He aha ke kumu e make ai ka chip LED keʻokeʻo?

Hoʻohana wale nā ​​mea hana he nui i nā mea liʻiliʻi a haʻahaʻa e hoʻohaʻahaʻa i ke kumukūʻai o nā kukui i mea e hoʻowalewale ai i nā mea kūʻai aku. Ua piʻi ka nui o nā hoʻopiʻi maikaʻi e pili ana i nā kukui WHITE LED panel i nā makahiki ʻelua i hala ma muli o kēia. ʻO ka melemele ʻana o ka ʻili o nā kukui panel kekahi o lākou, a he ʻino loa. E kamaʻilio mākou e pili ana i ke kumu Hip keʻokeʻo LED chip  Ail. Me ka hoʻopaneʻe hou aku, e luʻu pono kāua.

He aha keʻokeʻo LED chip ?

Hiki ke hoʻokō ʻia ka hana kukui keʻokeʻo me nā LED WHITE ma nā ala ʻelua. ʻO ke ala RGB ka mea mua, a ʻo ke ala phosphor ka lua. ʻO ke ala phosphor ka mea i hoʻohana pinepine ʻia i ka ʻāpana kukui. Hoʻokumu ka ʻenehana phosphor i kahi pūʻolo WHITE LED e hoʻoulu i ke kukui keʻokeʻo ma ka uhi ʻana i kahi uliuli keʻokeʻo LED chip me ka phosphor melemele.

Hiki ke hoʻokō ʻia ka hana kukui keʻokeʻo me nā LED WHITE ma nā ala ʻelua. ʻO ke ala RGB ka mea mua, a ʻo ke ala phosphor ka lua. ʻO ke ala phosphor ka mea i hoʻohana pinepine ʻia i ka ʻāpana kukui.

Ma ka hoʻohui wale ʻana i nā kukui ʻulaʻula, ʻōmaʻomaʻo, a me nā ʻulaʻula uliuli i nā ʻāpana kūpono, hana ʻia ke kukui keʻokeʻo me ka hoʻohana ʻana i ka ʻenehana RGB.

Hoʻokumu ka ʻenehana phosphor i kahi pūʻolo WHITE LED e hoʻoulu i ke kukui keʻokeʻo ma ka uhi ʻana i kahi uliuli keʻokeʻo LED chip  me ka phosphor melemele. Hāʻawi ka papa fluorescent melemele i ke kukui uliuli i hana ʻia e ka keʻokeʻo LED chip  e hele i loko, e hana ana i ke kukui keʻokeʻo me kahi hui o nā blues a me nā photon melemele.

Ma ke kiʻekiʻe o ka puʻupuʻu, hoʻokumu ʻia kahi diode māmā (LED) me nā mea semiconductor i hoʻopaʻa ʻia e hana i kahi hui p-n. Ma ka hoʻohana ʻana i kahi au i mua i ka hui ʻana, hiki i kekahi ke hoʻoikaika i nā electrons e neʻe mai ke ʻano n-type conduction band i ka p-type conduction band. ʻO kēia hoʻohui hou ʻana he kaʻina radiative i ka nui o nā manawa, e hopena i ka hana ʻana o kahi photon me ka lōʻihi hawewe i hoʻoholo ʻia e ka bandgap o ka mea.

Ma hope o ka hoʻohālike ʻana o kahi LED KEʻO  wafer, ʻoki ʻia a ʻoki ʻia, a hoʻopili ʻia ka mea make i hana i ka wafer a hoʻopaʻa ʻia. Pono e hoʻopili i ka LED KEʻO  i nā alakaʻi me ka hoʻohana ʻana i nā uwea maikaʻi loa, i hana mau ʻia me ke gula, i mea e hoʻohua ai i ke au i mua e pono ai e hoʻomālamalama mai ka LED KEʻO.

No ke aha mai keʻokeʻo LED chip s Make?

ʻIke pinepine nā LED WHITE i kekahi o ʻelua mau ʻano hemahema: holomua a pōʻino paha. ʻO ka hāʻule ʻole o kahi LED KEOKEO  ʻoi aku ka hopena ma muli o ka emi ʻana o ka manawa ma mua o ka hoʻololi koke ʻana, me ka liʻiliʻi loa. ʻO ka hāʻule ʻole, i ka maka o nā mea kūʻai aku, ʻaʻole ia he kūlana ʻelua mau mokuʻāina akā he wahi kūʻokoʻa ma kahi hoʻomau o nā pae hana. Wahi a ka noiʻi, hiki i ka maka o ke kanaka ke ʻike i ka hoʻololi ʻana a hiki i ka 30 pakeneka o ka luminous flux ma mua o ka emi ʻana o ka puka o ke kukui e like me ia. Ma muli o kēia, ʻo ka hapa nui o nā mea hana e wehewehe i ke ola o kahi hāmeʻa ma ke ʻano o ka hāʻule ʻana o ka luminous flux puka ma lalo o 70 pakeneka o ka waiwai i loaʻa iā ia ma mua.

Akā naʻe, ʻaʻole kēia manaʻo ʻaʻole e hiki mai kahi pōʻino. ʻOiaʻiʻo, hiki ke hoʻopau ʻia kekahi o kāu mau mea hana i ka hana pono i kekahi manawa e piʻi like me ka paʻakikī o nā kūlana hana. Aia nō naʻe nā hana e hiki ai iā ʻoe ke hana e hōʻemi i ka hopena o kēia mau kumu a hoʻonui i ka manaʻo e ʻae ʻia kāu noi.

