SOLAR TREE LED 2nd GENERATION
Solar powered street lamp
Solar Tree is a light fixture combining an innovative design with the technical performances of LED lighting systems using solar energy supplied from photovoltaic system.Structure composed by curved steel poles of different diameters and heights, with a maximum total height of about 5,5m over road level. This system is composed by 10 “stems of grass”. On their extremity there is 1 LED protected by a diffuser screen in PMMA and 10 poles supporting the heads.The poles are painted with outdoor epoxy paint in light green colour shading into white. The 10 heads, housing the photovoltaic cells in their upper part, are supported by poles; 20 power LEDs are housed in the lower part of 4 of them, on an aluminium dissipator, and are provided with a screen in plastic material which ensures protection against water and dusts. The base is made of hot-galvanized steel plate to be fixed to the ground. Otherwise it is possible to use a base, always in galvanized steel, with reinforced concrete parts forming a circular bench. In this case the base can rest on the ground without need of further fixing systems. Benches in white painted concrete, with second coat of anti-graffiti paint.
