Through hole LED (Light Emitting Diode) is a type of LED that uses a lead frame for mounting and a through hole for electrical connection. As a traditional LED technology, it has been widely used in various applications, such as indicator lamps, indicator lights, and decorative lighting. This article will introduce the industry of through hole LED, covering its history, types, applications, and market trends.

History of Through Hole LED

The history of through hole LED dates back to the 1960s when the first LED was invented. Initially, through hole LED was the mainstream technology for LED production. With the continuous development of LED technology, surface mount technology (SMT) gradually emerged and became the mainstream in the 1980s and 1990s. However, due to the advantages of through hole LED in certain applications, it still occupies a certain market share in the industry.

Types of Through Hole LED

Through hole LED can be divided into several types according to its structure and application. The following are the common types: 1. Round through hole LED: This type of LED has a round lead frame and is commonly used in indicator lamps and indicator lights. 2. Square through hole LED: With a square lead frame, this type of LED is often used in industrial applications, such as display screens and LED modules. 3. Aluminum through hole LED: This type of LED is made of aluminum, which has good heat dissipation performance. It is commonly used in high-power LED applications. 4. Transparent through hole LED: With a transparent lens, this type of LED can emit light in all directions, making it suitable for decorative lighting applications.
