Abstract

A dental curing light (100) includes a body (102), one or more LEDs (108) configured to emit a first spectrum of light having a relatively short first peak wavelength (e.g., UV) disposed on the body, and a fluorescing lens (110) that converts at least a portion of the first spectrum of light into a second spectrum of light having a second peak wavelength that is longer than the first peak wavelength. The second spectrum of light is selected so as to match the curing spectrum of a desired light-curable dental composition. In a preferred embodiment, the body (102) comprises an elongate wand having a proximal end (104) and distal end (106). The LEDs (108) may be disposed at or near the distal end (106) of the elongate wand.
