Photo a) At Bayer’s branch office in Vienna, Austria, an innovative facade lighting was achieved by replacing the metal halide lamps used previously with LED spotlights developed by LEDworx GmbH (photo b). The purpose of switching to LEDs was to improve the lighting situation in front of the building and create safer walkways with fewer accidents for its employees and other pedestrians. As photo a) shows, the new LED luminaires display significant advantages in terms of brightness on the walkway combined with uniform illumination of the entire area. And most importantly, these advantages are achieved with a 25 percent lower connected load. Bayer MaterialScience supports this technology by developing special grades of its transparent polycarbonate Makrolon®. Lenses made from this material ensure that the light is concentrated and directed efficiently. Home
