At the legislative hearing on the "Shenzhen City Lighting Management Measures (Draft for Comment)" held yesterday, the Urban Management Lighting Management Center revealed that there are about 240,000 energy-saving LED street lights in Shenzhen, and LED energy transformation, energy saving effect of more than 50 %.
Does the hearing mainly limit the scope of landscape lighting? Discuss how to scientifically and rationally define the scope and other issues. The Shenzhen Legal Affairs Office disclosed that it intends to adopt legislation to regulate and improve the construction and maintenance of urban road lighting, and to beautify the city through the “three simultaneous†requirements. The "Measures" clarify that the functional lighting facilities and the key regional landscape lighting facilities delineated by the main project and the urban lighting special plan shall meet the requirements of the urban lighting special planning, and shall be designed, constructed and put into use simultaneously with the main project. .
1. How to balance energy saving and lighting
Some people have suggested that energy conservation and lighting itself are contradictions that are difficult to reconcile. The same is true between landscape lighting and energy conservation. How to balance the contradiction between the two? Citizen Chen Jingliang mentioned that the current road lighting generally uses high-pressure sodium lamps, metal halide lamps and some LEDs. It is understood that high-pressure sodium lamps and metal halide lamps are relatively power-hungry, and the high-power light decay of LED street lamps is more serious.
Shenzhen City Management Bureau Lighting Environmental Management Center introduced that there are currently about 240,000 energy-saving LED street lights in Shenzhen, and the rest are high-pressure sodium lamps. In addition, the municipal competent department has formulated a special plan for urban lighting to better balance the contradictions between the two. For example, the urban lighting special plan should combine the urban natural geographical environment, humanities conditions, traffic safety requirements, according to the urban functional division, and put forward requirements for urban lighting construction management in different regions and different time periods. The energy-saving LED lamp has a power saving effect of more than 50% compared to the original lamp.
2. How to solve the problem of lamp trees?
Zheng Xiaojun, a citizen, suggested that when he walked on the road at night, he felt that the lights were very dark. When he looked up, he was blocked by trees. The question of the lights and trees, did the solution provide an effective solution?
“Shenzhen road lighting adopts intelligent monitoring. The daily switching lights are all based on the curve formed by sunrise and sunset time. The lighting time is different every day. The maximum lighting time in winter and summer is 1 hour and 15 minutes gap.†Shenzhen Urban Management Bureau Lighting Environmental Management Center introduced, Shenzhen street lighting design basis includes “urban road lighting design standardsâ€, Shenzhen local standards “LED road lighting engineering technical specifications†and “Shenzhen road lighting engineering construction†And the acceptance procedure, the streetlight design will be designed according to these standards, and the city and city management bureau will review the construction drawings of the streetlight project according to these standards.
Lunan, a citizen, hopes that there will be certain design specifications or standards for the sidewalk and greenway lighting in the legislation. For different road sections, the number of street lights, light intensity and appearance should be set according to the surrounding environment to better integrate with the surrounding environment. Shenzhen City Administration Bureau Lighting Environmental Management Center explained that in order to make urban lighting management work more standardized and supervision more in place, Shenzhen Urban Management Bureau has formulated relevant maintenance standards and regulatory assessment standards and officially issued.
