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

Isibane se-COB strip besikwimarike ukusukela ngo-2019 kwaye sisixhobo esitsha esishushu kakhulu, sikwayi-CSP strips. Kodwa uyazi ukuba zeziphi iimpawu zaso ngasinye? Abanye abantu babiza i-CSP strip ngokuthi yi-COB light strip, kuba inkangeleko yazo ifana kakhulu kodwa eneneni zii-light strips ezahlukeneyo, apha siza kuchaza umahluko ngokucacileyo.

Isibane se-COB stripUlwakhiwo:

1> Flip chip. Utshintsho lombala lufumaneka ngokusebenzisa i-phosphor.

2> Itshiphusi enikezelwa ngumthengisi ayinayo ipowder ekhanyayo, ngoko ke umzi-mveliso kufuneka usebenzise iglue yepowder ekhanyayo ukuze kufezekiswe umbala ofunekayo ngexesha lokuveliswa. Ixabiso letshiphusi xa lithelekiswa ne-CSP liya kuba liphantsi. Iimveliso ezimhlophe zifuna kuphela umbala weglue ye-phosphor, ukusebenza kakuhle kwemveliso, ixabiso elihambelanayo liphantsi. Le mveliso ayifanelekanga kwiimveliso ze-RGB, ukuba wenza i-RGB, udinga iglue ye-phosphor yenqaku ngalinye lombala, uze emva koko udibanise iglue ye-phosphor, ukusebenza kakuhle okuphantsi kakhulu, iindleko eziphezulu kakhulu zemveliso, ngoko ke i-COB ifanelekile ukukhanya okumhlophe, i-RGB, i-RGBW ukusebenza kakuhle okuphantsi, ixabiso eliphezulu, umbala okhanyayo awufani.

Isibane se-CSP stripUlwakhiwo:

1> Flip chip, umthengisi sele eodole i-fluorescent glue chip, umzi-mveliso awudingi ukukhomba i-phosphor glue.
Ngenxa yokuba umthengisi weetshiphusi ze-CSP uza kuqhuba inkqubo yokupakisha imibala, ixabiso le-CSP libiza kakhulu kunele-chip ye-COB. Ukuba kwenziwe ukukhanya okumhlophe, ixabiso le-CSP liphezulu kunele-COB okwangoku. Ukuba kukwenza i-RGB, i-RGBW, kuba izinto ezifunyenweyo sele ziyitshiphusi yeglue elungileyo, umenzi kufuneka ancamathisele ngqo itshiphusi ye-welding, akusekho nqubo yombala, ngoko ke ixabiso le-CSP RGB egqityiweyo, i-RGBW inenzuzo yokuthelekisa.

I-COB strip inokukhanya okuzii-degrees ezili-120 ngelixa i-CSP strip inokukhanya okuziicala ezi-5, zombini zinendawo yokukhanya egqwesileyo kunye nokusebenza kakuhle kokukhanya. Sinenguqulelo yokusetyenziswa ngaphakathi nangaphandle, uthotho oluncinci kakhulu luyafumaneka ukuba uyalufuna.Qhagamshelana nathikwaye singabelana ngolwazi oluthe kratya malunga nezibane ze-LED strip.
