摘   要
 出租車在現(xiàn)在城市生活中扮演著重要作用，它給人們出行帶來了很大的便利，同樣它也代表著一座城市的形象。車頂燈是出租車的標志之一，如何清晰的把營運狀態(tài)集成顯示在車頂燈上將是未來車頂燈發(fā)展的一個方向。折疊式車頂燈提出來全新的折疊式結(jié)構(gòu)。通過市場調(diào)查，了解乘客司機對原有車頂燈和折疊式車頂燈的意見，并做針對性設(shè)計和改進。本設(shè)計采用折疊式外殼，通過內(nèi)部電動驅(qū)動四連桿機構(gòu)，使其呈現(xiàn)打開和關(guān)閉的狀態(tài)，代表空車和載客或者不在營運狀態(tài)。本設(shè)計對車頂燈的電路做來重點設(shè)計，安裝方便，無須重新布置車內(nèi)飾電路，就可以將普通車頂燈更換為折疊式車頂燈，而且控制和普通車頂燈一樣；同時，選用高亮度發(fā)光二極管作為光源，提高可靠性，增強亮度，延長使用壽命。該車頂燈將有效提高乘客對出租車營運狀態(tài)的判斷距離。本設(shè)計已經(jīng)申請了國家實用新型專利，申請?zhí)枮?00920120918.4。

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.
