Through hole LED, also known as through hole light emitting diode, is a type of LED with a lead structure that extends through the PCB (Printed Circuit Board) hole. This kind of LED has been widely used in various industries due to its simple structure, stable performance, and low cost. 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 has a long history. In the early days of LED development, through hole LED was the mainstream product. It was first invented in the 1960s, and its structure is relatively simple. The LED chip is mounted on the lead frame, and the lead frame is then inserted into the PCB hole. With the continuous development of LED technology, surface mount technology (SMT) gradually replaced through hole technology, but through hole LED still has a certain market share due to its advantages.

Types of Through Hole LED

Through hole LED can be divided into several types according to different parameters: 1. According to the light color, it can be divided into red, green, blue, yellow, white, and other colors. 2. According to the luminous intensity, it can be divided into high brightness, medium brightness, and low brightness. 3. According to the size, it can be divided into 0603, 0805, 1206, and other sizes. 4. According to the package material, it can be divided into ceramic package, plastic package, and metal package.

Applications of Through Hole LED

Through hole LED has a wide range of applications due to its stable performance and low cost. The main applications include: 1. Indicator lights: Through hole LED is widely used in various indicator lights, such as computer keyboard indicator lights, mobile phone indicator lights, and other electronic products. 2. Display screens: Through hole LED can be used for small-scale display screens, such as digital clocks, meters, and other instruments. 3. Advertising lights: Through hole LED can be used for various advertising lights, such as neon signs, LED billboards, and other advertising equipment. 4.
