LD-DG photoelectric signs are used to guide drivers and passengers in highway tunnels to the location of emergency telephone alarms and fire-fighting facilities in the event of an accident.
The signs mark the location of the emergency parking strip and guide pedestrians/vehicles in the accident tunnel to enter the tunnel where no accident has occurred through the pedestrian and vehicle cross tunnels.
All signs are self-luminous signs, visible on both sides, and the internal lighting fixtures are LEDs with a total power of no more than 10w. The color, installation height and location of each sign are in line with the national industry standard JTG/TD71-2004 "Highway Tunnel Traffic Engineering Design Specifications".
The size of the cross tunnel and emergency parking strip signs is 50cmX80cm (width x height), the size of the emergency telephone and fire equipment signs is 25cmx40cm (width x height), and the size of the emergency evacuation sign is 40cmX25cm (width x height).
