Guangmai Technology is proffesional in making the LED COB 7W Chip Light Source White Color.
COB and MCOB comparison
The COB packaging of LEDs is based on the packaging foundation of the inner substrate, that is, N chips are inherited and integrated on the inner substrate for packaging. This is the COB technology that everyone calls. Everyone knows that the substrate of the inner substrate is copper foil. It can only be energized well, and can not do good optical processing. In terms of light efficiency and cost: COB is to encapsulate the LED chip into a whole inner substrate. Because the coating of the encapsulant and the phosphor is distributed in a plane, it is difficult for the phosphor at the edge to be excited. Use has caused a lot of waste.
MCOB technology encapsulates LED chips into optical cups, learns the essence of LED SMD device dispensing, and coats phosphors on each single chip and completes the dispensing process. Using this method, the amount of phosphors used will be greatly cut back. At the same time, the LED chip light is concentrated inside the chip, and the MCOB planar light source is a multi-cup integrated chip, which provides more light outlets, so that the light can be emitted from multiple angles, and the light efficiency is significantly improved.
