Abstract
A light-weight, portable photocuring device possesses a single multi-wavelength light emitting diode (LED). The single LED backed with a heat sink is driven by a driving circuit and controlled by a timing circuit. A temperature monitor can be included in a closed loop to feed back and control the driver. A multi-plexing device regulates the current to individual ports on the LED effecting the dies allowing the overall wavelength and intensity of the emitted light by the apparatus to be controlled. Lenses and/or light guides in the device act to further direct the light.
