I claim:
1. In a light source, the combination comprising,
- a. an envelope
- b. means including an electrical power source and electrode structure connected therewith to produce light at a zone within the envelope, electrode metal becoming vaporized in said zone, said source producing electrical pulses and said electrode structure comprising spaced electrodes between which a pulsed arc is produced at said zone by said electrical pulses,
- c. light conducting rod means terminally facing within the envelope toward said zone, and
- d. said source including means to control application of voltage to the electrode structure and the repetition rate of said pulses, in relation to the closeness of the rod terminal to said zone, so that the rod terminal remains at temperatures below melting temperature but high enough to prevent vaporized metal deposition thereon during said pulsed arc production.
