Abstract:

A description of the carbon vapor lamp, inclusive of experiments performed for improvement of the high-intensity carbon arc as a thermal radiation source is given. Potential improvements in the latter are cited in order of importance 1 stability, 2 control, and 3 simplicity. The carbon electrode consumption is greatly reduced by operation in a partial vacuum. Use of a-c power results in the elimination of the d-c power rectifier. Photographs of the three-phase a-c carbon vapor lamp are shown. Author
