Abstract (en)
[origin: EP0964429A1] This is an electron emission electrode structure that can shorten the transition time from glow discharge to arc discharge and, at the same time, stabilise the arc discharge and prevent reduction of electrode life and blackening of the tube inner wall, together with a discharge lamp that uses this electrode structure and a discharge lamp device in which this discharge lamp is installed. It is electron emission electrode structure 3A that is composed of electron emitter 5, made of an aggregate of granules 51, ..., that emits thermal electrons from an exposed surface when heated by a discharge, and a discharge focussing means that is in the close vicinity of, or in contact with, the above exposed surface of electron emitter 5 and focuses the discharge on the above exposed surface, together with discharge lamp 1 that uses electrode structure 3A and discharge lamp device 9 in which discharge lamp 1 is installed. <IMAGE>
