Ob leeg COB thiab SMD LEDs muaj kev ua haujlwm siab luminous thiab ua haujlwm siab. Ob leeg muaj qhov ua tsis tau zoo heev.
COB LEDs tau siv ntau thiab ntau dua hauv kev siv teeb pom kev zoo nrog lawv cov qauv yooj yim, qis dua lub teeb poob thiab cov zis lumen siab hauv thaj chaw me me.
CREE, Seoul Semiconductor, Citizen, Bridgelux thiab Evercore yog cov ua lag luam COB LED hauv ntiaj teb. Cov neeg tsim khoom xws li Nichia, Osram, Lumileds, LG Innotek thiab Edison kuj sawv tawm hauv SMD LED thev naus laus zis.
Ob leeg SMD thiab COB thev naus laus zis muaj ntau qhov chaw thov. Ib qho ntawm ob lub thev naus laus zis yuav tsum raug xaiv raws li daim ntawv thov xav tau.
