Multi-spectral uniform light source
View Patent ↗A multi-spectral uniform light source provides a single light source for a variety of applications. The gas or gases inside the light source may be exchanged for another gas or gases depending on the desired application and need for a particular wavelength of emitted light.
1. A method of modulating a light source, the method comprising:
providing a hollow tube having a first end with a first endcap and a second end with a second endcap, an inlet valve and a first electrode associated with the first end and an outlet valve and a second electrode associated with the second end;
opening the inlet and outlet valves to provide for a simultaneous modification of gases between said first electrode and said second electrode;
flowing a portion of a first gas from between said first and second electrodes out of the light source through the outlet valve, and simultaneously flowing a second gas through the inlet valve into between said first and second electrodes, said first gas being different from said second gas;
providing power to the first and second electrodes during the flowing of the first and second gases to modulate the light source; and
closing the inlet and outlet valves.
2. The method of claim 1 , wherein the first gas is selected from the group consisting of: inert gases, krypton, argon, neon, xenon, helium, mercury, neon/helium mixture, neon/argon mixture, oxygen, hydrogen, ditrium, and nitrogen.
3. The method of claim 1 , wherein the second gas is selected from the group consisting of: inert gases, krypton, argon, neon, xenon, helium, mercury, neon/helium mixture, neon/argon mixture, oxygen, hydrogen, ditrium, and nitrogen.
4. The method of claim 1 , wherein the first gas is selected from the group consisting of: inert gases, krypton, argon, neon, xenon, helium, mercury, neon/helium mixture, neon/argon mixture, oxygen, hydrogen, ditrium, and nitrogen; and the second gas is selected from the group consisting of: inert gases, krypton, argon, neon, xenon, helium, mercury, neon/helium mixture, neon/argon mixture, oxygen, hydrogen, ditrium, and nitrogen.
5. The method of claim 1 , wherein the inlet and outlet valves include seals to prevent gas from leaking past or through the valves from the tube.
6. The method of claim 1 , wherein the hollow tube comprises a straight hollow tube shape.
7. The method of claim 1 , wherein the hollow tube comprises a serpentine shaped hollow tube.
8. claim 1 The method of claim 1 , wherein the light source comprises a lamp array of serially connected light sources.
9. The method of claim 1 , wherein the hollow tube comprises a rectangular planar shaped hollow tube.
10. The method of claim 1 , wherein the hollow tube comprises a spiral shaped hollow tube.
11. The method of claim 1 , wherein the hollow tube comprises a ring shaped hollow tube.
12. The method of claim 1 , wherein the hollow tube comprises a channel shaped hollow tube.
