Scope

Scope: This document stipulates the basic requirements, maintenance cycles, general provisions, maintenance records, safety operations, evaluation and assessment of maintenance, and follow-up services for the maintenance of green lighting in urban roads. This document applies to the maintenance of green lighting facilities (tunnels and bridges) with voltages of 10kV and below in urban roads that have been put into use after completion and acceptance. This document does not apply to special repairs aimed at improving the lighting rate and integrity of facilities. Main technical content: 5.1 When replacing spare parts, it is recommended to use products with the same model and specifications as the original ones or alternative products with better performance. The performance and technical parameters of the spare parts should not be reduced, and the safety performance of urban lighting facilities should not be affected. 5.2 Any changes to the technical parameters of key spare parts shall be subject to the written consent of the urban lighting regulatory authorities and, if necessary, technical demonstrations. 5.3 On the premise of ensuring lighting effect and quality, it is encouraged to adopt "new technologies, new processes, new materials, and new products" in the maintenance of urban lighting facilities. 5.4 The replacement parts selected during maintenance must comply with the relevant mandatory standards of the state and the industry. 5.5 For the scrapping of lighting facilities, the relevant procedures for asset disposal shall be complied with. 5.6 There should be no obvious color difference before and after the replacement of lamps (light sources). The luminous efficiency and color rendering index of the replaced lamps should not be lower than that of the original lamps. 5.7 Unless otherwise specified, the power of the replaced lamps should not be greater than that of the original lamps. 5.8 When replacing components such as capacitors, bal
