A light-emitting composite stone includes a transparent stone; a first light guide; a mounting member; an edge stone on one side of the transparent stone; a second light guide being adjacent to an inner surface of the edge stone and perpendicular to the first light guide; a light-emitting member on a bottom of the second light guide; an inclined cut on the second light guide; a first reflection member having an inclined angle of 45-degree on a bottom of the inclined cut; first and second vertical light guides; a second reflection member on a top of the first vertical light guide; a horizontal light guide between tops of the first and second vertical light guides; a third reflection member on an inner surface of a top of the second vertical light guide; and a fourth reflection member on the horizontal light guide.

Systems, devices and methods for controlled intramedullary delivery of light (frequencies from about 380 nm to about 500 nm) to treat tissue or bones disorders, including osteomyelitis, by a flexible fiber are provided, where the light is delivered in a circumferential fashion around the fiber, and where the energy delivered from the fiber is of a similar average intensity at the front end and back end of the fiber, and in between. The methods and systems deliver intramedullary light to the canal over long lengths via a minimally invasive pathway to a bone. The methods and systems deliver and maintain a light delivery system within the canal of the bone to provide single or multiple doses of light to kill, eliminate, remove or reduce bacteria, viruses, fungus and pathogens, without removal of the light fiber system, thereby providing single or multiple treatments.

A light emitting module includes: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole that, in a schematic top view, is located between the sectioning groove and the light source placement part; and a light source located in the light source placement part. A refractive index of an inside of the light adjusting hole is lower than a refractive index of the light guide member. In the schematic top view, the light adjusting hole is not positioned on a first straight line connecting a center of the light source and a farthest point in the sectioning groove, the farthest point being farthest from the center of the light source.
