1, the 'shadow' between longitudinal street lamp lighting: due to the unreasonable design, light spacing is too big or the light distribution curve of lamps and lanterns along the road vertical illumination Angle is too small, lead to low between light and the light intensity of illumination. This road will be 'one bright one dark', this to the line
1, the 'shadow' between longitudinal street lamp lighting:
due to the unreasonable design, light spacing is too big or the light distribution curve of lamps and lanterns along the road vertical illumination Angle is too small, leading to low between light and the light intensity of illumination. This road will be 'one bright one dark', which bring great visual fatigue driving.
2, 'shadow' between transverse street lamp:
due to the unreasonable design, the height of the light pole, the elevation of lamps and lanterns is not enough, or the light distribution curve of lamps and lanterns along the road horizontal illumination Angle is too small, leading to the central part of illuminance is too low, it will also bring many inconvenience to traffic.
3, 'shadow' crossroads lighting:
because of intersection are mostly 'wide', arrange installation by normal street alone, never even illumination requirements, some intersections between illuminance is very low. The solution can be installed separately or additional light pole and lamps and lanterns half light, the intensity of illumination value should be stretch intensity of illumination of 1. About 5 times, thus avoiding the driver for pavement illuminance suddenly reduce affected the visual, to reduce the number of traffic accidents.
