Multi-dimensional Light Source For Multi-storey Road Space Lighting Research

With the social and economic developing, many multi-dimensional roads join in the urban space transportation.Urban space is gradually changing with the multi-dimensional traffic lighting using. Today, multi-dimensional traffic is a mature urban infrastructure in city. Undergone a qualitative leap bid farewell to the backward lighting equipment in lighting equipment, Lighting system gradually focuses on the reliability, ease of maintenance and so on.Although our multi-dimensional traffic lighting has made great achievements, but there are still some problems to be solved, Such as the light source and lighting poor choice, poor tolerance lamps, unreasonable lighting, pole spacing properly, power consumption is relatively large, on the road intersection, curve and ramp lighting is not enough attention etc.people have higher requirements of outdoor lighting,combined with the world's energy, especially electricity tension, causing people to the conflict between requirements and increasing energy. In order to maximize the energy and create a good environment of outdoor lighting for people. Lighting design principle is that with the appropriate light and the right way to invest in the right place at the right time. The main task of road lighting is to improve transport efficiency and reducing traffic accidents, the relations are very important, The road lighting is one of the main part of outdoor, lighting energy consumption is vary larger. So, people should find the best golden point between lighting quality and energy consumption.Status for road lighting, to study road lighting following aspects in this thesis. First of all, the road is not only modern facade layer, and the plane partition, Writer does DIALux traffic simulation analysis for this multi-level and multi-dimensional regional status, proposing model road lighting road traffic problems and their solutions, summering up the determinants of the quality of road lighting in the quality. Second, multi-dimensional and multi-level traffic space, simply raising the level of illumination and brightness are not enough, homogeneous space would be too disoriented people, for people on the road lighting requirements, Lighting in the existing indicators, based on the brightness difference on the road lighting calculations established computational model similar to Kerchief's circuit. Proposing treatment in lighting technology, the different spatial planning in accordance with pre-lighting standards, not only need to pay attention to the brightness difference between the various functional areas, but also stressed the entrance and the core functional areas, weakening the transition zone. Finally, for multi-path space lighting design, combines special traffic topography of Chongqing, Lighting from Chongqing City, proposing some suggestions about the current situation of the road structure on specific lighting design.This thesis studied the road lighting, especially for multi-regional and multi-level lighting in-depth analysis, both in academic research and in the construction area, has great reference value.
