Ka taea te whakamahi i te Papa Hanga Sapphire Tauira (PSS) 2 inihi 4 inihi 6 inihi, kei reira te rauemi GaN e whakatipuria ana, mō te rama LED.
Ngā āhuatanga matua
1. Ngā āhuatanga hanganga:
He tauira koeko raupapa, he tauira koeko tapatoru rānei tō te mata PSS, ā, ka taea te whakahaere i tōna āhua, tōna rahi me tōna tohatoha mā te whakarerekē i ngā tawhā o te tukanga whakairo.
Ka āwhina ēnei hanganga whakairoiro ki te whakarerekē i te ara horapa o te mārama, me te whakaiti i te whakaata katoa o te mārama, ā, ka whakapai ake i te whai huatanga o te tango mārama.
2. Ngā āhuatanga o te rauemi:
Ka whakamahia e te PSS te hapaira kounga teitei hei rauemi papa, he āhuatanga o te pakeke teitei, te kawe wera teitei, te pumau matū pai me te mārama whatu.
Mā ēnei āhuatanga ka taea e te PSS te tu atu ki ngā taiao uaua pērā i te pāmahana me te pēhanga teitei, me te pupuri tonu i te mahi whatu tino pai.
3. Mahi whatu:
Mā te whakarerekē i te marara maha i te atanga i waenga i te GaN me te papa hapaira, ka whai wāhi te PSS ki ngā photon e whakaata katoa ana i roto i te paparanga GaN kia mawhiti atu i te papa hapaira.
Ka whakapai ake tēnei āhuatanga i te pai o te tango māramatanga o te LED, ā, ka whakanui ake hoki i te kaha o te kanapa o te LED.
4. Ngā āhuatanga o te tukanga:
He tino uaua te tukanga hanga o te PSS, he maha ngā mahi e whai wāhi ana pēnei i te tuhi kohatu me te whakairo, ā, me whai taputapu tino tika me te whakahaere tukanga.
Heoi, nā te whanaketanga tonu o te hangarau me te whakaiti i ngā utu, ka āta whakapaitia, ka āta whakapaitia hoki te tukanga hanga o te PSS.
Painga matua
1. Whakapai ake i te pai o te tango mārama: Ka whakapai ake te PSS i te pai o te tango mārama o te LED mā te whakarerekē i te ara horapa o te mārama me te whakaiti i te whakaata katoa.
2. Whakaroa i te ora o te rama LED: Ka taea e te PSS te whakaiti i te kiato o te nekehanga o ngā rauemi epitaxial GaN, ka whakaiti i te whakakotahitanga kore-ira me te au turuturu whakamuri i te rohe hohe, ka whakaroa i te ora o te rama LED.
3. Whakapai ake i te kanapa o te rama LED: Nā te whakapai ake i te pai o te tango rama me te roa o te ora o te rama LED, kua tino whakanuia te kaha o te rama LED i runga i te PSS.
4. Whakaitihia ngā utu whakaputa: Ahakoa he uaua te tukanga hanga o te PSS, ka taea e ia te whakapai ake i te whai huatanga o te kanapa me te roa o te ora o te rama LED, kia whakaitihia ai ngā utu whakaputa ki tētahi taumata, kia pai ake ai hoki te whakataetae o te hua.
Ngā wāhi tono matua
1. Rama LED: Mā te whakamahi i te PSS hei rauemi papa mō ngā maramara LED, ka taea te whakapai ake i te whai huatanga o te kanapa me te roa o te ora o te rama LED.
I roto i te mara o te rama LED, e whakamahia whānuitia ana te PSS i roto i ngā hua rama maha, pērā i ngā rama tiriti, ngā rama tēpu, ngā rama motuka me ētahi atu.
2. Ngā taputapu hiko-haurua: Haunga ngā rama LED, ka taea hoki te whakamahi i te PSS ki te hanga i ētahi atu taputapu hiko-haurua, pērā i ngā pūoko rama, ngā taiaho, me ētahi atu. He whānuitia ngā whakamahinga o ēnei taputapu i roto i te whakawhitiwhiti kōrero, te hauora, te hōia me ētahi atu mara.
3. Whakaurunga hikohiko: Nā ngā āhuatanga whatu me te pumau o te PSS, koinei tētahi o ngā rauemi tino pai i roto i te mara o te whakauru hikohiko. I roto i te whakauru hikohiko, ka taea te whakamahi i te PSS ki te hanga arataki ngaru whatu, pana whatu me ētahi atu wāhanga hei whakatutuki i te tuku me te tukatuka i ngā tohu whatu.
