Tunnel lighting arrangement
? relative: relative and staggered arrangement is usually that the fixture is installed at one place between the wall and the axes zenith, rather than mounted on the side, the reason is to provide a good visual environment, so that the average brightness within the range of the bottom of the tunnel walls to 2m is not less than the average brightness of the road surface.
? middle: intermediate arrangement is that the lighting is installed at the zenith axis, but the maintenance is more difficult, it will affect traffic, so generally do not take this approach. http://www.amazines.com/
