Study On The Automotive Interior Background Illumination System Based On LED Light Source

China’s economy continues to deepen development, people’s livingstandard continues to improving, the development of the automotive industry isleaps and bounds With the continuous development of the automotive industry,market competition is increasingly fierce, the design of the vehicle has enteredthe era of diversified and personalize.Vehicle interior design is the same, in order to fit the vehicle design style,each main car interior also formed his own style.As the interior design is veryimportant elements: background lighting system design, have introduced moreand more requirements and new elements. So the deep research andstandardization of background illumination system are of great significance.Tolerance need to be considered at every engineering design, design ofbackground illumination system is the same. The definition of brightnesstolerance for design and production has a very important significance.At present, we both at home and abroad for car interior backgroundlighting system brightness tolerance definition is very simple, general, such atolerance system, for the definition of tolerance, tolerance is very difficult to define, a strict tolerance will lead to the increase of production cost or increasethe scrap supply, even more serious can lead to production line stop. Tolerancedefinition too loose can lead to the final product quality can’t control.Immethodical tolerance system, will cause the same tolerance, on differentoccasions have severe or too loose situation. Like a center console on a car thebackground illumination brightness differ, some dazzling some difficult todistinguish, so influenced both beautiful and affect the quality of the vehicle,and may even affect to safety. So formulate a set of perfect tolerance system isof important significance.This article through to the vehicle interior background lighting system athome and abroad of tolerance analysis research, combining the actual userexperience, present defects and insufficiency of mainstream manufacturers athome and abroad in the background lighting system tolerance definition, andanalyze and research the possible background lighting tolerance, this paper putsforward a set of not only conforms to the actual production and can meet thequality and customer demand brightness tolerance system.In the study, the author of a large number of experimental data statistics,analysis and research for the illumination system in each part of the tolerance,finally obtained the comprehensive interior backlight system practical tolerancesystem.And then, combined with the human eye brightness internationalrecognition results, according to the author puts forward a new brightnesstolerance system, formulate a set of feasible can be used for vehicle backlighting system brightness tolerance value.At the same time to the futureof interior lighting design puts forward his own ideas.
