Hono LED. He aha i taea e ohie?

E whakaahua ana tēnei tuhinga pehea ki te whakatinana i te hononga o LED, e mano Me ki te ū ki te tikanga ki te whakarite mahi tika o ngā pūrere. Rerekē o te hononga.

Hono LED. He aha i taea e ohie?

inaianei kua mohiotia whānuitia enei mea iti. kua rongo nga tangata katoa te arahina rama, rama, tupare me ētahi atu kanapa, kakahu Britain me tākaro. E ratou maha painga me te painga whakaritea ki topuku marama tikanga, engari i reira he āhuatanga o te tono. Na me pehea e hiahia ana koe ki te mahi i te hononga o LED?

Hoki te whakamahi tika o te whakaaro Me ki tino whai i te torutoru whakaritenga ohie, a ka kore ratou e tukua tetahi raruraru, a ka mahi mo te wa roa.

Tino nui - e kore e wareware i te ture taketake e rua:

1. Ko nga LED he whakaaro Semiconductor me whai he kawe ia kotahi-ara, ranei, i roto i nga kupu atu, kia kawea te hononga o te LED i ki te wehenga tawhiti tika (rite ina hono koutou e kore e taea e te pūhiko whakapoauau te "+" me "-"). Kore, ko te arahina ko rānei tahuna ranei e kore e whakamarama ake.

te mana 2. Pūrere nāianei. He aha te mea te nāianei hiko, e kore te mea e tika ana ki te whakamārama, engari te meka e kia kia rerekē tona uara, e hiahia ana koe ki te mohio. Ko te nui e rerengia ana i roto i te ara iahiko i whakaritea e te mehua o tona resistance. Ko te taua mea tupu ina whakatuwhera koe i te tap - ki te whakatuwhera koe i te reira i te iti, ka rere i te wai i te awa angiangi, e rerengia ana e nui resistance wai tap; ki te whakatuwhera koe i te reira tino, ka rere i te wai jet kaha, ātete inu he warou iti.

Hoki te tikanga kia rere i te mahi tika, me te tonu o te arahina i roto i te tetahi uara o nāianei, te auau i whakaritea e nga āhuatanga o te arahina. Ki te ko te nāianei nui rawa, te wae wera. He ōrite ki te mea e, e tamata tatou ki te tuku i te wai ki te pēhanga i roto i te ngongo wai rapa kikokore tenei. Ki te kore te mea kaha rawa te pēhanga, ka whai wā ki te haere na roto i te ngongo wai te wai, a ka waiho nga mea katoa pai. Ki te he reira nui rawa, ngongo wai noa pakaru. Ko te taua te mea e pa ki a arahina. Ki te nui ake te nāianei te uara e hiahiatia, te wae wera.

Ko te nui o te nāianei whakahaere te parenga. He mea tika ki te mahara e taea te hanga te hononga arahina ki te pūtake ngaohiko i roto i anake te parenga. e kore he aha te mea, me te nui ātete kia whakamahia mō te mahi noa o te arahina te kaupapa o tēnei tuhinga. Ki te hiahia koe ki te hanga i te marama ake pūrere, ka whiwhi nui kōrero i roto i te taonga mo te kōwhiringa o te parenga. Na he mau iti whakapiringa mo tūhono tahi nga mea timatanga.

pā katoa o te runga ake ki te take o honotanga whakaaro ki te pūtake ngaohiko DC, arā, pākahiko, pūhiko te tahi mea rite taua ranei. A, no te ngana ki te hono LED ki te whatunga kāinga, arā, AC pūtake ngaohiko, he mea e tika ana ki te whakamahi i ato'a i te ngōhiko rectifier, e kore e wareware e pā ana ki tenei, no te Ture 1.

Heoi, i reira kia kia he āhuatanga ina e hiahia ana koe ki te whakamahi i LEDs maha wā kotahi. I roto i tenei take, i reira e rua ara ki te whakatinana i tenei hiahia.

Ki te hiahia koe ki te tiki, mo te tauira, atu rama, te whakamahi i te hononga whakarara o LED. Na ka ko tata te taua mea katoa, ki te puna ngaohiko i te wa ano hono e rave rahi whakaaro anake. Kaua e wareware kia tupu te hononga o ia o ratou i roto i te parenga.

Ki te mea e tika ana ki te mahi i te tahi mea, ano he tupare, e hiahia ana koe he LED hononga rangatū. I roto i tenei take, i hono te taua momo o ngā pūrere hono ki tetahi ki tetahi kia ki te haunga o mua me muri. Ka rite ki te hua, whiwhi tatou he mekameka e kua rua pito free - pai, me te kino. Na kei te mahi tenei mekameka kua rite te LED kotahi, a taea te hono mā te parenga ki te pūtake ngaohiko.
