Abstract
An apparatus for applying light radiation to an object include: a source of light radiation including infrared radiation, a light guide having a proximal end optically coupled to the source of light radiation and a distal end with a light radiation emitting end surface, a power supply which supplies power to the light radiation source, a photo light energy detector disposed within the apparatus so as to receive energy output emitted from the light radiation source, the photo light energy detector producing an output in response to the received energy output; and a controller coupled to the photo light energy detector and the light radiation source; wherein the controller receives the output from the photo light energy detector and controls the source of light radiation to produce a predetermined light radiation intensity in response to the output.
