Abstract

Embodiments of the present invention provide a water treatment device that can treat water at its point of use. For example, the water treatment device may be positioned at or near a faucet outlet, so that water can be treated immediately before it leaves the faucet. The water treatment device may be a water treatment reactor with a plurality of UV LEDs positioned between a shield and a heat sink component.

First claim

What is claimed is:

1. A water treatment device, comprising:
a treatment chamber;
a first set of ultraviolet light emitting diodes positioned at one end of the treatment chamber, and a second set of ultraviolet light emitting diodes positioned at an opposite end of the treatment chamber;
each of the first and second sets of ultraviolet light emitting diodes being supported by first and second end caps;
the first end cap comprising an inlet for receiving water to be treated, the second end cap comprising an outlet for exit of treated water;
each of the end caps further supporting a shield secured in front of the ultraviolet light emitting diodes, the shield allowing UV light to pass through, and a heat sink secured behind the ultraviolet light emitting diodes.

2. The water treatment device of claim 1 , wherein each of the first and second end caps comprises a support member and a rear cap.

3. The water treatment device of claim 1 , wherein the treatment chamber comprises a mirrored or shiny reflective surface along its interior.

4. The water treatment device of claim 1 , wherein the treatment chamber has a first connecting portion and wherein the end caps each have a second connecting portion.

5. The water treatment device of claim 4 , wherein one of the first or second connecting portion comprises a threaded portion and wherein the other of the first or second connection portions comprises a thread receiving portion.

6. The water treatment device of claim 1 , wherein the end caps form a groove for supporting the shield.

7. The water treatment device of claim 6 , wherein the end cap comprises (i) a first portion containing a first portion of a groove on its rear face and (ii) a rear portion comprising a second portion of a groove on its front face, wherein when the first portion and the rear portion are secured to one another, the first and second portions of a groove collectively form a groove for supporting the shield.

8. The water treatment device of claim 1 , further comprising at least one sealing element between each of the end caps and the treatment chamber.

9. The water treatment device of claim 1 , further comprising at least one sealing element between each of the end caps and the shield.

10. The water treatment device of claim 1 , wherein the first and second sets of ultraviolet light emitting diodes positioned are mounted on first and second printed circuit boards.

11. The water treatment device of claim 10 , further comprising a thermal paste between the heat sink and the printed circuit boards.

12. The water treatment device of claim 1 , wherein the first and second sets of ultraviolet light emitting diodes comprise organic light emitting diodes.
