Abstract
Abstract A light hardening device is provided and includes a light source having a plurality of LEDs supplied by an electrical energy source, and a cooling device arranged upstream of the light source and operable to cool the light hardening device. The LED arrangement is disposed on a rear surface of a cooling body and the light hardening device has a connection in the manner of a halogen glow lamp. Also, a light source is provided having a plurality of LEDs, a cooling body on which the LEDs are mounted, and a connector element and an overall exterior geometry, each of which corresponds to the respective connector element and overall exterior geometry of a conventional reflecting halogen glow lamp having a rated voltage of 12 volts.
