Ua Loaʻa iā UVLED ʻEpekema UVLED kēia mau ʻano

ʻO UVLED, ʻo ia hoʻi, UV light light diode, he ʻano LED. ʻO ia kahi puʻupuʻu LED kiʻekiʻe me kahi puʻupuʻu LED kiʻekiʻe me kahi ʻāpana o 200nm a 450nm. ʻO nā kumu nui o ka UVLED nā helu aʻe: 1. ʻO ka mīkini hoʻokuʻu ʻana o UVLED: ʻO ka volta hope o ka puʻupuʻu PN he mea hiki ke pale. I ka emi ana o ka volt bias, e laha ka nui o na mea hoouka ma na wahi P a me N i kekahi aoao. No ka mea, ʻoi aku ka nui o ka neʻe ʻana o ka uila ma mua o ka neʻe ʻana o ka ea acupoint, hoʻolaha ka nui o ka uila i ka wahi P, e hana ana i kahi injection o kahi mea lawe liʻiliʻi o ka wahi P. Hoʻohui ʻia kēia mau electrons mai ke ana ma ke kumukūʻai, a hoʻokuʻu ʻia ka ikehu i loaʻa i ka wā composite ma ke ʻano o ka ikehu māmā. ʻO kēia ke kumu o ka PN knot glow. 2. ʻO ka maikaʻi o ka hoʻokuʻu ʻana i nā kukui UVLED: ʻO ka mea maʻamau i kapa ʻia ʻo ka quantum efficiency o waho o ka ʻāpana, ʻo ia ka quantum efficiency o ka ʻāpana a me ka huahana o ka pono o ka ʻāpana. 3. Nā hiʻohiʻona optical UVLED: Hāʻawi ʻo UVLED i kahi kukui monochrome nui me kahi semi-ākea nui. E like me ka emi ʻana o ka ikehu o ka semiconductor me ka mahana, piʻi ka lōʻihi hawewe i hoʻokuʻu ʻia me ka piʻi ʻana o ka mahana a piʻi me ka piʻi ʻana o ka mahana. 4. ʻO nā hiʻohiʻona ʻepekema thermal UVLED: Ma lalo o kahi manawa liʻiliʻi, ʻaʻole maopopo ka piʻi ʻana o ka mahana o LED. Inā kiʻekiʻe ka mahana o ke kaiapuni, ʻulaʻula ka lōʻihi o ka nalu nui o UVLED, e emi ana ka ʻōlinolino, a lilo ka like ʻole o ka luminous a me ke kūlike. 5. ʻO ke ola UVLED: ʻO ka hana lōʻihi o UVLED e hoʻoulu ai i ka ʻelemakule, ʻoi aku hoʻi no nā UVLED kiʻekiʻe, ʻoi aku ka koʻikoʻi o ka pilikia o ka pohō māmā. Ke ana ʻana i ke ola o UVLED, ʻaʻole lawa ka hoʻohana ʻana i ka pōʻino o ke kukui e like me ke ola UVLED. Pono e hoʻohana ʻia e kuhikuhi i ke ola o LED me ka pākēneka o ka pākēneka o ka attenuation UVLED. Nui nā hiʻohiʻona o UVLED, akā ʻo ka hōʻuluʻulu nui ʻo ia nā helu aʻe: 1. ʻAʻohe hopena solvent-greenhouse 2. He kūpono ia i ka mālama ʻana i ke kaiapuni 3. ʻĀina hana ʻole me ka pollution 4. Hakamaka5. Oʻohmea6. Loaʻa i nā huahana nā hana kūikawā 7. Koh8. ʻai ʻoe 9. Konmake10. Meiwa oha11. Mae poʻi ichng12. ʻO ke ʻano like ʻole, hiki ke hoʻololi, hoʻololi wikiwiki i ka huahana. Ma muli o ka nui o nā hiʻohiʻona a me nā hiʻohiʻona o UVLED, ua kau ʻo ia i ke kumu no ka hoʻohana hope ʻana o UV solidification.
