The invention relates to a device for external medical treatment with light for treating different illnesses. The device comprises a light emitting means (1) arranged to abut against or be held near the body of an individual, as well as a drive device (9,10,11,12) for the light emitting means. The light emitting means comprises a cover (2) and a surface (4) carrying light emitting diodes or the corresponding (5,6), which are arranged to emit light of different wavelength intervals. The drive device (9, 10, 11, 12) is arranged to control the light emitting means (1 ) to emit one or several lights during one or several predetermined times and to, in a pulsating manner, emit the said light according to a predetermined pulse frequency or series of pulse frequencies during said times. The electric drive circuit (9,10,11,12) is adapted for controlling the light emitting diodes individually being connected to one or several of the individual light emitting diodes (5, 6) and arranged to switch them on and off so that a movable light image appears across the surface of the light emitting diode plate (4). The diode surface can have a curved shape for adaptation to the body part (8) to be treated.La présente invention concerne un dispositif pour traitement médical externe avec de la lumière, destiné à traiter différentes maladies.
