Dimming specialist IES showed its iSine dimming technology, which it claims is the world's most advanced sinewave dimming technology. With a number of high profile installations across Europe and a Best Product Award from this year's Showtech exhibition in Berlin, the Dutch manufacturer has some weight to back up its claim. With iSine, IES dispenses with what it calls the 'mature' phase control techniques of conventional dimming systems, which inherently create unwanted noise and harmonic distortion because of the way they 'chop' into the wave form. iSine technology's far greener solution employs an Insulated Gate Bipolar Transistor (IGBT). For more on IGBT, sinewave dimming and dimming technology in general, see this month's Technical Focus feature on installed dimming systems.
