ʻO nā mea e pili ana i ka maikaʻi a me ka palaho o ke kukui solar LED
ʻO ka mea mua, koho i ke ʻano o nā kukui solar LED.
He mea koʻikoʻi kēia, hiki ke ʻōlelo ʻia ke ʻano o nā kukui solar LED he mea nui loa. No ka hāʻawi ʻana i kekahi mau hiʻohiʻona, ua hōʻike ʻia ka ʻāpana kukui keʻokeʻo he 14mil e nā kukui kukui LED i hoʻopili ʻia me ka primer epoxy resin maʻamau a me ka hoʻopili kukui keʻokeʻo a me ke kāpili hoʻopili.
ʻO kahi kukui hoʻokahi i kahi kaiapuni 30-degree, hoʻokahi tausani mau hola ma hope, ʻO ka ʻikepili attenuation ʻo ka luminous mālama mālama o 70%; inā hoʻopili ʻia me ka D-type haʻahaʻa haʻahaʻa haʻahaʻa, ʻo ka attenuation māmā ʻo 45% i hoʻokahi tausani hola ma lalo o ka ʻelemakule like; inā hoʻopili ʻia me ka C-type low-failure glue, ʻo 12% ka pohō māmā o kēlā me kēia hola; inā hoʻopili ʻia ke kāpili haʻahaʻa haʻahaʻa ʻo Class B, ma lalo o ke ʻano o ka wā kahiko, ʻo 3% ka pohō māmā o nā tausani hola; inā ʻo ka papa A haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ma lalo o ke ʻano o ka wā kahiko, ʻo 6 %.
ʻO ka lua, ʻo ka mahana ambient hana o nā kukui solar LED.
Wahi a ka ʻikepili o kahi kukui kukui LED hoʻokahi i ka wā ʻelemakule inā hoʻokahi wale nō kukui kukui LED e hana, a aia ka mahana ambient ma 30 degere, a laila ʻaʻole e ʻoi aku ka mahana o ka bracket i ka wā e hana ai ke kukui keʻokeʻo LED hoʻokahi ma mua o 45 degere. I kēia manawa, kūpono ke ola o kēia LED.
Inā he 100 mau kukui kukui LED e hana ana i ka manawa like, a ʻo ka manawa ma waena o lākou he 11.4mm wale nō, a laila ʻaʻole i ʻoi aku ka mahana o ka bracket o nā kukui kukui LED a puni ka puʻu ma mua o 45 degere, akā ʻo kēlā mau kukui lā LED he a kiʻekiʻe wela a hiki i 65 degere. I kēia manawa, he ho'āʻo nā pahu kukui LED. A laila, ʻoi aku ka wikiwiki o ka pohō māmā o nā kukui lā LED e hōʻiliʻili ana ma waena, ʻoiai ʻo nā kukui lā o LED a puni ka puʻu e loaʻa i ka pohō māmā.
Eia naʻe, pono e ʻike nā mea a pau e makaʻu ana ʻo 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, ʻoi aku ka lōʻihi o ke ola LED. ʻO ka mahana hana maikaʻi o ka LED ma waena o 5 a me zero degere. Akā hiki ʻole kēia.
No laila, ma hope o ko mākou hoʻomaopopo ʻana i nā ʻāpana hana kūpono o nā kukui kukui LED, hoʻāʻo mākou i kā mākou mea maikaʻi loa e hoʻomaikaʻi i nā hana o ka conduction wela a me ka hoʻopau wela i ka wā e hoʻolālā ai i nā kukui. Eia nō naʻe, ʻoi aku ka haʻahaʻa o ka mahana, ʻoi aku ka lōʻihi o ke ola LED.
Ke kolu, Hoʻolālā ʻia nā ʻāpana uila hana o nā pahu kukui LED.
Wahi a nā hopena hoʻokolohua, ʻo ka haʻahaʻa o ka hoʻokele ʻana o ke kukui solar LED, ʻoi aku ka liʻiliʻi o ka wela i hoʻokuʻu ʻia, ʻoiaʻiʻo, ʻo ka haʻahaʻa o ka mālamalama. Wahi a ka noiʻi ʻana, ʻo ka hoʻolālā ʻana o ke kaapuni kukui lā o LED, ʻo ka hoʻokele o kēia manawa o LED he 5-10mA wale nō; ʻO nā huahana me ka nui o nā kukui kukui, e like me ka hiki ʻana aku ma mua o 500, a ʻoi aku paha, ʻo ka hoʻokele o kēia manawa he 10-15mA wale nō. ma luna o 15mA.
Hōʻike nā hopena hoʻokolohua ma lalo o ke kaʻa o kēia manawa o 14mA, a ʻaʻole impervious ka uhi i ka lewa, ʻo ka mahana o ka ea i loko a hiki i 71 degere, ʻo ka huahana haʻahaʻa haʻahaʻa ʻaʻohe māmā attenuation i nā hola 1000, a me 3% i 2000. hola. Hōʻike kēia i ka hoʻohana ʻana o ia mau kukui kukui LED haʻahaʻa i hiki i kona kiʻekiʻe i loko o ia ʻano, a ʻo ka pōʻino nui loa ia.
No ka mea, ʻaʻohe hana wela o ka papa ʻelemakule no ka ʻelemakule, ʻaʻole hiki ke alakaʻi ʻia ka wela i hana ʻia e ka LED i ka wā o ka hana i waho. Ua hōʻoia ʻia kēia ma ka hoʻokolohua. ʻO ka mahana o ka ea ma ka papa kahiko ua hiki i kahi kiʻekiʻe o 101 degere, a ʻo ka mahana wela o ka uhi ma ka papa ʻelemakule he 53 degere wale nō, ʻo ia ka ʻokoʻa o nā kekona degere. Hōʻike kēia ʻaʻole i loaʻa i ka uhi plastik i hoʻolālā ʻia ka hana o ka conduction wela a me ka dissipation wela.
Eia naʻe, ma keʻano laulā, manaʻo ʻia ka hoʻolālā kukui, ka hana o ka conduction wela a me ka dissipation wela. No laila, i ka hōʻuluʻulu ʻana, pono e hoʻokumu ʻia ka hoʻolālā ʻana o nā ʻāpana uila hana o ke kukui kukui LED ma ke kūlana maoli.
Inā maikaʻi loa ka hana wela a me ka hoʻoheheʻe wela o ke kukui, ʻaʻole ia he mea nui inā hoʻonui iki ka hoʻokele ʻana o ke kukui solar LED, no ka mea, hana nā kukui kukui LED Hiki ke lawe ʻia ka wela i waho koke, me ka ʻole. e hōʻino i ka LED, ʻo ia ka mālama maikaʻi loa no ka LED. ʻO ka mea ʻē aʻe, inā ʻoi aku ka liʻiliʻi o ka hoʻokele wela a me ka hoʻopau wela o ke kukui, ʻoi aku ka maikaʻi o ka hoʻolālā ʻana i ke kaapuni e liʻiliʻi a hoʻokuʻu i ka wela liʻiliʻi.
