LED FUTURE LIGHTING
in love with halogen light, because the warmth and the continuous spectrum seems to talk to their souls and addresses their needs for comfort and feeling safe, and being at home. While if you visit the house of a friend, which is lit totally with energy-saving lamps, you might have the feeling that this freezes your soul. LEDs are somewhere in between, some of this kind, some of that kind, but the differences of personal interpretation will prevail for some time to come. Rod Gammons, MD, Rotolight: LEDs have been the driving force behind the pace of change in the photographic and broadcast industries. LEDs are 96% more efficient than tungsten lights leading to significantly lower operating lighting to meet new efficiency targets, with no exceptions, from September 2020. FH, Kino Flo: It has already superseded traditional lighting. Look around you. We are in a world of artificial light sources. LEDs are being legislated into the market. There is nothing to hold it back. SH, Pinewood MBS Lighting: One example of an environmentally sustainable future for the industry is our recent costs. In fact, the EU Ecodesign Working Plan would require all
next year that significantly increases the power achieved within an LED hard light. MW, ARRI: There are fewer options for high-output directional sources because of the heat limitations. There are physics limitations where a LED source, let’s say the output of a M90, would have to be extremely large and heavy to get the same output because of the cooling that would be required to keep the LED ‘happy’. A very large and heavy device of this kind would not be a benefit to the market. As technology advances it might be possible to achieve this, but it is hard to say how long that would take. Def: How quickly will LED lighting supersede traditional lighting? What will hold it back? BB, Litepanels: Replacing existing stocks and infrastructure is costly, but since LED sources pay for themselves in energy savings after only a few years, this barrier will gradually fall. We are finding that most installations are geared towards LED technology, whether it’s a new install or an upgrade of a facility’s existing equipment. DW, Dedo Weigert Film: There are many people in our business who are still
demand changes you will see more options. Steve Howard, Technical Director, Pinewood MBS Lighting: The technology for delivering quality, uniform LED illumination is advancing almost by the day. Whilst matching the sheer output power of some larger ‘traditional’ fixtures may still present certain challenges, it is just a matter of time before we see a complete shift in the balance between the use of old and new technology. RP, Cineo Lighting: This will change next year… watch this space. CE, Cineo Lighting: LEDs have hard limits on power density. Basically they overheat if too much power is in too small a space. There is a principle in optics called ‘etendue’. Basically the size of the source determines the size and spacing of the optics needed. When a camera uses larger film for example all of the optics and the camera body have to scale accordingly. The same is true with lights. Incandescent and HMI bulbs create an enormous amount of power in a very small space. LED technology is still catching up. This is a technical challenge our company is investing heavily in and we look forward to bringing out an LED product in the
