Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamp detection, and particularly relates to a vehicle lamp dimming test device. Background Art

[0002] In the prior art, when developing a new dimming standard part for an automotive lamp or making a test plan to check whether the performance of an existing dimming standard part meets the requirements of the whole lamp, generally only the performance of a single part is verified, or verification is carried out by means of a specific project. As a result, the following problems exist: on the one hand, if only the performance of a single part is verified, the performance that the single part needs to meet on the whole lamp may not be fully converted into the performance of the single part, resulting in incomplete verification; on the other hand, if a specific project is borrowed, due to the limitations of the overall size, dimming point spacing, dimming load, etc. of the borrowed project, the test cycle will be long, the dimming spacing and load will be single, and the cost will be high. More specifically, firstly, when using a specific project to conduct shock and vibration tests, due to the limitations of the test bench size, generally only one set of lamps can be verified in one test at most; secondly, using a specific project to conduct verification tests requires the use of a complete set of related parts, and these parts are basically scrapped after the test, consuming a relatively large amount of part resources; thirdly, the dimming spacing and dimming load of a certain project are unique, that is, both the vertical wheelbase and the horizontal wheelbase are fixed values, and the dimming unit is also a fixed value, and it is impossible to judge whether it is feasible when applied to other wheelbases and loads, or to collect the situations of other projects for test planning, which will be restricted by the actual situation of the project; fourthly, for dimming standard parts, different materials of the parts inside the headlamp need to be considered. If re-commissioned for production, it involves the production of the entire housing and the entire bracket, consuming a large amount of test plate resources. Summary of the Invention
