论文编号:WLX138  字数:10796,页数:22  附任务书,文献综述,开题报告,外文翻译等亮度可调色温LED台灯研究摘     要: 白光LED具有发光效率高、功耗低、寿命长、环保等很多其它传统照明光源无法比拟的优势。因此被认为是取代白炽灯跟荧光灯最具潜力的照明光源。本文根据目前半导体照明的最新研究进展,介绍了GaN基白光LED应用在室内照明领域的可行性以及发展趋势。本文也从视觉指标、光学参数、封装技术、价格等方面出发,指出了白光LED在日常照明普及过程中以及可调色温LED台灯应用的一些主要问题,并对这些问题做了详细的分析与探讨。针对现有可行的解决方法,对发展前景做了进一步展望。这样,可调色温的台灯的研究也越显得大势所趋。关键词:白光LED  日常照明  可调色温  LED台灯Study on equal brightness and adjustable color temperature LED lampAbstract The white LED has the advantage of high luminous efficiency, low power consumption, long life, environmental protection.  The other traditional lighting sources can not match the above advantages. Therefore the white LED is considered to replace incandescent and fluorescent lighting.  In this paper, semiconductor lighting source, based on the current progress of the latest research, is introduced in indoor application of GaN-based white LED lighting. After discussing the visual indicators, optical parameters, packaging technology, the cost, this article also points out that the white LED lighting in the day-to-day popularity of the course as well as color temperature adjustable LED lamp applications, some of the main issues, and these issues and has done a detailed analysis and discussion. Then, existing and possible solution, development prospects of further prospects. In this way, equal brightness and adjustable color temperature table lamp study the more general trend Keywords: white LED; ordinary lighting; equal brightness and adjustable color temperature; LED table lamp目  录中文摘要 2英文摘要 3目录 4第一章     绪论  5 1.1  研究动机与目的 5 1.2  研究背景与前景 5 1.3  研究方法与系统阐述 6 1.4  论文热莞攀 7第二章    普通照明在与LED照明对比下的不足与弊端  10 2.1  普通照明台灯的应用方面的不足 10 2.2  通过说明LED的可调色温对问题的解决以及对使用者带来的益处 10第三章    LED色温控制原理以及LED匹配电源的研究 12 3.1   LED的色温控制原理 12 3.2   LED匹配电源的研究与探讨 12第四章    符合要求的电路设计和实验测试 16      4.1  对电路进行诠释分析电路的合理性 16      4.2  黄光的LED的参数测试 17第五章    两种可调色温LED台灯设计 18第六章    结论 20致谢 21参考文献 22
