LIGHTING SYSTEM WITH GRAVITY-CONTROLLED LIGHT BEAM Russian patent published in 2014 - IPC F21V14/02 F21V14/04 F21V14/06 F21V17/02 F21V19/02 

FIELD: electricity.

SUBSTANCE: proposed lighting system comprises at least one light source and at least a first optical element. The light source generates a light beam, and the first optical element refracts the light beam. The light source and the first optical element are configured so that the light source and/or the first optical element may be moved under the influence of the gravitational field so that the distance between the light source and the first optical element depends on the orientation of the lighting system relative to the gravitational field. The system comprises a second optical element which is fixedly mounted on the housing. The first and second optical elements are contained in the housing. The first optical element is a positive lens, or a matrix of positive lenslets. The second optical element is a negative lens or a matrix of negative lenslets. The first optical element is located between the light source and the second optical element.

EFFECT: elimination of distortion of the emitted light beam is ensured.
