摘要:随着我国城市化进程的加快,发展效率高、能耗低且环保清洁的新型路灯逐渐成为城市建设者研究的重要课题。本文针对传统路灯效率低、能耗高的问题设计了一种太阳能LED路灯。该路灯主要由太阳能电池组件、蓄电池、LED路灯、控制器这几个部分组成。文中对路灯组件进行了选型,设计了以单片机为核心的路灯控制器,最后通过C语言编程实现对太阳能LED路灯的自动控制,使其能够自动工作。本设计的实现可广泛应用于城市主干道、小区、工厂、停车场等地区,对我国路灯的发展将有很大的现实意义。66445

Abstract:With the acceleration of urbanization process in our country, it has become an important subject to develop a new-style streetlight for city builders, which has high efficiency, low energy consumption and environmental cleaning. In this paper, we design a solar LED lights to solve some problems in traditional streetlights, like low efficiency and high energy consumption. The streetlight mainly consists of four parts: solar cell, batteries, LED streetlights and controller. Firstly we make choice on the streetlight module, secondly using microcontroller as the core of the lighting controller, in the end, realizing the solar LED lights automatically controlled by the C programming language, so that it can work automatically. If the design is applied, it can be widely used in urban roads, housing estate, factory, car parking and other areas. Last but not least, it must have a great practical significance to develop the streetlight in our country.
