ʻO nā kukui LED kahi ʻano hoʻohiki o ke kukui hou i nā wahi lehulehu a me nā home. Kaulana lākou i kēia manawa ma muli o kā lākou hoʻohana ʻana i ka ikehu. I ka 1927, ua hoʻokumu ʻia ka LED e O.V. Eia naʻe, ʻo Losev, ua komo nā kukui LED i ka mākeke kūʻai wale nō i nā makahiki 1960. Ua hakakā nā mea hoʻomohala e kiʻi i nā LED o nā kala like ʻole, a i nā makahiki 1990, ua haku ʻia nā kukui keʻokeʻo, i hiki ke hoʻohana ʻia i ke ola o kēlā me kēia lā. He palekana paha ka hoʻohana ʻana i nā u kukui LED i kou home? No ka pane ʻana i kēia nīnau, pono ʻoe e ʻike he aha ka hopena o ke kukui LED i ke olakino kanaka.

ʻO ka ʻino o nā LED i nā lālā o ka hihiʻo

I mea e hōʻoia ai i ka maikaʻi o nā kukui LED, ua lawe ʻia e kekahi ʻepekema Sepania. Ua hōʻike ʻia kā lākou hopena e hoʻonui ai i ka ikaika o ka pāhawewe pōkole, nona nā kiʻekiʻe o ka viola, a ʻo ka polū hoʻi, ke kukui. Hoʻopilikia lākou i nā ʻokana o ka hihi, ʻo ia hoʻi, hiki iā lākou ke hōʻino i ka retina o ka maka. Hiki i ka radiation radiation ke hōʻeha i nā ʻano aʻe:

  • photothermal - hiki i ka hoʻonui ʻana o ka mahana;
  • photomekanical - ka hopena o kahi nalu haʻalulu o ke kukui;
  • photochemical - hoʻololi i ka pae macromolecular.

Ke hoʻohaunaele ʻia nā hunaola o ka retinal pigment epithelium, ʻike ʻia nā maʻi like ʻole, me kēia e alakaʻi ai i ka nalo ʻana o ka ʻike. Ua hōʻoia nā ʻepekema i ka hoʻomālamalama ʻana o ke aniani uila i kēia mau pūnaewele ke alakaʻi i ko lākou make. ʻO ke kukui keʻokeʻo a me ka ʻōmaʻomaʻo hoʻi he mea ʻino, akā i ka liʻiliʻi, ʻaʻole ʻino ka ʻulaʻula. ʻOiai ʻo kēia, hāʻawi ka hoʻomālamalama polū i nā huahana kiʻekiʻe a hoʻomaikaʻi i ka noʻonoʻo.

ʻAʻole koi ka poʻe loea i ka hoʻohana ʻana i nā kukui LED i ke ahiahi a me ka pō, keu hoʻi ma mua o ka hiamoe, no ka mea hiki ke kōkua i ka hoʻomohala ʻana i nā maʻi aʻe.

Eia hou, ua kāohi ʻia ka huna o melatonin i ke kino.

ʻO ka ʻino o LED i ke kūlohelohe

Ma waho o ke kino o ke kanaka, he hopena maikaʻi ʻole ka kukui LED i ke kaiapuni. Loaʻa i kekahi mau LED nā hunaahi o arsenic, kēpau, a me nā mea ʻē aʻe. He mea ʻino ke hoʻopili i nā mahu e kū ana ke haki ke kukui LED. E hoʻolei iā ia me nā mīkina lima pale a me kahi pale maka.

ʻOiai nā hemahema maopopo, hoʻohana ʻino nā kukui LED ma ke ʻano he waiwai waiwai o ke kukui. ʻAʻole lākou e hoʻohaumia i ke kaiapuni ma mua o nā kukui i loaʻa i ka mercury. I mea e hōʻemi ai i ka hopena maikaʻi ʻole i ke olakino, ʻaʻole pono ʻoe e hoʻohana mau i nā LED, e hoʻāʻo e hōʻalo i ka pae polū, a pale hoʻi i ka hoʻohana ʻana i nā kukui i mua o ka moe.
