The Miracle Daylight System
"Harvesting Sunlight without Heat"

Working long-term in electric lighting is believed to be deleterious to health, working by daylight is believed to result in less stress and discomfort.

 

A pipe that conducts ambient sunlight to desired location in the building interiors.

DLPS first to offer Daylighting solutions in India.

     

 

How it works?

 

Light Collector

 

  • Highly durable and inflammable polymeric material, UV resistant, Light collector collects daylight from all angels and transfers the light effectively throughout the day, year on year..

 

Reflective System

 

  • Corrosion resistant High reflectance coating transfers above 90% of light without colour shift about 300 days. It increases light input at low angles for greater light output.

 

Light Diffuser

 

  • The light diffuser disperse the light uniformly without bright spot, glare and no colour shift
.

FAQ'S

 

How does the DLPS LightTube daylighting system work?

The lightTube 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 LightTube 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 LightTube delivers 1400-1500 lux.

 

How about the Heat?

Unlike regular Skylights, the lightTube 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 LightTube 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 LightTube system is?

The system life expectancy is 20 years.

 

Can the LightTube 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 LightTubes are to be weather protected. The southern face of building can be tapped to bring the light inside.

 

Can the LightTube System work for basement application?

Yes, the LightTube daylighting System can enter from side wall. All it needs a shadow free area to tap the external Sunlight. The LightTube to be weather protected.
