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 applications, such as indicator lights, display screens, and decorative lighting. In this article, we will introduce the industry of through hole bi-color LEDs, including their types, applications, market trends, and future development prospects.

Types of Through Hole Bi-color LEDs

Through hole bi-color LEDs can be divided into two main types: common anode and common cathode. In a common anode through hole bi-color LED, the two colors are emitted from the same cathode, while in a common cathode through hole bi-color LED, the two colors are emitted from the same anode. 1. Common Anode Through Hole Bi-color LEDs In a common anode through hole bi-color LED, the two colors are emitted from the same cathode. The cathode is connected to the anode of the first color LED, and the anode of the second color LED is connected to the circuit. When the LED is powered on, the first color LED emits light, and when the second color LED is powered on, the second color LED emits light. 2. Common Cathode Through Hole Bi-color LEDs In a common cathode through hole bi-color LED, the two colors are emitted from the same anode. The anode is connected to the cathode of the first color LED, and the cathode of the second color LED is connected to the circuit. When the LED is powered on, the first color LED emits light, and when the second color LED is powered on, the second color LED emits light.

Applications of Through Hole Bi-color LEDs

Through hole bi-color LEDs have a wide range of applications in various fields due to their excellent performance and low cost. The following are some typical applications: 1. Indicator Lights Through hole bi-color LEDs are commonly used as indicator lights in electronic products, such as computers, mobile phones, and household appliances. They can display different colors to indicate the working status or error information of the equipment. 2. Display Screens Through hole bi-color LEDs can be used to create simple display screens, such as digital clocks, scoreboards, and information displays. They can display numbers, letters, and symbols in two colors, which is more eye-catching and informative. 3. Decorative Lighting Through hole bi-color LEDs are also used in decorative lighting, such as stage lighting, architectural lighting, and landscape lighting. They can create a colorful and dynamic atmosphere, enhancing the aesthetic effect of the environment. 4. Automotive Lighting Through hole bi-color LEDs are used in automotive lighting, such as turn signal lights, brake lights, and reverse lights. They can provide clear and reliable signals, ensuring driving safety. 5. Medical Equipment Through hole bi-color LEDs are used in medical equipment, such as patient monitors, medical instruments, and medical equipment indicators. They can display various information in two colors, facilitating medical operations and patient care.
