1, the shadow between longitudinal street lamp lighting & throughout; :
because planning is not reasonable, the interval of lamp is too big or the light distribution curve of lamps and lanterns along the road longitudinal maximum intensity of illumination of the viewpoint is too small, lead to low between light and the light intensity of illumination. This road will be a bright one dark & throughout; , which bring great visual fatigue driving.
2, shadow between transverse street lamp & throughout; :
because planning is not reasonable, the height of the light pole, the elevation of lamps and lanterns, or lamps and lanterns along the path of light distribution curve of lateral maximum intensity of illumination viewpoint is too small, leading to the central part of illuminance is too low, it will also bring many inconvenience to traffic.
3, the shadow of intersection lighting & throughout; :
because intersections are very broad & throughout; Arrange equipment, normal street lamp, roots reach illumination requirements, in some intersection center illuminance is very low. Processing method can be further equipment additional light pole and lamps and lanterns, or half light, the Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 Illuminance level, its illuminance values should be straight sections 1. About 5 times, thus avoiding the driver for pavement illuminance suddenly fell and affected the visual, reduce traffic accidents.
