More stable, fewer problems
1. COB strip is the chip directly attached to the FPCB, and does not come with gold wire. In Traditional SMD LED strips, very many problems are caused by the gold wire inside the LED beads. Because the gold wire is too small, it is straightforward to be broken, leading to the chip not being illuminated.
2. The circuit design of the COB strip uses three chips, first in parallel, as a group, then in each group, and then in series to form one step. Even if a group of two chips inside the bad, this one-step strip can continue to light. And COB a meter of chips how big 480, even if 1-2 chips do not light, will not produce dark areas, will not affect the use. While the traditional SMD strip, is a CUT, as long as there are lousy lamp beads, this one cut will not light, so there will be obvious to see a section of the dark area.
