Description

A glass with a choice of viewing angles

technical field

The utility model belongs to the field of glass manufacturing, and in particular relates to a glass with the combination of two-way visibility and anti-peeping function for controlling the angle range and selecting the viewing angle.

Background technique

Transparent glass can block a space while allowing light to penetrate, but light transmission is often a problem if privacy and sun protection are desired.

Today, with continuous technological innovation, the glass used in buildings on the market is mainly made of more than one piece of transparent glass or coated glass. It cuts off the visibility of both sides, so it lacks flexibility and cannot be properly illuminated.

If frosted glass is used, although it can introduce soft light from the outside, it still cuts off the visibility of both sides.

If a layer of highly reflective film is pasted on the glass surface, although the indoor scene cannot be seen when the outdoor light is strong during the day, the indoor scene can still be clearly seen outside at night when the indoor lighting is turned on.

If the liquid crystal glass with electro-controlled transmission is used, the market price is about 4000-5000 yuan per square meter, and its expensive price is not as good as directly installing a plasma TV in terms of application value.

Although the venetian blinds can be used to select the range of viewing angles, they not only take up space after installation, but also tend to accumulate dust, and require repeated and difficult-to-clean work for a long time. Although the hollow venetian blind glass eliminates the cleaning problem, power supply and mechanical failure determine the service life of the hollow venetian blind glass, and the hollow venetian blind glass is limited to vertical installation, and cannot be used as a horizontal installation such as a lighting roof.

Utility model content

The technical problem to be solved by the utility model is to provide a glass with a selectable viewing angle, which has a simple structure, meets lighting requirements, has high penetration resistance, prevents peeping, and is easy to implement.

The following is an example of the application of the above glass:

Example 1: The glass selected for the viewing angle is transparent glass within the viewing angle range, but it has a frosting effect outside the viewing angle range. For example, when walking through a glass window in a shopping street, what you see at first is a foggy effect. As the angle of the observer walks changes, the glass window gradually changes from translucent to transparent. During this process, you can see the displayed The products are placed in the transparent glass surface window, so it is often considered an illusion. Of course, it can also be made into a piece of glass according to the needs. Two angles can form obvious transmission.

Example 2: Select the glass with viewing angle to be used in the installation of sightseeing elevator, bathroom or dressing room glass, which can be used for normal lighting, but the relative angle cannot peep into the indoor scene. If it is used on a display or projection screen, it can prevent peeping from other angles .

Example 3: The advantage of choosing glass with a viewing angle in the lighting roof is that the purpose of the lighting roof is to allow more lighting in the room, but excessive light incident into the room leads to a strong light environment, such as the light incident on the ordinary glass lighting roof The light can enter the room between 7:00 and 18:00, but the sunlight at noon is too strong. If the glass with a viewing angle of ±25°～±55° is installed on the lighting roof, it can eliminate the excessive sunlight at noon. light incident.
