Abstract

Disclosed is a LED curing light device for curing of photo-polymerization materials. The device comprises of a plurality of LED source and a plurality of Fresnel lenses. The said LED source is powered and controlled by a drive board and batteries providing high power curing light in the range of 300 to 500 nm and optical power in the range of 100 to 800 mW. The said Fresnel lenses comprising a pair of Fresnel lenses couple said curing light efficiently to a focused spot on a curing object.
