Abstract

PURPOSE:To secure such an illuminant that is capable of lighting plural lamps in a plate cavity at the same time and suitable for plane irradiation by specifying microwave input power per lamp unit volume. CONSTITUTION:Plural pieces of straight tube lamps 2 are set up in a plate type cavity 1. Inside the lamp 2, rare gas and various metals such as Hg, Cd, Zn, As or the like or these halides, iondine, deuterium, etc., are sealed therein. Since the lamp 2 is lighted by induced discharge of high frequency, these is unnecessary to install an electrode. Microwave power enters the cavity 1 from a microwave power source 6 through a wave guide 5 and a power supply port 4. This microwave power source 6 is magnetron of 2.45GHz in frequency and 12.24cm in wavelength, by way of example. In order to take light out, at least one surface of the cavity 1 consists in a wire gauge 3. With this constitution, plural pieces of lamps 2 are lighted simultaneously, and they can irradiate a plane surface, but the microwave power of more than 0.73w/cm<3> per lamp volume is required for this end.
