Battery powered systems for light therapy and related methods
Battery powered light therapy systems capable of delivering 2-10 Joules per cm. sq. of light energy to a target treatment zone covering more than 700 sq. cm. of body surface area such that the light penetrates to a depth of 2 to 8 mm below a skin surface of the target treatment zone.
1 . A shape retaining, light emitting pad device for delivering light therapy to a treatment area on a human body, said device comprising:
a deformable shape-retaining member which extends around a central open area;
flexible light emitting circuitry layer comprising one or more flexible circuit boards positioned in axial alignment with the central open area of the deformable shape retaining member;
a front shield or barrier;
a rear flexible member; and
a power source comprising a rechargeable battery;
wherein:
the front shield or barrier is positioned on a front side of the flexible light emitting circuitry, said front shield or barrier comprising a translucent material which allows light emitted by flexible light emitting circuitry to pass through the front barrier or shield; and
the rear flexible member is positioned on a rear side of the flexible light emitting circuitry;
the shape of the device can be hand-shaped into a modified configuration which conforms to a shape of the human body part thereby causing bending or deformation of the shape retaining member, which thereafter causes the device to retain that modified configuration; and
the device is positionable with the front shield or barrier in juxtaposition to said treatment area so that light emitted from the flexible light emitting circuitry passes through the translucent material of the front shield or barrier and onto said treatment area.
2 . A device according to claim 1 wherein the deformable shape retaining member comprises a malleable metal.
3 . A device according to claim 1 wherein the deformable shape retaining member comprises a shape retaining plastic.
4 . A device according to claim 1 wherein the flexible light emitting circuitry comprises light emitting diodes.
5 . A device according to claim 4 wherein at least some of the light emitting diodes emit blue light.
6 . A device according to claim 4 wherein at least some of the light emitting diodes emit red light.
7 . A device according to claim 4 wherein at least some of the light emitting diodes emit infrared light.
8 . A device according to claim 1 wherein, when operating solely on power provided by the rechargeable battery, the device delivers 2-10 Joules per square centimeter of light energy to the treatment area.
9 . A device according to claim 8 wherein the size of the treatment area is more than 700 cm. sq.
10 . A device according to claim 9 wherein the device delivers said 2 to 10 Joules per cm. sq. of light energy to a depth of 25 mm below a skin surface covering said treatment area.
11 . A device according to claim 1 wherein the flexible light emitting circuitry comprises blue, red and near infrared light emitters.
12 . A device according to claim 11 further comprising a controller useable for causing the device to alternately operate in in a plurality of light treatment modes.
13 . A device according to claim 12 wherein the plurality of light treatment modes comprises:
a first mode wherein primarily or entirely blue light is emitted;
a second mode wherein primarily or entirely red light is emitted; and
a third mode wherein primarily or entirely near infrared light is emitted.
14 . A method for using a device according to claim 1 , said method comprising the steps of:
forming the device into a curved shape whereby causing bending or deformation of the shape retaining member, which then causes the device to retain that curved configuration; and
positioning the front shield or barrier in juxtaposition to said treatment area; and
operating the device solely on power provided by the rechargeable battery to cause the flexible light emitting circuitry to emit light which passes through the translucent material of the front shield or barrier and onto said treatment area.
15 . A method according to claim 14 wherein said operating of the device solely on power provided by the rechargeable battery delivers 2 to 10 Joules per cm. sq. of light energy to a depth 25 mm below a skin surface covering said treatment area.
