Abstract
The present invention belongs to the technology field of a tool for testing an optical property of a structural member, and discloses a polarizer support member of a lighting-inspection equipment and a lighting-inspection equipment. By providing a connecting portion at each corner region of the support plate, and providing a fixing member which is detachably connected with the connecting portion at a location on the frame of the lighting-inspection equipment corresponding to each connecting portion, the forces applied to the support plate between the connecting portions and the fixing members are balanced so as to remain the support plate in a horizontal state, thus, the supporting stability of the support plate is ensured and the damage to the panel or other parts due to the sag of one end of the support plate is avoided. In addition, the structure of the support member is simple and the installation and detachment of the support is easy. The lighting-inspection equipment having the above polarizer support member as its upper polarizer support member can stably support the upper polarizer support member, and have a better inspection effect.
