## Abstract

Light therapy apparatuses are configured to expose a subject to light that is tailored to address and/or diagnose at least one motor-related neurological condition. Blue-green light and green light are useful for treating motor-related neurological conditions or their symptoms. Deep red light and near infrared radiation may facilitate the repair of retinal cells and/or neurons that may be responsible for motor-related neurological conditions. Amber, orange and red light enable the early diagnosis of motor-related neurological conditions.

## Claims

### Claim 1

A system for administering light therapy, comprising:
a first light source that emits a first peak of visible light in a range of 460 nm to 520 nm; and
a second light source that emits a second peak of visible light in a range of above 520 nm to less than 540 nm,
at least one of the first peak of visible light emitted by the first light source and the second peak of visible light emitted by the second light source exceeding an intensity of a corresponding bandwidth in standard indoor lighting at 500 lux.

### Claim 2 (depends on 1)

The system of claim 1, wherein the system emits substantially no light outside of a range of 460 nm to 570 nm.

### Claim 3 (depends on 2)

The system of claim 2, further comprising:
at least one filter for limiting emission of extraneous wavelengths of visible light from at least one of the first light source and the second light source.

### Claim 4 (depends on 3)

The system of claim 3, wherein the at least one filter limits passage of the extraneous wavelengths of visible light through the filter to ambient or below ambient amounts.

### Claim 5 (depends on 3)

The system of claim 3, wherein the at least one filter prevents passage of the extraneous wavelengths of visible light through the filter.

### Claim 6 (depends on 3)

The system of claim 3, wherein the at least one filter limits an intensity of the extraneous wavelengths of visible light emitted beyond the at least one light source to a subject in such a way that a collective intensity of each peak of the extraneous wavelengths of visible light is less than a collective intensity of the intensity peak of the at least one first bandwidth of visible light.

### Claim 7 (depends on 3)

The system of claim 3, wherein at least one of the first light source and the second light source comprises a source of white light.

### Claim 8

A system for administering light therapy, comprising:
a first light source that emits an above ambient intensity of at least one first bandwidth of visible light including a first intensity peak at a wavelength in a range of 460 nm to 520 nm, the above ambient intensity of the at least one first bandwidth exceeding an intensity of the at least one first bandwidth in standard indoor lighting at 500 lux; and
a second light source that emits an above ambient intensity of at least one second bandwidth of visible light including a second intensity peak at a wavelength in a range of above 520 nm to less than 540 nm, the above ambient intensity of the at least one second bandwidth exceeding an intensity of the at least one second bandwidth in standard indoor lighting at 500 lux.

### Claim 9 (depends on 8)

The system of claim 8, wherein the system emits substantially no light in a range of greater than 570 nm to 750 nm.

### Claim 10 (depends on 8)

The system of claim 8, further comprising:
at least one filter for limiting emission of extraneous wavelengths of visible light having wavelengths of greater than 570 nm to 750 nm by at least one of the first light source and the second light source.

### Claim 11 (depends on 10)

The system of claim 10, wherein the at least one filter limits passage of the extraneous wavelengths of visible light through the filter to ambient or below ambient amounts.

### Claim 12 (depends on 10)

The system of claim 10, wherein the at least one filter prevents passage of the extraneous wavelengths of visible light through the filter.

### Claim 13 (depends on 10)

The system of claim 10, wherein the at least one filter limits an intensity of the extraneous wavelengths of visible light emitted beyond the at least one of the first light source and the second light source to a subject in such a way that a collective intensity of each peak of the extraneous wavelengths of visible light is less than a collective intensity of the first intensity peak of the at least one first bandwidth of visible light and less than a collective intensity of the second intensity peak of the at least one second bandwidth of visible light.

### Claim 14 (depends on 10)

The system of claim 10, wherein at least one of the first light source and the second light source comprises a source of white light.

### Claim 15

A system for administering light therapy, comprising:
at least one first light source that emits at least one first bandwidth of visible light including a first intensity peak at a wavelength in a range of 460 nm to 520 nm, an intensity of the first intensity peak exceeding an intensity of a corresponding bandwidth in standard indoor lighting at 500 lux, each peak of visible light below 460 nm emitted by the light source, and an intensity of each peak of visible light above 570 nm emitted by the at least one light source; and
at least one second light source that emits at least one second bandwidth of visible light including a second intensity peak at a wavelength in a range of above 520 nm to less than 540 nm, an intensity of the second intensity peak exceeding an intensity of a corresponding bandwidth in standard indoor lighting at 500 lux, each peak of visible light below 460 nm emitted by the light source, and an intensity of each peak of visible light above 570 nm emitted by the at least one light source.

### Claim 16 (depends on 15)

The system of claim 15, wherein the system does not emit light in a range of above 570 nm to 750 nm.

### Claim 17 (depends on 15)
