Abstract
The present invention relates to a short arc discharge lamp having a quartz envelope with a bulb and a support for supporting at least one electrode rod within the quartz envelope for specific alignment. The support includes a collar surrounding the at least one electrode rod and being made from a material having a melting point above an operating temperature of the short arc lamp. The collar also has at least one coil spring and at least one placement means for placing at least one coil spring around an outer surface of said collar. Connected to the support is a securing piece for securing the collar to the at least one electrode rod.

A short arc discharge lamp which comprises:
- (a) a quartz envelope having a bulbous portion;
- and
- (b) support means for supporting at least one electrode rod within said quartz envelope for specific alignment, said support means including:
- (i) a collar surrounding said at least one electrode rod and being made from a material having a melting point above an operating temperature of said short arc discharge lamp and having at least one placement means for placing at least one coil spring around an outer surface of said collar;
- (ii) said at least one coil spring surrounding said at least one placement means and contacting an inside surface of said envelop;
- and
- (iii) securing means for securing said collar to said at least one electrode rod.
A short arc discharge lamp which comprises:
- (a) a quartz envelope having a bulbous portion;
- (b) a plurality of electrodes spaced apart from one another within said envelope so as to create a short arc discharge space between them and within said bulbous portion;
- (c) an electrode rod connected to each of said electrodes and being within said discharge space;
- and
- (d) a support means for supporting said electrode rod within said quartz envelope for specific alignment including:
- (i) a collar surrounding said at least one electrode rod and being made from a material having a melting point above an operating temperature of said short arc discharge lamp and having at least one placement means for placing at least one coil spring around an outer surface of said collar;
- (ii) said at least one coil spring surrounding said at least one placement means and contacting an inside surface of said envelop;
- and
- (iii) securing means for securing said collar to said at least one electrode rod.
