Light guides. "Sunny Well" is a simple device that will deliver natural light into the darkest rooms solar pipes for lighting with their own hands

Can turn a dark dark attic into a well-lit room. The use of mansard windows is a great solution in order to reduce the costs of electrical coverage of 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 svetovoda.

System of tubular light guides It was invented in Australia in 1991. It consists of three parts: a transparent dome-hub, a light guide, diffuser. Sunlight passes through a transparent dome of impact-resistant polycarbonate installed on the roof of the building, and is sent to the room along a pipe that is a light guide. With the help of a diffuser installed on the ceiling, the room is highlighted by a surprisingly soft scattered natural light. It has been proven that daylight lighting has a positive impact on human health and increases productivity.

The dome is a light concentrator and allows you to collect light even in the case of low sun location in the morning or evening. Light guides, the length of which is from 1.5 to 3 m, are installed in the intervals of rafting structures and ceiling beams. Two types of light guides are developed: a flexible light guide and a rigid tube with a reflective ability to 98%. Through the diffuse diffuser, the natural light is sent to the problem areas: hallway, bathroom, kitchen, cabinets. System Solatube holds 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 fibers - up to 6 m. However, it is necessary to know that with increasing pipe length, the light transmission coefficient is reduced, regardless of the materials used.

The diffuser with a diameter of 25 cm, installed indoors of 14 sq.m., gives lighting, equivalent to three 100 - watt incandescent lamps, a model with a diameter of 36 cm can provide sufficient lighting the room is twice as the size. The diffuser looks like a conventional ceiling lamp.

Models with remote control allow you to change the illumination, for example, in such plasters as a bedroom. There are systems equipped with an additional electric lamp, which is included in the dark.

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

System efficiency Solatube depends on the time of year, time of day, diameter and fiber length, from the orientation of the arrangement of the roof dome.

The system is easily mounted literally in 2 hours on any roof. The cost of installation of one coherent about 15 thousand rubles.

Light lights -building elements of a building that is designed to illuminate the rooms by sunlight and reduce dependence on artificial lighting.

Especially light lights are used in those rooms where natural lighting through the windows is minimal (or absent), and there is the possibility of laying through a non-residential attic of the light tunnel. With the help of a light tunnel type lantern, you can provide natural lighting of rooms and rooms inside the house that do not have windows (for example, bath, toilet, dressing room, storage room, corridor, photo 1.).

Light lamp: where they use, the principle of operation, from which it consists of marking

Light lights are called different ways - "Light guides", "light wells", "light tunnels", SDS system (Solatube Daylighting System).

Filmers have recently gained popularity, as they have not a complex design and sufficiently high efficiency. Thus, Velux light tunnel (LoveGrove) in cloudy weather passes through itself up to 440 lumens (430 lumens - 40W incandescent lamp), and in sunny weather - 2800 lumens, photo 2.. One light tunnel light lamp can illuminate the room with an area of \u200b\u200b9 m 2.

Nowadays, the fibers are submitted by such manufacturers: Allux, Velux, Fakro, Soolarspot, etc.

Light guides can be installed both in a vertical, tilt position (roofing with an angle from 15 ° to 60 °) and in a horizontal position (wall).

Photo 3. Options for installing light tunnel

Tunnel light lights of different manufacturers may differ in some design elements, but in general consist of:

• external element - Located on the roof surface (usually inclined) and collects the rays of daylight. The outer element is a hemispher or spherical dome that collects the rays of light with the installed frinnel lenses. The dimensions of the upper element of the round shape with a diameter of 0.25 m, 0.35 m and 0.53 m (there are other sizes), the entire external part usually has a size of 0.47 × 0.47 m and more. The above-mentioned round outer elements are able to illuminate the area of \u200b\u200bthe room at 14, 24 and 40 m 2, respectively (with an height of 2.4 m);
• internal element - dispels and evenly distributes sunlight indoors.

External and internal elements are connected tunnel trumpetswhich are rigid or elastic (usually diameter 0.35 m, up to 2 m long, with additional connecting elements, you can leng up to 6 m).

The principle of operation of the light tunnel

The principle of operation of the light light tunnel type is very simple: the outer element collects the sun's rays and according to the reflective inner surfaces of the tunnel pipe transmits them to the inner element, which dispels the rays of light in the room. The inner surface of the pipes is covered with a layer of aluminum and additionally consists of 400 layers of a special reflective film (reflective ability - 99.7%). Such a surface is capable of collecting a huge amount of rays not only in cloudy weather, but even at night, from radiation of the Moon and urban lighting.

When laying a flashlight, it should be remembered that the longer the tunnel tube and the more bends, the greater the light reader:

• on each bend, losses are 10 ... 40%;
• at each meter, the loss pipe is 20 ... 40%.

