Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThis paper presents a study on the application of high-brightness LED (Light Emitting Diode)to health care. The LEDs are supplied by electronic converters, proposed in order to analyze the light emitted by the LEDs and their interaction with human tissues. Throughout the work, a comparative study between the LED and LASER and their actions on human tissue is presented. Also, a study on the influence of frequency, duty cycle and the radiated power on the wavelength of light emitted by LEDs was conducted. The assesment of the effects of blue and red light emitted by high-brightness LEDs in real cases made the conclusions consistent and promising. The research work also comprises a ext...
