LED 3mm bicolor is a popular type of LED lighting with a diameter of 3mm, which can emit two different colors simultaneously. It is widely used in various fields such as household appliances, automotive lighting, and decorative lighting. In this article, we will introduce the industry of LED 3mm bicolor, including its production process, market status, and future development trends.

Production Process of LED 3mm Bicolor

The production process of LED 3mm bicolor involves several steps, including chip preparation, encapsulation, and testing. The following is a detailed introduction to each step:

1. Chip Preparation

The first step in the production of LED 3mm bicolor is chip preparation. The chip is typically made of gallium nitride (GaN) or silicon carbide (SiC) materials. The chip is grown by epitaxial method, which involves depositing a thin layer of material on a substrate to form a single crystal structure. After the epitaxial growth, the chip is then diced into small pieces, each with a diameter of about 3mm.

2. Encapsulation

After the chip preparation, the next step is encapsulation. The encapsulation process involves coating the chip with a transparent or translucent material to protect it from external factors such as moisture and dust. In the case of LED 3mm bicolor, the encapsulation material is usually a silicone rubber or epoxy resin. The encapsulation process can be divided into the following steps: - Cleaning: The chip and the encapsulation material are cleaned to remove any impurities. - Coating: The encapsulation material is applied to the chip using a spin-coating or dipping method. - Curing: The coated chip is then cured to harden the encapsulation material. - Cutting: The encapsulated chip is cut into the desired shape and size.

3. Testing

The final step in the production of LED 3mm bicolor is testing. The purpose of testing is to ensure that the LED meets the required specifications and quality standards. The testing process includes the following: - Current-voltage characteristic test: This test measures the LED's forward voltage and current characteristics. - Color and brightness test: This test checks the LED's color and brightness output. - Stability test: This test evaluates the LED's performance under different environmental conditions.
