LED packaging refers to the packaging of light-emitting chips. Generally speaking, the function of the package is to provide sufficient protection for the chip to prevent the chip from failure due to long-term exposure in the air or mechanical damage, so as to improve the stability of the chip. For LED packaging, it is also necessary to have good light extraction efficiency and good heat dissipation. A good package can make the LED have better luminous efficiency and heat dissipation environment, thereby improving the life of the LED.
