Testing device for vehicle lamp module and testing method thereof

Abstract

The invention belongs to the technical field of night optical testing of car lamp light-emitting modules, and relates to a testing device for a vehicle lamp module, the testing device comprises a testing rack and a module adjusting tool, the testing rack is provided with a supporting plate capable of moving up and down, and the module adjusting tool is installed on the supporting plate in a left-right moving mode. The module adjusting tool is provided with a vehicle lamp module and a test light source assembly matched with the vehicle lamp module, and the vehicle lamp module can be subjected to vertical angle adjustment on the module adjusting tool. The height, width and angle of the vehicle lamp light-emitting module can be adjusted, the night testing efficiency and accuracy of the vehicle lamp light-emitting module are greatly improved, and the device has the advantages of being simple in structure, convenient to operate, ingenious in design, low in cost, small in size, detachable, high in practicability, convenient to popularize and the like. A good implementation method is provided for night optical testing of the vehicle lamp light-emitting module, and the device has great market value and is worthy of further popularization and application.

Description

technical field [0001] The invention belongs to the technical field of night-time optical testing of vehicle light emitting modules, and in particular relates to a testing device and a testing method for a vehicle light module. Background technique [0002] Due to the popularization of the modularization of lamps in the front of the car, major OEMs will choose to test the light-emitting modules designed by the lamp factory individually. However, because the module itself does not have the function of dimming, and the current device used for nighttime optical testing basically cannot set the distance between the light patterns, the relative height of the light pattern, and the light pattern of the two tested modules (left and right lights). Moreover, different body heights (there are differences in the heights of sedans, SUVs, and different customer models) cannot be well adjusted. As a result, the accuracy of the nighttime optical test of the car light module was questioned...

Problems solved by technology

However, because the module itself does not have the function of dimming, and the current device used for nighttime optical testing basically cannot set the distance between the light patterns, the relative height of the light pattern, and the light pattern of the two modules (left and right lights) to be tested.

Moreover, it cannot be well adjusted for different body heights (there are differences in the heights of sedans, SUVs, and different customer models)

As a result of the above, the accuracy of the nighttime optical test of the car light module has been questioned by customers, and even affected the effect of the superimposed light pattern of the light module, resulting in unsatisfactory test results.
