Lighting device
First Claim
1. A lighting device, comprising:
- a substantially cylindrical tube extending between an interior of a building and an exterior of the building, the tube having a first opening at a first end of the tube configured to receive light from the exterior and a second opening at a second end of the tube configured to emit light into the interior;
a reflective surface disposed on an interior surface of the tube;
a supplemental light source coupled to the tube and configured to illuminate the interior of the building; and
a plurality of projections disposed proximate the second end and extending inwardly, the projections configured to at least partially support a diffuser.

Abstract
A lighting device includes a substantially cylindrical tube defining an interior and an exterior, and a longitudinal axis extending between a first end and a second end. The first end of the tube defines a substantially cylindrical opening disposed in a plane at a first angle that is substantially perpendicular to the longitudinal axis, and the second end of the tube defines a substantially elliptical opening disposed in a plane at a second angle that is substantially non-perpendicular to the longitudinal axis. A reflective surface is provided on the interior of the tube, and a substantially cylindrical flashing is provided about the exterior of the tube. A substantially transparent dome is coupled to the tube proximate the first end, and a diffuser is coupled to the tube proximate the second end.

11. A lighting system, comprising:
-
a tube having a first end and a second end, the first end of the tube configured to receive light from a light source external to a building, and the second end of the tube configured to emit the light to an interior of the building; and a reflective surface disposed on the interior of the tube; and a supplemental light source located remotely from the tube, the supplemental light source including a transceiver configured to receive a wireless signal for controlling the supplemental light source in response to data acquired by a light sensor configured to measure a light level of the interior of the building. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of using a lighting device, comprising:
-
providing a tube defining an interior with a reflective surface and an exterior, and a longitudinal axis extending between a first end and a second end, the first end of the tube configured to receive light from a light source, and the second end of the tube configured to transmit the light to an interior of a building; providing a supplemental light source positioned to illuminate a portion of the interior of the building, wherein the supplemental light source comprises at least one LED included in the lighting device; measuring a light level in the interior of the building; and controlling the light output of the supplemental light source based on the measured light level in the interior of the building. - View Dependent Claims (18)
