dreipuls: rima curtain LED lamp

‘rima LED curtain lamp’ by dreipuls



affected by the idea of tangible interaction, the ‘rima desk lamp’ by german manufacturer dreipuls is designed to provide individual and flexible lighting. instead of controlling the light by using a conventional on-off switch, the position and dimension of areas illuminated can simply be defined by adjusting four rings stringed to the 90cm long fixture in a horizontal direction. moving any one of the rings will turn LEDs on and off – it is as easy as drawing a curtain.


developed using technology based on LEDs connected in series which are controlled by a processor, optical sensors detect the position of each ring and the processor then limits the power supply to the lights located between the two rings, so that they are the only ones to be switched on. additional functionality allows the user to adjust the light color and intensity as well as light direction by rotating a second ring which is mounted to the basic ring. using energy-saving LED technology, energy consumption does not exceed 12 watts even when all bulbs are switched on.
