Abstract

A fluid treatment device includes a pipe including an inlet, an outlet, an internal space through which a fluid moves and including a light source part disposed in the internal space and providing a light to the fluid. The light source part includes at least one light source unit having a substrate and a plurality of light sources disposed on the substrate and emitting the light. A ratio of a first distance between two light sources adjacent to each other to a second distance between each light source and an inner circumferential surface of the pipe is 1:1.25 or less when viewed in a longitudinal-section.

First claim

The invention claimed is:

1. A fluid treatment device comprising:
a pipe comprising a main body having an inner surface and an outer surface and extending in a longitudinal direction;
an inlet and an outlet spaced apart from the inlet in the longitudinal direction, and
an internal space through which a fluid moves; and
a light source part disposed in the internal space of the main body and extending along the longitudinal direction, the light source part comprising at least one light source unit including a substrate and a plurality of light sources disposed on the substrate and emitting the light, thereby providing the light to the fluid,
wherein the plurality of light sources is disposed to be spaced apart along the longitudinal direction such that a ratio of a first distance between two light sources adjacent to each other to a second distance from each light source to the inner surface of the main body is 1:1.25 or less,
wherein the second distance varies depending on the first distance and the first distance is measured in the longitudinal direction and the second distance is measured in a direction not in parallel with the longitudinal direction.

2. The fluid treatment device of claim 1 , wherein the ratio of the first distance to the second distance is 1:0.8 to 1:1.25.

3. The fluid treatment device of claim 1 , wherein the second distance is set from a center of the pipe to a point on the inner surface of the main body where an amount of light between the two light sources reaching the point is equal to or greater than about 70% of an amount of light output from the light source.

4. The fluid treatment device of claim 3 , wherein the first distance is set within a range that an amount of the light reaching an intermediate point between vertical points of the two light sources in the normal line direction of each light source, is equal to or greater than about 70%, or about 80% of the amount of the light.

5. The fluid treatment device of claim 3 , wherein a cross-section of the light source part includes shape of a regular n-polygon and each light source unit is disposed on each side of the regular n-polygon.

6. The fluid treatment device of claim 5 , wherein the cross-section of the light source part includes a triangular shape.

7. The fluid treatment device of claim 5 , wherein the pipe is configured to have a radius at a point where a ratio of an amount of light in a normal line direction of each light source unit to an amount of light on a line connecting a vertex of the regular n-polygon and a center of the regular n-polygon is about 70% or more.

8. The fluid treatment device of claim 5 , wherein the radius of the pipe is determined such that about 70% or more of light substantially uniformly reaches the inner surface of the main body and the radius of the pipe is 10 mm or greater.

9. The fluid treatment device of claim 5 , wherein the first distance is within a range from about 15 mm to about 30 mm.

10. The fluid treatment device of claim 5 , wherein the light source unit further comprises a transparent protective pipe that houses the substrate and the light source.

11. The fluid treatment device of claim 10 , wherein the light source unit further comprises a base that encapsulates both sides of the protective pipe.

12. The fluid treatment device of claim 5 , wherein the light source has an orientation angle from about 110 degrees to about 150 degrees.

13. A fluid treatment system, comprising:
a pipe comprising an inlet and an outlet and comprising an internal space through which a fluid moves, the pipe extending in a longitudinal direction; and
a light source part disposed adjacent to the pipe and providing a light to the fluid, the light source part comprising first light source units and second light source units, which face each other, with the pipe interposed therebetween, each of the first and the second light source units comprising a substrate and a plurality of light sources disposed on the substrate,
wherein a ratio of a distance between two light sources adjacent to each other in the longitudinal direction to a distance between two light sources facing each other in a direction perpendicular to the longitudinal direction with the pipe interposed therebetween is 1: 2.5 or less.

14. A fluid treatment system, comprising:
a main body having cylindrical shape extending in a longitudinal direction and having an inner surface, an outer surface, and an internal space through which a fluid moves; and
a light source part positioned inside or outside of the main body within a predetermined distance that light from the light source part reaches the fluid for treatment;
wherein the light source part comprises at least one light source unit including:
a substrate; and
a plurality of light sources disposed on the substrate; and
positioning and configuration of the plurality of light sources and the substrate differ based on the positioning of the light source part being inside of the main body or outside of the main body;

wherein the plurality of light sources is disposed to be spaced apart along the longitudinal direction such that a ratio of a first distance between two light sources adjacent to each other to a second distance from each light source to the inner surface of the main body is 1:1.25 or less; and
wherein the second distance varies depending on the first distance and the first distance is measured in the longitudinal direction and the second distance is measured in a direction not in parallel with the longitudinal direction.

15. The fluid treatment system of claim 14 , wherein the main body further comprises an inlet and an outlet, and
the inlet, the outlet, or both are arranged to be inclined to or perpendicular to the longitudinal direction of the main body.

16. The fluid treatment system of claim 15 , wherein the inlet and the outlet are arranged on the same side of the main body.

17. The fluid treatment system of claim 14 , wherein the fluid is a water.

18. The fluid treatment system of claim 14 , wherein the light source part emits the light in an ultraviolet light wavelength band.

19. The fluid treatment system of claim 18 , wherein the light source part emits the light in a sterilization wavelength band.

20. The fluid treatment system of claim 14 , wherein
the main body is a transparent pipe; and
the light source part disposed outside of and adjacent to the pipe and providing light to the fluid that flows the internal space of the pipe;
wherein a ratio of a first distance between two light sources adjacent to each other to a second distance from each light source to the inner surface of the pipe is 1:1.25 or less.
