Infrared LED 8mm

Introduction to Infrared LED 8mm

The 8mm infrared LED, also known as an IR LED, is a type of semiconductor diode that emits infrared light when an electric current is applied. This light is not visible to the human eye, making it a popular choice for a variety of applications, including remote controls, security systems, and communication devices. In this article, we will delve into the details of the 8mm infrared LED, its applications, and the technology behind it.

How Infrared LED 8mm Works

An infrared LED 8mm operates on the principle of the photoelectric effect. When an electric current is passed through the diode, electrons are excited and move from the valence band to the conduction band. This movement of electrons creates a voltage difference across the diode, which emits infrared light as a byproduct. The size of the diode, in this case, 8mm, refers to the diameter of the LED's housing. The 8mm size is a standard for infrared LEDs, and it is chosen for its balance between power output and ease of use. These LEDs are compact, making them suitable for embedding into small devices such as remote controls. They are also efficient, as they convert a significant portion of electrical energy into light.
