Te whiriwhiri i te rama matua mō te puni

He aha koe i hiahia ai ki tētahi mea e tika ana rama matua mō te puni, he māmā, he kawe hoki ngā rama matua, ā, he mea nui mō te haereere i te pō, te whakarite taputapu me ētahi atu wā.

1, kanapa ake: ka teitei ake ngā lumens, ka kanapa ake te mārama!

I waho, he mea nui te "kanapa". Hei tauira, i te maunga pō, i te tūhura rānei i te ana, kāore e ranea te kanapa, tera pea ka taka, ka hinga, ka ngaro rānei i tētahi tohu nui; mā ngā "rama" koe e arahi ki tētahi "pōuri". Ki te hiahia koe kia kanapa, me aro koe ki te tawhā o ngā lumens.

(1) Te ine i te kanapa mai i ngā lumens

I roto i te ao, e kīia ana "kanapa, kāore rānei" te mārama, ko te tikanga, e pā ana ki te rerenga mārama. Ko te waeine o te rerenga mārama ko te lumen, e whakaata ana i te kaha kanapa o te pūtake mārama. Ki te hiahia koe ki te hoko i tētahi rama kanapa, me aro tātou ki ngā lumen o tēnei tawhā. Mā te kanapa teitei ka taea e koe te kite mārama i te taiao kei mua i a koe.

(2) Ka nui ake te uara o te lumen, ka kanapa ake te mārama.

Mōngā rama matua o waho me ngā rama, he whanaungatanga pai kei waenganui i ngā lumens me te kanapa: ka nui ake te uara lumen, ka nui ake te rerenga kanapa, ka nui ake te mana kanapa o te pūtake mārama. Hei tauira, heRama matua 1000 lumen he kanapa ake i te Rama matua 300 lumen.

(3) Te kōwhiringa o te kanapa

Ko te teitei ake o te kanapa o te hua, ko te teitei ake hoki o te utu, me whakakotahi me te whakamahinga ake o te tirohanga ina hoko. Ko te 100 lumens he rite ki te mārama o ngā kānara e 8, ko te nuinga o ngā mahi hikoi puni o waho me whiriwhiri he 100 ~ 200 lumens o ngā hua e ranea ana; ko ngā hua rama ohorere iti he 50 lumens pea te nuinga, engari ka taea hoki te whakatutuki i ngā hiahia rama.

Mena he nui ake ngā whakaritenga mō te rama e whai wāhi ana koe ki ngā hākinakina o waho, ka taea e koe te whakaaro ki ngā hua 200~500 lumens. Mena he nui ake ngā whakaritenga, pēnei i te hikoi tere rawa (te oma i te pō), te hiahia rānei ki te whakamārama i tētahi wāhi nui, ka taea e koe te whakaaro ki ngā hua 500 ~ 1000 lumens.

Ko ngā hiahia ngaio, pēnei i te rapunga whakaora, ka taea e koe te whakaaro ki te nui atu i te1000 lumens rama matuaEhara te mārama i te tikanga o tawhiti, me rapu me te mātakitaki i ētahi wā, ko te tumanako ia kei tawhiti ake te mārama, kātahi ka hiahiatia tētahi atu tawhā kua whakahuatia i raro nei.
