Ke ulu wikiwiki nei ka ʻoihana kukui ʻāwīwī LED, a ua ʻike ʻia nā kukui kukui COB LED. I kēia manawa aia kahi ʻenehana hou, CSP LED kaha. E nīnau paha ʻoe, he aha ka CSP LED strip? He aha nā pōmaikaʻi o nā kukui LED CSP? E pane au i kēia mau nīnau iā ʻoe ma kēia ʻatikala. No laila, e hoʻomaka kākou.
He aha ka CSP LED?
ʻO CSP, a i ʻole Chip Scale Package, e pili ana i kahi pūʻolo LED i like ka nui o kahi pahu LED, a ʻaʻole ʻoi aku ma mua o 20%. Hōʻike nā huahana CSP i nā ʻāpana i hoʻohui ʻia ʻaʻole koi i nā hoʻopili uea solder, e hopena i ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻuʻuku nā ala hoʻololi wela, a me nā wahi hiki ʻole.
Ua hoʻohana mua ʻia nā LED CSP i nā kukui pale kelepona paʻa a me nā kamepiula papa a ua hoʻomaikaʻi ʻia e ka ʻoihana a hoʻohana ʻia i nā ʻāpana kukui papa maʻalahi.
He aha ka CSP LED strip?
Nā ʻāpana LED CSP ua like ia me nā mea maʻamau, koe wale nō ka hoʻohana ʻia ʻana o nā LED CSP, i hoʻopili ʻia i kahi PCB maʻalahi, a uhi ʻia me ke kāpili fluorescent translucent.
He aha ka COB LED strip?
Kū ʻo COB no Chip on Board ma ke kahua LED, ʻo ia hoʻi, ua hoʻopili pololei ʻia ka chip LED ma ka papa kaapuni (PCB). ʻO nā LED "Chip on Board" no nā kukui ʻōniʻoniʻo hiki ke kapa ʻia he flip-chips.
ka COB alakai kaula Aia nā ʻāpana i hoʻopaʻa ʻia ma kahi papa hikiwawe. ʻO nā chips he flip-chips, kahi i hoʻopaʻa ʻia ma ka papa PCB, a laila hāʻule pololei kahi papa o ka encapsulation glue i hui pū ʻia me ka phosphor ma ka ʻili o ka chip. ʻO ke kukui i hoʻokuʻu ʻia mai ka chip ua refracted, hōʻike ʻia, a hui pū me ka phosphor, a hoʻopuka ka glue i nā kala like ʻole a me nā mahana kala o ka mālamalama.
No ka ʻike hou aku, e ʻoluʻolu e heluhelu i ka ʻO nā mea āpau e pono ai ʻoe e ʻike ma mua o ke kūʻai ʻana i ke kaula alakaʻi COB.
Hoʻohālikelike o ka CSP LED strip a me COB LED strip
Keʻano
He melemele ke kāpili o ka COB LED strip no ka mea ua hui ʻia ke kāpili me ka phosphor.
He keʻokeʻo keʻokeʻo keʻokeʻo ke keʻokeʻo o ka CSP LED strip, ʻaʻohe phosphor i hui pū ʻia i loko o ke kāpili.
Ka hoʻomanawanui kala
Nā ʻāpana LED CSP ʻoi aku ka maikaʻi o ka waihoʻoluʻu kala, ʻo ia ka mea maikaʻi loa i hoʻohālikelike ʻia i nā ʻāpana LED COB.
No ka mea he kukui kukui ka CSP LED, liʻiliʻi loa ka nui. Ma kēia ala, hiki i ka mīkini ke hoʻokaʻawale i ka CSP LED i BIN.
Hoʻopili pololei ʻia ka chip i ka PCB maʻalahi no nā ʻāpana LED COB, a laila uhi ʻia ka PCB me ke kāpili me ka pauka phosphor. Hoʻopuka ʻia ke kukui keʻokeʻo e ka puʻupuʻu kukui uliuli me ka phosphor. ʻAʻohe ala no ka COB LED strip BINNING ma o ka mīkini.
Hiki i nā ʻāpana LED CSP ke hoʻokō i 3-step Macadam color tolerance, aʻo COB LED strips hiki ke hoʻokō wale i 5-step Macadam color tolerance.
No ka ʻike hou aku ma LED BINNING, e ʻoluʻolu e nānā i ka wikiō ma lalo nei.
Ka hoʻokō pono kukui
ʻO nā kukui LED CSP e hele mai me ka ʻoi aku ka maikaʻi o ka luminous. No ka mea ua uhi ʻia ka ʻili o ka CSP LED me ka translucent milky white glue, ʻoi aku ka kiʻekiʻe o ka transmittance māmā.
Hoʻohui ʻia ke kāpili e uhi ana i ka chip me nā phosphors melemele no nā ʻāpana LED COB, no laila he haʻahaʻa ka haʻahaʻa.
Kaulike māmā
ʻOi aku ka maikaʻi o ka māmā māmā o ka COB LED strip.
ʻOi aku ka nui o nā ʻāpana LED COB ʻaʻole i loaʻa kahi hopena māmā me ka nui o nā LED like me nā ʻāpana LED CSP.
Panina
Nā ʻāpana LED CSP a loaʻa i nā ʻāpana COB LED ko lākou pono a me nā hemahema. Ma hope o ka heluhelu ʻana i kēia ʻatikala, manaʻoʻiʻo wau ua ʻike ʻoe pehea e koho ai ma waena o nā ʻāpana LED CSP a me nā ʻāpana LED COB. No ka ʻike kikoʻī hou aku e pili ana i ka CSP led strip, hiki iā ʻoe ke heluhelu ʻO ke alakaʻi hope loa i ka CSP LED Strip.
Hana ʻo LEDYi i ke ʻano kiʻekiʻe Nā kāʻei LED a me ka neon flex LED. Ke hele nei kā mākou huahana a pau ma nā hale hana ʻenehana kiʻekiʻe e hōʻoia i ka maikaʻi loa. Ma waho aʻe o kēia, hāʻawi mākou i nā koho maʻamau i kā mākou LED strips a me neon flex. No laila, no ke kāʻei LED premium a me ka neon flex LED, hoʻopili iā LEDYi ASAP!
