Mahi whatu (tohatoha mārama): Te mahi whatu oNgā rama panera LEDKo te nuinga o te wā, ko ngā whakaritenga mahi e pā ana ki te kanapa, te whānuitanga me te tae. E ai ki te paerewa ahumahi hou "Tikanga Whakamātautau LED Semiconductor", ko te nuinga o ngā roangaru tihi whakamārama, te whānuitanga o te hihi hihi, te koki kaha o te māramatanga tuaka, te rerenga mārama, te rerenga hihi, te pai o te mārama, ngā taunga tae, te pāmahana tae e pā ana, te parakore o te tae me te roangaru matua, te taupū whakaatu tae me ētahi atu tawhā. Ko ngā rama panera LED e whakamahia whānuitia ana ko ngā LED ma, te pāmahana tae, te taupū whakaatu tae me te māramatanga he mea tino nui, he tohu nui tēnei mō te āhuarangi me te pānga o te māramatanga, ā, ko te parakore o te tae me te roangaru matua kāore e hiahiatia ana.

Te mahi wera (hanganga): Ko te pai o te rama LED me te hiko e tukuna ana mō te rama tetahi o ngā mea matua i roto i te umanga LED. I taua wā anō, he mea nui te pāmahana hononga PN o te LED me te raruraru whakamarara wera o te whare. Ko te nui ake o te rerekētanga i waenga i te pāmahana hononga PN me te pāmahana tinana rama, ko te nui ake o te ātete wera, ā, ka pau noa te hurihanga o te kaha rama ki te kaha wera, ā, ka pakaru te LED i ngā wā tino kino. Kaua e whakaarohia noa e te kaihanga hanganga pai te hanganga o te rama me te ātete wera o te LED, engari me whakaaro anō hoki mēnā he tika, he huatau, he hou, ā, he pono, he ngāwari te tiaki me te whai hua o te āhua o te rama. Mai i te tirohanga whakaaro, me whakaaro tātou ki te hua mai i te tirohanga a te kaiwhakamahi.

Te Mahi Hiko (Hikohiko): Ki te whakaritea he rama ki tētahi kōtiro, ko te mārama tōna tikanga, ko te hanganga tōna āhua, ko te hikohiko tōna ngākau. (Ko te ataahua me te ahua o ngā wāhine ataahua tonu te mea e kukume ana i te aro o te tangata, me ngā hua anō hoki.) Ki te kore he ngākau o te tangata, kāore he ora. Ki te kore he irahiko o te rama, e kore e waiho hei pūtake hiko. Ka taea hoki e te pūtake hiko pai te whakatau i te roa o te ora o tētahi hua. He uaua ake ngā paerewa me ngā tawhā hiko i ngā hanganga, ā, he nui hoki ngā mahi rangahau me te whanaketanga tōmua. Kei te huri haere ngā au me ngā whakahoutanga hangarau o nāianei i ia rā e haere ana. Me whakapau kaha ngā kaihangarau ki te ako, ki te mimiti, ki te wetewete me te whakamahi i ngā hangarau hou. Ko te whakamahere-mua o te hoahoa hiko, te whakatinanatanga waenga-wā, me te hanganga o te tukanga o muri mai me hanga tuhinga me te hanga raraunga. Koinei hoki te mea tino uaua i roto i te hoahoa. Hei tauira: ko te mahere-mua o te hoahoa hiko, te whakaahuatanga hua, te pūtake whakatakotoranga paerewa, te pūtake whakatakotoranga haumaru, te uara tumanakohanga mahi hiko, ngā whakaritenga tukanga, te aromatawai rauemi mata, ngā tikanga whakamātautau, me ētahi atu me hanga he kōnae pūnaha.
