Assembly for photodynamic therapy

A system for photomedicine therapy comprising:

• a. at least partially transparent body having an internal cavity;
• said internal cavity is provided with input and output pipes configured for circulating a cooling agent via said internal cavity;
• b. at least one electrically energizable halogen lamp disposed within said internal cavity of said body containing said cooling agent such that radiation from said at least one electrically energizable—halogen lamp propagates to the ambient surroundings through said cooling agent while cooling said halogen lamp;
• c. a cooling circuit further comprising a pump and heat radiator fluidly connected with said internal cavity in a close-loop manner.

A method of providing photomedicine therapy to a patient, said method comprising the steps of:

• a. providing an assembly for photomedicine therapy comprising:
• i. at least partially transparent body having an internal cavity;
• said cavity configured for mounting a halogen lamp;
• said internal cavity is provided with input and output pipes configured for circulating a cooling agent through a pump and a heat radiator via said internal cavity in a close-loop manner;
• ii. at least one electrically energizable halogen lamp disposed within said cavity such that light from said at least one electrically powerable halogen lamp passes to the ambient surroundings through said cooling agent while cooling said halogen lamp;
• b. positioning said assembly adjacent a patient;
• c. illuminating said assembly for a period of time;
• and,
• d. circulating a coloured cooling agent within said body;
• wherein power density provided by the light source in a treatment plane is from 0.1 watts/cm2 to 2.0 watts/cm2 over an area of 60 cm2.
