A STREET LIGHTING ARRANGEMENT

摘要

Present invention relates to a street lighting arrangement comprising in the casing having a planar window LED light sources attached to the surface S0 of the cooling element. Each LED light source is surrounded by three reflecting surfaces S1, S2, S3, beginning closely from the surface S0 of the cooling element. Main reflecting surface S1 of the LED light source has trapezoidal shape. Main reflecting surface S1 is adjoined by two lateral triangular reflecting surfaces S2 and S3. Second lateral triangular reflecting surface S3 is connected by its edge to the fourth triangular reflecting surface S4. Reflector surfaces of two adjacent LED light sources are combined into a single reflector module by the connection of the edge of the fourth triangular reflecting surface S4 of one LED light source to corresponding edge of the second lateral triangular reflecting surface S3 of the adjacent LED light source.
