The sun is the greatest thing that human eyes can see.
Davydov Robert Borisovich

Light guides-- this is very interesting solution. Solutions for insolation appeared on Russian market relatively recent and not yet widely used. At the moment, they are mainly used by large advanced companies.

The main advantage of light guides is sunlight, and that says it all. Man organically requires natural light, and no artificial sources of illumination can replace it.

What rooms are illuminated with light guides?

In additional solar lighting, basements, basements and rooms on the shady side of the building are needed.

How does a light guide work?

The light guides use Raybender technology, patented by Solatube.

The principle of operation is simple: the light is captured by the light-collecting dome and transmitted through the channel to the room.

The light-collecting dome (marked 1 in the figure) is installed on the roof or facade of the building. Light is captured even at dusk or in cloudy weather. the use of a special lens (2) allows you to increase the capture area.

The light guide channel (3) is a tubular light guide. It is able to transmit light at a distance of up to 12 meters with virtually no loss. in this case, the channel configuration can be quite bizarre.

At the end of the channel there is a diffuser (4). It is installed on the ceiling and looks like a lamp.

One such light guide can illuminate an area of ​​14 -40 m 2 .

Why a light guide and not a window?

energy efficiency

The main heat exchange in the house occurs through the windows. In winter, the heat escapes through the windows, in the summer the heat penetrates. In any case, the cost of either heating or air conditioning increases. When using light guides, there is practically no heat loss. As a result, you seriously save on maintaining a comfortable climate in your home.

Possibility of installation

Not everywhere you can install a window. In the basement, the window does not make sense, but the light guide does :)

Uniform illumination of large rooms

Possible difficulties

Daylight hours

The first and obvious objection to the use of light guides is the short daylight hours in our lane, especially in winter and autumn, when the sky is covered with clouds.

For owners of their own homes, a new fixture, light-guiding pipes, has recently appeared, which can be used as a replacement for skylights, which is cheaper and requires less labor.

If you're thinking about adding some sunlight to your kitchen or dark hallway, then a solar chimney might be the way to go. It will cost only a fraction of the cost of installing a skylight and will bring pleasant daylight to the right room.

How it works

Known by various names: solar tube, light pipe, light tunnel is metal pipe diameter is usually from 25 cm to 35 cm with a polished inner surface. The inner surface acts as a continuous mirror, transmitting light along its entire length and maintaining its intensity. Reception of light rays occurs on the roof and then they are sent to the inside of the house.

A plastic sphere is installed on the roof above the pipe to protect it from the weather. The pipe ends with a diffuser on the ceiling of the room where it is led. The sphere collects light from the outside, the diffuser distributes it with an even white glow. The result is amazing, with a recent installation, owners often reach for the light switch when leaving the room.

Price

Such systems are just appearing in our country and their cost is still quite large, but the cost reduction is a matter of time. In Australia and the USA, such systems have already established themselves in the market and competition has begun, leading to a decrease in cost. In the USA, the cost with installation is an average of $500, it is worth noting here that they have an installation cost roof window the average is $2000. As a result, light guide tubes are becoming more and more popular. For those who climb onto the roof for installation themselves, the system kit costs only $150 to $250. And here everything is easier compared to skylights, no new drywall inserts, painting, changes in frame elements are needed.

How much light?

Light from a pipe with a diameter of 25 cm, the most small version, approximately equal to the lighting from three 100-watt lamps, which will be enough to illuminate a room of 20 square meters. m. With a diameter of 35 cm, there will be enough light for an area of ​​\u200b\u200babout 28 square meters. m.

Able to turn a gloomy dark attic into a well-lit room. The use of skylights is perfect solution in order to reduce the cost of electric lighting in the attic. However, there are rooms in the house where it is impossible to install any windows. In this case, the problem is solved by tubular light guides.

Tubular light guide system was invented in Australia in 1991. It consists of three parts: a transparent dome-concentrator of sunlight, a light guide, a diffuser. Sunlight passes through a transparent dome made of shock-resistant polycarbonate, installed on the roof of the building, and is directed into the room through a pipe, which is a light guide. With the help of a diffuser mounted on the ceiling, the room is illuminated with a surprisingly soft diffused light. natural light. Daylighting has been proven to have a positive impact on human health and increase productivity.

The dome is a concentrator of light and allows you to collect light even in the case of a low position of the sun in the morning or evening hours. Light guides, the length of which is from 1.5 to 3 m, are installed between the truss structures and ceiling beams. Two types of light guides have been developed: a flexible light guide and a rigid tube with a reflectivity of up to 98%. Through a diffuse diffuser, natural light is directed to problem areas: the hallway, bathroom, kitchen, cabinets. System Solatube blocks up to 99% of ultraviolet radiation, which adversely affects human health.

The manufacturer recommends using flexible light guides up to 3 m long, and rigid light guides up to 6 m. However, you should be aware that as the length of the pipe increases, the light transmittance decreases, regardless of the materials used.

Diffuser 25 cm in diameter, installed in a room of 14 sq. m., gives illumination equivalent to three 100 - watt incandescent lamps, model with a diameter of 36 cm can provide with adequate lighting, a room twice as large. The diffuser looks like a regular ceiling light.

Models with a remote control allow you to change the lighting, for example, in rooms such as a bedroom. There are systems equipped with additional electric lamp which turns on at night.

Some models are equipped with a fan installed in the branch of the light guide.

System efficiency Solatube depends on the time of year, time of day, diameter and length of the light guide, on the orientation of the dome-concentrator on the roof.

The system is easily mounted in just 2 hours on any roof. The cost of installing one guide is about 15 thousand rubles.

After a place has been found for a new roofing element and a cutout has been made in the roof, a nail is hammered into the sheathing of the slopes (here it is a profiled board), which will protrude from the side of the room, marking the center of the future hole.

