What is COB LED Strip?

COB LED strip, or “Chips on Board LED Strip,” is a unique technology where LED chips are encapsulated directly onto a flexible PCB (Printed Circuit Board). This design linearly aligns flip-chips on the board, with a special encapsulation glue mixed with phosphor on the chip surface. The process results in diverse, uniform colors and color temperatures.

Often referred to as continuous or dotless LED strip lights, COB LED strips provide unparalleled brightness and color consistency. Their seamless light emission makes them a versatile and efficient choice for various lighting applications.
