Phototherapy treatment devices for applying area lighting to a wound
First Claim
1. A phototherapy treatment device comprising an area light emitter, means for positioning the light emitter in close proximity to a wound of a patient, and means for causing light to be emitted from the light emitter towards the wound for applying light energy to the wound, wherein the light emitter comprises a light guide that receives light from a light source and causes light to be reflected or refracted out of the light guide toward the wound, the light guide including a plurality of optical fibers of different lengths terminating at respective ends at different locations over the length and width of the light guide to cause light to be emitted from the ends of the optical fibers and reflected toward the wound in a pinpoint pattern at different points over the length and width of the light guide.

Abstract
Phototherapy treatment devices include a light emitter that is adapted to be placed in close proximity to a wound for applying light/heat energy to the wound to aid in the healing process. The light emitter may comprise a light guide that receives light from a light source or a light source that is affixed to a substrate used to position the light source over the wound.
