Pehea e hana ai ka LED i ka malamalama?

ʻO Electroluminescence ke kaʻina hana e hana ai nā LED (Light Emitting Diodes) i ka mālamalama. Penei ka hana ana:

1-Semiconductor Material: Hoʻohana ʻia kahi mea semiconductor, maʻamau ka hui ʻana o nā mea e like me ka phosphorous, arsenic, a i ʻole gallium, e hana i kahi LED. ʻO ka n-type (negative) wahi, ka mea i oi aku o electrons, a me ka p-type (maikaʻi) wahi, ka mea i nele o electrons (puka), i hanaia i ka wa e doped ka semiconductor me na haumia.

2-Electron-Hole Recombination: Hoʻoikaika ʻia nā electrons mai ka ʻano n-type i ka ʻāpana ʻano-p ke kau ʻia ka uila ma luna o ka LED. Hoʻohui hou kēia mau electrons me nā puka ma ka māhele p-type.

3-Photon Emission: Hoʻopuka ʻia ka ikehu ma ke ʻano he māmā (photons) i kēia kaʻina hana hou. Hoʻoholo ka bandgap ikehu o ka mea semiconductor i hoʻohana ʻia i ka hue o ke kukui i hoʻokuʻu ʻia. Hiki ke kukui i nā kala like ʻole e pili ana i ka mea.

4-Efficiency: No ka mea, ua hoʻololi ʻia ka hapa nui o ka ikehu i nā LED i māmā ma mua o ka wela-he pilikia maʻamau me nā ʻōpuʻu incandescent maʻamau-ʻoi aku ka maikaʻi o nā LED.

5-Encapsulation: Ma ka hoʻopili ʻana i ka LED i kahi resin a i ʻole lens, hoʻomaikaʻi pinepine ʻia ke kukui e hoʻopuka ai. Hiki i kēia ke kōkua i ka hoʻopuehu ʻana i ke kukui a hoʻomaikaʻi maikaʻi.

I ka hoʻohālikelike ʻana i nā ʻano kukui maʻamau, hiki i kēia ala ke hāʻawi i nā LED e hāʻawi i ke kukui ikaika a me ka hoʻohana ʻana i ka ikehu liʻiliʻi.

ʻOiai ka lōʻihi o ko lākou ola a me ka maikaʻi, hiki i nā kukui LED ke loaʻa i nā pilikia maʻamau, e like me:
1) Hoʻololi ʻana o ke kala: ʻO nā kukui kūpono ʻole i kahi wahi hiki ke hopena mai ka hoʻololi ʻana o ka mahana ma waena o nā pūʻulu o nā kukui LED.

2) Flickering: Ke hoʻohana ʻia me nā hoʻololi dimmer incompatible a i ʻole nā ​​pilikia me ka lako mana, e ʻā ana kekahi mau kukui LED.

3) Ka wela nui: Hoʻemi ʻia ka wela o nā LED ma mua o nā kukui maʻamau, akā ʻaʻole lawa ka wela wela hiki ke hoʻoulu i ka wela, hiki ke hōʻemi i ke ola o nā puʻupuʻu.

4) Nā pilikia hoʻokele: I mea e hoʻomalu ai i ka mana, pono nā kukui LED i nā mea hoʻokele. Hiki ke ʻōlinolino, pōwehiwehi, a pau ka hana ʻana o ke kukui inā hana hewa ka mea hoʻokele a haʻahaʻa paha.

5) Hoʻohālikelike Hoʻohālikelike: Hiki mai nā pilikia hana no ka mea ʻaʻole kūpono kekahi mau kukui LED me nā hoʻololi dimmer o kēia manawa.

6) Limited Beam Angle: Hiki i nā kukui like ʻole ke hopena mai nā kukui LED me kahi kihi beam palena ʻole, ʻaʻole kūpono ia no nā noi he nui.

7) Ke kumu kūʻai mua: ʻOiai ʻo nā kukui LED e mālama i ke kālā ma mua o ka manawa, hiki iā lākou ke kūʻai aku i ke kūʻai mua ʻana ma mua o nā puʻupuʻu maʻamau.

8) Nā Manaʻo Kaiapuni: Inā ʻaʻole e hoʻokuʻu pono ʻia, hiki ke hoʻopōʻino i ke kaiapuni ke kiʻekiʻe o nā mea ʻino e like me ke kēpau a i ʻole arsenic i loaʻa i kekahi mau kukui LED.

9) Hoʻololi i ka maikaʻi: Nui nā huahana LED ʻokoʻa ma ka mākeke, ʻaʻole i hana ʻia lākou a pau i nā kūlana like, e hoʻololi ai i ka lōʻihi a me ka hana.

10) ʻAʻole hiki ke hana maikaʻi i kekahi mau ʻōpuʻu LED, ʻoiai nā mea i hana ʻia no nā ʻōpuʻu incandescent maʻamau.

Ke koho ʻana i nā mea kiʻekiʻe kiʻekiʻe, e hōʻoia i ka hana ʻana me nā ʻōnaehana o kēia manawa, a e like me nā ʻōlelo hoʻonohonoho pono pinepine e hoʻonā i kēia mau pilikia.

Nui nā ʻāpana māmā e koho ai ma ka mākeke i kēia manawa, e like meCOB stripCSP strip, ʻokoʻa me kaSMD kaha, e leka uila iā mākou inā makemake ʻoe i nā laʻana no ka hoʻāʻo.
