2 / 3 page CS120 Barcelona Tunnel Comes to Light Case Study 20160224 ©2016 Lumileds Holding B.V. All rights reserved. 2 Results and Benefits The greatest benefit to the lighting upgrade is significantly improved visibility and therefore, driver safety. The high color rendering (70) and cooler color temperature (4000K) LED light provides far superior visibility, allowing drivers to see “real” colors within the tunnel. In contrast, the old low pressure sodium lamps (2000K, 20 CRI) caused everything to look yellow and only provided one brightness level. The T-Max configuration and layout is modeled to provide optimal visibility along the Túnel de la Vila Olímpica Barcelona. “We partnered with Lumileds to provide luminaires that deliver exceptional output, use 40% less energy, and will last up to 25 years.” — Eduardo Serna Carandini Many tunnels throughout Europe feature centerline tunnel lighting. Unfortunately, when maintenance is required, both lanes of traffic must be shut down. With the side- based illumination, one lane of the Túnel de la Vila Olímpica Barcelona can be kept open at all times. Finally, the luminaire and LEDs deliver high reliability with rated lifetime of 100,000 hours (25 years). If maintenance of the driver is required in that period, it is performed separately from the light module. The upgrade has reduced the lighting electricity cost by 40%. Now that one tunnel has been upgraded to T-Max LED lighting with LUXEON M LEDs, Barcelona is receiving positive feedback from drivers. Solution With multiple years of experience in tunnel lighting, Carandini brought a custom design to the tunnel. Working with Lumileds and choosing the LUXEON M LED for its consistency of light output, high reliability and ultrahigh efficacy, the Carandini T-Max fixture provides 10,000 lm of light inside el Túnel de la Vila Olímpica. The T-Max has 11 different optical configurations to meet a variety of needs including lighting from one side. At the entrance and exit of this 1.5 km (1 mile) tunnel, stacked fixtures are used to provide 40,000 lm output. The luminaires utilize 4000K color temperature at a color rendering index of 70. The luminaires are evenly spaced for maximum uniformity. “Safety drives the design in tunnel lighting. We can drastically improve safety today by precisely modeling conditions and providing the exceptional light quality of LED lighting. — Francesc Palma Carandini The T-Max luminaire is a completely sealed unit with separate driver system that can be mounted together or separate from the light module. In this tunnel, the light module is mounted 30 cm above the drivers, allowing improved heat dissipation from the luminaire. Because the LEDs and other electronics are fully protected in a sealed, IP66 rated housing, the fixtures and drivers can be high-pressure spray washed as needed. The Carandini T-Max fixtures uses LUXEON M for its consistency of light output, high reliability and ultrahigh efficacy. |
