In this case, the liquid crystal molecules are oriented in a completely regular way and the incoming light passes through these oriented channels and the glass becomes transparent.
In the off state, the liquid crystal molecules are randomly oriented and cause the glass to become opaque by scattering light. Using a dimmer, you can control the amount of light passing through and adjust the transparency of the glass.
Energy consumption has grown steadily in the last decade. Uncertainty in the availability of the usual fossil fuels, which the society’s energy consumption heavily relies on, has caused a significant increase in the cost of energy in the world. About 20% of Conventional fossil fuels are used for heating and cooling homes and office and commercial buildings. To reduce dependence on fossil fuels and reduce greenhouse gas emissions, it is necessary to think of solutions to reduce energy consumption in buildings.
The sun can be considered as a huge source of energy for the next 5 billion years. The sun is the beginning of life and the origin of all other energies. About 6000 million years have passed since the birth of this fiery ball, and every second 2.4 million tons of the sun’s mass is converted into energy. Sunlight is the source of existence and the boundary between light and darkness. Today, the importance of light and brightness in human daily life is fully accepted. Today, light is a very important design element for hotels, hospitals, stores, shops, and offices. And residential houses have been converted. Being light is one of the most important factors that challenges interior designers in the design of buildings under construction today. Studies show that people are happier and healthier when they live in a bright and well-lit environment. are more efficient. The vital role of light in human health has been fully proven today. For this reason, in the construction of new buildings, it is necessary to take more time to design this building for the availability of more light through glass windows. spent
Today, about 30% of the energy of a building in Iran is wasted through glass windows, which is about 5 times that of European buildings. Glass, as one of the most diverse and influential building materials, creates great opportunities to create extraordinary creations in architecture and interior design. In fact, glass helps a lot in diversifying our work and living spaces. Many efforts It has been done to reduce energy consumption through glass windows. Various solutions such as better insulation, using sealants, using double-glazed windows and using thick curtains in front of the windows have been used to reduce energy wastage in the building. is that one of the newest and most efficient ways that has found many uses today is the use of smart glasses.

The discovery of what is known today as liquid crystal began in the late 19th century by an Austrian scientist named Friedrich Reinitzer. He discovered the liquid crystalline nature of cholesterol extracted from carrots. This work has been studied and researched by scientists and different companies for about a century. In the late 20th century, the liquid crystal display (LCD) was invented and is now used worldwide in monitors and smartphones. This technology has been used not only in electronics but also in glass applications.
Liquid crystal smart glass technology is one of the types of smart glass manufacturing methods. In this type of technology, by using electricity, the glass has the ability to pass and prevent sunlight from entering the building and removes up to 98% of ultraviolet and infrared rays. By blocking ultraviolet rays, many objects Especially objects near the window are protected from damage. Considering that these rays are important sources of heating, the use of smart glasses as an obstacle to the transmission of infrared rays into the building reduces the consumption of cooling devices in the hot seasons of the year. It should be noted that the amount of electricity consumed by this type of glass is very small.
To make this type of glass, liquid crystals surrounded by polymer layers are laminated between two layers of electron conductors, two polymer layers, two inner protective layers and two glass plates. becoming is used. In the presence of electric current, the existing liquid crystals are oriented in the same direction, and for this reason, they allow any light to pass through them, and the glass can be seen completely transparently. As soon as the electric current is cut off, the order of these liquid crystals is lost and the liquid crystals are completely randomly oriented between the polymer layer. For this reason, this layer does not allow any kind of light to pass through it, and the glass turns from transparent to opaque. The objects behind the glass can no longer be seen. The conversion of a smart glass from a transparent state is done in a very short time, about 200 milliseconds.
Liquid crystal smart glasses work with a relatively low voltage. Using a transformer, the city 220 V is converted to 60 V. Therefore, the cost of electricity consumption of this type of smart glass is very low. Also, for more convenience and to choose the right solution for emergency situations, both the mechanical switch and the remote control are used to install smart windows.
