Title:
DISCHARGE LAMP, METHOD FOR PRODUCING DISCHARGE LAMP, AND ELECTRODE FOR DISCHARGE LAMP
Document Type and Number:
WIPO Patent Application WO/2015/033239
Kind Code:
A1
Abstract:
The objective of the present invention is to form electrodes with improved bonding strength in electrodes that are formed by solid-phase bonding a plurality of members. A cathode (20) comprising a distal end-side metal member (20A) and a rear end-side metal member (20B) is formed by solid-phase bonding and machining. On the tapered surface (20Q) of the cathode formed during machining, a grooved part (R) comprising fine grooves (r) and wide grooves formed by laser irradiation is formed so as to straddle the bonding surface (S1). At this time, machining is carried out in such a manner that scratches occur in the metal member (20B), but do not occur in the metal member (20A).
