LEDs light up Las Vegas at the ETS-LDI show
The Entertainment Technology Show-LDI, held in Las Vegas in late October, presented a wide range of LED-based products for both display and lighting applications.
With ETS-LDI following so close after the PLASA show in London, it was inevitable that many companies would show similar product lines, but there were plenty of new innovations on display. The most important topic at the show was the ongoing patent lawsuits between Super Vision and Color Kinetics, which could have serious implications for the rest of the industry.
Unlike last year, when LED products featured heavily in the ETS-LDI Awards, only one LED system was honored. SGM's Palco floodlight won Best Lighting/Architectural Product of the Year. The system, a super-bright color-changing floodlight for outdoor use, uses multiple 3 or 5 W LEDs.
New product releases at ETS-LDI
New product releases at the show included the following:
LED floors and curtains
The same technology has been used by Staging Dimensions Inc to embed a grid of LEDs under inch-thick transparent panels to form a modular decking structure (Pixel Panel) that can be used to create a stage with color-change capabilities.
Elsewhere, Lightspace Corporation entertained visitors to its stand with a game of LED dodge ball, in which players were chased by a ball of light around a floor constructed of panels illuminated by LEDs. The unique feature of Lightspace's floor is that the 16 x 16-inch panels also contain pressure sensors, allowing the LED lighting to respond to people walking or dancing on the surface.
Neon-like bendable strips containing LEDs were a relatively common sight, although iLight Technologies had a different twist - white. The company's Plexineon series includes three color temperatures of white - 3500, 4500, and 6500 K - which are all achieved using blue LED chips. The patent-pending light conversion technology is being kept under wraps but a clue is seen when the tube is viewed with the LEDs off. The tube itself has a yellow tinge, implying that the downconversion process necessary to create white light takes place in the tube itself. (To make the most common form of white LED, the emission from a blue LED chip excites a phosphor material that emits in the yellow region; the combination of blue and yellow emission makes white).
Dynascan showed its 360-degree LED display, built around a central rotating drum that contains a number of LED modules. Media Impact Networks and Optispace showed much smaller cylindrical, spherical and circular displays, with one or two rotating LED modules. Media Impact Networks intends its display to show video and be remotely addressable, providing a low cost, reconfigurable advertising tool.
The next ETS-LDI show will be held November 11-13, 2005 in Orlando, Florida.
