DEVELOPMENT OF A MICROCONTROLED IRRADIATION SYSTEM BASED ON LIGHT-EMITTING DIODES (LEDs) MATRIXES FOR PHOTOTHERAPY APPLICATIONS

Abstract

Light Emitting Diodes (LED´s) are semiconductor devices that explore the concepts of physics of semiconductor materials and the theory of bands to efficiently convert electrical energy into electromagnetic radiation. Currently the LED´s are devices widely employed in electronics, and their applications can range from simple lighting design, light communication apparatus and sensors to the development of lighting systems for medical purpose. We can mention as an example of medical purposes, devices based on LED´s used in light-mediated therapies such as Phototherapy. This paper describes a prototype of a microcontrolled irradiation system based on LED´s matrix to be used in the treatment of skin healing, more specifically in the treatment of oral mucositis.
