Reading lights are installed inside the car, on the top of the driver's seat and the top of the middle of the back seat, for easy reading in the car. Ambient lights are a kind of decorative lighting, usually in red, blue, green and other colors.

[0003] A Chinese patent with announcement number CN206321407U discloses an automobile interior light testing device, including a cabinet, a display, an interior light positioning tool, a start button, a lens and a camera. The display is hung on the upper front of the cabinet, the interior light positioning tool is arranged in the middle of the cabinet, and the lens is arranged inside the rear baffle of the cabinet and suspended directly above the interior light positioning tool.

[0004] Due to the different car models, the installation positions of interior lamps are also the same. At the same time, due to different car manufacturers, the target areas and angles of lamp testing are also different. The above technology positions the interior lamps in the middle of the cabinet during testing, which makes it only applicable to interior lamp testing in this case, and cannot be applied to the testing of lamps in different car models. There are certain limitations. Utility Model Content

[0009] By adopting the above technical solution, the tester installs the tested lamp on the fixed bracket, and then adjusts the position of the longitudinal axis, transverse axis and the fixed bracket through the driving component to adjust the illumination range of the lamp on the fixed bracket, and relies on the optical detection mechanism to adjust the illumination angle of the lamp, so as to adapt to the testing needs of different lamps installed on the fixed bracket, so that the tested lamp reaches its actual installation position in the vehicle, which is conducive to improving the adaptability of interior lamp testing for different models.
