Chuck Harder from Bitro Group told us about his company's LightSymphony Addressable RGB System, which uses RGB "pucks" controlled by a DMX system to produce full animation effects. This system goes beyond the regular fade and color changing capabilities of some current RGB systems and helps the borders of the letters stand out. "We worked diligently to provide a sign that continues the tradition of being a historic landmark in downtown Chicago," Mike said. "Paying close attention to capture the spirit of the previous sign, this new display incorporates the latest and greatest in lighting technology." With the basic design concept in place, Landmark began fabricating a single letter panel for testing and approval from the Goodman Theatre. The panels consist of a 6 x 6-ft. 4-in. piece of 1-in.-thick clear acrylic with a routed groove around the perimeter in which we embedded red GE Tetra Contour LEDs to create a halo effect. We back-sprayed the back panel a burgundy color and mounted a 2-in. aluminum tube border to the peri- meter of the face. Finally, we used Matthews 15394 Red Ferrari to paint the acrylic panel backed with 3mm Alucobond. The letters mounted to the panels are 5 ft. tall x 5 in. deep fabricated aluminum. The perimeter of the letters has a 2.5-in. channel to house the addressable RGB pucks along with GE Tetra MAX High Output white LEDs. We covered the channel with 2247 white acrylic placed flush to the letter face. The insides of the letters have a recessed piece of ½-in. acrylic painted second surface that SIGNWEB.COM SIGNS OF THE TIMES 59http://www.SIGNWEB.COM
