Abstract
A hand held dental instrument for curing light-curable compounds including a housing with a handle portion and a barrel portion configured for being manipulated for positioning a tip end of the barrel portion proximate to a curing site. A plurality of solid state, light-emitting elements are mounted in a collective array to collectively form a beam of light. The array of elements is operable for collectively emitting a beam of light having wavelengths within a band of wavelengths and at a power to cure a dental compound. The array of elements is positioned proximate to the tip end of the barrel portion and the emitted light beam from the array illuminating a curing site. A radiation focusing device is positioned proximate the array of elements at the tip end of the barrel portion to focus the beam of light before it illuminates the curing site.
