Hamamatsu Corporation has introduced the LC-L5 (L11403 series), the latest addition to its Lightningcure series of UV spot light sources. Its characteristics make the LC-L5 an excellent solution for curing materials such as UV curing adhesives and coatings, as well as UV inks. The LC-L5 is a UV-LED light source that irradiates a linear area with monochromatic UV light at 365 nm or 385 nm (Â±5 nm). Two irradiation area sizes—105 x 10 mm and 305 x 10 mm—are available. The LC-L5 produces intense UV irradiation; LC-L5 models with 1000 mW/cm2 or 1200 mW/cm2 intensity are available. Because the LC-L5 is based on LED technology, it has some advantages over other types of UV spot light sources. Compared to bulkier UV light sources built with lamps, the LC-L5 is compact and lightweight for easy installation into tight spaces along a production line. It also has a long service life of 20,000 hours. In addition, the LC-L5 has low power consumption and minimal heat emission.