Rainwater drainage
To drain rainwater, a rail with a slight lateral slope is built in over the structure of the light tunnel so that it is cut across in this place and glued onto the rail.

Two in one: combined lighting

In the space equipped with a light tunnel, artificial lighting will also have to be used at night. To do this, the light tunnel and electric lamp can be combined into one design using a special lighting kit with a tripod and an E-27 socket, suitable for both conventional and energy-saving lamps.

1. A tripod on four supports is carefully mounted to the ceiling element.
2. The electric cable is pulled through holes pre-drilled in the wall of the pipe.

The efficiency of the light guide is at least 82%. At the same time, such positive traits natural lighting, as a continuous spectrum of light, the natural rhythm of illumination corresponding to the "bioclock" of a person, the natural dynamics of natural light, which makes it possible to judge the weather outside, i.e. provide maximum communication with the external environment.

SW530 SERIES LIGHT GUIDE PROVIDES LIGHTING AT LEAST 30 m2

The light guide SW530 is designed to illuminate large rooms - classrooms, classrooms, laboratories, conference rooms, classrooms, offices. The solar tunnel replaces 6 armstrong lamps in summer and 2 armstrong lamps in winter. Gives out at least 5000 lm in cloudy weather and about 11000 lm in sunny weather. The heat of the sun will not pass through the light guide, which means there will be no heating of the room. And also the light guide will prevent heat loss and preserve the thermal integrity of the building.

APPLICATION OF SOLAR WELLS ALLOWS TO PROVIDE:

Efficient, healthy lighting on the upper floors of buildings and in deaf spaces;

Safe lighting of fire and explosion hazardous premises;

Safe lighting in rooms with high humidity, where there is a risk of electric shock;

The light tunnel has 13 positive factors in contrast to artificial lighting.

Artificial lighting - created by electric light sources. Natural lighting - created by direct sunlight and diffused light of the sky, varies depending on the geographical latitude, time of year and day, degree of cloudiness and transparency of the atmosphere. Sources of artificial light (AIS) are able to illuminate the target room around the clock, with one condition - in the presence of electricity. Those. in the absence of electricity in the network, there will be no lighting, which means that it will not be possible to use the room for its intended purpose. Light guide - not dependent on electricity during the daytime, i.e. You can use the room for its intended purpose as long as it is light outside.

Unlike windows, sources of artificial light do not lose the heat of the building; I, like light guides, perform their direct duty - lighting. The light guide is a hollow annular mirror (mirror tube), which is completely sealed, it excludes the possibility of convection air masses due to the built-in Thermal Barrier.

Possibility of installing lighting in any room It often happens that it is not possible to conduct light into a room that is located inside the house and does not have access to the outer walls. artificial lighting sources cope with this problem just like light guides, which are capable of conducting natural light at a distance of up to 20 meters deep into the building The light guide can easily illuminate any room remote from the roof or outer wall.

Illumination uniformity. With modern lighting sources ( LED lamps) very low uniformity close to unity. The light guide has a high uniform illumination closer to three.

Pulsation. Any artificial light source has a stroboscopic effect - in other words, there is a pulsation. Many have already experienced the non-visual impact of pulsing artificial lighting, which manifested itself in the form of a feeling of discomfort, fatigue, and even malaise that occurs under conditions that at first glance are good, brightly lit rooms or when working at a computer. The light guide is essentially a window or a spotlight, and like a periscope, it transmits sunlight without distortion and pulsations.

Glitter. Glare has a negative effect on eye function. Eyes do not have protection against glare. In the presence of high brightness, the functions of vision decrease, and a kind of temporary blindness occurs, which is called glare. A high degree of glare can cause visual impairment, headache. Glitter in production conditions is completely unacceptable. The presence of gloss in the workplace can lead to work injury. The diffuser of the light guide does not have a blinding effect, the light is evenly distributed over the entire area of ​​the room.

Heat inflows. Heat dissipation from the IMS is not so great, however, in accordance with normative documents they must be taken into account. The total heat input from IMS is no more than 3%. The light guide transmits heat less than 0.5%, raising the temperature in the room by no more than 0.003 ° C

Electrical and fire safety The light guide is electrically and fireproof. The light guide does not require electricity to perform its main function - lighting.

No energy costs for lighting The main advantage of the light guide is its direct economy. IIS do not have direct savings and can only be content with indirect ones.

O S
It is recommended to wipe the surface of the dome with a damp cloth 2 times a year.
It is forbidden to exert physical influence on the product.

For installation of light guides it is necessary:

Prepare holes in the roof and ceilings. (In accordance with SNiP 2.01.07-85 "Loads and impacts").

Prepare a box for a light shaft on the roof. The height of the shaft depends on the thickness of the snow cover in winter time(SNiP 23-01-99 "Construction climatology"; SNiP 41-01-2003 "Heating, ventilation and air conditioning").

Assembly of light guides:

First, the tubes are assembled according to the installation instructions.

Pipes are placed in the opening and fixed in floors(if the light guide passes more than one floor)

With a long length of the light guide, the pipes are assembled in segments and attached already in place. With a small length of the light guide (2-3 tubes), you can assemble the entire pipe and mount it as an assembly.

Familiarize yourself with the technical data sheet of the product

ADDITIONAL OPTIONS and ACCESSORIES

Installing such a device as a dimer (dimmer) will allow you to change the intensity of the general light in the premises.

The light corona is designed for additional lighting of premises with the help of light guides at night.

Heliostat technology "Peresvet" (developed by Solarzhi) is a fixed panel. Sunlight at low angles during sunrise and sunset, falling on the heliostat, is redirected to the mirror tube. The efficiency of the device is not less than 90% at angles from 0 to 15 degrees.
