He aha te rerekētanga i waenganui i a Gob me COB?

I te ao hangarau LED, he maha ngā wā ka kōrerohia ngā kupu GOB me COB ina whakaarohia ana ngā kōwae LED mahi-teitei mō ngā momo tono. He mea nui ēnei hangarau takai LED e rua hei whakarite i te roa, te whai hua, me te kanapa o ngā rama LED. Heoi, ahakoa e pā ana a GOB me COB ki ngā tikanga whakairi maramara LED, he rerekē rawa te hanganga, ngā tono, me te mahi.

A. He aha te COB (Chip on Board)?Mata Arataki?

Ko te COB (Chip on Board) he hangarau e whakamahia ana hei whakapiri tika i ngā maramara LED maha ki runga i tētahi papa, kāore he takai tuku iho. I roto i tētahi COB LED noa, ka whakapirihia ngā maramara LED maha ki tētahi papa kotahi, ki tētahi papa rānei, e āhei ai te hoahoa kiato ake, kia whai hua ake hoki. Ka tukuna e ngā COB LED he putanga mārama teitei ki tētahi wāhi iti, ā, he otinga pai mō ngā tono rama mahi-teitei me ngā tono rama arumoni.

1. Hanganga me te Mātāpono Mahi:

I roto i te COB LED, ko ngā maramara LED takitahi ko:

- Whakamaua tika ki runga i te papa: Ka whakatakotoria ngā maramara LED ki runga i te turanga, he rauemi tēnei he pai te kawe wera, pērā i te konumohe, hei āwhina i te tohatoha wera.

- Hononga hiko: Ka honoa tika ngā maramara ki te papa, kia pai ai te rere o te iahiko me te tohatoha pūngao.

- Te whakahaere wera: He maha ngā wā ka whakamahia e ngā rama COB LED ngā PCB matua whakarewa (MCPCB), e āwhina ana ki te whakamarara wera me te whakarei ake i te roa me te whai huatanga o ngā rama.

He tino rongonui te hangarau COB i roto i ngā whakaaturanga arumoni, pērā i te pānuitanga o roto, te pānuitanga o waho, me te huihuinga, nā te mea ka taea te whakaputa i te kanapa teitei me te ōritetanga o te mārama.

(1) Teitei o te Whaihua o te Kanapa: Ka whakaputahia e ngā rama COB LED he kanapa teitei, ā, he tino pai te putanga o te mārama, e pai ai mō te whakamārama nui.

(2) Te Whakahaere Wera Pai Ake: Mā te whakairi tika i ngā maramara ki runga i ngā papa e kawe ana i te wera ka whakarite kia pai te horapa o te wera, ka whakaiti i te mōrearea o te wera nui, ā, ka whakapai ake i te roa o te ora o ngā rama LED.

(3) Hoahoa Kiato: He maha ngā maramara LED e piri tahi ana, ka hangaia he mātotoru mārama nui i roto i tētahi wāhi iti, he mea tino pai mō ngā tono e hiahia ana ki te mārama kaha, ōrite.

(4) Te Pakari me te Pono: He pakari ake ngā rama COB LED i ngā rama SMD takitahi, nā te mea he pakari te mau o ngā maramara, ā, he iti ake te tūponotanga ki te pakaru mai i ngā wiri me ngā ru.

3. Ngā ngoikoretanga o ngā rama COB LED:

(1) Te Utu Teitei Ake: Ko ngā rama COB LED he nui ake te utu nā te mea he matatau te tukanga hanga me ngā rauemi kounga teitei e whakamahia ana mō te whakahaere wera.

(2) Ngāwaritanga Iti: Ko ngā rama COB LED e whakamahia whānuitia ana i roto i ngā tono pakari (pērā i ngā whakatakotoranga rama pumau) ā, kāore i te ngāwari pērā i ngā rama SMD LED, ka taea te whakairi ki runga i ngā PCB ngāwari.

B. He aha te GOB (Kāpia i runga i te Papa)?

Ko te GOB (Glue on Board) he hangarau tākai LED hou e whakarei ake ana i te hangarau COB tuku iho mā te whakamahi i tētahi paninga tiaki tāpiri, i tētahi kāpia rānei ki runga i te maramara LED, e whakapai ake ana i te roa me te pono o te LED. Kua hangaia te GOB hei ārai i te kino o ngā maramara LED mai i ngā āhuatanga o waho pēnei i te puehu, te makuku, me ngā wiri.

