Press Release Summary:
With focusing lenses and LEDs distributed across rectangular area, LED-Series 2000 series creates even, consistent lighting pattern across target area so that operators can spot defects at full production speeds. There are 10 models available, which emit 2,000 lux and collectively cover areas from 10 cm to 2.5 m wide at 50 cm from light to inspection zone. Controlled by varying light intensity and duration, light output does not suffer from arc wander or flash to flash variation.

New Unilux LED-Series 2000 Stroboscopic Inspection Lights Combine Green Tech and Traditional Power
Manufacturer to preview powerful new generation at LabelExpo Americas 2012
Saddle Brook, NJ -- (http://www.myprgenie.com) -- Unilux has put the old and new into a single stroboscopic inspection light with the introduction of its new LED-Series 2000 family of LED strobes. The new lights combine the operational and environmental benefits of LED lights with the power of traditional xenon-based strobes plus a few more operational benefits, according to Mike Simonis, president, Unilux, who will preview the new lights at LabelExpo Americas 2012 in Chicago, Sept. 11-13 -- Booth 1457.
"These are not your father's strobe lights-- or even your father's LEDs," Simonis said. "They are five times brighter than our first generation of LED strobes. This gives them the same lighting performance as our proven xenon-based lights with only 25% to 35% of the power consumption of our comparable Lith-O-Light strobes, and that's where the comparisons need to be made. Our new LED-Series 2000 strobes are also smaller -- about one-third the size of the traditional equivalent -- and lighter than the xenon lights and have a greater flash-rate range. All this gives printers and converters many, many more options for mounting lights and adjusting flash rates to maximize inspection capability at full production speed and reduce the fatigue factor for inspection."
The new LED-Series 2000 family comes with a new product-naming convention that corresponds to the coverage area (in millimeters) 50cm (20in.) from the light to the inspection area. The new LED-Series2000-500, for example, which replaces the LED 5X2, will emit 2000 lux of illumination on a 500mm width from a distance of 20 in. This is five time more light than the LED 5X2 produces. In fact at a flash duration of 35 microseconds, the LED-Series2000-500 puts out as much light as the xenon based LOL IV-20.
"The LED-Series 2000 family gets its name from the fact that at a distance of 50 cm the lights will produce a light intensity of 2000 lux," said Matt Runo, chief engineer, who led the year-long R&D effort to develop the new lights. "While the amount of light produced is the same as the xenon lights which have been workhorse products for years, there's a big technical difference. The lens designs for the new LED-Series 2000 strobes provide a sharper focus than the xenon lights. This benefits the user by concentrating more light on the inspection area with less spillage outside the area of interest. Getting the same output or more as a xenon-based strobe was our key objective because light output (brightness and coverage area) was a major issue with our first LED strobes.
"Our LED-Series 2000 family has raised the bar for stroboscopic inspection lighting in three critical operating areas," he continued. "First, the distribution of the LEDs' across a large rectangular area combined with focusing provided by the lenses creates an even, consistent lighting pattern across the target area, so customers will be able to inspect an area comparable to the LOL family but with an even more uniform illumination. A second benefit is that an LED's inherent light output is extremely stable and does not suffer from the arc wander and flash to flash variation associated with xenon-based lights. This benefits the user by reducing fatigue and increasing inspection effectiveness."
The third benefit, Runo pointed out, is the flexibility for mounting locations due to its smaller size and the ability to control the lights output.
"Light output is controlled by varying both the light intensity and the duration or on time of the light. The perceived light intensity seen by the user is actually a relationship between the intensity of light and the light duration," he said. "A longer pulse rate, say 65 microseconds, gives you more light, but the sharpness of an image frozen by the action of the strobe degrades with longer durations. A longer duration can work well for repeat patterns with larger images. But when you have something small with fine detail, then you need a shorter duration for improved clarity. With our new LEDs, you can dial down the light duration to as short as 10 microseconds and mount it close enough to the web so that you can see the fine details. The light duration of the xenon strobes can't be controlled so they don't have the same flexibility provided by their LED counterparts."
In field testing at a cigarette tipping paper facility, where applications included tipping papers with metallic leaf and packaging materials, Simonis said the reaction came down to one word: "Wow. That was all they said when they turned on the light."
LED's can last five to eight years, depending on use, and they lower the cost of ownership by eliminating the need to change lamps, avoiding unscheduled outages and lowering power consumption. They do not create ozone during operation, and they require no special disposal methods when they burn out.
The LED-Series 2000 family of stroboscopic inspection lights includes 10 models from the 100 to the 2500 covering 10cm (4") to 2.5 meters (8'). Unilux products range from handheld, battery-powered units for spot or narrow-strip web inspection or maintenance and troubleshooting applications to fixed-mount units capable of inspecting surfaces up to 36 feet (10.9m) wide. Unilux solutions enable operators to spot defects at full production speeds and use their knowledge of products and production systems to determine the severity of defects and find and eliminate their causes. Unilux lights are designed to withstand industrial environments, including the heat and humidity of steel and paper mills.
Unilux Inc., headquartered in Saddle Brook, NJ, is celebrating 50 years of designing and manufacturing industrial surface inspection lighting systems for the textile, printing/converting, metals and papermaking industries and heavy-duty strobe lighting systems for the film and video industry. Unilux stroboscopic and pulsed LED inspection lights ranging from handheld, battery-powered units for spot or narrow-web inspection or maintenance or troubleshooting applications to fixed-mounted units capable of inspecting surfaces up to 12m wide either individually or in combination.
