Abstract
A street lighting arrangement for providing light distribution over an angular range between an axis and a cut-off angle, the arrangement comprising a first array () of at least one LED () having a substantially planar distribution pattern, the first array being directed at an angle intermediate to the axis and the cut-off angle, a second array of at least one LED having a substantially planar distribution pattern, the second array being directed at an angle intermediate to the axis and the cut-off angle and generally opposite to the first array, a first reflector () directed to receive light from the first array () beyond the cut-off angle and reflect it as a substantially parallel beam in the direction of the second array at close to the cut-off angle and a second reflector directed to receive light from the second array beyond the cut-off angle and reflect it as a substantially parallel beam in the direction of the first array () and at close to the cut-off angle.
