Abstract
A dental curing light system is configured to include a dental curing light (100) having a device body (102) with a proximal handle portion (106) and a distal head portion (104). One or more light sources (120) for generating light are disposed on or within the device body (102). Generated light is emitted from the distal head portion (104) and includes wavelengths greater than about 420 nm and wavelengths less than 420 nm. A separate head attachment member or device (160) is coupleable over the distal head (110) of the device body (102) so as to receive substantially all light emitted from the distal head portion (104) of the device body (102).

A dental curing light system, comprising:
- a dental curing light device comprising:
- a device body having a proximal handle portion and a distal head portion from which light is emitted during use;
- and
- one or more light sources disposed on or within the device body and that are configured for generating light that includes wavelengths of light greater than about 420 nm and wavelengths of light less than about 420 nm;
- and
- a head attachment member coupleable to the distal head portion of the device body and configured so as to receive substantially all light emitted from the distal head portion of the device body,
