Detailed explanation of the advantages and disadvantages of each

What are the advantages of LED beads? Cob in LED lights. The appearance of LED light beads has experienced direct insertion and chip mounting. With technological progress, it is natural to present the highly integrated packaging of multiple LED light emitting chips directly on the substrate (integrated circuit and heat dissipation design), forming a compact, high-power, and ultra high-power LED light emitting component, which is called "COB" (seemingly a light bead, theoretically a group of light beads).

And what are the advantages of patches? Integrated LED is usually a nickname for COB light sources in the market, but theoretically, the characteristics of COB light sources cannot be clearly described. COB refers to Chip On Board, which packages low-power chips directly onto an aluminum substrate for rapid heat dissipation. The chip has a small area, high heat dissipation efficiency, and low driving current. Therefore, it has high heat dissipation with low thermal resistance and high thermal conductivity. Compared to ordinary SMD low-power light sources, it has higher brightness and lower thermal resistance
