Abstract

PURPOSE:To improve surface uniformity of lamp light output without using a part where an electric field in a cavity weakens by making thickness of the cavity connected to a microwave electric source of a light source device below 1/2 of wave length of a micro wave, and making distance between a side wall of the cavity and a lamp above 1/4 of wave length of the micro wave. CONSTITUTION:A cavity 1 is connected to a microwave electric source 6 of a light source device with a waveguide 5, and plural lamps 2 are arranged in the cavity 1. A microwave of prescribed wave length is generated by magnetron of the source 6, supplied to the cavity 1 from a power supply port 4 of a waveguide 5, and lamps 2 are lit by the microwave. And a metal net 3 taking out light to a surface of the cavity 1 is arranged, and plural lamps 2 are lit concurrently by the net 3. Thickness d of the cavity 1 is made below 1/2 of wave length of the microwave, sides a and b of the cavity 1 larger than an illuminated surface, lamps 2 apart distance e and f from sides a and b, and the distance e and f more than 1/4 of the wave length.
