Te uara Huna o tētahi LED e mau tonu ana

Ina hoko koe i tētahi rama LED, kei te hoko koe i ētahi atu mea i te whakamāramatanga anake; Kei te haumi koe i roto i ngā tau o te ratonga pono, pūngao māia. Ko te kī taurangi o te roanga o te oranga 50,000 haora tētahi o ngā take matua i kōwhiria ai e mātou te LED i runga i ngā hangarau tawhito ake. Heoi anō, ehara tēnei roa i te aituā. Ko te hua o te pūkaha uaua, ā, ko te mea nui, he rangatū o ngā hātepe whakahaere kounga uaua i mahia i mua noa atu i te taenga atu o te rama ki tētahi whata pātaka. I waenganui i ngā mea tino hira o ēnei hātepe ko te whakamātautau pakeke. Ahakoa he wā "tahu" ngāwari, ko te whakamātautau pakeke he tukanga mātanga, he tukanga matatini hoki i hoahoatia hei taru i ngā rahunga tūpono, hei manatoko i te mahinga wera, me te whakarite ka taea e ia mōtete, mai i te maramara LED ki te atekōkiri, te ātete i ngā uaua o te whakamahinga o te ao tūturu. Mō ngā kaiwhakanao pēnei i te OAK LED, ehara tēnei whakamātautau i te mahi taki pouaka; He tino whāinga ki te tuku i te kī taurangi kounga o te parani. Ka tūhura tēnei tuhipānui i te hiahiatanga o ngā whakamātautau pakeke, e whakamārama ana me pēhea te whakataruna i ngā tau whakamahi i roto i ngā haora, rā rānei hei whakaū i te tāutatanga o tētahi rama LED, kua rite ki te mahi i tōna pānga mōrahi i te wā tonu, i te pono hoki.

He aha te Whakamātautau Pakeke LED, he aha hoki i mahia ai?

Ko te whakamātautau pakeke LED, e mōhiotia ana hoki ko te whakamātautau tahu, he hātepe whakaū kounga e whakahaeretia ai ngā rama LED kua oti i raro i ngā here whakahaere, ā, i te nuinga o te wā ka whakaterea, mō tētahi wā roa i mua i te whakaaetanga mō te tukunga. Ko te whāinga matua ko te tāutu me te whakakore i ngā rahunga o mua—ko te wāhanga e kiia nei ko te "mate kōhungahunga" o te oranga o tētahi hua. Ka taea e ngā wae hiko, tae atu ki ngā LED me te atekōkiri, te whai hēnga tōmuri kāore i mau i te arotakenga arokite paerewa, i te whakamātautau taumahinga rānei. Kāore pea ēnei hēnga, pēnei i te hononga solder ngoikore, te wae hē rānei, te hē moroiti rānei i roto i tētahi maramara LED, i te wā o te whakamātautau poto e 5 meneti. Heoi anō, i muri i ētahi haora mahi, ka hinga ēnei pūwāhi ngoikore. Mā te whakahaere i ngā rama mō tētahi wā roa ake—i te nuinga o te wā e 24 ki te 48 hāora, neke atu rānei, ā, i ētahi wā tae atu ki te wiki mō ngā taupānga whaikiko tiketike—ka āki te whakamātautau pakeke i ēnei rahunga mate kōhungahunga kia puta i roto i te wheketere, i reira ka taea te whakatika, te whiu rānei i te wae hē, kaua ki te ringa o te kiritaki. He tātari whakamutunga, takenui e whakarite ana i ngā hua pakari, taumahinga-katoa anake ka tae ki te mākete, e tiaki ana i te rongo o te kaiwhakanao me te pūtea penapena a te kaiwhakamahi whakamutunga.

He pēhea te whakahaere i tētahi whakamātautau pakeke paerewa?

