Title

Single-Axis Tracking Beam Sunlighting System

Abstract

A new approach to beam daylighting with an active tracking system is capable of illuminating a 1000 square foot area with no glare or localized overheating and with relatively uniform illumination over the course of most of the daylit hours in the day. For good performance at low solar elevation angles, a one-axis tracking system is employed, along with a patent-pending optical system to accommodate changes in solar elevation throughout the day. The design includes a glazed collection head on the roof, which redirects incident beam sunlight downward into a reflective light shaft through the ceiling below. A ceiling luminaire distributes this light flux across a diffusely-reflecting white ceiling and into the space below. This new technology is expected to move into production in mid-2006. Initially targeted for the Colorado new school construction market, additional sales are planned to school districts in other states and to additional commercial, industrial, and residential markets later. This paper presents the design philosophy and early performance measurement results.
