What is the difference between the two standards under the comparison

As lighting fixtures, LED street lamps are widely used worldwide. The scale and quantity of lighting to support urban construction are increasing, and the energy consumption of urban lighting is also rising rapidly. How to meet the requirements of urban road lighting, traffic safety and smooth traffic on the premise of achieving scientific and reasonable power saving has become a common problem in all countries in the world. Domestic: The research on the energy-saving methods of LED street lamps is mainly reflected in the following two aspects: One is the use of high-quality and efficient new light sources to replace traditional light sources. For example, the 'Ten Cities and Ten Thousand Lights Program' launched by the Ministry of Science and Technology in 2009 is to make full use of LEDs. The huge energy-saving potential of the light source gradually replaces traditional light sources such as high-pressure sodium lamps, that is, the focus is on the design of LED light sources and lamps; on the other hand, the on-demand lighting is realized according to the requirements of road lighting at different times, such as the early adoption of half of the night after midnight. Light source in order to achieve power saving effect, recent research uses intelligent dimming technology and Internet of Things technology to realize automatic control of light source intensity at different times to achieve lighting energy saving. Both of these methods are designed for energy-saving road lighting from the level of project implementation, that is, the tactical level. The premise must meet the existing road lighting design standards, which means that the road lighting design standards have a vital impact on the level of lighting energy saving. . If the standard requirement is too high, it will affect the energy-saving level, if the standard requirement is too low, it will affect driving safety. Therefore, starting from the road lighting design standard itself, research on how to make the standard itself more conducive to energy saving under the premise of ensuring the safety of road lighting, has a deeper significance in the research of road lighting energy saving. The development of this research work can improve the road lighting Energy-saving research has risen from the tactical level to the strategic level, so as to achieve a greater degree of energy saving. International: The formulation and research of national road lighting design standards by countries generally refer to international road lighting design standards on the basis of the actual road traffic conditions. At present, there are two most authoritative standard systems in the world. One is the 'Road Illumination Recommendations for Motor Vehicles and Pedestrian Traffic' (115-1995) proposed by the International Commission on Illumination (CIE), which is adopted by most countries in the world ; North America: led street light 'road lighting' (RP-8-00) [8-9] proposed by the Illuminating Engineering Society of North America (Illuminating Engineering Society of North America, IESNA), it is mainly used in American countries. These two sets of standards are a comprehensive balance between the two factors of road safety and energy saving, and have been promoted on a large scale, but the similarities and differences between the two sets of standards are only carried out internationally. Some qualitative comparisons have been made. As for the main differences between the two types of standards in evaluation methods, lighting indicators, and energy-saving effects, there is still a lack of quantitative in-depth research. Therefore, an in-depth analysis of the quantitative differences in the evaluation indicators and calculation methods of the two standards and the related differences in lighting effects and energy consumption will have greater engineering guiding significance for the promotion of energy conservation and emission reduction from the strategic height of road lighting standards. And scientific value.
