Using bicylindrical shape metal outer conductor in following Examples, lower 3 internal diameter of cylindrical outer is φ 35mm, length
For 38mm, 4 internal diameter of upper cylindrical outer is φ 18mm, and length 10mm, 5 outer diameter of magnetron antenna is 15.2mm, coaxial humorous
The chamber operational input impedance that shakes is about 50 Ω.Experimental result using same bi-conical metal outer conductor is also almost the same.
Example 1：
Using the cylindrical quartz light bulb 1 of internal diameter φ 10mm, a length of 30mm, it is filled with the selenium of 9mg, the xenon of 30KPa, coaxial humorous
The chamber that shakes is provided with the microwave power excitation of 250W, and emission spectrum output is as shown in Figure 3.As can be seen from Figure 3 the spectrum is continuous

Gas is encouraged in coaxial resonant cavity with 250W microwave powers, as shown in fig. 7, light efficiency is 90lm/W, colour rendering index is for spectrum output
81.2, correlated colour temperature 6108K.Compared with Fig. 5, only start gas argon gas has been changed by xenon, at this moment light efficiency under
Drop.It finds that xenon participates in shining in an experiment, xenon is added and helps to improve light efficiency, it is big that xenon is generally added in practical operation
In 10KPa.
Example 6：
The cylindrical quartz light bulb 1 for using internal diameter to be 40mm for φ 10mm, length is filled with 8.1mg selenium, 0.9mg telluriums and 30KPa xenons
Gas, under coaxial resonant cavity input 250W microwave powers effect, the spectrum measured is as shown in figure 8, equally find out that spectrum is apparent
Purple light direction is shifted to, light efficiency 46lm/W, colour rendering index 83.4, correlated colour temperature 10206K, it is microwave work(that can calculate this
Rate density is 110W/cm3.Obviously, it is relatively low to be added in Microwave Power Density in coaxial resonant cavity.
Experiment shows to act on electrodeless bulb Microwave Power Density 130-140 W/cm3It is advisable.