Kua āta whakapūtātia ngā here mō tētahi whakamātautau pakeke paerewa kia whakahaeretia me te māngai o te whakamahinga tūturu. I te nuinga o te wā, ka whakahaeretia te whakamātautau i roto i tētahi taiao me te kore whakahau i te hauora hāngai ki runga i ngā wae, kia taea ai e rātou te tae ki tō rātou pāmahana mahi tūturu, ā, i te pāmahana taiao pūmau, i te nuinga o te wā ka puritia i waenganui i te 20°C me te 30°C (68°F ki te 86°F). He tino nui tēnei pāmahana ā-taiao whakahaere mō te tukuruatanga me te whakarite kāore ngā hua whakamātautau e tītaha ana i ngā take taiao o waho. Ka whakatūria ngā rama ki tētahi huarahi e tāwhai ana i tā rātou tāutanga tika, e āhei ai te whakakore wera pūnoa mā ā rātou totohu wera i hoahoatia. Kātahi ka "whakakāngia noatia," ko te tikanga ka whakakāngia, ka whakahaeretia e ai ki ō rātou here kua whakaritea. Ko te mea nui, ka whakahikotia rātou i tō rātou ngaohiko whakatauranga ingoa, i ētahi take rānei, i te ngaohiko mōrahi o tō rātou awhe whakatauranga hei whakataruna i tētahi tauari kino rawa mō te putanga hiko. I roto i tēnei wā, ka taea e ngā tohutūmahi, ngā pūnaha aroturuki aunoa rānei te taki i ia wā mō te kōpiu, te whakarongo ki ngā haruru rerekē mai i te atekōkiri, me te manatoko kei te mau tonu te huaputa mārama. Mā tēnei tukanga pūnaha e whakarato te apa tuatahi o te whakaūnga e tutuki ana te taumahinga taketake me te kounga huihuinga o ia rama ki te paerewa e hiahiatia ana.

He pēhea te whakatau a te whakamātautau pakeke i te pāpātanga mate LED?

He rerekē te ariā o te "pāpātanga mate" i roto i ngā LED i ngā pūrama tūturu, engari ka taea e ngā rahunga te puta, i te tīmatanga o te oranga. I raro i te ngaohiko whakatauranga pūnoa me te onāianei, ko te kōwae LED kua huihuia paitia mai i tētahi kaiwhakanao rongonui me tino iti rawa te mokatere rahunga inamata. Heoi anō, ehara te ao tūturu i te "pūnoa" i ngā wā katoa. Ka pā ki ngā mātiti hiko ngā pātōtō, ngā tara, me ngā weto ohorere. I hoahoatia te whakamātautau pakeke hei whakataruna me te tūmanako i ēnei takahanga uaua. Hei whakarite ka taea e te rama te ātete i ēnei takanga noa, ko te tukanga pakeke he uaua ake ngā huānga i tua atu i te mahi haere tonu. Tērā pea ko te tuku i ngā rama ki ngā huringa hiko—kia tere te whakakā, ki te whakaweto rānei, i ngā wā tauwhāiti rānei—hei whakamātau i te manawanui o nāianei o te atekōkiri me te pakari o te pūnaha katoa. Ka taea hoki te whakahaere i ngā rama i ngā ngaohiko iti ake mō ngā wā poto hei whakamātau i ngā wae o te putanga hiko. Ko te whāinga ko te manatoko e tika ana te hanganga o te puna hiko, kua kaha te whakapiri i ngā tūnga welding katoa, ā, ka taea te whakahaere i te whakawhānui wera me te whakahekenga, ā, kua tae te mahi o te raina huihuinga katoa ki tētahi paerewa e āhei ana ki te ātete i ngā raruraru hiko o te ao tūturu. Ko te rama e puta ana i tēnei momo whakamātautau hau, he iti iho te hinga ina anga atu ki tētahi pana hiko, ki tētahi weto poto rānei i tōna tāutanga tūturu.

He aha te take i tino nui ai te whakamātautau hau wera mō te whakakore wera LED?

