Through hole bi color LEDs, also known as through hole dual-color LEDs, are a type of light-emitting diode that can emit two different colors of light. They are widely used in various fields such as indicator lights, automotive lighting, and decorative lighting. In this article, we will introduce the industry of through hole bi color LEDs, including their characteristics, applications, market trends, and future development prospects.

Characteristics of Through Hole Bi Color LEDs

Through hole bi color LEDs have the following characteristics: 1. Structure: Through hole bi color LEDs have a through hole structure, which means the LED chip is mounted on the top of the LED package, and the pins are inserted into the through hole. This structure makes it easy to mount and solder the LEDs on the circuit board. 2. Color: Through hole bi color LEDs can emit two different colors of light, such as red and green, red and blue, or red and yellow. The color can be changed by using different color chips or by controlling the current through the LED. 3. Lighting Angle: The lighting angle of through hole bi color LEDs is usually 120 degrees, which ensures that the light is evenly distributed in all directions. 4. Wavelength: The wavelength of the light emitted by through hole bi color LEDs is usually between 620 nm and 660 nm for red, 520 nm for green, and 450 nm for blue. 5. Brightness: The brightness of through hole bi color LEDs can be adjusted by controlling the current through the LED. The higher the current, the brighter the light.
