Abstract

Abstract The infrared source or light bulb is a halogen lamp and is connected to a control switch (28) supplying mains voltage at 100-240 volts. The bulb emits a light intensity of NOTLESS 750 cd, preferably NOTLESS 4000 cd. PREFERRED FEATURES:- The control switch (28) is a pressure switch which alternately turns the lamp on and off. The switch has no transformer and uses a thyristor or triac to supply a gradually increasing voltage on switching on the light source. The apparatus has a pistol form with an outer housing (18) which holds the dental compound and has a cable (12) from the lower end of the hand grip. The high voltage halogen lamp has contact pins or a screw thread for inserting into a socket connector (34). The lamp filament extends NOTLESS 2, preferably NOTLESS 4 cm and in side view is turned down to form a V-shape, in side view. An additional inner insulating housing covers the lamp socket and other voltage carrying parts.
