One-way perspective window system

Abstract

The invention provides a one-way perspective window system which comprises a light valve device, a first lighting device and a control module. Due to the fact that the control module is connected to the light valve device and a first adjustment module of the first lighting device, and the switching frequency and timing sequence of the first lighting device and the light valve device are synchronously controlled, the one-way perspective window system is capable of providing the good peep-proof property, and the system is not affected by the light of the external environment of the system.

Description

technical field [0001] The invention relates to a one-way see-through window system. Background technique [0002] Known one-way see-through devices with a similar one-way see-through effect generally include an opaque film structure with a plurality of holes, or a semi-transparent metal film structure. In fact, the principle of forming the one-way see-through effect is by The above-mentioned structure makes the light transmittance and reflectance of the two sides of the device inconsistent with the light, so that the reflectance of the device is higher than the light transmittance side, and it is difficult to see the other side of the device whose reflectance is lower than the light transmittance. However, as the ratio of the light intensity of the environment on both sides of the device changes, the one-way perspective effect may still be weakened or disappeared. For example, the window of a building using a conventional one-way perspective device, when the outdoor light i...

[0002] Known one-way see-through devices with a similar one-way see-through effect generally include an opaque film structure with a plurality of holes, or a semi-transparent metal film structure. In fact, the principle of forming the one-way see-through effect is by The above-mentioned structure makes the light transmittance and reflectance of the two sides of the device inconsistent with the light, so that the reflectance of the device is higher than the light transmittance side, and it is difficult to see the other side of the device whose reflectance is lower than the light transmittance. However, as the ratio of the light intensity of the environment on both sides of the device changes, the one-way perspective effect may still be weakened or disappeared. For example, the window of a building using a conventional one-way perspective device, when the outdoor light is generally much lower than the indoor light at night At this time, even if there is a conventional one-way see-through device with a reflectivity higher than the light transmittance on the outside of the window, because there is no interference of light reflection outdoors, brighter indoor scenes can still be seen, which affects the privacy of people indoors; therefore However, the conventional one-way see-through device cannot avoid such situations, and only curtains and other coverings can be used to block it, but it also makes the two sides of the conventional one-way see-through device, such as the indoor and outdoor scenes of the building, invisible

[0003] In addition, in another application of the known one-way perspective device, such as the animal exhibition hall of the current zoo, it is usually separated by a transparent glass curtain to form two closed spaces on the side of the animal and the side of the audience, and the side of the glass curtain is also usually closed. By adopting a conventional one-way perspective device, when the light intensity on the animal side is greater than that on the audience side, the animal will not be affected by the actions and scenes of the audience side, so that the audience can enjoy the animal and prevent the animal from being disturbed by seeing the crowd. However, the light intensity on the audience side should be lower than that on the animal side as much as possible, which may cause safety problems and inconvenience due to insufficient light; especially for exhibition halls of nocturnal animals, the animal side has only weak lights, and the light on the audience side is even darker. It needs to be in a state of almost no external light source, so it has an impact on the convenience and safety of the audience