Tērā pea ko te take tino nui i roto i te roanga o te LED ko te whakakore wera tōtika. E ai ki ngā tuhinga o mua, ko te wera i hangaia i te komititanga LED, ki te kore e tika te whakahaere, ka tere te whakatere i te whakahekenga o te lumen, ā, ka rahunga wawe. He mahi nui te whakamātautau pakeke ki te manatoko i te hoahoa wera o te rama. Ahakoa ka mahia ngā whakataruna wera i te wā o te wāhanga hoahoa, ka homai e te whakamātautau pakeke he whakatika ā-ringa. I te wā o te whakamātautau, ka whakahaeretia tonutia te rama LED, e taea ai te tae ki tōna pāmahana tauritenga wera mōrahi. I te nuinga o te wā ka mahia tēnei i te pāmahana taiao teitei, i te kawenga whakatauranga mōrahi rānei hei pana i te pūnaha wera ki ōna tepe. Ka taea e ngā kaihangarau te whakamahi i ngā kāmera atahanga wera, i ngā thermocouples rānei hei ine i te pāmahana i ngā wāhi takenui: te tūtakinga LED (hāngai), te totohu wera, ngā wae atekōkiri, me te whare. Ko te paearu hipa / rahua matua, kāore te hanganga ā-roto me ngā wae e whakangaromia, e whakahekea rānei e tēnei hau wera roa, ā, ka whakatikatika te pāmahana o ia wāhanga, ā, kāore e piki haere tonu i roto i te wā. Ka tae te rama i hoahoatia paitia ki tētahi mānia pāmahana pūmau, e tohu ana kei te pai te whakaputa i te wera ki te taiao. Ki te piki haere tonu te pāmahana, ka tohu i tētahi rahunga whakahaere wera taketake, ko te tikanga ka tino poto ake te ora o te rama i te papa tākaro. Ko te whakamātautau pakeke te manatokonga whakamutunga, kāore e taea te whakakāhore e tika ana te rongoā whakamātao mō te mahi.

He pēhea te whakamātautau pakeke e whakarite ai i te tōtika mārama pūmau me te mahinga hiko?

Ko te tōtika mārama me te pūmautanga o tētahi rama LED i roto i tōna oranga e herea hāngai ana ki te kounga me te ōritetanga o tōna puna hiko ā-roto, atekōkiri rānei. Ko te mahi a te atekōkiri ko te tahuri i te hiko matua AC e tārere ana ki tētahi hiko DC pūmau, kua whakaritea mō ngā LED. Ko te take matua e pā ana ki te pūmautanga mārama mo te wā roa ko te kaha o te atekōkiri ki te pupuri i tēnei au taimau ahakoa ngā rerekētanga o te ngaohiko tāuru me te pāmahana. I te wā o te whakamātautau pakeketanga, ka whakaurua te pahekotanga o te atekōkiri me ngā kōwae LED i ōna tere. Ka aroturuki te whakamātautau mō ngā tohu tāpepe, pēnei i te kōpura kitea (tērā pea he tohu o tētahi huaputa kāore i te whakaritea), i te nekehanga āta haere rānei o te huaputa mārama. Ahakoa ehara te whakamātautau pakeke i te matapae LM-80/TM-21 katoa, he taki nui mō te mahinga hiko "i waho o te pouaka". Ka manatokona kei te mahi tika ngā ara iahiko me ngā ara iahiko ture, ā, kei te mahi ngā pūrere parenga ngaohiko nui ki te tikanga. Mēnā he hēnga māheahea i roto i ngā wae o te atekōkiri—pēnei i te pūkaha hē, i tētahi maramara mana tōkarikari kino rānei—ka puta i te wā o te whakamātautau tahuna maha hei rahunga, he kōpura kōpiu, he wera nui rānei. Mā te hopu wawe i ēnei take, ka whakapūmautia e te whakamātautau pakeke ka tukuna e te rama tōna tōtika mārama mai i te wā e tāutatia ana.

He aha te take i tino nui ai te whakamātautau kōpura o te tukanga pakeke?

