Yazi iinkcukacha ezithe vetshe malunga ne-COB kunye ne-CSP strip

COB strip ukukhanya sele emarikeni ukususela ngo-2019 kwaye imveliso entsha kakhulu eshushu, kananjalo CSP strips.Kodwa uyazi ukuba yintoni na iimpawu nganye?Abanye abantu kwakhona CSP strip njengoko COB ukukhanya strip, kuba inkangeleko yabo iyafana kakhulu kodwa eneneni ezahlukeneyo imicu ukukhanya, apha siza kuchaza umahluko ngokucacileyo.

COB strip ukukhanyaUlwakhiwo:

1> Flip chip. Ukutshintsha kombala kufezekiswa ngokufaka iphosphor.

I-2> I-chip enikezelwa ngumthengisi ayinayo i-fluorescent powder, ngoko ke i-factory kufuneka isebenzise i-fluorescent powder glue ukufezekisa umbala ofunekayo ngexesha lokuvelisa. Iindleko zeChip xa zithelekiswa neCSP ziya kuba sezantsi. Iimveliso ezimhlophe zifuna kuphela ukukhomba umbala we-phosphor glue, ukusebenza kakuhle kwemveliso, ixabiso elihambelanayo liphantsi. Le mveliso ayifanelekanga kwimveliso ye-RGB, ukuba wenza i-RGB, ufuna yonke inqaku lombala we-phosphors glue, kwaye emva koko kunye ne-point phosphors glue, ukusebenza okuphantsi kakhulu, ixabiso eliphezulu kakhulu lokuvelisa, ngoko ke i-COB ifanelekile ukukhanya okumhlophe, i-RGB, i-RGBW ephantsi, ixabiso eliphezulu, umbala okhanyayo awufani.

CSP strip ukukhanyaUlwakhiwo:

I-1> Flip chip, umthengisi sele eyalele i-fluorescent glue chip, i-factory ayifuni ukukhomba i-phosphor glue.
Ngenxa yokuba umthengisi wetshiphu yeCSP eza kwenza ukupakishwa kombala, ixabiso leCSP libiza kakhulu kunelo letshiphu yeCOB. Ukuba ukukhanya okumhlophe kwenziwe, ixabiso le-CSP liphezulu kune-COB ngoku. Ukuba kuya kwenza i-RGB, i-RGBW, ngenxa yokuba izinto ezifunyenweyo sele zilungile iglue chip, umenzi ufuna kuphela i-glue ye-welding chip, ayisekho ukucwangciswa kombala, ngoko ke ixabiso le-CSP RGB egqityiweyo, i-RGBW inenzuzo yokuthelekisa.

Umtya we-COB ukhanyisa nge-120 degree ngelixa umtya we-CSP unamacala ama-5 wokukhanya, omabini anendawo yokukhanya ebalaseleyo kunye nokukhanya okusebenzayo.Qhagamshelana nathikwaye singabelana ngolwazi oluninzi malunga nezibane ze-LED strip.
