A lighting device for emitting illumination light includes an LED configured to emit light emitting diode radiation, a laser configured to emit laser radiation, and a phosphor element configured to at least partly convert the LED radiation and the laser radiation into a conversion light which at least proportionally forms the illumination light. The LED, the laser and the phosphor element are arranged relative to one another in such a way that during the operation of the lighting device on an incidence surface of the phosphor element in each case in the time integral the LED irradiates an LED irradiation surface with the light emitting diode radiation and the laser irradiates a laser irradiation surface with the laser radiation. The laser irradiation surface and the LED irradiation surface are free of overlap.

The invention relates to an optical guide made from transparent or translucent material extending along a main direction and including a rounded, tubular guide portion formed with a rounded, tubular dioptric interface, the tubular guide portion being suitable for guiding light along the main direction through successive reflections off the dioptric interface with a rib adjacent to the guide portion that is suitable for allowing light to exit the tubular guide portion. The rib exhibits a variable shape along the main direction so as to modify the amount of light that exits along the main direction. The invention also relates to a lighting module that includes the optical guide and a lighting device that includes the lighting module.

A lighting device includes an LED, a light guiding member, and a mask member. The light guiding member has a cut to provide a directivity to light emitted from the LED.
