Lighting unit

A lighting unit comprising a closed body having a substantially continuous, pliable surface, wherein the closed body comprises a plurality of individually controllable closed compartments, a hardware controller and a plurality of light sources, wherein

• each of the light sources is connected to the pliable surface at a respective surface area of the pliable surface, whereby orientations of the respective surface areas and orientations of the respective light sources are linked,
• the pliable surface is configured to assume a plurality of different profiles with corresponding different orientations of at least part of the plurality of surface areas, and
• the hardware controller is configured to direct the closed body to adjust a shape of the pliable surface to a first shape such that a concentration of light is formed at a first area in a space illuminated by the lighting unit and to direct the closed body to adjust the shape of the pliable surface to second shape such that an other concentration of light is formed at a respective second area in the space that is different from the first area,
• wherein the closed body is configured to adjust the shape of the pliable surface by applying a fluid pressure to the plurality of individually controllable closed compartments located inside the closed body.
