The television news is essential for the dissemination of information. Ensuring that information is presented in a clear and engaging way requires not only high-quality cameras, audio equipment and displays, but also lighting. Over the past decade, many information stations have switched to LED lighting technology due to the many long-term benefits that are worth it and the possibility of improving a segment’s decor design. to the other with just the push of a button. Although their most notable characteristics are their brightness, extended color capabilities, and reduced maintenance, LEDs also consume less power and reduce thermal loads – a real victory for broadcast organizations – but only when they are. correctly supplied.
The need for good power control is something Jonathan Huff, CEO and President of Alaska Universal Productions (AUP), understood when Alaska’s News Source, NBC’s local branch in (town), pointed out. asked to upgrade their studio lighting system. The studio consisted of two broadcast studios with over a hundred LED fixtures as well as several video walls mounted around the studio that required a reliable, simple and scalable power control system.
“The studio was new to Alaska’s News Source, but it wasn’t ready for prime time, so to speak, and they were on an FCC deadline to put it up and running,” Huff said. “There were cables going from one side of the studio to the other, then back to the light next door. The fixtures were controlled by DMX, but the original design and preset didn’t completely shut down the fixtures. And this is a problem for new LED technologies containing computer chips. If they are constantly on 24/7, it ages them unnecessarily.

Although the lights were dimmed to no longer emit light, power was still reaching them. This increases energy costs, constantly generates heat in the device, which causes its internal fan to turn on constantly. This cycle will not only damage the instruments, but can also wear them out prematurely and unexpectedly increase maintenance costs.
A power control platform
AUP worked on designing a system that would put the lighting system up to par, giving them clean and simple power control. Because the station broadcasts a show almost every half hour with as little as a two-minute break in between, their main goals were to enable fast and efficient lighting presets to support the busy network schedule, eliminate the large number of cables that snake around the studio; and ensure that the studio’s lighting investment was as functional, energy efficient and cost effective as possible.
AUP reworked the entire lighting grid, incorporating existing and new lighting for a total of 150 fixtures, which were a mix of ETC Source Four, Philips Selecon PLCyc and several Brightline fixtures. In addition, they installed almost 1,000 feet of pixel tape. To provide engaging infographics and videos for display during the news segments, video walls have been integrated around the facility, including a Samsung 3×3, 2×2, 2×4 video wall and an LED video wall. To turn all this LED gear on and off, a robust power control platform compatible with DMX control was needed. Enter LynTec automated power control panels.
“I’ve seen LynTec at trade shows and thought this would be a great product for that,” Huff said.
Together with Matt Skjerven of Image Marketing West, his manufacturer representative, Huff selected two LynTec RPCR-16 automated relay panels for a total of 32 automated power control circuits for the lighting and video system in the new broadcaster studio. The remotely controlled smart relay panels manage power to the LED fixtures and allow individual control over each circuit, providing the flexibility that would previously have come from a dimming system. In this way, the lighting control system can turn individual circuits off and back on to give an occasional forced restart to LED luminaires or to allow service in one area while maintaining lighting in another.

Once the electrician had wired the panels, all that was left was to plug in the network cable and launch the LynTec web GUI to set the control options for each circuit. The lighting system has been programmed to be controlled from the studio lighting console to completely shut off power to the LED fixtures as well as to sequence the video walls, ensuring that they do not consume any electrical power. standby when not in use and are protected against damaging current draws when powered. to.
“Broadcasters like Alaska’s New Source are responsible for delivering the information and can’t afford their systems to fail in the middle of the segment, I knew I needed a product that wouldn’t fail. LynTec is great, super simple and reliable, ”concluded Huff.
