Te tawhiti o te hihi o te rama matua

Ka pāngia te tawhiti mārama o ngā rama LED e ētahi āhuatanga, tae atu ki ēnei engari kāore e herea ki:

Te mana me te kanapa o te rama matua LED. Ko ngā rama matua LED he kaha ake, he kanapa ake, ka nui ake te tawhiti o te māramatanga. Nā te mea he nui ake te mana me te kanapa, he nui ake te mārama e tukuna ana, ka haere ki tawhiti atu i te wāhi. Tērā pea ka rerekē te kanapa o ngā rama matua LED o te mana kotahi i runga i ngā kaihanga me ngā tikanga whakaputa rerekē.

Te hoahoa me te tukanga hanga o te rama matua LED. Ka whakaata me te arotahi pai ake te rama matua LED i te mārama, ka taea ai e ia te mahi pai ake i runga i te tawhiti. I taua wā, ka taea e te tukanga hanga matatau te whakarite i te whai huatanga me te pumau o ngā pīrere LED, ka pā kino ki te tawhiti o te hihi. Hei tāpiri, ko ngā wāhanga pēnei i te peihana whakaata me te ira o te rama matua ka pā ki te pānga mārama me te tawhiti o te hihi.

He pānga anō hoki ngā āhuatanga taiao ki te tawhiti whiti o ngā rama matua LED. Hei tauira, ina whakamahia he rama matua LED i te rangi pō mārama, tera pea ka tawhiti ake te tawhiti whiti i te rangi kohu, kapua rānei. Hei tāpiri, ko ngā āhuatanga mārama o te taiao e whakamahia ana te rama matua LED ka pā pea ki te mahi whakahohe me te kanapa o te rama matua LED, ka pā pea ki tōna tawhiti whiti.

Hei whakarāpopototanga, ko te tawhiti o te hihi oNgā rama matua LEDKāore i te tino pumau, engari he maha ngā āhuatanga e pāngia ana. I te wā e whiriwhiri ana, e whakamahi ana hoki i ngā rama LED, me whiriwhiri e koe te tauira tika me te taumata kanapa e ai ki ngā hiahia me ngā āhuatanga taiao kia pai ai te pānga rama me te whakamahinga haumaru. Me tirotiro te pukapuka hua mō te tawhiti rama motuhake, me whakahaere rānei i ngā whakamātautau mara hei whakatau.
