He Whakamārama Taipitopito mō ngā Aratau Hononga e 4 mō ngā Atekōkiri LED
I tēnei wā, ko te nuinga o ngā hua rama LED e whakamahi ana i te aratau taraiwa au pumau hei whakataurite i ngā āhuatanga whakahaere o ngā rama LED. Hei whakatutuki i ngā hiahia o ngā hoahoa ara iahiko rerekē, ko ngā momo hononga noa o ngā rama LED e wehea ana kia whā ngā momo: raupapa, whakarara, huinga raupapa-whakarara, me te rarangi. He āhuatanga hanganga ara iahiko, he painga tono, me ngā herenga anō hoki tō ia aratau, ka whakamāramahia i raro nei.
1. Aratau Hononga Raupapa;
Ko te hanganga matua o te hononga raupapa ko te hono i ngā rama LED mai i te pito ki te pito i roto i te raupapatanga kia hanga he porowhita kati. Mō ngā āhuatanga whakahaere, ko ngā painga matua o tēnei aratau hononga ko te hanganga ara iahiko māmā, te mahi hononga watea, me te rere o te iahiko i roto i ngā rama LED katoa he tino ōrite i te wā e mahi ana. Nā te mea he momo iahiko noa ngā rama LED, mā te ōrite o te iahiko ka taea te whakarite tika i te kaha kanapa ōrite o ia rama LED, me te karo i ngā rerekētanga kanapa.
Me mōhio ko te momo pūtake hiko taraiwa ka pā ki te whānuitanga pānga hapa o te ara iahiko raupapa: ki te whakamahia he pūtake hiko taraiwa ngaohiko pumau, ina whakapotohia tetahi o ngā LED, ka piki tere te ia o te ara iahiko katoa. Ina nui ake te iahiko i te uara whārite kua whakatauria o te LED, ka pakaru tuatahi ngā taputapu e karapoti ana i te LED whakapotohia, kātahi ka pakaru ngā LED katoa i muri mai; ki te whakamahia he pūtake hiko taraiwa iahiko pumau, ahakoa whakapotohia tetahi o ngā LED, ka noho tonu te ia o te ara iahiko, ā, e kore e pā ki ētahi atu LED. Heoi, ahakoa te aratau taraiwa i whakamahia, mena ka puta he hapa ara iahiko tuwhera LED, e kore e taea te tahu i te aho rama katoa.
2. Aratau Hononga Whakarara
Ko te āhuatanga hanganga o te hononga whakarara ko te hononga o ngā pito o ngā LED katoa, arā, ka honoa ngā anode o ngā LED katoa, ā, ka honoa ngā cathode. I tēnei aratau hononga, he ōrite te ngaohiko puta noa i ia LED, engari kāore e ōrite te iahiko e rere ana i roto i ia LED—ahakoa ka tīpakohia ngā LED o te tauira me te puranga whakatakotoranga kotahi, ka kore e ōrite te tohatoha iahiko nā te mea he iti noa ngā rerekētanga o ngā tukanga whakaputa me te hanga. Ka pā tika te tohatoha iahiko kore ōrite ki te roa o te mahi a ngā LED. Ka tere ake te tawhito o ngā LED he nui rawa te iahiko, ka tino poto te roa o te mahi, ā, ka ngawari te tahuna i muri i te whakamahinga roa.
Mō te uaua o te ara iahiko, he rite te aratau hononga whakarara ki te aratau hononga raupapa, he hanganga ara iahiko māmā noa iho ēnei e rua, engari kāore i te tino pono. Ina koa i ngā āhuatanga he nui ngā rama LED, ka nui ake te tūponotanga o te rahunga.
Me mōhio he iti ngā whakaritenga hiko o te aratau hononga whakarara, ā, he pai ake mō ngā āhuatanga taraiwa hiko iti, engari e rua ngā raruraru matua: tuatahi, ko te rerekētanga o te hekenga hiko whakamua o ngā LED rerekē ka arahi ki te kanapa koretake, ka pā ki te pānga kanapa; tuarua, he motuhake te pānga o te hapa—ki te poto te ara iahiko o tētahi LED, ka puta he ara iahiko poto o te ara iahiko katoa, ā, kāore e taea e ngā LED katoa te mahi noa; ki te tuwhera te ara iahiko o tētahi LED, i te wā e whakamahia ana te puku au pumau, ka taupatupatu te iahiko i tohaina ki tēnei LED ki runga i ngā LED e toe ana, ka arahi ki te kino o te au nui o ngā LED e toe ana, i te wā e whakamahia ana te puku au pumau, kāore e pā ki te mahi noa o te ara iahiko LED katoa.
Ko te aratau whakakotahi raupapa-whakarara he whakakotahitanga o ngā hononga raupapa me ngā hononga whakarara. Ko tōna hanganga paerewa ko: tuatahi, honoa ētahi LED i roto i te raupapa hei hanga i tētahi peka, kātahi ka honoa ngā peka raupapa maha i roto i te whakarara ki ngā pito e rua o te pūtake hiko taraiwa LED. I runga i te whakaaro he ōrite ngā tawhā o ia LED, ka taea e tēnei aratau hononga te whakarite kia ōrite te ngaohiko o ngā peka whakarara katoa, ā, kia ōrite te iahiko i roto i ia peka raupapa, e kore e whai whakaaro noa ki te painga o te ōrite o te iahiko o te aratau hononga raupapa, engari ka whakaurua hoki ngā āhuatanga pumau o te ara iahiko o te aratau hononga whakarara.
Me mārama ko te painga matua o te aratau whakakotahi raupapa-whakarara ko te whakapai ake i te pono, he mea tino pai mō ngā āhuatanga rama mana-nui me te maha o ngā LED. Ina puta he hapa LED i roto i te peka raupapa, ka pā noa ki te tukunga mārama o taua peka, ā, ka taea tonu e ētahi atu peka te mahi noa. Ki te whakatauritea ki ngā aratau raupapa me ngā aratau whakarara ngāwari, ka tino whakaitihia te whānuitanga pānga hapa. I tēnei wā, ko te nuinga o ngā rama LED mana-nui (pēnei i ngā rama waipuke LED, ngā rama ahumahi me ngā rama keri LED, me ētahi atu) e whakamahi ana i te aratau whakakotahi raupapa-whakarara, e kore e taea anake te whakatutuki i te hiahia mārama mana-nui, engari ka whakarite hoki i te pono o te whakamahinga.
Ko te ariā hoahoa matua o te aratau hononga rarangi ko te "tauutuutu rōpū". Ko tōna hanganga noa ko: hangaia he peka me ngā rama LED e 3 hei rōpū, ā, ka honoa ia rōpū peka ki ngā pito putanga rerekē e toru o te taraiwa, arā, ko Ua, Ub, me Uc. Mai i te tirohanga arorau mahi, ina he noa ngā rama LED e 3 i roto i te peka, ka tukuna te mārama e ngā rama LED e 3 i te wā kotahi; ahakoa ka rahua te whakatuwheratanga o te 1, e 2 rānei ngā rama LED i roto i te peka, ka taea tonu e ngā rama LED e toe ana te mahi noa, kia mōhio ai kei te tukuna te mārama e te kotahi rama LED i roto i ia rōpū.
