Ko te pūhiko hiko o te puku LED he kaitahuri hiko e huri ana i te pūhiko ki tētahi ngaohiko me te iahiko motuhake hei akiaki i te LED kia tukuna te mārama. I raro i ngā āhuatanga noa: ko te whakaurunga o te mana puku LED kei roto ko te auau hiko ngaohiko teitei AC (arā, te hiko tāone), te ngaohiko iti DC, te ngaohiko teitei DC, te ngaohiko iti me te ngaohiko teitei. Auau AC (pēnei i te putanga o te whakawhiti hiko), me ētahi atu.

–E ai ki te tikanga taraiwa:

(1) Momo au pumau

a. He pumau te iahiko putanga o te ara iahiko taraiwa iahiko pumau, engari ka rerekē te ngaohiko DC putanga i roto i tētahi awhe me te rahi o te ātete kawenga. Ka iti ake te ātete kawenga, ka iti ake te ngaohiko putanga. Ka nui ake te ātete kawenga, ka teitei ake te ngaohiko putanga;

b. Kāore te ara iahiko au pumau e wehi i te ara iahiko poto o te kawenga, engari he tino rāhuitia te whakatuwhera katoa i te kawenga.

c. He mea tino pai mō te whakamahi i tētahi ara iahiko taraiwa au pumau hei taraiwa i ngā rama LED, engari he tino teitei te utu.

d. Kia aro ki te uara ātete mōrahi me te uara ngaohiko e whakamahia ana, e whakawhāiti ana i te maha o ngā rama LED e whakamahia ana;

(2) Momo whakahaere:

a. Ina whakatauhia ngā tawhā rerekē i roto i te ara iahiko whakahaere ngaohiko, ka pumau te ngaohiko putanga, engari ka rerekē te iahiko putanga i te pikinga, i te hekenga rānei o te kawenga;

b. Kāore te ara iahiko whakahaere ngaohiko e wehi i te whakatuwheratanga o te kawenga, engari e tino rāhuitia ana te whakapoto i te ara iahiko o te kawenga.

c. Ka peia te rama LED e tētahi ara iahiko taraiwa whakau-ngaohiko, ā, me tāpiri he ātete e tika ana ki ia aho kia whakaatu ai ia aho rama LED i te kanapa toharite;

d. Ka pāngia te kanapa e te huringa ngaohiko mai i te whakatikatika.

–Te whakarōpūtanga o te mana taraiwa LED:

(3) Puku pāorooro

He maha ngā whakamahinga LED e hiahia ana ki ngā mahi whakaiti i te kanapa, pērā i teWhakamārama rama LEDte whakaiti rānei i te kanapa me te rerekētanga o te rama hoahoanga. Ka taea te whakatutuki i te mahi whakaiti mā te whakarerekē i te kanapa me te rerekētanga o te rama LED. Mā te whakaiti noa i te iahiko o te taputapu ka taea te whakarerekē i teRama LEDte tukunga, engari ko te tuku i te LED kia mahi i raro i te āhua o te iahiko kua whakatauria ka puta he maha ngā hua kino, pērā i te he o te tae. Ko tētahi atu huarahi hei whakarerekē i te iahiko ngāwari ko te whakauru i tētahi kaiwhakahaere whānui o te pāorooro (PWM) ki roto i te taraiwa LED. Kāore te tohu PWM e whakamahia tika hei whakahaere i te LED, engari hei whakahaere i tētahi pana, pērā i te MOSFET, hei whakarato i te iahiko e hiahiatia ana ki te LED. Ko te tikanga ka mahi te kaiwhakahaere PWM i tētahi auau pumau, ā, ka whakarerekē i te whānui o te pāorooro kia ōrite ki te huringa mahi e hiahiatia ana. Ko te nuinga o ngā maramara LED iahiko e whakamahi ana i te PWM hei whakahaere i te tukunga mārama LED. Kia kore ai te tangata e rongo i te kanapa kitea, me nui ake te auau o te pāorooro PWM i te 100HZ. Ko te painga matua o te whakahaere PWM ko te tika ake o te iahiko whakaiti i roto i te PWM, e whakaiti ana i te rerekētanga tae ina tukuna te mārama e te LED.

(4) Puku AC

E ai ki ngā momo whakamahinga, ka taea hoki te wehewehe i ngā puku AC ki ngā momo e toru: te buck, te boost, me te converter. Ko te rerekētanga i waenga i te puku AC me te puku DC, i tua atu i te hiahia ki te whakatika me te tātari i te AC whakauru, kei reira anō te raruraru o te wehenga me te kore wehenga mai i te tirohanga haumaru.

Ko te taraiwa tāuru AC te mea e whakamahia nuitia ana mō ngā rama whakahou: mō ngā rama tekau PAR (Parabolic Aluminium Reflector, he rama noa i runga i te atamira ngaio), ngā pūangi paerewa, me ētahi atu, ka mahi i te 100V, 120V, 230V AC rānei. Mō te rama MR16, me mahi i raro i te tāuru 12V AC. Nā ētahi raruraru uaua, pērā i te kaha whakaiti o ngā triac paerewa, ngā whakaiti taha mua me ngā whakaiti taha muri, me te hototahi ki ngā whakawhiti hiko (mai i te ngaohiko raina AC ki te whakaputa 12V AC mō te mahi rama MR16). Ko te raruraru o te mahi (arā, te mahi kore-kanapa), nō reira, ki te whakaritea ki te taraiwa tāuru DC, he uaua ake te mara e uru ana ki te taraiwa tāuru AC.

Ka tukuna te pūhiko hiko AC (puku matua) ki te puku LED, mā roto i ngā mahi pēnei i te whakahekenga, te whakatikatika, te tātari, te whakaū i te ngaohiko (te whakaū rānei i te iahiko), me ētahi atu, hei huri i te hiko AC ki te hiko DC, kātahi ka whakarato i ngā LED e tika ana mā roto i te ara iahiko puku e tika ana. Me nui te whai huatanga o te huringa o te iahiko mahi, me iti te rahi me te utu iti, ā, i te wā kotahi ka whakatauhia te raruraru o te wehenga haumaru. Me whakaaro ki te pānga ki te whatunga hiko, me whakatau hoki ngā take pokanoa hikohiko me te tauwehenga mana. Mō ngā LED iti me te reo-mana, ko te hanganga ara iahiko pai rawa atu he ara iahiko whakawhiti rere kotahi-pito wehe; mō ngā tono mana-tiketike, me whakamahi he ara iahiko whakawhiti piriti.

–Te whakarōpūtanga o te wāhi tāutanga hiko:

Ka taea te wehewehe i te mana taraiwa ki te pūtake mana o waho me te pūtake mana kua hangaia ki roto, e ai ki te tūranga tāutanga.

(1) Pūnaha hiko o waho

E ai ki te ingoa, ko te pūtake hiko o waho hei tāuta i te pūtake hiko ki waho. I te nuinga o te wā, he teitei te ngaohiko, he tūponotanga haumaru tēnei ki te tangata, ā, me whai pūtake hiko o waho. Ko te rerekētanga ki te pūtake hiko kua hangaia ki roto, he anga tōna, ā, he mea noa ngā rama tiriti.

(2) Pūnaha hiko kua whakauruhia

Kei roto i te rama te pūtake hiko. I te nuinga o te wā, he iti noa te ngaohiko, mai i te 12v ki te 24v, kāore he tūponotanga mō te haumaru o te tangata. He rama pūangi kei tēnei mea noa.
