Abstract
Apparatus for external medical treatment with the aid of light, including a light-emitting device to be held against or in close proximity to a patient's body. The device includes light-emitting diodes that emit monochromatic light over one or more predetermined time periods and that pulsate the emitted light in accordance with a predetermined pulse frequency or a series of pulse frequencies over the predetermined time periods. The light-emitting device includes a casing and a plate that carries the light-emitting diodes. An eccentric drive arrangement is provided and includes a first part that is fixed relative to the casing and a second part that is connected to the plate. A spring prevents rotation of the plate. An electric motor powers the eccentric drive arrangement to cause the plate carrying the light-emitting diodes to execute an oscillatory movement.
