Total luminous flux: Σ: (5) where Σ - total luminous flux, lm; A - is the total area of the facade lighting, m; E - the desired illumination, lx; u - utilization factor. The number of required Spotlights: Ⅳ = type 1'o (6) where Ⅳ - the number required for Spotlights, and Taiwan; o - single-lamp luminous flux, lm. Pieces illumination calculation and the required number of results cast light in Table 1. Table 1 sketches the basic parameters of lighting pieces Xiaoxiang Road 3.5, 3.5.1 for example landscape lighting floodlight tree with 4 sets of each tree buried lamp, 150W high pressure mercury lamp as light source, symmetrical distribution curve, open angle of 15. (Figure 3a). Characterized by the use of buried high pressure mercury lamp light source for the lights, using light from the bottom up according to guarantee the full visual illumination of the leaves surface. High pressure mercury lamp as light color and poor color rarely used in flood lighting, is very suitable for plant lighting, the light greenish, green plants can make colorful, more often than not by the color metal halide lamp and green filter more natural and green metal halide lamps. 3.5.2 The flood lighting mast with four sets of cast light, are located in the far side of the door frame, in January 2004 Avenue of Li Qian Xiaoxiang Lighting Design 29 b in Figure 3 Schematic layout of lighting fixtures close vote light, the light source to 250W metal halide lamp, narrow beam asymmetric distribution curve (Figure 3b). Feature is used to set far, close the narrow beam metal halide lamps for light, adjust the lighting angle and set the opening angle of the door frame of white light at the same time, does not result from the door frame under the glare produced by the visitors. 3.5.3 Training of flood lighting used lamps for light and lamp combination buried, because sailing is the use of tempered glass, the use of \the asymmetric curve of the node buried lamp, metal halide lamp base made of 7Ow buried (Figure 3c). Feature is the base for sailing and the different materials, using different lighting methods, in order to achieve harmony and unity of effect. 3.6 Load Calculation and road lighting transformer choose to 0 ~ 1.6km street transformer set 1 set an example. Lamp transformer load including: a land crossing of the reserve load, 40kW; 1 个 traffic police booth load, 10kW; 4 a bus station load, 32kW; 1.6km street loading, 52kW; 1.6km landscape lighting load 54. 3kW; Total 188.3kW. By the transformer load rate of 85%, the selected lamps 1 set 315kVA transformer. 4 summarizes the new design effect and Xiang Xiao road put into operation, not only by the central leaders and provincial and city leaders praised, but also by the general public, in particular, a good traffic driver evaluation. Xiaoxiang Street in particular Xiaoxiang Road lighting, with very satisfactory design results. Through Lighting Design Xiaoxiang Boulevard summary, the following points can be drawn from the experience, for your reference. (1) Road lighting design, it is necessary to meet the illumination standards, but also to reach a certain brightness and brightness uniformity index. If a main road in the city road lighting design, to meet the three indicators: average intensity of 3O ~ 35lx, the average brightness of 2.0 ~ 2.5cd / m, the brightness uniformity of more than 0.5, the only way to not only street lighting to meet the functional requirements, but also save energy. (2) flood lighting design, illumination standards, as the surrounding environment to adjust brightness, high brightness of the surrounding environment, to a corresponding increase in illumination standards, on the contrary, can be reduced accordingly. (3) high pressure mercury lamp metal halide lamp according to results to be better than the tree. (4) flood lighting to be more color and shading Mercy. (5) During the trial according to the process, according to the specific circumstances of the scene lighting, the location and angle of the lighting to make appropriate adjustments.
