Abstract (en)

[origin: WO0071928A1] A lighting device with an aperture lamp (1) comprising two series-connected optical means (8, 9), whereby at least the first optical means (8), when seen on a cross-sectional plane perpendicular to the longitudinal axis of said lamp, is curved. The first means (8) focuses the broad distribution of light beams which are emitted by each surface element in the region of the aperture in the direction of the normal of each respective surface element. The second means tilts at least part of the bundle of light coming from the first means at angle of inclination which can vary in size for at least one part of said bundle of light. This enables the light emitted from the curved surface of the aperture to be directed in a targeted manner, e.g. in a parallel manner.
