Need to design

Whether the energy consumption of urban road lighting is reasonable, is mainly to see whether the design is reasonable. A few years ago, many cities in the urban lighting in the phenomenon of blind comparisons, think that the brighter the better, far more than the scope of the relevant national standards. For example, in "urban road lighting design standards" CJJ45 - 2006 in the I grade road surface average illumination value should be in the 20 - 30lx is appropriate, but to understand that many of the road pavement average illumination value is maintained at 70 - 90lx, and even more than the phenomenon of 100lx. The average illumination value of the standard, making the evaluation of the lighting energy efficiency of the "power density value" index exceeded. If we adhere to the standard 30lx operation, then the power of more than 50%.

Therefore, at the same time, we should also pay attention to another tendency to prevent the reduction of standards, the loss of functional lighting significance, and can not meet people's night travel, sanitation operations, students sooner or later study traffic safety:

Scientific and reasonable design is a comprehensive concept, it contains many aspects of the choice, in a number of energy saving measures should be designed to compare, comprehensive, from the optimal solution.
