一种手摇发电夜照灯的设计与有限元分析
摘 要：在现在的社会当中人们已经离不开灯光的照明。在以前正是人们对生产生活等方面的迫切需求，人
们为了用更长的时间去工作为了养活家人，从而人们开始对光的追求。在现在社会的急速发展和科技的迅
速的提高，比如在灯光方面；正是因为灯光的广泛运用，造就了许多的不夜城，这也造成了在自然资源的
疯狂消耗。正是人们对天然资源的掠夺式的开发也造成了社会能源危机。在本文当中，我们就设计了一款
可以通过手摇从而发电的便携夜照灯。我们都知道，市场上传统夜照灯都是通过干电池或者外接充电器充
电的供电方式，这两种以前老式的夜照灯不仅其综合利用效率低，内部电池如果处理不好还对会环境造成
污染。现如今的人们提倡绿色环保和资源可持续利用，正因如此他们需要一款不用充电的夜照灯，所以为
了应对市场的需求，我们为此设计一款通过可以通过手摇发电的夜照小灯，从此让人们告别电池和充电困
扰。

Design of a Hand Operated Night Light
Abstract; In today's society, people can not do without lighting. In the past, it was people's urgent need for
production and life. In order to work longer and support their families, people began to pursue light. In today's rapid
development of society and rapid improvement of science and technology, such as in lighting; It is because of the
wide use of lighting, creating a lot of never night city, which also caused the crazy consumption of natural resources.
It is people's plundering development of natural resources that also causes social energy crisis. In this paper, we
designed a portable night light which can generate electricity by hand. We all know that the traditional night lights
on the market are powered by dry batteries or external chargers. These two old night lights not only have low
comprehensive utilization efficiency, but also cause environmental pollution if the internal batteries are not handled
properly. Nowadays, people advocate green environmental protection and sustainable utilization of resources.
Because of this, they need a night light that does not need to be recharged. Therefore, in order to meet the demand
of the market, we design a night light that can generate electricity by hand, so that people can say goodbye to the
battery and charging problems.
Key words: Night light; Hand power generation; environment protection
