The BlueWave LED visible light, high-intensity spot-curing system from Dymax Corp. is said to offer advantages over traditional UV spot-curing systems including no bulbs to change, cool cures, no warm-up, and constant intensity for thousands of hours. The system generates light using an array of surface mount LEDs
(light emitting diodes) instead of traditional metal halide or mercury bulbs. The LEDs produce visible light energy in a relatively narrow wavelength band centered at 410 nm, as contrasted to a typical broad-band, high-pressure UV bulb (300-500 nm). This system emits a maximum visible-light intensity output of more than 2,500 mW/cm2
from an 8 mm diameter lightguide, and allows users to adjust intensity output from 0 - 100%. The relatively narrow band produced by LEDs generates cooler curing temperatures. According to the manufacturer, the system is excellent for spot curing of coatings, as well as adhesive bonding of polycarbonate, PVC, PET, metal, glass and many other substrates.
