Hello Professionals,
To my best knowledge, heating is the #1 enemy for LED technology.
Having said that, COB should generate more heat due to the fact that multiple "chips" are packed closer compared to SMD.
If heat management is left out of this equation, COB should have a shorter lifespan and prone to other premature failures.
So how are COB better than SMD in terms of stability and lifetime?
In my case of LED street light, COB type would definitely under perform and create many issues without properly designed modules and heat sink. (IMO)
Any advantages to bypass SMD and adopt COB?
Would really appreciate your expertise on this topic!
