Lighting a tunnel or subway, particularly long structures, requires quite different lighting design techniques to road lighting. A driver entering a long tunnel must maintain a visual scene of conditions ahead when moving from daylight into a tunnel. Much higher luminances are therefore needed for the first sections of a long tunnel to allow a driver’s eyes to adjust and to cancel the ‘black-hole’ effect at a tunnel entrance. Our lighting designs for tunnels, subways and underpasses alleviate the ‘black-hole’ effect and fully compliant to British Standard BS 5489-2 and other relevant codes of practice.Our subway and underpass lighting designs are lit to appropriate daytime and night-time lux levels and contribute greatly to a pedestrian’s safety and security.
