Abstract
Embodiments of the invention include an elongate chamber. A UV source includes a semiconductor device, the semiconductor device including an active layer disposed between an n-type region and a p-type region. The active layer emits radiation having a peak wavelength in a UV range. The semiconductor device is positioned on a wall of the elongate chamber. An inner surface of the elongate chamber is reflective.
Claims18
A water disinfection vessel comprising:
- an outer shell;
- a first ultraviolet (UV) light emitting diode (LED) within the outer shell;
- a transparent liner within the outer shell for containing water, the water having a first index of refraction,
- the liner having an inner wall contacting the water, the liner being formed of a material having a second index of refraction less than the first index of refraction, such that light from the first UV LED is reflected off a water-liner interface by TIR when the light is incident on the interface at less than the critical angle,
- the liner having an outer wall that reflects light that passes through the inner wall;
- and
- a power source controlled to energize the first UV LED for an amount of time to at least partially disinfect the water.
