what are differences between COB light source and LED light source

The principle is different

Cob light source: The high light efficiency integrated surface light source technology in which the LED chip is directly attached to the mirror metal substrate with high reflectivity.

LED light source: integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product.

Different advantages

Cob light source: It is convenient for the secondary optical matching of the product to improve the lighting quality; it is simple to install and easy to use, which reduces the difficulty of lamp design and saves the cost of lamp processing and subsequent maintenance.

LED light source: low heat, miniaturization, short response time, etc., all of which make the LED light source have great advantages and create favorable conditions for application in actual production and life.

the characteristics of the light source are different

Cob light source: high color rendering, uniform luminescence, no spot, healthy and environmentally friendly.

LED light source: It can be used continuously for up to 100,000 hours. In the future, LED light source applications will become mainstream in the field of lighting.
