<p>This invention relates to a curing light device suitable for curing light curable dental composite material. The device comprises a housing having a substantially hollow interior, a distal end, a proximal end, with the portion of which that is towards the distal end serving also as a handle. A light module is housed in a desirable position in the interior of the housing, and comprises at least one light source, at least one reflector to direct and/or focus the light from the light source, and at least one heat sink located in the proximity of the light source to divert heat away from the light source. The reflector and portions of the housing to which the reflector is attached have the same or substantially the same coefficient of thermal expansion.</p> |
