Introduction to Invisible LED
Invisible LED (invisible LED) is a light-emitting diode, which can produce infrared light invisible to the human eye, so it is invisible in use. They are mainly used in security monitoring, night vision, automation and other fields, such as remote controls, surveillance cameras, security systems, automatic doors, automated production and so on.

"Invisible SMD LED Introduction
Invisible SMD LED refers to surface-mounted light-emitting diodes (SMD LEDs), whose light-emitting wavelength is in the infrared (IR) region and cannot be seen by the naked eye. These infrared LEDs are commonly used in various applications such as remote controls, security systems, face recognition for smartphones, gesture control, and more. Since they emit light at longer wavelengths than visible light, they cause less optical interference indoors and outdoors and can penetrate objects more effectively.

Invisible SMD LED is characterized by small size, low power consumption, high reliability, long life, fast response, maintenance-free, etc., so it has been widely used.
