road grade differences LED street lamp light source and how to choose the light pole

in the EMC project general authorities or the manufacturer in the commercial negotiations with the authorities mentioned in the city in the implementation of the test section, then test sections have what request? Well implement a qualified, how can we make test section of local authorities department right? We discuss here. First test sections should select in the spacing, height of lamps and lanterns, suspension thin, elevation and the consistency of the light source is representative of typical sections. 1, the distance between street lights were set as small as possible, the preferred spacing is not more than 40 meters, the best choice in 35 meters away from the road. The gb CJJ45 - 2006 city road lighting design scale street lamp spacing reference: sectional type lamps and lanterns light light pole height about 3 times of itself for spacing, choose a perfectly straight road, don't choose to bend or intersection. The installation height of the suspension of lamps and lanterns thin length shoulds not be more than a quarter, the elevation of lamps and lanterns should not be more than 15 °; 2, right road width to four lanes ( About 15 meters) To be beautiful, the road smooth wide. 3, light pole height light pole height 8 - preferred 10 meters, best time to choose no more than 12 m ( Rod directly affect the Angle of optical injection, high impact intensity of illumination evenness) Lamps and lanterns, cantilever hole with diameter of 60 mm ￠is preferred. Country road scale reference: the light distribution types of lamps and lanterns, the installing way and the installation height of lamps and lanterns, the relationship between spacing note: Weff effective for pavement width ( m) Need to pay attention to in the table above, here is the key. Due to countries have a street lamp light distribution specification, differences in test section will choose the lamps and lanterns of divided light distribution. Example: a road right 18 meters, green belts among four lanes 2 m, how to determine the path on the light pole and lamps and lanterns light distribution for a test section? Solution: ( A) Road as a main road 1, must adopt the light type 2 lamps and lanterns, according to the above the road light pole distribution of ( 1) Bilateral staggered cloth lamp: rod is 12 meters high above, light pole spacing 36 meters or less, to the state and the test section to request. （ 2) Bilateral symmetry cloth lamp: rod is 9 meters high above, light pole spacing 27 meters or less, to the state and the test section to request. （ 2) Road as a road 1, can use sectional type or half light lamp ( Such as the sectional type street light light unchanged with the above conditions) Type 2, if use half light lamps according to the above the road light pole distribution of ( 1) Bilateral staggered cloth lamp: 14 meters high, light pole spacing of 50 meters or less, to the state and the test section to request. （ 2) Bilateral symmetry cloth lamp: stem more than 11 meters high, light pole spacing 39 meters or less, to the state and the test section to request. Conclusion: if choose this section as the test sections, so it is best to use the LED section Type lamps and lanterns, light with light way is best for the Type Ⅱ Short or Medium ( Add, you may refer to aspects of light distribution I log in discussion of lamps and lanterns of light distribution and light distribution of basic formula is: high lever H present right W, they are the Type of business is equal to 1 choice between I light distribution, less than 1 to 0. Choose Type Ⅱ 25, less than or equal to 0. 25 the following selection Type Ⅲ, and cast light length technology choice is to stem from the width. ）
