    摘要： A lens having a first surface (1) and a second surface (2). The first surface (1) and the second surface (2) are mirror symmetric to a first symmetric plane (A) passing through an optical axis (Y) of the lens and extend in a first direction (X) perpendicular to the optical axis (Y). The curve profiles of the first surface (1) and the second surface (2) on the cross sections perpendicular to the first direction (X) are configured in such a way that light emitting from a light source (3) arranged at a predetermined position of a second surface side is refracted by the first surface (1) and the second surface (2) to be emitted in a direction which is offset from the optical axis (Y) by more than a predetermined angle.

    摘要： A lighting system comprising a plurality of electronic converters (10) and a plurality of lighting modules (20) is described. The lighting system also comprises switching means (40) configured for connecting the lighting modules (20) to the electronic converters (10).
    In particular, the switching means (40) are configured to allow at least two switching states. In the first switching state, at least one lighting module (20) is connected to each electronic converter (10). Instead, in the second switching state, at least one electronic converter (10) is disconnected, and the lighting module(s) (20) connected during the first switching state to the electronic converter (10) are connected to the other electronic converters (10).
    The lighting system also comprises a control circuit (42) configured to detect one or more signals indicative of the supply powers required by the lighting modules (20), and to drive the switching of the switching means (40) to activate the first or the second switching state according to the supply powers required by the lighting modules (20).