To obtain the maximum effect of lighting using a tunnel flashlight, you must install the tunnel tube of the following length:

• hard tube within 0.9 ... 6.0 m;
• corrugated pipe 0.4 ... 2.0 m (corrugated pipe it is impossible to lengthen).

What are light lights?

A more detailed structure of the light guides, consider the example of the ALLUX and VELUX light guide system. The Lightwater Systems Allux consists of ( photo 4 and 5):

• dome (light radiation receiver);
• roofing block;
• a mirror tube or a fiber (a lightweight channel that transmits light rays due to their reflection from the surface of the pipe;
• diffuser (light solving).
• additional components (photo 6).

Dome Made of polycarbonate or tempered glass, which has unchanged light-conducting properties and high impact strength, photo 4b.

Dome Features:

• a special form and material of the dome allows not to carry out additional surface cleaning. It rain enough to clean the surface.
• the maximum collection of sun rays is happening in the morning and in the evening, as well as in cloudy weather.
• the dome is protected from UV rays.

Roofing block - this is an aluminum fiber part, designed to connect the dome to the roof and ensure reliable waterproofing, photo 5A..

Diffuser, also called the luminous diffuser - intended for uniform distribution and soft scattering of sunlight throughout the room. Diffuser made of double polycarbonate, photo 5b..

LightwaterAllux.(mirror trumpet) is intended to redirect the falling rays on the dome to the diffuser, and then to the room, photo 5, in, g. Such a scattering capacity of the fiber is provided by the mirror inner surface. The Allux manufacturer is produced in two versions:

• allux Plus light guide (aluminum material, hard, inside silver spraying), photo 5V.;
• allux Flexi light guide (in the form of corrugations, soft), photo 5g.

Advantages of applying different types of fiber:

Light tunnel marking

The Velux light tunnel has several varieties that are marked up photo 7.:

• TwF. - light tunnel with a corrugated pipe, also has a built-in waterproofing salary for mounting into a profiled roofing (metal tile, composite tile);
• TLF. - light tunnel with a corrugated pipe, also has a built-in waterproofing salary for mounting into a flat roofing (bituminous tile, folding roof);
• TWR. - light tunnel with a rigid tunnel tube, for profiled roofing coatings (metal tile, composite tile);
• TLR - Light tunnel with a rigid tunnel pipe, for flat roofing coatings (bituminous tile, folding roof).

Advantages of using light tunnel lights

1. Easy installation and a small amount of installation work.
2. Electricity savings, which is spent on additional lighting of the room (up to 60% on the lighting of the premises of the house).
3. Ability to provide daylight lighting without windows.
4. High durability (manufacturer's warranty 5 years).
5. Light windows of the lantern do not let heat into the room in the summer and cold in winter.
6. Does not consume electricity during operation (with direct appointment, without additional functions),
7. Easy to maintain.
8. The ability to regulate lighting.
9. With the help of proprietary accessories, the light tunnel may have a function of air, as well as used as a lamp at night.

Disadvantages of the use of light tunnels

1. Not very high efficiency in areas with a short light day.
2. In the winter conditions, the probability of snow cover is possible, which for a while leads to the termination of the filing of light rays into the room.

In the photo 8, examples of light tunnels are presented, which are successfully operated.

The SW530 light guide is a hollow tubular lighting (spot zenitic lantern) of the SW series designed for rooms with an area of \u200b\u200bat least 20 m2 with a ceiling height of at least 3 m. Applicat in training rooms, operator, warehouse, laboratories, offices, halls, halls. The SW530 model sampler is suitable for any type of ceiling.

Table of technical parameters:

The efficiency of the fiber of the fiber is at least 82%. At the same time, such positive qualities of natural lighting are preserved, as a continuous spectrum of light, natural illumination rhythm, corresponding to the "biocham" of a person, the natural dynamics of natural light, which allows for judging the weather outside, i.e. Provide maximum connection with the external environment.

The SW530 Light Guide provides lighting on an area of \u200b\u200bat least 30 m2

The SW530 light guide is designed to illuminate large rooms - audiences, training classes, laboratories, conference rooms, cabinets, offices. The solar tunnel replaces 6 lamps like "Armstrong" in the summer and 2 lamp type "Armstrong" in winter. It gives out at least 5,000 lm in cloudy weather and about 11,000 lm on the sun. Through the light guide will not pass the heat of the sun, which means there will be no heating of the room. And the light guide will prevent heat loss and retain the thermal integrity of the building.

The use of solar wells allows you to ensure:

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

Safe lighting of fire and explosive premises;

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

Natural scattered lighting prevents "burnout" of objects and does not distort colors;

Safety for children;

Illumination of garages, storage rooms, toilets, bathrooms and other small rooms.

