Courtyard lights are mainly suitable for roads, squares and parks in the community, such as roads, squares and parks. The garden light manufacturer Jindou Lighting details the principles and layout of the garden lights. Garden lights can be divided into two types: 1. Diffuse reflection, no mask This kind of light is scattered everywhere, so most use 150W high pressure sodium lamp (the metal halide lamp is too dazzling). The height can be between 3.5~4.5. Generally, the lamp poles are 3.5 and 4.5 meters. The best distance between the lights is 18-20 meters, not too close. 2. Indirect, there is a mask, this kind of light is not scattered everywhere, so sodium lamp and metal halide lamp can be used with a 150W spacing and it is OK at about 16 meters. The garden lamp that can be expanded is a 45W spiral tube energy-saving lamp, luminous flux It can reach more than 2300lm, the color temperature is generally 2700K, the lamp height is 3.5m, the color rendering index can basically reach Rau003d80, the layout of the main road is 18m, and the layout of the secondary road is 20m. In addition, one lamp is arranged at the intersection of the entrance of each unit in the residential area and the main fire lane for separate control of night lighting. On the road, it is controlled in two ways by using the interval jumper method, and the lights are turned off in the second half of the night to save energy. According to engineering practice, the dark band between the two lamps of the courtyard lamp is just eliminated, that is to say, the arrangement spacing is basically appropriate. If there is a change in the height of the light pole, the arrangement spacing of the garden lights will be adjusted accordingly. Therefore, the factors that affect the installation spacing of courtyard lights are roughly as follows: 1, the width of the installation road; 2, road lighting requirements; 3, the height of the courtyard lamp and the power of the courtyard light source So what is the installation spacing of the courtyard lights in different situations? [Garden Lights] produced by Jindou Lighting. Based on years of experience in the design and installation of outdoor garden lights, Jindou Lighting organizes the following specifications for the height and road width of conventional garden lights: road width (M) garden light height (M) light source power (W) garden light installation spacing (M)3- 52.5-3.5 Energy-saving lamps 13W-45WLED lamps 5W-18W metal halide lamps, high-pressure sodium lamps 35W-70W5-156-93.5-5 energy-saving lamps 45W-85WLED lamps 18W-40W metal halide lamps, high-pressure sodium lamps 35W-150W15-20
