Abstract:
A lighting device comprisinga plurality of light sources disposed in a common horizontal plane about a vertical axis, each said light source including a light emitting diode element in said horizontal plane for emitting a light in a diverging pattern about said horizontal plane; anda curved optical lens disposed about said vertical axis and intersecting said horizontal plane, said lens having a plurality of focal points for effecting a concentration of light from said light sources about said horizontal plane, each said focal point being disposed in a vertical plane passing through said vertical axis perpendicularly of said horizontal plane; whereineach said light emitting diode element is positioned in a respective vertical plane at a greater distance from said vertical axis than said respective focal point in said respective vertical plane to minimize divergence of light from said respective light emitting diode element about said horizontal plane.
