Abstract
Abstract A combined work station and phototherapy unit in which the fixture containing the light source is mounted on a vertical support to be placed on the base of the open area for work to be performed, the fixture being at an angle, preferably in the range of 30°-60°, so that the user will not be staring directly into the light from the fixture. There will be light both impringing upon the eyes of the user for photobiological effect and also light will be directed to the work area.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
148 words
A combined work station and phototherapy unit for use by a person comprising: a portable base unit having vertically extending support means to rest on a surface and define an interior work space which is to be illuminated, a light fixture associated with said base unit having at least one electric lamp therein for producing a visible light output, and means for mounting said light fixture to said base unit to be located above said work space and to place said electric lamp at an angle in the range of between about 30° to about 60° relative to the horizontal and at a height to supply the visible light output produced by the lamp to a person working at the place where the work station is located both in line and at least in part from a superior position relative to the line of sight of the person.
Claim 2
Dependent Claim
148 words
A combined work station and phototherapy unit for use by a person comprising: a portable base unit having vertically extending support means to rest on a surface and define an interior work space which is to be illuminated, a light fixture associated with said base unit having at least one electric lamp therein for producing a visible light output, and means for mounting said light fixture to said base unit to be located above said work space and to place said electric lamp at an angle in the range of between about 30° to about 60° relative to the horizontal and at a height to supply the visible light output produced by the lamp to a person working at the place where the work station is located both in line and at least in part from a superior position relative to the line of sight of the person.
Claim 3
Dependent Claim
25 words
The combined work station and phototherapy unit of claim 1 wherein said vertically extending supports are walls which define a generally rectangular work space area.
Claim 4
Dependent Claim
29 words
The combined work station and phototherapy unit of claim 2 wherein said base unit includes a base member, and back and side walls hingedly connected to said base member.
Claim 5
Dependent Claim
23 words
The combined work station and phototherapy unit of claim 1 wherein said electric lamp of said fixture comprises a bank of fluorescent lamps.
Claim 6
Dependent Claim
32 words
The combined work station and phototherapy unit of claim 4 further comprising means for switching various ones of said fluorescent lamps on and off to control the intensity of the light output.
Claim 7
Dependent Claim
23 words
The combined work station and phototherapy unit of claim 4 wherein said fluorescent lamps produce a full spectrum energy output including ultraviolet energy.
Claim 8
Dependent Claim
23 words
The combined work station and phototherapy unit of claim 4 wherein said fluorescent lamps produce a daylight spectrum energy output without ultraviolet energy.
Claim 9
Dependent Claim
32 words
The combined work station and phototherapy unit of claim 4 wherein said fluorescent lamps produce a distribution of narrow spectral bands which increases lumen output and approximately doubles illuminance at the eye.
Claim 10
Dependent Claim
28 words
The combined work station and phototherapy unit of claim 4, further comprising means for detachably mounting said light fixture to said vertically extending walls of said base unit.
Claim 11
Dependent Claim
41 words
The combined work station and phototherapy unit of claim 4 further comprising means for attaching said light fixture to said vertically extending walls of said base unit, said attaching means permitting said fixture to be rotated relative to said work station.
Claim 12
Dependent Claim
31 words
The combined work station and phototherapy unit of claim 1 wherein said fixture is mounted at an angle in the range of between about 40° and 45° relative to the horizontal.
Claim 13
Dependent Claim
45 words
The combined work station and phototherapy unit of claim 11 further comprising means for detachably mounting the fixture to the base unit including at least one extending arm on one of the light fixture and base unit and mating arm receiving means on the other.
Claim 14
Dependent Claim
19 words
The combined work station and phototherapy unit of claim 11 and further comprising diffuser means on said fixture means.
Claim 15
Dependent Claim
48 words
The combined work station and phototherapy unit of claim 1 wherein the light fixture supplies visible light at an intensity in the range from about 2,500 to about 10,000 lumens with the person positioned at a normal working distance relative to the work space of the work station.
Claim 16
Dependent Claim
34 words
The combined work station and phototherapy unit of claim 14 wherein the light fixtures supplies about 10,000 lumens of visible light to the user position at a normal distance relative to the work station.
Claim 17
Dependent Claim
28 words
The combined work station and phototherapy unit of claim 4 wherein the fluorescent lamps of said bank of lamps are elongated and extend the length of the fixture.
Claim 18
Dependent Claim
44 words
The combined work station and phototherapy unit of claim 1 wherein said means for mounting said light fixture to said base unit comprises removable mounting means and means for assembling said lamp fixture to said base unit to be moved as a combined unit.
Claim 19
Dependent Claim
31 words
The combined work station and phototherapy unit of claim 1 wherein a portion of the visible light produced by the electric lamp is directed to the work space for its illumination.
