Medical apparatus

1. Apparatus for use in therapeutic and cosmetic treatment, the apparatus comprising:

a casing;

electronics located within or attached to the casing;

at least one light source;

a chassis located within the casing wherein along at least part of or substantially the whole length of the chassis there are channels on at least one or both sides of the chassis which support a flexible electronic substrate; and

wherein the casing and electronic substrate adapt and conform to a non-planar surface.

2. Apparatus according to claim 1 , wherein the channels support the flexible electronic substrate and allowing the flexible electronic substrate to be free or substantially free to move along the channels.

3. Apparatus according to claim 1 wherein the channels allow an upper chassis and lower chassis to bend in tandem or substantially in tandem with the flexible electronic substrate being free or substantially free to move along the channels during bending and flexing.

4. Apparatus according to claim 1 , wherein diffusers are also arranged and located in the casing so that the diffusers are free or substantially free to move along the channels.

5. Apparatus according to claim 1 , wherein there is a protruding member in a chassis of the casing which functions as a runner for a flexible electronic substrate.

6. Apparatus according to claim 1 , wherein the apparatus comprises a flexible electronic substrate which has a cut-away area (e.g. a notch) through which a protruding member is extendable and allows the flexible electronic substrate to move relative to the protruding member when the apparatus is bent and flexed.

7. Apparatus according to claim 5 , wherein a flexible electronic substrate moves along the protruding member thereby allowing the chassis and the flexible electronic substrate to bend and flex in tandem or substantially in tandem.

8. Apparatus according to claim 1 , wherein the casing comprises at least one or a series of hinges that allow the apparatus to bend and flex.

9. Apparatus according to claim 1 , wherein there are at least two or more light diffusers which are capable of providing improved homogeneity for illumination provided by the at least one light source.

10. Apparatus according to claim 1 , wherein there is a plurality of light diffusers.

11. Apparatus according to claim 1 , wherein the two or more light diffusers are oriented in a parallel or substantially parallel orientation in the casing.

12. Apparatus according to claim 1 , wherein there are three or more or a plurality of light diffusers which are in a parallel or substantially parallel orientation in the casing.

13. Apparatus according to claim 1 , wherein there are two or more light diffusers located in a chassis using any form of suitable attachment means such as mechanical and adhesive means.

14. Apparatus according to claim 13 , wherein the chassis is flexible thereby allowing the apparatus to adapt and conform to a non-planar surface such as on a patient.

15. Apparatus according to claim 1 , wherein there is a plurality of light sources located within the casing.

16. Apparatus according to claim 1 , wherein the light sources are LEDs or OLEDS, and wherein there are two or more light diffusers which are spaced apart by about 1-10 mm or about 4 mm.

17. Apparatus according to claim 1 , wherein the casing comprises an upper chassis and a lower chassis within which the light emitting apparatus is located, and wherein located within the casing there is a flexible PCB.

18. Apparatus according to claim 1 , wherein the casing comprises a series of hinges which are capable of allowing the apparatus to bend, and wherein the casing comprises a housing area within which a PCB is located.

19. Apparatus according to claim 1 , wherein the apparatus comprises a drug and chemical source capable of delivering drugs and chemicals to an area of the patient to be treated, and wherein the channels maintain a constant or substantially constant distance between the at least one light source or a plurality of light sources and a light diffuser.

20. A method of performing a therapeutic and cosmetic treatment, the method comprising:

providing a casing;

providing electronics located within or attached to the casing;

providing at least one light source;

a chassis located within the casing wherein along at least part of or substantially the whole length of the chassis there are channels on at least one or both sides of the chassis which support a flexible electronic substrate; and

wherein the casing and electronic substrate adapt and conform to a non-planar surface.
