Description

Technical Field

[0001] The invention relates to the technical field of automobile lamp light distribution testing, and in particular to a universal license plate lamp light distribution testing tool. Background Art

[0002] As a criterion for judging whether a lamp meets national requirements and can be installed on a vehicle, the lighting regulation test for automobile lamps has a priority position in the field of automotive light optical design. Whether the lamp design itself meets the requirements and whether the test method meets the specifications have become the two key factors in judging whether a lamp can pass the certification.

[0003] The accuracy of the test is inseparable from the light distribution tooling that meets the precision requirements. According to the type of lamps, the test unit of most signal lights is luminous intensity. The regulations of different countries have different test angle ranges and values ​​for light intensity. Therefore, in general, the same set of light distribution tooling can be used for testing of all national regulations, and there is no need to design tooling separately for different countries and different lamp placements.

[0004] Unlike most signal lights, license plate lights test the brightness of the plate reflected by the light hitting the plate, which is related to the relative position between the plate and the light. Different relative positions require a separate set of tooling. In addition, the sizes of license plates and test points in different countries are also different. For example, the sizes of national and new energy license plates are 440*140 and 480*140 respectively, the common size of European license plates is 520*120, the American license plate is 300*150, the Egyptian license plate is 350*170, the Australian license plate is 372*136, the Ecuadorian license plate is 404*154, and the Russian license plate light is 520*112, involving 109 different sizes of countries. In addition, the national and European standards require 12 test points on the license plate, and the American standard requires 8 test points. In this case, ordinary tooling will cause a lot of time and resource waste due to the non-adjustability of the position of the license plate light and the license plate, and the non-replaceability of the license plate light and the license plate. For a license plate light of a certain design, a separate set of tooling is required for each country's regulatory certification test. The processing time of a lighting fixture often takes more than one month, which puts great pressure on the project development cycle and cost. Summary of the invention
