Description

A kind of city illumination system

Technical field

The utility model is related to a kind of lighting system, specifically a kind of city illumination system.

Background technology

Illumination pipelining mode is that light conduits covers PVC-U pipe buried-pipe layings at present, and buried depth is 0.7 meter.Pipeline applies If position is generally in two kinds of situation, the first situation is that shade tree is not afforested in road driveway both sides, illuminates pipeline at this time and buries If position is away from the inside of carriageway kerb 0.5 meter.The second situation, which is road driveway both sides, greening shade tree, in order to The required space of evacuation plantation shade tree, it is away from the inside of carriageway kerb 1.3 meters to illuminate pipeline burial place at this time.When When to illuminate pipelining position be the second situation, at this time road piping width of corridor compared with the first situation when increase 0.8 meter. This also means that the red line range of road will increase by 0.8 meter, when boundary lines of roads space is limited, illuminates the laying position of pipeline It is more apparent with the plantation contradiction of shade tree.Ensure that the plantation of shade tree, illumination pipeline just need to concede enough plantation skies Between.