Nā hemahema waiwai

WHITE LED  ʻO ka hana a me ke ola e pili ana i ka maikaʻi o nā mea. ʻO ka hoʻohui hou ʻana o ka electron-hole e hoʻopōʻino ʻole ke kino inā he nui nā hemahema o ka mea. Hana ʻia ka hapa nui o nā kukui keʻokeʻo keʻokeʻo keʻokeʻo ma luna o nā substrate sapphire i uhi ʻia me GaN. ʻO ke kānana mai ka lattice mismatch e hoʻoulu i ka hoʻokaʻawale ʻana o ka threading. Hoʻolaha ʻia nā māwae maikaʻi mai ke kiʻiʻoniʻoni GaN a i ka ʻāpana hana, no ka mea i hoʻopōʻino ʻole ʻia. E emi ana ka puka o ke kukui ke pi'i ka palaho nonradiative. Hiki i ka Thermocycling ke hoʻolaha i kēia mau hemahema.

ʻAe ʻia ke kahe ʻana o ka leaka mai nā hemahema o ke kūkulu ʻana. Hiki ke hana a hoʻolaha paha i nā pōʻino. Hoʻohaʻahaʻa ka nui defect i ka puʻupuʻu haʻihaʻi, pili i ka hana.

Hiki i ke au ki'eki'e ke ho'opilikia i ka 'ao'ao p o ka hui. Ua hoʻohaʻahaʻa ʻia ke koʻikoʻi uila ultraviolet WHITE LED ma mua o ke kaumaha wela. Zhuhai Tianhui Electronic Co., Ltd.   He kūpono ke kukui keʻokeʻo keʻokeʻo no nā noi ultra-mālamalama. Hiki i ka mea i kau ʻia ma luna ke hoʻopaʻa i 2.8 A i mua o kēia manawa no 900 lm puka.

Ke kalaiwa i ka LED KEOKEO

Ke kalaiwa i ka LED KEOKEO  hiki ke hōʻino i ka huahana a me ke ola. No nā noi ʻōlinolino kiʻekiʻe, e kuhikuhi i kahi mea e like me kēia LED keʻokeʻo keʻokeʻo, hiki ke hoʻopuka i 900 lm ma 2.8 A.

WHITE LED  ʻaʻole i kaupalena ʻia nā hewa i ka media hana. Mālama ka Epoxy encapsulate i ka make, akā hiki ke hoʻopilikia. Hiki i ka mea absorptive ke hoʻololi i ka makū a i ʻole nā ​​mea kemika caustic i ka make i loko o nā wahi haʻahaʻa a ʻino paha. Hiki i nā mea hoʻopili ʻino ke hana i nā pōkole a i ʻole overvoltage. Hiki i ka passivation ke hōʻemi i kēia hopena, akā pono e pale ʻia nā mea hana i nā kūlana wela a me ka haʻahaʻa.

Nā hewa uila

ʻO ka Electromigration, kahi kaʻina hana maʻamau i hoʻonui ʻia e ka haʻahaʻa a i ʻole ke ʻano maʻamau, hiki ke hana i nā filament mai nā metala e like me ke kālā i loko o ka paʻi i hoʻohana ʻia no ka hoʻopili ʻana i nā LED mauna i nā papa. Hōʻalo i nā LED i hoʻopaʻa ʻole ʻia.

WHITE LE D ʻike ʻia i ka hoʻokuʻu electrostatic kiʻekiʻe hiki ke hāʻule i ka pōʻino. He mea maʻamau ka puʻu kiʻekiʻe-voltage. Hiki iā ʻoe ke hoʻonui iā ʻoe a hiki i ka 1.5 kV ka hele ʻana ma o kahi lumi kākela, ma muli o ka haʻahaʻa a me nā kāmaʻa. Hiki i kēlā haʻalulu ke lanakila i ke kūpaʻa electrostatic material semiconductor ke hāʻawi ʻia i kahi make. Hiki i ka hoʻomehana kūloko mai ka hoʻokuʻu ʻana ke hoʻoheheʻe i ka media hoʻoikaika, e hoʻopōkole ana.

Kahi e kuai ai Keʻokeʻo keʻokeʻo LED chip  ʻOi aku ka lōʻihi

Zhuhai Tianhui Electronic Co., Ltd.  he kūlana kiʻekiʻe UV Nā mea hana LED  ʻoihana kūikawā i ka hoʻomaʻemaʻe ʻana i ka ea UV WHITE LED, hoʻomaʻemaʻe i ka wai, UV WHITE LED drive paʻi ʻana, uv Keʻokeʻo LED diode , uv   Ka Huwai , a me na mea e ae. Loaʻa iā ia kahi noiʻi akamai a me ka hoʻomohala ʻana a me nā limahana hoʻolaha e hoʻolako i nā mea kūʻai aku me ka UV WHITE LED drive Arrangement, a ua loaʻa pū kāna huahana i ka ʻae ākea ākea.

Ua lilo ʻo Tianhui Hardware i ʻāpana o ka UV WHITE LED drive puʻupuʻu me kahi pūʻulu hana piha, ka maikaʻi kūlike a me ka lōʻihi, a me nā kumukūʻai haʻahaʻa. ʻO nā ʻāpana he UVA, UVB, a me UVC mai ka pōkole a i ka lōʻihi a me ka ʻike piha o ka UV Radiation mai ka haʻahaʻa a i ka mana kiʻekiʻe.
