Introduction to 5mm IR LED
What is a 5mm IR LED?
A 5mm infrared light-emitting diode (IR LED) is a type of semiconductor device that emits infrared light when an electric current is applied to it. These LEDs are commonly used in a variety of applications, including remote controls, security systems, and medical devices. The 5mm size refers to the diameter of the LED, which is a standard size for many IR LED applications.
How Does a 5mm IR LED Work?
A 5mm IR LED works by converting electrical energy into infrared light. The semiconductor material used in the LED emits photons when electrons recombine with electron holes, creating light. The wavelength of the emitted light is typically between 780nm and 950nm, which falls within the infrared spectrum. This makes 5mm IR LEDs ideal for applications that require invisible light, such as remote controls and security systems.
