Light transmission detection device for multistability liquid crystal privacy glass

Abstract

The invention relate to a light transmission detection device for a multistability liquid crystal privacy glass. The device comprises a bottom plate, wherein a light source emitting device, a fixing device and a reflector are sequentially arranged on the bottom plate from front to back; the light source emitting device comprises an emitting frame which is arranged on the bottom plate in a slidingand matching manner; an illuminating lamp is fixedly arranged at the upper end of the emitting frame; and a positioning mechanism is arranged in the emitting frame. The device can solve the problems that the glass needs to be fixed manually in the light transmittance detection process of the existing privacy glass, the stability of manual fixing is poor, so that the glass is easy to slide and break, the hidden danger of scratching workers exists, and the safety is poor; the device needs to manually control the light source to irradiate the glass, the distance between the light source and the glass cannot be accurately controlled, and the collected glass transmission data has errors, so that the data affects the accuracy of the glass transmission detection and the like.

Description

technical field [0001] The invention relates to the technical field of dimming glass, in particular to a light transmittance detection device for multi-stable liquid crystal dimming glass. Background technique [0002] Dimming glass is a new type of special photoelectric glass product with a laminated structure that combines liquid crystal film into the middle of two layers of glass and is glued under high temperature and high pressure. The parameter of light transmittance of dimming glass is one of the main factors for evaluating dimming glass. one. [0003] At present, the light transmittance detection of dimming glass has the following problems: [0004] a. The glass needs to be fixed manually. The stability of manual fixing is poor, and it is easy to cause the glass to slip and break, and there is a hidden danger of scratching the staff, and the safety is poor; [0005] b. It is necessary to manually control the light source to irradiate the glass, and the distance bet...
