Invisible infrared LED, also known as invisible infrared diode, is a type of LED that emits infrared light without visible light. It has been widely used in various fields such as security, remote control, and medical treatment. In this article, we will introduce the industry of invisible infrared LED, including its working principle, applications, market prospects, and challenges.

Working Principle of Invisible Infrared LED

The working principle of invisible infrared LED is based on the semiconductor material. When the forward voltage is applied to the semiconductor material, electrons and holes are excited, and the recombination of electrons and holes emits infrared light. The key to making the infrared light invisible is to control the wavelength of the emitted light. The invisible infrared LED emits light in the infrared band, which is outside the visible light range of the human eye, so it is not visible to the naked eye.
