Hangarau whakatika wherikotanga aunoa mo te whakaaturanga LED tae-katoa

Ko nga mata whakaatu LED he tino noa i roto i te ao me te kawe mai i te maha o nga waatea ki o tatou oranga.I te mea ko te kanapa o te mata whakaatu LED e kore e taea te whakarereke me te rama ambient, he raruraru o te whakaatu kore marama i te awatea, he kanapa ranei i te po na te tino kanapa.Mena ka taea te whakahaere i te kanapa, ehara i te mea ka taea te whakaora i te kaha anake, engari ka marama ake te paanga whakaatu o te mata whakaatu.
Ko te 01led he puna marama matomato, ko tana painga nui ko te kaha o te rama
Na te whanaketanga me te ahunga whakamua o te aoiao rauemi, ka tino pai ake te kakama i roto i nga tau 10 e whai ake nei;iti te kohi pūngao, roa te ora o te ratonga, rauemi tukurua, me te kore parahanga ki te taiao.Ahakoa te mutunga o te tiimata o to tatou whenua, i nga tau tata nei kua timata ano te mahi rangahau me te whakawhanaketanga me nga kaupapa here me te tautoko ahumahi.Ka whakatauritea ki te rama rama, he rereke te rerekee o te LED: ko te kanapa o te rama he rite tonu ki te rahi o te au whakamua e rere ana i roto i te diode whakaemi rama.Ma te whakamahi i tenei ahuatanga, ka inehia te kanapa o te taiao a tawhio noa e te pukoro whatu, ka huri te kanapa o te kanapa i runga i te uara ine, ka mau tonu te awe o nga huringa kanapa o te taiao a tawhio noa, me te hanga i nga tangata ki te mahi harikoa.Ehara tenei i te hanga i te taiao whakamarie me te kanapa tonu, engari ka tino whakamahi i nga rama taiao me te tino whakaora i te kaha.Na reira, he mea tino nui te rangahau mo te hangarau whakamarumaru whakaahuru LED.
02 nga kaupapa matua
Ka whakamahia e tenei hoahoa te pou ki te tuku raraunga me te tikanga matawai haupae ki te mohio ki te tuhinga whakaatu LED, whakaahua ranei.Ka honoa tenei tikanga me te ara iahiko taputapu ki te whakatutuki i te kaupapa o te kanapa o te mata whakaatu.Whakamahia te ahuatanga tairongo o te photoresistor ki te marama ambient, kohia te huringa o te rama ambient, huri hei tohu hiko ka tukuna atu ki te miihini miihini kotahi-marama, ka mahia e te tukatuka maramara kotahi te tukatuka tohu, me te whakahaere i te tauwehenga mahi o te putanga. Ngaru PWM e ai ki tetahi ture.Ka taapirihia he ara iahiko whakahuri ngaohiko i waenga i te rorohiko moroiti maramara kotahi me te mata whakaatu arataki kia mohio ai koe ki te whakarereketanga kanapa o te mata whakaatu e te rorohiko miihini maramara kotahi.Ka whakamahia te ngaru PWM kua whakaritea ki te whakahaere i te iahiko whakaahuru ngaohiko whakawhiti ki te whakatika i te ngaohiko whakauru o te mata whakaatu, ka mutu ka mohio ki te mana kanapa o te mata whakaatu.
03Ahuatanga
He ara iahiko mana wherikotanga urutau mo te mata whakaatu diode marama, e tohuhia ana ko: he taputapu whakauru uara tatūkē mahi, he porotiti me te whakatairite i te rahi, ka tatauhia e te porotiti me te huringa mahi te taputapu whakauru uara tatūkē. ka whakatairitehia ki te uara tatūkē o te huringa mahi ki te kaiwhakarite rahi hei whakahaere i te uara whakaputa o te kaiwhakarite.
04LED urutaunga pūnaha dimming hoahoa pūmārō
Ko te kanapa o te LED he rite ki te ia e rere ana i roto i te ahunga whakamua, me te rahi o te waa whakamua ka taea te whakatika hei whakatika i te kanapa o te LED.I tenei wa, ka whakatikahia te kanapa o te LED ma te whakatika i te aratau mahi o naianei, te aratau whakarereketanga whanui ranei.Ko te mea o mua he awhe whakatikatika nui, he pai te raina, engari he nui te kaha o te kaha.No reira he iti noa te whakamahi.Ko te tikanga whakahuri i te whanui o te putere e whakamahi ana i te auau teitei ake ki te huri i nga rama, ko te huringa whakawhiti kei tua atu i te awhe ka kitea e te tangata, kia kore ai e rongo te tangata ki te noho o te stroboscopic.Kia mohio ki te ahua o te ahua o te rama rama.
