Daylight tracking simulator and/or phototherapy device

1. A method of controlling spectral output of a lamp-comprising light sources selected from the group consisting of a fluorescent light source and an LED light source, the light sources including at least one light-generating mechanism which differs from at least one other light-generating mechanism, the method comprising:

specifying a first spectral output frequency greater than zero for a first geographic location and specifying a second spectral output frequency greater than zero for a second geographic location;

determining a geographic location of the lamp;

comparing the geographic location of the lamp to at least the first geographic location or the second geographic location;

determining a desired spectral output frequency based on the comparison of the geographic location of the lamp to at least the first geographic location or the second geographic location; and

controlling the spectral output of the lamp based on a user preference, the user preference assigning a priority of control between the determined desired spectral output frequency, a switch position of the lamp, and a determined calendar setting.

2. The method as claimed in claim 1 , further comprising detecting a frequency of illumination generated by a light source among the light sources.

3. The method as claimed in claim 1 , further comprising monitoring the spectral output of each of the light sources.

4. The method as claimed in claim 1 , wherein the controlling comprises applying a percentage allocation of each of the light sources while varying illumination intensity of the light sources at a constant level.

5. A non-transitory computer-readable medium storing instructions which, when executed by a processor, cause the processor to:

determine a geographic location of the lamp comprising light sources selected from the group consisting of a fluorescent light source and an LED light source, the light sources including at least one light-generating mechanism which differs from at least one other light-generating mechanism;

compare the geographic location of the lamp to at least a first stored geographic location or a second stored geographic location;

determine a desired spectral output frequency greater than zero based on the comparison of the geographic location of the lamp to at least the first geographic location or the second geographic location; and

control the spectral output of the light sources based on a user preference, the user preference assigning a priority of control between the determined desired spectral output frequency, a switch position of the lamp, and a determined calendar setting.

6. The medium as claimed in claim 5 , wherein the control step comprises applying a percentage allocation of each of the light sources while varying illumination intensity of the light sources at a constant level.

7. A fluorescent or light emitting diode-based system for generating light flux comprising:

a lamp comprising:

a plurality of light sources for illuminating an area, the light sources including a plurality of light-generating mechanisms at least one of which is different from the remainder, at least one of the light-generating mechanisms comprising at least one of a fluorescent light source or an LED light source; and

a light source controller electrically coupled with the light sources and arranged to control the spectral output of the light sources, the light source controller being arranged to apply a percentage allocation of each of the light sources while varying illumination intensity of the light sources at a constant level;

a power supply;

a switch electrically coupled between the lamp and the power supply and arranged to control the supply of power from the power supply to the lamp; and

a position determination system configured to determine a geographic location of the system, specify a first spectral output frequency greater than zero for a first geographic location and specify a second spectral output frequency greater than zero for a second geographic location, compare the geographic location of the system to at least the first geographic location or the second geographic location; determine a desired spectral output frequency based on the comparison of the geographic location of the system to at least the first geographic location or the second geographic location; and

the light source controller configured to determine the spectral output of the light sources based on a user preference, the user preference assigning a priority of control between the determined spectral output frequency, a switch position of the lamp, and a determined calendar setting.
