The development of electric lighting source industry puts a higher demand on lighting gases.

Fault analysis of high power gas discharge lamp;

Gas discharges of barium,cluster,hydroxyl and fullerene were introduced,and the probability of these four emitters'application in gas discharge lamps was discussed.

Using the gas discharge lamp as the light source of atmospheric optical communication,the function theory and characteristic of this light source are analyzed.

It is showed that the acoustic resonance phenomena would happen in high intensity discharge lamps working in high frequencies with appropriate exciting frequencies and enough energies at the same time.

Study on Electronic Ballasting Techniques for High Intensity Discharge Lamp;

This paper has introduced that structure of inductance ballast of the gas discharge lamp and structure and performance of electronic ballast, has given some examples for applying the electronic ballast and has compared parameter change and light efficiency of inductance ballast with which of electronic ballast when voltage of electric power net changes.
