Original crystal sun tunnel with maximal light power during the whole day
The unique sun tunnel with Lightway Crystal dome
The basic kit of the sun tunnel includes all components for construction of the sun tunnel.
The basic kit includes:
Crystal dome with roof flashing and accessory for complete assembly of the roof part of sun tunnel
1 piece of 625 mm long reflective tube for bringing the light from the dome to the interior
Glass diffuser (for light spreading) with a white trim for the assembly into the ceiling
Assembly accessory
In case you need to have bent or extended light tube (the direction change of conduction of the tube), it is necessary to buy required amount of extension tubes and adjustable elbows!
If you need help with sun tunnel assembly, please contact our customer service.
Glass dome made of Bohemian Crystal
The sun tunnels Lightway Crystal are unique, thanks to the crystal dome. It is made of Bohemian crystal and it collects 30% more natural daylight that polycarbonate equivalents. It is resistant against aging even in intense U.V. light and weather conditions. The crystal and the design of the dome have an ability to collect daylight even when it is cloudy and it does not distort natural colours of daylight.
The surface of the crystal is polished and hard, so smog or impurities do not stick to it, that’s why it needs almost no maintenance. The crystal dome does not turn yellow after a few years and imits the same light for decades.
Optical attributes of the dome are well designated, so it keeps hi performance light collection even if it is cloudy. That’s why it provides great light through the sun tunnel the whole day.
High reflective light tube and adjustable elbow
Inside of the Lightway tube there flows sunlight into the interior. The inside walls of the tube are created by extremely powerful mirrors with maximum light reflectivity.
The inside reflective layer is made of silver and silicon oxide, which are fixed by chemical vapor deposition in a vacuum. The layer will not or peel it or be warped by changes of temperature and humidity.
Connecting the light tube to the adjustable elbow, Blue Performance insulation and a dimmer is easy due to systematic connections, which is a standard part of package.
Technical information:
reflection of reflexive layer of the pipe 99,8%
ray diffusion during reflection in 45 angle in pipe <6%
the basic material is aluminum, 99,7%
overall maximum distance of sun pipe is up to 80 meters, including 2 adjustable elbows 90° direction change of the conduit. The conduit of the tube can be vertical or horizontal without any effect on performance.
The loss of light affected by tube lenght can be as little as:
within 10 meters 0,5%
more than 10 meters 0,7%
Glass ceiling diffuser – light diffuser
The glass diffuser spreads light through the room and it prevents direct
glare of light in interior. It is made of glass, that’s why it doesn't turn yellow and it lets the sunlight through well without any loss on light intensity and any change on the color spectrum. The diffuser is already assembled with the tube of the length 200mm. It is easy to connect the light tube to isolation element Blue Performance and a dimmer.
it is made of sodium-potassium glass
does not turn yellow, does not change color spectrum
white color trim
Additional LED light
It is used for illumination in the time of year when it is dark outside. Your sun tunnel Lightway will do the function of the sun tunnel as well as the ceiling light.
LED strap will be easily stuck in two threads on the inside of pipe above the ceiling diffuser.
Standard chromaticity of the light is warm white.
