Abstract

An enhanced LED (Light Emitting Diode) UV (Ultra Violet) polymerization device (10) suitable for being used for polymerizing resins, glues or inks applied on flat surfaces of panels, sheets, or coils made from wood or other materials, such as glass, plastic, metal, composite materials, paper, and cardboard, and on shaped surfaces of non-flat pieces made from wood or other materials, comprising a plurality of LEDs (16) of the UV type and wherein said LEDs (16) are organized into arrays or strings (17, 17′) arranged perpendicularly to or inclined with respect to the feeding direction of the piece to be submitted to polymerization, said arrays (17, 17′) of LEDs (16) being angularly orientable with respect to a horizontal plane either synchronously or independently to modify the radiation parameters of said LEDs (16), power level, distance from the panel or piece to be submitted to polymerization, and passage speed of the pieces being processed being equal.
