Claim 0:
1. A light treatment device for applying a light treatment to a patient's skin, the device comprising a stacked structure including:
a light source configured to emit treatment light; and
a light diffusing layer configured to receive the emitted treatment light, diffuse the treatment light, and output diffused treatment light,
wherein:
the treatment light has a wavelength within a range of 430-490 nanometers;
the light treatment device further comprising:
a housing containing the stacked structure and including an interior cavity into which the diffused treatment light is projected, and at least one opening, through which a portion of the patient may be extended into the interior cavity;
a controller configured to control the light source to adjust an intensity of the emitted treatment light based on a light intensity parameter;
a light intensity input device configured to set the light intensity parameter, wherein a user may adjust the light intensity parameter using the light intensity input device;
a light intensity output device configured to display information indicative of the light intensity parameter;
a timer;
a timer output device configured to display time information;
a heating device configured to convert electrical energy into heat and heat the interior cavity;
a temperature sensor having a temperature output that is indicative of a temperature within the interior cavity;
a temperature input device configured to set a temperature setting; and
a temperature output device configured to display at least one of the temperature setting and a temperature indicated by the temperature output;

the controller is configured to control the heating device based upon the temperature output and the temperature setting; and
the controller is configured to control a duration that the light source emits the treatment light using the timer, and the time information is indicative of the duration.
