Introduction to 5V IR LED Industry

1. Definition and Basic Characteristics of 5V IR LED

The 5V IR LED, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when a forward voltage of 5V is applied. It is widely used in various fields, such as security, remote control, and communication. The basic characteristics of 5V IR LED include: 1. Low forward voltage: The typical forward voltage of a 5V IR LED is around 1.2V to 1.5V. 2. High brightness: The brightness of a 5V IR LED is generally higher than that of a common LED. 3. Wide wavelength range: The wavelength of the emitted light can range from 780nm to 950nm, which is within the infrared spectrum. 4. Long lifespan: The lifespan of a 5V IR LED can reach tens of thousands of hours.

2. Working Principle of 5V IR LED

The working principle of a 5V IR LED is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are injected into the depletion region, which is formed at the junction of the P-type and N-type semiconductor materials. Under the action of the electric field, electrons and holes recombine, and the energy released during the recombination is converted into light energy. The infrared light emitted by the 5V IR LED is then transmitted through the lens or other optical components.

3. Applications of 5V IR LED

The 5V IR LED has a wide range of applications, including: 1. Security: 5V IR LED is commonly used in security systems, such as motion sensors, doorbells, and remote controls. 2.
