Patent ID: 7104793

Claim:
A light polymerization device, especially a light polymerization device for polymerizing dental material, comprising: a housing ( 12 ) provided with a hand grip; a light source ( 14 ) mounted within the housing ( 12 ) and which emits polymerizing radiation along an optical axis ( 76 ); means for creating a flow of cooling air which moves along a path generally transverse to the optical axis ( 76 ) of the light source ( 14 ), said means including an axial fan ( 26 ) mounted within the housing, the rotational axis or the fan being at right angles to the optical axis ( 76 ); and a cooling body ( 40 ) which is disposed in a selected one of direct heat conducting connection and indirect heat conducting connection with the light source ( 14 ) and which is provided with cooling ribs ( 46 ) impacted by the cooling air discharged by the fan ( 26 ), a portion of the fan being received in a receptacle in the cooling body.
