Light directing element
First Claim
Patent Images
1. A light directing element comprising:
- an elongated body having a first end, a second end and an exterior surface, the elongated body being transparent or translucent to permit transmission of light axially and radially therethrough;
a light emitter disposed at the first end of the elongated body;
a diffuser including at least one reflective element disposed within the elongated body, wherein the diffuser is configured to redirect axially emitted light from the light emitter radially towards the exterior surface and wherein the diffuser expands in cross-section towards the second end;
a first end cap disposed at, and configured to surround, the first end of the elongated body; and
a second end cap disposed at, and configured to surround, the second end of the elongated body;
wherein the first end cap and the second end cap support the elongated body a distance from an adjacent structure.

7. A light directing element comprising:
-
a transparent or translucent body having a first end, a second end and an exterior surface; and a diffuser disposed within the transparent or translucent body and expanding in cross-section towards the second end, wherein; the diffuser comprises at least one reflective element configured to redirect light axially transmitted from the first end radially towards the exterior surface; at least a portion of the light comprises disinfecting light with a wavelength in a range of 380 to 420 nanometers; and the diffuser is configured to redirect the at least the portion of the light toward the exterior surface with a substantially uniform irradiance at least 0.02 milliWatts per square centimeter (mW/cm2) across an area of the exterior surface. - View Dependent Claims (8, 9, 10, 11, 12, 13)
