Hollow light-adjusting glass

The utility model provides hollow light-adjusting glass, which belongs to the field of glass and comprises two transparent substrates arranged in parallel, structural adhesive is arranged on the peripheries of the two transparent substrates to form a hollow cavity, and spacing bars are arranged at two ends of the hollow cavity in the length direction. A hollow cavity is formed in the transparent substrate, at least one dimming unit is arranged in the hollow cavity and divides the hollow cavity into a plurality of hollow cavities, the dimming units and the transparent substrate are arranged in parallel, and the positions of the spacing bars do not exceed edge sealing areas of the dimming units; heat insulation films are arranged on the same sides of the two transparent substrates and the dimming unit. According to the dimming glass, the heat transfer coefficient of the dimming glass is effectively reduced, the heat insulation and heat preservation effects are enhanced, the risk of abnormal color change of the
