路灯是城市照明的重要组成部分，传统的路灯常采用高压钠灯，高压钠灯整体上光效低的缺点造成了能源的巨大浪费，因此，开发新型高效、节能、寿命长、显色指数高、环保的路灯对城市照明节能具有十分重要的意义。LED路灯具有环保无、耗电少、光效高、寿命长等特点，因此，LED路灯将成为节能改造的最佳选择。光源采用模组化设计方案，实现了地面照度与功率的最佳匹配，通过增减光源数量，来满足不同的路面宽度和照度要求，达到了既满足城市的照明要求又不浪费电能的目的。

Street lamp is an important component of urban lighting. The traditional street lamps often use high pressure sodium lamp. The disadvantages of high pressure sodium lamp on the whole make it a waste of energy, Therefore, the development of new, efficient, energy-saving, long life, high color rendering index, environmental protection streetlights is of great significance to the city lighting energy-saving. LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction. The light source adopts modular design, to achieve the best matching ground illumination and power, by increasing or decreasing the number of light sources, to meet the different pavement width and illumination requirements, to meet the lighting requirements of the city and not to waste energy purposes.