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

Artificial lighting - is created by electrical light sources. Natural lighting is created by straight solar rays and scattered light of the sky, changes depending on the geographical latitude, time of year and day, the degree of cloudiness and transparency of the atmosphere. Sources of artificial light (IIS) 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 lighting network, there will be no place, which means the placement will not be used for the destination. Lightwater - not dependent on electricity during the daytime, i.e. It is possible to use the placement of the destination until the light is light.

In contrast to windows, artificial light sources do not lose the heat of the building, I perform like fibers your own direct duty - lighting. The light guide is a hollow ring mirror (a mirror tube), which is completely sealed, the possibility of aircraft convection due to the firmware built into it is excluded.

Lighting installation features in any room It often happens that it is not possible to carry out the light into the room which is inside the house and does not have access to the outer walls. Sources of artificial lighting with this problem cope at times as however, fibers that are capable of conducting natural light at a distance of 20 meters deep in the building The light guide can easily highlight any room remote from the roof or the outer wall.

Uniform lighting. Modern lighting sources (LED lamps) are very low uniformity approximate to one. The light guide has a high uniform illumination closer to three.

Pulsation. Any source of artificial light has a stroboscopic effect - in other words there is a ripple. Many have already come across not visual effects of pulsation of artificial lighting, which manifested in the form of a sense of discomfort, fatigue and even malaise, which arise under conditions, at first glance, good, brightly lit rooms or when working at the computer. The light guide is essentially a window or point anti-aircraft lamp and it is like periscope conducts sunlight without distortion and ripples.

Brilliance. Broxity adversely affects the work of the eyes. There are no protection against glossy eye. If there are large brightness of the view function, there is a temporary blinding, which is called a glare. A large degree of glitter can cause vision disorder, headache. Brilliance in production conditions are completely unacceptable. The presence of brilliance in the workplace can lead to industrial injury. The diffuser of the fiber does not have a blinding effect, the light is evenly distributed over the entire area of \u200b\u200bthe room.

Heat crims. The heat dissipation from IIS is not so great, but according to regulatory documents, they must be taken into account. Common heat gain from IIS is no more than 3%. Lightwater transfers heat less than 0.5%, increasing the temperature in the room no more than 0.003 o

Electro- and fire safety The light guide electr- and fireproof. Filter does not need electricity to perform its main function - lighting.

Lack of energy costs The main advantage of the fiber is his direct savings. Jes do not have direct savings and can be content only indirectly.

About S.
The surface of the dome is recommended to wipe with a damp cloth 2 times a year.
It is forbidden to have a physical impact on the product.

Recommendations

For mounting light guides you need:

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

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

Assembling light guides:

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

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

With a high length of the light guide, the pipes are collected segments and are attached at the place. With a small length of the fiber (2-3 tubes), you can collect the entire pipe and mount it assembly.

Additional options and accessories

Svether

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

Light crown

The light crown is designed for additional lighting of rooms with light guides in the dark.

Heliostat "Peresvet"

Heliostat according to the technology of "Peresvet" (developed by Sollarges) represents a fixed panel. Sunlight at low angles during sunrise and sunset, falling on the heliostat is redirected to a mirror tube. The efficiency of the device is at least 90% at angles from 0 to 15 degrees.

The lack of light in the premises is compensated in different ways - additional windows, devices, lamps and the like. One of the innovative solutions of the last time was light guides for lighting. Small devices are installed on the roof or walls, accumulating and delivering the rays inside.

The history of the emergence of light-water lighting

The first attempts to create a light guide for lighting premises were held back in 1874. Russian Electrical Engineering Chicolav Vladimir made a pipe with a mirror surface inside, with the help of the lighting in the dangerous production rooms of the powder plant.

The modern method appeared on the market relatively recently. The first devices conducted by daylight appeared in 2005. The devices passed several stages of improvement. The final version was represented by consumers in 2011.

The light guide is a closed type mechanism for the directional transmission of daylight. Another name is an optical waveguide. Devices are designed in such a way that they may have any curve direction, but it is delivered to the maximum lighting. Allow you to save on electricity and standard light bulbs.

The principle of operation of the light tunnel

Principle of operation of Svetovod

The devices are mounted through the roof, the spherical glass is located (the form is approximate to the attitudes of the attic window). The inner surface of the castoricalen. Thanks to the reflective elements, the light passes through the pipe. Length can be different. The main thing is to go through the floors in the room.

From the bottom (from the side of the room) glass with a scattering effect. Externally, the light tunnel resembles an ordinary lamp. In some models, a light bulb is built at night. Installation in time and cost remains within reasonable limits. In this case, the device saves on electricity and instruments.

