Abstract

A balanced blue spectrum therapy lighting fixture is provided. The lighting fixture comprises a light source and a mixture of blue light and white light within the light source having a range between approximately 90% 420-490 nm blue light and approximately 10% white light to approximately 10% 420-490 nm blue light and approximately 90% white light.

Claims

1. A balanced blue spectrum therapy lighting fixture, the lighting fixture comprising:

a light source; and

a mixture of blue light and white light within the light source having a range between approximately 90% 420-490 nm blue light and approximately 10% white light to approximately 10% 420-490 nm blue light and approximately 90% white light.

2. The lighting fixture of claim 1 wherein the blue light is 50% 420-490 nm blue light and 50% white light.

3. The lighting fixture of claim 1 and further comprising:

an array of fluorescent bulbs or L.E.D.'"'"'s, the bulbs and L.E.D.'"'"'s containing blue light and white light.

4. The lighting fixture of claim 1 and further comprising:

a single bulb with one side emitting blue light and the other side emitting white light thereby emitting a balanced light.

6. The lighting fixture of claim 1 and further comprising:

a switching mechanism for adjusting blue and white scotopic/photopic light levels thereby affecting melatonin levels.

7. The lighting fixture of claim 6 wherein in the switching mechanism is selected from the group consisting of electronic, mechanical, and radio frequency activation switching.

8. The lighting fixture of claim 1 and further comprising:

at least one color sleeve positioned over a light source for providing the blue light and white light levels.

9. The lighting fixture of claim 8 wherein the color sleeves are adjustable.

10. The lighting fixture of claim 1 wherein the blue light and white light levels are incorporated into fiber optics, one fiber for blue light and one fiber for white light.

11. The lighting fixture of claim 1 wherein the blue light and white light levels are combined with an after-glow phosphor undercoat.

12. The lighting fixture of claim 1 wherein the lighting source contains the following scotopic phosphor blend:

13. The lighting fixture of claim 12 wherein the scotopic phosphor blend comprises phosphors to give light primarily in the 400-620 nm range.

5. The lighting fixture of claim 5 wherein one half of the bulb is filled with the 420-490 nm blue phosphor and baked and the other side is filled with white phosphor and baked.

14. A method for creating balanced blue spectrum therapy lighting, the method comprising:

providing a light source; and

mixing blue light and white light having a range between approximately 90% 420-490 nm blue light and approximately 10% white light to approximately 10% 420-490 nm blue light and approximately 90% white light.

16. The method of claim 14 and further comprising:

providing an array of fluorescent bulbs or L.E.D.'"'"'s, the bulbs and L.E.D.'"'"'s containing blue light and white light.

17. The method of claim 16 and further comprising:

emitting blue light from one side of the bulb; and

emitting white light from the other side of the bulb.

18. The method of claim 16 and further comprising:

filling one half of the bulb with the 420-490 nm blue phosphor;

baking the blue phosphor;

filling the other half of the bulb with white phosphor; and

baking the white phosphor.

19. The method of claim 14 and further comprising:

adjusting the blue and white scotopic/photopic light levels thereby affecting melatonin levels.

20. The method of claim 19 and further comprising:

providing a switching mechanism selected from the group consisting of electronic, mechanical, and radio frequency activation switching.

21. The method of claim 14 and further comprising:

positioning at least one color sleeve over a light source for providing the blue light and white light levels.

22. The method of claim 21 wherein the color sleeves are adjustable.

23. The method of claim 14 and further comprising:

incorporating the blue light and white light levels into fiber optics, one fiber for blue light and one fiber for white light.

24. The method of claim 14 and further comprising:

combining the blue light and white light levels with an after-glow phosphor undercoat.

15. The method of 14 and further comprising:

mixing the blue light and white light with 50% 420-490 nm blue light and 50% white light.

25. The method of claim 25 and further comprising:

26. The method claim 25 wherein the scotopic phosphor blend comprises phosphors to give light primarily in the 400-620 nm range.
