Arc-shaped surface light source lighting equipment for physical evidence photography

The utility model discloses arc-shaped surface light source lighting equipment for physical evidence photography. The device comprises a bearing support frame, a certificate storage plate, an arc-shaped illuminating lamp and a camera, the device further comprises an adjusting mechanism and an auxiliary mechanism. A certificate storage plate is mounted at the top of the bearing support frame; adjusting mechanisms are symmetrically arranged on the two sides of the top of the load-bearing supporting frame, each adjusting mechanism comprises adjusting supports symmetrically installed on the top ofthe load-bearing supporting frame through shaft rods and an adjusting gear located on one side of the adjusting support, and gear discs are fixedly connected to the positions, corresponding to the meshing positions of the adjusting gears, of the adjusting supports. An adjusting mechanism mounted on a load-bearing support frame is designed; the angle of the adjusting support is finely adjusted, the functionality of the arc-shaped area light source lighting equipment is greatly improved, the stability of the adjusting support in the standing process is greatly guaranteed through screwing and fixing of the stop nut and the shaft rod threaded base, and the situation that an irradiation point moves due to mistaken touch of external force is avoided. 本实用新型公开了一种物证摄影用弧形面光源照明设备，包括承重支撑架、存证板、弧形照明灯和摄影头，还包括调节机构和辅助机构，所述承重支撑架的顶部安装有存证板，所述承重支撑架的顶部两侧对称设置有调节机构，其中所述调节机构包括通过轴杆对称安装在承重支撑架顶部的调节支架，以及位于调节支架一侧的调节齿轮，所述调节支架上对应与所述调节齿轮的啮合位置处固定连接有齿轮盘；通过设计安装在承重支撑架上的调节机构，实现了对调节支架角度的微调处理，极大的增加了弧形面光源照明设备的功能性，且通过止动螺帽和轴杆螺纹座的旋合固定，极大的保证了调节支架在静置过程中的稳定性，避免了因外力误触而导致照射点发生移动的情况。