Side Glow Method

The system is a light-receiving dome with lenses, which capture and redirect the rays into the light guide

Such a method does not require complex technical schemes, the installation takes a little time, you can do without your own without the involvement of professional installers. The difference is the installation of the projector outdoors, the presence of LED fibers.

Next to the installation should not be the sources of heat. The diffuser is installed from the side walls. Such a location allows you to illuminate the room so that additional sources required during the day. It is relevant for premises without windows (wardrobe, baths, storage rooms, basement). Light guide for LEDs can be made with your own hands.

Method of end luminescence

This method allows you to create the "Star Sky" effect. Small devices are installed under the ceiling, by type of point luminaires. Solar fiber optic light is obtained natural and smooth. Additional plus - It turns out an unusual design.

Tunnels with LED cables are carried out through coatings and can be both solitary and "sprawling". The latter require accurate calculations, the cost is higher than the standard.

What light lights are

Light lamp structure

Light guides work according to this principle: the light is accumulated in the upper spherical part, then the reflective surfaces are supplied inside. Losses range from 10 to 40% on each meter of pipe, up to 40% on bends. The classic version of the light tunnel consists of such parts:

• the dome (round glass is mounted on the roof side);
• roofing;
• reflective pipe (directly light guide);
• diffuser;
• additional details are angular adapters, lamps for night lighting, more.

External parts of the lanterns are performed from durable materials - polycarbonate, plexiglass. Cleaning does not require - enough rain. Collection of light waves is most in cloudy weather, in the evening and in the morning.

Benefits

With proper operation, such lights have a long service life.

Devices every year apply increasingly. Additional natural lighting is installed in industrial premises and private houses. You can install the light guide with your own hands at home. Installation takes little time and strength.

Tunnels allow you to save electricity - according to medium reports, the fibers allow you to spend up to 60% less. With the right installation, the lighting light lamp serves 10 years and more - the manufacturer's warranty is at least 5 years. Devices are thermally insulated - in the summer does not pass warm, in winter, cold (important for residential premises, flower growing and others).

Light tunnels are easy to maintain. It is possible to regulate lighting. Of the additional functions - ventilation, classic lamp (depends on the model).

disadvantages

When covering light guide with snow, its performance can drop to zero

With all the obvious advantages, such mechanisms have several disadvantages with which you should read before installing. The light guide is a device that accumulates natural light. Therefore, for normal operation, a sufficient amount of time is required - tunnels are not suitable for use in places with a short light day.

In winter, difficulties may also arise. If the dome is covered with snow, performance and light-resistant will decrease, sometimes to zero. Therefore, you need to either install another source, or to clean the glass in a timely manner.

The initial installation has a high price. Although this lack is temporary - the usual payback period of 2-3 years, and the operation time is more than 10 years.

Application of light guides when illuminating a private house

Using a light lamp for the illumination of the corridor

Country houses are often equipped with independent power sources, lighting. Light tunnels are suitable for use in different rooms and rooms, allow you to save money, so every year becomes more popular.

Cuisine lighting

The kitchen is a place where the food is prepared and a family is going. Some spend most of the time here. Usually the central light source becomes a ceiling lamp or chandelier. It is impossible to call such a source ideal - there is no light uniformity, flickering artificial light harms his eyes.

Light guides create a multiple natural light that does not irritate the eyes and is more accustomed to the eye. You can set one tunnel or several small ceiling.

Bathroom lighting

Lightwater in the bathroom

The main difference between lamps in the bathroom - safety requirements. High humidity creates conditions in which any source can be used. Electricity is not used in the fibers, no heating or other elements. Therefore, the tunnels are considered the most suitable lighting devices.

The optimal option is to carry out several light lamps. Bright lighting is required at the mirror, where many procedures are held: making makeup, shave and others.

Room lighting

If the room is missing a window, correctly pick up the lamps are almost impossible. No lamp will replace the natural daylight. The decision will be light tunnels. Several lanterns will sufficiently illuminate the room, while not overgrowing the eyes.

Lighting the living room

Lighting living room light guide

This room is considered the most multifunctional in the house. Good lighting is extremely necessary. General sources are not less than local. If there is no possibility to cut the large windows, you can use the fibers. The correct range of waves of the usual eye lighting will help create a cozy atmosphere and save.

Economic efficiency of the introduction of light guides

The main advantage of light tunnels is the savings of funds through an instant reduction in costs and payback. This is noticeable in industrial premises. For example, in buildings of over 100 sq.m. The average consumption per 1 sq. M is 1500 rubles. After installing light guides - the amount is reduced to 600-700 rubles. Warehouses, production pays for the installation of the system in 2-3 years (average).

The choice of light sources depends on the type of room, the possibilities and preferences of the owners. Light guides are an alternative lighting method that is suitable for any room.
