ʻO nā ʻāpana o nā kukui LED: semiconductor material chip, keʻokeʻo keʻokeʻo, papa kaapuni, epoxy resin, uea kumu, pūpū.ʻO ke kukui LED he chip electroluminescent semiconductor material, i hoʻōla ʻia ma ka bracket me ke kala kala a i ʻole ke keʻokeʻo keʻokeʻo, a laila hoʻopili i ka chip a me ka papa kaapuni me kahi uea kālā a i ʻole uea gula.Hoʻopaʻa ʻia ka puni me ka resin epoxy no ka pale ʻana i ka uea i loko.Hana, hoʻokomo hope i ka pūpū, no laila he maikaʻi ka hana seismic i ke kukui LED.

ʻO ka LED light-emitting diode kahi mea semiconductor solid-state e hiki ke hoʻololi i ka ikehu uila i kukui ʻike.Hiki iā ia ke hoʻololi pololei i ka uila i māmā.ʻO ka puʻuwai o ka LED he puʻupuʻu semiconductor, ua hoʻopili ʻia kekahi ʻaoʻao o ka chip i ke kākoʻo, ʻo kekahi ʻaoʻao ka pole maikaʻi ʻole, a ʻo ka ʻaoʻao ʻē aʻe e pili ana i ka pou maikaʻi o ka lako mana, i hoʻopili ʻia ka chip holoʻokoʻa. e ka epoxy resin.

ʻO ke kumu hoʻomāmā o nā kukui LED

Ke hele nei ke au i ka wafer, ʻo nā electrons i loko o ka semiconductor N-type a me nā puka o ka semiconductor P-type e kuʻi ikaika a hui hou i loko o ka papa kukui e hana i nā kiʻi, e hoʻopuka ana i ka ikehu ma ke ʻano o nā photons (ʻo ia hoʻi. , ka malamalama a na mea a pau e ike ai).ʻO nā semiconductors o nā mea likeʻole e hana i nā kala likeʻole o ke kukui, e like me ke kukuiʻulaʻula, ke kukui'ōmaʻomaʻo, ke kukui uliuli a pēlā aku.

Ma waena o nā papa ʻelua o nā semiconductor, nā electrons a me nā lua e hui pū a hui hou a hana i nā photons polū i loko o ka papa kukui.ʻO kahi hapa o ke kukui polū i hana ʻia e hoʻokuʻu pololei ʻia ma o ka uhi fluorescent;ʻo ke koena e paʻi i ka uhi fluorescent a hui pū me ia e hana i nā kiʻi melemele.Hana pū ka photon uliuli a me ka photon melemele (mixed) e hana i ke kukui keʻokeʻo
