I. Kupu Whakataki: Ngā Tūponotanga Huna o te Whakaataata me ngā Wāhanga Matua o ngā Kaiwhakamahi
1.1He aha te pānga o te kimokimo o ngā rīpene rama LED?
Ko te kanapa e pā ana ki te āhuatanga e tere haere ana te kanapa o te rama LED, ā, e rerekē haere ana i ia wā, i ia wā. Ko tōna uho ko te mārama me te pōuri e puta mai ana i te iahiko taraiwa koretake. Tērā pea kāore e kitea tēnei rerekētanga e te kanohi tahanga, e puta rānei hei kanapa motuhake. E ai ki te paerewa a te International Commission on Illumination (CIE) TN 006-2016, ina neke ake te auau kanapa i te 125Hz, kāore e taea e te kanohi tangata te kite, engari tera pea ka pā kino te kanapa huna.
1.2 Ngā Tūponotanga Tūpono o ngā Pānga Stroboscopic ki te Oranga me te Hauora
Tērā pea ka pāngia ngā kanohi e te kimo iti-auau (100Hz – 120Hz) e te ngenge o ngā kanohi, te ānini, te maroke o ngā kanohi me ētahi atu mamae. Mā te roa o te wā e pāngia ana e te kimo ka nui ake te taumahatanga ki ngā kanohi. Ahakoa kāore e kitea e te kanohi tahanga, ka puta he rārangi me ngā here pōuri i te wā e pupuhi tere ana, ā, ka pāngia hoki te manawataki koiora o te tinana, ka aukati i te whakaputanga o te melatonin, ka pāngia hoki te kounga o te moe. Mō te hunga he mate pāwera ki te hihi o te rā, ka nui ake pea te tūponotanga o ngā whakaekenga mate haurangi nā te kimo iti-auau. Mō ngā tamariki, mā te roa o te wā e pāngia ana e te kimo ka tere ake te haere o te myopia.
1.3 He aha te take e kimokimo ai te nuinga o ngā rīpene rama?
He maha ngā rīpene rama LED kei te mākete e tūpono ana ki te kimokimo. Ka taea te whakarāpopoto i ngā take matua ki ngā wāhanga e toru: Tuatahi, te whakahaere utu. Ka whakaitihia e ngā hua iti te maha o ngā pūnga tātari, ā, ka whakamahia he maramara taraiwa iti te utu, kāore e taea te pehi i ngā ngaru hiko; Tuarua, he ngoikore te hototahi ki te whakaitiiti. He iti rawa ngā auau whakaitiiti PWM tuku iho, inā koa i roto i ngā āhuatanga iti-kanapa, ka puta he kimokimo mārama; Tuatoru, he hapa hoahoa. Kāore te pūtake hiko me te rīpene rama i te ōrite tika, ā, kāore te ngaronga ngaohiko o te taura roa e utua, ka hua ake te korenga o te pumau o te iahiko.
II. Tātaritanga Matua: Ngā Take Taketake o te Whakakā o te Rīpene Rama LED

Ko te nuinga o ngā rīpene rama LED me huri te mana matua 220V AC ki te pūtake hiko 12V/24V DC. Mena kāore i te tino tika te hoahoa o ngā wāhanga whakatikatika, tātari, me te whakahaere iahiko pumau, ka arahi ki ngā rerekētanga o te iahiko, ā, ka puta te kimo.
2.2 Ngā Momo E Rua o te Whakakākā Noa me ō Rātou Take
Te kimomi auau-iti (100Hz – 120Hz): Ko te nuinga o tēnei ka puta mai i te korenga o te tātari i te ngaohiko i muri i te whakatikatika, ā, nā ngā wāhanga AC toenga ka puta ai ngā rerekētanga o te iahiko. He mea kitea noa tēnei i roto i ngā pūhiko hiko iti te utu kāore he pūnga hiko hiko, kāore rānei he iti te kaha hiko. Mēnā ka roa te whakamahi i aua pūhiko, ka ngāwari te ngenge.
Te kanapa auau-tiketike (>1kHz): He mea noa ake tēnei i roto i ngā āhuatanga whakaitiiti PWM. Ahakoa ngā tohu PWM auau-iti ((<200Hz) kāore e kitea e te kanohi tahanga ka kitea pea ngā raruraru i te wā e pupuhi ana. Tērā pea ka puta he haruru i ētahi hua nā te pokanoa o te haruru, ka nui ake te āhua o te kimo.
2.3 Ngā Āhuatanga Āwhina Tāpiri
Haunga ngā take matua o te taraiwa, ka taea hoki e te roa o te taura, te hototahitanga o te pūnaha whakaitiiti, me te pokanoa hikohiko (EMC) te whakararu i te kanapa. Hei tauira, ki te neke atu i te 5 mita ngā rīpene rama 12V me te kore he utu hiko, ka kore e pumau te puku iahiko pumau nā te ngaronga hiko; kāore i te whai mahi whakaitiiti auau-teitei ngā kaiwhakahaere kore-mārama, ka raru pea ngā rīpene rama.
