Abstract

PURPOSE: To attempt extreme enhancement of efficiency of a metal vapor discharge lamp with appropriate selection of kind of sealed gas for starting and sealed pressure.
CONSTITUTION: Enclose, for instance, Na I 30mg, Ti I 4mg, In I 1mg, Hg 70mg etc. into an illunication lamp made of guartz etc. provided with wolfram electric pole spread with thoria etc., together with Xenon or Krypton pressurized up to 100 Torr as starting gas. The efficiency may be remarkably improved, because convection becomes ectremely violent inside of the discharging lamp, owing to this contrivance.
