Lighting pole design requirements.
Lighting pole design method.
Road lighting design should base on the characteristics of roads and places and lighting requirements, select the conventional lighting or high pole lighting.
The arrangement of conventional lighting fixtures can divide into five primary ways:
One-sided layout, two-sided staggered design, bilateral symmetrical layout, symmetrical interior layout, and horizontal suspension layout.
When using conventional lighting methods, it should be selected according to the road cross-section form, width, and lighting requirements, and should meet the following criteria:
When using high pole lighting, the lamp and its configuration, the installation position of the lamp pole, height, spacing.
The projection direction of the maximum light intensity of the lamp should meet the following requirements:
According to different conditions, plane symmetry, radial symmetry, and asymmetry can select.
The high pole lights arranged on the wide roads and around the vast area should adopt the symmetrical plane configuration;
The three-dimensional crossed pole lights arranged inside the venue or with a compact lane layout should take a balanced radial configuration;
The asymmetrical shape should adopt for high-pole lamps that are arranged in multi-layer large-scale three-dimensional intersections or lanes.
The calculation should determine no matter what kind of lamp configuration method is adopted.
The ratio of lamp pole spacing to lamp pole height according to the luminosity parameters of the lamps and lanterns;
Lampposts must not be located in dangerous locations or in places that severely impede traffic during maintenance;
The maximal light projecting direction of the luminaire and the intersection angle of the perpendicular should not exceed 65°;
The pole lights in urban areas should coordinate with the environment under the premise of satisfying the lighting function requirements.
The cantilever length of the luminaire should not exceed 1/4 of the installation height, and the elevation angle of the luminaire should not exceed 15°;
The arrangement of lamps, installation height, and spacing, can be determined after calculation.
