Microwave sulfur lamp

Abstract

The invention makes public a kind of microwave sulfur lamp, includes the relativistic magnetron that produces microwave energy under the electric power action in the inside of the machine's cover; the wave-guide cavity transmits the microwave to the resonant cavity that can make the microwave energy syntonic, the quartz bulb that is designed in the resonant cavity can emit light through the stimulation of microwave energy, the bulb motor that drives the quartz bulb turning; the resonant cavity comprises of metal reflector and interlayer glass. The efficient effect is: since the new microwave resonnant cavity that is made up of the interlayer glass and metal reflector, which improves the coupling competency of the microwave energy and light resource, and then improves the light efficiency, increases the performance of making the light go through, saves the energy source, in addition, the interlayer glass and metal reflector can also make the performance of the microwave shield increase, the new microwave resonant cavity can lessen the volume of the metal reflector in accordance with the practical need, and then make the structure more compact, then reduces the production cost of microwave sulfur lamp; the interlayer glass do also have the effect of good property to prevent dizzy light, and then improve the whole service lifespan of microwave sulfur lamp.

Description

technical field [0001] The invention relates to a microwave sulfur lamp with a novel microwave resonant cavity. Background technique [0002] The current microwave sulfur lamp has a structure as shown in Figure 1, including a magnetron 1, a rectangular waveguide cavity 3, a resonant cavity 4, a quartz bulb 5 and a bulb motor 8; The microwave 2 is generated, and the microwave is transmitted to the resonant cavity 4 through the coupling hole of the rectangular waveguide cavity 3, and the microwave is coupled with the sulfur plasma contained in the quartz bulb 5 in the resonant cavity to excite sulfur molecule radiation, which excites the quartz bulb 5 to emit light, and is emitted by the The metal reflector 6 reflects the light, and the top of the metal reflector 6 is closed with a glass lampshade 7; in order to make the plasma work uniformly and stably, the quartz bulb is driven by a motor to rotate at a high speed. The disadvantages of the above-mentioned existing microwave...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned existing microwave sulfur lamps are: the microwave resonant cavity adopts a metal mesh structure, and the metal mesh cover has a standard size, so the size of the lampshade is limited, and the lampshade cannot be too small, which is not conducive to the small size of the overall microwave sulfur lamp. The light transmission of the resonant cavity is poor, and the light source will lose part of the light source when passing through the resonant cavity; the resonant cavity is also the main reason affecting the service life of the microwave sulfur lamp, so the service life of the overall microwave sulfur lamp is reduced
