Abstract

A lighting system comprising a plurality of controllable light emitting elements is disclosed. The lighting system further comprising a spreading optical element arranged in front of the plurality of light emitting elements to shape the light emitted from the lighting elements, and a controller for varying a light emission angle range of light emitted from the spreading optical element by controlling each of the plurality of controllable light emitting elements. This allows the light emitted from the spreading optical element to be varied without varying any physical parts of the lighting system, because the controller now controls each of the light emitting elements, by e.g. dimming one or more of the light emitting elements or by switching one or more of the light emitting elements off.
