Infrared LED light beads and ordinary LED light beads are semiconductor light-emitting diode, the main difference comes from the chip process is different, the specific differences are as follows:

Different light-emitting principle Ordinary LED light bead chip mainly emits visible light, light-emitting principle is the carrier in the conduction band and the valence band between the energy level jump, send photons. Infrared LED light beads are mainly invisible near-infrared light, the light-emitting mechanism is the carrier jump in the doped state between.

Different materials Ordinary LED beads are mainly GaAs, GaP and other materials, emitting a variety of visible light. Infrared LED beads are usually GaAs, InGaAs, AlGaAs, etc., emitting 700-2500nm of near-infrared light.

Working voltage is different Due to different chip materials and processes, the luminous efficiency of infrared light beads is lower than that of blue and red light, and the positive conduction voltage drop is about 1.2-2V, which is smaller than that of ordinary LEDs, which is 2.2-3V.

Application areas are different Ordinary LEDs are used for lighting, display and other applications that require visible light, in the life of the very Jue. Infrared LEDs emit invisible light, commonly used in night vision equipment, remote control, sensors, vision detection and other applications requiring infrared light, mostly used in industrial areas.
