[Abstract]:The research content of this paper is the sub project of the industrial research and research cooperation program of Shanghai City, the industrial research and development of the all LED combination headlamp industrialization (number: Shanghai CXY-2013-39). The headlamp is one of the important parts of the automobile. Its design is not only related to the beautiful appearance, but also the more important is the direct driving safety. Compared with the traditional lighting source, LED light is compared. The source has the advantages of long life, low power consumption, small volume, small volume, quick response, flexible design and flexible control. Especially, the installation depth of LED lamps is shallow, and more space.LED can be used in the vehicle to make it possible to realize the concept of road safe and comfortable lighting by changing the light type. With the white light LED Technology Continuous progress and higher requirements for energy saving and environmental protection products, the use of LED headlights continuously increasing, its large-scale application in automotive lighting has become an inevitable trend. In the car headlamp market, the current domestic automotive lamps suppliers do not have the technology of independent research and development design and mass production of all LED combined headlights. However, as a trend, the combination technology that will be used in the next generation of automotive headlights can only be developed on the basis of the ability to design LED far and near light lamps. The new intelligent headlamp system using LED light source overcomes the shortcomings of traditional mechanical adjustment life, easy to damage and so on, and realize the change of light distribution through arrangement. The future intelligent headlamp system is bound to be more popular with designers and consumers because of its more flexible and more humane characteristics. On the basis of the research on the development of automobile lighting at home and abroad, this paper has designed a LED far and near light integrated headlamp, which mainly includes the demand for universal, practical and quantitative production in the production practice. The optical system design, the basic radiator, the exterior design and the main work are as follows: 1. through the development of the Chinese semiconductor industry, the history of the development of the headlights and the current situation of the automobile light industry, the value of this study is put forward. The main points of this paper are put forward through the analysis of the appearance and development trend of the LED headlights at home and abroad. In order to study content.2., this paper focuses on the design of LED far and near light integrated lamp with the advantage of LED, to improve the utilization rate of light energy as high as possible under the premise of meeting the standard of far and near light distribution light, design as simplex as possible, miniaturized, suitable for the headlamp of more vehicles in industrial production by analyzing the needs of the common optical system of LED. With the present situation, the design of the optical system is put forward. The scheme completely relies on the free surface reflector to match the light, and realizes the far and near light distribution under the small reflector by the zoning of the reflector. To a great extent, the installation space of the headlamp is saved. According to the national standard of the LED headlamp for the GB 25991-2010< automobile, the application of the light is used. The design software LucidShape and the 3D design software CREO have simulated the reflector of the light in the far and near light integration and the simple heat dissipation design and the exterior design. The car headlights designed in this paper have the following innovation points: 1. compared with the multi LED headlights, the structure is compact and the general halogen light consumption is 55W, The power consumption of the LED near light lamp in this paper is only 2.4W, which is used for the future pure electric vehicle. It has obvious energy saving advantage.2. and the low cost.3. overall structure of the mold is only 100mm* 110mm compared with the LED independent design of the light lamp / light lamp. The combination value of the far and near light size is only equivalent to the traditional one. The size (GB T 4659-84< headlamp type, main size and connection size >), compared with the traditional headlights, it is beneficial to the streamline design of the car body. The design of the radiator and the overall high cutting degree, the overall design is simple and beautiful, and the model is highly applicable.
