Revolutionizing Lighting Solutions: The Power of Through Hole LEDs

Through hole LED, also known as through hole light emitting diode, is a type of LED that is designed with a leadless structure. As one of the earliest forms of LED, through hole LED has been widely used in various industries due to its advantages such as easy installation, low cost, and high brightness. In this article, we will introduce the industry of through hole LED, including its history, classification, application fields, and future development trends.

History of Through Hole LED

Through hole LED was first developed in the 1960s, and it quickly gained popularity due to its low cost and easy installation. At that time, through hole LED was mainly used in indicator lamps and other low-power applications. With the continuous development of LED technology, through hole LED has gradually been replaced by surface mount LED (SMD LED) in many fields. However, due to its advantages, through hole LED is still widely used in some special applications.

Classification of Through Hole LED

Through hole LED can be classified according to different criteria. The following are some common classification methods:

1. According to the color of the LED, it can be divided into red, green, blue, yellow, white, and other colors.
2. According to the light emitting angle, it can be divided into 0°, 45°, 90°, and other types.
3. According to the material, it can be divided into gallium arsenide (GaAs), gallium phosphide (GaP), and other materials.
4. According to the package form, it can be divided into through hole LED, SMD LED, and other types.

Application Fields of Through Hole LED

Through hole LED has a wide range of application fields, mainly including the following:

1. Indicator lamps: Through hole LED is widely used in indicator lamps, such as computer keyboard indicators, power indicators, and other electronic products.
