A lighting device for vehicles with a semiconductor-based light source and an optical unit having an imaging device for producing a predetermined light distribution and having an optical element arranged between the semiconductor-based light source and the imaging device. The optical element has a back side facing the semiconductor-based light source and has a front side facing the imaging device. The optical element is formed as a color correction element which has a color correction-free partial surface area through which a firstly emitted partial light beam of the semiconductor-based light source passes and has a color correction-affected partial surface area through which the secondly emitted partial light beam of the semiconductor-based light source passes in a border angle area.

According to one aspect, an LED package comprises a plurality of LEDs and a primary optic disposed adjacent the LEDs wherein the primary optic includes protrusions for mixing light developed by the plurality of LEDs.

A light source can comprise an optical element, one or more light emitting diodes, and an adjustment. The light emitting diode or diodes can emit light. The optical element can process the emitted light to produce an illumination pattern. The adjustment can change the relative positions of the optical element and the light emitting diodes or diodes, for example by moving some aspect of the optical element or some aspect of the light emitting diode or diodes. The positional change can change the illumination pattern. The adjustment can comprise settings so that the light source can be readily configured to meet predefined application parameters, for example according to IESNA roadway classifications.

A flame simulating assembly including a light source, a screen having a translucent region which subjects light from the light source transmitted therethrough to diffusion and a transparent region, and a flicker element for intermittently reflecting the light from the light source toward the screen, to provide images of flames in a predetermined portion thereof. The screen includes a fringe region positioned between the translucent region and the transparent region. The fringe region includes a number of diffusing areas for diffusing the light from the light source and a number of transparent areas positioned between the diffusing areas, to at least partially provide images of flames in the diffusing areas.
