Shakespeare Lighting Design LLC 1806 E. Thornton Dr. Bloomington, IN 47401 812-320-2796 B. Context: 1. The revitalized park adjacent to the South Face of the Jefferson bridge, the river walkways on the east, and the upstream pedestrian bridge offer the best views of the south bridge face. This is the quiet side of the bridge where the flowing river is relatively noiseless and both sides of the river are green scape. River Lights currently peeks through the arches of the bridge, and its south face is a dark silhouette. C. Concept: 1. Our lighting concept focuses on the three main southside chalices (piers) connected by points of light along the base of the pedestrian rail, similar to those of the northside. As the chalices are on the upstream side, where lighting from below would be easily swept away by large floating tree trunks and debris, our approach is to light them from above. Due to a limited budget, I have focused on these main central features. This lighting of the chalices is accomplished by a series of linear color changing luminaires, mounted on the curved rims of the upper chalices, a few inches below the 1’-3” wide coping which extends beyond the pedestrian railing. These unique “wall-washer” luminaires have a small 4.25” wide and 2.25” height profile and are 2’, 3’ or 4’ long, mounted on 18” outriggers, secured into the concrete face. With a slight upward tilt of about 20 degrees, this setback distance enables the light to wash down the chalice face with reasonable uniformity. The color and intensity of each foot of each light can be independently controlled enabling color to smoothly wrap around each chalice. Typically, the new color begins at the chalice upstream center and flows to either side, like the water breaking around the pier below. Related colors follow, creating a beautiful visual flow. Points of light, mimicking the north side, compliment the chalice lighting and visually anchor the bridge span at night. Budgetary limits necessitate an effective, but lower priced direct view luminaire on the South Side. Lighting Control is extended from the north side River Lights control and communication system, adding an additional controller and linking it, mostly through existing low voltage conduit, to the Southside of the bridge. The overall visual lighting effect can be seen in an attached “snapshot” concept image. D. Details 1. Typical low profile IP66 linear RGB grazing luminaires produced hot spots at the top of the Chalices and dim gaps between luminaires, which are unacceptable.
