Abstract
The invention concerns a light unit with at least one LED, which includes at least one light-emitting chip as light source, with at least one fiber-optic element optically connected after the light-emitting diode and widening in the light propagation direction, and with a secondary lens optically connected after the fiber-optic element, in which oppositely arranged surfaces bordering the fiber-optic element, which form a bottom surface and a cover surface in a longitudinal section intersecting these surfaces, have oppositely curved curve sections adjacent to the light entry surface, as well as such a fiber-optic element.A light unit with high light output requiring limited space is developed with the present invention.
