Abstract

LED lighting device comprises an optical system (3) with at least two lenses, the first of which is an aspherical lens (5) and a second concave lens (6) arranged between the first lens and the LED (2). The inner and outer radii of curvature of the second lens conform to a logarithmic espression.
