Day Lighting

Using the light from the sun to illuminate the buildings for 8-10 hours during the day is called day lighting.

Day lighting has many benefits

Energy Benefits

  • Reduces electrical costs
  • No maintenance costs
  • Zero cost inflation

Health Benefits

  • Improves health and well-being
  • Reduces eye strain

How it works

The day lighting system consists of three components

  • Light Collector:

The light from the sun is collected and diverted effectively into the tube by the collector.

  • Reflective System:

The reflective tube efficiently transmits the maximum light without any loss up to the diffuser.

  • Light Diffuser:

The diffuser blocks the heat and disperses the light uniformly inside the building.


Some Actual Light Pipe Applications

Day lighting provides cool natural light to illuminate the interiors of a building. If effectively used, it provides excellent light for almost 10 hours – from 8 am to 6 pm. During this time, the electricity is not needed. The sun itself provides the light – without any heat. A typical single Light Pipe can illuminate approx. 500 sq.ft
