For our planet the sun is a major lighting source. The lightwhich we receive on earth varies in intensity and quantitydepending upon the geographical location on earth.

For normal human activities inside the building what we requireis indirect light. There is a major difference between directand indirect light. Direct light from the sun produces light inhigh quantities but also generates a lot of heat, which may notbe required or at sometimes can be uncomfortable.

Indirect lighting produces a good quality diffused light byeliminating the heat that's being produced from sunlight.Interior designers always look for various ways that willincrease the chances of achieving good quality sunlight into aroom.

the basic principle behind indirect lighting is easy. Obstructthe direct sunlight on a surface that will absorb the heat andthrow our or disperse the light alone uniformly inside the room.

This requires a good study of various light entry points of agiven room and selecting surfaces that will receive directsunlight. Then applying finishes to these materials that willabsorb the heat but at the same time reflect a lot of light tothe interiors.

There is a major challenge in doing this.

Let's say that I select a bedroom to be treated for indirectlighting. I select a plane wall opposite or adjacent to thewindow opening that will receive direct sunlight. If I paint thewall with a bright color, it will definitely reflect the lightin the entire room, but at the same time create a "glare" thatcan be quite uncomfortable for the users.

So just creating reflecting surfaces is not the solution. Thesurfaces that will reflect the direct light and at the same timewon't produce a glare are recommended here.

This can be easily achieved using artificial lighting. Thegreatest advantage of artificial lighting is that you can selectthe number of light sources in

the first place. Then lightsources can be very creatively be hidden using shaders and otherdesign elements, so that the light spots can be directed towardsreflective surfaces.

A very common use of this technique is, project the light spotson a bright reflective ceiling and the ceiling will uniformlydisperse the light in the rest of the room. Projecting the lighton ceiling will eliminate the problem of causing glare, sincethe ceiling is always above the normal eye level.

Using a centralized light source on the ceiling and throwing thelight on adjacent walls is also a good solution. This will alsosave a lot of wiring lengths, cutting your cost in the fixing upof the total electrical system.

A careful choice of reflective surfaces inside a room cangreatly enhance the light qualities in a room. In interiorsthere are hundreds of objects that receive light. Objects suchas walls, furniture ceiling, floor will have a tendency toreflect light away from them. Objects like windowpanes, glasspanels in the furniture will absorb or will allow the light topass away the light thought them b reducing the heat andintensity of light.

That's why careful selection of materials during design stagecan cause a good lighting solution. Also the lighting solutionwill differ from room to room depending upon which direction theroom faces outwards. For this the sun path must be taken intoconsideration. By careful study of the sun path it will be easyto decide the color schemes and finishes for satisfactory resultin indirect lighting.

I hope this article was helpful to everyone.
