Abstract
A source of actinic radiation for curing printing plates. The source includes a base with a heat sink and has a length greater than its width. One or more circuit boards mounted on the base provide a plurality of light emitting diodes (LEDs) distributed over the length of the base. A transparent or translucent cover together with the base defines an enclosure for the plurality of LEDs. The source provides the radiation at an emission angle greater than the emission angles of a single LED in a plane perpendicular to the axis of the base, in a plane containing the axis of the base or parallel to the axis of the base and perpendicular to the target illumination plane, or a combination thereof. The source may be configured to replace a fluorescent bulb. Methods and systems for bank exposure of printing plates using such sources are also described.
