Through hole LED, also known as through hole light emitting diode, is a widely used lighting component in various industries. As a traditional LED technology, through hole LED has been playing a crucial role in the development of the lighting industry. This article will introduce the concept, development history, application fields, and market prospects of through hole LED in detail.

Concept and Classification of Through Hole LED

Through hole LED refers to the LED device with the lead wire directly inserted into the lead frame through the hole. It has the characteristics of simple structure, low cost, and good heat dissipation. According to the light emitting color, through hole LED can be divided into red, green, blue, yellow, white, and other types. According to the package form, it can be divided into round, square, and other shapes.

Development History of Through Hole LED

The development of through hole LED can be traced back to the 1960s. At that time, due to the limitations of technology, the LED package was mainly through hole type. With the continuous development of technology, through hole LED has undergone several generations of evolution. From the early black LED to the current high-brightness LED, through hole LED has always occupied a dominant position in the market.

Application Fields of Through Hole LED

Through hole LED has a wide range of application fields. The main application fields include: 1. Indicator lighting: Through hole LED is widely used in various indicator lights, such as computer keyboard, switch, and display screen. 2. Decorative lighting: Through hole LED is used for decorative lighting in home, office, and public places. 3. Industrial lighting: Through hole LED is used in industrial lighting, such as workshop, warehouse, and outdoor lighting. 4. Traffic lighting: Through hole LED is used in traffic signal, road sign, and other traffic lighting equipment. 5. Medical equipment: Through hole LED is used in medical equipment, such as endoscope, blood pressure meter, and other instruments.

Market Prospects of Through Hole LED

With the continuous development of the lighting industry, the market demand for through hole LED is increasing. The following factors contribute to the market prospects of through hole LED: 1.
