【摘要】：LED照明殺菌燈是LED的最新應(yīng)用方向之一,論文對LED照明殺菌燈及其關(guān)鍵技術(shù)進行了研究,研制了一款LED照明殺菌燈,并成功應(yīng)用于家畜家禽養(yǎng)殖場室內(nèi)環(huán)境。論文的主要工作圍繞著照明殺菌燈的研制及其關(guān)鍵技術(shù)展開。 LED照明殺菌燈分為白光照明燈和紫外線殺菌燈兩部分。論文首先對白光和紫外線光源進行了研究；其次,根據(jù)LED照明殺菌燈的性能指標,研究確定了LED白光照明燈和紫外線殺菌燈的驅(qū)動電源方案,兩種驅(qū)動電源方案均采用開關(guān)電源作為拓撲結(jié)構(gòu),白光照明燈采用Buck拓撲結(jié)構(gòu),紫外線殺菌燈采用Flyback拓撲結(jié)構(gòu)；論文還對LED驅(qū)動電源的組成部分進行了設(shè)計,包括EMI濾波、功率因數(shù)校正、箝位保護電路、高頻變壓器、線性恒流源、反饋電路等,并對各部分的具體參數(shù)進行分析和計算。 論文制作了LED照明殺菌燈的驅(qū)動電源和LED照明殺菌燈的樣機。在實驗室對LED驅(qū)動電源的漏極電壓、輸出電壓和電流及其紋波等關(guān)鍵波形進行了測試和分析；在現(xiàn)場實際環(huán)境中進行了長期的試驗；驗證了方案的正確性。
[Abstract]:LED lighting germicidal lamp is one of the newest application directions of LED. This paper studies LED lighting germicidal lamp and its key technology, and develops a LED lighting germicidal lamp. It has been successfully applied to the indoor environment of livestock and poultry farms. The main work of this paper is focused on the development and key technology of lighting germicidal lamp. LED lighting bactericidal lamp is divided into white light lamp and ultraviolet bactericidal lamp. Firstly, the white light source and ultraviolet light source are studied in this paper. Secondly, according to the performance index of LED lighting bactericidal lamp, the driving power supply scheme of LED white light lamp and ultraviolet sterilization lamp is determined. Both drive power supply schemes adopt switching power supply as topology structure. The Buck topology was adopted for the white light lamp and the Flyback topology structure for the ultraviolet sterilization lamp. The paper also designs the components of LED driver power supply, including EMI filter, power factor correction, clamping protection circuit, high frequency transformer, linear constant current source, feedback circuit and so on. And the specific parameters of each part of the analysis and calculation. The driving power supply of LED lighting germicidal lamp and the prototype of LED lighting germicidal lamp are made in this paper. The drain voltage of the LED driving power supply is obtained in the laboratory. The key waveforms such as output voltage and current and their ripples are tested and analyzed. A long-term test was carried out in the actual field environment. The correctness of the scheme is verified.
