Martin, the Denmark-based company that recently licensed RGB color-changing LED technology from Color Kinetics, showed 2 LED prototypes. One was the LUCI 40 LED curtain (pictured), a series of acrylic tubes containing RGB LED pixels with a spacing of 40 mm, that can be built into a display with a transparency of 60%. Observers could not help notice the similarity with a much older product from G-LEC…The other Martin product was the Stagebar 54 containing Luxeon K2 emitters in the ratio of 2 red, 2 green, 2 blue, 2 amber and 1 white per pixel. This RGBAW combination of LEDs was different from the usual RGB approach, but not unique: LDDE had an RGBAW fixture, while James Thomas had several RGBA fixtures. Leader Light, in contrast, went for a different combination of AWB – amber, white and blue. Copyright (c) 2006 Cabot Media Ltd.
