【摘要】：微波等離子燈(Li ght Emi tting Plas ma)簡稱LEP,利用微波激發(fā)等離子體而發(fā)光,它是一種高效、節(jié)能、綠色、而且沒有電極的光源,是上世紀(jì)90年代出現(xiàn)的一種新型電光源。由于微波等離子體燈的熱光源發(fā)光特性,決定了它的光譜分布接近于太陽光譜,從而被國際公認(rèn)為一種高效節(jié)能的高品質(zhì)光源。微波等離子體燈的照明方案結(jié)合了系統(tǒng)可靠性,能源的利用效率,固態(tài)照明的控制系統(tǒng)和金屬鹵化物燈和高壓鈉燈的高流明輸出。根據(jù)微波等離子體燈的工作機(jī)制劃分,它可以分為兩代結(jié)構(gòu)。第一代的LEP由金屬網(wǎng)罩制成的諧振腔、波導(dǎo)系統(tǒng)、燈泡、電機(jī)以及磁控管等部分組成。第一代產(chǎn)品的工作原理導(dǎo)致了它會產(chǎn)生一些問題,比如利用電機(jī)使燈泡高速旋轉(zhuǎn)會導(dǎo)致系統(tǒng)不夠穩(wěn)定,燈泡在諧振腔內(nèi)不能完全封閉等一系列問題,使產(chǎn)品難以得到量產(chǎn)、推廣。第二代LEP取消了電機(jī),磁控管被固態(tài)微波射頻模塊替代,金屬波導(dǎo)系統(tǒng)和金屬諧振腔被介質(zhì)諧振腔替代,從而使系統(tǒng)的可靠性、燈的使用壽命都提高到很高的檔次,完全具備了商業(yè)量產(chǎn)、應(yīng)用的基本條件。本文用CST軟件對微波等離子體燈的主體部分——介質(zhì)諧振腔進(jìn)行了仿真,并利用ANSYS軟件對微波等離子體燈主體介質(zhì)諧振腔的設(shè)計(jì)進(jìn)行了熱分析,對為其提供能量的射頻模塊以及介質(zhì)諧振腔的優(yōu)化設(shè)計(jì)具有指導(dǎo)意義。我所做的主要工作可以分為以下幾個(gè)方面:1、研究了微波等離子體燈的工作原理和發(fā)光機(jī)理,在此基礎(chǔ)上對微波等離子體燈的主體部件——介質(zhì)諧振腔,進(jìn)行了設(shè)計(jì)和制作。2、利用CST對微波等離子體燈的主體部分——介質(zhì)諧振腔進(jìn)行了仿真分析。主要分析了介質(zhì)諧振腔內(nèi)部場分布及S參數(shù)。3、利用ANSYS對介質(zhì)諧振腔進(jìn)行了熱分析,為介質(zhì)諧振腔的優(yōu)化設(shè)計(jì)奠定了基礎(chǔ)。4、對介質(zhì)諧振腔的結(jié)構(gòu)進(jìn)行了優(yōu)化設(shè)計(jì)并對優(yōu)化改進(jìn)后的介質(zhì)諧振腔重新進(jìn)行分析,得到分析結(jié)果。
[Abstract]:Microwave plasma lamp (Li ght Emi tting Plasma) is a kind of high efficiency, energy saving, green and no electrode light source. It is a new type of electric light source which appeared in 1990s. The spectral distribution of microwave plasma lamp is close to that of the sun because of its luminescence characteristics, which is recognized as a high efficiency and energy saving high quality light source. The lighting scheme of microwave plasma lamp combines system reliability, energy efficiency, control system of solid state lighting and high lumen output of metal halide lamp and high pressure sodium lamp. According to the working mechanism of microwave plasma lamp, it can be divided into two generations. The first generation LEP consists of resonator, waveguide system, light bulb, motor and magnetron. The working principle of the first generation of products leads to some problems, such as the use of motor to make the light bulb rotate at high speed will lead to the instability of the system, the light bulb can not be completely closed in the resonator, and so on, which makes it difficult for the product to get mass production. Promotion. The second generation LEP cancels the motor, the magnetron is replaced by the solid-state microwave RF module, the metal waveguide system and the metal resonator are replaced by the dielectric resonator, so that the reliability of the system and the service life of the lamp are improved to a very high level. Complete with commercial production, application of the basic conditions. In this paper, the dielectric resonator, the main part of microwave plasma lamp, is simulated by CST software, and the design of the main dielectric resonator of microwave plasma lamp is analyzed by ANSYS software. It has guiding significance for the optimization design of RF module and dielectric resonator. The main work I have done can be divided into the following aspects: 1. The working principle and luminescence mechanism of microwave plasma lamp are studied. On this basis, the dielectric resonator, the main component of microwave plasma lamp, is studied. The dielectric resonator, which is the main part of microwave plasma lamp, is simulated and analyzed by CST. The field distribution and S parameter. 3 inside the dielectric resonator are mainly analyzed. The thermal analysis of the dielectric resonator is carried out by using ANSYS. It lays a foundation for the optimization design of dielectric resonator. The structure of dielectric resonator is optimized and the optimized and improved dielectric resonator is analyzed again, and the results are obtained.
