【摘要】：目前,人类使用的主要能源(煤、石油、天然气等)都为不可再生资源,其储量有限。随着现代社会电气自动化的日益发展,人们对能源的需求越来越多,节能减排的呼声也越来越高。照明占整个能源消耗中的四分之一,减少照明能耗已成为社会发展中一个需要解决的突出问题,已经引起全球范围内的热切关注。本文主要研究照明光源,特别是LED照明灯具。本论文包括以下内容:1.介绍了光源从火、油到电的发展历程;灯从火把、各种油灯、白炽灯、日光灯,直到现在多彩缤纷的装饰灯、节能灯的发展过程;以及各种光源——白炽灯,荧光灯,高压纳灯等的性能和应用特点。2.总结了LED光源的特点,主要包括:发光原理、可见光谱、白光的实现方式。发光器件的光电参数:光通量、发光强度、光照度、光亮度、相对光谱能量(功率)分布、峰值发射波长、光谱半波宽、LED色度学参数。3.分析了LED作为一种新型光源的发展过程、分类,及存在的问题——散热问题、性能不稳定、价格较高;分析了LED的特点:体积小、重量轻、寿命长、功耗低、反应速度快、发光效率高等;分析了LED电源的驱动要求及电源选择;分析了LED灯具的发展现状,发展趋势。4.在Tracepro中建立LED模型,并使用这种模型对常见的几种LED阵列排布进行分析,通过仿真模拟,使其达到了较好的光照均匀度。5.研究室内照明亮度,均匀度,配光曲线等需求,根据室内照明需求分析设计LED室内照明灯具,在配光和照度均匀度方面进行优化,得到具有矩形光照效果的LED“蝙蝠翼”形配光,并与荧光灯进行对比,分析其与传统灯具相比存在的优势。
[Abstract]:At present, the main sources of energy (coal, oil, natural gas, etc.) are non-renewable resources, and their reserves are limited. With the development of electric automation in modern society, the demand for energy is increasing, and the voice of energy saving and emission reduction is becoming higher and higher. Lighting accounts for 1/4 of the total energy consumption. Reducing lighting energy consumption has become a prominent problem in the social development, which has attracted worldwide attention. This article mainly studies the illumination light source, especially the LED lighting lamp. This thesis includes the following contents: 1. This paper introduces the development of light source from fire, oil to electricity, and the development of lamps from torches, oil lamps, incandescent lamps, fluorescent lamps, and colorful decorative lamps and energy saving lamps. As well as various light sources-incandescent lamp, fluorescent lamp, high-voltage nano lamp and so on performance and application characteristic. 2. The characteristics of LED light source are summarized, including the principle of luminescence, visible spectrum and the realization of white light. Optoelectronic parameters: luminous flux, luminous intensity, luminance, relative spectral energy (power) distribution, peak emission wavelength, spectral half-wave width, LED chromaticity parameters. 3. The development process, classification and existing problems of LED as a new type of light source are analyzed, such as heat dissipation, unstable performance and high price. The characteristics of LED are analyzed, such as small volume, light weight, long life, low power consumption, fast reaction speed, high luminous efficiency, etc. The driving requirements and power selection of LED power supply are analyzed, and the present situation and development trend of LED lamps and lanterns are analyzed. 4. The LED model is established in Tracepro, and the common LED array arrangement is analyzed by using this model. The simulation results show that the model achieves better illumination uniformity. The luminance, uniformity and distribution curve of indoor lighting are studied. According to the analysis of indoor lighting requirements, the LED indoor lighting lamps are designed and optimized in the aspects of light distribution and illumination uniformity. The LED "bat wing" light distribution with rectangular illumination effect was obtained, and compared with the fluorescent lamp, the advantages of the bat wing compared with the traditional lamps were analyzed.
