Abstract
A projection system for a vehicle, in particular for an ambient lighting device for generating a plurality of light cones for illuminating the ground in the surroundings of the vehicle, includes at least one light source and a microlens array. The microlens array includes an optical axis, a first portion with at least one first channel and a second portion with at least one second channel. The projection system includes an optical device that is provided downstream of the microlens array and is arranged at least in the area of the first portion, with the distance between the microlens array and the optical device being less than 20 mm. Light emitted by the light source, which falls through the at least one first channel of the first portion, is deflected by the optical device by a first angle with respect to the optical axis and forms a first light cone, and light emitted by the light source, which falls through the at least one second channel of the second portion, is deflected by a second angle with respect to the optical axis, which differs from the first angle, and forms a second light cone.
