Abstract
The present invention provides an arc lamp for producing a high intensity point source of light by magnetically compressing the light emitting element of the arc lamp. Arc lamp point light source 30 includes bulb 32 having two electrode 34, 36 spaced apart to have gap 35 therebetween and hermetically sealed within bulb envelope 44 filled with ionizing gas. Connector 46 is provided for applying a voltage potential across electrodes 34, 36 causing electric current to pass therebetween to generate arc plasma 42. Annular magnet 48 and bar magnet 50 located outboard of bulb envelope 44 generate a magnetic field around arc plasma 42 to compress the volume thereof between electrodes 34, 36.
