The Lightpipe® is an innovative technology for daylight transportation and Energy efficiency in buildings. It has a Sunlight capture system (Light collector), light transfer pipe and double glazed light diffuser. The entire system can deliver light into building spaces for a length of 12 meters. “To Successfully daylight a space, the day lighting system should optimize sunlight collection to given climatic region. Sunlight collection system designed for certain regions are Not effective in other climatic regions.” Skyshade provides optimized design for light collection systems specific to the regions. The Lightpipe solar lighting system delivers clean, light energy into building spaces giving a feeling of well-being and saving electrical energy for lighting during Daytime. It delivers sunlight without any colour shift.
How it Works
This tubular daylighting system can capture ambient Sunlight when mounted on roof top or side wall of the buildings. The collected light is ‘piped’ through pipes or ducts to longer distance up to 12 meter(40 feet). The transported light is delivered to the end light diffuser into the space.
The working principle is as follows:
High impact strength, UV stable, light collector collects sunlight from all directions and delivers light effectively throughout the day even at low sun angles.
The speciality reflective system delivers high luminance with minimal light loss, without color shift even on cloudy day.
The intensified sunlight in Lightpipe® is controlled and distributed into indoor spaces by light diffuser.
- Light capture is high at low sun angles, i.e before 9am and after 3pm.
- Extended daylighting hours.
- No heat build up.
- Uniform light dispersion.
- Daylight can reach the false ceiling covered areas.
LEED & GRIHA Ratings
Daylighting improves LEED ratings of green buildings. Points can be scored on aspects of daylight availability, controls, Renewable energy and etc. in green buildings.
- Low angle sunlight (morning & Evening) is boosted
- Light pipe delivers more uniform day lighting throughout the day
- Midnoon sun radiation is partially rejected
- Blocks UV radiation
- High impact strength
- No change of light color
- Durable & long life
- Maintenance free
“The success of the day lighting system lies not just in light collection, but in effective distribution of collecting light energy in a given space.” SkyshadeTM provides three options light diffusers that can suffice all requirements. Be it a high open ceiling industrial/ware house building, a processing area office space or residence. The diffusers provide the right amount of light distributed in a space.
“Ability to control sunlight delivered into building space is key to Human Comfort” Light pipes are equipped with dimmer arrangements operated manually or motorized to reduce the Daylight. Areas of privacy, conference rooms & office areas require the dimming arrangement.
Integration with Electrical lighting
SkyshadeTM provides complete solution of controls for Electrical lighting to switch off them when daylight is available. “Studies on daylighting systems show that 30-50% more energy saving potential can be realized when Daylighting is fully integrated with Electrical lighting.” In existing buildings where LightPipes are installed. The electrical lights can be simply switched on/off by Day light sensors depending on daylight provided in a space. In electrical lighting with dimmable hardware more precise control can be done. New buildings where light pipes are being planned, It is recommended to have dimmable Electrical lighting systems and be integrated with light pipes- Day lighting system. This arrangement ensures that irrespective of ambient light constant light flux is made available to building occupants.
