Investigation of the light homogeneity on position functions in automotive rear light products

In the beginning of automotive history, automotive lighting products which provide vision at night driving, started to become products that provide to able to be seen and provide signalization with increasing security needs. Nowadays, these products also start to become constitute the identity of the vehicle and brand, increase the competitiveness with being eye-catching thanks to occurred opportunity along with increasing technology. For this reason, the expectation of the manufacturers especially from the quality of automotive backlight products is increasing. In order to maintain this quality to a certain standard in each product, each manufacturer publishes its own standards. The greatest expectations of the automotive manufacturers, especially from the exterior rear lighting products, in addition to meeting the legal regulations, are to meet the expectation of homogeneity that they have previously determined and standardized with mathematical evaluations. This expectation can be tested both in design and in the final products with the brightness camera. This thesis aims to provide an alternative using a very expensive device such as a luminance meter camera in the testing of final products. In this study, an easy, fast and low cost way to evaluate the light homogeneity of real parts by image processing method is explained. This thesis compares the luminance meter camera with the digital camera in particular and investigates the reliability of the digital camera for such an evaluation.
