Makemake ʻoe e pili ana i ka mālamalama ʻike ʻole i hoʻohana ʻia i nā hana huna a me nā ola o kēlā me kēia lā? E pane nā kukui infrared LED i kāu mau nīnau a pau.
ʻO ke kukui IR LED kahi koho palekana a me ka ikehu no ka nānā ʻana, ka nānā ʻana i nā holoholona hihiu, nā ʻenehana ʻenehana, a pēlā aku. E wehewehe au pehea e hana ai, he aha kona mau pono, a hāʻawi i alakaʻi i ke koho ʻana i ke kukui LED IR kūpono no kāu papahana ma kēia ʻatikala.
He aha ka Infrared LED Lighting?
Hoʻopuka nā kukui uila infrared i ka radiation electromagnetic i ʻike ʻole ʻia e ko mākou mau maka ma 780 nm a 1,000 nm mau hawewe. Hiki i nā kāmeʻa infrared, nā ʻike maka pō, a me nā ʻenekini ke ʻike i kēia radiation e hāʻawi i ka mālamalama. Hiki iā ʻoe ke hoʻohana i kēia mau infrared nā diodes māmā i nā lako ʻike pō e kiʻi i nā kiʻi ʻokoʻa kiʻekiʻe i ka pōʻeleʻele.
Pehea e hana ai nā kukui infrared LED?
Hoʻololi nā kukui Infrared LED i ka ikehu uila i loko o ka spectrum infrared o ke kukui. Hiki i nā kukui IR ke ʻike a hoʻopuka i nā kukuna infrared ma muli o ke kukui ambient i loaʻa e hoʻonui i ka ʻike.
Aia nā IR LED i nā mea semiconductor. Ke hele ka uila i loko o ka semiconductor, e hoʻopili nā electrons i kēia ikehu. A laila hauʻoli lākou a lele i nā pae ikehu kiʻekiʻe. Ma hope o kēlā, hoʻopuka kēia mau electrons i ka ikehu hou i loko o nā paʻi kiʻi kiʻi a i ʻole ka māmā. I ka hihia o nā LED infrared, hāʻule nā kiʻi i hoʻokuʻu ʻia i loko o ka spectrum infrared, ʻoi aku ka nui o ka lōʻihi hawewe mai 780 a 1,000 nanometers. Eia naʻe, ʻaʻole ʻike ʻia kēia e ka maka o ke kanaka akā ʻike ʻia e nā mea ʻike loea.
Pehea ʻoe e ʻike ai me nā kukui LED IR?
Pono ʻoe i nā optics ʻike pō, e like me ke ākea a i ʻole ke kāmela, e ʻike me nā kukui LED IR. Ke nānā ʻoe ma o ka pahupaʻikiʻi i ka mālamalama haʻahaʻa a i ʻole ka pōʻeleʻele holoʻokoʻa, ʻike ʻia kou puni iā ʻoe. Eia naʻe, e loaʻa iā ʻoe kahi hiʻohiʻona monochromatic ma aneʻi.
Nā pōmaikaʻi o nā kukui LED infrared
- Pākē: Hoʻohana ʻia ia no nā kumu like ʻole e like me ka mālamalama, ka ʻike, a me ke kamaʻilio. No ka laʻana, e ʻike ʻoe i nā LED infrared i nā kaohi mamao, nā kāmela palekana, nā ʻenehana ʻenehana, a me nā mea hou aku.
- ʻO ka ikaika o ka ikehu: ʻO nā kukui LED IR e hoʻemi i ka ikehu. Eia kekahi, hoʻololi ia i ka pākēneka kiʻekiʻe o ka uila i loko o ka radiation infrared.
- Durability: E like me ka IR LED e hoʻemi i ka wela a pale i ka haʻalulu a me ka haʻalulu, ʻoi aku ka lōʻihi o kona ola.
- U lona liʻiliʻi Ma muli o ko lākou liʻiliʻi liʻiliʻi, ua hoʻohui ʻia nā LED IR i kahi ākea o nā mea hana.
