摘   要
 出租车在现在城市生活中扮演着重要作用，它给人们出行带来了很大的便利，同样它也代表着一座城市的形象。车顶灯是出租车的标志之一，如何清晰的把营运状态集成显示在车顶灯上将是未来车顶灯发展的一个方向。折叠式车顶灯提出来全新的折叠式结构。通过市场调查，了解乘客司机对原有车顶灯和折叠式车顶灯的意见，并做针对性设计和改进。本设计采用折叠式外壳，通过内部电动驱动四连杆机构，使其呈现打开和关闭的状态，代表空车和载客或者不在营运状态。本设计对车顶灯的电路做来重点设计，安装方便，无须重新布置车内饰电路，就可以将普通车顶灯更换为折叠式车顶灯，而且控制和普通车顶灯一样；同时，选用高亮度发光二极管作为光源，提高可靠性，增强亮度，延长使用寿命。该车顶灯将有效提高乘客对出租车营运状态的判断距离。本设计已经申请了国家实用新型专利，申请号为200920120918.4。

Abstract
 Nowadays, taxis play an important part in city life, which not only make it convenience for people to travel, but also act as the symbol of a city. Top light is one of taxi’s symbols. And its future development should be that how to show the work state of taxi clearly. The author will have a new design for folding-style top light. Therefore, firstly, the author tries to know drivers’ and passengers’ opinion to original design of top light by market research. Then, the author will make the relevant design and improvement according to the research. This design adopts folding –style shell. And with its inner four-bar structure drive by electric, the top light represents that the car is empty or has passengers, or not in the working state by making the top light open or close. The author pays much attention to the design of top light circuit, making sure that it is convenient to install, and there is no necessary to re-arrange the circuit before changing common top light into folding-style top light. What’s more, the control of folding-style top light is the same to common one. As to material, it would be light-emitting with high-brightness, which can improve reliability, enhance brightness, and extend operation life span. The top light has effectively shortened the distance that passengers need to judge working state of taxi. Besides, this design has already applied for national utility model patent, and the application number is 200920120918.4.
