Through-Hole LEDs: Benefits and Applications

The through hole LED, also known as TH LED, is mounted on a printed circuit board (PCB) using holes drilled into it. LEDs of this type are commonly used in electronic devices and circuit boards, and they offer a variety of benefits, making them a popular choice across many industries.

What is a Through Hole LED?

An LED mounted through a hole on a PCB is connected to the PCB via its leads, which are soldered to copper pads, providing a secure connection between the LED and the board.

Through hole LEDs come in different shapes and sizes, including round, square, and rectangular. They can also be designed to emit light in different directions, such as 90 degrees or 120 degrees, depending on the application. Through hole LEDs come in a variety of colors, including red, green, blue, and yellow.

Benefits of Through-Hole LED

Durability

Unlike other LEDs, through hole LEDs are designed to be durable, with strong leads that ensure a reliable connection to the PCB. This makes them ideal for applications that require high levels of vibration or shock resistance, such as automotive or aerospace.

Easy to replace

A through hole LED can easily be replaced if it becomes damaged or faulty. The leads can be easily disordered from the PCB and replaced with a new one.

Versatile

LEDs are versatile and can be used in many different applications, from simple indicator lights to more complex lighting systems. They can also be combined with other components on a PCB, such as resistors, capacitors, and transistors.

High Brightness

With through-hole LEDs, high levels of brightness can be achieved, making them ideal for outdoor signage or displays that require high levels of illumination.

Applications of Through-Hole LED

Indicator lights

Typically, through hole LEDs are used in indicator lights on electronic devices or appliances to indicate the status of the device or to provide visual feedback to the user.

Backlighting

For backlighting LCD screens, through hole LEDs provide a uniform and even illumination, making them an excellent choice for applications requiring high levels of brightness and uniformity.

Automotive lighting

A through-hole LED is commonly used in automotive lighting, such as taillights, turn signals, and dashboard indicators. Its durability and shock resistance make it an ideal vehicle component.

Outdoor signs and displays

Through-the-hole LED is commonly used in outdoor signs and displays, such as billboards and scoreboards. Its high brightness and durability make it an excellent choice for outdoor applications. Get more info about High Power LED.

Consumer electronics

Through-the-hole LED is commonly used in consumer electronics, such as televisions, laptops, and smartphones. It can be used for backlighting displays or for indicator lights.

In conclusion

It has a wide range of benefits, including durability, ease of replacement, versatility, and high brightness. It is commonly used in electronic devices and circuit boards. Indicator lights, backlighting, automotive lighting, outdoor signs and displays, and consumer electronics are among the applications where through hole LEDs are commonly used. Through hole LEDs are likely to become increasingly popular in a variety of applications as technology continues to advance.
