LED street lamp light source and light pole, different road

In EMC project general government or manufacturer will be mentioned in the commercial negotiations with the government to the implementation of the test section, then test sections have what request?How we can well implement a qualified application of local authorities and satisfying?We discuss here.
First test section of appropriate choice in the spacing of lamps and lanterns, height, cantilever, elevation and the consistency of the light source is representative of typical sections.
1, spacing
Street lamp spacing as small as possible is preferred, the preferred distance is not more than 40 meters, had better choose in 35 meters away from the road.The gb CJJ45-2006 city road lighting design standard "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 cantilever length of lamps and lanterns should 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 (15 meters) to be beautiful, the road smooth wide.
3, light pole height

Light pole height preferred best 8 to 10 m, second is not more than 12 meters (high lever directly affect the injection Angle, light affect the intensity of illumination evenness), lamps and lanterns of cantilever hole with diameter of 60 mm is preferred.

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) as a main roads
1, must have a light type lamps and lanterns
2, according to the road lamp pole distribution as above
(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) the bilateral symmetry of cloth lamp: stem more than 9 meters high, 27 meters or less light pole spacing, the state and the test section to ask.
(2) of the road as a road
1, can be used or half light type lamps (such as the sectional type street light light unchanged with the above conditions)
Type 2, if use half light lamps according to the road lamp pole distribution as above
(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) the bilateral symmetry of cloth lamp: 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 Short or Medium (add, you may refer to aspects of light distribution I log in discussion of lamps and lanterns 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 ~ 0.25 choose Type , less than or equal to 0.25 the following selection Type , and cast light length is to stem from the width of the technology choice.)
