Urban Park Road Lighting Research

Early human activities at night, just the day labor preparation with continuance, along with the increase in the level of productivity, and rapid urbanization process, urban night landscape becomes rich and colorful, human activities become frequent at night. The urban park is the highlights of the city night. How to make the park illumination design more humane, more in line with people recreation activity, make people feel comfortable and pleasant is become an important issue. Among them, the park road illumination design, is the miniature of lighting function and aesthetic requirements, which reflects the designer to the park overall assurance, shows the function of the charm of park in the night.This article study on Wenjiang park road lighting status field measurement and questionnaire investigation, this paper analyze the Wenjiang park road lighting and the characteristics of the visitors feel, with computer simulation technology, put forward Wenjiang park road lighting facilities spacing and illuminance new design scheme, for the city park road lighting facilities spacing from science design provide references.(1) Through observation, a preliminary understanding of Wenjiang park night use situation, compared with no.136-2000CIE technical report publication the city of different types of road lighting level, dividing Wenjiang park road lighting levels, and making the measurement standards for Wenjiang park road lighting:The main road is equivalent to CIE road lighting level P3, horizontal illuminance value not less than7.51x, minimum illumination value not less than1.51x, semi-cylindrical illumination is not less than1.51x; Minor road is equivalent to CIE road lighting level P4/P5, horizontal illuminance value not less than5/31x, minimum illumination value not less than1/0.61x, semi cylindrical illuminance not less than1/0.751x; Branch corresponds to CIE road lighting level P6, horizontal illuminance value not less than1.51x, minimum illumination value not less than0.21x, semi-cylindrical illumination is not less than0.51x; The illumination uniformity of the main road, minor road and branch should be maintained greater than or equal to0.2.(Note:"/" for high value on the left, the right side is low value.) (2) Carry on the questionnaire survey to the Wenjiang park visitors, and use the TES1339model illuminance meter, measuring tape, digital cameras and other tools to measure and record the Wenjiang park’s each grade section of the horizontal illuminance, vertical illumination, luminaire spacing and lighting layout method. According to the Wenjiang park road lighting the measured and questionnaire investigation results show that: There are large differences in field tests and questionnaires, particularly the branch field measured values are good. It means road lighting levels are affected by the surrounding environment, other lighting effects and the field illuminance measurements can not be as the sole criterion of evaluation of the park road lighting quality, it requires a combination of the same questionnaire.(3) Use DIALux lighting software on the actual luminaire spacing modeling, control measurement standard to adjust the luminaire spacing, optimized design for Wenjiang park road lighting arrangement distance to meet the requirements of the WenJiang park road illumination, and conclude that the suitable for Wenjiang park road lighting facilities layout space of the scope for the park road lighting design reference. Repeated the calculation in the DIALux software to obtain the ideal range suitable for the Wenjiang park road luminaire spacing:The main road width3-4m, luminaire spacing range for15-22m; Minor road width1.5-2m, luminaire spacing range for12-18m; Branch width0.8-1.5m, luminaire spacing for10m.
