An example phototherapy system includes a handle and a phototherapy light source. The phototherapy light source is attached to the handle, adapted to emit a light in a therapeutic wavelength, and includes a plasma lamp. The plasma lamp can be disposed between sheets of transparent material, including quartz. The phototherapy light source can be adapted to emit a light in a UVB wavelength between about 300 nanometers and about 320 nanometers and can have an output of between about 15 mW/cm2 and about 21 mW/cm2. ## Claims ### Claim 1 A phototherapy system having a first, deactivated state and a second, activated state, the phototherapy system comprising: a handle having a first portion and a second portion, the first portion defining a first recess and a first opening, and the second portion defining a second recess and a second opening; and a phototherapy light source attached to the handle and adapted to emit a light in a therapeutic wavelength, the phototherapy light source including first and second sheets of transparent material, each of the first and second sheets of transparent material disposed through one of the first and second openings and extending from the handle, the phototherapy light source having an on state and an off state and comprising a plurality of light emitting diodes, each light emitting diode of the plurality of light emitting diodes having an on state and an off state; wherein the plurality of light emitting diodes is disposed between the first and second sheets of transparent material; and wherein the phototherapy system is configured such that each light emitting diode of the plurality of light emitting diodes moves from the on state to the off state simultaneously when the phototherapy system is moved from the first, deactivated state to the second, activated state and such that each light emitting diode of the plurality of light emitting diodes moves from the on state to the off state independently of the state of the remaining light emitting diodes of the plurality of light emitting diodes when the phototherapy system is moved from the second, activated state to the first, deactivated state. ### Claim 2 (depends on 1) The phototherapy system of claim 1, wherein a first light emitting diode of the plurality of light emitting diodes has a first predetermined treatment time; and wherein a second light emitting diode of the plurality of light emitting diodes has a second predetermined treatment time that is different than the first predetermined treatment time. ### Claim 3 (depends on 1) The phototherapy system of claim 1, wherein a characteristic of each light emitting diode of the plurality of light emitting diodes is selected from a group consisting of a color temperature, an output, and a voltage. ### Claim 4 (depends on 1) The phototherapy system of claim 1, wherein the phototherapy light source is adapted to have an output of 16 mW/cm2. ### Claim 5 (depends on 1) The phototherapy system of claim 1, wherein the therapeutic wavelength is a UVB wavelength. ### Claim 6 (depends on 5) The phototherapy system of claim 5, wherein the UVB wavelength is between 300 nanometers and 320 nanometers. ### Claim 7 (depends on 5) The phototherapy system of claim 5, wherein the UVB wavelength is 308 nanometers. ### Claim 8 (depends on 1) The phototherapy system of claim 1, wherein at least one of the first and second sheets of transparent materials comprises quartz. ### Claim 9 (depends on 1) The phototherapy system of claim 1, wherein each of the first and second sheets of transparent material comprises quartz. ### Claim 10 (depends on 1) The phototherapy system of claim 1, wherein the phototherapy light source is adapted to emit a light in only the therapeutic wavelength. ### Claim 11 (depends on 1) The phototherapy system of claim 1, further comprising a camera attached to the phototherapy light source. ### Claim 12 (depends on 11) The phototherapy system of claim 11, wherein the camera is positioned at the center of the first sheet of transparent material. ### Claim 13 (depends on 1) The phototherapy system of claim 1, further comprising a positioning sensor attached to the handle. ### Claim 14 (depends on 1) The phototherapy system of claim 1, further comprising a lamp comprising the plurality of light emitting diodes. ### Claim 15 (depends on 14) The phototherapy system of claim 14, wherein the lamp is disposed between the first sheet of transparent material and the second sheet of transparent material. ### Claim 16 (depends on 15) The phototherapy system of claim 15, wherein at least one of the first sheet of transparent material and the second sheet of transparent material comprises quartz.
