Abstract

This invention relates to a microwave no-electrode illuminating device which can prevent outside gas from flowing into a space with lamp and mesh including a waveguide tube, a lamp motor and a closed device, among which, the said waveguide tube has an axial hole for the lamp axis passing through, the lamp motor is mounted at the back of the waveguide tube by the axis so as to rotate the lamp, the said closed device is between the motor and the tube to block outside gas from flowing into the direction of the lamp to ensure a clean illumination condition.

Description

technical field [0001] The present invention relates to an electrodeless lighting device using microwaves, and further relates to an external air blocking device for the electrodeless lighting device that prevents outside air from flowing into a space where a bulb and a mesh screen are provided. Background technique [0002] Electrodeless lighting is a device that applies microwaves to electrodeless plasma (plasma) bulbs to emit visible light and ultraviolet rays. Compared with general incandescent or fluorescent lamps, the lamp has a longer life and better lighting effects. [0003] The electrodeless lighting device in the prior art will be described below with reference to the accompanying drawings. [0004] figure 1 A longitudinal section showing a prior art electrodeless lighting device. [0005] As shown in the figure, the prior art electrodeless lighting device generally includes a magnetron 2 , a high voltage generator 3 , a waveguide 4 , a mesh 6 and a bulb 5 . Th...
