论文题目：汽车前照灯的检测与驾驶安全 摘要 前照灯是汽车在夜间或在能见度较低的条件下，为驾驶员提供行车道路照明的重要设备，而且也是驾驶员发出警示、进行联络的灯光信号装置。所以前照灯必须有足够的发光强度和正确的照射方向，发光强度、照射方向发生变化，都会使驾驶员对前方道路辨认不清，或在与对面来车交会时造成对方驾驶员炫目等，从而导致事故的发生。汽车前照灯检测，是汽车检测站对车辆安全性能和综合性能检测评价的一个重要项目，主要是检测前照灯的发光强度和照射方向是否达到国家标准，以确保车辆在夜间或视觉条件不良情况下的运行安全。汽车前照灯直接关系到行车安全。以内藏式前照灯、自动变光、自动开灯和延时关灯等为代表的新结构和控制方式对汽车整体性能的提高起到了巨大作用。研究新型前照灯的检修方法非常重要，本文说明了前照灯的检修方法、步骤及原理。 关键词：前照灯，自动控制，检修，灯光开关，继电器，放大器 Abstract Car headlamp is at night or in low visibility condition, provides for the drivers driving road lighting equipment, but also the important drivers issued warnings, contact the light signal devices. So the headlamps must have enough light intensity and the correct exposure direction, the luminous intensity, illuminate direction changes, will allow the driver to make clear, the road ahead with opposite to car or cause other drivers glaring resection, causing accidents. Cars headlamps detection of vehicle and vehicle testing is safe performance and comprehensive performance test and evaluation of the project, the main is an important test headlamp luminous intensity and illuminate direction is to ensure that meet the national standards, the vehicle in the night or visual conditions under the circumstance of poor safety operation. Car headlamp is directly related to the safety. Tibetan headlamps and automatically change within the light, the light and the automatic such as a representative of the new structure and control method for improving the performance of the whole car played a great role. New research method of repair headlamps is very important, this paper illustrates the maintenance methods, steps, remove and principle.
