Abstract

Phototherapy systems comprising a therapeutic lamp platform for radiant lamps such as LEDs disposed in a holdable spot applicator assembly, the holdable spot applicator assembly including a reflective surface facing towards a patient and a plurality of LEDs for communicating lamp radiation from the lamps to a user. The lamps and associated circuitry are housed within a holdable elongated structure.

First claim

What is claimed is:

1. A phototherapy device comprising:
a body including a longitudinal length extending between a first end of the body and a second end of the body, the body housing a plurality of radiant lamps having a mixed combination of different wavelength radiant energy proximately located near the first end of the body;
a first end surface located at the first end of the body, the first end surface including a concave surface and a radiant energy communication area recessed from a protruding peripheral surface of the first end surface, the concave surface and radiant energy communication area configured to direct the radiant energy from the plurality of radiant lamps to a user treatment area, wherein the first end surface traps the radiant energy from the plurality of radiant lamps within a confine limited by the concave surface, the recessed radiant energy communication area, the protruding peripheral surface of the first end surface and the user treatment area with the first end surface in contact with an area about the user treatment area; and
a second end surface located at the second end of the body;
wherein the protruding peripheral surface is configured to direct the radiant energy from the plurality of radiant lamps at a non-normal incident angle relative to the user treatment area with the protruding peripheral surface in contact with the area about the user treatment area.

2. The phototherapy device according to claim 1 , the body further comprising:
a main circuit board housed within the body;
one or more batteries; and
a control button,
wherein the main circuit board, the one or more batteries and the control button are operatively connected to control the plurality of radiant lamps.

3. The phototherapy device according to claim 1 , further comprising:
a fixed cover over the plurality of radiant lamps, the fixed cover transparent to the radiant energy communicated from the plurality of radiant lamps to the user treatment area.

4. The phototherapy device according to claim 1 , wherein the concave surface includes one or more apertures for communicating the radiant energy to the user treatment area.

5. The phototherapy device according to claim 1 , further comprising:
a controller configured to control a radiant energy dosage time duration.

6. The phototherapy device according to claim 5 , wherein the radiant energy dosage time duration is 2 minutes to 3 minutes.

7. The phototherapy device according to claim 1 , the body further comprising:
a single battery housed within the body; and
a step-up voltage circuit operatively associated with the single battery and one or more of the plurality of radiant lamps, the step-up voltage circuit configured to step-up a voltage provided by the single battery to drive one or more of the plurality of radiant lamps.

8. A phototherapy device comprising:
a body including a longitudinal length extending between a first end of the body and a second end of the body, the body housing one or more radiant lamps proximately located near the first end of the body, the one or more radiant lamps disposed to communicate radiant energy to a user treatment area;
a first end surface located at the first end of the body, the first end surface including a concave surface and a radiant energy communication area recessed from a protruding peripheral surface of the first end surface, the concave surface and radiant energy communication area configured to direct the radiant energy from the one or more radiant lamps to the user treatment area, wherein the first end surface traps the radiant energy from the one or more radiant lamps within a confine limited by the concave surface, the recessed radiant energy communication area, the protruding peripheral surface of the first end surface and the user treatment area with the first end surface in contact with an area about the user treatment area; and
a second end surface located at the second end of the body;
wherein the protruding peripheral is configured to direct the radiant energy from the one or more radiant lamps at a non-normal incident angle relative to the user treatment area with the protruding peripheral surface in contact with the area about the user treatment area.

9. The phototherapy device according to claim 8 , the body further comprising:
a main circuit board housed within the body;
one or more batteries; and
a control button,
wherein the main circuit board, the one or more batteries and the control button are operatively connected to control the one or more radiant lamps.

10. The phototherapy device according to claim 8 , further comprising:
a fixed cover over the plurality of radiant lamps, the fixed cover transparent to the radiant energy communicated from the one or more radiant lamps to the user treatment area.

11. The phototherapy device according to claim 8 , wherein the concave surface includes one or more apertures for communicating the radiant energy to the user treatment area.

12. The phototherapy device according to claim 8 , further comprising:
a controller configured to control a radiant energy dosage time duration.

13. The phototherapy device according to claim 12 , wherein the radiant energy dosage time duration is 2 minutes to 3 minutes.

14. The phototherapy device according to claim 8 , the body further comprising:
a single battery housed within the body; and
a step-up voltage circuit operatively associated with the single battery and one or more of the plurality of radiant lamps, the step-up voltage circuit configured to step-up a voltage provided by the single battery to drive the one or more radiant lamps.
