Background of 9mm Bi-color LED

The 9mm bi-color LED, as the name suggests, is an LED with two different colors, typically red and green, integrated into a single package with a diameter of 9mm. It is widely used in various fields such as automotive lighting, indicator lights, and decorative lighting. The development of 9mm bi-color LED technology is closely related to the advancement of LED packaging technology and the continuous optimization of LED materials.

Technology of 9mm Bi-color LED

The 9mm bi-color LED is based on the principle of LED packaging technology, which involves encapsulating the LED chip with a transparent or translucent material to protect it from external factors and enhance its luminous efficiency. The key to achieving bi-color in a single package lies in the use of two different LED chips, one for red and the other for green, which are then combined to form a single bi-color LED package. The packaging process of 9mm bi-color LED includes the following steps: 1. Chip selection: Select high-quality red and green LED chips with high luminous efficiency and stable performance. 2. Chip bonding: Bond the red and green LED chips to the lead frame using a bonding wire or adhesive. 3. Encapsulation: Encapsulate the bonded chips with a transparent or translucent material to protect them and enhance their luminous efficiency. 4. Soldering: Solder the encapsulated package to the circuit board using a reflow soldering process.
