I roto i te mara oNgā rīpene rama LED, ko te rerekētanga matua i waenga i te "IC whakauru" me te "IC o waho" kei roto i te tūranga tāutanga o te maramara whakahaere (IC), e whakatau tika ana i te aratau whakahaere, ngā āhuatanga mahi, te uaua o te tāutanga me ngā horopaki e tika ana mō ngā rīpene rama. Ka taea te whakataurite mārama i ngā painga me ngā rerekētanga i waenga i ngā mea e rua mai i ngā āhuatanga maha, penei:
Rīpene rama IC kua hangaia: kua whakauruhia te IC me te LED, e whakangawari ana i te hoahoa me te tāutanga
Ko te āhuatanga matua o te rīpene rama IC kua hangaia ki roto ko te tākai i te maramara whakahaere (IC) me te pītiti rama LED katoa (pērā i ngā tauira noa WS2812B, SK6812, me ētahi atu), arā, "kotahi te pītiti rama e rite ana ki te kotahi IC", me te kore e hiahiatia he maramara whakahaere o waho. Ko ōna painga e whakaatuhia ana i roto i ngā āhuatanga e whai ake nei:
1. Hanganga kiato me te tāutanga ngāwari
Ka whakauruhia e te IC kua hangaia ki roto ngā "pīrere LED + IC whakahaere" ki roto i te kete kotahi, ka angiangi ake, ka māmā ake, ka angiangi ake te hanganga whānui o te rīpene rama. Kāore he take ki te rāhui i ētahi atu wāhi mō te tāutanga IC, he mea tino pai mō ngā Wāhi whaiti me ngā āhuatanga iti (pērā i ngā whāriki rama tāonga, ngā taputapu petipeti, me ngā rama whakapaipai moroiti).
I te wā e tāuta ana, kāore he take ki te whakapiri motuhake i te IC o waho. Me whakapiri noa, me waea rānei ki te huarahi tuku iho o ngā rīpene rama, ka tino whakaiti i te uaua o te hanganga. Ahakoa te hunga tīmata ka taea te whakahaere tere.
2. Mana whakahaere pai, e tautoko ana i te "mana tae kotahi-ira"
I te mea he IC motuhake kei ia pīrere LED, ka taea e ia te whakatutuki i te kanapa motuhake me te whakatikatika tae o ngā pika takitahi (ngā pīrere LED) (pērā i ngā pānga hihiri pērā i te wai rere, te rōnaki, me te whakaaturanga tuhinga), ka whakarato i te whakaaturanga tirohanga whai kiko ake. He pai mō ngā whakaaturanga e hiahia ana ki ngā pānga rama kua whakatikatikaina (pērā i te rama taiao, te whakamārama rama mō ngā peita whakapaipai, me te rama taipitopito atamira).
3. Mā te waea māmā ka whakaitihia te maha o ngā pūwāhi hapa
E toru noa ngā waea e hiahiatia ana mō ngā rīpene rama IC kua hangaia: "VCC (pai), GND (kino), me te DAT (raina tohu)" hei whakahaere (kei roto i ētahi tauira ngā raina karaka CLK), ā, kāore he take ki te whakarite i ētahi atu puna hiko, raina tohu rānei mō ngā ics o waho. He iti te maha o ngā waea, ā, he māmā ake te ara iahiko.
Mā te whakaiti i ngā "pūnga hononga i waenga i te IC o waho me ngā pīrere LED", ka heke iho te tūponotanga o ngā hapa i puta mai i te koretake o te waea me te korenga o te whakapā, ā, ka teitei ake te pumau.
4. Ka taea te whakahaere i te utu, ā, he pai mō ngā āhuatanga tauine waenga me te iti
Ahakoa he paku teitei ake te utu mō tētahi "IC LED + IC kua hangaia ki roto" i tērā o ngā pīrere rama noa, ka kore e hiahiatia ngā utu hoko me te whakapiri motuhake mō ngā ics o waho, ā, ka ngāwari ake te whakahaere i te utu whānui. He tino pai mō ngā mahi roa waenga me te iti, me ngā mahi puranga waenga me te iti (pērā i te whakapaipai kāinga me ngā whakapaipai arumoni iti).
Rīpene rama IC o waho: Kei waho motuhake te IC, ka taea te urutau ki ngā āhuatanga kaha me ngā āhuatanga uaua.
