Through hole LED, also known as through hole light emitting diode, is a type of LED that features a traditional leaded package. This design allows the LED to be mounted on a printed circuit board (PCB) using through hole technology, which involves inserting the leads of the component through holes in the PCB and soldering them in place. Through hole LEDs have been widely used in various applications due to their reliability, cost-effectiveness, and ease of assembly. This article provides an in-depth introduction to the through hole LED industry, covering its history, applications, market trends, and future prospects.

History of Through Hole LED

The concept of the through hole LED dates back to the early days of LED technology. In the 1960s, when LEDs were first developed, they were primarily used for indicator purposes in calculators and other electronic devices. The early LEDs were typically through hole packages, as they were easier to mount and required less complex assembly processes compared to surface mount technology (SMT) components.

As LED technology advanced, through hole LEDs continued to be a popular choice for various applications, including automotive indicators, appliances, and decorative lighting. The development of high-brightness LEDs (HB-LEDs) in the late 1990s and early 2000s further expanded the applications of through hole LEDs, making them suitable for outdoor lighting and large-area displays.

Applications of Through Hole LED

Through hole LEDs are used in a wide range of applications across different industries. Some of the most common applications include:
