LED chip and light source in LED high bay

Normally, the LED source in LED high bay, have 2 different types: 

1. SMD LED source on Aluminium PCB Board

2. COB LED 


Let’s analysis the advantages and dis-advantages of the different type LED source.

SMD LED source on Aluminium/copper PCB Board


Main Advantage:

1. Contact surface to the heatsink is big,so the heat could transmit better than COB LED

2. Could use different brand LED chips

3. More easy to control the lumen efficiency

4. Will have less failure rate than the COB LEDs

5. For factories,will spend less to repair a failure product

 

Disadvantage of the SMD LED light source:

1. More complicated production to producer of high bay

2. Light produced would not be so centrol

 

For the COB Light source

Advantages:

1. Easy and quick for production

2. Light would be centrol

 

Dis-advantages:

1. Heat too centrol

2. Contact surface too small

So,we could see,the SMD LED source would be better than the COB light source,as the cooling will be better,and much easier to guarantee the LED life.
