SUNperformance - home edition by Green Lighting
This simple and ingenious system consists of only 4 components:
- a dome to collect the light
- a reflector pipe for the light transport
- a spreading disc to distribute the light in the space and
- an insulating unit against heat loss and the formation of condensation.
The advantages of a hemispherical dome:
- total reflection is avoided
- the surface to receive the light is larger
- dust and light dirt are "rained" clean
- Inward-directed prism structures do NOT enlarge the external surface
- Grooves and structures on the inside prevent the flow of condensation water
- Additional domes (e.g. double shell) reduce the incidence of light
- Reflector panels in the dome reduce the diffused incidence of light
CONCLUSION: PAY ATTENTION TO THE CORRECT DOME
Properties of the light tube:
- the degree of reflection over the entire visible spectrum is 98%
- mechanically robust, because it is coated in high vacuum with ultra-pure silver of 99.95% quality
- the surface scattering is less than 4%
- Manufacturer's guarantee on the surface of 25 years
CONCLUSION: PAY ATTENTION TO THE CORRECT COATING OF THE LIGHT TUBE
The advantages of the spreading disc (diffuser):
- it has a very high light transmittance of approx. 92%
- it scatters the light and makes it diffuse
- choice between glass and acrylic
- seals between the tube and the spreading disc and between the borders and the cover
CONCLUSION: PAY ATTENTION TO THE SEALS ON THE DIFFUSER
The advantages of BLUEperformance:
- the system is thermally decoupled
- there is no thermal bridge
- the heat loss is reduced to a minimum
- there is no formation of condensation from the ascending warm air
CONCLUSION: DO NOT USE A DAYLIGHT SPOT WITHOUT BLUEPERFORMANCE