Ko te āhuatanga matua o te rīpene rama IC o waho ko te whakaurunga motuhake o te maramara whakahaere (IC) me ngā pīrere LED – he pīrere IC noa ngā pīrere (pērā i ngā pīrere 5050, 2835), ko te IC whakahaere ka whakapiri motuhake ki tētahi tūranga motuhake i runga i te papa PCB o te rīpene rama (pērā i te WS2811, TM1914, me ētahi atu). I te nuinga o te wā, "kotahi te IC e whakahaere ana i ngā pīrere LED maha" (hei tauira, kotahi te IC e whakahaere ana i ngā pīrere LED e toru). Ko ōna painga ka kitea nuitia i roto i ngā āhuatanga e whai ake nei:
1-He hototahi ki te mana teitei, ā, he pai ake te tohatoha wera
Kua wehea te IC o waho mai i ngā pīrere rama LED, kia kore ai e puta te raruraru "kohikohi wera" o te IC me ngā pīrere rama i roto i te kete kotahi. He tino pai mō ngā rīpene rama mana-nui (pērā i ngā mea he mana neke atu i te 12W ia mita me ngā āhuatanga rama kanapa-nui).
Ka taea e ngā ics o waho te whakamarara i te wera mā roto i tētahi wāhi nui ake o te pepa parahi i runga i te papa PCB, ka taea rānei te hoahoa i ētahi atu hanganga whakamarara wera hei whakaiti i te mōrearea o te hekenga o te mahi, o te kino rānei i puta mai i ngā pāmahana teitei. He pai ake tō rātou pumau mō ngā tono kawenga teitei (pērā i ngā rama arumoni me ngā pouaka rama pānuitanga o waho).
2-Mana whakahaere ngāwari, e tautoko ana i te "whakarōpūtanga o ngā pīrere rama maha"
Ko ngā ics o waho e tautoko ana i te "kotahi IC e whakahaere ana i ngā pīata rama maha" (pēnei i te 3 rama/IC, 6 rama/IC), ā, ka taea te whakatutuki i te "whakahaere tae mā te rōpū" - he pai mō ngā horopaki he iti ngā whakaritenga mō te "whakahaere tae kotahi-ira" engari me "ngā pānga hihiri ā-rohe" (pēnei i ngā rama whakarārangi whare o waho, ngā rama horoi pakitara nui).
Ko ētahi o ngā ics o waho (pēnei i te WS2811) e tautoko ana i ngā tāurunga ngaohiko teitei ake (pēnei i te 12V/24V). Ki te whakatauritea ki te tāurunga 5V noa o ngā ics kua hangaia, he iti ake te whakaiti ngaohiko i te wā e tukuna ana i tawhiti, ā, he pai mō ngā tono rīpene rama tino roa (pēnei i ngā rīpene rama o waho neke atu i te 10 mita).
3-He iti te utu tiaki, he ngāwari hoki te whakakapi
Kua wehea te IC o waho mai i ngā pīrere rama. Mēnā ka hē tetahi IC, ko te IC hapa anake me whakakapi motuhake, me te kore e hiahiatia te whakakapi i te whiri rama katoa (mēnā ka hē te IC o roto, me whakakapi katoa te kete "pīrere rama + IC"). Waihoki, ki te hē te mahi a ngā pīrere LED, kāore he take ki te whakakapi i te IC me ērā atu. I te wā tiaki, ka iti ake te utu o ngā wāhanga, ā, he ngāwari ake te whakahaere.
Mō ngā whakamahinga nui me ngā whakamahinga roa (pērā i ngā toa hokohoko me ngā kaupapa o waho), he mārama ake te painga utu o ngā mahi tiaki i muri mai.
4-Hototahi kaha, e tika ana mō ngā pūnaha whakahaere uaua
He whānui ake te kōwhiringa tauira o ngā ics o waho. Ko ētahi ics o waho kounga teitei e tautoko ana i ngā tere tuku tohu teitei ake me ngā hongere whakahaere maha atu, ā, e hototahi ana ki ngā pūnaha whakahaere uaua (pēnei i te DMX512, te kawa Art-Net), e tika ana mō ngā horopaki hangarau nui (pēnei i ngā pūnaha rama atamira, ngā rama wāhi nui), ā, ka taea te whakatutuki i te whakahaere hononga tukutahi o ngā rīpene rama maha.
Mena he iti te wāhi e hiahiatia ana, he pai ngā pānga hihiri, me te ngāwari o te tāutanga (pēnei i te rama taiao o te kāinga, te whakapaipai papamahi), me whiriwhiri ngā rīpene rama IC kua hangaia ki roto i te whare hei kaupapa matua.
Mena he mea nui ngā whakaritenga mō te mana nui, mō ngā tawhiti, mō ngā āhuatanga o waho, mō te ngāwari rānei o te tiaki i ngā wāhanga o muri mai (pēnei i te rama o ngā whare o waho me ngā toa hokohoko), me aro nui ki ngā rīpene rama IC o waho.
He maha ngā momo rama LED kei roto i ngā rama MX tae atu ki te rama COB/CSP,rīpene pika hihiri,he rama neon flex,he rīpene hiko teitei me te mīhini horoi pakitara.Whakapā maiki te hiahia koe i ngā tauira hei whakamātautau!
