Title: Lighting system with gravity controlled light beam

Abstract: A lighting system (10, 50, 70, 90) is provided comprising at least one light source (21, 91) and at least a first optical element (22, 92). The light source (21, 91) generates a light beam (12) and the first optical element (22, 92) refracts the light beam (12). The light source (21, 91) and the first optical element (22, 92) are arranged such that the light source (21, 91) and/or the first optical element (22, 92) are movable under the influence of a gravitational field in such a way that a distance between the light source (21, 91) and the first optical element (22, 92) is dependent on an orientation of the lighting system (10, 50, 70, 90) with respect to the gravitational field.