- Hoʻomaikaʻi i ka palekana a me ka nānā ʻana: Ma nā kūlana haʻahaʻa a i ʻole ka pō, hoʻonui kēia mau kukui i ka ʻike a hāʻawi i kahi ʻike piha o ka wahi i nānā ʻia. Eia kekahi, ʻaʻole ia e hoʻopilikia i ke kaiapuni a i ʻole e huki i ka nānā ke hoʻohana ʻia i nā hana huna.
- Palekana a ʻAʻole Invasive: No ka mea ʻaʻole invasive ka IR LED ma ke ʻano, ʻaʻole ia e hoʻonāukiuki i ka ʻili a i ʻole ka maka. Eia kekahi, loaʻa i nā kukui infrared kokoke i nā mea anti-inflammatory. No laila, hoʻohana ʻia kēia mau mea i nā lāʻau lapaʻau a me ka mālama ʻili.
Hoʻohana i nā kukui LED infrared
- Pūnaehana kamaʻilio: Hoʻokumu ʻia nā ʻōnaehana kamaʻilio fiber optic a me ka uila me nā kukui LED infrared.
- Nā mea hōʻiliʻili barcode: ʻO nā LED IR kuhikuhi i nā lōʻihi nalu infrared ma luna o ka ʻili barcode. Ma hope o kēlā, ana ka mea heluhelu i ke kukui i ʻike ʻia, a hoʻololi ka decoder i ka hoʻokuʻu ʻana i ka ʻikepili. ʻO kēia ke ʻano o ka hoʻohana ʻana o ka barcode scanner i nā LED IR.
- Nā wati akamai: Hoʻohana nā Smartwatch i ka lōʻihi hawewe IR e nānā i ka puʻuwai puʻuwai. ʻO ka LED infrared i hoʻohui ʻia o ka wati e hoʻokuʻu i ke kukui e hele i ka ʻili a komo i nā kīʻaha koko. Ua helu ʻia ka puʻuwai puʻuwai mai ke kukui i hoʻihoʻi ʻia.
- Lapaʻau Lapaʻau: Hoʻohana nā lāʻau lapaʻau e like me nā pulse oximeters i nā kukui LED infrared e helu i nā pae oxygen koko. No ka wehewehe ʻana, ana ia i ka ʻokoʻa ma waena o ka infrared a me ka ʻulaʻula absorption maanei.
- Nā polokalamu kaʻa: I nā kaʻa, hoʻohana ʻia nā LED IR i nā ʻōnaehana ʻike collision, nā ʻōnaehana nānā ʻana i nā mea hoʻokele, etc.
- Nā mea ʻike kokoke: Hiki ke hoʻohana ʻia nā LED IR e like me nā mea ʻike e ʻike i ka neʻe ʻana a me ka hoʻoulu ʻana i nā ʻala. Hiki iā ia ke ʻike i ka ikehu infrared i hoʻopuka ʻia e ke kanaka a me nā holoholona e like me ka wela.
- Nā Mana Mana Mamao: Hoʻohana ʻia ia i nā mana mamao o nā mea uila. Hoʻopuka ka IR LED o ka mamao i nā pulu kukui infrared no ka mea hoʻokipa. Hoʻohana pinepine ʻia nā LED Gallium Arsenide IR no kēia kumu.
- Nā kiʻi paʻi kiʻi palekana: Hoʻohana ʻia nā LED IR mana kiʻekiʻe i ka lens o nā kāmera palekana. No laila, hiki iā ia ke hopu i nā kiʻi IR i nā kūlana kukui ʻole.

Alakaʻi no ke koho ʻana i ke kukui LED IR pono
1. E nānā i kāu koi noi
ʻO ka lōʻihi o ka nalu, ke kihi, ke ʻano o ka beam, a me nā koi mana o nā LED IR e ʻokoʻa ma muli o kā lākou hoʻohana ʻana i nā sensor, nā kamera, nā mana mamao, a pēlā aku.
2. E koho i ka Loihi Hawewe Pono
ʻO 850 nm a me 940 nm ka lōʻihi hawewe maʻamau no nā kukui LED IR. Inā makemake ʻoe i ka mālamalama i ʻike ʻole ʻia e nā maka kanaka, koho i kahi hawewe 940 nm. He mea maikaʻi ia no nā hana hoʻopunipuni. Eia kekahi, inā makemake ʻoe i ka LED IR no nā kumu palekana, a laila kūpono ʻo 850 nm iā ʻoe.
