One of the common problems in today’s apartment houses is that many floors do not have access to natural sunlight. This issue not only increases the amount of electricity consumption, but also has a negative impact on people’s health. These buildings are called low light or no light. For this reason, experts in this field have always been looking for a way to transfer sunlight into dark buildings, especially for the northern or dark units of the building at all hours of the day. Smart skylight is one of the latest technologies that is used to transmit sunlight with a mirror to northern buildings or buildings with low light. Sunlight transmission tunnels or channels are also called this type of system. If you also want to make the sun a guest in your home during the day, stay with this article until the end.
passive (inactive) and active (active) light transmission systems
Various methods have been used to transmit sunlight inside the building. These methods include passive and active systems. Passive lighting systems include all architectural elements or equipment that direct sunlight into the building, passive lighting systems do not use electronic systems to track or transmit light. One of the examples of passive systems is the installation of a number of fixed mirrors on the skylight of the building to transmit light, in this method, for example, 3 mirrors are installed in three directions on the skylight of the building, but this system only works during certain hours and works throughout the day. It was not suitable.
In active lighting systems, sunlight is collected and directed into the building by combining electronic, mechanical and optical equipment with the help of a tracking system or solar tracker.
Smart solar skylights
Smart solar skylights are examples of daytime lighting systems with active systems. In this system, with the help of mechanical mechanisms, electronic programming and very accurate sensors, sunlight is intercepted and guided inside the building. These mirrors have an advanced electronic part that is responsible for calculating the right angle to receive light and transfer it to other floors. Novin Afog company has launched two models of active sun tracking systems named Roshana 110 and Roshana 220. . These systems track the sun based on the optical sensor or the geographic location of each area (GPS). In this way, in 6-10 hours of the day, they can intercept the natural light and transfer it to the lower floors of the building with the help of light reflection panels. These systems are usually installed on the roof and next to or on the skylight. With this method, you can solve the problem of dimly lit houses.
The advantages of using smart solar skylights in the building
Transmitting sunlight with rotating mirrors has the following advantages:
Transmission of natural light between 6-9 hours during the day to the dark floors of the building (northern buildings), underground, swimming pool, staircase, ground floors
Increasing the value (financial and spiritual) of the dark units of the building
Increasing the mental health of residents of dark buildings
Reduce electricity consumption
The ability to access the lower floors of the building to natural sunlight
Can be used in buildings with different uses and heights (up to about 20 floors)
No need for permanent maintenance due to the proper insulation of the system
The structure of the sunlight transmission system inside the building
This question has probably arisen for you as well, whether it is possible to use any type of mirror to transmit sunlight inside the building? In answer to this question, we must say that the means of transferring sunlight into the building are usually plastic, metal or glass sheets with a mirror coating on them. One of the important points in these tools is the intensity of light reflection and transmission, which is effective in the final performance of the system.
In what places are automatic sun reflection mirrors used?
One of the biggest advantages of installing a smart skylight in a building is that there is no limit to its use in different buildings. You can use this very practical tool to transfer sunlight into buildings such as schools, stores, factories, offices, airports, clubs and homes. The use of solar panels in such places will reduce energy consumption, increase people’s mental health, and as a result, increase their efficiency and concentration during work. Bright skylights, like solar tubes that transmit natural light or optical fibers, can also be installed in buildings with different shapes of skylights. For example, bubble, opening or acrylic skylights can be used in buildings.
In general, the main application of installing sunflower mirrors is to bring sunlight to the northern and dark units of the building, which are deprived of natural light during most hours of the day. In addition, it is possible to direct the light to other units of any building by installing fixed mirrors in the path of light transmission to the lower floors. Sunlight is transmitted inside the building units with a mirror.
Sunflower mirrors are one of the newest systems used to transmit natural light into the building. This smart and powerful lamp can follow the sunlight by relying on its electronics and mechanics and bring you light at all hours of the day. In this article, we tried to familiarize you with how it works and the advantages of using the sunlight transmission system with a mirror.
Frequently Asked Questions
There it possible to save sunlight with a smart shutter?
no The mechanism of sunflower mirrors is such that they can follow the sun and reflect the sunlight into the building during all the hours that the sun is in the sky. But these systems cannot store sunlight for use at night.
Is it possible to transmit sunlight inside the building on cloudy days?
In general, whenever it is possible to use natural light, smart lighting systems show good performance. But in cloudy weather, when the sunlight is not in the sky, the ambient light is reflected to the building. In general, in cities like Isfahan, more than 80% of the days, i.e. about 300 days, are sunny. (Imna news agency)
