DEDOLIGHT OPTICAL ACHIEVEMENTS PART 4: LED LIGHTING

Dedo Weigert discusses the development of different lighting technologies: from Halogen lamps to Metal Halide (HMI), and the long road to the perfection of LED technology.

LED lights bring distinct advantages – the most obvious being: bi-colour lighting, low power consumption, and low heat output from the front of the light. This in combination with the fact that LED lights can be powered for long periods from battery power, makes these suitable and desirable for many filmmakers and crews.

"It took us several years to perfect this technology, and we are proud to say that finally it all works to our satisfaction. But since we are now looking into larger LEDs with even higher power, we have to expect that again the design and all the testing involved to make it all work may still take a long time and many different approaches for the super power LED light sources. That we already have, but we need to integrate them to now cooperate with new optical designs and new advanced super cooling systems, borrowed to some extent from computer technology. Maybe it is still worthwhile to add that our mono-color LED lights stay as close as possible to the book values for tungsten light with 3200 Kelvin, and the daylight as close to the value of theoretical daylight with 5600 Kelvin; whereas our bicolor lights go below and above these values, namely from 2700 Kelvin all the way to 6500 Kelvin."
