Abstract: Road lighting is an important electrical load, and its low-carbon transformation is of great significance for achieving carbon peak and carbon neutrality. This article analyzes the influencing factors of carbon emissions from road lighting and proposes a calculation method for carbon emissions. Regarding the low-carbon transformation path of road lighting, the main measure to achieve carbon peak is the energy-saving transformation of lighting facilities. The key to deep low-carbon is to improve the energy efficiency standards of lighting fixtures, eliminate the waste of light in space and time, and calculate the overall energy consumption of road lighting in different scenarios. Aiming at carbon neutrality, from the perspectives of consuming clean energy, applying distributed photovoltaic power generation, and automatic load demand response, this paper proposes ways to integrate road lighting into new power systems in the future. In terms of the progress of low-carbon transformation, suggestions are proposed to accelerate energy-saving transformation based on factors such as technological maturity, policy implementation and standard matching, economic and social benefits, etc.
