The Difference between SMD and COB Light Sources?

SMD and COB belong to SMD led. The shape of SMD and COB is not very different. What is the difference between SMD and COB?

Introduction of SMD and COB light sources

SMD LED light source is a single patch LED bead, which is directly mounted on the surface of the light-emitting diode. Compared with the direct-inserted light-emitting diode, the production efficiency is higher.

COB light source is the upgrade of SMD light source. COB (integrated) packaging technology directly encapsulates chips on board, that is, N chips are inherited and integrated on the inner substrate for encapsulation. High-power LED lamps are manufactured by using small power chips to disperse chips for heat dissipation, improve light efficiency, and improve the glare effect of the LED lamps, so that they emit a uniform surface.

What is the difference between cob and SMD led?

In general, cob packaging efficiency is higher than SMD, and its luminescence is more uniform. When choosing and purchasing led, we should pay attention to the difference between cob and SMD LED and choose according to our actual needs.
