Through hole LED (Light Emitting Diode) is a type of LED that is mounted on a printed circuit board (PCB) using through hole technology. It has been widely used in various applications, such as indicator lights, display modules, and decorative lighting. In this article, we will introduce the through hole LED industry, including its history, types, applications, market trends, and future development prospects.

History of Through Hole LED

Through hole LED technology has a long history, dating back to the early 1960s. At that time, LED technology was still in its infancy, and through hole LED was the most common type of LED used in various applications. As the technology developed, surface mount technology (SMT) emerged, which gradually replaced through hole LED technology in many applications. However, due to its unique advantages, through hole LED technology has maintained a certain market share and continues to be widely used in various fields.

Types of Through Hole LED

Through hole LED can be divided into several types according to their shape, color, and light emitting characteristics. 1. Shape: Through hole LED can be divided into round, square, and other special-shaped types. The round type is the most common, followed by the square type. Special-shaped through hole LED is mainly used in decorative lighting and other special applications. 2. Color: Through hole LED can be divided into red, green, blue, yellow, and other colors. The color of the LED is determined by the material composition of the LED chip. Different colors of through hole LED are used in different applications to achieve different decorative effects. 3. Light Emitting Characteristics: Through hole LED can be divided into normal light, high brightness, and super brightness types. The brightness of the LED is determined by the size of the LED chip and the driving current. High brightness and super brightness through hole LED are mainly used in display modules and other applications that require high brightness.
