How to solve the shadow of road lighting solar street lamps

Lighting 'shadow' : 1, crossroads because of the intersection are mostly 'wide', arrange installation by normal street alone, never even illumination requirements, some intersections between illuminance is very low.

1, the 'shadow' crossroads lighting: because the intersections 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. 'Shadow' between 2, longitudinal street lamp lighting: due to the unreasonable design, LED street lamp, lamp 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', which bring great visual fatigue driving. 'Shadow' between 3, lateral 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, the inner part of the pavement illuminance is too low, it will also bring many inconvenience to traffic. Solve these kinds of lighting to 'shadow' problem is main or basis in the design of road lighting, light and light is high, the right and the basic rule of high light, coupled with lamps and lanterns light distribution curve for the layout of the lamps and lanterns. The above problems mainly displays in lighting uniformity do not meet national standards, such as the level of road lighting total evenness should reach zero. More than 4 standard.
