Abstract

The invention discloses a device for blocking air around an electrodeless lighting system, comprising: a waveguide having a shaft hole through which the bulb shaft can pass; a bulb motor mounted on the rear side of the waveguide And utilize the bulb shaft to be connected to the bulb arranged on the front side of the waveguide for turning the bulb; A sealed structure so that the surrounding air does not flow into the light emission area where the screen is located, and thus various impurities do not flow into the light emission area to ensure clean light emission conditions, which can reduce the oxidation of the screen, In addition, the stability of the lighting device can be improved, and the maintenance cost can be reduced.

Description

technical field [0001] The present invention relates to an electrodeless lighting system utilizing microwaves, and in particular to a device for blocking the air surrounding the electrodeless lighting system so as to prevent ambient air from flowing into the area where the bulbs and screens are installed. Background technique [0002] In general, an electrodeless lighting system is a device that emits visible light or ultraviolet light by emitting microwaves to an electrodeless plasma bulb, and it has a longer life and superior lighting effects than incandescent or fluorescent lamps. [0003] figure 1 is a longitudinal sectional view showing an electrodeless lighting system according to the prior art. [0004] A conventional electrodeless lighting system includes: a magnetron 2 installed in a casing 1 for generating microwaves; a high voltage generator 3 for providing high voltage to the magnetron after boosting the daily AC power supply to a high voltage; The waveguide 4 ...
