Abstract:
The invention provides an LED module (1) having a concentrated light output window. Light output from a first output window (115) of an LED assembly (110) (e.g. from a plurality of LEDs) is passed to an input window of a light directing element (120) and redirected to be emitted from a second, smaller output window (125) of a light directing element. This difference in size thereby concentrates the light output by the light directing element. The second output window (of the light directing element) is substantially perpendicular to the first output window, allowing for the size of the LED assembly in a particular dimension to not be necessarily constrained by the size of the second output window.
Abstract:
The present invention relates to a lighting device, in particular a headlamp for vehicles, at least comprising an array (1) of light sources (2), consisting of first and second light sources (2) being mounted within the same flat or curved plane, and a projecting optical system (3) arranged to project light emitted by the light sources (2) in a forward direction of the lighting device. At least one shifting element (6) is arranged in front of said first light sources. The shifting element (6) generates real or virtual emission positions of the light of said first light sources shifted towards or away from the projecting optical system (3) with respect to emission positions of said second light sources. With the proposed lighting device, in addition to the main lighting function of illumination, a pattern or signature can be projected at one or several additional image planes. The lighting device thus e.g. allows the additional projection of branding or safety patterns.
