|At an exhibition (DSE) and a shareholder meeting, the danish engineering consultancy company COWI wanted to profile their energyefficient and environmentfriendly image. Therefore they wanted to construct a exercisebike with a generator that is connected to energyefficient LED illumination. The light intensity should be proportional to the amount of energy produced by the person on the bike. The more energy produced, the more intense light.
There should be made two different versions. One for the shareholder meeting emitting a green light, designed as an over-size-arkitect lamp (see picture to the right), and one for the DSE exhibition consisting of 7 warm white LED spots to illuminate the posters. COWI hired AKJ Inventions to make the control electronics for both versions.
For the arkitect lamp there were used 4 green Lamina Atlas LEDs. For the exhibition there were used 7 VS-P3 LED spots from Vossloh-Schwabe.
