Patent ID: 8210706

Claim:
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 light sources comprising at least one LED having a substantially planar light distribution pattern, the first array being directed at an angle intermediate to the axis and the cut-off angle; a second array of light sources comprising at least one LED having a substantially planar light 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 comprising a plurality of reflecting surfaces positioned to receive light emitted from the first array at angles greater than the cut-off angle, the first reflector comprising a portion positioned to reflect a portion of the light from the first array at close to the cut-off angle as a substantially parallel beam generally in the direction of the second array; and a second reflector comprising a plurality of reflecting surfaces positioned to receive light emitted from the second array at angles greater than the cut-off angle, the second reflector comprising a portion positioned to reflect a portion of the light from the second array at close to the cut-off angle as a substantially parallel beam generally in the direction of the first array.
