Through hole LED, also known as through hole light emitting diode, is a widely used type of light emitting diode in various industries. As the name suggests, the lead of this LED is inserted into the hole in the circuit board, which has the advantages of simple assembly, low cost, and wide application. In this article, we will introduce the development history, characteristics, applications, and market prospects of through hole LED in the industry.

Development History of Through Hole LED

The through hole LED was first developed in the 1960s. At that time, due to the limitations of technology, the production cost of surface mount devices (SMD) was relatively high, and the through hole LED was favored by the market. With the continuous development of technology, the cost of SMD has gradually decreased, and its advantages in miniaturization and high density have become more prominent. However, due to the wide application of through hole LED in the field of general lighting, its market share has not been significantly eroded.

Characteristics of Through Hole LED

Compared with SMD LED, through hole LED has the following characteristics:

• Simple assembly: Through hole LED can be directly inserted into the hole of the circuit board, which is more convenient for assembly and debugging.

• Low cost: The production process of through hole LED is relatively simple, which reduces the production cost.

• Good heat dissipation: Through hole LED has a larger contact area with the circuit board, which is more conducive to heat dissipation.

• Stronger stability: The lead of through hole LED is inserted into the hole of the circuit board, which is more stable than the SMD LED.

Applications of Through Hole LED

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

• General lighting: Through hole LED is widely used in various general lighting products, such as lamps, lanterns, and street lights.

• Display: Through hole LED can be used for display applications, such as LED screens, LED billboards, and LED digital clocks.

• Signal indication: Through hole LED can be used for signal indication applications, such as indicator lights, alarm lights, and traffic lights.

• Medical equipment: Through hole LED can be used in various medical equipment, such as endoscopes, surgical lamps, and X-ray machines.

Market Prospects of Through Hole LED

In recent years, with the continuous development of the LED industry, the market demand for through hole LED has been growing. According to market research, the global through hole LED market size is expected to reach US$XX billion by 2025. The main reasons for the market prospects of through hole LED are as follows:

• Technological innovation: With the continuous optimization of production technology, the quality and performance of through hole LED are constantly improving, which promotes the expansion of the market.

• Cost advantage: Compared with SMD LED, through hole LED has a certain cost advantage, which is more conducive to market expansion.