Ko tētahi āhuatanga tauwhāiti, tino nui hoki o te whakamātautau koroheketanga ko te whakamātautau kōpuru. Ko te kōpiu, te tere rānei, ngā tārere auau o te huaputa mārama, ka kore e kitea e te whatu tahanga, ka tino mārama, ka pōrearea rānei. I takea mai i ngā hēnga o te iahiko huaputa o te atekōkiri, i te nuinga o te wā e pā ana ki te pārekareka mai i te wāhanga tahuringa AC-ki-DC. Ahakoa he kino ētahi kōpura auau tiketike, ka taea e te kōpura auau-iti te uaua o te whatu, te ānini, me ngā take haumaru i roto i ngā taiao mahi me ngā mīhini tītaka. I te wā o te whakamātautau pakeketanga, ka tirohia ia rama, ā, i te nuinga o te wā ka aroturukitia e ngā pūoko whakaahua, mō ngā tohu kōpura. E hiahiatia ana tēnei whakamātautau nā te mea ka puta mai ngā take kōpura i ngā manawanui mōtete motuhake, i ngā hapa whakaminenga rānei. Hei tauira, ka kitea pea tētahi hapa i te tukanga pōkai o te pūkaha rama LED, tētahi wae uara iti rānei i te wāhanga tātari o te atekōkiri i muri i te mahana o te rama, ā, ka haere mō tētahi wā. Ko te whakamātautau pakeke, mā te whakahaere i te rama mō tētahi roanga roa, ka whai wāhi ki te mātaki i ēnei take. Ko te whakarite i tētahi mahi kore-piu, pūmau, pūnoa hoki te hipanga whakamutunga ki te whakamana kei te mahi tika te wāhanga rama LED, tōna atekōkiri, me ngā tūhononga katoa hei tuku i tētahi wheako tīramarama tino kounga, pono hoki.

Ngā Whāinga Matua o ngā Whakamātautau Pakeke LED

Ko te ripanga e whai ake nei e whakarāpopoto ana i ngā whāinga matua me ngā tikanga o te tukanga whakamātautau pakeke LED.

I te mutunga, he nui ake te whakamātautau pakeke i te wā "whakahaere" ngāwari. He tukanga whakahaere kounga whānui, matatini e whakataruna ana i ngā uaua o te oranga tōmua kia tino pakari, pono, me te rite ki te tuku i tana kī taurangi o te whakamāramatanga roa, mahinga tiketike. Mō te kaihoko, e tohu ana i tētahi pūmautanga tē kitea, engari he tino nui te kounga. Mō tētahi kaiwhakanao pēnei i a OAK LED, he hipanga tino nui ki te hanga i te whakawhirinaki me te tautoko i tētahi rongo mō te tino pai i roto i tētahi mākete whakataetae o te ao. Ko te whakaūnga whakamutunga, tino nui ina tāuta koe i tētahi hua LED OAK, ka whakarato i te tīramarama mōrahi, mōrahi mō ngā tau e haere ake nei.

Ngā pātai auau mō ngā whakamātautau pakeke LED

Kia pēhea te roa o te whakamātautau pakeke LED noa?

Ka rerekē te roanga o te whakamātautau pakeke i runga anō i ngā paerewa kounga o te kaiwhakanao me te momo hua. Mō te nuinga o ngā rama LED arumoni, he mea noa iho te wā tahu o te 24 ki te 48 haora. Mō ngā taupānga nui ake, ngā hua taumata tiketike rānei, ka taea tēnei te whakaroa atu ki te 72 haora, 96 haora, ki te wiki katoa rānei hei whakarite i te taumata tiketike o te whaikiko me te taru i ngā rahunga o te oranga tōmua.

Ka whakapoto te whakamātautau pakeke i te oranga katoa o te LED?

Kāo, kāore te whakamātautau pakeke e whakahaere tika ana i te whakapoto i te oranga katoa o tētahi LED. Ko te 24 ki te 48 hāora o te mahi e tohu ana i tētahi hautanga iti o te roanga o te 50,000+ haora o te LED (iti iho i te 0.1%). I hoahoatia te whakamātautau hei tāutu i ngā wae tērā pea i rahua i te moata, me te pare i te kiritaki mai i te raruraru me te whakarite kia tukuna ngā hua tino pakari anake.

Ka taea e au te mahi i tētahi whakamātautau pakeke ki ngā LED kua tāuta kētia e au?

Ahakoa ka taea e koe te whakahaere tonu i ō rama, kāore e taea e koe te mahi i te momo whakamātautau koroheketanga i mahia i roto i tētahi wheketere. Ko ngā whakamātautau wheketere e pā ana ki ngā ngaohiko teitei, te huringa hiko tere, me te aroturuki wera pū kāore e taea i roto i tētahi tāutanga paerewa. Mō ngā rama kua tāutatia, ko te mahi pai rawa atu ko te mātakitaki noa iho mō ngā kōpura wawe, rahunga rānei i roto i ngā rā tuatahi o te whakamahinga, ka hipokina i raro i te pūtāhui.
