Unilux wins LED industry award for new strobe design
Saddle Brook, NJ-based Unilux, Inc. which designs strobe lights for inspection has won the 2017 Sapphire Specialty Design Award for its industry-first LED UV strobes used to inspect optical brighteners in banknote and secure document printing and coal seal applications in flexible packaging.
Unilux says that using LEDs in place of a combined xenon light source and filter eliminates the filter penalty. The penalty was the result of using the filter to remove visible wavelengths of light, thereby reducing the strobe light’s over-all efficiency. Using LED’s increases the amount of power used to generate light in the UV spectrum thereby making these strobes more powerful and efficient than non-strobe counterparts.
As well, the brighter light lets inspectors see details in the UV portion under ambient light, something they couldn’t do before, says Unilux.
Unilux inspection lights use the stroboscopic effect to freeze images of sections of webs moving at full production speed, making the smallest of defects clearly visible. This enables operators to use their knowledge of the product and printing process to determine the cause of the defect, take appropriate action to fix the problem or stop expensive, value-added processes, and reduce waste.
