I tenei ra, i te wa e whakamahia nuitia ana te mata whakaatu LED, me maarama tatou ki te tikanga o te tiaki.Ahakoa he whakaaturanga LED o roto, o waho ranei, ka puta te wera i te wa e mahi ana.Na, ka whai hua te mahi pāmahana teitei o te whakaaturanga LED?
Ko te tikanga, he iti te kanapa o te whakaaturanga LED o roto, no reira he iti te wera, na reira ka puta te wera.Heoi, he nui te kanapa o te whakaaturanga LED o waho me te whakaputa i te wera nui, me whakamataohia e nga kaiwhakaahua hau me nga kaiwhaiwhai axial.I te mea he hua hiko, ka pa te pikinga o te pāmahana ki tona oranga ratonga.
1. Mēnā ka nui ake te pāmahana mahi o te whakaaturanga LED i te pāmahana kawenga o te maramara, ka heke te kaha o te whakamarama o te whakaaturanga LED, ka kitea te heke o te marama, ka puta he kino.Ko te nui o te pāmahana ka pa ki te whakahekenga o te rama o te mata LED, a ka marama te attenuation.Arā, ka haere te wā, ka heke haere te wherikotanga kia weto.Ko te pāmahana teitei te take matua o te pirau marama me te whakapoto i te ora whakaatu.
2.Rising pāmahana ka whakaiti i te kakama marama o te mata LED.Ka piki ake te pāmahana, ka piki ake te kukū o nga irahiko me nga kohao, ka heke te aputa roopu, ka heke te nekehanga irahiko.Ka piki ake te pāmahana, ka huri te tihi kikorangi o te maramara ki te ahunga ngaru-roa, ka kore e rite te roangaru tukunga o te maramara me te roangaru whakahihiri o te phosphor, ka heke te kaha tangohanga marama ki waho o te mata whakaatu LED ma.Ka piki ake te pāmahana, ka heke te kaha o te phosphor, ka heke te marama, ka heke te kaha tangohanga o te rama o waho o te mata LED.
