Claims

[Claims for Utility Model Registration] (1) A heater transformer whose secondary side is connected to the heater of a magnetron, an input power source connected to the primary side of the heater transformer via a power switch,
an excitation valve that receives power from between the power switch and the primary side of the heater transformer via an excitation switch to excite the arc tube; and a high voltage switch that is connected between the power switch and the primary side of the heater transformer. and a high voltage transformer that receives power supply through the magnetron and applies high voltage to the magnetron, and when the power switch is turned on, the excitation switch is on, and the first
Turn on the high pressure switch after a period of time has elapsed, turn off the excitation switch after a second period of time has elapsed since the high pressure switch was turned on, and turn on the excitation switch in conjunction with turning off the high pressure switch. What is claimed is: 1. A microwave electrodeless light emitting device characterized by being provided with a controller for controlling. (2) The microwave electrodeless light-emitting device according to claim 1, further comprising means for integrating the on-time of the power switch and/or the on-time of the high-voltage switch. (3) Claims 1 or 2 for registration of a utility model, characterized in that an optical sensor for detecting the luminescence of the arc tube is provided, and a means for integrating the luminescence time detected by the optical sensor is provided. Microwave electrodeless light emitting device as described in .
