I. Selection of solar street lights.

1. Pole height selection: the height of the pole is generally selected according to the width of the road, choose the same or slightly greater than the width of the road and the best height of the street light pole. Generally single-lane rural roads choose 3-4m light pole; double-lane rural roads choose 5-7m light pole; four-lane or traffic trunk road choose 8-12m light pole; courtyard or other scenes lighting is based on the lighting range to choose.

2. LED light head wattage selection.

Should be based on street light use, pole height, LED street light lumen value (TUWR solar street light selection industry's top Japan Nichia [210 lumens / watt] LED SMD) to determine the street light wattage.

In general, roads and scenes with less pedestrian traffic can choose a slightly lower wattage LED head, while roads and scenes with more pedestrian traffic can choose a slightly higher wattage LED head.

3-4m pole recommended to choose 15-20 watt LED head; 

5-7m pole recommended to choose 30-50 watt LED head;

 8-12m pole recommended to choose 50-100 watt LED head;

 according to the actual situation can choose double LED head street light.

3. Selection of flange diagonal dimensions and cage diagonal dimensions.

First of all, the diagonal size of the flange and the diagonal size of the ground cage must be unified in order to carry out matching installation. In general, the higher the height of the solar street light pole, the larger the diagonal size of the flange and cage, and the higher the height of the cage.

3-4 metre poles choose a flange diagonal size and a ground cage diagonal size of 240mm.

5-7m poles choose flange diagonal size and ground cage diagonal size 260mm; 8-12m poles choose flange diagonal size and ground cage diagonal size 280mm.
