Light Therapy For Pain Relief

LED with respect to Light Therapy, they are non-coherent, that is, the light does not remain in a coherent shape as it travels to its target. Instead, it disperses from the light unit immediately into a wider shape as it travels to its target. It is further dispersed upon reaching the target and absorbed into the surrounding skin and tissue.

This dispersion increases with distance; the light does not remain in the shape and size of the diode emitting it as it leaves the diode. It does not, therefore, cause soft tissue damage.
(Think of a flashlight in a dark room. If it is turned on, but placed on the floor, the room remains dark. If it is lifted, pulled away from the floor, the light disperses into a shape that lights the room).

Because of our advanced technology, we are able to achieve the results we seek without the use of a soft laser. (The development of this technology is similar to the evolution of computers. The first ones took up entire rooms and cost more than a large fortune. Today’s products cost far less and do exponentially more.)
Soft laser light is coherent; it remains in the same cylindrical shape from its source to its target and disperses only after contact with that target. This type of light is highly regulated by the Federal Drug Administration (FDA) because it can be very dangerous. Soft tissue can be burned and otherwise damaged.
