Abstract

The present invention relates to an induction driven light module. In particular, the present invention is directed to an induction driven LED or LD module for photodynamic therapy, entertainment or decoration. The present invention also relates to a method for treating cancer, tumor or other ailments.

Claims

1. An induction driven light module comprising (a) at least one light generating device operably linked or coupled to a driver induced by alternating magnetic field, and (b) a packaging material to cover or seal the component (a).

2. The module of claim 1 wherein the light generating device is a light-emitting diode or a laser diode.

3. The module of claim 2 wherein the light-emitting diode or laser diode provides low or high irradiation power.

4. The module of claim 1 wherein the driver is induced by low frequency alternating magnetic field or RF power with frequencies that can easily penetrate human body.

5. The module of claim 1, wherein the packaging material is selected from the group consisting of polyurethane, polyester, polycarbonate, polylactic acid, polyglycolic acid, poly(lactide-co-glycolide), poly(.epsilon.-caprolactone), polyethyleneimine, polystyrene, polyamide, rubber, nylon, TEFLON®

, silicone rubber, polyacrylonitrile, polyacrylate, and polymetacrylate, poly(alpha-hydroxy acid), poly(dioxanone), poly(orthoester), poly(ether-ester), poly(lactone), polytetrafluoroethylene, organosilane, mixtures thereof and copolymers thereof.

6. The module of claim 5, wherein the packaging material is a material selected from the group consisting of polyurethane, polyester and polycarbonate.

7. The module of claim 6, wherein the packaging material is semi-transparent or transparent.

8. The module of claim 1, which is applied to entertainment, decoration or colored light generation.

9. The module of claim 1, which is applied to articles for entertainment, decoration or colored light generation.

10. A method for treating a subject suffering cancer, tumor, or selected tissues comprising (a) implanting the induction driven light module of claim 1 into a tissue nearby or adjacent to cancer, tumor or selected tissues of the subject;

(b) administering a photosensitizer on cancer, tumor or selected tissues;

(c) driving the light module through the induction of alternating magnetic field; and

(d) irradiating cancer, tumor, or selected tissues by the driven light generating device.

11. The method of claim 10 wherein the tissue is breast, brain, liver, kidney, stomach, pancreas, intestine, spleen, bone marrow, joints, heart, lung or body parts that are difficult to be accessed with endoscopy.

12. The method of claim 10 wherein the light is originated from a light-emitting diode or a laser diode.

13. The method of claim 12 wherein the light-emitting diode or laser diode provides low irradiation power.

14. The method of claim 12 wherein the light-emitting diode or laser diode provides high irradiation power.

15. The method of claim 10 wherein the driving the light module is induced by low frequency alternating magnetic field or RF power with frequencies that can easily penetrate human body.

16. The method of claim 13 wherein the irradiation is long term.

17. The method of claim 14 wherein the irradiation is short term.

18. A method of treating angiogenesis in a subject comprising (a) implanting the induction driven light module of claim 1 into a tissue nearby or adjacent to blood vessel of the subject;

(b) administering a photosensitizer on cancer, tumor or selected tissues;

(c) driving the light module through inducing of alternating magnetic field; and

(d) irradiating cancer, tumor or selected tissues by the driven light generating device.

19. The method of claim 18 wherein the light is a light-emitting diode or a laser diode.

20. The method of claim 18 wherein the treatment is directed to cavernous hemangioma or hemangioendothelioma.
