He aha i kiia ai te rama LED hei rama mō te hangarau penapena hiko?

I te huringa o te wā, ka tīmata te tangata ki te mārama ake ki te maumau pūngao e pā ana ki ngā pūangi rama mura tuku iho. Ahakoa te angitu nui ki te whakarato rama, i pāngia ngā pūangi rama mura e te ngoikoretanga o te huri i te nuinga o te pūngao ki te wera, kaua ki te mārama, ā, he iti noa iho te whai huatanga o te pūngao.

I tēnei wā tino hira, ka tū whakamua tētahi kaihanga ko Edison tōna ingoa me te whai i te penapena pūngao me te wairua auaha, ka tīmata ki te mahi whakapai ake i te rama hiko. Whai muri i ngā whakamātautau maha, ka hangaia e ia tētahi momo rama hiko hou - te pūrama rama incandescent. Nā tēnei mahi hou i tino whakapai ake te whai huatanga o te rama, engari kāore tonu i taea te whakatika i te take matua o te moumou pūngao.

Heoi, i te wā tonu e raru ana te iwi i tēnei raruraru, ka puta te hangarau LED (Light Emitting Diode). I whakamahia e ngā rama LED ngā rauemi semiconductor hei tuku mārama, kaua ki te whakamahana i ngā miro whakarewa hei whakaputa mārama, ā, nā reira i huri ai te umanga rama. Kāore i te mea he pai ake te whai huatanga o te pūngao o ngā rama LED, me te huri i te nuinga o te pūngao hei mārama kaua ki te wera, engari he roa hoki te ora me te mārama o te tukunga mārama, ā, koia te mea hou o te umanga rama.

I te whanaketanga tonu me te rongonuitanga o te hangarau LED, ka tīmata te whakamahinga whānui o ngā rama LED i roto i ngā momo mara. Mai i ngā rama whare ki ngā rama arumoni, mai i ngā rama motuka ki ngā mata pouaka whakaata, i puta he hurihanga nui i roto i te umanga rama i te hangarau LED. I āta mōhio te iwi kāore i te āwhina noa ngā rama LED ki te penapena hiko engari he pai ake hoki ngā pānga rama, ā, ka noho koia te mea tino pai o te umanga rama.

Nā te whanaketanga hou o te hangarau LED, ehara i te mea kua whakarerekē noa i te āhua o te umanga rama i tēnei wā, engari kua kawea mai hoki he tumanako hou me ngā āheinga ki te tangata. I ēnei rā, e whakamahia whānuitia ana ngā rama LED i roto i ngā momo mara, e whakarato ana i ngā otinga rama e whai hua ana ki te hiko, e pai ana ki te taiao, ā, e whai hua ana hoki. Mā te āhua hurihuri o tēnei hangarau ka ārahi tonu i te umanga rama ki mua, ka kawea mai he heke mai kanapa ki a tātou.

E ai ki te kōrero, "Mā te mārama o te hurihanga e whakamārama te heke mai." Kua tīmata kē te hurihanga o te hangarau LED, ā, e tino tumanako ana mātou ki te kawe mai i tētahi āpōpō kanapa ake ki a mātou.
