Abstract:
A light beam hardening apparatus for hardening a material exposed to light emitted by the light beam hardening apparatus, comprising:a semi-conductor light emitting source operable to emit light in the visible light spectral range of a light strength of at least 200 mW/cm2, the semi-conductor light emitting source including a plurality of light emitting chips having a conductive substrate; a base receptacle for supporting the semi-conductor light emitting source base receptacle including a plurality of recessed cradles in the form of reflectors, each for supporting therein a respective one of the light emitting chips; a cooling body disposed adjacent the backside of the base receptacle, the cooling body having longitudinal ribs on its exterior for extracting heat therefrom; and a metallic heat conducting connection for each individual light emitting chip connecting the conductive substrate of each semi-conductor light emitting source to the base receptacle for conducting heat from the semi-conductor light emitting source to the base receptacle.
