FAQ'S

 

How does the DLPS LightPipe daylighting system work?

The lightpipe daylighting captures the sunlight from roof top and pipes it down through reflective tubing to the interior space. The diffuser at the end of tubing distributes the light in all directions.

 

How about overcast/Cloudy day?

The Lightpipe day lighting system provides good performance even in cloudy days. Our silver coated tubes transfer the maximum amount of sunlight into the room in diffused weather conditions. In overcast conditions where ambient light is 40,000-50,000 lux, 530 mm LightPipe delivers 1400-1500 lux.

 

How about the Heat?

Unlike regular Skylights, the lightpipe day lighting system conducts light only and not heat because of static air column. As the length of Reflective tubing increases, the heat transfer reduces. Even double glazed diffusers can be provided.


How about UV radiation?

The LightPipe System has a top UV absorbing polycarbonate dome and bottom diffuser which absorbs 99% UV radiation. The light transmitted will not fade the interiors of building and not harmful.


How durable the LightPipe system is?

The system life expectancy is 20 years.

 

Can the LightPipe System work for Lower Floors in Multilevel building?

Yes, if there is a duct or opening for the tubes to run through from roof. The lightpipes are to be weather protected. The southern face of building can be tapped to bring the light inside.
