A DBLP(Double Blind Light Pipe) system has been introduced to improve the overall system efficiency of a LFLP(Linear Fresnel Light Pipe) daylighting system. The new design consists of Double Blind style with a cone shaped light transformer. The blinds are used to collect the sun’s altitude and azimuth movements throughout the day. The light transformer was designed to efficiently deliver the light within a 30 degree radial spread so the light pipe could total internally reflect the light. This system was designed to have two light transformers output into a single light pipe. The system provides useful direct daylight more than 10 meters into the building core. And it reduce energy for standard commercial building lighting by at least 25% of replaces electric lighting 75% of the time each day that the sun shine within six core hours. This allowed 24,000 to 30,000 lumens to be inputted into a single light pipe. The result of the scale model tests look encouraging and the efficiencies are three times higher than the previous LFLP system. |
