Through hole LED, also known as through hole light emitting diode, is a type of LED that uses a through hole technology to mount the LED chip onto a printed circuit board (PCB). It has been widely used in various industries, including automotive, industrial, and consumer electronics. In this article, we will delve into the through hole LED industry, covering its history, technology, applications, and future trends.

History of Through Hole LED

The history of through hole LED dates back to the early 1960s when the first LED was invented. However, it was not until the late 1970s that through hole LED technology was developed. Initially, through hole LED was used in low-power applications such as indicator lights and displays. Over the years, with the advancement of technology, through hole LED has evolved into a versatile and high-performance lighting solution.

Technology of Through Hole LED

Through hole LED technology involves mounting an LED chip onto a PCB using a through hole process. The LED chip is first mounted onto a lead frame, which is then inserted into a through hole on the PCB. The leads of the LED chip are then bent and soldered to the appropriate pads on the PCB. This process allows for a high degree of precision and reliability in the assembly of the LED.

One of the key advantages of through hole LED technology is its ability to provide a high level of thermal dissipation. The through hole design allows for better heat transfer from the LED chip to the PCB, which helps to maintain the LED's performance and lifespan. Additionally, through hole LED technology can accommodate larger LED chips, which results in higher brightness and better color rendering.
