Research&Development Of Full Light Guide Headlamp Of Car

With the rapid development of automobile industry and the change of consumption conceptof Chinese people，Car sales industry is growing stronger. With the constantly emerging of thenew technology and new invention， many high-tech industrial products have also Around us inchina.However, car light as eyes of car, people hoped it both beautiful and good performance,light guide has the characteristics of beautiful and energy conservation and environmentalprotection, it can applied as new energy to the lamp inside by desiner.Production and application of optical technology is closely connected with the development ofthe LED，LED as a new type of light source within the automobile lamps in nearly a decaderapid development, With the wide applications of light guide in the market, the cost of LED alsogradually accepted for many car manufacturers, the application of the optical are common, basedon the LED application of new technologies, new products spring also emerge in endlessly.The lanterns lighting system of automobile lamps is original and directly，grandly develop to theindirect lighting, projection lighting, then develop to light guidel system.Compared with foreign industrial development, our country is still relatively backward, theapplication of key technology about light guide need ourselves continuously to explore, Opticaltechnology in the application of lamp is in the application of foreign brands is gradually to enterour field of vision, And the application of advanced technology is still with a layer ofmysterious,it made our domestic light industry had never seen them like the secret.Based on the research on a full light guide headlamp system development and trial of apassenger car, the main research contents this paper are summarized as follows:Understand the light guide of headlamp development status in domestic and aboard,,analyselight guide technology principle, explore and summarize the advantages and developmentprospects of guide light.Brief introduce theory of traditional optical and light guide technology,and exponent thestandanted of function signal of rearlamp in light regulations which is a constraints of light car. Described the basic methods and theories of basic distribution of light. It list early considerationsof light guide in detail about development and design. Brief introduction of the CAD/CAEsoftware application in all optical technology research.Research on the design and development of the light guide headlamp lighting system of apassenger car based on national standards, research on the application of CAD software forstructural design and CAE software for simulation optical and thermal analysis, and givevarieties solution of headlamp light distribution. Introduced in view of the optical lightdistribution pattern to the secondary development of software programs.Project and to carry on the design research and development, mold development, trialproduction, the optical verification and monitoring, heat by physical measurement resultscompared with the simulation data, and make products to meet regulatory requirements.Summarizes the light distribution design method based on optical tail lights, make a projectfor designing and developing the molds and prototype products. Make the test in the opticslaboratory and thermodynamic analysis. According to the development situation of LED andother light optical，we can predict the development of automobile industry and extend industry.The tooling sample the objective of had passed the car light distribution laws and regulations, itsnew modelling and optical effect have been conform for customers，and gave high evaluation。Through this project shows：the design method and simulation method of this article areeffective，also shows that through the application of a variety of software is not only save a lot ofdevelopment time but reduce the cost，more important is for the domestic automobile lamps andlanterns stepped out of the steps of the application of optical technology, accumulated valuableexperience.
