Arri-style Large Ringlight

cults3d

This ring-light fits on cinema-style support-bars of 15mm or 19mm according to the Arriflex system. It allows for nearly all the large lenses and is specifically made to fit Master-Prime lenses. For smaller lenses, light-shields can be fitted. I made this specifically for hand-held or Steadicam use, the added weight is approx. 1200 grams. This is specifically made for the new generation of adjustable and high power LED strips. Originally I made 2 versions: a Warm-white version made from short LED strips that can be found in the fluorescent replacement tubes. These strips were cut in pieces and reconnected in such a way that they only needed 12 volts. A 3 channel dimmer (400 Hz) was used to divide the circle in 3 segments so a less symmetrical lighting can be made.Fixed with hot-glue. The supplied STL is from the next, RGB version, but the single color STL is available when requested The second version is with an RGB-WW-CW LED-strip of 5 meters @ 24 volts. This is controlled by a wireless with a dedicated remote control. The strip is spiralled in the hood and fixed with hot-glue and it's own adhesive backing. For the constant light output it is advisable to use a DC-DC boost converter, which should be strong enough to supply the needed amperage, when using a Li-Ion battery (up to 8 amps!)
