Abstract
A phototherapy system and method for automatically replacing a failed light source with a new light source once a failure of a first light source is detected. This system permits the new light source to assume a coaxially aligned position with the proximal end portion of a light transmission medium in place of the failed light source without any manual input by the user. In addition, an improved coupling system is provided for coupling the light transmission medium to the illumination device housing the light sources. The coupling system prevents pull out of the light transmission medium from the illumination device over nearly all rotational angles of the proximal end of the light transmission medium relative to the housing, and over only a relatively small range of angles will some degree of pull out force enable the light transmission medium to be decoupled from the illumination device.
