With RIMA, by Germany based industrial designer Matthias Pinkert, one can now easily define the position and range of his desk illumination.
By sliding any of the rings, placed around the central tube, in horizontal direction one turns on and off the LEDs. Additionally one can adjust the angle of light, intensity and light color by rotating a secondary ring on the base ring. You can also switch on a second lightning area based on the same principles. By selecting a small light area one can simply reduce the energy consumption.
RIMA is awarded with a reddot design award in product design in 2010.
