TUNNEL LIGHT CONTROL SYSTEM

摘要

The present invention relates to a tunnel light control system, including lighting units which are installed along a length direction of a tunnel separately from each other in the tunnel and illuminate the inside of the tunnel, and a lighting control part for controlling driving of the lighting units. At least one lighting lamp is installed in the lighting unit. The lighting control part includes a first mode of turning on the whole lighting lamps as to the number of lighting the lamps as to the lighting units, and a second mode of turning on the lamps in smaller number than the total number of the lamps, and performs the first mode and the second mode selectively according to luminance change in the outside of the tunnel or an established mode adjustment time. The lighting control part controls to drive the lamp according to a circulation cycle established according to a lighting lamp group grouped to drive the lamp selectively which is driven on during the second mode, so that the lamp driven in a previous second mode is turned off whenever the second mode is performed. By this tunnel light control system, driving time difference of the lamp can be suppressed by controlling the lamps sequentially according to the established circulation cycle as to the lamps, a part of which is driven when the luminance in the tunnel is changed. Thus, it is possible to change the lamps in a lump when usage lifetime ends, and it is possible to suppress unnecessary wasting of resources.
