Installations formed by blending colored lights, and a lamp based on jellyfish were produced by Dutch designer Dennis Parren for the Biennale Internationale Design Saint-Etienne 2015. Three projects by Studio Dennis Parren were installed at the Puits Couriot Parc-musée de la Mine – an historic mining site that has been turned into a museum and public park in Saint-Etienne, central France.
Shown as part of the city’s 9th biennial design earlier this year, all of the designs built on Parren’s work with controlled RGB lighting – using red, blue and green LEDs to create multi-colored patterns and shadows on surfaces where the light overlaps in different combinations. He has previously produced a lamp and a light bulb that cast colored shadows using a similar technique.
For his Gradient installation, colored lights and white light were projected at slightly different angles onto a surface of protruding white polystyrene shapes with round bases and a pair of slanted faces that joined along the top. Each of the faceted forms was angled differently from its neighbors, so the blend of colored light changed gradually across the floor as different surfaces picked up and reflected different projections.
The LEDs were slowly rotated so different overlaps of the RGB combinations were created on the surfaces, causing an effect that made the colors appear to flow across the spiky carpet. Parren used exactly the same lighting technique for another installation called Reflections, which replaced the polystyrene shapes with more angular and uneven forms made from the material.
Zigzagging ridges laid out horizontally in arrangements parallel and perpendicular to one another were designed to trap the colored light and reflect it multiple times between the surfaces. The amplified reflections formed color gradients on each of the planes, which again shifted when the LEDs were rotated.
