E mārama ana koe ki te "lumen" e tika ana kia mōhiotia e te rama?

I roto i te hoko owahoupokongā ramamepuniHe maha ngā wā ka kitea te kupu "lumen" i roto i ngā rama, e mārama ana koe?

Ngā Lumens = Te Putanga o te Mārama. I roto i ngā kupu māmā, ko ngā Lumens (e tohuhia ana e te lm) he ine i te nui katoa o te mārama e kitea ana (ki te kanohi tangata) mai i te rama, i te pūtake mārama rānei.

Ko te nuingawaho noapunimārama, rama matua, rama rāneiKo ngā rama rama LED te mea nui, he iti ake te kaha e whakamahia ana, nō reira he iti ake te whakatauranga watt. Nā tēnei, kāore e taea te whakamahi i ngā watt i whakamahia hei ine i te kanapa o te pūangi rama, nō reira kei te huri ngā kaihanga ki ngā lumens.

Ko te Lumen, he waeine ā-tinana e whakaahua ana i te rerenga o te mārama, ka whakatauria e te "lm", he whakarāpopototanga mō te "lumen". Ko te teitei ake o te uara lumen, ko te kanapa ake o te pūangi. Mēnā kāore koe i te tino mōhio ki ngā tau lumen, mā tēnei tūtohi o ngā rama incandescent ki te LED ka hoatu he tohutohu ki a koe. Arā, ki te hiahia koe ki tētahi LED ka taea te whakatutuki i te pānga o tētahi rama incandescent 100W, whiriwhiria he LED 16-20W, ā, ka whiwhi koe i te kanapa ōrite.

I waho, e ai ki ngā momo mahi rerekē, me rerekē ngā taumata lumen, ka taea e koe te tirotiro i ngā raraunga e whai ake nei: puni pō: tata ki te 100 lumen hikoi pō, whiti (me te whakaaro ki ngā huringa o te rangi pēnei i te ua me te kohu): 200~500 lumen mō te oma ara, ngā reihi pō rānei: 500~1000 lumen rapu me te whakaora pō ngaio: neke atu i te 1000 lumen

Kia tūpato i te wā e whakamahi anangā rama o waho(ina koa ko ērā he nui ngā lumens), kaua e anga atu ki ngā kanohi o te tangata. Ka kino pea ngā kanohi o te tangata ki te nui rawa te kanapa o te mārama.
