Product Details

COB is an acronym meaning chip on board . It describes the technology behind the COB lights, referring to the packed LED chips mounted in direct contact with silicon carbide or sapphire substrate. The COB technology provides a high density of LEDs on a small surface (e.g., there are 342 LEDs on a 10mm x 10mm surface).

Typical Characteristics Curves

But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes

COB LED Screen packaging technology has great advantages compared with SMD packaging technology. Its pros: smaller space of LED beads, better protection performance, long service life, and low dead light rate. Its cons: difficulty in manufacturing finished products, maintenance inconvenience
