Ko ngā rorohiko o te LED i whakamāhinga i te ara e ngā umanga me ngā kaiwhakamahi e whakamāhi ana i ngā rorohiko, i tuku i te whānui o ngā kōrero mō te tāwhai i ngā tae, ā, kāore he rorohiko tuatahi e whai ai i tēnei. Ko ngā rorohiko o tēnei wā o te LED e whakamāhi ana i ngā uara o ngā kōpū pūngao kia hanga i tēnei ao o ngā tae, mai i ngā mā pure ki ngā tae kaha rawa atu, me ngā mea katoa i waenganui i ānei. Ko te mātauranga i ngā tae e whai ai ngā rorohiko o te LED he mea matua mō tēnei tangata e whakamāhi ana i ngā rorohiko, ahakoa mō ngā whakamātautau ā-āhua, ngā whakamātautau mō te mahi i ngā rākau, i ngā taiao hāpaiti.
Te whai hāngai o te hanga whakamātautau mātāwaka kia whakamāhinga i ngā tae rerehua mai i te wāhi e tū nei o ngā pūtake o ngā pūkenga, i ngā roa o te tāwhai. I te whakamātau i ngā diode mātāwaka e whakamāhinga ana i ngā tae matua rerekē, me te whakamārama i ō rātou mātāwhānui i te wāhi e tū nei, ka taea e ngā kaiwhakamātautau te whakamāhinga o ngā tae katoa e whakaaro ana. Ko tēnei te take matua o ngā rārangi RGB o tēnei wā, o ngā whakamāhinga mātāwaka e whakamāhinga ana i ngā tae, me ngā whakamāhinga ā-hapori mō ngā roa o te tāwhai e whakamāhinga ana i ngā rārangi o tēnei wā.
Te hāhā o te whakamāhinga tae i ngā rārangi mātāwaka
Me pēhea ngā diode mātāwaka e whakamāhinga ana i ngā tae matua
Ko ngā LED e katoa he rākau hāngā whakamātautau e whakamātautau ana i te āhua o te whiti, ā, ko te roa o te tāwhai e whakamātautau ana i te rākau hāngā me ōna pūhanga āhua. Ko ngā rākau hāngā mā, he rākau hāngā mātāmua, e whakamātautau ana i ngā roa o te tāwhai i te 620–630 nanomete, ko ngā rākau hāngā kākāriki i te 500–530 nanomete, ā, ko ngā rākau hāngā kikorangi i te 450–470 nanomete.

FAQ
He whakamātautau ake a ngā rākau LED i ngā tae kāore i kitea i te rere kōrero?
Āe, ko ngā pūnaha whakamātautau ā-huinga (solid state lighting) e whakamahinga ana i ngā huinga o te wāhi (LED) e whakamātautau ana i ngā tae rānei, pērā i te magenta, e kore nei e noho i te rākau o te āniwaniwa. Ko ēnei tae he whakarewa o ngā roa tāwhai ā-huinga ā-LED i ngā ara e whakamātautau ana i ngā whakaahua e kore nei e noho i te mātātoko tāwhai māmā. Ko ngā pūnaha whakamātautau ā-huinga e whakamāhi ana i te whakarewa RGB, ā, ka taea e ngā huinga o te wāhi (LED) te tūhono ki tēnei wāhi katoa o ngā tae e kitea ana.
He aha te mea e whakamārama ai i te tika o ngā tae o ngā pūnaha whakamātautau ā-huinga?
Ko te tika o ngā tae he whāinga o te kounga o ngā māteriahi ā-huinga, o te rere o te whakapāki i ngā phosphor, me te whakamārama o ngā hāngā whakamātautau i ngā huinga o te wāhi (LED). Ko ngā pūnaha huinga o te wāhi (LED) e whakamāhi ana i ngā whakamārama matua o te Whakamārama Tae (CRI) e whakamāhi ana i ngā tae i te tika. Ko ngā kaiwhakamahi o ngā pūnaha whakamātautau ā-huinga e whakamārama ai i ēnei whakamārama, ā, e āwhina ana i ngā kaihoko kia whiriwhiri i ngā pūnaha e tātari ana i ngā whakamārama o te tika o ngā tae mō ngā mahi pērā i te whakaahua, te whakamārama, i ngā mahi hauora.
He heke ā-tae ngā pūnaha whakamātautau ā-huinga e whakamāhi ana?
Ahakoa he whānui ngā wāhi o te tirohanga e whakamātautia ana e ngā rorohiko LED, he rerekē ngā whānui o ngā rorohiko LED takitahi i ngā roa tātai. He tāwhai i ngā rorohiko maha te whakamārama i ngā kōkōrangi me ngā magenta, ā, he pūkenga matatau te hāngai. Ka whanake tonu te hanga rorohiko, ā, ka whakamāua ēnei here ngā pūnaha pūkaha, ahakoa he nui ake te utu i tēnei wā i ngā whāinga o te whakamārama kōkōrangi.