3. E noʻonoʻo i ka ʻoki ʻana i ke kukui (Half-Angle)
E koho i kahi liʻiliʻi kihi kukuna o 10-20 degere ke makemake ʻoe e kau i kahi kikoʻī. Eia kekahi, pono ʻoe i kahi kihi beam nui o 30-60 degere e hoʻomālamalama i kahi ākea ākea.
4. E nānā i nā koi mana
Pono ʻoe e koho i kahi mana kiʻekiʻe no ka nānā lōʻihi a me kahi mana haʻahaʻa no ka nānā ʻana i ka mamao pōkole. No ka laʻana, hiki i nā mana mamao ke hana me nā au 20-100 mA, akā pono nā kāmela kiaʻi 500 mA a i ʻole.
5. Mai poina i ka Weatherproofing a me ka Waterproofing
E hoʻohana i nā LED IR pale ʻole a me ka wai no ka hoʻohana ʻana i waho. E koho i kahi ʻIke helu IP o IP66 no kāu kelepona. Hōʻike ka huahelu mua i ke kūʻē i ka lepo. Ma ka pālākiō o 0-6, ʻo 6 ke ʻano o ka paʻa lepo. Ma hope o kēlā, hōʻike ka helu ʻelua i nā waiwai pale wai. Ma ka pālākiō o 0-8, ʻo 8 ke ʻano o ka pale piha i ka wai.
Pehea e koho ai ma waena o 850 nm a me 940 nm?
Pono ʻoe e koho i ka nalu o nā IR LED ma muli o kāu hoʻohana kikoʻī. No ka wehewehe ʻana, ʻoi aku ka maikaʻi o nā kukui LED 940 nm IR i nā hana huna. ʻOi aku ka maikaʻi no ka nānā ʻana i nā holoholona hihiu no ka mea ʻike ʻole ʻia e ka hapa nui o nā holoholona. ʻOiai kēlā, i kekahi manawa hāʻawi ia i kahi pōkole o ka ʻike ma mua o 850 nm.
Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o nā kukui LED 850 nm IR no nā noi ʻike pō, ka hopu holoholona, a me nā kāmera palekana. Hāʻawi ia i kahi kiʻi kiʻi maikaʻi aʻe i nā kāmeʻa IR me ka lōʻihi o ke ola. Eia naʻe, hoʻopuka ia i kahi ʻulaʻula e ʻike ʻia e nā maka kanaka.
Hoʻomaʻamaʻa kukui LED infrared
Hoʻohana ʻia nā kukui LED infrared i nā lāʻau lapaʻau no nā kūlana olakino. No ka laʻana, hiki i kēia ʻano hana māmā palekana ke hōʻoluʻolu i ka ʻeha, hoʻemi i ka ʻāʻī o ka ʻiʻo, hoʻomaikaʻi i ke kahe koko, hoʻolalelale i ke kaʻina hana ho'ōla, etc.
Eia kekahi, komo ke kukui infrared kokoke i nā papa ʻili hohonu. A laila e hoʻomoʻa ka mitochondria o ka cell i kēia ikehu a hoʻoikaika i nā hana olaola. ʻO kēia lāʻau lapaʻau ʻole e hoʻoikaika i ka ʻōnaehana pale o kou kino.
Ka palena o IR LED Light
- Hiki i nā ʻōnaehana IR LED ke hana i nā kiʻi ʻeleʻele a keʻokeʻo.
- Hoʻopilikia ʻia ka maikaʻi o nā sensor IR e nā mea like me ka ua, ka lā, ka noe, ka lepo, etc.
- ʻAʻole hāʻawi ka hoʻoili IR i kahi ākea ākea.
- Hōʻike nā mea ʻeleʻele i kahi hapa liʻiliʻi o ke kukui IR. ʻAʻole lawa i nā manawa a pau ka ʻike ʻana i kēlā mea.
