Abstract
A light-weight, portable photocuring device possesses a single 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. Lenses and/or light guides in the device act to further direct the light.
Claims23
A photopolymerization apparatus comprising:
- a housing;
- one light emitting diode;
