Low pressure gaseous discharge lamps — Part I

Radiation and conduction phenomena in low pressure gaseous discharge lamps are discussed in this paper. Results of measurements on the variables in a discharge are given, and an attempt is made to correlate them with the concentration of atoms at different energy levels, and with the luminous efficiency. An insight into the fundamental processes which occur in a gas discharge and govern the production of light in low pressure discharges are given. In Part I, which follows, radiation processes are discussed, and in Part II, scheduled for publication in the next issue, electrical conduction processes are covered.
