Порівняння світлодіодних чіпів COB і SMD
What is COB(Chip On Board)? COB light source means that the chip is directly bonded and packaged on the entire substrate. That is, N chips are integrated on the inner substrate for packaging, and the LED chip is directly attached to the mirror metal substrate or ceramic substrate with high reflectivity. COB technology is mostly used in low-power chips are difficult to produce high-wattage LED lights. By dispersing the heat