I roto i te whakatakotoranga GOB, i muri i te whakairinga o ngā maramara LED ki runga i te PCB (pērā i te whakatakotoranga COB), ka pania he paparanga tiaki o te kāpia epoxy, silicon rānei ki te mata. Ko te mahi a tēnei paparanga ko:

- Tiakina ngā maramara LED mai i ngā kino o te taiao (puehu, makuku, waikura).

- Whakapai ake i te putanga me te whai huatanga o te mārama mā te whakaiti i te mimiti o te mārama ka puta pea i roto i ngā wāhi e kitea nuitia ana.

- Whakarei ake i te pono mā te whakarite kia mau tonu ngā maramara LED ki tōna tūranga, kia mahi tonu hoki mō ngā wā roa, ahakoa i raro i ngā āhuatanga kino.

Ka āwhina anō hoki te kāpia e whakamahia ana i roto i te hangarau GOB ki te ōritetanga o te mārama me te ōritetanga o te tae, he mea nui ēnei i roto i ngā mahi pēnei i te Ngā Whakaaturanga Arataki me ngā tohu nui.

1. Hanganga me te Mātāpono Mahi:

- Ka whakamauhia ngā maramara LED ki runga i tētahi papa (pēnei i te PCB) pērā i te whakatakotoranga COB paerewa.

- Ka pania he kāpia, he epoxy rānei ki runga i ngā maramara hei tiaki me te hiri i a rātou, hei whakarei ake i te mahi a te kōwae.

- He pai ake te tiaki i te taiao: Ka hangaia e te kāpia he ārai e ārai ana i te makuku, te puehu, me ētahi atu poke ka whakaiti i te mahi a te maramara i roto i te wā.

He mea whakamahi whānuitia te GOB i roto i ngā tono tohu pānuitanga o waho me ngā taiao e pāngia ai ngā rama LED e ngā āhuatanga o waho, pērā i ngā whakaaturanga o waho, ngā rama tiriti, me ngā pūnaha rama ahumahi tino pakari.

2. Ngā Painga o ngā LED GOB:

(1) Te Pakari o te Manawanui: Mā te paparanga piri tiaki ka pai ake te tiaki i ngā maramara LED mai i ngā tūponotanga taiao, ka pai ai ngā LED GOB mō ngā mahi o waho me ngā mahi ahumahi.

(2) Te Tohatoha Mārama Pai Ake: Ka āwhina te kāpia ki te whakapai ake i te horapa o te mārama me te whakaiti i te āhua o ngā ira pōuri, te putanga mārama koretake rānei, kia ōrite ai te mārama.

(3) Ātete ki te makuku me te puehu: Mā te hangarau GOB ka piki ake te ātete o te LED ki te makuku, te puehu, me ētahi atu poke, ka roa ake tōna roa me te whakapai ake i te mahi i roto i ngā taiao uaua.

(4) Te Whakapai Ake i te Pono: Mā te whakau i ngā maramara LED ki te paparanga tiaki, ka iti ake te tūponotanga o ngā LED GOB kia pakaru i ngā kaha ā-tinana o waho, pērā i te wiri, i te ru rānei.

3. Ngā ngoikoretanga o ngā rama LED GOB:

(1) Te Utu Teitei Ake: He rite ki ngā LED COB, he nui ake te utu o ngā LED GOB nā ngā mahi hanga me ngā rauemi tāpiri i whakamahia i roto i te tukanga.

(2) Ngāwari Ngāwari: Pērā i ngā LED COB, ka whakamahia ngā LED GOB i roto i ngā whakaurunga pakari, ā, kāore pea e tino urutau ki ngā tono ngāwari.

(3) Te Ngaronga Tirohanga Pea: I ētahi wā ka taea e te paparanga piri te whakaiti i te mahi tirohanga, nā te mea ka mimiti pea i te mārama, ahakoa he iti noa iho tēnei pānga ina whakaritea ki ngā painga.
