how sun tunnels work

Crystal sun tunnels Lightway

bring the Sun into your house

They collect sunlight

The sun tunnels collect daylight on the roof, fasade, terrace or even on the pavement or green roof. Thanks to glass dome made of crystal glass CRYSTAL, the light flows into the interior pure and without any changes with maximal intensity.

They conduct daylight

Special high reflective pipe Lightway conducts light into the interior. Inside of the pipe is made of high power mirrors with maximal reflection. The light flows into the interior with minimal looses.

It shines up the interior with sunlight

The pipe is places on the ceiling or on the wall of the room you need to shine up. It is provided with a diffuser, which spreads the light into the interior well, so it doesn’t dazzle you.

Roof dome – the light collector

The dome collects the sun rays on the roof and sends them to the sun pipe, even if it is cloudy. The roof dome Lightway CRYSTAL is made of Bohemian crystal and it practically doesn’t get old. Compared to the plastic dome it is resistant to aging, even when the UV light affects it. Crystal has a strong ability to collect daylight, even if it is cloudy outside, and it doesn’t change the natural colors of daylight. The surface is hard and smooth, the smog or impurities are not clinging on it, that’s why it needs almost no maintenance. The crystal dome does not turn to yellow after few years and it lets out the light the same for decades. The surface is self-cleaning every time it rains, because the smog and dust is not baked on the surface.

High reflective pipe

The sunlight flows like water inside of the pipe Lightway. Inner walls of the pipe are made of high power mirrors with maximal reflectivity of light. The inside reflective layer is made of silver and silicon oxide, which are fixed by chemical vapor deposition in a vacuum. The layer mustn’t crack or peel or be warped by changes of temperature and humidity. The light pipe can be bent using an adjustable elbow. Due to its enormous directional reflectivity and low decay, it can bring the light up to 50m far from the dome.

Glass diffuser

The glass diffuser should avoid glaring and it should spread the sun rays equally across the room so the light comes through the whole room. The diffuser softens the power of light rays and spreads it equally. Quality diffuser is made of glass and that’s why it lasts many years the same. It doesn’t get yellow, it is resistant to scratches and it transmits the daylight without any looses on light intensity. The light stays clear and it keeps its natural color spectrum.



Blue performance

Blue performance

The insulation element Blue Performance into climatically difficult areas. It avoids thermal leaks during the winter and in summer it protects against overheating. It prevents the humidity condensation in temperature changes and it makes the connection to thermal insulation of the house easier.

Additional light

Přídavné osvětlení

The additional LED light replaces daylight when the sun is not shining. In normal size rooms, it is possible to replace a chandelier with the LED light.



Sometimes, there is a need to shut the sun down. That’s why we offer a dimmer, which you can use for light regulation, or for complete shutdown. The dimmer has similar function like sunblind.
