Light-emitting diodes (LEDs) are much more powerful than the previous generation with quasimonochromatic outputs. These LEDs can offer target specificity to accelerate wound healing. The term “photobiomodulation,” is also used since light in the far-red to near-infrared region of the spectrum (630-1000 nm) is supposed to modulate numerous cellular functions [16-19]. Similar to LLLT, experimental results demonstrate that red and near-infrared
LED light treatment stimulates mitochondrial oxidative metabolism in vitro, augments cellular energy production, and accelerates cell and tissue repair in vivo.
