Introduction to the 4mm Infrared LED Industry

What is an Infrared LED 4mm?

An infrared LED 4mm, also known as a 4mm infrared light-emitting diode, is a type of electronic component that emits infrared light. These LEDs are widely used in various applications, such as remote controls, surveillance systems, and medical devices. The 4mm size of the LED makes it compact and suitable for integration into small devices and circuits. Infrared LEDs work by converting electrical energy into infrared light. When an electric current passes through the diode, it generates heat, which excites the electrons in the semiconductor material. As the electrons recombine with the holes, they release energy in the form of infrared light. The 4mm size of the LED is a standard package that ensures compatibility with various electronic devices.
