One kind of headlamp tester unaffected by the detection distance

摘要

During the safety testing of in-use vehicle and the factory inspection and adjustment of vehicles in manufacturing factory, the headlamp tester is needed to test the working status of vehicle headlamp. This paper firstly analyze and discuss several problems of headlamp tester during actual use process, in particular to the differences between vehicles parked position and the ideal position, which may lead to the the deviation of test results; secondly make the experimental study, for example, the headlamps tester MQD-6A, the data show that the design can overcome these problems and obtain better measurement result.
