摘要现阶段人类采集能源的主要方式是利用煤炭、石油、天然气等资源，而这些资源具有不可再生性，导致人类社会面临着巨大的能源危机。而清洁无污染并且可循环利用的太阳能恰恰能解决这样的问题，所以人们的目光越来越多的聚焦在这种还未得到充分利用的能源上。

照明能耗一直是建筑能耗中比较多的一项，在有关数据中显示照明能耗一直占建筑总能耗的30%左右。所以如果能够将太阳光引入室内提供照明，不仅能够大大的节省能源的消耗，同时能让人在室内也能够享受到太阳光的照明，对人的健康也有一定的好处。对设计的太阳自然光照明系统进行了研究，归纳其由采光系统、光传输系统、照明系统三部分组成，并对这三个部分进行了详细的介绍和分析。对采光系统部分的研究中，通过列举三种常见的聚光装置，并比较他们各自的特点和优缺点，从而选出了我们符合我们要求的菲涅尔透镜作为聚光装置。
对光传输系统的介绍中，通过对各种传光装置的比较，决定采用传光损耗小，传光距离远并且造价低廉的塑料光纤。9739
对照明系统的研究，通过资料的收集最终确定利用散射效果较好的平凹镜作为散射照明装置。

毕业设计说明书（论文）外文摘要
At present people gather energy mainly by the way of utilization of resources such as coal,oil and gas,and the mineral resource is a special material which has special features as non-renewable,causing the human society is facing a huge energy crisis.
As a clean, non-polluting energy, solar energy has recycled and inexhaustible characteristics,so the vision of people has increasingly focused on the energy which still haven't taken full advantage of it yet.
In the relevant data to show in the energy consumption of building lighting has been about 30% of the total energy consumption.
So if you could introduce the sunlight indoor and supply lighting,can not only greatly save energy consumption, also can let a person be in indoor can also enjoy to the sun lighting,to the health of people also have certain benefits.
To design of the sun natural light lighting system,sums up the lighting system by, optical transmission system, lighting system of three parts, and also detailed introduction and analysis.
Part of the system of daylighting study, through the listed three common focusing device, and compare their respective characteristics and advantages and disadvantages, so we meet our requirements that chose the Fresnel lens as focusing device.
The introduction of the optical transmission systems, through the comparison of various light device, decided to use the small loss light, the light of distance and cheap plastic optical fiber.
The study of lighting system, through the collection of data eventually determine to chose the Flat concave mirror which has better dispersion effect as the scattering lighting devices.
Keyword：Sun natural lighting system;Fresnel lens;Optical fiber;Fiber Optic cable;Flat concave mirror.
