Abstract

The invention discloses an automobile dipped headlight illuminance distribution test bench based on bench test and a test method thereof, and belongs to the technical field of automobile headlamp optical performance test, and adopts an automobile lamp light distribution test system to respectively carry out bench test of pavement illuminance distribution on left and right dipped headlights. A dipped headlight illumination distribution result, namely an illumination value of each measurement point, in the whole vehicle state is obtained according to the proposed calculation method, and the measurement result is evaluated. The invention has obvious advantages in the aspects of improving the dipped headlight illuminance distribution test efficiency, shortening the test period, saving the labor cost, ensuring the test result consistency, avoiding the external environment interference and the like, and can solve the defects of the traditional pavement illuminance distribution test based ona real vehicle; and the development requirement of the passenger vehicle dipped headlight illumination distribution test is met.

Description

technical field [0001] The invention belongs to the technical field of optical performance test of automobile headlights, and in particular relates to a bench test-based test bench for illumination distribution of low beam headlights of automobiles and a test method thereof. Background technique [0002] The dipped beam of a car is a lamp that illuminates the road ahead of the vehicle without dazzling or causing discomfort to oncoming drivers and other road users. The dipped beam is a must-have headlight for the car, which affects the safe driving of the car. The distribution of road illumination intensity of low beam headlights is an important optical performance requirement of automobile lighting fixtures. Under the conditions of simulating real vehicle installation and standard test voltage, test whether the illuminance of each measurement point of low beam headlights meets the relevant design or standard requirements. Currently, real vehicles are used to test low-beam r...
