System and method for the photodynamic treatment of burns, wounds, and related skin disorders
A method including photomodulating mammalian tissue with more than one light source of narrowband, multi chromatic electromagnetic radiation, wherein at least one light source emits radiation at a wavelength corresponding to yellow light and at least one light source emits radiation corresponding to infra-red light, wherein the ratio of the intensity of yellow light to infra-red light is about 4:1.
1. A method, comprising:
photomodulating mammalian tissue with more than one light source of narrowband, multi chromatic electromagnetic radiation,
wherein at least one light source emits radiation at a wavelength corresponding to yellow light and at least one light source emits radiation corresponding to infra-red light, and the yellow light is emitted at a greater intensity than the infra-red light, and
wherein the tissue is exposed to an energy fluence of less than 4 J/cm 2 .
2. The method of claim 1 , wherein at least one light source emits radiation having a dominant emissive wavelength of 580 nm to 600 nm and at least one light source emits radiation having a dominant emissive wavelength of 850 nm to 950 nm.
3. The method of claim 2 , wherein the at least one light source emits radiation having a dominant emissive wavelength of 590 nm at an energy output of 4 mW/cm 2 and at least one light source emits radiation having a dominant emissive wavelength of 850 nm at an energy output of 1 mW/cm 2 .
4. The method of claim 1 , comprising varying the ratio of infra-red light intensity with respect to yellow light intensity with at least one optical, mechanical, or electrical filter.
5. The method of claim 1 , wherein the ratio of the intensity of yellow light to infra-red light is 4:1.
6. The method of claim 1 , wherein the yellow light is emitted simultaneously with the infra-red light.
