LED Technology
Unilux LED strobe lights are the next generation of inspection lighting and your connection to exciting new capabilities. Their softer, more uniform light patterns make them ideal for inspecting highly reflective surfaces, such as foils, without hotspots.

Unilux LEDs deliver:
• Long-term operation – LEDs can operate up to 100,000 hours. Depending on your usage patterns, operating life can easily exceed five to eight years.
• Illumination without the worry of lamp replacement and downtime – Even if a few LEDs in a module fail, you will have ample light to inspect your product normally until you replace the LEDs.
• Flash range of 300 to 50,000 flashes per minute – Sync your flash rate with pulse contact and rotary encoder signals and adjust the pulse width to match your press run’s needs.
• Field Expandability – Simply attach Unilux LED strobe units to each other to increase coverage across wider webs. Their uniform lighting eliminates hotspots and visual gaps in highly reflective materials.
• Smaller footprint – LEDs’ compact size and lighter weight put more power in a smaller package, giving you more close-in mounting options for increased inspection capability.
• Spot and Flood light patterns – Focus light where it’s needed with an exact flash rate and pulse width for specific inspection needs or for troubleshooting and routine maintenance.

Matching Strobes to Applications
Traditional Xenon strobe lights remain the inspection light of choice for applications requiring higher light intensity at lower flash rates or when mounting conditions require a longer distance to the inspection subject.

Xenon strobes are required for using UV and black-light filters to inspect labels, currency, lottery and game tickets and other materials with hidden security codes and other markings to ensure security and authenticity.

Your inspection need for each specific application is still the driving force in selecting the best stroboscopic inspection light for the job. With our expertise and extensive product line, you can rely on Unilux to help you install and use the right inspection light.

Are LED Stroboscopes Right for You?
For about 20% of your needs, the answer is a resounding YES! For the rest, our traditional, powerful and robust Xenon strobes are still your best choice.

The key questions to ask are:
• Do I want to reduce my carbon footprint?
• Do I want to reduce my downtime by eliminating lamp replacement?
• Do I want to lower my energy consumption?
• Do I need a low-glare inspection light for highly reflective surfaces?
• Do I prefer a lightweight strobe with soft but vibrant illumination?

New Unilux LED-Series 2000 Stroboscopic Inspection Lights Combine Green Tech and Traditional Power

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.

"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 users 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 times 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' light across a large rectangular area combined with focusing provided by the lenses creates an even, consistent lighting pattern across the target area. Customers will be able to inspect an area comparable to the xenon-based lights 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," he said. "The perceived light intensity seen by the user is actually a relationship between the intensity of light and the light duration. 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 a steel strip or printing 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').
