Abstract:
1. A light-emitting device comprising: a translucent cover, a light-emitting diode (LED) enclosed in said translucent cover, and electrode means electrically connected to said LED, wherein said light-emitting device is in such a compact size as to be disposed in a dental handpiece, characterized in that said electrode means comprises: a cathode terminal generally in the form of a cylinder having first and second ends and having an opening at each of said ends, and an anode terminal generally in the form of a pin having first and second ends and arranged concentrically in said cathode terminal, wherein said cathode terminal and said anode terminal are arranged concentrically with said LED with the first ends of the cathode and anode terminals in electrical connection with said LED, wherein said opening at the second end of said cathode terminal exposes the second ends of the cathode and anode terminals for electrical connection to an external socket, and wherein said concentrically arranged cathode and anode terminals form an annular space therebetween in said second ends, said space receiving corresponding terminals of said external socket for said electrical connection.
