻenehana kiʻekiʻe, ua hoʻokele ʻia ka mākeke e nā hui haole. ʻO ke kumu kukui COB ʻelua ʻulaʻula wale nō e ka neʻe electron i ka mea semiconductor e ʻā. No ka pau ʻana o nā diodes māmā me ka ʻole o nā filament, ʻoi aku ka lōʻihi o ke ola.
