Abstract

With the rapid development of semiconductors both in materials and technologies in recent years, LED has taken on a new look: higher luminous intensity, more stable peak wavelength, narrower half-wave bandwidth, better monochromaticity and orientation, and a nearly full coverage of the whole spectrum. In addition, LED devices are small in size, easy to operate and carry, and low in cost. They can be used to form complicated geometric figures so as to form point, line, and surface light sources and even flexible soft light source adaptable to the shape of a treatment area to realize evener illumination. For these reasons, LED light sources are now more and more popular in clinical practice. In this chapter, the mechanisms and indications of LED phototherapy and the status quo of the research on and development of LED phototherapy devices are introduced.
