It can be seen that the standard specification does not impose the requirement of setting lighting facilities on the medium-short tunnel, and most tunnels in the second-level, third-level and fourth-level roads do not impose the requirement of setting lighting facilities; for a tunnel without a lighting facility, a self-luminous induction facility and a directional reflecting outline sign are specified in the specification, and a tunnel outline strip can be adopted as the induction facility to enhance the tunnel induction effect in the specification of JTG D81-2017 highway traffic safety facility design specification in the national traffic industry standard specification, but the specific form requirement of the tunnel outline strip is not specified. The existing application basically and directly adds a method for retro-reflecting by sticking a reflective film on a plate-type outline strip on a tunnel and using a car lamp, thereby improving the reflective and induced illumination capability of the tunnel. Only the outline belt with the light reflecting function is arranged, and the traffic of vehicles and pedestrians without lamplight has great potential safety hazard. The tunnel profile strip type and the function are single in product function in the current practical application, the traffic flow of a plurality of tunnels is large, the traffic safety pressure is high, the demand of people along the line on tunnel induced illumination is also high, if the conventional lamp is simply adopted to add tunnel illumination equipment, the construction cost and later-stage electricity charge management unit are difficult to bear, and the contradiction between illumination energy conservation and traffic safety is prominent.
Currently, some attempts to enhance the light reflecting and illumination inducing capabilities of tunnels are made with tunnel profiles. As in the Chinese patent: a tunnel lighting warning system CN 106168357A discloses that vehicle light is reflected by a reflector with a V-shaped structure, and a light-emitting device is arranged to improve the brightness in a tunnel. Because the LED lamp of the device is arranged and wrapped in the shell, and the outer surface of the shell is coated with the energy storage luminous layer, the lighting effect is poor. Chinese patent: a reflecting ring CN209431334U for tunnel lighting features that a light source is embedded in the reflecting plates at both sides of a W-shaped reflecting ring, so it has no emergency light-emitting function and is large in size, complex in structure and poor in economic index.
