LED FUTURE LIGHTING
access the full feature sets inherent in the fixture design. CE, Cineo Lighting: We agree that some new technologies in lighting need something more robust than five- wire DMX. Cineo sees sACN over Ethernet as a preferred technology in the future. We also support wireless DMX/RDM in all our new lights. We expect there will be years of hybrid communication stage environments with traditional DMX/RDM blended with wireless and more advanced Ethernet lighting systems. Some floor lights will be on wireless controlled by an iPad. DMX with RDM still works very well through consoles for much of the lighting in the rig. But when we add Enhanced Environments with LED panels these require Ethernet networks. So we see hybrid networks for lighting as the reality in the near future. Most consoles and control systems already support this types of implementation. Cineo’s new LightBlade products are adding Ethernet ports as well in anticipation of this new direction. MW, ARRI: Certainly the fixtures of the future will generate more data and will more closely resemble computers. However, I’m not sure that fixture will be dependent on data. They might generate metadata and this could be of benefit to some users. These data structures will be designed to fit the needs of the customer. Def: How much will the QC’ing of LEDs be a factor in their evolution? Is the process of LED binning a concern to manufacturers or are there processes that will keep colour properties consistent? ADeM, LiteGear: The colour consistency of LEDs is getting better every day. At LiteGear, we QC 100% of several hybrid (bicolour) products and have nearly eliminated colour variations. Companies that make the actual

PIXEL-BASED LEDS ARE BASICALLLY VIDEO WALLS, IT ALL COMES DOWN TO THE TASK OF THE FIXTURE
MW, ARRI: The QC process is extremely important. Binning is one way to start with ensuring the quality of the LEDs. At ARRI, we have many more ways to make sure the quality never wavers. It is our practice to put all of our fixtures’ light engines through a calibration process that will adjust the colour quality based off the LEDs in that particular lamp head and according to temperature variations. This will always ensure quality. Def: How quickly will individually microchipped controlled pixel- based lighting be ushered in to the market? What is its potential? BB, Litepanels: Pixel-based lighting for specialty applications (the replication of video effects, for example) will come to the market within the next five years. The challenge in this area will be brightness, since the OLEDs used are not as bright as other LEDs. KH, Sumolight: It will hit the market soon but we see it primarily as tool for special effects. FH, Kino Flo: This is dependent on market demand and what it is prepared to pay for it. Pixel-based LEDs are basically video walls. It all comes down to the task of the fixture. Why pay a premium for pixel based lighting instrument when all you need is good skin tones?
finished LED package are constantly improving the process, but more importantly they are being held to a much higher and tighter standard. BB, Litepanels: Quality control of LEDs will continue to be a critical factor in creating top-quality LED lighting. In addition to tight binning, most top-quality, multicolour LED lighting products will also be calibrated at the factory to ensure consistent and accurate colour performance. Litepanels specifies tightly controlled binning for all LEDs and final testing and calibration of colour and optics at our factory. KH, Sumolight: Yes, it has a large impact on the consistency of the LEDs. Still we need to calibrate every single light. FH, Kino Flo: Colour binning is a function of the LED manufacturing process. Phosphor blending and application to a chip is an imperfect art. Until a method of colour point consistency can be achieved in the manufacture of an LED chip you will have to depend on binning. Rich Pierceall, CEO, Cineo Lighting: Binning for colour and efficacy consistency is a critical step in building high-quality lighting instruments. Combining this level of QC with the ability to field-calibrate fixtures will assure the investment in LED technology will fulfill its full return on investment.
