He aha nā mea e pili ana i ka pōʻino o ke kukui LED ʻole AC?

1. AC-free LED pono'ī pilikia maikaʻi: 1. ʻAʻole maikaʻi ka chip LED i hoʻohana ʻia, a ʻoi aku ka wikiwiki o ka attenuation kukui. 2. Aia nā hemahema i ke kaʻina hana. ʻAʻole hiki ke alakaʻi maikaʻi ʻia ka hoʻoheheʻe ʻana o ka puʻupuʻu LED mai ka wāwae PIN, ka hopena i ka wela o ka puʻupuʻu LED e hoʻonui ai i ka attenuation o ka chip. 2. LauHo: 1. ʻO LED ka holo kahawai mau. Hoʻohana kekahi mau LED i nā mea hoʻokele uila e hana i ka attenuation LED. 2. ʻOi aku ka nui o ka mea hoʻokele i kēia manawa ma mua o ke kūlana hoʻokele i helu ʻia. ʻOiaʻiʻo, nui nā kumu no ka pohō māmā o nā huahana LED AC-free. ʻO ke kī ka pilikia o ka wela. ʻOiai ʻaʻole nānā nui nā mea hana i ka pilikia o ka dissipation wela, e hoʻohana ʻia kēia mau huahana LED lua no ka manawa lōʻihi. Pono e kiʻekiʻe nā huahana LED e nānā pono ana i ka wela. ʻO ke kūpaʻa wela o ka chip LED ponoʻī, ka hopena o ke kala kala, ka hopena wela o ka substrate, a me ke ʻano o ka colloid a me ka laina gula e pili pū ana me ka palaho māmā. ʻEkolu mau mea e pili ana i ka palaho kukui maikaʻi o nā kukui LED, ʻo ka mea mua, he aha ke ʻano o nā kukui keʻokeʻo LED e koho ai. Mina> holoh. ʻO ka maikaʻi o AC-free LED hiki ke ʻōlelo ʻia he kumu nui loa. No ka laʻana, ua hōʻike ʻia ka mea like me ka chip o ka chip 14mil, a ʻo nā kukui keʻokeʻo LED i hoʻopili ʻia e ka ʻōpala lalo a me ke keʻokeʻo keʻokeʻo a me ke kāpili kāpili i hana ʻia i ka resin epoxy maʻamau e hoʻomālamalama ʻia i kahi kaiapuni 30-degree. Ma hope o nā kaukani hola, ʻo ka ʻikepili i hoʻopaʻa ʻia ʻo 70% o ka pohō māmā; inā hoʻopili ʻia ka D type D haʻahaʻa haʻahaʻa haʻahaʻa, i loko o ke ʻano o ka wā kahiko, ʻo ka 1,000-hola pōpopo māmā he 45%; , 1,000-hola popopo malamalama he 12%; inā hoʻopili ʻia ka ʻāpana B i loko o ka liʻiliʻi haʻahaʻa haʻahaʻa, i ka wā kahiko, mau tausani hola o ka pohō māmā o -3%; ina Papa A haʻahaʻa palaho ke kāpili, i loko o ka ia elemakule kaiapuni, tausani hola o ka malamalama, tausani hola o ka malamalama Dechat mea -6%. ʻO ka lua, ka mahana hana o nā kukui kukui LED. Wahi a ka ʻikepili i ka wā e ʻelemakule ai ke kukui keʻokeʻo LED hoʻokahi, inā hoʻokahi wale nō hana kukui o ke kukui keʻokeʻo LED, i ka manawa like, ʻo ka mahana o ke kaiapuni i loaʻa he 30 degere, a laila ka mahana bracket o kahi LED AC-free LED. ʻAʻole hoʻokele i ka hana LED. Wehai Yok45 kena. I kēia manawa, kūpono ke ola o kēia LED. Inā he 100 mau kukui keʻokeʻo LED ma ka hana hoʻokahi i ka manawa like, ʻo ka manawa ma waena o lākou he 11.4mm wale nō, a laila ʻaʻole ʻoi aku ka mahana o ka mahana bracket o nā kukui keʻokeʻo LED a puni ka puʻu kukui ma mua o 45 degere, akā ʻo ka waena. o ka puʻu kukui i waenakonu o ka puʻu kukui. Hiki i kēlā mau kukui keʻokeʻo LED ke piʻi i 65 degere kiʻekiʻe. I kēia manawa, he ho'āʻo ke kukui kukui LED. A laila, ʻo kēlā mau kukui keʻokeʻo LED i hōʻuluʻulu ʻia i ka theoret e ʻoi aku ka wikiwiki o ke kukui, a ʻoi aku ka lohi o ke kukui keʻokeʻo LED a puni nā kukui. Eia nō naʻe, pono e ʻike nā mea a pau e makaʻu ka LED i ka wela. ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka pōkole o ke ola LED, ʻoi aku ka haʻahaʻa o ka mahana, a ʻoi aku ka lōʻihi o ke ola LED. ʻO ka mahana hana o ka LED maikaʻi loa ma waena o 5 a i ʻole nā ​​degere ʻino. Akā hiki ʻole kēia. No laila, ma hope o ko mākou hoʻomaopopo ʻana i nā ʻāpana hana kūpono o nā kukui kukui LED, pono mākou e hoʻoikaika i ka hana o ka conduction wela a me ka hoʻopau ʻana i ka wela i ka wā e hoʻolālā ai i nā kukui e like me ka hiki ke hoʻolālā i nā kukui e like me ka hiki. Eia nō naʻe, ʻoi aku ka haʻahaʻa o ka mahana, ʻoi aku ka lōʻihi o ke ola LED. ʻO ke kolu, AC-free LED hana uila uila hoʻolālā. ʻO ke kumu kukui ʻaoʻao LED i hoʻoheheʻe ʻia ʻo ia hoʻi ʻo ke ʻano hoʻoheheʻe ʻia ʻana o ke kukui LED ʻāwīwī ʻana i ka wai hoʻoheheʻe kelu module Hongyan cab triple-in-cab. ʻEkolu -hoʻokahi mea hana kaumaha E like me nā hopena hoʻokolohua, ʻoi aku ka liʻiliʻi o ke kukui keʻokeʻo LED, ʻoi aku ka liʻiliʻi o ka wela, ka liʻiliʻi, ka ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o ka mālamalama. Wahi a ka noiʻi ʻana, ʻo ka hoʻolālā ʻana o ke kaapuni kukui lā o LED, ʻo ka mea hoʻokele o kēia manawa o LED he 5-10mA wale nō; ʻO ka nui o nā kukui i hoʻohana ʻia i nā kukui, e like me ka ʻoi aku ma mua o 500 a ʻoi aʻe a ʻoi aku ka nui o nā kukui uila uila uila e alakaʻi nei i nā au he 15-18mA wale nō, a he liʻiliʻi ka poʻe i hoʻolālā i kēia manawa i ʻoi aku ma mua o 20mA. Ua hōʻike ʻia nā hopena hoʻokolohua ma lalo o ka mea hoʻokele o kēia manawa o 14mA, a ʻaʻole i hoʻoheheʻe ʻia ke poʻi, ʻo ka mahana o ka ea i hiki i ka 71 degere, haʻahaʻa haʻahaʻa huahana, 1,000 -hola pohō māmā, 2000 mau hola o ka pohō māmā o 3% a 3% , 3% palaho he 3%. Hōʻike kēia ua hiki i kēia kukui keʻokeʻo LED haʻahaʻa i kona palena maikaʻi loa i loko o ia ʻano. No ka nui o ia mea, he poino ia. No ka mea, ʻaʻohe hana hoʻoheheʻe wela o ka papa ʻelemakule no ka ʻelemakule, ʻaʻole hiki i ka wela i hana ʻia e AC-free LED ʻaʻole hiki ke hoʻouna i waho. Aloha poʻohonohonohahlingg. ʻO ka ea wela o ka panel kahiko i hiki i kahi kiʻekiʻe o 101 degere. ʻO ka mahana wela o ka poʻi ma ka panel kahiko he 53 degere wale nō, ʻo ia hoʻi nā kekona degere. Hōʻike kēia ʻaʻole i loaʻa i ka poʻi plastik i hoʻolālā ʻia ka hana o ka lawe ʻana i ka wela a me ka wela. Akā i ka hoʻolālā kukui maʻamau, e noʻonoʻo ana i ka hana o ka hoʻokele wela a me ka wela. No laila, i ka hōʻuluʻulu ʻana, pono e hoʻokumu ʻia ka hoʻolālā ʻana o nā ʻāpana uila hana o nā kukui kukui LED ma ke kūlana maoli. Inā maikaʻi loa ka hana hoʻoheheʻe wela o ke kukui, ʻoi aku ka maikaʻi o ka hoʻonui ʻana i ke ʻano o nā kukui keʻokeʻo LED, no ka mea, hana nā kukui kukui LED. Hiki ke hoʻokuʻu aku i ka wela i waho, aʻaʻohe meaʻino i ka LED,ʻo ia ka mālamaʻana i ka LED. ʻO ka mea ʻē aʻe, inā paheʻe ka hana hoʻoheheʻe wela o ke kukui, ua hoʻolālā ʻia ke kaapuni i mea liʻiliʻi, no laila e hoʻemi ʻia ka wela mai ia mea.
