Abstract
A lighting device includes a light emitting diode (LED) that has a main axis of light emission. The lighting device also includes a lens element positioned adjacent the LED. The lens element has a geometry defined by at least partial revolution of a cross-sectional profile around an axis of revolution. The lens element is positioned relative to the LED such that the axis of revolution crosses the main axis of light emission of the LED. The lens element is operative to apply total internal reflection to at least some light rays emitted from the LED.
