Through hole LED, also known as through hole light emitting diode, is a type of LED that is mounted on a printed circuit board (PCB) using through hole technology. This technology has been widely used in various industries due to its advantages such as high brightness, low power consumption, and long lifespan. In this article, we will introduce the Through hole LED industry, including its history, types, applications, and future development trends.

History of Through Hole LED

Through hole LED technology was born in the late 1960s. At that time, due to the limitations of chip technology, through hole LED was the mainstream product in the LED market. With the development of chip technology, surface mount technology (SMT) gradually replaced through hole technology. However, due to the advantages of through hole LED in some applications, it has been continuously developed and has become an important part of the LED industry.

Types of Through Hole LED

Through hole LED can be divided into several types according to different parameters and structures: 1. Color: Through hole LED can be divided into red, green, blue, yellow, white, and other colors. The color of the LED is determined by the semiconductor material and doping element. 2. Size: Through hole LED can be divided into small, medium, and large sizes according to the diameter of the LED. The size of the LED affects its brightness and heat dissipation. 3. Structure: Through hole LED can be divided into single chip, dual chip, and multi-chip according to the number of chips. The structure of the LED affects its brightness and luminous angle.
