Window optical dimming device

The present invention relates to a dimming device, and more particularly to a window optical dimming device having a bright and dark state change pattern.

Dimming devices commonly used in windows (such as curtains and blinds) are everyday items that are commonly used and widely used in home or office environments. The main purpose is to properly block light and provide visual shielding and increased privacy.

However, the commonly used window dimming device can produce a full-closed shading effect, which can prevent a large amount of light from entering the room to achieve the purpose of shading, but the general window dimming device can only be fully open or fully closed, and does not have a middle portion. Light-adjusting, partially shaded light adjustment function. In addition, window dimming devices (such as curtains, blinds) use fabrics, so there are disadvantages of easy dusting and difficult to clean. It is also worth noting that such window dimming devices need to preset a space to place the window. Optical devices (such as curtains and blinds) have the disadvantage of occupying a large volume.

The window optical dimming device of the invention has a combination of two sets of phase difference film and an optical sheet of a polarizing film, and two sets of optical sheets are respectively placed on the front and back sides of the window, so that the two sets of optical sheets are relatively displaced, and the optical sheet can be produced. Bright and dark patterns of change. Compared with the conventional curtain or blinds, the present invention provides optical dimming function with full bright state, partial bright state and full dark state due to the relationship between the two sets of optical sheets, and the thinness of two sets of optical sheets. Characteristic, therefore, the invention The window optical dimming device has the advantages of small size, adjustable light quantity, and variable pattern (anti-spy function).

The invention relates to an optical dimming device for a window, the optical dimming device comprises: a combination of two optical sheets, each optical sheet combination having a combination of a phase difference film and a polarizing film having the same arrangement pattern; two sets of fixed units, respectively The above fixed two optical sheet combinations; and at least one set of mobile units are coupled to one of the fixed units. Wherein, the phase difference film of each optical sheet combination has a plurality of regions, and the optical axis direction of each region is different from the absorption axis of the polarizing film by an angle of +45 degrees or -45 degrees, and the phase difference film is at the absorption axis of the polarizing film. The parallel and vertical extension directions, through at least one axis of the plurality of regions, must pass through the regions of the two optical axis directions.

The invention moves a set of fixed units by moving at least one moving unit on the optical dimming device, so that the two sets of optical sheets are combined to generate a relative displacement to generate a bright and dark state pattern change, so that the window optical dimming device is generated. The effect of adjusting the amount of light in all bright states, partial bright states, and all dark states.
